Abstract

Supernumerary teeth are those teeth developed along with normal complement as a result of excess dental lamina in the jaws. Developmentally missing teeth include hypodontia, oligodontia and anodontia. Congenital missing of one or more teeth or a supernumerary tooth requires an urgent treatment as suggested by the Index of Orthodontic Treatment Need. This study tries to evaluate the prevalence and distribution of tooth number anomalies in Erbil patients in relation to the side, jaw, tooth types, and gender. Three thousand orthopantomograms of patients (9-36) years' old who is seeking dental treatments are used to determine the spreading and distribution of the hypodontia, oligodontia, and hyperdontia. Their radiographs are retrieved from Orthodontics and Radiographic Clinics at the College of Dentistry, Hawler Medical University, Erbil/Kurdistan Region of Iraq and private dental radiographic clinic in period from 2013 till 2015. A tooth is diagnosed as congenitally missing in case of no identification or discerned radiographically on the basis of calcification or there is no removal evidence. The chi- square test is to determine the importance of the upper and lower numerical teeth abnormality differences and the differences between genders. Five percent was set as the level of significance.Hypodontia was prevalent by 7.76%, it was more often found in females in right side of maxilla. The most missed tooth was maxillary lateral incisor. The permanent congenital missing teeth were frequently in the maxilla. Mesiodens was the most common supernumerary tooth, and its prevalence was 1.13%.

Abstract

Background and objective: Developmentally missing teeth include hypodontia, oligodontia, and anodontia. In the case of absence of one or more teeth or supernumerary one, the need for treatment is very great. Aesthetic concerns, periodontal diseases and malocclusion are some of the complications following hypodontia. This study aimed to find out the prevalence and distribution of hypodontia in Erbil orthodontic patients in relation to the side, jaw, tooth types and gender.Methods: Orthopantomograms of 600 patients (10-34 years old), seeking orthodontic treatment from different orthodontic clinics in Erbil city between 2014 and 2015 were evaluated. A tooth diagnosed as congenitally missing when cannot be identified or discerned radiographically on the basis of calcification and there is no evidence of extraction.Results: The prevalence of hypodontia was 6.66%. Maxillary lateral incisors were most frequently missing (42.68%), followed by mandibular second premolars (19.51%). Hypodontia was more frequently found in females with no statistically significant difference. 62.5% of hypodontia located in maxilla while 27.5% located in the mandible and only 10% was in both arches in the same patient.Conclusion: The pattern and prevalence of hypodontia are different among races and ethnic groups. The prevalence of hypodontia in Erbil orthodontic patients was 6.6%. Upper lateral incisor was the most frequently missing teeth. Tooth agenesis in the upper arch was more prevalent than in the lower arch.

Abstract

Aims: The aims of the study are to evaluate the radiographical views, OPG and periapical views on the changes in peri- implant bony tissue around dental implant at time of placement and another reading after 16 weeks before functional prosthetic loading and regard it as a prognostic parameter. Material and methods: Nineteen cases with 24 implant were enrolled for standardization. Radiographical measurement undertaken by a periapical and OPG radiographs after implant placement, then after16 weeks later, again a second periapical and OPG radiographs were taken for measurements using Dimaxis 3.2.1. Software program to estimate marginal bone height of both sides of implant and its changes during times of evaluation. Results: 19 medically fit patients, male and female with age 22-65 years, twenty four implants with average bone loss 0.59 mm mesialy and 0.60 mm distally at T0 as standered base line in compared to 0.98mm mesialy and 1.11mm distally at T1as average bone loss. There was a significant bone resorption in both sides in relation of implant size and in comparison to time of placement and after 16 weeks according to statistical analysis. Conclusion: OPG and periapical views are a good parameter for evaluation of successful implant and monitoring of the prognosis and stability and durability, as these radiographs more available in most dental centers and clinics with less cost.

Abstract

This is the first study carried out in Iraq to determine the reliability of using new technique to asses inclination of lower permanent teeth as an indicator to asses position of the teeth before and after orthodontic treatment with orthodontic treatment with orthopantomograph.A total (259) students select randomly from Mosul university only (34) students (16 males, 18 females) between (18-25 years old) were of Iraqi origin who fulfilled the criteria of the sample. We found no significant differences (95% confidence level) of mean values of inclination of the teeth between male and female, with a significant difference between right and left sides for both sexes.

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.
