Abstract

Introduction: Root canal treatment is done to maintain the teeth to last as long as possible in the oral cavity. This can be done with three main stages, such as biomechanical preparation, sterilization and root canal filling. The hermetic seal of root canal filling has an important role in the success of root canal treatment. Objective: The aim of this in-vitro study is to compare the microbial leakage of root canals filled with RealSeal sealer/Resilon Points and AH Plus sealer/conventional gutta-percha points using single cone obturation technique and warm vertical compaction technique. Methods: Thirty-two extracted human mandibular premolars with single canals were decoronated to a standardized root length of 15 mm and prepared using crown-down technique to a master apical file size 30/.09. Teeth were divided into four experimental groups (n = 7 each group) and controls (n = 1 each group). Teeth in the first group were obturated using single master gutta percha cone and AH Plus sealer and second group were obturated with single Resilon gutta percha cone using RealSeal sealer. Third experimental group was filled with warm vertical condensed gutta-percha using AH Plus sealer and fourth group was filled with warm vertical condensed Resilon gutta-percha using RealSeal sealer. The coronal chamber of each sample were inoculated with Enterococcus faecalis. Results: There were no significant differences between the four experimental groups (P = 0.182). The differences occurred only in the survival time from each group. Group 4 (Warm Vertical Condensation - RealSeal) has the lowest leakage rate among other groups and the fastest leakage occurred in group 1 (Single Cone - AH Plus). Conclusion: The single-cone techniques does not insure durable apical seal against bacterial leakage. Warm vertical compaction technique using Resilon gutta-percha and RealSeal sealer appears to be more effective in minimizing bacterial leakage than gutta-percha and AH Plus sealer.

Abstract

Background : Fractures are the most undesirable thing in endodontically treated teeth. The main reason in endodontically treated teeth has a considerable risk for fractures is the loss of tooth structure. Objective : This study aims to determine the effect of access cavity preparation and instrument taper percentage on upper premolar fractures. Material and Methods : Twenty-four upper premolar samples were stored in sterile saline solution. The sample was divided into 2 large groups which were then divided into two groups for each group by random allocation. Twelve contracted endodontic cavity (CEC) preparations and the remaining twelve samples using traditional endodontic cavity (TEC) techniques. Each group was prepared with 6 samples 4% taper instrumentation and 6 samples 8% taper instrumentation. Each sample was irrigated with 5 ml of NaOCl. After that, the sample is tested using a universal testing machine. Result : The CEC group showed a significant reduction in fracture rates compared to the TEC group (p <0.05), but there was no significant difference in the fracture in the tapering instrumentation (p> 0.05). Conclusion : Preparation with the concept of minimally invasive CEC provides better resistance to fractures in the upper premolar while tapering instrumentation does not affect the fracture of the upper premolars.

Abstract

The impact of the Covid-19 has made the elderly's access to dental and oral health even more limited. Oral hygiene in the elderly living in nursing homes is often ignored so it falls into the poor category. The high prevalence of caries and other dental problems makes the elderly need more dental treatment. Poor oral health can lead into systemic or local infections that will affect general health, especially in the elderly who have impaired physiologic or pathologic function. Increased knowledge will improve their oral hygiene. Therefore, to increase members' knowledge and awareness to oral health, FKG Trisakti held an education to maintain their oral health and dentures. Pre and post tests are given to the participants to determine the success of the education. T test result showed increase in knowledge from participants before and after giving the material. Further training can be given to caregivers as they were there to help the elderly maintain their oral care.

Abstract

The COVID-19 pandemic poses the challenge ofining a healthy and varied diet and regular physical activity. This is because people prefer to buy processed foods, such as snacks, fast food, and ready-to-eat cereals, which tend to be high in fat, sugar, and salt. In addition, psychological and emotional responses to the outbreak of COVID-19 can increase the risk of developing dysfunctional eating behavior. The choice of foods and how often they are eaten can affect the health of the body, teeth, and gums. Excessive consumption of sugar-containing soda, fruit drinks with added sugar, or low-nutritional snacks can increase the risk of teeth hole. Therefore, a community service program (PkM) was designed with the aim of providing education and training to the community to gain knowledge about diet and improve health. The development and training of a healthy diet to the Lisiuex Apartment Meditarenia 1 West Jakarta community was conducted online, illustrating the improvement of the participants' knowledge and yielding good results. Sustainable education and training programmes are needed as a means of improving the development of health that starts with the family.

Abstract

Background: The very rapid development of technology for aesthetic treatment results has given rise to composite resin namely one shade composite resin. One shade composite resin has a chameleon effect that can copy all tooth colors using just one color. However, this composite resin can change color which causes patient dissatisfaction with the treatment results because it interferes with aesthetic value and appearance. This color change is influenced by the presence of color pigments and the acidic pH in the food and drinks, specifically red wine. Objective: To examine the effect of red wine consumption on the color stability of one shade composite resin. Methods: This research used sixteen one shade composite resins, consisting of 2 different brands in cylindrical shape (diameter: 10 mm; height: 2 mm) and allocated to 2 different groups, that is the control and treatment groups for each type of composite resin. Control groups were immersed in artificial saliva fo 6 days within 144 hours. Treatment groups were immersed in red wine for 4 days within 96 hours, followed by immersion in artificial saliva for 2 days within 48 hours. Color measurements were measured using vita easyshade V. Results: The ANOVA Two Way results showed that there were significant color change (p<0,05). Conclusion: There is an effect of immersion red wine on the color stability of one shade composite resin.

Abstract

Obliterasi saluran akar adalah kondisi yang ditandai dengan deposisi jaringan keras dalam ruang saluran akar yang sering kali disebabkan oleh trauma dan dapat menyebabkan tantangan besar dalam diagnosis maupun perawatan. Seorang wanita berusia 27 tahun dengan keluhan diskolorasi kuning pada gigi insisivus sentral atas (gigi 11) akibat trauma 10 tahun sebelumnya. Pemeriksaan klinis dan radiografis menggunakan CBCT menunjukkan obliterasi saluran akar tanpa disertai kondisi patologis periapikal. Uji sensitivitas pulpa menunjukkan tidak ada respons, namun tidak dapat disimpulkan sebagai nekrosis. Untuk manajemen, static guide endodontik berbasis data CBCT digunakan untuk membantu penetrasi akurat ke saluran akar yang terkalsifikasi. Perawatan melibatkan preparasi biomekanik dengan teknik crown down menggunakan instrumen rotary, irigasi larutan natrium hipoklorit, dan medikasi intrakanaldengan kalsium hidroksida. Saluran akar kemudian diobturasi menggunakan teknik single cone dengan bioceramic sealer. Untuk memulihkan estetika, dilakukan perawatan intracoronal bleaching dengan hidrogen peroksida 35% yang dilanjutkan dengan restorasi komposit. Prosedur ini berhasil mengembalikan warna gigi dari warna A3 menjadi A2 tanpa komplikasi teknis seperti perforasi atau patahnya instrumen. Evaluasi menunjukkan jaringan periapikal dalam batas normal tanpa gejala klinis. Laporan ini menunjukkan bahwa penggunaan static guide endodontik meningkatkan akurasi dan efisiensi dalam pengelolaan kasus obliterasi saluran akar, terutama pada gigi anterior dengan diskolorasi yang menuntut estetika. Pendekatan ini direkomendasikan sebagai solusi yang efektif untuk kasus serupa, mengatasiketerbatasan teknik konvensional dan meningkatkan keberhasilan jangka panjang.
