RESUMEN
Abstract Objective: To identify the prevalence, severity, hypersensitivity, and distribution of Non-carious cervical lesions (NCCL) among university students in Brazil. Material and Methods: 179 participants answered an anamnesis with twenty questions about the presence or absence of habits associated with NCCL. The participants' teeth were evaluated to identify the presence or absence of the lesion, its classification, involved surfaces, severity, hypersensitivity, and tooth wear index. A hypersensitivity test was performed with ice water. Data were analyzed using the chi-square test and simple logistic regression (p<0.01). Results: 179 participants answered an anamnesis with twenty questions about the presence or absence of habits associated with NCCL. The participants' teeth were evaluated to identify the presence or absence of the lesion, its classification, involved surfaces, severity, hypersensitivity, and tooth wear index. A hypersensitivity test was performed with ice water. Data were analyzed using the chi-square test and simple logistic regression (p<0.01). Conclusion: The prevalence of NCCL was 15.1% and abfraction was the most frequent lesion. Premolars were the teeth most affected by non-carious cervical lesions.

OBJECTIVE: To compare effectiveness of counselling program versus counselling program plus jaw exercises to reduce pain and click in patients with temporomandibular joint disc displacement with reduction (DDWR). MATERIALS AND METHODS: Patients were divided into two groups: instructions for temporomandibular disorders (TMD) plus jaw exercises (test, n = 34), only TMD instructions (control, n = 34). Pain was analyzed by palpation (RDC/TMD). It was investigated if the click caused discomfort. Both groups were evaluated at baseline, 24 h, 7 days, and 30 days' post treatment. RESULTS: The click was present in 85.7% (n = 60). In 30-day evaluation, there was a statistically significant difference between groups in the right median temporal muscle (p = 0.041); and there was a statistically significant difference in treatment self-perception (p = 0.002) and click's discomfort (p < 0.001). CONCLUSION: The exercise with recommendations showed better results, resolution of the click, and self-perception of the treatment effectiveness. CLINICAL RELEVANCE: This study presents therapeutic approaches that are easy to perform and that can be monitored remotely. In view of the current stage of the global pandemic, these treatment options become even more valid and useful. CLINICAL TRIAL REGISTER: This clinical trial was registered at Brazilian Clinical Trials Registry (ReBec) under protocol RBR-7t6ycp ( http://www.ensaiosclinicos.gov.br/rg/RBR-7t6ycp/ ), Date of registration: 26/06/2020.

The decision on retaining or prophylactically removing asymptomatic lower third molars is still discussed in the literature. This study aimed to verify the association between asymptomatic lower third molars and local bone conditions through periapical radiographs. Based on sample size calculations, 288 radiographs were required. Dependent variables were alveolar bone crest status and radiolucency between the distal aspect of the third molar crown and the ascending mandibular ramus. Independent variables were sex, age, Pell and Gregory and Winter's classification, angulation and distance between second and third molars, third molar side. Advanced ages (OR 1.15; CI 1.08-1.24; p < 0.001) and greater third molar angulations (OR 1.03; CI 1.01-1.04; p < 0.001) significantly increased the chance of radiographic alterations in the bone crest between second and third molars. Radiolucency distal to third molars was solely impacted by patient's age (OR 1.05; CI 1.01-1.11; p = 0.036). Older patients and lower third molars with greater angulations about adjacent second molar should be evaluated for third molar removal because of the increased chance of alveolar bone crest alterations. Older patients should also be monitored for wider radiolucent pericoronal spaces distal to lower third molars and its consequences.

Background: The implementation of the self-cleaning practice is of fundamental importance for the maintenance of oral health and to remove the human dental biofilm which is considered the main etiological factor for the development of caries and periodontal diseases. Objective: This study aimed to evaluate the use of chewing gum, Rolly Brush® and apples as forms of mechanical control and removal of the dental biofilm in the absence of brushing. Materials and Methods: Eighteen volunteers were submitted to plaque index evaluation after a period of 24 hours of no oral hygiene. Then, they would use one of the methods: chewing gum, Rolly Brush®, apple or tooth brushing, chosen by a draw, for one minute, and then, plaque index was evaluated again. This stage was repeated until all participants were submitted to all selected methods, in periods of 24 hours each. Results: Dental brushing was more effective when compared to each of the other methods applied and there was a statistically significant reduction of dental plaque index after apllying all methods of cleaning in all groups. Conclusion: Chewing gum, Rolly Brush® and apple may be used as auxiliary to dental brushing or when such method is impossible to be performed. Clinicaltrials.gov: number of protocol NCT 03.601.585.

