Abstract

Pendahuluan: Kelemahan dari komposit konvensional adalah terjadinya shrinkage dan stress polimerisasi. Penggunaan serat sebagai bahan pengisi pada resin komposit dapat menurunkan kontraksi polimerisasi. Berdasarkan penelitian sebelumnya serat sabut kelapa memiliki daya antibakteri yang cukup baik karena mengandung golongan senyawa metabolit sekunder yaitu tanin, flavonoid, dan polifenol. Selain itu juga memiliki beberapa senyawa, antara lain asam elagat, asam galat, epikatekin, dan katekin yang juga diperkirakan memiliki aktivitas sebagai anti bakteri. Serat sabut kelapa tidak dapat digunakan secara langsung dalam bentuk aslinya sehingga dibutuhkan modifikasi untuk membersihkan serat. Tujuan penelitian menganalisis perbandingan daya antibakteri serat selulosa sabut kelapa (Cocos nucifera L.) pada konsentrasi berbeda terhadap S. mutans. Metode: Jenis penelitian true experimental dengan desain penelitian posttest only control design. Ekstraksi serat selulosa dari sabut kelapa melalui proses bleaching kemudian sintesis selulosa menggunakan NaOH dan urea selanjutnya di nukleasi dengan etanol sebagai anti solvent organik dan dikeringkan dengan proses sublimasi. Pengujian aktivitas antibakteri menggunakan metode sumur difusi dengan dua konsentrasi uji yaitu kelompok 1 menggunakan anti solvent etanol 70% dan, pada kelompok 2 menggunakan etanol 96%. Kontrol negatif menggunakan aquadest steril. Selanjutnya diamati dan diukur diameter zona hambat dengan jangka sorong. Data yang diperoleh diuji statistik menggunakan independent t-test. Hasil: Daya antibakteri kelompok sampel yang diberi perlakuan etanol 96% lebih tinggi dibandingkan dengan kelompok sampel etanol 70%.  Hasil uji independent t-test menunjukkan bahwa nilai p yang signifikan p=0,000<0,05, Simpulan: Serat sabut kelapa yang diberi etanol dengan konsentrasi 96% terbukti memiliki daya antibakteri yang lebih tinggi daripada yang diberi etanol dengan konsentrasi 70%.Kata kunci: daya antibakteri; serat sabut kelapa; Streptococcus mutans ABSTRACTIntroduction: The weakness of conventional composites is the occurrence of shrinkage and polymerisation stress. The use of fiber as a filler in composite resins can reduce polymerisation contraction. Based on previous research, coconut fiber has good antibacterial properties because it contains a class of secondary metabolites, namely tannins, flavonoids, and polyphenols. In addition, it also has several compounds, including ellagic acid, gallic acid, epicatechins and catechins which are also thought to have antibacterial activity. However, coconut fiber cannot be used directly in its original form so modifications are needed to clean the fiber. This study aimed to compare the antibacterial power of coconut cellulose (Cocos nucifera L.) fibers at different concentrations against S. mutans. Methods: This type of research is true experimental with posttest only control design. Extraction of cellulose fiber from coconut fiber through a bleaching process and then synthesis of cellulose using NaOH and urea then nucleated with ethanol as an organic anti-solvent and dried by sublimation process. The antibacterial activity was tested using the diffusion well method with two test concentrations, namely group 1 using 70% ethanol anti-solvent and, in group 2 using 96% ethanol. Negative control using sterile distilled water. Then observed and measured the diameter of the inhibition zone with a caliper. The data obtained were statistically tested using independent t-test. Results: The antibacterial power of the sample group that was treated with ethanol was 96% higher than that of the 70% ethanol sample group. The results of the independent t-test obtained the p-value of p=0.000; p<0.05. Conclusion: Coconut fiber which was given ethanol with a concentration of 96%, proved to have higher antibacterial power than that given ethanol with a concentration of 70%.Keywords: antibacterial activity; coconut fiber; Streptococcus mutans

Abstract

Background : A common objective of anterior restorative dentistry is to establish anterior guidance between the maxillary and mandibular anterior teeth to disclude the posterior teeth during protrusive mandibular movement. Fracture anterior teeth leads to psychological trauma, along with functional and esthetic debilitations. Healthy anterior teeth play an important role of protecting the posterior teeth during excursive mandibular movement. The contour and shape of the labial surface are important for esthetic purpose; the palatal surface morphology is critical for harmonious function. Premature contact in palatal surface restoration is considered as contributing factor to temporomandibular disorder (TMD) symptoms. Purpose : Improve aesthetics and function of the patient's anterior teeth. Case : Male, 17 years old with poor aesthetic because of fracture anterior teeth 4 years ago. Case Management : Root canal treatment, treatment of root resorption, fiber post, custom post, indirect veener, zirconia crown and enameloplasty. Result : Better aesthetic and get the optimum function of his teeth.

Abstract

Dental and oral health in Indonesia is still a health problem that needs attention. The most concerning thing is that as many as 93% of school-age children experience dental and mouth problems. This can be caused by a lack of knowledge and awareness of dental hygiene. One of the efforts made to increase knowledge and awareness of dental hygiene is by holding an educational activity called the "School Health Program". This activity was carried out in several schools, one of which was TK ITS. This activity began with the Training of Trainer Program given by dentists to teacher cadres and parents of students/students/students about the benefits of good oral hygiene and how to brush your teeth twice a day with fluoride toothpaste. Dentists provide educational materials using power point media and educational videos through the zoom application. There were 5 cadres consisting of 2 teachers and 3 guardians of students who attended this activity. After that, the teacher cadres and parents of the students/students disseminate information to other parents of students/students so that they can become mentors to their children to apply good and correct behavior of brushing their teeth twice a day for 21 days with the method recorded on the given calendar. The hope is that after this program ends, students at ITS Kindergarten have the behavior of maintaining oral hygiene by brushing their teeth twice a day with fluoride toothpaste.
