Aim: To evaluate the effect of print orientation (0°, 45°, and 90°) on the dimensional accuracy, precision, and production parameters of three-dimensional (3D) printed complete denture models fabricated using VAT photopolymerization and fused deposition modeling (FDM) technologies. Settings and Design: An in-vitro experimental comparative study was conducted to analyze orientation-dependent variations in dimensional trueness and precision among denture models fabricated with two additive manufacturing systems. Materials and Methods: A complete denture prosthesis STL file was fabricated in 60 samples using VAT photopolymerization and FDM technologies across three orientations (0°, 45°, and 90°). Printed models underwent postprocessing, followed by digital superimposition to evaluate trueness and precision. Statistical Analysis Used: Statistical analyses were performed using one-way ANOVA with post hoc Tukey’s honestly significant difference tests and independent t-tests for intertechnology comparison. Results: VAT prints demonstrated higher average accuracy (mean deviation: 0.1106 mm) but greater variability (standard deviation [SD] =0.2448 mm) than FDM (mean deviation: 0.0316 mm, SD = 0.1558 mm). Across both technologies, the 0° orientation showed the least deviation (VAT: 0.1106 mm and FDM: 0.0316 mm). ANOVA indicated no significant differences among orientations (P = 0.109), whereas t-tests revealed substantial differences between technologies (t = 16.46, P < 0.00001). FDM at 90° exhibited the lowest variability (SD = 0.1163 mm), suggesting a trend toward improved consistency, though this did not reach statistical significance. Conclusion: Print orientation influenced dimensional accuracy trends, but only technology type showed statistically significant differences. VAT photopolymerization is suitable for high-precision applications.

Maxillary sinus mucoceles are rare, benign, and expansile lesions that can lead to gradual enlargement and bony erosion. When a mucocele becomes infected, it is termed a mucopyocele or pyocele and can closely mimic odontogenic pathologies. We report the case of a 38-year-old male presenting with pain and swelling in the maxillary posterior region, mimicking a radicular cyst. Accurate diagnosis relies on a combination of symptoms, clinical evaluation, imaging, surgical exploration, and histological confirmation. This case highlights the clinical overlap between sinus mucopyoceles and odontogenic lesions, emphasizing the importance of a comprehensive diagnostic approach.

INTRODUCTION:An increase in dental trauma due to seizures in epileptic patients is a serious concern. Other serious injuries are treated immediately, but dental trauma goes ignored. We conducted a systematic review and meta-analysis to know the proportion of dental injuries and their subgroups. METHODS:We searched PubMed, EMBASE, Web of Science, and Google Scholar from January 1, 1990, to April 30, 2023, to identify articles reporting dental trauma due to epilepsy. We used two measures of heterogeneity (Q and I2-statistic) to select appropriate model (fixed or random effect model) for estimating pooled proportion. We used meta-regression to identify the significant predictors affecting the proportion of interest. RESULTS:We included 28 articles in the final meta-analysis. The pooled proportion (prop) of dental trauma in epilepsy patients was 0.20 (95% CI 0.16 to 0.25). The categories for subgroup meta-analysis were hard tissue dental injury (prop: 0.14 (0.09, 0.20)), soft tissue dental injury (prop: 0.25 (0.18, 0.32)), both groups (prop: 0.48 (0.39, 0.57)), injury to teeth (prop: 0.14 (0.09, 0.20)), injury to tongue (prop: 0.28 (0.18, 0.37)), injury to lip (prop: 0.17 (0.10, 0.25)). gum injury (prop: 0.09 (0.05, 0.16)), injury to cheek (Prop: 0.12 (0.06, 0.18)), others (Prop: 0.61 (0.46, 0.75)), Negroid group (prop: 0.15 (0.08, 0.21)), Caucasian group (prop: 0.20 (0.12, 0.28)), and Asian group (prop: 0.24 (0.16, 0.32)). CONCLUSION:The proportion of traumatic dental injuries due in patients with epilepsy was 0.20. Oral soft tissues were more affected than hard tissues (prop: 0.25 vs 0.14), and among soft tissues, tongue was most affected (prop: 0.28). Early age of epilepsy onset and high frequency of seizures also contribute to dental trauma.

Maxillofacial fractures are common in trauma units globally, often requiring Maxillo-Mandibular Fixation (MMF) for several weeks. While MMF aids in bone healing, it restricts mandibular movements, impacting functions like eating and speaking, potentially leading to reduced nutritional intake and compromised health. Our study aims to assess the impact of nutritional intervention on the physical health of patients during MMF for jaw fractures by monitoring changes in weight and midarm circumference at various treatment intervals. 144 patients with jaw fractures reported to the Oral and Maxillofacial Surgery Department of Govt. Dental College, Calicut who require maxillomandibular fixation were included irrespective of the etiology and assigned into two groups based on randomization-nutrition intervention group [GROUP 1] and nutrition nonintervention group [GROUP 2]. Anthropometric parameters such as body weight, midarm circumference were measured. Group 1 patients (Intervention group) had significantly reduced weight loss compared to group 2 (nonintervention group) at fourth week interval. MAC remained almost stable in group 1 and had a significant reduction in group 2. Individually assessed and planned nutrition intervention may effectively help patients to maintain their weight and nutritional status during the MMF period, thus providing the patient with an improved quality of life.