RESUMEN
OBJECTIVE: The aim of this study was to compare the effectiveness of two types of treatment (counselling programme versus counselling programme plus jaw exercises) to improve the quality of life of patients with disc displacement with reduction (DDWR). MATERIALS AND METHODS: Patients were divided into two groups. The test group received guidelines for temporomandibular disorders (TMD) plus jaw exercises for DDWR, and the control group received only guidelines for TMD. The total number of investigated patients was 70, thus 35 per group. The oral health-related quality of life was assessed by the OHIP-14 questionnaire. Both groups were evaluated at the baseline and 30 days post-treatment. RESULTS: In the counselling group, there was statistically significant decrease in pain (P = .015) and social disability (P = .046) subscales. In the counselling plus jaw exercise group, there was statistically significant decrease in all subscales (P < .05). At 30 days follow-up, there was a statically significant difference between the two groups in pain (P = .004), psychological discomfort (P < .001), psychological disability (P < .001) and social disability (P = .029) subscales. CONCLUSION: The counselling programme plus jaw exercise protocol showed greater improvement in oral health-related quality of life than the group performing only the counselling programme in patients with DDWR.

PURPOSE: The teeth positioning may be an important associated factor for the pericoronitis' clinical signs. Our objective was to verify the association between lower third molar position according to the Pell and Gregory classification and clinical variables in patients with pericoronitis. METHODS: Cross-sectional analysis of panoramic radiographs and medical records of patients with pericoronitis. Primary outcomes: pain and oral health-related quality of life (OHRQoL); secondary outcomes: mouth opening, edema/erythema extension, visible plaque index, bleeding on probing index, periodontal pocket probing depth, and distal alveolar bone crest height of the adjacent second molar. RESULTS: The edema/erythema extension was higher in the IIA position compared with the IA position (p = 0.03). Regarding the OHRQoL, the OHIP-14 score was 21.0 (± 9.26, range from 4 to 44). The most scored domain was physical pain (5.24), followed by psychological discomfort (4.43). Third molars in IIA position are associated with worse OHRQoL than IB and IIB positions (p = 0.03). CONCLUSIONS: There was a higher extension of edema/erythema and worse OHRQoL when the third molar was in IIA position. Prophylactic removal of mandibular third molar in position IIA may avoid the onset of mucosal edema/erythema and prevent pericoronitis from promoting impairment of individuals' quality of life.

Abstract Background Currently, different pain scales are used extensively to measure clinical pain, especially in dental practice. Objective This study aims to compare pain scales used in clinical research and dental practice, identifying the easiest to understand by patients with Cervical Dentin Hypersensitivity. Method Seventy-four patients with Cervical Dentin Hypersensitivity were stimulated by a thermic test of the sensitive tooth, followed by application of different pain measurement scales (Visual Analogue Scale, Faces Pain Scales, Numeric Rating Scale, and Verbal Rating Scale) and by a questionnaire to evaluate the patient's perception regarding the ease of understanding scales. The statistic tests used were the Wilcoxon, Spearman correlation, and Chi-Square tests. Results The results founded a strong positive correlation between the scales (r = 0.798 to 0.960 p <0.001). The was easiest scale to understand according to the patients was the Verbal Rating Scale (52.7%). Conclusion The pain measurement scales evaluated provide similar information about pain reported in the Cervical Dentin Hypersensitivity allowing the comparison between studies that used them to measure pain. The affinity of the patient with the pain scale can guide the clinical dental practice in the different levels of health care.

RESUMEN
The aim of the present study was to compare the sensitivity and specificity of pain scales used to assess dentin hypersensitivity (DH). The preferred scale, and toothbrushing habits of participants were also investigated. This cross-sectional study was conducted with students and employees of a Brazilian Federal University who presented DH. The participants answered a questionnaire about their toothbrushing and drinking habits. Hypersensitive and non-sensitive teeth were submitted to tactile and ice stick stimuli. Then, the subjects marked their pain level in the visual analogue (VAS), numeric scale (NS), faces pain scale (FPS) and verbal evaluation scale (VES). DH was also assessed by Schiff scale (SS). The data were analyzed by Wilcoxon and Chi-Square tests, as well as by ROC curve. The mean age of the sample (56 women, 16 men) was 27.8 years. The most prevalent acidic beverage was coffee (36.0%) and the most preferred scale was the NS (47.2%). The pain level was statistically higher in teeth with DH compared to teeth without DH (p < 0.05). The accuracy ranged from 0.729 (SS) to 0.750 (NS). The highest sensitivity value was 81.9% for NS. The SS presented the highest specificity (91%). The visual analog, numerical, verbal evaluation, faces pain, and Schiff scales were accurate for DH diagnosis. The Schiff scale was the preferred scale for DH assessment.

