Pattern of endodontic treatment in children in a Nigerian tertiary hospital

The aim of this study was to determine the frequency and reasons for endodontic treatment in patients aged 16 years and below seen at the Paedodontic clinic of the Department of Child Dental Health of the Lagos University Teaching Hospital.

Dental records of patients aged 16 years and below treated for various dental problems at the Paedodontic clinic of the Lagos University Teaching Hospital between January 2006 and December 2007 were reviewed to select cases that received endodontic treatment. The survey was conducted to determine the frequency of endodontic treatment for each tooth in the maxilla and mandible, the reasons for endodontic treatment and type of endodontic treatment performed in each tooth. Data on age, sex, endodontically treated teeth, reasons for endodontic treatment and date of treatment was retrieved from the patients' dental records.

A total of 2376 patients were seen during the period of survey, out of which 260 (11%) patients received endodontic treatment of three hundred teeth comprising 194 mandibular teeth and 106 maxillary teeth. The primary lower second molar (26%) was the most frequently endodontically treated tooth followed by the permanent lower first molar (22%). All the primary and permanent molars were endodontically treated due to caries while 62.5% and 60% of permanent and primary central incisors respectively were endodontically treated due to caries. The other infrequent reasons for endodontic treatment were trauma (5.3%) and failed root canal treatment (1.3%).

The primary lower second molar was the most frequently (26%) treated endodontically and the major reason (93.3%) for endodontic treatment was caries. Only 5.3% of the endodontically treated teeth were due to trauma.
