Temporomandibular disorders (TMDs) are common painful multifactorial conditions affecting the temporomandibular joint (TMJ) and whose treatment depends on the type and symptoms. Initially, it requires pain control, and, for this, drugs, biting plates, occlusal adjustment, physiotherapy or their association are used. Lately, laser phototherapy (LPT) has been used in the treatment of pain of several origins, including TMDs. This study reports the treatment of a selected group of 74 patients treated at the Laser Center of the Federal University of Bahia between 2003 and 2008. Following standard anamneses, clinical and imaging examination and with the diagnosis of any type of TMD, the patients were prepared for LPT. No other intervention was carried out during the treatment. Treatment consisted of three sessions a week for 6 weeks. Prior to irradiation, the patients were asked to score their pain using a visual analog scale (VAS). Lasers of wavelength (lambda)780 nm, lambda790 nm or lambda830 nm and/or lambda660 nm were used at each session (30/40 mW; spot (varphi) approximately 3 mm; mean dose per session 14.2 +/- 6.8 J/cm(2); mean treatment dose of 170 +/- 79.8 J/cm(2)). Of the patients, 80% were female ( approximately 46 years old). At the end of the 12 sessions the patients were again examined, and they scored their pain using the VAS. The results were statistically analyzed and showed that 64% of the patients were asymptomatic or had improved after treatment and that the association of both wavelengths was statistically significant (P = 0.02) in the asymptomatic group. It was concluded that the association of red and infrared (IR) laser light was effective in pain reduction on TMJ disorders of several origins.

This paper discusses dental fluorosis as a relevant public health problem, using a review of epidemiological studies published in the last 10 years on the disease's prevalence, severity, and risk factors. The results suggest that there are already more cases than expected, although few studies refer to major severity. Thus, measures are needed for the prevention and surveillance of dental fluorosis.

OBJECTIVE:To analyze the factors associated with comprehensiveness in oral health care in Centers of Dental Specialists, according to the guiding principles of the Brazilian Oral Health Policy. METHODS:An exploratory cross-sectional study, based on an interview with 611 users of four specialized dental care centers, was performed in the state of Bahia, Northeastern Brazil, in 2008. The dependent variable was described as "comprehensiveness in oral health care", corresponding to having a primary dental care performed before specialized treatment or concomitantly with it. The main covariables referred to the level of coverage of the family health strategy in the city, users' sociodemographic characteristics, and organizational and geographic accessibility to the service, in addition to the type of specialized care required. RESULTS:Residents of the cities where the Family Healthcare Program had a coverage ≥50% were more likely to conclude their dental treatment (PR=2.03, 95% CI: 1.33;3.09), compared to those who lived in places with lower coverage. Individuals who sought endodontic treatment were more likely to receive comprehensive oral health care than users who were seeking other types of specialized care (PR=2.31, 95% CI: 1.67;3.19). Users with better geographic accessibility to specialized services (PR=1.22, 95% CI: 1.03;1.41), with a reference guide from primary care (PR=2.95, 95% CI: 1.82;4.78) and coming from primary health care services (PR=3.13, 95% CI: 1.70;5.77) were more likely to achieve comprehensiveness in oral health care than other users. CONCLUSIONS:Users with better geographic accessibility, lower age and need of endodontic services were more likely to receive comprehensive health care. Implementation of Centers of Dental Specialists in cities where primary healthcare is not adequately structured is not recommended, because secondary health care would meet the free demand and perform basic procedures, thus not fulfi lling the expected principle of comprehensiveness.

This study investigated the prevalence of dental caries and periodontal condition in a population with sickle cell disease (SCD), analyzing some associations with disease severity. The Decayed, Missing and Filled Teeth index (DMFT) and Community Periodontal Index (CPI) were recorded for 99 individuals with SCD and 91 matched controls. Socio‐demographic status, oral health behaviors, and history of clinical severity of SCD were assessed. Statistical comparisons were performed between the group with SCD and the control group, as well as multivariate logistic regression analyses with DMFT index and CPI as the dependent variables. The mean number of decayed teeth was significantly higher in individuals with HbSS. Older age, female gender, and daily smoking were identified as risk factors for higher DMFT, while older age and absence of daily use of dental floss were risk factors for the development of periodontal disease. In conclusion, risk factors known to cause caries and periodontal disease had more influence on oral health than the direct impact of SCD.

This study aimed to analyze the impact of the Family Health Strategy (FHS) on oral health in Northeast Brazil, in 12 municipalities with more than 100 thousand inhabitants. The reference was 20 census tracts, 10 of which in areas with oral health covered by the FHS for at least a year, matched with 10 census tracts without oral health coverage. The total sample included 59,221 individuals. Three possible effects were considered: negative, positive, and absence of effect on the outcomes, based on the prevalence ratio adjusted by Poisson regression. The outcomes "access to collective preventive measures" and "treatment of toothache" indicate a positive effect in the FHS oral health model. However, the outcomes "coverage of tooth extraction" and "restorative treatment" showed either a negative effect or no effect in the majority of the municipalities in the sample. Evidence indicates that within the FHS, the results reflect the local organizational models for oral health care.
