Among surgical procedures in the Pediatric Dentistry Clinic at Nihon University Dental Hospital, extraction of supernumerary teeth has been carried out the most frequently. In this study, we examined the dental records of children who visited our clinic from January 2010 to December 2018, and the records of 630 children who had supernumerary teeth were selected for this survey of children's management during extraction.
The male to female ratio was 2.5 : 1, and most of the children had one supernumerary tooth in the maxillary anterior region. Extraction of an erupted supernumerary tooth was carried out at around 6 years of age in many cases, while extraction of an impacted supernumerary tooth was most often performed at around 6–8 years. As for the method of managing children during extraction of the supernumerary tooth, 41% of the children were treated by the usual method, 34% under general anesthesia, and 25% under intravenous sedation. Among them, extraction of the impacted supernumerary tooth was carried out under general anesthesia in 49%, by the usual method in 37%, and under intravenous sedation in 14% of the affected children.
Binominal logistic regression analysis was carried out to examine the relationship between the degree of cooperation by children (n = 381) and the type of management during extraction, and we found that there was a significant relationship (p＜0.001) between them, indicating that a majority of cooperative children were treated by the usual method while a majority of uncooperative children were not. In contrast, there was no relation between the depth of the supernumerary tooth and the type of management during extraction in 183 children examined.
In conclusion, although both the degree of cooperation and the depth of the supernumerary tooth in children should be considered in determining management methods during extraction, the degree of cooperation by children was revealed to be a chief determinant of this matter in our clinic.
