Abstract

First permanent molar mandible had already errupted in  6-7 years old and the root formation completes at age of 9-10 years. The root formation of first permanent mandible starts at 5 years and 3 months old, which in radiograph shows as radiopaque area that appear below the crown line, and the root development become half of the root formation at 6 years and 2 months old. This stage of first permanent mandible root development can be associated with age estimation. The aim of this study was to determine the stage of the root development, the shape and lenght of the first permanent molar mandible in children aged 6-10 years old in periapical radiograph. The radiograph was placed on the viewer box and marked the edge of cemento enamel junction and the tip of apex root by pencil and placed the tip of calipper on the two point that have been marked then measured the leght using a ruler. Measurement of the roots length were taken for mesial and distal of each tooth and noted the root shape that assessed form the radiograph. The result of this study shown that the lenght of first permanent mandible of 6-10 years old was in the range of 5,5 -14 mm for mesial root an 4,5 – 12 mm for distal root. The majority of root development shape was at stage R ¾ at 6 years (71,4 %), at 7years (100 %), at 8 years (85,7%) and at the age of 9 years old 85,7% of root shape was at stage Rc and 57,1 % of the rooot shape of the 10 years old was at stage Ac, which stage means the root formation already complete. As a conclusion, the mesial root length appears longer than the distal length with the root lenght varies on the age of 6-10 years old. The root development shape of 6 and 7 until 8 years old mostly shows the root already formed ¾ of root formation, then at 9 years old the root shape become complete but the apex not yet, and at 10  years  old the stage of the root shape already complete which shown by the closed of the root apex completly.

Abstract

Periodontal ligaments are one of the supporting tissues of teeth that undergo remodeling during the tooth movement process. Vitamin C deficiency inhibits the regeneration of collagen fibers, which are important in tissue remodeling that affects the widening of the periodontal ligament space during the process of tooth movement. The widening of periodontal ligament space can be seen by taking radiographic photos. The purpose of this study was to determine the width of the periodontal ligament space of guinea pigs by administering vitamin C, without vitamin C, and the differences between the two groups. Those samples were grouped into four groups with observation times of 1, 4, 7, and 10 days, and each group consisted of the control group and vitamin C group. Those samples were paired with orthodontic separator rubber. After the specified time was completed, periapical radiographs were taken, and the width of the periodontal ligament space was measured by using Image J software. The mean width of the periodontal ligament space in the vitamin C group was smaller than the control group. Based on this study, it can be concluded that vitamin C has an effect on reducing periodontal ligament space in the process of tooth movement. Key words: periodontal ligament space, vitamin C, tooth movement, remodeling

Abstract

Objectives: Biomechanical behavior analysis of the periodontal ligament (PDL) under various loading conditions is essential for understanding the impact of occlusal force distribution. A comprehensive understanding of this aspect is fundamental, and radiographic examination is a crucial modality for evaluating periodontal health. This review aims to illustrate the role of radiographic examination in influencing dental prognosis through the use of Finite Element Analysis (FEA) to assess occlusal load and stress distribution in PDLs. Review: Radiographic imaging techniques are critical for assessing the extent of occlusal trauma and its impact on the periodontal ligament and surrounding structures. Modalities such as conventional radiography, cone-beam computed tomography (CBCT), and micro-computed tomography (micro-CT) are commonly used to evaluate occlusal load. Studies have demonstrated that a balanced occlusal scheme results in a more uniform stress distribution, while an unbalanced scheme leads to localized stress concentrations, increasing the risk of periodontal damage. FEA has emerged as a powerful tool for simulated and visualizing stress patterns in the PDL and quantitatively calculating stresses and deformations in the periodontium. Technological advances in imaging, when applied in conjunction with finite element computational techniques, have shown that oblique loading results in higher stress concentrations compared to vertical loading, particularly in the PDL of mandibular first molars. These higher stresses, often observed in the cervical and apical regions, highlight the potential for more significant PDL damage, making it useful for evaluating bone loss and PDL integrity. for eligibility and completeness of journals. Conclusion: Integration of advance radiographic imaging with FEA has significantly enhanced the understanding of occlusal load and stress distribution in the periodontal ligament. This advancement has propelled the field of periodontal biomechanics, offering very valuable insights into PDL’s biomechanical behavior as it responds to varying occlusal loads, to optimize outcomes in periodontal and orthodontic care.

Abstract

Health is very important to always pay attention to. Healthy behavior can affect the health of everybody. Dental and oral health is a part of general health, and to keep teeth and mouth healthy can be done with the right techniques and ways to brush teeth. Based on Basic Health Research, dental and oral diseases still occur in North Sumatra province, both urban and rural. Therefore, through the Community Service Institution at USU, a community service activity was carried out under the title Improvement of Dental and Mouth Health through the Counseling for Dental and Oral Health Care for Children of Melati Aisyiah SLB Orphanage Homes in Bandar Khalifah. This activity is based on the need to maintain oral health from an early age so that good behavior in maintaining health can be accustomed from childhood. In addition, there are only a few orphanage children who realize correctly the importance of dental health for general health. Counseling on the maintenance of dental and oral health in children of the SLB Melati Aisyiyah Orphanage, Bandar Khalifah can provide a deep understanding of the importance of maintaining oral health by brushing teeth early on.
