Evaluation of arch width among Class I normal occlusion, Class II Division 1, Class II Division 2, and Class III malocclusion in Indian population

ABSTRACT Background Prevalence of malocclusion varies in different parts of a diverse country like India. Aims To determine the prevalence of malocclusion in population of Jaipur city, Rajasthan, India, as well as subjects views regarding the most important factor for seeking orthodontic treatment by patients who have malocclusion. Materials and methods The sample consisted of 700 subjects (373 males and 327 females) with age group of 15 to 30 years. Subjects were randomly selected and none of them had received orthodontic treatment previously. The subjects who showed bilateral Angle's class I molar relationship with acceptable overjet, overbite and well-aligned arches or minimal crowding were considered to have normal occlusion. The subjects with malocclusion were classified into four groups according to Angle's classification, i.e. class I, class II division 1, class II division 2 and class III malocclusions. Results About 74.57% of population was found to have malocclusion. Among these subjects, 52.57% subjects were diagnosed with class I malocclusion, 12.57% with class II division 1 malocclusion, 8% with class II division 2 and remaining 1.42% had class III malocclusion. No statistically significant differences were found between male and female subjects. Conclusion Among class I malocclusion characteristics, Angle's class I type 1 malocclusion was statistically significantly found to be the most prevalent type of malocclusion. As far as the most important factor for seeking orthodontic treatment was determined, a desire of enhancing facial appearance followed by a desire of attaining straight teeth was considered to be the chief motivational factor among this population.

Objective. The purpose of this study is to investigate the Craniomandibular articulation morphology and position of condyle in mandibular fossae in Angle’s class I normal occlusion and Angle’s class II division 1 malocclusion. Materials and Methods. The present study was conducted on 40 subjects with 20 subjects in each group, and the computed tomography images were obtained using spiral computed tomography technique. Each measurement was compared by two-factor analysis of variance (ANOVA) while changes in anterior and posterior joint spaces were done by paired t-test. Results. Statistically significant anterior positioning of condyle was observed in class I normal malocclusion, and it was significant only on right side in class II division 1 malocclusion. Conclusions. There was no difference found in the condylar process and joint morphology between right and left sides of both Angle’s Class I normal occlusion and Angle’s class II division 1 malocclusion. Evaluation of the position of the condyles in their respective mandibular fossae showed concentric position with a tendency towards anterior positioning for both right and left sides of the subjects with Angle’s Class I normal occlusion as well as subjects with Angle’s class II division 1 malocclusion.

Aim : To evaluate the transverse discrepancy in different malocclusion groups. Also to test the hypothesisvthat models with Class II division 2 malocclusion may have mean maxillary arch widths significantly smaller than those with normal occlusions and significantly larger than those with Class II division 1 malocclusion. Thus the proposed study will generate interest among the orthodontists for further study over the transverse discrepancy of our patients and guide them to establish effective treatment strategy and their management.Methods: This study was a cross sectional study conducted among the dental casts of 150 patients and students of the Department of Orthodontics and Dentofacial Orthopedics, Dhaka Dental College and Hospital. Both male and female were included. The first group consists of 50 pair of study models with permanent dentition and diagnosed as Class I (normal) occlusion. The second group includes another 50 pair of dental casts with permanent dentition and diagnosed as Class II division 1 malocclusion . And third group includes another 50 pair of dental casts with permanent dentition and was diagnosed as Class II division 2 malocclusion. This group of malocclusion was again subdivided into two categories, Class II division 2 malocclusion with crowding and Class II division 2 malocclusion without crowding. The Students t test was used to analyze the data. In this analytical test the level of significance p value <0.05 was considered significantResults: No Statistically significant difference was observed in the maxillary inter canine, inter first premolar and inter first molar widths between class-I and Class-II div-1. Significant differences were observed between two groups. In case of mandibular inter first molar widths (p value = 0.001), and also differences in case of mandibular inter canine, inter first premolar and inter first molar widths between Class-I and Class II div 2 malocclusion p value respectively .01, 0.002,0.01.Conclusion: This study helps in determining possible differences in the dental arch widths of Bangladeshi people in Class II div 2 adults compared to adults with Class II div 1 and normal occlusion may be an important aid in further understanding of dentoalveolar characteristics of these conditions, as well as improving their management.Ban J Orthod & Dentofac Orthop, April 2013; Vol-3, No.2

