frequency of deep bite in orthodontic patients at the armed forces Institute of Dentistry, Rawalpindi

The objective of this study was to evaluate the frequency of deep bite among orthodontic patients who presented at the Department of Orthodontics, AFID, Rawalpindi during a time period of 7 years. The orthodontic treatment records of 1856 patients were evaluated for the presence of anterior deep bite. Patient's study casts and pre-treatment photographs were used for this propose. All the patients included in the study were in the permanent dentition stage. Three hundred sixty eight patients out of 1856 had anterior deep bite with an incisor overlap of more that 3 mm. Of these, 368 patients 238 were females and 130 were males. The patients were divided into two groups. Grade 1 deep bite, having an incisor overlap of more than 3 mm without palatal irritation and Grade 2 deep bite, having an overlap of more than 3 mm with trauma to the palatal mucosa. The occurrence of deep bite among these patients was 19.8% out of which 64.6% were females and 35.4% were males

Frequency of anterior bite patients reporting to AFID, Rawalpindi

The purpose of the present study was to calculate the frequency of an anterior open bite in a set of population comprising of military as well as civilian patients reporting to orthodontic department of Armed Forces Institute of Dentistry [AFID], Rawalpindi, from all over the country. Out of a total sample of 1856 patients reporting to AFID from 2001 through 2008, 1800 patients fulfilled the inclusion criteria. Dental records including photographs and casts were assessed for the presence of anterior open bite. The frequency of open bite from the total sample and its percentage with respect to gender and age was calculated. The frequency of open bite was found to be 4%. The mean age of patients was 21.6 years. Females were twice as frequently affected as males. Simple anterior open bite was more prevalent. It is self evident that this is one of the most difficult malocclusions to manage and maintain in orthodontics. Its treatment should be primarily etiology oriented and preferably customized so as to prevent the chances of relapse
