Coronal tissue loss of endodontically treated permanent teeth of patients seen in a Nigerian Teaching Hospital

Objectives: The study was done to determine the extent of coronal tissue loss of endodontically treated teeth. Results: 176 teeth of 168 patients that completed endodontic treatment to obturation stage were evaluated for coronal tissue loss. The teeth included fifty-five anterior teeth (31.3%), seventy-three premolars (41.5%) and forty-eight molars (27.3%). Majority (43.2%) of the root filled teeth evaluated for coronal damage had minimal coronal tissue damage, followed by teeth with significant tissue damage (33.5%), and lastly, teeth with moderate tissue damage (23.3%). Conclusions: The result of this study revealed that most endodontically treated teeth had minimal coronal tissue loss and therefore can be managed with conservative restorative treatment options.
