RESUMEN

BACKGROUND: Temporomandibular disorders (TMDs) encompass a spectrum of orofacial conditions characterised by pain and dysfunction in the temporomandibular joint and surrounding structures. Tobacco smoking has been posited as a potential factor influencing the prevalence and intensity of TMD. However, the nature and extent of this relationship remain unclear due to variations in study outcomes. This systematic review aimed to consolidate existing research findings to elucidate the association between tobacco smoking and TMD pain intensity. METHODS: A comprehensive search of electronic databases was conducted to identify relevant studies published up to June 2023. Studies investigating the relationship between tobacco smoking and TMD pain were included. Data extraction was conducted by two reviewers. Quality assessment was performed using the New Castle-Ottawa scale. Review Manager 5.4 was used to quantitatively analyse the results. RESULTS: The review included four studies employing similar TMD assessment techniques. All studies reported elevated TMD pain intensity among tobacco users, with non-smokers exhibiting lower pain intensity. The quality of the included studies was good. Meta-analytic results showed that TMD pain intensity was higher in the smokers group compared to the non-smokers group, with a weighted mean difference (WMD) of 0.65 (BPM) (95% CI: [0.10, 1.19], p = .02). CONCLUSION: This systematic review provides a comprehensive synthesis of the existing literature on tobacco smoking and TMD symptoms. The findings underscore the multifaceted nature of the relationship between smoking and TMD pain, highlighting its clinical relevance and the need for tailored interventions. Further research is warranted to elucidate underlying mechanisms and potential moderating factors, contributing to a more nuanced understanding of this complex association.

RESUMEN

Background: Body goes through significant hormonal and physiological changes during pregnancy, which could be linked to changes in oral health. Many women are unaware of the negative consequences of poor dental health during and after pregnancy, both for themselves and their children. Therefore, this study aimed to assess the effectiveness of Motivational Interviewing (MI) and cross platform messaging application (WhatsApp messenger) for oral health education on the oral health knowledge, attitude and behaviours among pregnant women attending ante natal care. Methods: A randomized controlled trial was conducted among 84 pregnant women. Simple random sampling was employed to select participants after oral examination. Participants were randomly allocated to two groups (Group 1: Cross-platform messaging application [WhatsApp]; Group 2: MI) using a lottery method. Pregnant women aged 18 years and older, gestational age between 8 and 30 weeks were included. A face-to-face interview and oral examination were conducted to assess baseline knowledge and oral hygiene status. A follow-up examination was conducted after one month of intervention. Inferential statistics, including the chi-square test and independent t-test, were used to compare variables between the two groups. Results: The mean knowledge score at baseline was comparable between Group 1 (WhatsApp) and Group 2 (MI). However, post-intervention, Group 2 showed a significantly higher mean knowledge score compared to Group 1. Post-intervention, Group 2 exhibited a significantly better oral hygiene status compared to Group 1. Significant improvements in oral health behaviours were observed in Group 2 compared to Group 1 (p < 0.001). Conclusions: The findings suggested that while both interventions were effective, MI showed superior results in improving knowledge, oral hygiene status, and oral health behaviours. The personalized and client-centred approach of MI enables participants to explore and resolve ambivalence, promoting a deeper understanding of the importance of oral health during pregnancy.

RESUMEN

INTRODUCTION: Oral hygiene is paramount for maintaining optimal oral and physical health, especially among children who are particularly susceptible to dental caries and issues due to dietary habits and inadequate hygiene practices. This study aimed to evaluate the awareness and knowledge of oral health among public school children, analyse their oral hygiene habits, educate parents on the importance of oral health for their children, and implement an oral hygiene educational program in Al-Kharj City, Saudi Arabia. METHODS: Four public elementary schools were selected for the study, with a sample size of 200 school-going children participating. A structured questionnaire was used to assess awareness and knowledge of oral health among the participants. SPSS software version 26 was used for data analysis. Multiple regression analysis and correlation tests was employed to explore the relationships between the different variables measured in the study. RESULTS: The findings revealed a significant lack of awareness regarding oral health among school children. Oral hygiene habits were found to be inadequate in many participants. Overall, the findings highlight the need for targeted interventions aimed at promoting regular dental visits, addressing dental fear, and fostering positive oral hygiene practices among school-going children to improve oral health outcomes in the studied population. CONCLUSION: The study highlighted a critical gap in oral health awareness among school children, underscoring the need for targeted interventions. While the oral hygiene educational program has been implemented and future data will shed light on its effectiveness, preliminary observations suggest that such programs could potentially improve oral health outcomes and overall engagement among students.

