Abstract

Background: Malocclusion is one of the main problems concerning the oral cavity. This study examined the possible effect of mouth breathing habits in patients with respiratory tract allergies on the dental occlusion.Materials and methods: The study was conducted on 150 patients having allergic rhinitis, asthma or both ranging in age from 5-19 years. A group of 150 healthy individuals matched with gender and age to the study group was used as a control group. The total sample was questioned about their mode of breathing then their occlusion was examined clinically.Results: Significantly higher percentages of mouth breathers were found among the study group (P<0.05). Similarly CLII and CLIII dental occlusion, displaced teeth as well as crowding affected significantly greater percentages of allergic patients in comparison to the control group.Conclusion: Mouth breathing habits in patients with respiratory tract allergies may have an additive role in the development of some undesirable malocclusions

Abstract

Background: Information concerning the maximum bite force in human population is important to clinicalorthodontics. Additionally, the influence of bite force on the vertical stability of any treatment result is important. Thenew position of the dentition should be compatible with the dynamics of the muscular and occlusal forces in allplanes. This study was conducted to assess the maximum bite force in the molar (left and right) and incisor region ofIraqi adult persons aged 18-25 years.Materials and method: The total sample size is (150) persons (75 male, 75 female) of untreated Iraqi subjects dividedaccording to the class of malocclusion. The maximum bite force measurements were performed by a digital device(GM10) placed in the first molar area unilaterally on both the left and right sides which was used especially for thisstudy. After that measured the maximum bite in the right central incisor region.Results: The maximum molar force was higher in class III followed by class II and then class I. The maximum incisalforce was higher in class I followed by class II then class III.Conclusions: there was a very high significant difference between molar and incisal bite force. There was nonsignificant difference between right and left side in all classes of malocclusion. Generally there was a very highsignificant difference regarding the genders, males have a greater bite force than females for class I, II, IIImalocclusion.

Abstract

This study was carried out to assess the occlusal features in two Iraqi rural populations, to evaluate the prevalence of these criteria, to explore the difference in these features between the two communities and to provide data base for the malocclusion add to the available informations mainly in rural areas. A sample of(268) males with age range(12-18) years(139 persons from Al-Sharkhan and 129 from Al-Shamsiat rural areas. The statistical analysis revealed that the normal occlusion form(38%) for the two areas while the Class I malocclusion appeared in(54.1%) of the total sample, but Class II division 1 and 2 occurred in(8.2%),(2.2%) respectively, and lastly the Class III malocclusion noticed at(6.3%). The most commonly occurring feature was the generalized dental spacing(40.31%) followed by the generalized crowding(23.25%), and deep bite of which the total overlapping of the lower anterior teeth was occur in(7.08%). Nevertheless, open bite noticed at(1.49%) of the total sample. In this research, there was only a significant difference between the samples of two rural areas at the generalized dental crowding, spacing and in the slight and extreme increase in over jet. Also the unilateral cross bite,buccally erupted canines were more common than the bilateral one.

Abstract

Aims: To find the association between different Angle’s classes of malocclusion and to estimate the distribution of hypodontia according to gender, number of missing teeth and the site of the missing teeth. In addition, the heredity role in hypodontia was investigated. Materials and Methods: About 3415 subjects, 1750 females and 1665 males aging between 18–30 years were examined clinically in addition periapical radiographs were taken for each patient to exclude a possibility of impaction. A family history of hypodontia for each patient was taken (for father, mother, brothers and sisters). Then the sample was divided into 3 groups depending on Angle’s classification of malocclusion. Results: No clear association was found between Angle's classes and hypodontia, females showed higher prevalence of hypodontia than males. Family history was obvious in patients with hypodontia. The upper lateral incisor was the most frequent absent tooth. Conclusions: No association was found between Angle’s classification and hypodontia. The upper lateral incisor was the most frequent missing tooth. Maxilla was affected by hypodontia more than mandible. Females were affected more than males with very obvious effect of family history on hypodontia.

