Relationship between Risk Behavior for Eating Disorders and Dental Caries and Dental Erosion

The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries (p = 0.329; OR = 2.2, 95% CI: 0.35–13.72) or dental erosion (p = 0.590; OR = 2.33; 95% CI: 0.56–9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition (p = 0.031; OR = 5.1; 95% CI: 1.61–23.07). Therefore, high severity risk behavior for EDs was not significantly associated with dental caries and dental erosion. However, high BMI was a risk factor for developing eating disorders and should be an alert for individuals with this condition.

Endodontic treatment associated with photodynamic therapy: Case report.

BACKGROUND DATA The complete elimination of bacteria inside the root canal is a difficult task, and inconsistent removal of the innermost layer of contaminated dentin leaves bacteria behind. PDT is an adjunct to conventional endodontic treatment due to its potential to reduce bacteria and its biocompatibility. OBJECTIVE Report a case of endodontic treatment associated with Photodynamic Therapy (PDT). STUDY DESIGN/PATIENT AND METHODS A patient with chronic dentoalveolar abscess with radiolucent lesion next to the apexes of teeth 11 and 21 was submitted to conventional endodontic treatment associated with PDT. The canals were filled after two PDT sessions with an interval of 15days between applications. RESULTS After six months, total regression of apical periodontitis and no fistula or associated symptoms were observed. CONCLUSIONS The treatment proposed is a viable option for the clinician as it is easy to perform, has relatively low-cost and allows the improvement of symptoms in a short period of time.

Cariogenic and Erosive Potential of Industrialized Cashew Juice

Objective : To evaluate the cariogenic and erosive potential of industrialized cashew juice. Methods: Twenty-seven cashew juice samples of three different brands (n = 9) were analyzed for the following physicochemical parameters: pH, titratable acidity (TA), ascorbic acid, total soluble solids (TSS), TSS/TA ratio and reducing, non-reducing and total sugars. Assays were performed in triplicate and data were processed using ANOVA and Tukey test, considering α = 5%. Results: All samples showed pH values below 5.5, highlighting Da Fruta® brand, with mean value of 3.6 (p 0.05), there was no difference among groups for the amount of ascorbic acid (19.41 ± 3.46 g / 100 mL, p> 0.05), and TSS / TA ratio (35.05 ± 7.10, p> 0.05). Carrefour juices showed higher amounts of TSS (12.52 ± 0.31 g / 100 mL). For reducing, non-reducing and total sugars, mean values of 9.31 ± 0.97, 1.28 ± 1.01 and 10.59 ± 1.73 g / 100 mL, respectively, were found, with no differences among groups (p > 0.05).

Head and face injuries were observed in 10.0% of patients, while maxillofacial and oral cavity injuries were present in 21.7% and 6.7%, respectively. There was an association between occurrence of accident and face injuries (p = 0.009). CONCLUSION: Traffic accidents affect mostly young male individuals, causing multiple injuries in different body areas, including maxillofacial and oral cavity injuries.

Evaluation of Fluoride Release, pH and Microhardness of Glass Ionomer Cements

Objective: To evaluate fluoride release, pH and microhardness of glass ionomer cements (GIC). Material and Methods: Four different cements: Vidrion ® R (G1), Vitro Fil ® (G2), Maxxion ® (G3) and Magic Glass ® (G4) and a composite resin (G5 - control group) comprised the sample. Thirty specimens were manufactured (10 mm x 3 mm) and stored in deionized water. Analyses were performed after 24 hours, 7 days and 28 days. The following devices were used for measurements: fluorometer, pH meter and microhardness tester. Data were analyzed by Kruskal-Wallis, Mann-Whitney, Friedman and Wilcoxon tests (α = 0.05) using the SPSS ® software (Statistical Package for Social Sciences) version 17. Results: GICs were able to release fluoride; however, the amount released decreased with increasing immersion time (p <0.002). The pH of all products increased over time, the lowest value was identified for Magic Glass (5.93) and the highest for Maxxion (6.94) at time of 24 h. Materials showed significant decrease in surface microhardness, especially G4 for presenting the lowest recorded values (p <0.05). Conclusion: GICs are fluoride-releasing restorative materials with pH favorable to oral homeostasis and good mechanical behavior.
