ABSTRACT
This article presents a case study illustrating the successful management of skeletal Class III malocclusion in an adult through an orthodontic-surgical approach. The clinical case outlines the entire process, from initial assessment to post-treatment outcomes, conducted within our service. Key steps include diagnostic planning using advanced tools such as 3D imaging and virtual surgery simulation. Pre-surgical orthodontic treatment was carefully planned to prepare dental and skeletal structures for surgical correction. Orthognathic surgery was performed precisely according to the established plan, followed by a post-surgical orthodontic phase to finalize occlusion. Short-term and long-term outcomes are evaluated, highlighting significant improvement in facial aesthetics, occlusal function, and post-treatment stability. This case study demonstrates the effectiveness of our integrated approach in managing skeletal Class III malocclusions in adults, underscoring the importance of interdisciplinary collaboration for optimal outcomes.

ABSTRACT
Introduction: The periodontium is a complex system of supporting tissues and alveolar bone that surrounds and maintains the teeth in place. It is essential for oral health and functionality. Orthodontic treatment, aimed at correcting dental malpositions and improving occlusion, has a significant impact on the health and integrity of the periodontium. Currently, there is a constant increase in demand for orthodontic treatments, both in children and adults, with a variety of available appliances, fixed or removable. However, these devices can compromise dental hygiene and potentially lead to periodontal problems. Our work, based on a literature review, aims to discuss the effects of fixed and removable orthodontic treatments on periodontal health. Materials and Methods: The objective of this work is to present the adverse effects of orthodontic treatment on the periodontium through a bibliographic study on the two databases Google Scholar and PubMed. There are numerous epidemiological studies on the influence of fixed and removable orthodontic treatment on periodontal health. Conclusion: Throughout this work, we will explore the interactions between orthodontics and the periodontium, highlighting the physiological mechanisms and therapeutic implications that stem from these close relationships, with the primary goal being to minimize adverse effects on the periodontium during and after orthodontic treatment. By fully understanding these periodontal manifestations following orthodontic therapy, orthodontists will be better equipped to plan and execute orthodontic treatments that not only improve aesthetics and occlusal function but also preserve the long-term health of their patients' periodontium.

ABSTRACT
Understanding the intricate anatomy of the pulp cavity and the root canal system of dental organs is of utmost importance for dental practitioners. This knowledge and other clinical and theoretical considerations contribute to a surgical process with an almost perfect success rate. This literature review was conducted with the primary goal of enhancing this understanding. A comprehensive search was performed across multiple research databases, including Google Scholar, PubMed, and Scielo. This search encompassed articles with no restrictions on publication date due to the importance of some postulates and laws. This comprehensive review delves into the dental organ's intricate morphology, clinical divisions, the definitions, fundamentals, and classifications that have garnered widespread acceptance within the scientific community. These include the laws articulated by Krasner and Rankow, which pertain to the pulp chamber. Also, we examine Vertucci's classification, which provides insights into the diverse configurations of root canals. Furthermore, we scrutinize the nomenclature of Pucci and Reig, which systematically categorizes variations in the root portion of a tooth. Moreover, we emphasize the critical relevance of this knowledge to clinical practice. Each aspect is not an isolated concept but an integral part of the puzzle when performing a root canal treatment. By comprehending these intricate details, clinicians can make informed decisions, plan procedures more effectively, and execute a precise and successful clinical approach.

ABSTRACT
Background: Oral health problems affected 55.6% of adolescents aged 10-14 in Indonesia. This can be prevented by maintaining oral hygiene. Many physical and psychological changes happen in the adolescent phase, and more attention is needed to maintain oral hygiene. Oral hygiene is influenced by various factors, including demographic and socioeconomic factors. Objectives: This study aimed to determine factors associated with oral hygiene among adolescents in Jember, Indonesia. Method: There were 409 students from eight different junior secondary schools in Jember Regency as participants in this study. The sample was obtained using the cluster random sampling method. Data on oral hygiene as a dependent variable was collected through the OHI-S examination. Data on sex, school, ethnicity, mother and father education, father and mother employment, monthly income, and number of children as independent variables was gathered from questionnaires and students' data from the school database. First, a univariate Spearmen test was run for all independent variables (p<0.05). The significant variables were then analyzed using multiple regression to determine factors associated with oral hygiene (p<0.05). Results: The average OHI-S score was 2.53, which was categorized as moderate. Multivariate analysis results showed that females were more likely to have better OHIS-S scores than males (B=-0.716; p=0.000); ethnic Javanese were more likely to have better OHI-S scores than Maduranese (B=0.293; p=0.004); and middle-income students more likely have better OHI-S than low-income students (B=-0.307; p=0.003). Conclusion: It can be concluded from this study that adolescents' socioeconomic background is associated with their oral hygiene. This suggests the need to give more attention to a new model of oral health promotion programs targeting gender, ethnicity, and lower-income groups.

ABSTRACT
In the last decade, recent advancements have been made in the field of orthodontics. With the development of newer advances such as artificial intelligence, the use of robotics, auto-transplantation, newer materials, newer drugs, and genetics in clinical practice, the clinical care of patients has improved significantly. Such remarkable advancements have been achieved in the diagnostic tools, technological, material, imaging, as well as treatment aspects of dentistry and have become the new paradigm of orthodontics. Moreover, three-dimensional (3D) imaging systems such as Cone Beam Computed Tomography (CBCT) have become an invaluable asset for diagnosis and treatment planning. In this article we discuss different advancements in the field of orthodontics.

ABSTRACT
Amelogenesis imperfecta (AI) is a genetically inherited disorder characterized by defective enamel formation, posing a significant challenge in esthetic treatment for clinicians. The choice of an appropriate treatment modality is largely dictated by the specific type of AI. This paper aims to elaborate on therapeutic options available for patients under 18 with amelogenesis imperfecta, emphasizing a multidisciplinary treatment approach.

ABSTRACT
The aim of the study was to compare and evaluate fracture resistance of Custom Cast post and core, Pre-fabricated post and core and CAD/CAM fabricated post and core. Material and Methods: 60 transparent endoblocks with single root canal that simulated natural teeth were randomly divided into 3 groups of 20 endoblocks each. The working length of the root canal in the transparent endobloc was determined. The canals were prepared with K-file sizes 10,15 and 20 followed by Protaper Ni-Ti files (sizes S1, S2, F1 and F2); Dentsply by using the crown down technique to the full working length. Gutta percha was removed from the root canals with Peeso drills to a depth of 12 and post spaces were prepared in all groups with the special preparation drills of each system leaving 5mm of gutta percha in all specimens. For group 1, after root canal treatment of 20 samples, Prefabricated plastic burnout posts were coated with pattern resin and then inserted into the canal with slight pressure to take the canal impression which was further send for casting followed by using GC gold label glass ionomer resin for luting. For group 2, the Prefabricated EDELWEISS post and core were placed into the canal and the cement was allowed to set. For group 3 impression of the canal was made using pattern resin. The burnout post was scanned with a lab scanner and designing was done using the designing software. CAD-CAM fabricated post and core was placed into the canal and luted with the help of glass ionomer cement. Composite core fabrication was done and the specimens were secured in a universal load-testing machine at an angle of 1300 to the long axis of the tooth. Until fracture occurred, a compressive force was applied at a crosshead speed of 1 mm/min. The fracture loads were determined. Mean failure load for each group was recorded in N. Results: The mean fracture load of Group 1, was found to the maximum followed by Group 3 & Group 2 samples, in decreasing order. Conclusion: The mean ......
