Non-third molar related pericoronitis in a sub-urban Nigeria population of children.

BACKGROUND The study will report on the prevalence, clinical presentation, diagnosis, and management of non-third molar related pericoronitis seen in children below the age of 15 years who report at the Pediatric Dental Clinic, Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife over a 4½ year period. MATERIALS AND METHODS This is a prospective study of cases of pericoronitis affecting any tooth exclusive of the third molar diagnosed in the pediatric dentistry out-patient clinic in Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife between January 2008 and June 2012. Pericoronitis was diagnosed using the criteria described by Howe. Information on age, sex, history malaria fever, upper respiratory diseases, tonsillitis, and evidence of immunosuppression were taken. Radiographs were taken in all cases to rule out tooth impaction and information on treatment regimen was also collected. RESULTS The prevalence of non-third molar related pericoronitis was 0.63%. More females (63.6%) were affected. Chronic pericoronitis was the most common presentation (73.3%). No case was reported in the primary dentition and the premolar. No case was associated with tooth impaction and the tooth most affected was the lower right second permanent molar (35.7%). Bilateral presentation was seen in 36.4% patients. Herpetic gingivostomatitis was reported in association with one case. Chronic pericoronitis resolved within 3 days of management with warm saline mouth bath (WSMB) and analgesics, while acute/subacute resolved within 10 days of management with antibiotics, analgesics, and WSMB. CONCLUSIONS The prevalence of non-third molar related pericoronitis is the low. The most prevalence type is chronic pericoronitis affecting the lower right second permanent molar.
