“…The prevalence of class I malocclusion seen in the present study (69.8%) is almost similar to the findings by Trehan et al 11 in Jaipur (57.9%) and Das and Reddy 12 in Bengaluru (61.6%), India. This is found to be higher according to studies of Phaphe et al 13 in Bagalkot (17.8%) and Vibhute et al 14 in Mumbai (49.1%), India and lower when compared to the findings of Mtaya et al 5 in Tanzania (93.6%) and Ajayi 7 in Nigeria (80.7%).…”

Background: A malocclusion is an irregularity of the teeth or a malrelationship of the dental arches beyond the range of what is accepted as normal.Objectives: To determine the prevalence of malocclusion in children aged 10-12 years in Kozhikode district of Kerala, South India.Materials and methods: A descriptive cross-sectional study was conducted among schoolchildren aged 10-12 years in six schools in Kozhikode district of Kerala, South India. A total of 2,366 children satisfied the inclusion criteria. Occlusal characteristics like crossbite, open bite, deep bite, protrusion of teeth, midline deviations, midline diastema and tooth rotation were recorded. The data were tabulated and analyzed using Chi-square test.Results: The results revealed that the overall prevalence of malocclusion was 83.3%. Of this, 69.8% of the children had Angle’s class I malocclusion, 9.3% had class II malocclusion (division 1 = 8.85%, division 2 = 0.5%) and 4.1% had class III malocclusion; 23.2% showed an increased overjet (>3 mm), 0.4% reverse overjet, 35.6% increased overbite (>3 mm), 0.29% open bite, 7.2% crossbite with 4.6% crossbite of complete anterior teeth, 63.3% deviation of midline, 0.76% midline diastema and 3.25% rotated tooth. No significant differences in gender distributions of malocclusions were noted except for increased overjet and overbite.Conclusion: There is high prevalence of malocclusion among schoolchildren in Kozhikode district of Kerala. Early interception and early correction of these malocclusions will eliminate the potential irregularities and malpositions in the developing dentofacial complex.How to cite this article: Narayanan RK, Jeseem MT, Kumar TVA.

“…When compared with our study, a higher prevalence of malocclusion was reported by Abu Alhaija et al 8 in Jordan (92%) and Rwakatema 9 in Tanzania (97.6%). But the studies conducted by Hemapriya et al 10 in Kancheepuram (75%) and Trehan et al 11 in Jaipur (66.7%) reported a lower prevalence than the present study.…”

“…The prevalence of malocclusion was 66.7% in a study done in Jaipur out of which 57.9% had Angle's class I malocclusion. Lower incidence of Angle's class II division 2 (1.9%) and Angle's class III malocclusion (1.4%) was observed [6]. In a similar study, prevalence of malocclusion was 36.42% out of which 29.74% had mild to moderate malocclusion and 6.68% had a more severe malocclusion.…”

With a population of more than one billion, India is the most populous democracy in the world, second in population next to China and seventh largest country in the world by area. Being a vast and diverse country with such a huge population, there exist differences in demography, nutrition, culture, feeding habits, ethnicity and religious beliefs. People are residing at various geographic areas; from the hilly terrains of Himachal Pradesh to the deserts of Rajasthan and from metropolitan cities like Delhi and Mumbai to the tribal corners of this country. Though various studies have been conducted among diverse Indian regional populations, there are no reviews comparing the state-wise prevalence of malocclusion in India. In this review, a few epidemiological studies on state-wise prevalence of malocclusion traits in India are highlighted and further compared, so as to ascertain the epidemiological diversity of orthodontics in a huge country like India.

“…The study sample was divided into five groups according to the type of Angle class I malocclusion which is type 1 (anterior crowding), type 2 (protrusive maxillary incisors), type 3 (anterior crossbite), type 4 (posterior crossbite) and type 5 (mesialization of permanent molars). 22 The TMJ position was measured in relation of two reference lines. The 'X' axis was referred to vertical T line and 'Y' axis was formed by TC line.…”

Evaluation of Changes in TMJ Position for Angle Class I Malocclusion After Orthodontic Treatment by Using Cephalometric Radiograph

et al. 2017

Objective: A concern in fixed appliances orthodontic treatment besides reestablishing the normal occlusion characteristics might cause repositioning of the condyle position in TMJ region. The objective of this research is to find out whether there is a difference of TMJ position in Angle class I malocclusion type 1, 2, 3, 4, and 5 before and after fixed appliances orthodontic treatment. Methods:This research is a pre-and-post design study with analytical statistical approach which compared the TMJ position obtained from tracings 80 lateral cephalometric radiographs before and after fixed appliances orthodontic treatment. Purposive sampling technique was used to determine the sample size in Orthodontic Department of Rumah Sakit Gigi dan Mulut Universitas Padjadjaran from 2009-2015. The data was analyzed by using Kolmogorov-Smirnov Test and paired t-test.Results: This study revealed that the changes of condyle position in Condylion to Vertical T line (horizontally) after orthodontic treatment is not significant (P> 0.05) in Angle class I malocclusion. However, the difference of condyle position in Condylion to TC line (vertically) shows a significant difference (P< 0.05) in Angle class I malocclusion. Conclusion:The distance of the condyle from Condylion to TC line increased after fixed appliances orthodontic treatment for Angle class I malocclusion patients.
