ABSTRACTDuring orthodontic treatment, the bracket loose often occurs so that a fast, effective andeconomical cleaning method is needed. The most important thing is the character of thecleaned bracket, the quality does not change so it can be reinserted. The objective of thisresearch is to find a solvent that can remove adhesive material from base metal bracketwithout changing the metal bracket characteristics and more effective than commonlyused method i.e. sandblasting and burning. The search for a solvent system involvesvarious types of solvents and their supporting factors thermal, catalyst and surfaceagent. The adhesive release was monitored by Shear Bond Strength SBS test onreused tooth and new tooth, surface topography observation and composition withScanning Electron Microscopy SEM and Electron Dispersive X Ray Spectroscopy EDAX as well as an overview of residual adhesive with Modified Adhesive RemnantIndex ARI . The study specimens consisted of seventy metal brackets of Stainless SteelMini Dyna Lock and one hundred first Premolar teeth with Transbond XT adhesives.The result of this research is the solvent system with organic solvent N Methyl 2 Pyrrolidone, catalyst Zn Acetate, surfactant Triton X 100 and microwave. Two wayAnova Test of SBS sandblasting, burning and solvolysis values showed significantdifferences p "

"Etiologi gangguan sendi temporomandibula adalah kompleks dan multifaktorial. Selama ini diagnosa ditegakkan berdasarkan tanda klinis dan gejala. Tujuan penelitian ini adalah untuk menghasilkan suatu indeks berdasarkan etiologi dalam penetapan diagnosis, sehingga pencegahan dan perawatan yang tepat dapat dilaksanakan. Penelitian dibagi dalam dua tahap. Pertama, tahap kualitatif eksploratif melalui konsep konsensus pakar untuk menentukan variabel dan indikator yang diduga menjadi penyebab gangguan sendi temporomandibula dan akan digunakan pada kuesioner etiologi gangguan sendi temporomandibula. Tahap ke dua penelitian kuantitatif, pembuatan indeks berdasarkan etiologi gangguan sendi temporomandibula, menggunakan baku emas RDC/TMD dengan desain kasus kontrol. Dihasilkan indeks yang mudah, sederhana, dan akurat untuk memprediksi etiologi gangguan sendi temporomandibula. Indeks tersebut terdiri atas stres, kebiasaan buruk, jenis kelamin, dan free way space yang merupakan bagian dari faktor maloklusi. Komponen kebiasaan buruk dan komponen stres diukur menggunakan kuesioner yang didapat dari proses ekploratif kualitatif. Kuesioner ini adalah valid (sahih) dan reliable (andal) untuk digunakan dalam penentuan etiologi gangguan sendi temporomndibula.

The etiology of temporomandibular disorders is complex and multifactorial. Usually diagnosis was done by clinical signs and symptoms. The purpose of this research is to produce an index based on etiology so early prevention and prompt treatment can be done. This study was divided in two stages. Firstly the qualitative explorative concept. It was done to get a consensus between the experts to define variables and indicators that were suspected as the causes of temporomandibular disorders. The variables and indicators will be used in the questionnaire based on the etiology of Temporomandibular disorders. Then, followed by a quantitative study with case-control design using the RDC/TMD as a gold standard, producing an easy, simple, and accurate index to predict the etiology of temporomandibular disorders. Included in this index are stress, bad habits, gender, and free way space which is a part of a malocclusion. Bad habit and stress could be measured by using a questionnaire which was obtained from a qualitative explorative study. This questionnaire is valid and reliable in the determination of the etiology of temporomandibular disorders."

"ndonesia termasuk negara dengan struktur penduduk menuju tua. Prevalensi periodontitis dan hendaya kognitif meningkat seiiring dengan meningkatnya populasi lanjut usia. Penelitian ini bertujuan untuk mendapatkan implikasi periodontitis terhadap hendaya kognitif melalui status periodontal dan komposisi mikrobiota subgingiva. Desain penelitian adalah kasus kontrol. Status kognitif diperiksa menggunakan instrumen Hopkins Verbal Learning Test dan Mini-Mental State Examination yang telah divalidasi. Pemeriksaan faktor risiko hendaya kognitif meliputi status periodontal (indeks plak, indeks kebersihan mulut, indeks perdarahan papila, jumlah gigi, unit gigi fungsional, dan tingkat keparahan periodontitis), faktor sosiodemografi, serta sistemik dan lingkungan. Komposisi mikrobiota subgingiva diperiksa dari cairan krevikular gingiva. Hasil penelitian menunjukkan bahwa indeks plak, indeks perdarahan papila, jumlah gigi, usia, lama pendidikan, dan status hipertensi merupakan faktor-faktor yang paling berperan terhadap status kognitif. Terdapat hubungan bermakna (p<0,05) antara semua variabel status periodontal dengan status kognitif. Terdapat keragaman mikrobiota subgingiva antara subjek periodontitis lansia yang hendaya kognitif dengan kognitif normal. Abundance Porphyromonas gingivalis dan Treponema denticola lebih tinggi pada subjek lansia hendaya kognitif. Berdasarkan hal ini, dapat disimpulkan bahwa periodontitis merupakan faktor risiko hendaya kognitif.

Indonesia is a country with an aging population. The prevalence of periodontitis and cognitive impairment increases along with the increase in the elderly population. This study aims to obtain the implications of periodontitis on cognitive impairment through periodontal status and subgingival microbiota composition. The design of this study was case-control. Cognitive status was assessed using the Hopkins Verbal Learning Test and Mini-Mental State Examination instruments. Examination of risk factors for cognitive impairment includes periodontal status (plaque index, oral hygiene index, papilla bleeding index, number of teeth, functional tooth units, and severity of periodontitis), sociodemographic factors, also systemic and environmental. The composition of the subgingival microbiota was examined from the gingival crevicular fluid. The results showed that plaque index, papilla bleeding index, number of teeth, age, length of education, and hypertension status were the factors that most contributed to cognitive status. There was a significant correlation (p<0.05) between all variables of periodontal status and cognitive status. There was a diversity of subgingival microbiota between cognitively impaired with cognitively normal in elderly subjects. The abundance of Porphyromonas gingivalis and Treponema denticola was higher in cognitively impaired elderly subjects. It can be concluded that periodontitis is a risk factor for cognitive impairment."