RESUMEN

Aim: To compare the sealing ability of three different materials when used as postendodontic restoration barriers to coronal microleakage in root-filled teeth. Materials and Methods: In the present study, 60 single-rooted mandibular premolars with single canals were selected. After endodontic treatment was done with protaper files, they were divided into three groups of 20 teeth each, which were restored with Zirconomer (Group I), Hi-Dense (Group II), and Surefil composite (Group III), respectively. After storing in artificial saliva for 10 days, all teeth were then immersed in Rhodamine 6G fluorescent dye. Teeth were then sectioned buccolingually in a longitudinal direction. The coronal microleakage was measured in both halves under a fluorescence microscope and images were taken with a digital camera. Data obtained from the study in the form of scoring as per specific criteria was subjected to statistical analysis. Result: Results of the study showed that the minimum amount of coronal microleakage was seen in Group II restored with Hi-Dense followed by Group III restored with Surefil Composite and the maximum amount of coronal microleakage was seen in Group I restored with Zirconomer. Conclusion: On the basis of the results of the present study, it may be concluded that Hi-Dense showed better coronal sealing ability in access cavities. Surefil composite exhibited coronal microleakage less than Zirconomer but more than Hi-Dense.

RESUMEN

Lichenoid reactions occur exclusively in people who chew tobacco, areca nut, or both, in raw or any manufactured or processed form. The lesion is described as a lichen-planus-like lesion and is termed as quid-induced lichenoid reaction (QILR). In this cross-sectional study, amongst 935 quid consumers, 82 patients were diagnosed with QILR and it was seen that 65 patients used processed forms of tobacco and areca nut. Thereby, it could be concluded that QILR might occur because of flavors used in processing of tobacco and areca nut.

RESUMEN

BACKGROUND: Clear aligner therapy has gained popularity as a minimally invasive orthodontic treatment option. However, its impact on the masticatory musculature and the stomatognathic system is an area of growing interest, as it involves the adjustment of occlusion and tooth movement. This systematic review aims to comprehensively assess and synthesise existing evidence regarding the influence of clear aligner therapy on the masticatory musculature and the stomatognathic system. METHODS: An exhaustive search was performed on electronic databases that adhered to PRISMA guidelines. Clinical studies that evaluated the impact of patients receiving aligner orthodontic treatment on the muscles of the mastication and stomatognathic systems were included. A standardised data extraction form was devised for relevant variables. Two reviewers extracted the data variables. ROB-2 was used for bias evaluation in the selected studies. RESULTS: A total of six studies met the inclusion criteria. The wearing of clear aligners significantly impacted the muscles of mastication. Muscle activity and discomfort showed a significant alteration in the initial days of appliance placement. but this observation was temporary, with no significant changes thereafter in subsequent follow-up. Bite force reduction was also noted. All the studies evaluated showed good methodological quality. CONCLUSION: The review found that aligned orthodontic treatment may have a variable impact on muscles of mastication, with a potential for initial exacerbation of symptoms followed by possible improvement. However, due to the limited number of studies and their heterogeneous nature, further robust research is recommended to fully understand the relationship between aligned orthodontic treatment and masticatory muscles.

RESUMEN

OBJECTIVE: Studies have shown that non-surgical periodontal therapy (NSPT) helps reduce periodontal inflammation and glycemic levels in patients with type-2 diabetes mellitus; however, the role of NSPT with adjunct photodynamic therapy on glycemic status and periodontal parameters in prediabetic patients remains unclear. The aim of the present study was to assess the effect of NSPT with and without adjunct PDT on periodontal and glycemic statuses in prediabetic patients with periodontal disease. METHODS: Prediabetic (Group-1) and non-diabetic (Group-2) patients diagnosed with periodontal inflammation were included. In both groups, patients were randomly assigned to test and control-groups. In the test- and control groups, patients underwent NSPT with and without adjunct PDT, respectively. The following parameters were assessed at baseline and at four weeks' follow-up: plaque index (PI); gingival index (GI), probing depth (PD), clinical attachment loss (CAL) and hemoglobin A1c (HbA1c). Collection of demographic data and assessment of full mouth marginal bone loss was performed at baseline. Level of significance was set at P < 0.05. RESULTS: At baseline, there was no difference in PI, GI and PD among patients with and without prediabetes. At 3-weeks' follow up there was no difference in PI, GI and PD among patients without prediabetes. PI (P < 0.01), GI (P < 0.01) and PD (P < 0.01) were significantly higher in the control-group compared with the test-group at 3-weeks' follow-up in patients without prediabetes. The HbA1c levels were significantly higher in patients with prediabetes throughout the study duration compared with individuals without prediabetes. CONCLUSION: One session of NSPT with or without PDT reduce periodontal inflammation but do not influence glycemic levels in prediabetic patients.
