Anquilose da articulação temporomandibular em criança: relato de caso / Ankylosis of temporomandibular joint in child: case report

A anquilose da Articulação Têmporo-Mandibular (ATM) é a fusão entre o côndilo mandibular e a cavidade glenóide, restringindo os movimentos articulares, limitando a mastigação e induzindo a problemas estéticos, nutricionais, psicológicos, sociais, e alterações funcionais que influenciam no crescimento facial, quando acomete pacientes infantis.Objetivo: apresentar um caso clínico de anquilose da ATM em uma criança com hipótese diagnóstica de anquilose fibrosa, intra-articular, unilateral, completa, verdadeira, tipo I de Sawhney, da articulação temporomandibular direita, com retro-láterognatia, com etiologia provavelmente congênita ou idiopática, com limitação da abertura bucal e dificuldade à mastigação, sendo indicada a cirurgia e posteriores tratamentos ortopédico funcional dos maxilares, fisioterapêutico e fonoaudiológico.Conclusão: a anquilose da ATM em crianças de baixa idade pode levar a distúrbios no crescimento. Uma descrição detalhada dos achados clínicos, funcionais e radiográficos é necessária para estabelecer o correto diagnóstico...

Temporomandibular joint ankylosis (TMJ) is the fusion of the mandibular condyle and the glenoid cavity, restricting joint movement, limiting chewing and inducing aesthetic, nutritional, psychological and social problems, and functional changes that influence facial growth, when it affects children.Aim: this paper aims to present a clinical case of TMJ ankylosis in a child with a possible diagnostic of fibrous ankylosis, intra-articular, unilateral, complete, true, type I Sawhney, of the right temporomandibular joint, with retro-laterognatia, probably with congenital or idiopathic etiology, with limitation of mouth opening and chewing difficulties, with indication of surgery and subsequent functional orthopedic treatment of the jaws, physical therapy and speech therapy.Conclusion: an ankylosis of the temporomandibular joint (TMJ) in early childhood may lead to growth disturbances. Detailed descriptions of clinical, functional and radiographic findings are necessary in order to establish a correct diagnosis...

Prevalence of early loss of primary molars in school children in Campina Grande, Brazil

The objective of the present study was to evaluate the prevalence of early loss of primary molars in schoolchildren in the city of Campina Grande, PB, Brazil. A total of 369 children [6-10-year-old; 181 boys and 188 girls] were randomly selected from 12 schools. A calibrated experienced examiner [Kappa = 0.90] performed all clinical examinations under natural light. Yates' chi-square test verified the association of variables and odds ratio. Significance level was set to 5%. The results showed that 24.9% of the sample had loss of primary molars, but no differences were observed between genders [p>0.05]. There was larger loss prevalence among the 9 year-olds [27.2%] and the most commonly missing teeth were the lower primary molars [74.3%]. It can be concluded that the early loss prevalence was high and the lower primary molars were the most commonly missing teeth. It can be concluded that the early loss prevalence was high and the lower primary molars were the most commonly missing teeth