BACKGROUND: The biologic width is defined as the coronal dimension to the alveolar bone that is occupied by healthy gingival tissue. The objective of the present study was to correlate radiographic findings of biologic width invasion with the periodontium status. METHODS: It were included 14 patients with restored teeth with biological width invasion, on the proximal sites, observed clinically and radiographically. 122 proximal sites were evaluated, 61 in the test group (biological width invasion) and 61 in the control group (adequate biological width). Smokers and patients presenting periodontal disease or restorations with contact in eccentric movements, horizontal over-contour or secondary caries were excluded from the sample. The invasion of the biologic width was diagnosed when the distance from the gingival margin of restoration to the bony crest was less than 3 mm. Intrabony defect and bone crest level, as well as, their vertical and horizontal components were radiographically evaluated when present. Plaque index, bleeding on probing, probing depth, gingival recession height, keratinized gingival height and thickness, and clinical attachment level were clinically evaluated. Data were subjected to Spearman's Correlation and Wilcoxon's test. RESULT: The most prevalent tooth with biological width invasion was the first molar. There was a statistically significant correlation between the bone crest (p < 0.001), vertical (p < 0.001) and horizontal (p = 0.001) components. In the test group, there was a statistically significant correlation between bleeding on probing (p < 0.001; r = 0.618) and width of gingival recession (p = 0.030; r = - 0.602) with the intraosseous component; and between keratinized gingival height and bone level (p = 0.037; r = - 0.267). In the control group, there was a correlation between plaque index (p = 0.027; r = - 0.283) with bone level and correlation between keratinized gingival thickness and bone level (p = 0.034; r = - 0.273) and intrabony component (p = 0.042; r = 0.226). CONCLUSION: A statistically significant relationship was found between bleeding on probing and gingival recession in patients who presented intrabony defects due to the invasion of biological width, which may be also related to the thickness of the keratinized gingiva.

OBJECTIVE: This study aimed to identify and compare the self-reported and diagnosed prevalence of dentinal hypersensitivity (DH) in an University population; and to verify accuracy, sensitivity and specificity of DH stimuli tests. MATERIAL AND METHODS: Three hundred and eighty patients (67.2% women and 32.8% men) were assessed by questionnaire, clinical exam, tactile and cold water tests. The intensity of DH was assessed using a visual analogue scale, and a calibrated examiner measured the scores using a caliper. The ICC for intra-examiner was 0.990. Scores above 5 mm were considered sensitive teeth. The association between variables was assessed by Chi-square test. ROC curve analysis determined accuracy, sensitivity and specificity of the tests (p < .05). RESULTS: The mean age of participants was 24.08 years. 158 (41.7%) volunteers self-reported the presence of DH, while, 88.7% of the participants were clinically diagnosed (p = .023). In total, 8958 teeth were evaluated, of those 3367 (37.6%) were diagnosed sensitive. The most prevalent teeth with DH were incisors and premolars. The accuracy of the tests with cold water and tactile were 99%. The sensitivity and specificity for cold water and tactile tests were 99.9%, 99.7%, 99.1% and 87.6%, respectively. CONCLUSION: The self-reported prevalence of DH was significantly lower than that clinically diagnosed. The cold test proved to be a highly accurate stimulus for the diagnosis of DH.

BACKGROUND: This cross-sectional study aimed to identify the factors associated to the cervical dentin hypersensitivity (DH) in Brazilian adult population. METHODS: Three hundred and eighty patients (67.2% women and 32.8% men) were assessed by questionnaire and thermal test with ice. Participants marked in a visual analogue scale (VAS) the intensity of pain, and a calibrated examiner (ICC 0.990) measured the scores using a caliper. Pain scores above 0.5 mm were considered sensitive teeth. The DH associated factors were investigated by clinical examination. The association between variables was assessed by Spearman correlation and the Chi-square test. Logistic regression was used to determine the variables that predict DH (p < 0.05). RESULTS: The mean age of participants was 24.08 years. In this population, 8958 teeth were evaluated, of those 3037 (33.9%) were diagnosed sensitive. The most prevalent associated factors to DH were abnormal tooth positioning (9.0%), occlusal trauma (6.5%) and gingival recession (5.6%). The erosion predicted significantly the DH on both simple (OR 7.85, p < 0.001) and multiple(OR 4.36, p < 0.001) analysis. CONCLUSION: The exposure of dentinal tubules by erosion is probably the major predictor of dentin hypersensitivity. The healthy tooth is able to protect against DH.

