Expert Lecture and Live Demo: The Latest Endodontic Treatment and Restoration with Dental Fiber Posts

Endodontic treatment of anterior trauma and caries followed by post and crown restoration is not included in the minimum standard of oral care in primary health facilities. Endodontic treatment, which requires a relatively long time and the number of visits compared to mere tooth extraction, often makes it impossible to carry out in a health facility with many patients per day. This community service was aimed to provide technical understanding and knowledge of endodontic treatment procedures for anterior teeth that are simple, up-to-date, with a minimum number of visits, and provide an understanding of the selection of dental fibre post materials that meet reasonable material requirements at a more affordable price. Methods for implementing the activities consisted of: (1) Formulation and preparation; (2) Pre-test; (3) Expert lecture; (4) Live demo; and (5) Post-test. This community service increased the knowledge and ability in endodontic treatments for anterior teeth and their restoration with dental fibre posts from the prospective dentists and dentists who were participants in this community service. This activity can also lead to the making of the latest manual and standards for endodontic treatment for anterior teeth and their restoration with dental fibre posts

Cara praktis reparasi intraoral fraktur porselen pada restorasi mahkota porselen

Today the dental porcelain is used as one option for the manufacture of dental restorations with the development of esthetic dentistry. Beside the advantages there are also disadvantages of porcelain is its britlle so easily fracture. Factors such as impact, fatigue, occlusal pressure, and the mismatch between the physical properties of metals can lead to fracture of porcelain. Fractures often occur in the maxilla (75%) and especially on the labial surface (60%). Porcelain fracture in the anterior region will interfere with the appearance of the patient. Replacement of defective restorations are not necessarily the most practical solution because it takes a long time and cost.One alternative way to handle that is to repair in the mouth. Intraoral repair to do is to use a composite resin and an assortment of treatments on porcelain and metal surfaces such as coarsening with diamond drills, sandblasting and acid hidrofluoride applications.Next,applied primer and the selected composite materials which can be universal composites. Fracture of the porcelain restoration porcelain crowns can be repaired in the mouth in a simple manner. Repair materials are used together with direct composite materials differ only in the etching material

Perbandingan porselen kedokteran gigi swa-sintesis berbahan baku pasir felspar Pangaribuan dan Sukabumi

Comparison self-synthesized dental porcelain between feldspar from Pangaribuan and Sukabumi. Dental porcelain material as one of the esthetic indirect restorations in Indonesia is mostly imported. In fact, Indonesia is really rich of natural raw materials, including feldspar, silica, and kaolinite. The aim of this study is to synthesize the dental porcelain made from Indonesia’s two different originates, which are Pangaribuan and Sukabumi. This study was prepared by fritting and sintering the mixture of 65% wt feldspar (from Sukabumi and Pangaribuan), 25% wt silica, 5% wt kaolinite, and 5% wt potassium salt. The porcelains obtained were evaluated using X-Ray Diffraction (XRD). The results revealed that quartz and leucite were found in the composition of Pangaribuan sand that successfully showed more translucencies compared to Sukabumi sand which only imparted quartz on its component. This study shows that dental porcelain from Pangaribuan sand is successfully self-synthesized, on the other hand Sukabumi sand has not been successfully synthesized. These findings develop on a good prospect of esthetic dental porcelain made from Indonesian natural sand. ABSTRAKBahan porselen kedokteran gigi sebagai salah satu restorasi indirek estetik di Indonesia kebanyakan didatangkan dari luar negeri.
