FARDIN, Angélica Cristiane et al. Fourth molar: the importance of early diagnosis. RFO UPF [online]. 2011, vol.16, n.1, pp. 90-94. ISSN 1413-4012.

Introductions: A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. Its etiology is not fully understood. With regard to its prevalence, it occurs more commonly in permanent dentition and twice as often in men than in women. Supernumerary teeth are classified according to their morphology and location. Their presence can cause problems such as failure of eruption, displacement of teeth, crowding and odontogenic cysts and tumors. The diagnosis is usually by routine radiographs, for the majority of such teeth are impacted and asymptomatic. Objective and Case report: The purpose of this study was to make a brief review of the relevant literature and report one clinical case of the female patient, 23 years, melanoderma, featuring three quarters molars. Final considerations: The early diagnosis proved to be important for the resolution of the case in order to minimize or even prevent the development of complications and thus establish a proper plan of treatment.
