ABSTRACT
A relação entre a Ortodontia e as disfunções temporomandibulares vem gerando muitas dúvidas e discussões dentro da classe ortodôntica nos últimos tempos. Ao analisar algumas publicações, observa-se que o tratamento ortodôntico tem sido contestado sobre vários aspectos com relação à sua atuação. Se para alguns autores a mecânica ortodôntica pode levar à cura da DTM, para outros, ela pode funcionar como fator etiológico das disfunções do sistema estomatognático. Com o intuito de sanar essas dúvidas, esta revisão da literatura foi realizada, porém, é visível a necessidade de mais pesquisas sobre esse assunto, uma vez que se mostra um tanto quanto controverso.
The relationship between orthodontic treatment and temporomandibular joint disfunction has been subjected to many questions and discussions within in orthodontic community for in the last years. The analysis of recent publication leads to the observation that orthodontic treatment has been in many ways refuted based on its course of action. While for some researchers, orthodontic treatment can lead to TMD cure, for others it can work as the etiologic factor. Aiming to shed some light in this topic, a literature review was performed. However, more studies are necessary since this question has brought some controversy.

Nowadays, esthetics has guided patients to seek for dental treatment. Tooth development anomalies are an important category of morphologic variations and malocclusions. Tooth agenesis, also described as congenital absence, is characterized by numeric tooth reduction. It is one of the most frequent changes in the human being and originates from disturbances at tooth formation initiation and proliferation, being classified as hipodontia, oligodontia, or anodontia. On the other hand, microdontia is characterized by smaller teeth, involving the entire arch or a tooth group. Conoid or microteeth compromise the smile and lead patients to seek for dental treatment. Microdontia can be seen as a series of histological changes at the epithelial tooth structure during enamel organ formation, with the final tooth smaller than the normal values. As dental professionals, we must guide patients for better treatment ways. This paper aimed to present a clinical case involving multiple tooth agenesis and microdontia, highlightening the etiology, prevalence, and treatment of these anomalies.
