Aim: To determine the most common rugae pattern and to find if it has any association with dental arch form or malocclusion. Study Design and setting: It was a retrospective cross-sectional study conducted using the records of 200 patients visiting the Orthodontic Outpatient department of Bahria University Medical and Dental College. Methodology: Number, size, orientation and pattern of palatal rugae were assessed on the plaster models. Dental malocclusion along with dental arch form and width were also evaluated. Descriptive statistics such as frequencies were analyzed. Chi square, Fischer exact test and One Way ANOVA was used to see the significance of differences, p≤0.05 was considered as significant. Results: The sample comprised of class I (n=97), class II(n=87) and class III(n=16).113 cases had inter-molar width >44mm while 87 had ≤44mm. Posterior orientation of the rugae, was pre-dominant for both right (n=100) and left (n=122) first rugae. The most common pattern was curved for both first rugae on right (n=66) and left (n=72) sides. Conclusion: Our study showed that the rugae pattern, size and numbers did not show significant variation in different malocclusion classes. It can be concluded that rugae pattern do not have any significant association with malocclusion class or arch form. Keywords: Arch form, Arch width, Forensic dentistry, Malocclusion, Palatal Rugae

Dental Arch Length

Background: Dental arch form and dimension are fundamental factors in orthodontic diagnosis and treatment planning. Its dimension will increase, due to the eruption of teeth, and is also affected by ethnicity, nutrition, systemic disease, hormonal factors, and gender. Many teeth are erupting in 8–10-year-old children. Purpose: This study aimed to assess the correlation between age and dental arch dimension of Javanese children in good nutritional status for consideration of orthodontic treatment. Methods: This was a cross-sectional study with 66 children aged 8–10 years in a normal dentoskeletal relationship, grouped based on age as the subject. Each group consisted of 22 pairs of dental study models, male and female. Anterior and posterior size of dental arch length were measured by digital sliding calipers from the midpoint between the right and left permanent central incisors perpendicular to the inter-canines and inter-molars. The width was measured at the inter-canines and inter-molars. Results: Pearson’s correlation test showed that there were significant correlations between age and maxillary dental arch lengths (p = 0.01, r = 0.31 for anterior, and p = 0.043, r = 0.249 for posterior). Conclusion: Based on this study, it can be concluded that there was a positive correlation between age and dental arch length of 8–10-year-old Javanese children in good nutritional status, especially in maxillary dental arch length.

Abstract Background: In fixed orthodontic therapy, maintenance of the original mandibular arch form is considered an essential factor for stability, moreover with the popular use of elastic archwires, and because its shape cannot be easily altered, the pre-determination of mandibular arch form becomes very important for each patient. The purpose of this study is to analyze the mandibular dental arch forms of Sudanese adults with normal occlusion and provides an easy method for orthodontists to determine different types of arch form. Methods: This Descriptive analytical, cross-sectional study determined the mandibular arch in a sample of 104 Sudanese university students. Measurements were done in the mandibular dental cast. Three arch widths and three arch lengths measurements were established and five ratios were determined. Analysis of arch form was done according to Raberin’s polynomial method. Results: The mid arch form was the most prevalent (75%), followed by narrow arch form (11.54%), wide arch form (6.73%), and pointed arch form (6.73%). There were no cases in flat arch form. Conclusions: In Sudanese subjects, four types of arch form were recognized. Norms of transverse and sagittal dimensions of the mandibular arch to determine types of the mandibular arch form in Sudanese orthodontic patients become available.

Malocclusion is defined as an irregularity of the teeth or a mal relationship between the dental arches beyond the range of what is accepted as normal. It has large impact on individual and society in terms of discomfort, quality of life and social and functional limitations. The etiology of malocclusion may be genetic, environmental or more commonly a combination of them. To determine the prevalence of malocclusion in children aged 8–12 years in the village of Zakigonj, Sylhet district A cross sectional descriptive survey was conducted among rural area (374) school- age children of Sylhet Zakigonj Upazila in Bangladesh. A total of 374 children aged 08-12 year old was examined for Class I, Class II, Class III molar relationship, increased over jet, increased over bite, open bite, crowding, cross bite and spacing after obtaining the written consent from the students, legal guardians and school authorities. The majority 173(70.0%) patients were found malocclusion in age <10 years and 89(70.1%) in age >10 years. Majority 121(69.9%) participants were found Angle’s class I in age <10 years and 75(84.3%) in age >10 years. One hundred six (61.3%) patients were found crowding of malocclusion in age <10 years and 67(75.3%) in age >10 years group. Which were not statistically significant (p<0.05) but increased overjet, open bite, cross bite and spacing were not statistically significant (p>0.05) between two groups. The results suggested that there is increased prevalence of malocclusion among children in the 8–12 years age group. The observation of this study will provide baseline data for implement early interceptive treatment for the elimination of factors inhibiting dental arch development as well as skeletal jaw growth.

