Developmental dental anomalies refer to deviation from the normal size, shape, number or structure of external and internal anatomy of a tooth. Their presence have functional and clinical significance. With no definite reason some dental anomalies may occur commonly in some specific teeth like microdontia in maxillary lateral incisors, dens invaginatus in maxillary lateral incisors, dens evagin...

Abnormalities of tooth shape and size generally coexist, as both are determined during the morphodifferentiation stage of odontogenesis. This report describes a case of lobodontia exhibiting multiple dental anomalies of which, "fang like" cuspids, multituberculism of molars, hypodontia along with severe generalized microdontia are distinctive. Radiographic features, diagnostic convolutions, dif...

BACKGROUND The aim of this study was to investigate the prevalence of tooth agenesis, microdontia, and tooth malformation among non-syndromic oral cleft patients and their potential association with cleft type and gender. METHODS Intraoral records and radiographs of 154 patients (97 males and 57 females) were examined. The variables assessed were tooth agenesis, microdontia, dental malformati...

The published literature on tooth transposition includes only a few studies that have involved more than 50 subjects. The aim of the present study was to investigate the prevalence of true maxillary tooth transposition and possible associated dental anomalies in a larger sample of children. The dental records and radiographs of children who had been diagnosed as having true maxillary tooth tran...
