Clinical Relevance Non-carious cervical lesion restorations using a dual-cure universal adhesive in self-etch and etch-and-rinse mode showed satisfactory clinical performance after 18 months. SUMMARY Objectives: The objective of this multicenter, double-blind, split-mouth randomized clinical trial was to evaluate the clinical performance of a new dual-cure universal adhesive system (Futurabond U, Voco GmBH) when applied using different strategies over a period of 18 months. Methods and Materials: Fifty patients participated in this study. Two hundred non-carious cervical lesions were restored using the adhesive Futurabond U according to four adhesive strategies (n=50 per group): only self-etch (SEE), selective enamel etching + self-etch (SET), etch-and-rinse with dry dentin (ERDry), and etch-and-rinse with wet dentin (ERWet). After the adhesive application, cavities were restored using Admira Fusion composite resin. These restorations were evaluated according to FDI World Dental Federation criteria for the following characteristics: retention/fracture, marginal adaptation, marginal staining, postoperative sensitivity, and caries recurrence. Results: After 18 months, only four patients (12 months: one patient, n=4 restorations; and 18 months: three patients, n=12 restorations) were not evaluated. Fourteen restorations were lost after 18 months of clinical evaluation (four for SEE, three for SET, three for ERDry, and four for ERWet). The retention rates for 18 months (95% confidence interval) were 92% (81%–97%) for SEE, 94% (83%–97%) for SET, 94% (83%–97%) for ERDry, and 92% (81%–97%) for ERWet (p>0.05). Thirty-eight restorations were considered to have minor discrepancies in marginal adaptation at the 18-month recall (13 for SEE, 13 for SET, six for ERDry, and six for ERWet; p>0.05). Fourteen restorations were detected as a minor marginal discoloration at the 18-month recall (six for SEE, six for SET, one for ERDry, and one for ERWet; p>0.05). However, all were considered clinically acceptable. No restorations showed postoperative sensitivity or caries recurrence at the time. Conclusion: The clinical performance of the Futurabond U did not depend on the bonding strategy used, and it was considered reliable after 18 months of clinical evaluation, although more marginal discrepancy was observed in the self-etch group.

Introduction Dental care can improve athletes’ performance, promoting oral health and preventing changes that could disrupt their sports routine. Objective To evaluate the dental conditions, habits, and oral health care of volleyball athletes, and their knowledge of the importance of oral health in sports performance. Methods Sixty-four male athletes participated in the study: 40 from the basic categories (16 ± 3 years) and 24 professionals (25 ± 5 years). For the assessment of oral conditions, changes in the temporomandibular joint, history of facial and dental trauma, and the presence of malocclusions and orthodontic treatment were verified. Hygiene was measured by the visible plaque index. To determine the athletes’ oral hygiene, they were asked how many times per day they brushed their teeth, flossed their teeth, or used oral mouthwash. Finally, we evaluated the athletes’ opinions concerning the importance of oral health and sports performance. Data analysis was performed using the Mann-Whitney and Fisher’s Exact tests, with a significance level of 5%. Results For most of the parameters evaluated, similar results were found between professional and baseline athletes (p> 0.05). However, for the parameters “flossing” (p = 0.0027) and “facial/dental trauma” (p = 0.0444), significant differences were observed (p <0.05) between the categories of athletes. Conclusion We conclude that professional athletes are more prone to facial/dental trauma, and that the presence of a dental surgeon to assist the team improves athletes’ overall oral health. Level of evidence II; Retrospective study.

Aim: In this cross-sectional study, we evaluated the oral hygiene habits, oral health conditions, and the perception about the influence of oral health conditions on the physical performance of youth and professional volleyball and soccer athletes. Methods: A total of 96 male athletes participated: 48 volleyball players (25 youth and 23 professional players); and 48 soccer players, of whom 22 were youth, and 26 were professional players. We analyzed the oral hygiene and oral health condition (daily toothbrush, flossing, mouthwash, dental plaque, orthodontic treatment, dental/facial trauma, temporomandibular dysfunction, malocclusion, and the athletes’ perception about the influence of oral health conditions on the physical performance (yes or no)). Comparisons were made between the youth and professional athletes for each sport (volleyball and soccer). According to each variable, we applied the Chi-square, Fisher’s Exact, and Mann-Whitney tests. Results: For soccer athletes, we found significant differences between youth and professionals for: flossing (p=0.014), orthodontic treatment (p=0.028), dental/facial trauma (p=0.041), and the athletes’ perception about oral health and physical performance (p<0.001). Considering the category (youth and professional) regardless of the type of sport, we found significant differences for dental plaque (p=0.024) and dental/facial trauma (p=0.005). According to the sport (volleyball and soccer), independent of the category, we found significant differences for daily brushing, dental/facial trauma (p=0.005), and the athletes’ perception about oral health and physical performance (p=0.006). Conclusion: We concluded that the surveyed athletes had good oral health and believed that oral health can influence sports performance.
