Abstract: OBJECTIVES: The effect of metal precrown restoration of distal proximal maxillofacial caries in the first deciduous molar on the composite resin filling of mesio-adjacent maxillofacial caries in the second deciduous molar was investigated. METHODS: A total of 80 children aged 4-8 who visited our clinic were selected, and 120 teeth were examined. Two consecutive deciduous molars in one jaw were considered a single case when the distal proximal maxillary surface of the first deciduous molar and the mesial proximal maxillary surface of the second deciduous molar simultaneously had caries. The teeth were randomly divided into two groups: group A (68 cases), in which the first and second molars were repaired with composite resin, and group B (52 cases), in which the first deciduous molar was repaired with metal precrown after composite resin filling and the second deciduous molar was filled with composite resin. The two groups were compared in terms of the success rate of composite resin filling in the second deciduous molar. RESULTS: <0.05) was found between groups A (66.18%) and B (86.54%). CONCLUSIONS: Compared with composite resin filling of the first deciduous molar, the metal precrown restoration of the first deciduous molar can improve the success rate of composite resin filling of the second deciduous molar.
