Total scores and subscale scores of the three clinical groups were compared through ANOVA. Results.  There was no significant difference in mean total scale score and subscale scores between functional and headgear groups (P > 0.05). Significant differences were found in

both mean total and subscale scores between the malocclusion and nonmalocclusion groups (P < 0.001) except oral symptoms subscale (P > 0.05). Conclusions.  The results of this GSK-J4 study reveal that functional and headgear appliances do not differ in terms of impact on daily life during the treatment. Moreover, both groups have poorer OHQoL compared to malocclusion group. “
“Traumatic dental injury (TDI) has been considered a significant problem in youth, not only because ICG-001 purchase of its consequences to the craniofacial structures but also for its potential impact on the quality of life of affected individuals. The aim of this study was to investigate the impact of TDI with treatment needs on the oral health–related quality of life (OHRQoL) of South Brazilian schoolchildren. A cross-sectional study was performed in Porto Alegre, Brazil, using a multistage probability sampling strategy. Of 1837 eligible 12-year-old schoolchildren attending public and private schools,

1528 were examined. OHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11-to 14-year-old children (CPQ11–14) – 16-item short form. Clinical examination was conducted to assess the presence of TDI in permanent incisors (Children’s Dental Health Survey criteria), malocclusion, and dental caries. Parents/legal guardians answered questions on socioeconomic status. Statistical analyses were performed using Poisson regression models. The overall CPQ11–14 score was not associated with TDI. In the functional limitations domain, individuals presenting TDIs with treatment needs experienced significantly higher mean

CPQ11–14 than individuals with no TDI or without treatment needs (RR = 1.21; 95% CI = 1.05–1.39), after adjusting for malocclusion, Palmatine dental caries, gender, and socioeconomic status. No other domains were associated with TDI. This study revealed that TDI with treatment needs negatively affects the OHRQoL in this population of 12-year-old schoolchildren and that this impact is related to oral functions. “
“Toothbrushes harbor a high number of cariogenic microorganisms. To investigate the viability of mutans streptococci (MS) on toothbrushes bristles and the production of extracellular polysaccharide (ECP) related to drying time. Twenty children were submitted to brushing without dentifrice. Toothbrushes were kept at room temperature from 0 to 48 h and then submitted to microbiological processing. The number of MS colonies/biofilms was expressed according to scores: 0 = no colonies were detected; 1 = 1 to 50; 2 = 51 to 100; 3 = over 100.
