Abstract : Background: Several treatment options have been proposed for the management of impacted molars, such as surgical extraction, transplantation, surgical uprighting, or orthodontic uprighting Aim: This study aimed to compare the ramus bone thickness and depth between two different vertical facial types to detect the safety length of mandibular ramus miniscrews. Methods: In this study ramus thickness and depth was measured by using Unidentified Cone-beam Computed Tomography scans of 40 subjects they were classified according to vertical facial type into 2 equal groups (norm divergent and hypo divergent). Ramus thickness was measured as the distance from the outer (buccal) to the inner (lingual) aspects of the mandibular ramus. Ramus depth was measured as the distance from the anterior border of the ramus to the inferior alveolar nerve canal. The measurements for ramus thickness and ramus depth were performed at 3 different levels: Occlusal plane (OP), five mm above the (5 OP) and ten mm above the occlusal plane (10 OP). Results: Regarding thickness: non-significant difference was found between both groups at the same level while significant difference between two different levels at the same group was recorded. Regarding depth: non significant difference was found between all groups at five mm above the occlusal plane and ten mm above the occlusal plane while significant difference was found between normodivergent group and hypodivergent group. Conclusion: The optimal insertion s

Abstract : Indonesia as a developing country is always facing various infectious and non-communicable diseases, including Maluku Province, especially East Seram District. The purpose of the following research was to identify factors related to community knowledge about leprosy in East Seram District. Data were obtained from a household health survey conducted in September-December 2023 in East Seram District, involving 253 respondents. Logistic regression analysis was used to determine the factors that impact on people's knowledge of leprosy. We found that most respondents had a low level of knowledge about leprosy (83.4%). Those who graduated from elementary/junior high school or no school (OR=2.65, p=0.029), graduated from university (OR=6.93, p=0.003), came from households with a high wealth index (OR=5.11, p<0.001), and had visited a health worker (OR=2.77, p=0.010) had a high level of knowledge about the disease. This study suggests the need for health education programmes targeting individuals with less knowledge in East Seram. This study suggests the need for health education programmes targeting individuals with poor knowledge in East Seram District to improve knowledge and disease management.

Abstract : Background: Kocher’s criteria have been used for a long time as a screening tool in diagnosing septic arthritis of the hip. The study aimed to assess the clinical presentation and applicability of Kocher's criteria for diagnosing septic arthritis of all weight-bearing joints. Materials & Methods: This retrospective cross-sectional analytical study of septic arthritis in children <12 years was done by collecting all the necessary data from electronic medical records from January 2018 to December 2022. Results: In a total of 28 cases of arthritis, the knee joint was the most affected, at 14 (50%), followed by the hip at 11 (39.5%) and the ankle at 3 (10.7%). Kocher's modified criteria were applied to all three weight-bearing joints. Three of the five criteria appeared to be strong predictors for septic arthritis: non-weight bearing was seen in 26 (92.9%), and 25 (89.3%) of the cases showed raised erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels. Conclusions: Kocher’s criteria can be equally applied to all three major weight-bearing joints in diagnosing septic arthritis in contrast to only the hip joints, as mentioned in previous studies. Findings like the painful range of movements and an ultrasound investigation are important supplementary criteria for confirming the diagnosis.

Abstract : ABSTRACT Purpose: The objective of this study was to use the ABO-DI to assess the pre-treatment case complexity of the orthodontic clinic program of the Suez Canal University. Methods and material: The sample included 120 unidentified pretreatment casts and cephalometric and panoramic radiographic records that were selected and collected from the orthodontic clinic program of the Suez Canal University. The DI scores were categorized into three degrees of DI complexity, low, moderate, or high complexity according to the total DI score. Results: No significant associations were found of DI with gender. Patients with ABO-DI low score was (31.6%), moderate score was (36.6%), while (31.6%) of the total sample had a severe ABO-DI score. Angle classifications showed a significant positive correlation with malocclusion complexity, As the classes increase from I to III, the malocclusion complexity increases. Conclusions: The DI was a relatively reliable index for measuring malocclusion severity. All the registrars had most of their cases in the moderate category. The cephalometric parameter was the highest effect on DI score, and the lowest score was for lateral openbite.

Abstract : Introduction: Complete denture rehabilitation remains the most common solution for treating edentulism. 3D-printed dentures have evolved as a new treatment modality to decrease fabrication time, increase patient predictability, and be a cost-effective option compared to milled dentures. The study aimed to investigate the retention of 3D-printed dentures versus conventional heat-cured acrylic dentures. Methods: After calculating the sample size and obtaining ethical committee approval, twenty patients were recruited and randomly and equally divided into two groups: Group A received a conventional heat-cured acrylic denture, and Group B received printed complete dentures. Denture adaptation was measured. Results: The t-test shows a statistically significant difference between the two groups (p-value <0.05) Conclusions: This study's limitations allowed us to conclude that 3D-printed dentures showed better adaptation than conventional heat-cured acrylic dentures.
