Nigerian dentists′ knowledge of aggressive periodontitis

Abstract

Objective: To assess the general knowledge of Nigerian dentists on aggressive periodontitis (AgP) and specific knowledge of distinguishing between the clinical features of localized aggressive periodontitis (LAP) and generalized aggressive periodontitis (GAP). Materials and Methods: A cross-sectional, non-random convenience survey was done on 200 dentists, in three geopolitical zones of Nigeria, using pre-tested, closed question– type questionnaires. Eventually, only 133 questionnaires were analyzed. Relationships between six outcome variables namely clinical features of LAP, clinical features of GAP, LAP oral hygiene, GAP oral hygiene, laser therapy option and type of laser therapy, and the explanatory variables of gender and experience were analyzed. Results: A total of 33.8% of the dentists had poor general knowledge, 16.5% had fair knowledge, 31.9% had good knowledge, while 10.5% had excellent knowledge. Gender- and experience-related differences were found, but they were not statistically signifi cant. Conclusion: Both the general and specifi c knowledge of aggressive periodontitis among Nigerian dentists is less than expected and needs improvement through targeted, continuing dental education.
