RESUMEN

AIM: To evaluate the risk factors associated with caries development after full-mouth rehabilitation for early childhood caries (ECC) under general anesthesia. MATERIALS AND METHODS: A total of 100 children diagnosed with ECC requiring full-mouth rehabilitation under general anesthesia were recruited for the study. At baseline, caries status, plaque index, Streptococcus mutans count, and Lactobacillus count were evaluated. The risk assessment for caries was evaluated using a cariogram. Children were recalled after 12 months for evaluation. All children returned for the recall and data was recorded at the recall visit. Children were grouped into caries-free or caries recurrent based on the absence or presence of caries. Chi-square tests and student's t-test were used for statistical analysis using the statistical package for the social sciences (SPSS), version 23. RESULTS: All 100 children returned for follow-up. 76% of the children developed new carious lesions in a period of 1 year. A statistically significant association between caries recurrence and S. mutans count and caries risk assessment (CRA) score was found (p < 0.001). No significant associations were seen between parental education levels and the oral health practices of the child. CONCLUSION: Children treated under full-mouth rehabilitation for ECC under general anesthesia are at risk for developing new carious lesions after treatment. New carious lesions are strongly correlated with the presence of S. mutans, and high cariographic risk scores serve as an indication of future caries. Early childhood caries may be avoided if children are more diligent in practicing good dental hygiene. CLINICAL SIGNIFICANCE: Relapse of caries after full-mouth rehabilitation under general anesthesia can affect the quality of life of children. Preventive measures should be initiated and reinforced to prevent the occurrence of new carious lesions after full-mouth rehabilitation.

RESUMEN

OBJECTIVES: This project examined patterns of adult patient management using a caries risk assessment (CRA) protocol at East Carolina University, School of Dental Medicine. Usage of the CRA protocol from 2014 to 2019 was assessed. Non-operative anti-caries treatments were measured against caries risk status (high, moderate, low, or none). Steps to improve the appropriate management of patients based on caries risk are presented to align with accreditation standards for predoctoral education programs. METHODS: The CRA protocol is based on the Caries Management by Risk Assessment approach. Risk-based patterns for two non-operative interventions were examined: (1) prescriptions for 0.12% chlorhexidine gluconate (CHX) mouth rinse and (2) prescriptions for 5000 ppm fluoride toothpaste (PreviDent 5000 [PreviDent]). Statistical analyses included chi-square tests and logistic regression. RESULTS: Over the study period only 16.4% of adult patients had completed the CRA form. Among 29,411 patients from nine community sites, treatment rates for PreviDent were 18.7% among high-risk patients, 11.6% for moderate-risk adults, and 6.4% for low-risk adults (p < 0.01). Treatment rates for CHX were 23.0%, 22.6%, and 17.1%, respectively (p < 0.05). Patients without a CRA status were least likely to receive any anti-caries treatments, indicating that CRA status affects clinical, non-operative care. CONCLUSIONS: Patterns for prescription of PreviDent and CHX are consistent with CRA status. Future efforts to improve usage of the CRA protocol using faculty calibration, tracking with quality improvement tools, and reassessment. Training in the community-based educational setting is enhanced through data-based tracking to assure evidence-based decision making.

RESUMEN

BACKGROUND: For caries risk assessment (CRA) tools for young children to be evidence-based, it is important to systematically review the literature to identify factors associated with the onset of early childhood caries (ECC). AIM: This updated systematic review aimed to identify current evidence on caries risk in young children. DESIGN: A comprehensive and systematic literature search of relevant databases was conducted to update a previous systematic review and identify risk factors associated with ECC. Potential risk factors were identified based on strength of association using odds ratios, hazard ratios, relative risk, etc. GRADE was used for rating quality evidence through consensus. RESULTS: Twenty-two studies met inclusion criteria for the search from mid-2017 to 2021. Twenty-five publications from the prior systematic review, from 1997 to mid-2017, were also included. Several socioeconomic, behavioral, and clinical variables were identified as ECC risk factors. Factors included the following: age, socioeconomic status, frequency of and supervised toothbrushing, fluoride exposure, breast- and bottle-feeding, feeding habits, absence of a dental home, past caries experience, active non-cavitated lesions, visible plaque, enamel defects, and microbiome. CONCLUSION: This study provides updated evidence of risk factors for ECC that could be included in CRA tools.