OBJECTIVE: Evaluate and compare the isolated and combined effects of Inspiratory Muscle Training (IMT) and Aerobic Training (AT) on respiratory and functional parameters, inflamatory biomarkers, redox status and health-related quality of life (HRQoL) in hemodialysis patients. METHODS: A randomised controlled trial with factorial allocation and intention-to-treat analysis was performed in hemodialysis patients. Volunteers were randomly assigned to performe 8-weeks of IMT at 50% of maximal inspiratory pressure (MIP), low intensity AT or combined training (CT). Before the interventions, all the volunteers went 8-weeks through a control period (without training). Measures are taken at baseline, 8-week (after control period) and 16-week (after the interventions). Primary outcomes were functional capacity (incremental shuttle walk test), MIP and lower limbs strength (Sit-to-Stand test of 30 seconds). Plasma levels of interleukin-6 (IL-6), soluble tumor necrosis factor receptor 1 (sTNFR1) and 2 (sTNFR2), adiponectin, resistin and leptin, redox status parameters and HRQoL (KDQOL-SF questionnaire) were the scondary outcomes. Data analyses were performed by two-way repeated measurements ANOVA. RESULTS: 37 hemodialysis patients aged 48.2 years old (IC95% 43.2-54.7) were randomized. Increase of MIP, functional capacity, lower limbs strength and resistin levels, and reduction of sTNFR2 levels in 16-week, compared to baseline and 8-week, were observed in all the groups (p<0.001). IMT improved functional capacity, MIP and lower limbs strength in 96.7m (IC95% 5.6-189.9), 34.5cmH2O (IC95% 22.4-46.7) and 2.2repetitions (IC95% 1.1-3.2) respectively. Increase in resistin leves and reduction in sTNFR2 leves after IMT was 0.8ng/dL (IC95% 0.5-1.1) and 0.8ng/dL (IC95% 0.3-1.3), respectively, without between-group differences. Compared to baseline and 8-week, adiponectin levels (p<0.001) and fatigue domain of the HRQoL (p<0.05) increased in 16-week only in CT. CONCLUSION: IMT, AT and CT improved functional parameters and modulated inflammatory biomarkers, in addition, IMT provoked a similar response to low intensity AT in hemodialysis patients.

OBJECTIVE: The aim was to evaluate the influence of multiple factors on the periapical status of endodontically treated (ET) teeth. METHODS: The patients were clinically and radiographically reevaluated after root canal therapy. The quality of the root-filled canals, coronal restorations, intraradicular posts, dental caries, and periodontal parameters were associated with the teeth's periapical status. RESULTS: The 122 patients provided 154 ET teeth; 97.4% teeth were asymptomatic, and 75.5% had a normal periapical status. The percentage of perfect, satisfactory, and deficient root-filled canals was of the order of 41.6%, 46.1%, and 12.3%, respectively. The percentage of adequate and inadequate coronal restorations was 31.2% and 68.8%, respectively. A total of 14.9% teeth had intraradicular posts, and 29.2% had cavitated carious lesions in the dentin. Gingival bleeding was observed in 31.8% of teeth, and dental biofilm was visible in 58.4%. A total of 11.7% showed pathologic tooth mobility, and 22.1% teeth were diagnosed with periodontal disease. CONCLUSIONS: Carious lesions, gingival bleeding, and tooth mobility were significantly associated with the occurrence of periapical lesions in root-filled canals.
RESUMEN
OBJECTIVE: Temporomandibular disorder (TMD) is a variety of clinical problems that originate from the area of the temporomandibular joint (TMJ), masticatory muscles, and surrounding tissues. There are different treatment options; however, there is no evidence that low level laser treatment (LLLT) will last about six months. The aim of this study was to determine the survival rate of treatment with red (660 nm) and infrared (790 nm) laser in cases of TMDs. METHODS: In 19 subjects, one side of the face (half face) was randomly selected to receive intervention, in a total of 116 sensitive points. Pain was measured at baseline and time intervals of 24 h, 30, 90, and 180 days after treatment. Laser irradiation with 4 j/cm² in the TMJs and 8 j/cm² in the muscles was used in three sessions. Kaplan-Meier survival analysis and logistic regression were performed. RESULTS: Both treatments showed statistically significant results (p < 0.001). The survival rate for red and infrared laser was 0.24 and 0.30, respectively, at 180 days. Grinding teeth and headache were associated with recurrent pain. DISCUSSION: Both lasers were effective in the treatment of TMD symptoms and had a low survival rate at 180 days.

