Abstract

Introduction: Aesthetics smile is a crucial aspect of physical appearance that significantly influences self-confidence. The proportion of maxillary anterior teeth size plays an essential role in forming a harmonious smile. The Smile Index serves as a parameter to measure smile characteristics from the frontal dimension.Aim: to determine the relationship between the maxillary anterior teeth size ratio and Smile Index in orthodontic patients at the FKG UB Clinical Laboratory.Methods: This cross-sectional analytical study utilized 32 samples of study models and photometry from orthodontic patients aged 17-30 years who met the inclusion criteria. The anterior teeth size ratio (central incisor, lateral incisor, and canine) was measured using calipers on study models by dividing mesiodistal width by cervicoincisal height. The Smile Index was measured through frontal photometry by dividing intercommissural width by interlabial distance during smiling. Data were analyzed using the Spearman correlation test and simple linear regression with a 95% confidence level.Result: The mean size ratio was 0.88±0.02 for central incisors, 0.87±0.02 for lateral incisors, 0.93±0.02 for canines, and 6.98±0.25 for Smile Index. There was no significant difference between right and left anterior teeth size ratios (p>0.05). Correlation tests showed no significant relationship between central incisor size ratio and Smile Index (r=-0.83; p=0.651), lateral incisor (r=0.33; p=0.858), or canine (r=-0.79; p=0.667). Overall, the anterior teeth size ratio showed no significant relationship with Smile Index (p=0.908).Conclusion: There is no relationship between the maxillary anterior teeth size ratio and Smile Index in orthodontic patients. Anterior teeth do not show a significant relationship either individually or collectively with Smile Index values. This finding suggests that smile aesthetics could be influenced by multiple factors beyond tooth dimensions alone, including soft tissue characteristics and facial proportions.

Abstract

Introduction: Digital dental technologies have been proposed as alternatives to conventional casts for the creation of ante-mortem (AM) records in forensic identification. However, their accuracy and forensic applicability require systematic evaluation. Aim: This systematic review evaluated original research on intraoral scanners, CAD/CAM systems, and AI-assisted technologies for generating ante-mortem (AM) dental records and their potential forensic applicability, with emphasis on dimensional accuracy, reproducibility, advantages, and limitations. Review: The literature search was conducted through two major scientific databases, namely Google Scholar and PubMed, to identify relevant studies on digital dental records in forensic contexts. The search strategy was developed using structured keyword combinations related to forensic dentistry, digital dental records, intraoral scanners, CAD/CAM systems, and artificial intelligence. The inclusion and exclusion criteria were determined using the SPIDER framework, which consists of Sample (S), Phenomenon of Interest (PI), Design (D), Evaluation (E), and Research Type (R), to ensure that the selected studies were relevant to the objectives of this review and aligned with the research questions. Conclusion: Existing studies demonstrate that digital dental technologies provide high morphometric accuracy, with three-dimensional deviations remaining within clinically acceptable ranges. STL-based comparisons, surface deviation mapping, and three-dimensional superimposition offer objective analytical approaches that show strong potential for forensic application. However, direct validation under simulated forensic conditions remains limited, and further research is required before full implementation in forensic practice.

Abstract

Introduction: Thermoplastic nylon is a flexible denture base material known for its excellent esthetics, making it a viable alternative for patients allergic to residual monomers or metals. However, its high water absorption rate may compromise color stability, a critical property for clinical longevity. Robusta coffee, a widely consumed beverage in South Sumatra, contains high concentrations of chromogenic agents that potentiallly induce significant staining. Aim: This study aimed to evaluate the effect of robusta coffee immersion and duration on the color stability of thermoplastic nylon denture base. Methods: This laboratory experimental study employed a pretest–posttest control group design. Thirty-two thermoplastic nylon specimens (20 × 3 mm) were divided into eight groups (n=4) and immersed in either robusta coffee or distilled water for 1, 3, 5, and 7 days. Color changes were quantified using a colorimeter. Data were analyzed using paired t-test, one-way ANOVA, and post hoc LSD tests ). Result: The paired t-test revealed significant changes in lightness (∆L) accross all groups(p<0.05. The highest mean color change (∆E) occurred in the 7-day robusta coffee immersion group (mean = 14.25), while the lowest was observed in the the 1-day distilled water group (mean = 9.68). Conclusion: Immersion in robusta coffee significantly affects the color stability of thermoplastic nylon. Furthermore, increased immersion duration correlates with a higher degree of discoloration.

Abstract

Introduction: Malocclusion is a condition characterized by misalignment of the teeth and improper jaw alignment, which can lead to impaired chewing function. One type of orthodontic appliance that can be used in the treatment of malocclusion is the removable orthodontic appliance. This appliance offers the advantage of being easily removed and reinserted by the patient, thereby helping to maintain better oral hygiene, and carries a lower risk of root resorption and periodontal complications compared to fixed orthodontic appliances. Research on changes in alveolar bone height has largely focused on the use of fixed orthodontic appliances, while studies on removable orthodontic appliances remain limited. Aim: This study aims to evaluate the differences in alveolar bone height before and after the use of removable orthodontic appliances in patients at Unimus Dental Hospital. Methods: This study applied an analytical observational approach with a cross-sectional design. The study was conducted by measuring the alveolar bone height on panoramic radiographs before and after the use of removable orthodontic appliances on 10 teeth in 17 subjects using ImageJ® software. Result: The results of both the paired sample t-test and the Wilcoxon signed rank tests showed p-values greater than 0.05. Conclusion: There was no difference in alveolar bone height before and after the use of removable orthodontic appliances in patients at the Unimus Dental Hospital Keywords: alveolar bone, bone resorption, removable orthodontic appliances
