Pengaruh Lama Penyinaran dan Ketebalan Resin Komposit Bulk Fill Terhadap Kebocoran Mikro

Restorasi gigi bertujuan  mengembalikan fungsi mastikasi, fonetik, estetik, dan perlindungan terhadap jaringan pendukung gigi. Resin komposit merupakan bahan restoratif yang digunakan di kedokteran gigi karena  mempunyai estetik dan kekuatan yang baik. Salah satu kekurangan dari resin komposit yaitu polymerization shrinkage. Pengkerutan akibat polimerisasi dapat menimbulkan kebocoran mikro, sehingga menyebabkan kegagalan restorasi berupa karies sekunder, diskolorasi dan infeksi pulpa. Polimerisasi resin komposit dikatakan baik apabila derajat konversi berupa ikatan atom karbon ganda menjadi ikatan tunggal pada monomer berjalan dengan tepat. Hal tersebut dipengaruhi beberapa faktor seperti translusensi bahan, lama penyinaran, ketebalan resin komposit, dan tipe filler. Beberapa cara untuk mengurangi kebocoran mikro diantaranya adalah teknik penumpatan secara incremental. Kekurangan teknik ini yaitu memperlambat proses perawatan dan meningkatkan risiko kontaminasi setiap lapisannya. Saat ini telah dikembangkan resin komposit bulk fill yang mampu diaplikasikan ke dalam kavitas secara langsung (bulk) dengan ketebalan 4-5 mm, dapat mengalami polimerisasi dengan baik. Penulisan ini bertujuan untuk mengetahui pengaruh lama penyinaran dan ketebalan resin komposit bulk fill terhadap kebocoran mikro. Semakin lama penyinaran maka menyebabkan peningkatan ikatan karbon yang memperkecil jarak antar monomer. Peningkatan ketebalan aplikasi bahan meningkatkan nilai c-factor yang menyebabkan terjadinya pengkerutan sehingga menyebabkan kebocoran mikro. Beberapa studi menggunakan metode dye penetration dengan larutan marker yang berbeda untuk mengukur kebocoran mikro. Evaluasi dilakukan menggunakan Scanning Electron Microscopy (SEM), mikroskop cahaya, dan micro-CT. Kesimpulan literature review ini menunjukkan bahwa terdapat pengaruh lama penyinaran dan ketebalan resin komposit bulk fill terhadap kebocoran mikro

The evaluation of taste sensitivity between conventional and electric smokers

Background: Taste has an important role in human life because of the sense of taste, humans have an ability to taste various flavors of food. Decreased taste sensitivity can affect the quality of life and cause a person to consume excessive taste substances. One of the factors associated with decreased taste sensitivity is smoking. Currently, a new type of cigarette (electric cigarette or e-cigarette) is being developed which is favorable to young people because it has a different content, shape, and taste compared to conventional cigarettes. E-cigarettes are considered safer because aerosol does not contain the tobacco content of conventional cigarettes and is an alternative to smoking cessation programs. The purpose of this study is to evaluate the difference in taste sensitivity between conventional smokers and e-smokers. Method: This research is an analytical observational study using a cross-sectional design. The research subjects were conventional and electric smokers who were students of Universitas Muhammadiyah Yogyakarta. The research subjects were obtained by purposive sampling, a total of 32 people who had met the inclusion criteria. Data analysis used frequency tables for univariate data and an-independent sample T-test for bivariate data. Result: The results of the bivariate analysis showed a significant value between conventional and electric smokers with p = 0.036 (< 0.05) for sweet, salty, and sour tastes, while for bitter tastes p = 0.031 (< 0.05). Conclusion: Taste sensitivity in conventional smokers is less sensitive than in electric smokers. Sensitivity to bitter tastes in both treatment groups is less sensitive than sweet, salty, and sour tastes

Estimation of tertiary dentin thickness on pulp capping treatment with digital image processing technology

Dentists usually observe the tertiary dentin formation after pulp capping treatment by comparing periapical radiograph before and after treatment visually. However many dentists find difficulties to observe tertiary dentin and also they can’t measure exactly the thickness of the tertiary dentin. The aims of this study is to assist the dentists to measure the area of tertiary dentin and calculate the dentin formation using b-spline image processing. The dental radiograph of 38 patients of pulp capping in the Dental Hospital Universitas Muhammadiyah Yogyakarta, Indonesia. Each of patient visited dental hospital 3 times. First, the patient got an application of pulp capping material. Second, after one-week treatment and temporary restoration and the third, after more than one month with the composite as the final restoration. Every visited the patient take a radiograph. Dentist placed the dot from the patient's radiograph. The dots were combined and processed with digital image processing. The b-spline method changed the dot to one area. After the calculation, the dentist can see whether there was dentin formation which means it is one of the treatment success indicators. Dentist has the better view to measure the dentin formation by providing area value of its tertiary dentin thickness calculation. We compare the result to the program calculation using the b-spline method and visual observation from the dentist. This study indicated the thickness of tertiary dentin can be measured by this program with an accuracy of 94.2%. Therefore, dentist can make tertiary dentin thickness prediction from patient’s radiograph

Effect of Probiotic and Propolis in the EPS of Root Canal Bacteria Biofilm

Objective: This study aimed to evaluate the effects of Apis trigona ethanolic propolis and probiotic bacteria Lactobacillus acidophilus on the nucleic acid concentration in the extracellular polymeric substances (EPS) derived from biofilm of root canal bacteria. Materials and Methods: Clinical bacteria of the root canal were cultured with ethanolic extract of propolis (EEP; 10 or 0.1%) and L. acidophilus. After the formation of biofilm was observed in the monolayer bacterial culture under several conditions, the enzymatic treatment and nucleic acid quantification were sequentially performed. Statistical Analysis: Independent t-test and Mann–Whitney were performed following data normality to analyze the significant differences of the treatment effect on the nucleic acid concentration in EPS from the isolated biofilm. Results: The results showed that the nucleic acid concentration in EPS biofilm were not increased by coculture with L. acidophilus as probiotics. However, the treatment with 10% EEP could significantly increase nucleic acid concentration. Conclusion: This study suggested that the biosurfactants from probiotic bacteria L. acidophilus might be a promising candidate for endodontic treatment, arguably better than EEP in inhibiting biofilm maturation and complexity