RESUMEN

OBJECTIVE: Caries Management by Risk Assessment (CAMBRA) is a questionnaire used to diagnose the patient's overall caries risk. This study aimed to present a self-assessment questionnaire based on CAMBRA which, unlike the original, is completed by parents/caregivers, without the need for a dental examination, allowing a presumptive diagnosis to be established in children under seven years of age excluded from the oral health programme of the National Health System to establish individualised recommendations for caries risk and their early inclusion in preventive programmes of the Madrid Health Service (Madrid, Spain). METHODS: A cross-sectional observational study was carried out following STROBE guidelines using for the first time a self-assessment questionnaire based on CAMBRA in a population of children aged from three to six years from a nursery school in Madrid (Spain). The results were analysed using descriptive statistics and Fisher's exact statistic was used to study the relationship between qualitative variables. RESULTS: The questionnaire was answered by the parents of 120 children (response rate=53.1%), of whom 40.8% presented a low a priori caries risk, 42.5% a moderate risk and 16.7% a high caries risk. CONCLUSIONS: The present study allow the identification of patients at risk of presenting and/or developing caries. However, future studies should evaluate its sensitivity and specificity by comparing it with a confirmatory diagnosis after a dental examination. Nevertheless, the modified CAMBRA questionnaire could be a useful tool for population screening, facilitating the access of the population at risk of caries and risk of exclusion to preventive and community plans.

OBJETIVO: Caries Management by Risk Assessment (CAMBRA) es un cuestionario de diagnóstico del riesgo global de caries dental. Este estudio tuvo como objetivo presentar un cuestionario de autoevaluación basado en CAMBRA que, a diferencia del original, es cumplimentado por padres/madres/cuidadores, sin necesidad de una exploración odontológica, permitiendo establecer un diagnóstico de presunción en menores de siete años excluidos del programa de salud oral del Sistema Nacional de Salud, con el fin de instaurar recomendaciones individualizadas al riesgo de caries y su inclusión precoz en programas preventivos del Servicio Madrileño de Salud (Madrid, España). METODOS: Se llevó a cabo un estudio observacional transversal basado en las recomendaciones STROBE, empleando por primera vez un cuestionario de autoevaluación basado en CAMBRA en niños/as de tres a seis años de una escuela infantil de Madrid (España). Los resultados se analizaron mediante una estadística descriptiva y para el estudio de la relación entre variables cualitativas se utilizó el estadístico exacto de Fisher. RESULTADOS: El cuestionario fue respondido por padres de 120 niños, de los cuales, el 40,8% presentó, a priori, un riesgo de caries bajo, el 42,5% un riesgo moderado y el 16,7% un riesgo alto de caries. CONCLUSIONES: El presente estudio permite la identificación de pacientes en riesgo de presentar y/o desarrollar caries. No obstante, futuros estudios han de evaluar su sensibilidad y especificidad mediante su comparativa frente a un diagnóstico de confirmación tras una exploración odontológica. Pese a ello, el cuestionario CAMBRA modificado podría ser una herramienta útil para el cribado poblacional, facilitando el acceso de la población en riesgo de caries y en riesgo de exclusión a planes preventivos y comunitarios.

RESUMEN

Introduction: Caries are at the forefront of childhood diseases. Although childhood caries is usually not life-threatening, it can affect children's dental-maxillofacial development and mental health and place significant financial and psychological burdens on parents. As the focus of childhood dental caries shifts to early diagnosis and prevention rather than restorative dentistry alone, screening children at a high risk of dental caries is urgent. Appropriate caries prevention measures and treatment sequences can effectively reduce the occurrence and development of dental caries in children. Case: We report the case of a 7-year-old boy presenting with a high risk of dental caries involving multiple primary teeth and premature eruption of the permanent teeth. We shifted the caries status of the child from high to moderate likelihood. At the 9-month post-treatment follow-up, the patient had no new dental caries, and the length and width of the dental arch were effectively maintained. Conclusion: Oral health education, dental plaque removal in a regular basis, and fluoride application contribute to caries management.

