PREVALENCE OF IMPACTED MANDIBULAR THIRD MOLAR TEETH

Impaction of third molars is caused by either insufficient maxillofacial skeletal development or a low correlation between maxillofacial skeletal development and third molar maturation leading to a lack of space between the second molar and the ramus (Obimakinde, 2009). Tooth impaction is presently being diagnosed more often than the past fifteen years. When compared with the primitive races, the modern man seems to have a higher incidence of third molar impaction. Theories on the aetiology of impacted third molars are many and varied but there seems to be a consensus on the association between a modern civilised diet and the occurrence of impactions (Olasoji and Odusanya, 2000).
