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.

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.

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.

Abstract Background: Previous studies regarding various types of malocclusions have found correlations between the angle of the base of the skull and prognathism. Aim of the study: This cephalometric study sought to investigate the function of the cranium base angle in different types of malocclusion on a group of Romanian subjects. Materials and methods: Forty-four cephalometric radiographs were selected from patients referred to orthodontic treatment. The cephalometric records were digitized, and with the CorelDRAW Graphics Suite X5 software 22 landmarks have been marked on each radiograph. A number of linear and angular variables were calculated. Results: The angle of the base of the skull was found to be higher in Class II Division 1 subjects compared to the Class I group. The cranial base lengths, N-S and S-Ba, were significantly larger in both categories of Class II malocclusion than in Class I patients, but measurements were comparable in Class I and Class III. The SNA angle showed no considerable variation between Class I subjects and the other groups. SNA-SNP was significantly increased above Class I values in Class II Division1 and Class II Division 2 groups. No significant dissimilarities were observed for these lengths between Class I and Class III patients. Conclusions: The angle of the cranium base (S-N-Ba, S-N-Ar) does not have a major role in the progression of malocclusion. In Angle Class II malocclusion the SNA angle is increased, and SNB is increased in malocclusion Class III. The anterior skull base length is increased in Class II anomalies. The length of the maxillary bone base is increased in Class II malocclusions type; in Class III type of malocclusion the length of the mandible bone is increased.

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 Student’s 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

Aim: Technologies related to big data are progressively used for various research purposes in the fields of dentistry and health-care informatics. Large amounts of clinical data have been achieved and acquired at an exceptional acceleration and advancement. The actively developing field of big data analysis has started to play a critical and decisive role in the progression of dental practices and research. It has implemented tools to collect, regulate, interpret, and comprehend enormous volumes of distinct, structured, and unstructured data established from the present healthcare systems. Big data analysis has been lately devoted in the direction of encouraging and assisting the process of problem detection and care delivery. Our study aimed at measuring the frequentness of orthodontic problems, incidence of malocclusion and the orthodontic treatment demand among children who attend secondary schools in Northern Cyprus. Methods: For the present survey, our sample included 426 school children (203 females and 223 males) who are 12–15 years of age. Molar relation in each child was assessed according to Angle's classification. To evaluate the need and demand for orthodontic treatment, the ICON index was then used. Occlusal features such as overbite and overjet were measured and the presence of malocclusal characteristics such as cross bite, deep bite or open bite was examined and recorded for each subject. Our findings indicated that among this Northern Cypriot school population: (20.6%) had no occurrence of malocclusion, (74.6%) were found to have a Class I molar relation, (21.1%) had a Class II molar relation (Division 1, 13.6%; Division 2, 1.6%) and (3.3%) had a Class III malocclusion. Moreover, (20.2%) of all the examined children were found in need of orthodontic treatment. Digital modelling derived from CBCT scanning of plaster casts is a reliable method to assure the accuracy of measurements obtained directly from clinical and dental examination. Results: 74.6% of all subjects were found to have class I dental malocclusion; class II division 1 were calculated at 13,6%, class II division 2 were 1,6%, class II subdivision 4,2%, class III were calculated to be at 3,3% and class III subdivision 2,5%. Conclusion: The most common orthodontic malocclusion in Northern Cypriot school children is Class I and the least common one is Class II division 2.

Abstract Objective The main purpose of this article is to evaluate the disclusion time (DT) in the lateral excursions and protrusion among subjects with Angle’s malocclusions using a T-Scan III system. Materials and Methods One hundred subjects with malocclusions were divided into Class I, Class II division 1, Class II division 2, and Class III (n = 25 per group). All groups’ DT of each excursion was evaluated by a T-Scan III system. Statistical Analysis One-way analysis of variance, followed by a post hoc test, was used to analyze the numerical data at p < 0.05. Results In the respective malocclusions, means ± standard deviations in second(s) of the DT were 2.08 ± 0.65, 2.13 ± 0.74, 2.12 ± 0.72, and 3.19 ± 1.34 during left excursion; 2.15 ± 0.94, 2.58 ± 1.16, 2.37 ± 1.07, and 3.28 ± 1.25 during right excursion; and 1.88 ± 0.99, 2.08 ± 1.11, 2.07 ± 0.68, and 3.01 ± 1.53 during protrusion. When compared to Class I and Class II malocclusions, Class III showed a significantly higher mean DT of each excursion (p < 0.05). Conclusion Class III had the significantly highest mean DT of each excursion and the significantly longest DT in all excursions.
