ABSTRACT

Aim: Teeth extraction is an important problem in elder patients. Although some of these teeth have been endodontically treated, many of them may be subjected to extraction. The reasons for extraction are important for prevention planning in further patients. The aim of this study was to assess the prevalence and important reasons for extraction of endodontically treated teeth in adult Nigerians.

Materials and methods: This study involved a retrospective examination of 2,000 case files in the archives of the University of Nigeria Teaching Hospital. Out of the 2,000 case files, 650 concerned endodontically treated teeth.

Results: The prevalence of extractions in the population was 21.5%. This was more often in the mandible (67.9%) than in the maxilla (32.1%). In both jaws, more molars were extracted (57.1%), followed by premolars (27.1%) and anterior teeth (15.7%). Extractions occurred 57.1% of times in females. However, the rate of extraction decreased with age but peaked in the 51-60 year age band.

Conclusion: The association between age and extraction was proven. Caries, vertical root fracture and endodontic reasons accounted for the commonest cause of extraction in the mandible; while in the maxilla, endodontic reasons and cusp fracture caused extractions most often.

Clinical significance: The reasons for extraction of endodontically treated teeth are different between maxilla and mandible.
