Abstract

Dental trauma is a public health problem in young aged patients. The aim of thisstudy was to investigate the percentage and severity of dental trauma andmalocclusion and their correlation, as well as analyze the general risk factors like theeffect of age, gender, causes of the trauma and malocclusion in anterior permanentteeth.The sample of the present study include patients who came to the Pedodonticclinic in the Pedodontic and Preventive department at the College ofDentistry/Baghdad University seeking treatment of traumatized anterior permanentteeth. The traumatized teeth were examined clinically (according to Garcia-Godyclassification) and radiographically. Types of occlusion was determined according toAngle’s classification, while the over jet and overbite were recorded according to thecoding criteria described by Kinnan’s study.In all age groups, the most frequent cause of trauma was found to be falls (61.4%).Enamel and dentin fracture was the most frequently seen type of injury(38.6%) inwhich upper central incisors were the most affected teeth from dentaltrauma(47.7%).Regarding malocclusion, patients with class II malocclusion represent(71.9%) from the total sample, while those with increased over jet (26.3%) in which(66.7) of them seek treatment for two fractured teeth. However, the number of injuredteeth per child was 1.54. Increased overbite was correlated with more sever type ofdental trauma.There is a relationship between malocclusion and fractured anterior teeth in whichmalocclusion will increase the number of fractured teeth as well as the severity of dental trauma.

Abstract

Background: The attempt to make good diagnosis enforce the orthodontists to examine the relationship of themandibular incisors position in patients with malocclusion to provide the practitioners with more diagnostic normsand correlation equation. This study aimed to determine the position of the mandibular incisors in a sample of adults(aged 18-25 years) with Class I malocclusion, to determine the existence of gender differences in mandibular incisorsposition, and to determine the correlation between the mandibular incisors position with some measurements.Materials and method: Lateral cephalometric radiographs were taken for 60 adults subjects (30 males and 30females). The cephalometric radiographs were traced and verified using AutoCAD 2008 program.Results and Conclusions: The results show non-significant gender difference in the position of the mandibular incisors,and very high significant direct correlation between GoGn-NB angle and the ˉ1ˉ-NB. The GoGn-NB angle can beclassified as most important of the guiding angular variables in determining the lower incisors position (ˉ1ˉ -NB).

Abstract

AbstractThis study aimed to provide a description of the mesiodistal axial angulation of themaxillary and mandibular teeth in cases of class I malocclusion.The values of the mesiodistal axial angulation of the teeth were measured for 20subjects (10 males and 10 females) from orthopantomograph using computer programand comparisons were made between the right and left sides and between males andfemales.The mean values of the mesiodistal axial angulation of the teeth were higher inmales than in females, and higher on the right side in upper and lower arches than onthe left side for males, females and total sample, however; there was no statisticallysignificant difference between the groups. This study provided a good description ofthe mesiodistal axial angulation of the maxillary and mandibular teeth in cases ofclass I malocclusion.
