RESUMO
Summary: Oral tuberculosis is very rare and when present they are usually secondary to pulmonary tuberculosis. Tuberculous lesions of the tongue have become so infrequent that they are virtually a forgotten disease entity and may pose a diagnostic problem. The case reported in this paper emphasizes the importance of including tuberculosis in the differential diagnosis of any chronic oral ulcer. The low number of oral infections by M. tuberculosis could be due to underreporting.
RESUMO
Geminated teeth are the consequences of developmental anomalies leading to the eruption of joined elements. According to the current definitions, gemination occurs when one tooth bud tries to divide, while fusion occurs if two tooth buds unite. This article presents two unique cases of gemination of right primary maxillary central incisors. Authors conclude that geminated teeth in primary dentition have to be carefully analyzed as they may be associated with anomalies in the permanent dentition. Correct diagnosis of the condition implicates in a better prognosis for the patient.