RESUMEN

In order to optimize dental education, established procedures for caries diagnosis and therapy, such as the International Caries Classification and Management System (ICCMS), should be integrated into the curriculum. In preparation, the level of knowledge of dental students on caries detection and management was surveyed in order to specifically address deficits in dental teaching. In addition, the data were compared with the knowledge of clinically experienced dentists. The results are presented in this report and possible consequences for dental teaching are discussed.Twenty-six sixth semester dental students and six assistant dentists at the Department of Orthodontics (Philipps University of Marburg, Germany) were available for the written survey during the winter semester 2018/2019. For 12 anonymized orthodontic patient cases, the clinical findings, caries risk, and adequate treatment were to be determined for each defined tooth. The consensus decision of two experienced dentists served as the reference value. As a result, agreement with the reference ranged from 40.7% to 51.3% for students and from 56.9% to 75.0% for assistant dentists. The extent of caries and the resulting necessary treatment were mostly underestimated.In addition to theoretical knowledge, clinical experience is another prerequisite for adequate caries diagnosis and its management. The underestimation of caries extent and necessary treatment should be taken into account when teaching content. Procedures such as the ICCMS should be integrated into the dental curriculum at an early stage, so that orthodontic patients can also receive effective care.

RESUMEN

Individuals with dementia can present with varying challenges depending on their state of disease. The individuals caring for them may be faced with resistant behaviors when trying to provide adequate oral care. A poor oral condition can lead to decreased caloric and fluid intake causing multiple comorbidities to be exasperated due to the declining oral condition. Creating a management plan and an oral disease prevention plan are key to improving the overall health outcomes of these patients.

RESUMEN

Background: Minimally invasive dentistry (MID) includes caries detection using caries risk assessment (CRA), early localization of nascent carious sores including necessary and voluntary avoidance, and remineralization of demineralized veneer and dentin when diagnosed early for these reasons. Although the dentistry curriculum prioritizes the benefits of MID in tooth protection, this research is seldom included in classroom instruction. Aim: The purpose of this research was to gauge the level of understanding that dental professionals have about MID ideas. Methods: An online questionnaire measuring MID knowledge and application was used to compile the data. The Chi-square tests were run for statistical analysis in the Statistical Package for the Social Sciences (SPSS). Results: Just 42.2% of the dentists who replied had MID training during their undergraduate or internship years, and the majority of that training came via lectures (45.2%). The majority (almost 81%) of respondents believed that CRA should be performed on all patients. Differences in knowledge and experience with atraumatic restorative therapy and the sandwich approach for treating caries in permanent teeth and high caries risk children were shown to be statistically significant (P 0.05). Conclusion: Dentists know about the benefits of MID, but their patients are not reaping those benefits since so many dentists still use the old methods of treating complete caries.

RESUMEN

AIM: To evaluate the distribution of caries risk category of patients at a dental institution and determine adherence to providers' recommendations. MATERIALS AND METHODS: A cross-sectional retrospective review of 1,235 patients records that included data collection on demographics, the sum of the number of decayed, missing due to caries, and filled teeth in the permanent teeth (DMFT), presence of frequent snacking, stimulated salivary flow rate, stimulated saliva pH, saliva buffering capacity, biofilm activity, caries risk category, anti-caries prescription accept/decline, and change in the caries risk category. Statistical analysis was carried out through Pearson's Chi-squared test and linear model ANOVA with a significance level of 0.05. RESULTS: Pearson's Chi-squared test showed a statistically significant difference in frequency by risk category (p < 0.001) indicating that patients were skewed toward high and extreme caries risk. Linear model ANOVA showed that higher risk categories were associated with lower salivary flow rates (p = 0.010) and higher biofilm activity (p < 0.001). About, 1 out of 3 patients were reported to have frequent snacking (N = 391, 32%). Frequent snacking patients were more likely to present with higher caries risk assessment (p < 0.001), younger age (p < 0.001), and female (p < 0.001). Despite recommendations from the dental student provider, only 27% accepted the anti-cavity prescriptions while 61% declined the recommendation. CONCLUSION: Distribution of caries risk category is not evenly distributed, but rather skewed toward high and extreme caries risk levels. Despite the identified risks, there is low adherence to the recommendations provided by healthcare providers. The results underscore the necessity for targeted interventions and initiatives aimed at fostering behavioral changes to enhance oral health outcomes. CLINICAL SIGNIFICANCE: There is a high need for targeted interventions and initiatives that promote behavioral changes to enhance oral health outcomes.

