Abstract

Background: One of the main cancer treatments is chemotherapy – a systemic treatment of cancer.Chemotherapy can kill cancer cells quickly, however it can also kill the healthy cells in human body. The morechemotherapy is done, the more cancer cells are damaged, and so are the healthy cells. One of the healthy cellsthat will be affected is oral cavity cells which can cause side effects, like xerostomia. Chemotherapy drugs aretoxic and it can lead to destructive effects on salivary glands. Xerostomia can cause the reduced function ofsaliva as self-cleansing, thus it can be one factor to facilitate the forming of plaque. Purpose: The objective ofthis research is to identify the difference of plaque index score on cancer patients who are undergoingchemotherapy based on the frequency in RSUD Ulin Banjarmasin. Method: This research uses expost factomethod with cross sectional approach. The samples of this research are 80 patients with cancer who areundergoing chemotherapy. Result: The data is tested by using nonparametric Kruskal Wallis test with p<0.05(p=0.001) shows that there is a meaningful difference of plaque index score within each group. Conclusion:According to the research that has been conducted, it can be concluded that there is a meaningful difference ofplaque index score in patients with cancer who are undergoing chemotherapy based on their frequency.

Abstract

ABSTRAKLatar Belakang: Pegas jari merupakan pegas yang dapat menggerakkan gigi anterior ke arah mesial atau ke arah distal. Gaya yang diberikan dalam perawatan ortodonti tidak boleh melebihi tekanan darah kapiler yaitu 20-25 gr/cm2, jika lebih dari itu maka dapat terjadi nekrosis pada jaringan sekitar. Untuk menggerakan gigi yang berakar tunggal diperlukan kekuatan antara 25-40 gram, kekuatan dibawah dari 25 gram tidak memungkinkan terjadinya pergerakan gigi dalam waktu yang optimal, sedangkan kekuatan yang besar diatas 40 gram akan dapat mengakibatkan kerusakan jaringan periodontal dan akan menimbulkan rasa sakit yang berlebihan. Tujuan: untuk mengetahui perbandingan daya lenting pegas jari antara diameter kawat 0,5 mm dengan 0,6 mm pada alat ortodonti lepasan. Metode: Jenis penelitian ini merupakan pre- experimental dengan metode one- shot case study menggunakan simple random sampling, terdiri dari 2 kelompok perlakuan dengan diameter kawat 0,5 mm dan dengan diamter kawat 0,6 mm, masing-masing sampel diaktivasi sebanyak 3 mm kemudian dilakukan pengukuran daya lenting yang dihasilkan dengan menggunkan gauge force meter. Hasil: Rata-rata daya lenting yang dihasilkan dari sampel pegas jari diameter kawat 0,5 mm (70gr/mm²), dan rata-rata daya lenting yang dihasilkan dari sampel pegas jari diameter kawat 0,6 mm (129,6 gr/mm²). Hasil uji independen T-test menunjukan bahwa terdapat perbedaan yang bermakna antara pegas jari dengan diameter kawat 0,5 mm dan 0,6 mm. Kesimpulan: Pegas jari dengan diameter kawat 0,5 mm lebih efektif digunakan karna daya yang dihasilkan lebih kecil dibandingkan dengan diameter kawat 0,6 mm.

Abstract

ABSTRACTBackground: Composite is broadly used by dental practitioners as restoration material to treat caries. Nanohybrid composite is a type of composite composed of nano-sized filler combined with larger filler. Polymerization shrinkage commonly occurs in every restoration using composite, resulting in a gap between cavity margin and teeth structure, which eventually leads to microleakage. Purpose: The purpose of this study was to assess and measure the rate of nanohybrid composite microleakage as a result of temperature change from 5ºC to 60ºC. Methods: This study was true experimental with post test-only with control design. Specimens used were 20 maxillary premolars, divided into 2 groups: 5ºC to 60ºC temperature change treatment group and control group (without temperature change, sitting idly at 37ºC).  Results: Mean scoring of treatment group was 3 and control group was 1,9. Conclusion: It can be concluded that independent samples T-test presented significant difference between treatment group and control group.  ABSTRAKLatar Belakang: Komposit merupakan suatu bahan restorasi yang biasa digunakan oleh dokter gigi untuk menumpat gigi yang karies. Komposit nanohybrid merupakan salah satu jenis komposit yang memiliki komposisi filler berukuran nano dan digabung dengan filler yang berukuran besar. Pengerutan polimerisasi merupakan hal yang selalu terjadi pada setiap penumpatan dengan bahan komposit. Akibat dari pengerutan adalah terbentuknya celah antara tepi kavitas dan struktur gigi, hal tersebut akan menyebabkan kebocoran mikro. Tujuan: Tujuan dari penelitian ini adalah untuk mengetahui adanya kebocoran mikro pada komposit nanohybrid akibat perubahan suhu 5ºC ke 60ºC serta mengukur besar kebocoran mikro yang terjadi. Metode: Jenis penelitian ini merupakan eksperimental murni dengan rancangan post test-only with control design. Penelitian ini menggunakan gigi premolar rahang atas sebanyak 20 buah yang dibagi menjadi 2 kelompok, yaitu kelompok perlakuan perubahan suhu 5ºC ke 60ºC, dan kontrol yang tidak dilakukan perubahan suhu atau didiamkan pada suhu 37ºC. Hasil: Rata-rata skor untuk kelompok perlakuan adalah 3 dan kelompok kontrol adalah 1,9. Kesimpulan: Dapat disimpulkan bahwa hasil uji T-test tidak berpasangan  menunjukkan perbedaan yang bermakna antara kelompok perlakuan dan kelompok kontrol.
