Relationship between the quality of life and oral health in athletes at a Peruvian university.

A cross-sectional study was carried out to determine the relationship between the quality of life and oral health of athletes (soccer and basketball players) at a private Peruvian university. Eighty-nine athletes were evaluated. Their oral health was assessed using the epidemiologic index relating to decayed, missing, and filled teeth (DMFT), the O'Leary plaque control record, and the Periodontal Screening and Recording (PSR) system. Their quality of life was assessed using the Spanish version of the Oral Health Impact Profile 49 (OHIP-49Sp) self-questionnaire. The resulting data were then analyzed using descriptive (mean and standard deviation) and inferential (Spearman rank order correlation) statistics. The athletes presented a mean (SD) DMFT of 4.46 (3.66): 1.40 decayed teeth, 0.02 missing teeth, and 3.04 filled teeth. The mean (SD) O'Leary index score was 45.78 (22.04). In the PSR evaluation, 32.77% of sextants were assigned code 2, 32.77% were assigned code 1, and 30.33% were assigned code 0. According to the OHIP-49Sp survey, the oral health dimensions with higher scores were functional limitation (7.37), physical pain (8.76), and psychological distress (4.80). The Spearman analysis revealed no statistically significant correlation between oral health and quality of life. Moderate caries risk, poor oral hygiene, and probable gingivitis were found in Peruvian university athletes. However, their quality of life was not compromised by their oral health status.

In vitro comparison of the immediate adhesive strength in dentin of three universal adhesive systems

Objective: to compare the adhesive strength in dentin of three universal adhesive systems in vitro by means of the shear test. materials and methods: seventy-five bovine teeth were selected and cut. dentin was exposed from the buccal surface of the crowns with 220 grit sandpaper, and samples were then inserted in transparent acrylic bases (15x10mm). the samples were randomly divided in 3 groups (n=25): G1-universal adhesive system Scotchbond Universal (3M ESPE-USA); G2- Universal adhesive system Peak Universal Bond (Ultradent); G3-Universal adhesive system Tetric N-Bond (Ivoclar Vivadent). the adhesive procedures were carried out according to the instructions of each manufacturer and the restorative procedures were carried out with micro-cylinders (made of Tygon type tubing 0.79x1.5mm) of the composite resin Filtek Z350XT-A2 (3M ESPE-USA). the samples were incubated at 37ºC (+/-5ºC) for 24 hours. adhesive strength was evaluated in a universal test machine by means of the shear test (0.5mm/min, 500N) and the resulting fracture type was evaluated with a Dinolite digital microscope (x200). the results were analyzed by descriptive statistics (Mean±SD), and inferential statistics by a one-way ANOVA. results: no statistically significant differences were found between the universal adhesive systems evaluated G1 (14.91±4.76), G2 (16.90±4.11) and G3 (17.34±4.04)/(p=0.114). conclusions: the shear test resulted in similar values of immediate adhesive strength of the three universal adhesive systems used.