RESUMEN

OBJECTIVE: This cross-sectional study assessed the implementation of documenting a baseline caries risk assessment (CRA) of patients seen by predoctoral dental students and its association with the presence of caries risk management (CRM) treatment. METHODS: A convenience sample of 10,000 electronic axiUm patient records at Tufts University School of Dental Medicine was retrospectively assessed for the presence or absence of a completed CRA and CRM after IRB approval following predetermined inclusion and exclusion criteria. The CRM variables (nutrition counseling, sealant, fluoride) were identified by procedure codes that were completed by the student. Associations were assessed via the chi-square test, Kruskal-Wallis test (with Dunn's test and the Bonferroni correction used in post-hoc tests) and Mann-Whitney U test. RESULTS: Most patients (70.5%) had a CRA completed. However, only 24.9% (out of the 7045 patients with a completed CRA) received CRM, while 22.9% of the 2,955 patients without a CRA received CRM. The difference between the groups with and without a completed CRA in terms of the percentage receiving CRM was not clinically significant. Significant associations were found between a completed CRA and in-house fluoride treatment (p = .034) and between a completed CRA and sealant treatment (p = .001). Patients with higher baseline CRA levels (i.e., greater risk) were more likely to have CRM (16.9% of the 785 patients at low risk, 21.1% of the 1282 patients at moderate risk, 26.3% of the 4347 patients at high risk, and 32.6% of the 631 patients at extreme risk). The association between these two variables was significant (p < .001). CONCLUSION: There is evidence that students were mostly compliant with completing a CRA for most patients; however, there is a deficiency in implementation of CRM approach to help support dental caries management, and there is still much room for improvement.

RESUMEN

Introduction: Early Childhood Caries (ECC) can affect the health and quality of life of the children. Assessing a patient's risk of developing caries is an important aspect of caries management; however, can assessing the caries risk predict the impact of ECC on the OHRQoL? Few Indian studies have reported association between caries status, risk, and the impact on OHRQoL. Aim: To assess the association between dental caries status, risk assessment, and OHRQoL in 3-6-year-old children. Methodology: A total of 50 healthy children were recruited in a cross-sectional study. Parents filled the ECOHIS questionnaire. Caries status, risk, and OHRQoL were measured as dmft-pufa, CRAFT (Caries Risk Assessment for Treatment- an indigenous tool) and ECOHIS scores, respectively. Results: Moderate correlation was seen between dmft and ECOHIS scores (r = 0.496, p < 0.01), and pufa and ECOHIS scores (r = 0.408, p < 0.05). More number of subjects with higher scores of ECOHIS were in the high-risk category of CRAFT (p < 0.05). Conclusion: Caries status, risk and OHRQoL were associated in 3-6-year-old children. Thus, caries risk assessment may predict poor OHRQoL. How to cite this article: Iyer CR, Jawdekar AM.

RESUMEN

Introduction: Early childhood caries (ECC) is a chronic but preventable disease affecting young children worldwide. Many young children face access to care barriers to early preventive dental visits for a variety of reasons, which can increase their risk for ECC. Non-dental primary health care providers are well positioned to assist in assessing a child's risk for ECC by performing caries risk assessment (CRA). The purpose of this project was to report on primary health care provider and stakeholder feedback in order to refine a drafted CRA tool for Canadian children <6 years of age intended for use by non-dental primary health care providers. Methods: In this mixed methods project, we conducted six focus groups with primarily non-dental primary health care providers followed by a short paper-based survey to quantify preferences and feedback. Data were thematically and descriptively analyzed. Results: Participants' feedback on the drafted CRA tool included the need for it to be relatively quick to complete, easy and practical to score, easy to implement into practitioners' clinic schedules, and to include anticipatory guidance information to share with parents and caregivers. All participants (100%) welcomed a CRA tool. Many (85.4%) liked a layout that could be added to tools they already utilize. Most (73.2%) wanted the tool to be in colour, and many (90.2%) wanted the tool to include pictures. Conclusion: Non-dental primary health care providers informed the final development and layout of the newly released Canadian CRA tool. Their feedback resulted in a user-friendly CRA tool with provider-patient dynamics and preferences.

