PATTERN OF DENTAL OCCLUSION IN A POPULATION OF URHOBO SUBJECTS IN ABRAKA, NIGERIA

Abstract

The closing order of superior and inferior teeth whilst chewing or at relaxation is termed dental occlusion. Literature exploration divulged want of information on dental occlusion among the Urhobos in Delta State, Nigeria. The endeavour of this work was to consider varied dental occlusion patterns and explore gender variation in dental occlusion patterns amongst the Urhobo tribal cluster in Abraka, Nigeria. Totality of 384 citizens (200 females and 184 males) who were within 15-30 years age set were engaged in this inquisition. The gender gap is a depiction of the male/female scattering in the appraised populace. Records on dental occlusion patterns were composed by having the subjects’ bite, gulp saliva, occlude and open their mouths.  The connexion of the upper and lower teeth was labelled as mild overbite, edge to edge bite, negative bite or severe overbite as specified by Eveleth in 1972.  Inferential statistics were explored using chi-square by means of Statistical Package for the Social Sciences (SPSS), version 23 and significance level were determined by p < .05. The dental occlusion patterns observed were mild overbite 168 (43.4%), edge-edge bite 146 (38.2%), severe overbite 70 (18.4%) with no negative overbite 0 (0%). The gender dissimilarity in dental occlusion pattern was not notable (p>.05). Mild overbite is preponderant and severe overbite is infrequent amid the Urhobos in Abraka, Nigeria.
