Abstract

The dental technician program of Airlangga University teaches and trains aspiring dental technicians. During three years of study, students manufacture dental prostheses such as cobalt chromium coping and acrylic dentures and perform other procedures, such as crown and bridge restoration. However, the use of dental prostheses material might cause respiratory diseases, skin problems, and neurotoxicity. Few respiratory diseases have been reported related to the occupation of dental technician, and epidemiology studies have shown high prevalence of pneumoconiosis linked with exposure duration. Lung function disturbance severity in dental laboratories is affected by some factors, such as the characteristics of workers in such a setting. This study aims to investigate the lung function representation of students of the dental technician program of Airlangga University in relation to student characteristics in the dental laboratory. This study is an observational decriptive study. Data are obtained by using a questionnaire and a literature review, and lung physiological examination is conducted using spirometry. Examination data results are presented in the form of a ratio scale and analyzed by using descriptive statistics. Conclusion: No significant difference in lung function was observed between smokers and non-smokers and between mask-wearers and non-mask-wearers.

Abstract

Background:  Ceramic is superior in aesthetic but fragile and breakable under bite pressure . Lack of understanding of material requirements for resistance in the oral cavity and minimal ceramic processing techniques is the initial cause of the failure. Hybrid ceramic dental restoration is a material that combines the good properties of ceramics and composites that have elasticity and ensures high strength and minimize the wall thickness of the restoration. Mechanical manufacture of dental restorations currently growing, CAD CAM systems are becoming popular in the field of dentistry. CAD CAM provides the advantage that the effectiveness of the time, does not require a lot of human resources, and produce a restoration with good quality. Purpose:  To explain hybrid ceramic material and techniques of making  hybrid ceramic dental restorations with CAD CAM system. Review: Hybrid ceramic is a material that combines the advantages of ceramics and composite elasticity. This material contains a hybrid structure with two networks, ceramic and polymer are linked to each other, known as double hybrid network. It added that the structure of the ceramic feldspathic network (86% wt) is reinforced by a polymer network (14% wt) are integrated as a polymer network filling cavities that exist in the network and make its structure ceramic hybrid ceramic material becomes denser. Conclusion: Hybrid ceramic having chewing load capacity and high elasticity, flexural strength  150-160 Mpa and fracture toughness 1.5 Mpa, higher than conventional ceramics. Mechanical manufacture of dental restorations using ceramic hybrid materials with CAD CAM method begins with scanning, selection of materials and tooth shade, designing, milling, followed by finishing, polishing, ends with staining and glazing.

Abstract

Background: Certain cases such as anterior cross bites require a different aesthetic removable denture technique from the conventional removable denture. Purpose: To provide an overview of a case about the technique of making aesthetic acrylic resin removable partial dentures for anterior tooth replacement in cases of anterior cross bite. Case analysis: The study examined the working model with maxillary and mandibular anterior cross bite cases. Result: The arrangement of artificial teeth was carried out as ideally as possible, so that it became harmonious. In this case, the incisal artificial teeth 11, 12, 21 were brought forward labially, so that an edge-to-edge position was formed with the opposing teeth. The clasp made was a half jackson which was placed on teeth 15 and 25, so that when the patient smiles the clasp is not visible to fulfill the aesthetic requirements. Conclusion: The technique of making aesthetic removable partial dentures in cases of anterior cross bite that has received more attention is the arrangement of the dental elements because it is different from the normal tooth arrangement. The artificial teeth were arranged in edge-to-edge bite position in order to obtain a harmonious occlusion while taking into account of the labial arch of the adjacent tooth as well as occlusion with the opposing tooth.

Abstract

Background: infectious disease is one major important health issue. Dental technician is an occupation which has a risk to get infectious disease transmitted from saliva, blood or contaminated tools if universal precaution utensils did not use properly. Infection can be transferred through dental impression from surface contact, handpiece, burs, pumice, aerosol etc. Purpose: This study aim to find out desinfection implementation in dental laboratories located in East Java as a preventive and controlling action towards cross infection. Method: Data were obtained through questionnaire, the questionnaires were designed to get the information related to infection control from dental laboratories in East Java. The survey was conducted in 36 dental laboratories listed by Association of Dental Technician in East Java. Result: As much as 90% dental laboratories did not performed desinfection procedure to the dental impression received from dentist and never follow any desinfection training. AS much as 95% Dental laboratories believe universal precaution utensils can be infected but only 50% utilize universal precaution utensils. Eventhough if such infection occurs, the owner will be fully responsible. Conclusion: Prevention and management towards cross infection control in dental laboratories located in East Java still very low. Development and supervision towards dental laboratories operational by Indonesian government  and professional association need to be improved. Education regarding infection control need to be performed through trainings and inserted infection control matters in dental technician study programme curriculum in Indonesia.
