Occlusal Traits of Primary Dentition among Children Visiting a Dental Hospital in Kathmandu, Nepal

Abstract

Occlusion in deciduous dentition varies among children of different populations and races. Paucity of information in Nepalese literature provided the motive for this study. The objective of this study was to examine the occlusal traits of Primary Dentition among children aged 2-6 year old. A cross-sectional study comprising total of 307 children all having deciduous teeth were included in the study. The dentition was examined using a mouth mirror and explorer under illuminated light in Department of Pedodontics and the data was recorded. All the children were screened for molar and canine relationship, overjet, overbite, spaced and non-spaced dentition. Out of the total, Mesial step terminal plane (62%-left; 58%-right), Flush terminal (33%-left; 36% -right) and Distal step (5%-left; 6%-right) were seen. Most of the children had class I canine relation (83%-left; 84%-right), ideal overjet (68.4%), overbite (63.1%) and spaced dentition. Statistical significant difference was found among the gender with respect to overjet. Presence of spacing was more in maxilla than in mandible which was statistically significant. These findings suggested desirable occlusal characteristics and spacing in primary dentition. However, future longitudinal studies are required to examine whether the transition of these occlusal characteristics will lead to favorable outcome in permanent dentition.

Occlusal characteristics including spacing among preschool children: a cross-sectional study

“…This study showed Class I canine relationship to be the most common in more than half of the children while the least common was the class III canine relationship among 19% children. Similar findings was seen in studies conducted by Bahadure et al 12 , Shah et al 6 and Vegesna et al 3 while contradictory findings were reported in Finnish children where class II canine relationship was found to be more common. 13 In this study majority 77% of the children had ideal overjet ,increased overjet was found among 17.4% while 5.6 % had reverse overjet which were in agreement to studies done by Oteyumi et al 10 , Shah et al 6 .…”

“…In addition, Otuyemi et al 10 also reported majority of Nigerian children with flush terminal relationship (74.5%). In contrast to studies done in same population by Shah et al 6 where mesial step molar relationship was seen in more than half of the studied population. Baral et al 11 also found mesial step molar relationship to be common in his studied population in Kaski district of Nepal.…”

“…As seen in the study, Ideal overbite was seen among majority (78%) of the children, various studies showed similar findings. 3,6 Only four (0.9%) children in the study had anterior openbite as reported in other study done in Tanzanian and Finnish children (8%). 14 The study has few limitations as data could have included specific sides, and in detail findings as per arch wise, gender wise for spacing.…”
