A comparison of restoration longevity in maxillary and mandibular teeth
1Department of Oral Diagnosis, School of Dentistry, University of North Carolina, Chapel Hill 27514.
Abstract:
This study determined if the survival time of restorations in maxillary and mandibular teeth differed in a group of 71 patients. The 1,232 restorations were placed by a dental school clinic in a 29-year period. There were no significant systematic differences in the survival time of restorations in maxillary and mandibular molars, premolars, and canines. Maxillary and mandibular incisors show significant differences in survival patterns. Of the mandibular restorations available for follow-up, 71% were still intact after 26 years.
