Prevalence of malocclusion and orthodontic treatment need in schoolchildren – An epidemiological study

Abstract

Method: Five schools were randomly selected among Army/KV/AF schools and a random sample of 1200 children aged 10e15 years old attending these schools dependant on armed forces personnel were selected. A survey form was filled up after the examination of children by the principal worker and need for orthodontic treatment was assessed using index for orthodontic treatment need (IOTN) and overall oral health status by DMFT index and totaled. Frontal intra oral photograph in centric occlusion were taken. Dental Health Component (DHC) of IOTN for all the patients was marked by one set of orthodontists. The most severe occlusal trait was identified by the examiner for any particular patient and the patient was then categorized according to this most severe trait. AC of the IOTN was assessed by second orthodontist, individual and a layperson. There is significant relation between higher DMFT index and orthodontic treatment need.It was found that IOTN is a reliable and user-friendly index, which can be used for orthodontic surveys. ª

Prevalence of Need of Orthodontic Treatment in 7–16-Year-Old School Children in Udaipur City, India

“…The results of our study were in agreement with the reports of the previous studies of the similar nature comprising different population groups (15,16,21,23,24,27,30). In contrast, the lesser prevalence of Grade 4 (6.4%) and Grade 5 (2.6%) was reported in Iranian school children (19).…”

“…This finding is supported by the reports of the earlier researches (19,23,27). Other studies of similar nature found no variation between the male and female children for the different IOTN grades, thereby opposing the view of gender bias (13,16,18,21,22,(24)(25)(26)28,30).…”

“…Researches around the world have used IOTN to determine the need of malocclusion treatment in different population groups (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). DHC of IOTN is considered as an objective and synthetic method of verifying the malocclusion status and need of orthodontic treatment.…”

Prevalence of Malocclusion among 12 to 15 Years Age Group Orphan Children using Dental Aesthetic Index

“…While there are evidence that certain features such as stress, traumatic deep overbite, unprotected incisors and impacted teeth may adversely affect the longevity of the dentition. 6 As orphans are often denied from oral health information due to number of reasons, for example-in-accessibility, nature of the disadvantage that may necessitate participation of specialized professionals. 7 The various epidemiological studies stated prevalence of malocclusion varies from country to country and among different age and sex group.…”

Rate of intrusion of maxillary incisors in Class II Div 1 malocclusion using skeletal anchorage device and Connecticut intrusion arch

“…3 One of the prominent features of the class II malocclusion is increased overbite. Correction of increased overbite is one of the important objectives to be achieved in this type of malocclusion.…”
