Abstract-Dental laboratory technicians may be exposed to metal alloys that are used in the production of crowns, bridges and removable partial dentures. The aim of this study was to assess whether dental technicians are occupationally exposed to Cobalt, Nickel and Chromium by analyzing the concentration of Cobalt, Nickel and Chromium in the blood level and to investigate the effects of occupational environmental controls associated with dental prostheses production in dental laboratories in East Java Indonesia. Result found shows that the concentration of Cobalt, Nickel and Chromium in the blood level of dental technicians are higher than the certified reference material level recommended. The concentration of Cobalt, Nickel and Chromium in the dental technicians' blood level are 27 µg/L, 37 µg/L and 117 µg/L respectively. Although 50% of dental laboratories surveyed had ventilator and air dust respirator, almost all of the technicians did not do personal occupational environmental controls correctly.

Background: This is an initial study of the biofilm of Streptococcus mutans (S.mutans) and Aggregatibacter actinomycetemcomitans (A.a). S. mutans and A.a are bacteria that cause infection diseases in the oral cavity. These bacteria have the ability to form biofilms. The study of bacterial biofilm proteins was used as an alternative to early prevention for oral infections. It would be used for the purpose of creating a marker for Infection Detection Kit in the oral cavity. Objective: To easily detect caries or Periodontitis with the biofilms of S. mutans and A.a at the early stage. The forming of biofilm proteins from S.mutans and A.a induced with 5% glucose, 5% lactose, 5% soy protein, and 5% iron will be use as a marker for early detection to Dental caries and Periodontitis. Methods: SDS-PAGE electrophoresis technique was used in the study to measure the molecular weight of S. mutans and A.a biofilms induced with 5% glucose, 5% lactose, 5% soy protein, and 5% iron. Results: Biofilm bands of S. mutans and A.a were formed with the various numbers depending on the induction used. These results are early chararterization of biofilm that will beused as a marker for early detection of infectious diseases in oral cavity (Dental Caries and Periodontitis). Conclusions: S. mutans bacteria induced with 5% glucose had one band of biofilm protein, with 5% lactose had four bands of biofilm proteins, and with soy protein had seven bands of biofilm protein, but with 5% iron did not produce any protein bands and neither did A.a.

BackgroundMaintaining proper oral hygiene has an influence on oral health. Religious obedience may influence individual behavior. According to Islamic religious guidance, as recommended by an Islamic role model, it is obligated to maintain oral health and the recommended tool to use is miswak.PurposeTo describe miswak users’ behavior based on the theory of planned behavior.Subjects and methodsThe population of this study was the students of As-Salafi Al-Fitrah Islamic Boarding School who used miswak regularly and were healthy physically and mentally. One hundred and nine samples were chosen randomly and asked to complete a semi-open and a closed-ended questionnaire.ResultsPerceived behavioral control had the most dominant influence toward improving intention with β=0.211 and p<0.05. In contrast, attitude and subjective norms had less influence toward improving intention with β=0.190 and p>0.05, and β=0.164 and p<0.0001, respectively. Meanwhile, perceived behavioral control showed direct correlation toward action in model parameter with β=0.445 and p<0.0001.ConclusionPerceived behavioral control is the most dominant predisposing factor in increasing intention and attitude of miswak use.