RESUMEN

OBJECTIVE: To develop clinically applicable methods to characterize occlusal topography and assess possible associations between morphology and caries incidence and development. DESIGN: In this retrospective clinical study, we evaluated caries presence and severity pre- and post-orthodontic treatment for first molars of 147 patients (384 teeth). These teeth were previously scanned using a clinical intraoral scanner, and the obtained digital elevation models were used to 1) analyze the 3D occlusal surface parameters (n = 384) and 2) quantitatively characterize the mandibular molars' (n = 166) fissure patterns using three novel methods. Pearson correlation coefficients were calculated to evaluate the associations among the measurements, and presence/severity of caries pre- and post-treatment were assessed using generalized linear mixed-effects models. RESULTS: Robust quantitative fissure characterizations were developed, and reliable occlusal surface parameters were obtained. In the studied population, none of the parametric measurements (Slope: p = 0.62 for presence, p = 0.96 for severity; Relief Index (RFI): p = 0.36, p = 0.84; Orientation Patch Count rotated (OPCr): p = 0.48, p = 0.13; Dirichlet Normal Energy (DNE): p = 0.91, p = 0.15) or the fissure morphological measurements (Mesial Angle: p = 0.43; Distal Angle: p = 0.86; Average Angle: p = 0.52; Area Difference: p = 0.83; Percent Fissure: p = 0.68) were found to be significantly associated with caries status or severity. CONCLUSION: Despite the lack of correlation in the limited studied sample, the tools developed to characterize occlusal surface topography and fissure morphology have the potential to be used in more comprehensive clinical evaluations.

RESUMEN

OBJECTIVES: To investigate caries risk assessment (CRA)-related knowledge, attitudes, and practices among dentists in China, to describe their subjective ratings of the significance of specific caries risk factors and to identify factors associated with the level of knowledge, attitudes, and use of CRA in routine clinical practice. MATERIALS AND METHODS: A cross-sectional anonymous online questionnaire survey was performed. The questionnaire was distributed via WeChat (Tencent, Shenzhen, China) to practicing dentists between November 25 and December 25, 2021. For participant recruitment, we employed purposive and snowball sampling techniques. Data were collected using a specialized web-based survey tool ( www.wjx.cn ) and analyzed with descriptive statistics and regression analyses. RESULTS: A total of 826 valid questionnaires were collected. Only 292 (35.4%) respondents used CRA in routine practice, among whom a majority (243, 83.2%) did not use a specific CRA tool. The routine use of CRA was associated with the type of practicing office, attendance of caries-related lectures, the habit of reading caries-related literature, geographic location, and the total knowledge score. The mean total knowledge score was 3.13 (score range: 0 to 6). Knowledge levels were related to several sociodemographic characteristics, including geographic location, the type of practicing office, attendance of caries-related lectures and the habit of reading caries-related literature. The risk factor deemed most important was "current oral hygiene." CONCLUSIONS: Caries risk assessment has not widely entered clinical practice in China. The level of CRA-related knowledge among dentists was generally suboptimal. CLINICAL RELEVANCE: Strengthening CRA-related education may allow practitioners to develop a better understanding of caries risk assessment and hence promote its implementation.

RESUMEN

BACKGROUND: Oral health is influenced by social determinants of health (SDH), predisposing people and communities to greater risk of developing caries. This study evaluated the association between caries risk in adults and SDH such as ZIP Codes, systemic diseases, payment methods, and race or ethnicity. METHODS: The BigMouth Dental Data Repository (n = 57,211) was used to extract clinical and SDH data from patients' dental electronic health records for 2019. Caries risk categories were used as ZIP Code data was merged with the Social Deprivation Index, a composite measure of area-level deprivation based on 7 demographic characteristics collected in the American Community Survey. RESULTS: The results showed that the odds of being in the high caries risk group were higher for people in the 49- to 64-year age group (adjusted odds ratio [aOR], 2.24; 95% CI, 2.08 to 2.40; P ≤ .001), men (aOR, 1.19; 95% CI, 1.13 to 1.25; P ≤ .001), people who had comorbidities (diabetes: aOR, 1.16; 95% CI, 1.08 to 1.24; P ≤ .001; cardiovascular disease: aOR, 1.40; 95% CI, 1.32 to 1.50), and people with an Social Deprivation Index score above the 75th percentile (aOR, 2.39; 95% CI, 2.21 to 2.58; P ≤ .001). In addition, Hispanic and Black people had higher odds of being at high caries risk than other races or ethnicities (Hispanic: aOR, 3.05; 95% CI, 2.32 to 4.00; Black: aOR, 2.05; 95% CI, 1.02 to 4.01). CONCLUSIONS: This study shows the association of caries risk with higher social deprivation, reinforcing the role of structural and upstream factors in oral health. This study is unique in using recorded ZIP Code information and assessing caries risk levels for those regions. PRACTICAL IMPLICATIONS: The physical and structural environment should be considered contributors to caries risk in people.

