Relationship of bruxism with oral health-related quality of life and facial muscle pain in dentate individuals

To determine whether there is a correlation of bruxism (sleep, daytime, or both) with oral health-related quality of life and facial pain of muscular origin in dentate individuals. Seventy-four dentate patients (complete dentition) were included in thi

In vivo comparative study of the effects of using the enamel matrix derivative and/or photobiomodulation on the repair of bone defects

The repair of bone defects has been the subject of many studies that have shown inconclusive results as to what is the best bone substitute. Bone defects (Ø 2 mm) were induced on the tibia of seventy-two rats, which were distributed into the following

Relationship of excessive daytime sleepiness with bruxism, depression, anxiety, stress, and sex in odontology students: a cross sectional study

To verify if there is a correlation of excessive daytime sleepiness (EDS) with bruxism, depression, anxiety, stress, and sex in odontology students. Four hundred dental students were selected. Students included in the study were those that were healthy

Chewing in temporomandibular disorder patients: an exploratory study of an association with some psychological variables

Aims: To compare kinematic parameters (ie, amplitude, velocity, cycle frequency) of chewing and pain characteristics in a group of female myofascial temporomandibular disorder (TMD) patients with an age-matched control female group, and to study correlations between psychological variables and kinematic variables of chewing. Methods: Twenty-nine female participants were recruited. All participants were categorized according to the Research Diagnostic Criteria for TMD (RDC/TMD) into control (n = 14, mean age 28.9 years, SD 5.0 years) or TMD (n = 15, mean age 31.3 years, SD 10.7) groups. Jaw movements were recorded during free gum chewing and chewing standardized for timing. Patients completed the Depression, Anxiety, and Stress Scales (DASS-42), the Pain Catastrophizing Scale (PCS), the Fear of Pain Questionnaire-III (FPQ-III), and the Pain Self-Efficacy Questionnaire (PSEQ). Statistical analyses involved evaluation for group differences, and correlations between kinematic variables and psychological questionnaire scores (eg, depression, anxiety, stress) and pain intensity ratings. Results: Velocity and amplitude of standardized (but not free) chewing were significantly greater (P < .05) in the TMD group than the control group. There were significant (P < .05) positive correlations between pain intensity ratings and velocity and amplitude of standardized chewing but not free chewing. There were significant (P < .05) positive correlations between depression and jaw amplitude and stress and jaw velocity for standardized but not free chewing. Conclusion: This exploratory study has provided data suggesting that psychological factors, manifesting in depression and stress, play a role in influencing the association between pain and motor activity.

Antibiotics plus probiotic as an adjunct to the treatment of periodontitis in smokers: a short-term study

Aim: The purpose of this study was to perform a short-term evaluation of the effects of a probiotic, associated with the use of antibiotics as an adjuvant treatment of periodontitis in smokers. Materials and Methods: Thirty-four patients were randomly divided into: PRO group (n = 17), patients received a single session of scaling and root planing (SRP) associated with the systemic administration of Lactobacillus reuteri tablets; ANT+PRO group (n=17), patients received a single session of SRP followed by the systemic administration of Amoxicillin and Metronidazole 3x/day for 7 days and administration of Lactobacillus reuteri seven days after conclusion of antibiotic therapy. Clinical periodontal parameters were evaluated. Results: After treatment, both groups showed a reduction in BOP, PI, and residual pockets compared to baseline, while in the ANT+PRO group there was a significant reduction in PD and CAL gain (p5mm was observed in the ANT+PRO group (p<0.05). Conclusion: Both adjuvant treatments reduced the residual pockets and controlled inflammation after treatment. Only the association of antibiotic with probiotic therapy was able to efficiently reduce mean PD, the number of pockets with PD >5 mm, and promote additional CAL gains in a short-term evaluation period

Noncarious Cervical Lesions and Their Association With Toothbrushing Practices: In Vivo Evaluation

Objectives: This pilot study aims to investigate the prevalence of noncarious cervical lesions (NCCLs) in a student population at the Faculty of Dentistry of Aracatuba-UNESP and to assess the potential relation between buccal hygiene habits and the presence and number of NCCLs.Methods: This study was conducted with a sample of 58 young volunteers (15 men and 43 women; mean age, 23.6 +/- 1.8 years and 22.3 +/- 2.4 years, respectively). The research was divided into three steps: 1) clinical assessment; 2) oral-hygiene practices self-report questionnaire; and 3) analysis of toothbrush filament deformations. After the clinical exam the participants were divided into two groups, a control group (without NCCLs) and a test group (NCCLs), according to NCCL presence. The data were statistically analyzed with SPSS 16.0 software, using t-test, chi(2), Fisher exact test, and Spearman correlation.Results: NCCLs were present in 53% of the subjects. The presence of NCCLs was marginally statistically associated with age (p=0.15) and proportionally more prevalent in male (80%) subjects (p=0.01). NCCLs were more concentrated in the posterior-superior quadrant (93%) in both the right (90%) and left (55%) sides of the mouth. The direct rank correlation was presented between presence of NCCLs and toothbrush firmness; and between number of NCCLs and age and force applied during toothbrushing.Conclusion: Within the limitations of this pilot study, the use of medium and hard toothbrushes and greater force applied during toothbrushing might contribute to the development and/or aggravation of NCCLs
