Injuries to the Stomatognathic System in Brazilian Jiu-Jitsu Athletes.

As a contact sport, Brazilian jiu-jitsu requires the fighter to expose his/her stomatognathic system to the adversary, making him/her more susceptible to oral and maxillofacial injuries and disorders. The aim of the present study was to determine the prevalence of injuries and disorders of the stomatognathic system and associated factors among practitioners of Brazilian jiu-jitsu. A total of 179 athletes were interviewed and submitted to a physical examination. The majority was male, in the beginner category and had participated in competitions. Athletes with more experience had a higher frequency of orofacial injuries (PR = 1.77; 95% CI: 1.01-1.38), such as oral mucous lacerations and skin abrasions in the facial region, which mainly occurred during training sessions. A mouthguard is not mandatory for the sport and many athletes (both beginners and more experienced athletes) do not use one due to difficulty breathing with the device. A prefabricated (type II) mouthguard was the most common among the athletes who used this equipment, although it does not offer adequate protection. Athletes on more advanced levels wore mouthguards significantly more often (PR = 1.96; 95% CI: 1.11-2.45). In conclusion, more experienced jiu-jitsu athletes had a higher frequency of orofacial injuries, such as lacerations and abrasions, and are more likely to wear a mouthguard. However, longitudinal studies are needed in order to assess the possible causes and risks.

Epidemiological profile of individuals with American cutaneous leishmaniasis in Jequitinhonha Valley, Brazil.

This study aimed to characterize the epidemiological profile of patients with American cutaneous leishmaniasis (ACL) in 34 municipalities in Jequitinhonha Valley, Minas Gerais, Brazil, registered from 2005 to 2010 with the Regional Health Superintendence, using data from the Brazilian Disease Notification Information System. Among 281 cases, 156 (55.5%) were included in the study. A statistically significant difference was found in ACL among men between 21 and 60 years of age (P = 0.034) in relation to women and other age groups. Analysing the male sample, a significant association was found between ACL and occupation (P = 0.04). The cutaneous form occurred in 87.3% of cases. The medication most often employed was pentavalent antimony (87.3%), with cure achieved in 91.1% of cases. The epidemiological profile of ACL in the Jequitinhonha Valley is similar to that reported for other regions of Brazil, exhibiting a rural occupational nature and affecting men with low levels of schooling within the productive age.

Among 281 cases, 156 [55.5%] were included in the study.

Case report: Clinical, histological and ultrastructural characterization of type II dentinogenesis imperfecta.

BACKGROUND: Type II dentinogenesis imperfecta (DGIII) is an autosomal dominant dental development anomaly that affects both the primary and permanent dentition. CASE REPORT: This case report describes the clinical, radiographic and morphological characteristics of the teeth of a seven-year-old child with DGI-II determined by optical microscopy and scanning electron microscopy. TREATMENT: This consisted of extraction of the primary teeth with periapical lesions due to the advanced state of tooth resorption. Aesthetic restorations were performed on the mandibular anterior teeth and occlusal fissure sealants were applied to erupting teeth. A removable partial upper denture was made in order to return anterior aesthetic function and to aid mastication and speech. FOLLOW UP: The child was examined at 3 month intervals. Over the following 3 years the prosthesis was replaced due to facial growth and fluoride was applied at each follow-up visit to all teeth. The patient remains in follow up and management. CONCLUSION: Individuals with DGI-II must not neglect their dental health. Early diagnosis, professional advice and treatment with periodic follow-up can help improve the quality of life of such patients.