RESUMEN

Aim: Early childhood caries is the most common chronic infectious disease in children in the United States. This study, which is part of a larger, longitudinal study exploring oral microbiological components of caries development in children, reports on the impact of total mutans streptococci (MS), total acid tolerant bacteria and Candida species on the development of dental caries in a subset of these children. Of particular interest was the relationship between caries development and co-colonization of mutans streptococci and Candida species. Methods: Children between the ages of 12 and 47 months displaying no evidence of dental caries were recruited for a longitudinal study (n = 130). Twelve age- and gender-matched pairs were selected. In each pair, one child developed caries during the study, and one did not. Whole mouth plaque samples were collected by swab at baseline and every 6 months thereafter for a duration of 18 months and spiral plated for microbial counts (CFU/ml). Cut-offs based on percent of total cultivable flora were designated for all microbial measures. A scoring system designated the Plaque Microbial Index (PMI) was developed for use in statistical analyses to assess potential predictive factors for caries risk assessment. Results: Children who developed caries were significantly more likely to harbor higher percentages of acid tolerant bacteria (p = 0.003), MS (p < 0.001) and have Candida species present (p < 0.001) at ≥1 visit leading up to caries onset. Mean PMI scores derived from the aforementioned microbial measures, were higher for caries active children than caries free children (p = 0.000147). Co-colonization of MS and Candida species was significantly associated with caries development (p < 0.001) and detection of both at the same visit had a 100% positive predictive value and 60% negative predictive value for caries development. Conclusion: In children who developed caries, there was a statistically significant association with the percent of total flora that was acid tolerant, the percent of MS, the presence of Candida and co-colonization of MS and Candida species. Combining these microbial measures into PMI scores further delineated children who developed caries from those who remained caries-free. These microbiological measures show potential as predictive factors and risk assessment tools for caries development.

RESUMEN

OBJECTIVES: To develop a caries-risk assessment application (myRisk app) and assess the psychometric properties based on content validity, construct validity, and how well it classifies the participants into different caries risk groups using caries increments at 10 months. METHODS: The myRisk mobile application was developed using Android Studio 4.1.1. The content validity was assessed by three dental experts. To evaluate construct validity and the prediction of future dental caries, the participants (N = 88) were recruited from Rajvithi Home for Girls in Thailand by convenience sampling. The participants were completed a caries risk assessment (CRA) of myRisk app and ADA form. The oral examination was performed at the time of CRA and 10 months following the baseline. RESULTS: Eighty-eight participants aged 12-29 used the myRisk app and completed the ADA form. The app content validity was acceptable (IOC = 0.67). According to myRisk, 7.9%, 71.6%, and 20.5% of the participants were classified into the low-, moderate-, and high-risk groups, respectively. The percent agreement of the caries-risk classification with the ADA form was 30.7%. Significant differences between the three risk groups were found in active caries (p < 0.001), type, and frequency of sugary snacks (p = 0.002). The app had a sensitivity of 68%, a specificity of 61%, and an area under the receiver operating characterisitic (ROC) curve of 0.61. CONCLUSIONS: The myRisk app has acceptable content validity and sufficient diagnostic accuracy (sensitivity, specificity, and ROC curve). However, there is a different outcome in caries-risk classification compared with the ADA form.

