Lesi periapikal adalah lesi yang berada di daerah apikal dan dapat dirawat dengan perawatan endodontik untuk mencapai penyembuhan. Proses penyembuhan lesi periapikal dapat dievaluasi dengan pemeriksaan radiografis dengan menggunakan radiograf periapikal. Tujuan penelitian ini adalah untuk mengetahui perubahan gambaran yang terjadi pada proses penyembuhan lesi periapikal pada radiograf periapikal menggunakan software ImageJ. Metode: Metode penelitian ini merupakan penelitian deskriptif yang menggunakan 30 arsip radiograf periapikal pada saat diagnosis, pengisian, dan kontrol perawatan endodontik yang terdapat di Instalasi PPDGS Konservasi Gigi RSGM Unpad. Proses penyembuhan ini dilihat dari luas dan densitas lesi dengan menggunakan software ImageJ. Hasil: Nilai rata-rata pengurangan ukuran luas lesi sebesar 13,25±10,77 mm2 dan peningkatan densitas rata-rata sebesar 9,95±7,26% yang dilihat dari foto diagnosis, pengisian, dan kontrol. Simpulan: Gambaran penyembuhan lesi periapikal terjadi pengurangan ukuran luas lesi terbesar pada tahap diagnosis ke pengisian dan peningkatan densitas terbesar pada tahap pengisian ke kontrol pada perawatan endodontik yang dilihat dari radiograf periapikal menggunakan software ImageJ.

Indonesia is one of many developing countries with high caries prevalence which needs more attention regarding the countermeasures as well as the preventive treatment. Dental problems or pulp injury was able to treated with an endodontic procedure such as pulpotomy. The success of the mummification treatment was able to evaluated through subjective and objective examinations. The purpose of this study was to describe an evaluation of the mummification treatment at Conservative Dentistry Clinics of Faculty of Dentistry Universitas Padjadjaran by examining the condition of the teeth that have received mummification treatment. This study was a descriptive study with purposive sampling technique. The number of samples was as much as 38 teeth from patients who have completed mummification treatment. The results showed the success of mummification treatment was as much as 67% in less than three months, 44% in the range of time 3-6 months, and 29% in more than 6 months. The conclusion of this study was the mummification treatment success at Conservative Dentistry Clinics of Faculty of Dentistry Universitas Padjadjaran was high in less than three months and decreasing in more than six months after treatment.

Introduction: Irrigation of the root canal is an important part of the endodontic treatment. Root irrigation technique can be done with the manual and sonic system by using 2.5% NaOCI solution. Calcium hydroxide [Ca(OH) 2 ] is used as a medicament for root canal sterilization. Root canal treatment will fail due to the imperfect removal of Ca(OH) 2 residue. The objective of this research was to analyze the comparison of the removal of Ca(OH) 2 medicaments on the root canal treatment irrigated with manual and sonic agitation technique using 2.5% NaOCI. Methods: The methods used in this study was experimental laboratory. The sample used was 30 maxillary incisors. The teeth were then divided into two groups randomly, then the root canal preparation was done by the crown down technique with irrigation using 2.5% NaOCI. The radicular part of the teeth was then split longitudinally, given a standardized groove in the one-third of the apical part, then applied with water-solved calcium hydroxide. The teeth were unified afterwards by using flowable composites, then soaked in the artificial saliva. The sample of the 1 st group was irrigated by manual agitation technique, and the 2 nd group by sonic agitation technique. The data results were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: The results of Ca(OH) 2 removal were different between manual agitation technique compared to the sonic agitation technique. Conclusion: The irrigation using 2.5% NaOCl with the sonic agitation technique were proven to be more effective in removing Ca(OH) 2 from root canals than the manual agitation technique.

Background Candida albicans is the most dominant fungus found in root canal reinfection cases. This microorganism can withstand extreme pH, low oxygen levels, lack of nutrients, and penetrate the dentinal tubules so that it can resist the intracanal medicament. Root canal cement helps prevent microorganisms and causing root canal reinfection. MTA is one of the root canals cement which is widely used and has an excellent antifungal activity, but it is less beneficial economically. Tricalcium silicate-white Portland cement (WPC) has a similar main composition as MTA, except there is no Bi2O3 content that functions as a radiopacifier. Objectives: To fabricate a mixture of tricalcium silicate-WPC with Bi2O3 through a simple solution method and investigate antifungal activity's effectiveness between tricalcium silicate-WPC added Bi2O3 and MTA to C. albicans. Materials and Methods: The 80 g of tricalcium silicate-WPC was mixed with 20 g of Bi2O3 through the simple solution method using 99.9% isopropanol as a solution. This sample solution is stirred until homogeneous, then centrifuged. The precipitate was dried until a dry powder was obtained. The powder was analyzed using X-Ray fluorescence spectrometry to identify its chemical composition and concentration. A total of 30 samples were divided into two experimental groups of tricalcium silicate-WPC added Bi2O3 and ProRoot MTA. The vials, which contain cement and C. albicans, respectively, were incubated at 37°C for 24 hours and diluted to obtain a suspension 104, 106 (0.5 in McFarland’s nephelometer) and then inoculated with sterile cotton swabs onto Saboroud Dextrose Agar Plates. The plates were incubated at 37°C for 24 hours. The measurement of colony number of C. albicans was counted by colony counter (CFU/ml). Results: The Bi2O3 was revealed in tricalcium silicate-WPC based on XRF characterization, and the antifungal test showed that both materials were effective against C. albicans. There was no statistically significant difference in the number of C. albicans colonies between tricalcium-WPC added Bi2O3 and MTA (p>0.05). Conclusion: The mixture of Bi2O3 in tricalcium silicate-WPC was successfully fabricated through a simple solution method, and both samples were effective against the C. albicans.

The change of the tooth colour could be restored with bleaching. The tooth bleaching will affects the surface roughness of the composite resins. Recently, the material basis for composite resins has developed, among others are methacrylate-based and silorane based composite resins. The objective of this study was to distinguish the surface roughness value of methacrylate-based composite resin and silorane based composite resins. This research was quasi-experimental. The sample used in this study were methacrylate and silorane based composite resins in discs form, with the size of 6 mm and the thickness of 3 mm, manufactured into 20 specimens and divided into 2 groups. The control group was immersed in the artificial saliva, and the treatment group was applied with 40% hydrogen peroxide. The result of the experiment analyzed using unpaired sample t-test showed significant differences in the average value of the surface roughness after the application of 40% hydrogen peroxide. The average value of methacrylate and silorane based composite resins were 2.744 μm and 3.417 μm, respectively. There was a difference in the surface roughness of methacrylate and silorane based composite resin compounds after the application of 40% hydrogen peroxide. The surface roughness value of the siloranebased composite resin was higher than the methacrylate-based.
