  • Occlusion characteristics of preschoolers in Chennai: a cross-sectional study.
    Journal of dentistry for children (Chicago Ill.), 2013
    Co-Authors: X L Anitha, Sharath Asokan
    Abstract:

    PURPOSE The purpose of this study was to assess occlusion characteristics of preschool children in Chennai, Tamil Nadu, India, and assess gender differences of various features of the primary dentition occlusion. METHODS Various occlusion characteristics, such as primary molar Relationship, type of spacing in the primary dentition (open or closed), and presence of malocclusion, were evaluated. Data was analyzed using Pearson's chi-square test. RESULTS A total of 1,836 3- to 6-year old children participated. Flush Terminal plane was the most commonly seen type of primary molar relation (41%). There was no significant difference between genders in relation to primary molar Relationships. Open spacing was more common in the maxilla and in males. There was a statistically significant difference between the type of spacing in the primary dentition (open or closed) and flush Terminal Relationship. Anterior crossbite was seen in approximately 2% of the children, posterior crossbite in 1%, and anterior open bite in 3%. CONCLUSION There was as a low prevalence of asymmetric molar Relationship, distal step molar Relationship and malocclusions such as anterior crossbite, posterior crossbite and anterior open bite in preschool children in Chennai.

  • Primary Canine and Molar Relationships in Centric Occlusion in 3- to 6-year-old Children: A Cross-sectional Survey.
    International journal of clinical pediatric dentistry, 2019
    Co-Authors: Dilip Kumar, Deepa Gurunathan
    Abstract:

    Introduction The 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. Aim The 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 methods The 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. Results The 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. Conclusion The 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 article Kumar D, Gurunathan D.

  • Association of infantile bruxism and the Terminal Relationships of the primary second molars
    Brazilian oral research, 2013
    Co-Authors: Tatiana Helena Junqueira, Ana Carla Raphaelli Nahás-scocate, Karyna Martins Do Valle-corotti, Ana Cláudia De Castro Ferreira Conti, Shirley Trevisan
    Abstract:

    The aim of this study was to analyze the association between infantile bruxism and the Terminal Relationships of the primary second molars. A total of 937 pre-school children (both genders), aged from 2 to 6 years, from municipal schools in Sao Paulo were evaluated. In this study, a questionnaire considering the bruxism habit and the presence of headaches and/or restless sleep was answered by the parents/guardians. A clinical exam of occlusion in the anteroposterior direction (vertical plane - VP, mesial step - MS and distal step - DS) was performed by the examiners in the school environment. Student's t test, Fisher's test and a logistic regression test were applied for the statistical analysis at a significance level of 5%. The prevalence of the bruxism habit was 29.3% among the total sample. Because there was no significant difference between the sides evaluated, the left side was taken as the standard. Among those children with bruxism, 25.7% presented a mesial step Terminal Relationship at the primary second molars, 29.1% had DS, and 30.2% had VP. Regarding the association of the parafunctional habit with the type of Terminal Relationship, no significant results were found. Children who slept restlessly or suffered from headaches were verified to show a higher chance of expressing the habit (OR = 2.4 and 1.6, respectively). The prevalence of bruxism in the studied sample was 29.3%, and its association with the primary second molars' Terminal Relationship was not statistically significant.