RESUMEN

Dental caries is one of the most common chronic diseases caused by progressive bacteria, affecting all age groups. Today, restorative fillings are widely used for dental caries treatment, but the restorative treatment has a high failure rate. Meanwhile, many researchers have discovered the differences of caries risk among populations by using the caries risk assessment and put forward a new standpoint that caries should be treated individually. Therefore, our research group established a Dental Caries Treatment Difficulty Assessment system in a previous study. This time, we combined the caries risk assessment with the caries treatment difficulty assessment, then used Python to design a Dental Caries Management Software. The purpose of this case report is to present a case applying this software in dental caries management and other data collected in Chengdu, China, with this software on the assessment of caries treatment difficulty. Patients with personalized assessment and management can achieve good treatment results, including reducing the risk and treatment difficulty of dental caries. At the same time, other cases show that the software has good application potential in individual management and group information collection. These cases indicate that the software enables dentists to carry out both the risk assessments and the treatment difficulty assessment of patients, and it has the potential as a tool for epidemiological investigation. It also enables dentists and patients to have a basic understanding of the dental health status of patients and create personalized dental caries treatment, so as to achieve the goal of controlling the progression of dental caries and rebuilding the structure and restoring the function of teeth.

RESUMEN

Background: Limited information is known about dental implementation by pediatric primary care physicians (PCPs) at the primary care level in China. This study aimed to explore the current status of primary oral care implementation and related influencing factors. Methods: A cross-sectional survey was conducted among PCPs in Sichuan Province, China. Multivariable logistic regression was used to analyse factors associated with CRA and dental referral for high caries-risk children. Results: A total of 504 out of 524 questionnaires remained for analysis. In all, 93.8% of PCPs reported that they usually or sometimes performed dental screening for children, 31.3% performed CRA, and 49.0% referred high caries-risk children to dentists. More CRA activities were associated with PCPs who encountered a greater number of children with caries during systematic care (adjusted OR: 2.37, 95% CI:[1.08,5.18], had dental knowledge training by pediatric dentists (aOR: 2.26, 95% CI:[1.36, 3.75], and learned pediatric dental knowledge on their own (aOR: 2.87, 95% CI: [1.51, 5.45]). In addition to the above associators, a higher rate of dental referrals for high caries-risk children was associated with having a dental department in the same work institute (aOR: 1.72, 95% CI: [1.09, 2.70] and having more confidence in their dental knowledge (aOR: 1.29, 95% CI: [1.04, 1.61]). Conclusion: Paediatric PCPs commonly implement dental screening but perform fewer CRAs and dental referrals for high caries-risk children during systematic health management in western China. To increase CRA activities and dental referral by paediatric PCPs, health policymakers could encourage interdisciplinary cooperation between dental professionals and paediatric PCPs.

RESUMEN

BACKGROUND: The purpose of this study was to evaluate the change in intraoral cariogenic bacteria density after probiotic use in patients with orthodontic treatment, and to compare the impact of probiotics in patients with various caries risk status. METHODS: Patients that planned to receive orthodontic treatment were recruited according to this study's inclusion/exclusion criteria. A probiotic prescription (Lactobacteria 3 mg, Glycobacteria 2 mg) was started one month after the initial orthodontic treatment. Saliva sampling and cultures using a CRT kit (caries risk test) were performed at three time points (T0, T1, T2). Mutans streptococci (MS) and Lactobacilli (LB) density were evaluated and scored using the interpretation chart in the CRT kit to evaluate the change in bacteria density at three time points, to define the high and low caries risk prior to orthodontic treatment, and to evaluate if there were differences in probiotics between the high and low caries risk groups. RESULTS: Thirty-three orthodontic patients were enrolled, twenty-two classified as high caries risk and eleven as low caries risk. After undergoing treatment for one month, the densities of MS and LB increased significantly (p = 0.011, p = 0.001); probiotics for one month decreased the density of MS and LB, but the differences were statistically nonsignificant (p = 0.109, p = 0.109). Patients classified as low risk of caries demonstrated an increase in MS and LB density one month after orthodontic treatment (p = 0.024, p = 0.001), probiotic use did not result in a significant reduction in bacteria density (p = 1000, p = 0.933). In patients with high caries risk, there were no statistically significant changes in MS count between the three time points (p = 0.127); a significant change in LB density occurred at T0-T1 (p = 0.011) only. CONCLUSIONS: Supplemental use of probiotic oral tablets during orthodontic treatment aimed at reducing cariogenic bacteria count in saliva did not achieve significant differences, regardless of patients' risk status for caries.
