Primary Canine and Molar Relationships in Centric Occlusion in 3- to 6-year-old Children: A Cross-sectional Survey

Abstract

IntroductionThe occlusal relationship of primary dentition plays a vital role in predicting malocclusion in permanent dentition because primary dentition is the stepping stone for permanent dentition.AimThe aim of the study was to assess the occlusal relationships between the primary canine and the primary molar in the primary dentition in centric occlusion and also spacing in primary dentition among a group of 3- to 6-year-old children.Materials and methodsThe survey was based on examination of the primary dentition of 100 school children aged 3–6 years from Chennai, Tamil Nadu, India. The examination was done using pen light and mouth mirror. The occlusal assessment was done only on children who are healthy and free from extensive caries. The primary molar relationship and the canine relationship were assessed using Foster and Hamilton criteria with the teeth in centric occlusion.ResultsThe study showed that, out of 100 school children, the molar relationship 56% had mesial step followed by 36% with flush terminal relationship and 8% with distal step relationship and out of 100 children, the canine relationship 61% of children had class III relationship followed by 27% class I relationship and 12% class II relationship. And around 54% had spacing out of which, maximum spacing was found only in the upper anteriors.ConclusionThe survey concluded showing that the mesial step primary relationship was more common among 5- to 6-year-old children followed by flush terminal relationship and distal step relationship. The class III primary canine relationship was more common followed by classes I and II. Spacing was found more common in upper anteriors.How to cite this articleKumar D, Gurunathan D.

Analysis of occlusion and its correlation with gender in primary and mixed dentition of pre-school and school children of Hazaribag city – A pilot study

“…In our study, majority of occlusion in population with primary dentition had Mesial Step plane (69.3%) followed by Flush Terminal plane (28.7%) and Distal Step (2%). The results are in accordance with reports of Dilip Kumar et al [4][5][6][7][8] A significant correlation was also noted with gender. Males showed more Mesial Step plane (72.6%) than females (65.6%) and a study by Bhayya DP et al reported similar inference.…”

Occlusal Characteristics of the Primary Dentition Among a Sample of Yemeni Pre-School Children

“…teeth. However, the result was lower than studies conducted in India, Sudan, Iraq, Saudi Arabia, Turkey and Nepal, where the prevalence of class I canine relationship was in the 80-90 percentile 2,16,20,21,29,30,36 .…”

“…Similar findings were seen in studies done by Bahadure et al, 4 Shah et al 23 and Vegesna M, et al, 24 while contradictory findings were reported in Finnish children where class II canine relationship was found to be more common. 24 In contrast, Kumar et al 25 found that class III canine relationship (61%) was more predominant, followed by class I (27%) and class II (12%).…”