ABSTRACT Introduction: Palatal rugae complete its development during early intrauterine life, whereas dental malocclusions in permanent dentition establishes several years into the post-natal life. Objective: The objective of present study was to determine if there is an association between the palatal rugae pattern and Angle’s classes of malocclusion. Methods: A cross-sectional study was conducted on pretreatment dental casts of 184 patients. The sample was divided into the following groups: Class I, Class II div. 1, Class II div. 2, and Class III. The number of palatal rugae was recorded, bilaterally. The length, pattern and orientation of three anterior-most primary rugae on both sides were recorded. Results: The mean age of the study sample was 17.8 ± 5.4 years. The mean number of the palatal rugae was 11.18 ± 2.5, with significant differences among different malocclusion groups. The length of the first rugae on left side and third rugae on both sides varied significantly among the groups (p< 0.05). Similarly, the pattern of palatal rugae was also found to be significantly different among the malocclusion groups. The right sided rugae did not have any significant difference in the orientation in different malocclusion groups; however, the left sided rugae showed significant differences among the four malocclusion groups (p< 0.001). Conclusions: The current study showed subtle differences in the palatal rugae pattern among the Angle’s classes of malocclusion. Similarly, the length and orientation of some rugae were also found to be significantly different between malocclusion groups.

Dental Arch Width

Aim: Objectives: To analyze variations in dental arch width in relation to oral habits.   Materials and Methods : Cross sectional  study was carried out Department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka with a total number of 600 primary school children of 3-6 years ages of Bangladeshi population. Results: This study was a cross sectional study conducted among the 600 children with 3-6 years old prima- ry school children of Bangladeshi population. According to present study, bottle feeding causes significant reduction in maxillary intercanine width and mouth breathers show significant reduction of both arches. Conclusion: It was observed that the children who had used a bottle had a significant reduction in maxillary intercanine width. Breathing through mouth appeared to be associated with a reduction in the size of both arches. This was more significant in the maxillary intercanine , mandibular  intercanine and mandibular molar widths. Therefore to prevent malocclusions, the public should be informed of the harm caused by certain oral habits, the benefits of breast-feeding, and the need to correct bad habits at early life.

Background: The palatal rugae are special constructions that are inalterable in their position and pattern during the lifestyles of an individual. This imparts them an exceptional role in the forensic dentistry and may play potential role in malocclusion identification. This study was aimed to see association of rugae pattern with sagittal skeletal malocclusion in orthodontic patients visiting tertiary care hospital. Methods: This cross-sectional examination was completed on pretreatment records (lateral Cephalometric radiographs and maxillary dental casts) of 384 subjects at the orthodontic department of Ziauddin Dental Hospital, Karachi. The study duration was from January to July 2019. The samples were sub-divided into three sagittal skeletal groups based on ANB angle proposed by Steiner’s on lateral Cephalometric radiographs (Class I with ANB angle between 0° to 4°; Class II: ANB angle greater than 5°; Class III: ANB angle less than 0°). The shapes of three most-anterior primary rugae were then evaluated bilaterally using Kapali et al., Classification. Chi Square test was applied to find association of rugae pattern among sagittal skeletal malocclusions groups. Results: Circular and curved rugae shapes were the most prevalent in all skeletal malocclusions. The primary palatal rugae pattern was seen to be significantly different among three skeletal malocclusion groups (p<0.05). The right and left sided palatal rugae pattern showed significant difference in all three skeletal malocclusion groups (p<0.05). Conclusion: The present study showed no specific palatal rugae pattern associated with sagittal skeletal malocclusion. Further studies on larger sample and use of modern 3D technologies to scan the maxillary casts are required for results that are more precise.

Abstract Background SARS-CoV-2 and HIV disproportionally affect underrepresented ethnoracial groups in the US. Medical mistrust and vaccine hesitancy will likely impact acceptability of SARS-CoV-2 vaccines. This study examined SARS-CoV-2 vaccine hesitancy among underrepresented ethnoracial groups with HIV and identified factors that may reduce vaccine uptake. Methods We conducted a cross-sectional study of adults ≥18 years with HIV residing in Miami, FL. Participants were invited to participate in the ACTION (A Comprehensive Translational Initiative on Novel Coronavirus) cohort study. A baseline survey was administered from April-August 2020 and followed by a COVID-19 vaccine hesitancy survey from August-November 2020. The COVID-19 vaccine hesitancy survey was adapted from the Strategic Advisory Group Experts survey. Comparisons by race and ethnicity were performed using the Freedman-Haltmann extension of Fisher’s exact test Results A total of 94 participants were enrolled, mean age 54.4 years, 52% female, 60% Black non-Latinx, and 40% non-Black Latinx. Black non-Latinx participants were less likely to agree that vaccinations are important for health when compared to non-Black Latinx (67.8% vs 92.1%, p=0.009), less likely to agree that vaccines are effective in preventing disease (67.8% vs 84.2%, p=0.029), less likely to believe that vaccine information is reliable and trustworthy (35.7% vs 71.1%, p=0.002), and less likely to believe vaccines were unnecessary because COVID-19 would disappear soon (11% vs 21%, p=0.049). Conclusion Medical mistrust, vaccine hesitancy and negative sentiments about SARS-CoV-2 vaccines are prevalent among underrepresented ethnoracial groups with HIV, particularly Black non-Latinx. Targeted strategies to increase vaccine uptake in this population are warranted.
