Aim: To categorize the endodontically treated teeth according to the extent of coronal tissue loss in order to determine the appropriate restoration required.
Material and methods: A two year descriptive study was done at the Conservative Clinic of the Department of Restorative Dentistry, Dental Centre, University College Hospital, Ibadan. Successful endodontically treated teeth were assessed and categorized according to the extent of tissue loss based on standard criteria proposed by Smith and Schuman.
Results: Two hundred and ninety endodontically treated teeth were assessed for success both clinically and radiographically. Eighty (27.6%) were anterior teeth, 78 (26.9%) were premolars while 132 (45.5%) were molars. Dental caries was found to be the most common (61.4%) indication for endodontic treatment and caused more coronal tissue damage (moderate and significant) when compared with other indications for endodontic treatment. Two hundred and twenty seven (78.3%) endodontically treated teeth had moderate coronal tissue loss, 41 (14.1%) had minimal damage while 22 (7.6%) had significant tissue damage. Dental caries was the most common indication for endodontic treatment of the posterior teeth while trauma was the most common indication for the anterior teeth.
Conclusion: Majority of the endodontically treated teeth that were evaluated for tissue loss had moderate coronal tissue damage. It is therefore recommended that proper and prompt evaluation of the remaining coronal tooth tissue following successful endodontic treatment be carried out in order to determine the appropriate definitive restoration required that will be easy for the clinician and less expensive to the patients.
Keywords: Spectrum, endodontics, tissue loss, categorization
Résumé
Objectif: Catégoriser le traitement des dents de façon endodontique selon l’importance de la perte de tissu coronaire afin de déterminer la restauration appropriée requise.
Méthodes: Une étude descriptive de deux ans a été effectué à la ‘Conservative Clinic’ du Département de la Dentisterie Restauratrice, Centre de soins dentaire, Centre Hospitalier d’Ibadan. Les dents traités avec succès de façon endodontique ont été évaluées et catégorisées selon l’importance de la perte de tissu sur la base de critère standard proposé par Smith et Schuman.
Résultats: Deux cent quatre-vingt-dix dents traitées de façon endodontique ont été évalué pour déterminer la réussite de façon clinique de même que radiographique. Quatre-vingts (27,6%) étaient des dents antérieures, 78 (26,9%) étaient des prémolaires tandis que 132 (45,5%) étaient des molaires. Les caries dentaires se sont révélées comme étant l’indication la plus commune (61,4%) du traitement endodontique et provoquant plus de lésions du tissu coronaire (modéré et important) en comparaison aux autres indications de traitement endodontique. Deux cent vingt sept (78,3%) dents traitées de façon endodontique avaient une perte de tissu coronaire modéré, 41 (14,1%) avaient des lésions minimales tandis que 22 (7,6%) avaient des lésions importantes du tissu. La carie dentaire était l’indication la plus commune dans le traitement endodontique pour les dents postérieures tandis que le traumatisme s’avérait l’indication la plus commune pour les dents antérieures.
Conclusion: La majorité des dents traitées de façon endodontique qui ont été examinées pour les pertes de tissu avait des tissus coronaires modérés. Par conséquent, il faut une évaluation appropriée et prompte du tissue dentaire coronaire restant à la suite d’un traitement endodontique réussi afin de déterminer la restauration définitive appropriée requise qui va être facile pour le clinicien et moins cher pour les malades.
