A four-year clinical follow-up of nonvital root resection in maxillary molar teeth.

The aim of the study was to evaluate the success of non-vital root resected maxillary molar teeth over a period of four years. Fourteen root resected maxillary molar teeth were evaluated for mobility and probing depth in the area of root resection. Only one failure was observed over a period of four years follow-up. It was observed that removal of one root neither increase the tooth mobility nor the probing depth in most of the cases. It is concluded that non-vital root resection should be considered before molar extraction, because this treatment can provide good results with long term success, provided appropriate patient selection. This procedure can be practised by general dentists with little effort.