It is essential to know dental arch dimensions to provide accurate diagnosis and treatment planning to ensure the satisfactory outcome of orthodontic treatment. The aim of the present study was to measure and compare dental arch dimensions of a Kurdish sample in Erbil city with normal and different classes of malocclusion. Arch width and length were measured by an electronic digital caliper on a total of 150 orthodontic models of school students aged 16–20 years of different occlusal relationships (Class I normal occlusion, Class I, Class II division I, Class II Division II, and Class III malocclusions). The results showed that (1) girls have smaller arch parameters than boys; (2) Class II division II malocclusion showed a significantly smaller upper inter canine width, arch length, incisor molar distance, and incisor canine distance when compared to all other groups; (3) the upper inter premolar and inter molar width were significantly narrower in Class II division I malocclusion than of normal occlusions and Class III malocclusion and also narrower in Class I malocclusion than in normal occlusions for both arches; (4) the arch length was significantly longer in Class II division I when compared to Class II division II, Class I malocclusions (P < 0.01), Class III malocclusion and Class I normal occlusion (P < 0.05), and (5) no statistically significant differences were found in all the arch dimensions for Class III malocclusion when compared with the normal occlusion. In conclusion, girls had smaller arch dimension than boys and Class II Division II malocclusion showed smaller arch in all dimensions while Class II division I malocclusion revealed narrower arch width and longer arch length.

Type Of Delivery

The aim of the investigation was to determine the dynamic of birth delivery and relate to dental occlusion among a group of adult subjects. The group studied was made up of 106 subjects (57 females and 49 males) referred for dental diagnosis and treatment. The average age was 26 with a range 22 to 30 years. In data collection and analysis the following were used as measures: dental occlusion (Angle Class I, II div 1, II div 2 and III) and type of delivery (normal, short, long, caesarean and other). Results showed that among 106 subjects 72 (68%) had malocclusion versus 34 (32%) with normal occlusion; 24 subjects (22.6%) have been normal delivery versus 82 (77.4%) with non-normal delivery. Class I is present in 34 subjects (32%), class II division 1 in 26 (24%), class II division 2 in 22 (20%), class III in 16 (14%), and 8 subjects (6%) fall in the section "other". Among 24 subjects with normal delivery 100% presented class I occlusion. However, among 82 subjects with non-normal delivery 10 subjects had a class I (12.2%) and the 72 (87.8%) had in the other classes, are distributed in the various subgroups of non-normal labor/delivery. None of the subjects with a malocclusion have a normal labor/delivery. Better understanding of the connections among osteopathic theory, craniosacral treatment and the outcomes upon dental occlusion, more rigorous evaluations are warranted.

Introduction: Altered nasorespiratory function leads to altered craniofacial growth. Thus, airway evaluation is important for preventive, interceptive, and corrective orthodontic treatment. The aim of this study was to evaluate and compare adenoids, the upper airway, the tongue, and mandibular dimensions using “predictors of difficult airways” in class II division 1 and class II division 2 cases with class I cases. Method: Sixty subjects of age 15 to 18 years were divided into 3 groups (group 1: class I cases; group 2: class II division 1 cases; and group 3: class II division 2 cases) based on cephalometric parameters, with 20 cases in each group. Cephalometric evaluation of adenoids and the nasopharyngeal airway was done using the Handelman–Osborne area method. Upper and lower airway evaluation was done using McNamara’s linear method. “Predictors of difficult airways” were used for evaluation of the airway, which included nasal competency, the Mallampati scale, mandibular length, mandibular protrusion, and the thyromental distance. Results: The present study found a significant positive correlation between the grades of nasal competency and percentage adenoid wall area, and a significant negative correlation between the grades of nasal competency and the upper airway. There was a significant positive correlation between the grades of nasal competency and mandibular length, and a significant positive correlation between the grades of mandibular protrusion and mandibular length. There was a significant positive correlation between the grades of the thyromental distance and mandibular length. Conclusion: It was concluded that the “predictors of difficult airways” would be helpful in early diagnosis and identification of potential risk factors that may cause “breathing disorders”–related malocclusions and later on increase the risk of developing OSA.

Abstract Objective: To investigate the effects of different occlusion types on the mandibular asymmetry in young individuals. Materials and Methods: Mandibular asymmetry measurements were performed on the panoramic radiographs of 189 subjects (104 females and 85 males; age range, 11–15 years), with different occlusion patterns. The subjects were divided into five groups according to the occlusion types, namely, Angle Class I (Cl I), Class II division 1 (Cl II/1), Class II division 2 (Cl II/2), Class III (Cl III), and normal occlusions. The Kruskal-Wallis test was used to determine the possible statistically significant differences between the groups for condyle, ramus, and condyle-plus-ramus asymmetry index measurements. Identified differences between groups were further analyzed using the Mann-Whitney U-test at the 95% confidence interval (P < .05). Results: There were no statistically significant differences between male and female subjects. The Kruskal-Wallis test showed that the occlusion type had a significant effect on the condylar asymmetry. In Cl II/1 cases, condylar asymmetry values were significantly different from the values of Cl II/2 and Cl III malocclusion and normal occlusion types. The normal occlusion control group was significantly different from those of Cl II/1 and the Cl I malocclusion groups. Conclusion: Cl II/1 malocclusion has a significant effect on the condylar asymmetry index when compared to Cl II/2 and Cl III malocclusion and normal occlusion types. However, the mean condylar asymmetry index value in Cl II/1 malocclusion was not different from Cl I malocclusion.
