Dental anomalies in the deciduous dentition
Importance of early diagnosis
Castanho, Joana / Ramos, Rita / Coelho, Ana / Marques, Paula
Dental anomalies are related to changes in number, size, eruption, morphology or development of the teeth. Most occur between the sixth and eighth week of gestation, when the enamel, dentine and cement begin histodifferentiation.
They may be associated with hereditary, local, systemic or traumatic factors and arise in the deciduous and / or permanent dentition.
Fusion is a developmental anomaly resulting from the union of one or more adjacent teeth during their formation. Any tooth may be affected and it can also involve supernumerary.
This poster aims to illustrate the importance of early diagnosis of dental anomalies, through the description of two clinical cases followed in the university clinic of FMDUL.
Clinical case 1 - Healthy 5-year-old child, who presented a fusion of the tooth 62 with a supernumerary. A small carious lesion involving the entire fusion fissure, in the palatal face was observed. Early diagnosis allowed for a conservative composite restoration. Clinical control was maintained regularly until exfoliation, which occurred at the expected age, in a symmetrical way with the contralateral.
Clinical case 2 - Healthy 4-year-old child, with a fusion between tooth 61 and a supernumerary. Contrary to the previous case, the teeth presented extensive carious lesions, with pulp involvement. The non-restorability and difficulty inherent to pulpal treatment led to the decision to extract the teeth.
These cases demonstrate the importance of the early diagnosis of dental anomalies, in order to allow a preventive or less invasive approach.
