ABSTRACT
The purpose of present study was to determine association of dental anomalies observed in various dental malocclusion patients visiting for Orthodontic treatment. Total of 600 patients [169 male, 431 female] having mean age 17.25+/-5.55 years were evaluated. This study showed that 61.2% of patients [n = 600] presented with at least one dental anomaly. Ectopic eruption was the most commonly found [46.8%], followed by Agenesis [missing tooth or teeth] 9.0%, canine impaction 4.0% and supernumerary teeth 1.3%. The frequency of theses dental anomalies were found higher in female than in males. Ectopic eruption [56% within malocclusions] was more frequent in patients with Class II div 1 malocclusion. No supernumerary tooth was found in Class II division 2 malocclusion rather more prevalent in class III malocclusion [2.5%]. Impaction was associated with Class II div 2 malocclusion [11.1%], at a higher prevalence than other types of malocclusions. Agenesis was associated with Class II div 2 malocclusion and class III malocclusion [14.8]. The correlations between dental anomalies and different types of malocclusion were found statistically significant. Within limitation of this study, Dental anomalies recorded frequently higher in females than male subjects, the reason may be the female patients being more esthetically conscious, visiting orthodontic treatment in Pakistan
ABSTRACT
The objective of the study was to compare the Mean Tooth Attrition Score in psychiatric patients with depression, with healthy individuals of same age groups. A Case control study was carried out in the Department of Prosthodontics, Armed Forces Institute of Dentistry and Psychiatric Department, Armed Forces Institute of Mental Health, Rawalpindi, from August 2010 to March 2011. Seventy patients were divided into two equal groups, A and B. Group A comprised of 35 psychiatric patients with depression under treatment since one year having minimum ten natural teeth in oral cavity including first molars and incisors selected from Armed Forces Institute of Mental Health while group B comprised of 35 otherwise healthy individuals of same age range reported to AFID for routine dental treatment. They were included by Non probability consecutive sampling method. The patients with history of facial trauma, hormonal disease or neoplasm, having carious or restored molar teeth and malocclusion were excluded from the study. Smith and Knight[1] index with scores ranging from 0 [No loss of enamel] to 4 [Complete loss of enamel] used to measure tooth attrition score of central, lateral incisors and first molars. The data were analyzed with SPSS version 16. In this study, a significant difference between groups for mean tooth attrition score was found. Psychiatric patients with depression and anxiety revealed the highest degree of tooth wear, many of them requiring complex treatment
