上颌磨牙龋源性残冠截根术治疗的临床研究

Abstract

Abstract: Objective: To investigate the clinic effect of root amputation of maxillary molar with residual crowns for caries, guiding clinical work. Methods: After informed consent, 30 maxillary molar residual crown resulting from caries were selected. As for every tooth, the amputation of one root or two was performed, and root canal treatment plus periodontal therapy was done. The prognosis was evaluated 3 months and 6 months after the amputation. Result: 6 months later, the amputation of 28 teeth was successful. One tooth failed due to root fracture, and another due to periodontal abscess. Conclusion: Root amputation of maxillary molar residual crown for caries can be effective.

Key words: maxillary molar, residual crown, root amputation