Abstract

Aims: To reveal the possible soft tissue difference in the upper and lower lip heights, separations and coverage of lower lip to upper incisors in different Angle’s classes of malocclusion, to determine any difference in the mean between males and females for each variable and to find any correlation among the variables. Materials and Methods: Nightly nigh students (52 males, 47 females), 20–23 years of age that was randomly selected from the college of dentistry, University of Mosul.The overall sample was classified depending on Angle’s classification of malocclusion into four groups (Class I, II.1, II.2 and III). For each group, four facial soft tissue variables were measured directly using electronic digital viernier caliper. Results: A major findings that emerged from the research is that the Class I subjects possessed higher values of upper lip length followed by Class II then Class III, this difference is significant between Class I,III and II,III and non significant between I,II. Where as Class III subjects possessed non significant higher values of lower lip length followed by Class II then Class I. The lip separation value is non significantly higher in Class II subjects followed by Class III then Class I. While Class III subjects possessed non significant higher values of lower lip to incisor superior followed Class I then Class II. Conclusions: For each specific Angle’s class of malocclusion, a specific facial soft tissue parameters. The upper lip length is greater in Class I subjects. Class III subjects have the greater lower lip length. The inter–labial gap is larger in Class II subjects.While the coverage of the lower lip to incisor superior is greater in Class III subjects. Most of the variables are higher in males than females. Complex correlations among the studied variables are found that varied between weak to high positive or negative with varying degree of significance.

Abstract

Background: Survey of the occlusion in population groups usually include in their objections the academicassessment of occlusal feature, the planning resources for public health treatment programmers, the comparison ofdifferent population and the screening of groups for orthodontic treatment. Likewise a thorough investigation of theoccurrence of malocclusions among school–students would be of major importance in the planning of orthodontictreatment in the public dental health services. For this purpose it is necessary to have detailed information on theprevalence of individual malocclusion among boys and girls at different ages distributed regionally, and moreover,an analysis of the need for orthodontic treatment in the different school classes.Materials and methods: This study was conducted from 20th October 2011 to 9th May 2013 on (3424 ) students (1712males and 1712 females); from which 62 students (1.8%) were excluded because of incomplete information (nomolar relation can be attended) giving a valid sample of 3362 (1681 males and 1681 females) aged (15) years oldwere studied with respect to facial profile ,sagittal occlusion according to Angle's classification, overjet, overbite,anterior crossbite , posterior crossbite, scissorsbite, rotation and displacement spacing and crowding.Results: The normal profile were presented in (73.76%) students (74%) males and (73.53%) females. Convex profileswere presented (20.34%) students (20.46%) males and (20.23%) females. A concave profile were presented in (5.9%)students (5.54%) males and (6.24%) females), The malocclusion were presented (73.05%) students (73.46%) malesand (72.64%) females, According to the Dental health component of index of the orthodontic treatment subjectswith no need for treatment were about 44.11% , the subjects who need little treatment were about 26.82%, 13.06% ofthe subjects who need moderate treatment, 10.03% great treatment need and about 5.98% very greatly treatmentneed.Conclusions: Orthodontic treatment need according to IOTN shows that there was no significant difference betweenmales and females in the malocclusion, Facial profile and treatment need

Abstract

The aim of this study was to provide an additional information about occlusal variations, and to determine the possible sex difference in a group of young Iraqi who were seeking for orthodontic treatment.A sample of (253) orthodontically treated patients (125 female and 128 male) selected from (3719) patients attending P.O.P department in college of dentistry in Mosul University, for each one the age, sex, molar occlusion in accompanied to some selected malocclusion criteria (crowding, spacing, crossbite and openbite) were recorded. The results of this research evaluated the number, percentage for each type of molar occlusion and the malocclusion criteria. The using of two sided Z-test of twoproportions at (p<0.05) indicate that significant sex difference in CL IIb, CL II1,crowding and spacing and a non-significant difference in CL Ib, CLIu, CL II, CL II2, CL III, CLIV, crossbite and openbite. The occlusal variation for Iraqi follows a universal general distributional pattern for most world populations.

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.
