Occlusion and malocclusion in Lagos

Occlusion among a group of Tanzanian urban schoolchildren

“…However, crowding was more common in the younger age groups than in the oldest one. This contradicts previous results (3,7,10) according to which crowding generally increases with age. Concerning the decreasing tendency of lateral crossbite with age, a similar find-ing has also been reported among Nigerian schoolchildren (3).…”

“…The occlusat and dental disorders recorded in this sample mostly occurred with a normal anteroposterior jaw relationship. The prevalence of crowding (16%) agreed well with the corresponding Nigerian results (15%) (3,4). The same was true of anterior open bite (3.…”

Spacing and crowding among African and Caucasian children

“…With respect to gender, no difference was found for spacing being in agreement with earlier studies (3, 5–7, 14), but in contradiction to other studies on comparable populations where boys had more often spacing in the maxillary and mandibular incisal region than girls had (8, 16, 28). Although in our study no gender difference was found for crowding, being in agreement with other reports (6, 7, 35, 41), in some studies it has been reported to occur more frequently in females than in males (1, 8, 22, 28).…”

“…In Caucasians the prevalence of crowding had a tendency to increase when permanent teeth emerged in the oral cavity, while the pattern in Africans was inconsistent. This agrees with previous reports indicating that crowding is rare in the primary dentition, but increases as dental development proceeds (1, 22, 31). The finding contradicts a previous Tanzanian report (35) according to which crowding was more common in the younger age groups than in the oldest ones.…”

“…Spacing was most prevalent in the primary dentition. In the later emergence stages of the dentition, it was found more frequently in the maxilla than in the mandible in both ethnic groups, being in agreement with earlier reports (14, 22, 26). Generally the prevalence of spacing was almost equally distributed among the two ethnic groups except at ES1 in the maxillary incisal segment and both arches where Caucasian children had more spacing than Africans.…”
