Department of Surgery

Abstract

This study was planned to determine the prevalence of hypodontia in permanent dentition and to test whether an association was present between hypodontia and Angle's malocclusion. The retrospective study was conducted at a tertiary care hospital, Karachi, and comprised record of all patients visiting the orthodontic clinics of the hospital from 2005 to 2015. Orthodontic records of 790(79%) subjects, including 189(23.9%) males and 601(76.1%) females, were reviewed. Their mean age was 17 ± 5.06 years. A tooth was considered missing if no evidence of tooth germ was observed on orthopantomograms and dental casts. The total sample was distributed into …

Department of Surgery

Abstract

OBJECTIVE:

Class-1 malocclusion commonly presents with crowding and poses an aesthetic concern to patients. An orthodontist may encounter a variety of dental problems and must handle them strategically to establish adequate occlusal relationships. Hence, this study was conducted to evaluate the occlusal characteristics of patients who have undergone non-extraction or all first premolars extraction treatment for class I malocclusion using the peer assessment rating (PAR) index.

METHODS:

The pre-treatment and post treatment dental casts of 94 subjects with class-I malocclusion were retrospectively screened. The sample was distributed into two groups, i.e., nonextraction and all first premolars extraction groups. The …

Reliability Of Overbite Depth Indicator (Odi) And Anteroposterior Dysplasia Indicator (Apdi) In The Assessment Of Different Vertical And Sagittal Dental Malocclusions: A Receiver Operating Characteristic (Roc) Analysis, Farheen Fatima, Mubassar Fida, Attiya Shaikh

Department of Surgery

Abstract

INTRODUCTION::

Differential diagnosis of skeletal and dental relationships is crucial for planning orthodontic treatment. Overbite depth indicator (ODI) and anteroposterior dysplasia indicator (APDI) had been introduced in the past for assessment of vertical and sagittal jaw relationships, respectively.

OBJECTIVE: :

The objectives of this study were to evaluate the reliability of ODI and APDI in overbite and Angle malocclusions, as well as assess their diagnostic reliability among males and females of different age groups.

MATERIAL AND METHODS: :

This study was conducted using pretreatment dental casts and lateral cephalograms of 90 subjects. For ODI, subjects were divided into three …
