Abstract: Malocclusion is an important oral health issue. Its effects on oral function and facial aesthetics have become a major concern. This study aimed to obtain the profile of malocclusion in grade 10 students of SMA Negeri 9 Manado. This was a descriptive study with a cross-sectional design.

The results showed that the majority of respondents had malocclusion of Angle class I classification Dewey modification as many as 23.3% of type 2 and 20% of type 1. Malocclusion of Angle class I type 5 was found in 3.3% of respondents. Respondents with Angle Class II Division 1 and Division 2 were 13.3% each. Respondents with Angle Class III type 1 were as many as 6.7%. Conclusion: Malocclusion Angle classification Dewey modification with the highest percentage was class I type 2. Malocclusion of class II division 1 and division 2 had the same percentage.

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.

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 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.

The aim of this paper was to determine the prevalence of malocclusions in 12-year-old schoolchildren from Cuenca, Ecuador. A cross-sectional study was carried out, including a clinical examination of 181 schoolchildren aged 12 years, who were randomly selected from the schoolchildren population. We assessed the presence of malocclusions using the Angles classification. The analysis was performed in the program EpiInfo 7.2. The majority of the patients presented malocclusions (91.7%). There is no significant difference between public and private schools and the male sex was slightly more affected. There was a predominance of the Class II division 1 (30.4%), followed by Class III (25.4%), and Class I (24.9%), with the lowest prevalence reported for Class II division 2 (11%). A high rate of malocclusion was found in in 12-year-old schoolchildren from Cuenca, Ecuador, in both males and females. The dominant malocclusion in this study was Class II division 1.

Introduction: Dental arch width measurement is needed to determine diagnoses and orthodontic treatment planning of Angle Class II Division 1 and Class II Division 2  malocclusions that have narrow maxillary dental arch generally. Dental arch width in this study was measured by maxillary and mandibular intercanine width.  This study aimed to compare the differences of intercanine width between Angle Class II division 1 and Class II division 2 malocclusions. Methods: Descriptive comparative research with total samples of 67 study models, consisted of 34 Class II division 1 cases and 33 Class II division 2 cases. The minimum age of the samples chosen was 13 years old with no history of orthodontic treatment. A non probability consecutive sampling technique was used. Results: Study results showed the avarage maxillary and mandibular intercanine width of Class II Division 1 were 33,99 mm and 26,33 mm. Average maxillary and mandibular intercanine width of Class II Division 2 were 34,77 mm and 25,37 mm. Conclusions: T-test analysis showed no statistical significant differences in the intercanine width between Angle Class II Division 1 and Class II Division 2  malocclusions.
