Crossbite is one of the most prevalent malocclusion, posterior crossbite occurs in 8% to 22% of orthodontic cases and anterior crossbite has been seen in Class III cases, which accounts for 3.4% of orthodontic cases. The etiology of posterior crossbite can include any combination of dental, skeletal, and neuro muscular functional components, but the most frequent cause is reduction in width of the maxillary dental arch. Patients/cases seeking comprehensive orthodontic treatment in between 5 to 35 years were diagnosed for crossbite with diagnostic model and care record file. Out of 300 cases 163(54.3%) had crossbite, 90(30%) had anterior crossbite and 109(36.3%) had posterior cross bite. Among posterior crossbite 60(20%) had unilateral and 49(16.3%) had bilateral crossbite. Posterior crossbite was more prevalent than anterior crossbite. Cases with Class I molar relation showed more crossbite. Crossbite was more prevalent in cases with congenitally missing teeth.Bangladesh J Medicine Jan 2015; 26 (1) : 9-12

BACKGROUND To provide efficient and well-planned orthodontic treatment orthodontists must be able to assess the type of malocclusion and the complexity involved in its treatment. Hence, the purpose of this study was to validate index of orthodontic treatment complexity (IOTC) as a reliable index to assess the treatment complexity in treating different malocclusion groups. METHODS A retrospective study with sample of 120 pairs of orthodontic study model consisting of treated and untreated cases, were collected and equally divided into class I, class II including both division 1 and division 2 and class III malocclusions based on Angles system of classification of malocclusion. Study casts were scored according to criteria given by the index of orthodontic treatment complexity and the degree of complexity is established for each of the malocclusion groups and the occlusal traits. RESULTS The Spearman correlation coefficients test shows that occlusal traits like overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite, alone significantly correlated with degree of complexity. Multiple regression analysis and one way ANOVA tests were performed for the three types of malocclusion and the test showed that in individual classes of malocclusion, the predictor variable (occlusal traits) significantly predicts the degree of complexity in class I and class II malocclusion cases, but not in class III. CONCLUSIONS Overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite correlated with degree of complexity. IOTC forecasts the degree of complexity in class I and class II malocclusion cases, but not in class III. KEY WORDS IOTC, Malocclusion, Occlusal Traits

Introduction: Malocclusion affect the esthetic, function of the patients, so they seek orthodontic treatment for normal function and healthy and beautiful smile. Increase in public awareness and availability of orthodontic specialty services have led to increasing number of orthodontic patients in specialty clinics and hospitals. The objective of this study is to examine the pattern of malocclusion in the patients visiting medical and dental teaching hospitals and dental clinics and to measure the different Angle’s classification of malocclusion with discrepancies in all three planes. Materials and Method: Three hundred seventeen acceptable study casts were selected from 403 case records of orthodontic patients who visited the different hospitals and private clinics of Province 2, Nepal. A standard guidance of Angle’s classification was used to classify the cases and casts were measured to record the data. Different Angle’s classification of malocclusion with discrepancies in all three planes was studied. Descriptive statistics (frequency, percentage, mean and SD) and inferential statistics (chi square and fisher exact test) was used to find out the association between occlusal traits and demographic variables. Result: According to the Angle’s classification of malocclusion, most of the patient’s cast 65.9% were of class I, followed by class II 31.8%, class III 5.3% occlusion pattern. Among the class II malocclusion, class II division 1 malocclusion was more prevalent (86.13%). Under space discrepancies, crowding of teeth was present in 42.58% of patient. Of the total teeth crowding patient, 70.3% had crowding of teeth in both the arches followed by only mandibular arch (25.18%). There is statistically significant association between the age and the occlusal traits like crowding (p value 0.008), spacing (p value 0.000) and overjet (p value 0.000) at 0.01 level of significance. Conclusion: Angle’s class I was the most prevalent malocclusion followed by class II and class III. Increased overjet was the commonest occlusal trait. There was statistically significant association between the age and occlusal traits like crowding, spacing and overjet.

The Impact

As the COVID-19 pandemic is steadily rising, there is an increase in psychological distress among the orthodontic patients regarding their ongoing treatment. Thus aim of the study was to assess the anxiety and perceptions among orthodontic patients regarding the impact of COVID-19 pandemic on orthodontic treatment. A closed end online questionnaire was sent as Google forms to 300 adult patients’ currently undergoing orthodontic treatment at a tertiary care center. 266 patients answered the survey with a response rate of 88.7%. Online consent was taken before participation in the study and the survey was anonymized and did not contain any identifying information. The descriptive data included the participants' responses using frequency and proportions. The difference in the distribution of responses were compared using Chi-square goodness of fit test and the level of significance was fixed at p < 0.05. Level of anxiety between males and females was compared using independent t-test. Among the respondents, 126 were males and 140 were females. The mean level of anxiety level among males was 4.28 ± 2.28 whereas for females it was 5.85 ± 2.48. The differences in the distribution of responses by the participants were statistically significant. The COVID-19 pandemic showed to have a greater impact on orthodontic appointments and anxiety levels of patients. Females showed greater anxiety than males for visiting the dental clinics. The greatest concern that patients reported was the increase in their treatment duration and they also recognized the importance of monthly orthodontic reviews.
