Indications for the removal of impacted mandible third molars at Ibadan--any compliance with established guidelines?

The removal of impacted lower third molars has been a subject of controversy among dental practitioners since the turn of the twentieth century. A yet unresolved aspect of the controversy is the definition of appropriate indications for surgical extraction. Clinical guidelines have long been established but the effectiveness of adoption of the guidelines is still to be proved in our environment. A retrospective observational study of the indications for extractions in oral surgery clinic of the University College Hospital (UCH), Ibadan was conducted with the aim of identifying the common indications and to verify the level of compliance with established guidelines. There were 294 extractions out of which the indications for 268 cases were recorded. We found that pericoronitis constituted the most frequent indication 190 (33.6%) recurrent, 36 (13.4%) acute cases] while apical periodontitis 70, (26.1%) was next most frequent. Prophylactic extractions were performed in 34 (12.7%) cases. Other indications such as pulpitis 19, (7.1%), dental caries 13, (4.9%), dentoalveolar abscess (4, 1.5%), orthodontic reason (1, 0.3%) and tooth fracture (1, 0.37%) were also recorded. Compliance rate with NIH criteria and NICE guidelines were 87.3% and 73.9% respectively. We recommend that prophylactic extractions be discouraged while guidelines should be adequately emphasized for effective clinical practice.