AIM: The aim of the present study was to assess the periodontal condition and sensitivity of second mandibular molars after the extraction of the adjacent third molar, while also assessing the quality of life of the patients. MATERIALS AND METHODS: Twenty-three healthy patients were assessed in terms of probing depth, gingival height, gingival thickness, dental sensitivity, plaque index and bleeding on probing (adjacent second mandibular molar), before the surgical procedure, as well as 60 and 180 days after the surgery. The following data were also recorded and measured: the position and size of the impacted teeth; the size of the alveoli after surgery and the quality of life of the patient. RESULTS: Significant differences were found for probing depth and gingival height before and after 180 days. The plaque index increased significantly after surgery (P = 0.004), as did bleeding on probing. No significant difference was found for the quality of life. The size of the third molar extracted was correlated with bleeding on probing 180 days after the surgery. CONCLUSION: An improvement was noted in the periodontal condition of the second mandibular molars after the extraction, based on the assessments of probing depth and gingival height. The position of the third molar affected the periodontal condition of the second mandibular molar. No alterations were recorded for dental sensitivity or the quality of life after the extraction.
RESUMEN
OBJECTIVE: The aim of this study was to determine the prevalence of bruxism in students at the Federal University of the Jequitinhonha and Mucuri Valleys in Brazil. The secondary objectives were to identify the factors associated with bruxism; prevalence of dental wear; and to distinguish the signs and symptoms of temporomandibular dysfunction when present, and verify its relationship with bruxism. METHODS: Two hundred fifty-three students (106 males, 147 females) were clinically examined and answered a questionnaire. Trained researchers performed the dental wear evaluation. The incisal edge and occlusal surface were classified as follows: no wear, wear into enamel, wear into dentin, and extensive wear into dentin. Demographic data and factors related to bruxism were obtained by a questionnaire. The participants who presented dental wear and habit of clenching/grinding teeth were classified as bruxers. The data were analyzed by the SPSS program (p < 0.05). RESULTS: The results showed that 31.6% of the students had bruxism. Of the 7084 teeth evaluated, 376 (5.3%) had some type of facet wear. The teeth that had the highest prevalence of wear facets were the canines. Stress, muscle pain, temporomandibular joint (TMJ) pain, and TMJ noise were significantly associated with bruxism (p < 0.001). CONCLUSION: The prevalence of bruxism was 31.6% in this population. The factors most associated with bruxism were stress, muscle pain, TMJ pain, and TMJ noise.

BACKGROUND: The aim of this longitudinal study is to verify changes in the oral health-related quality of life of patients 180 days after treatment of dentin hypersensitivity (DH) with laser and cyanoacrylate. METHODS: This clinical, controlled, randomized, double-masked trial used a split-mouth design, and quadrants were randomized to receive either laser or cyanoacrylate treatments. All patients received both treatments. The study included 62 patients aged 12 to 60 years (mean: 31.4 years) in whom a total of 432 teeth were treated. Quadrants were randomly distributed into two groups: cyanoacrylate (n = 218 teeth) or laser (n = 216 teeth) treatment. DH was evaluated with air and cold stimuli at 24 hours, 30, 90, and 180 days after treatment. The Oral Health Impact Profile (OHIP-14) questionnaire was applied at baseline and 180 days after treatment. RESULTS: There were statistically significant differences in the following OHIP-14 subscales before and after treatment: physical pain (P = 0.002), psychologic discomfort (P <0.001), psychologic disability (P = 0.003), social disability (P = 0.01), and total score (P <0.001). At the end of the study, 80.6% of participants reported an improvement in their condition. CONCLUSION: There was a reduction in the impact of DH on the quality of life of study participants after interventions with laser and cyanoacrylate.
