Abstract

Dental treatment can be said successful if the denture can restore masticatory and esthetic function and keep oral tissue in healthy condition. The success of full denture treatment depends on some factors, which are procedural techniques of full denture processin, which include clinical and laboratory phases. Besides technical aspects, there are some nontechnical aspects which include emotional characteristic of the patient, relation or communication between patient and dentist, patients motivation and information about full denture. Thses aspects are often forgotten by dentists, because they emphasize more on technical aspects. This article describe the aspects of nontechnical procedures in making full denture and its connection with the success of full denture treatment. The conclusion of this paper is that it is necessary to communicate clearly with a patient who needs full enture treatment, orally with simple and understandable language, along with demonstrations and written information about diagnosis, prognosis and the treatment plan of the procedure which will be conducted according to the patients character.

Abstract

Background: Tissue engineering based approaches have received much attention. Incorporation of chitosan and carbonate apatite (CA) improve its capability. Human mesenchymal stem cells (hMSCs) is viable for xenogenic transplantation. The purpose of this study was to fabricate and evaluate the osteogenic potential differentiation of human amnion mesenchymal stem cell with carbonate apatite– chitosan scaffolds (CA-ChSs) for tissue engineering. Method: Human amniotic membrane was procured from using cesarean section. Soncini’s protocol was employed for the isolation procedure. The cells cultured on collagen-coated dishes using Dulbeccos minimal essential medium (DMEM)/F12 (1:1). A chitosan powder of medium molecular weight deacetylated chitin, poly(D(glucosamine) was used and mixed with CA. Immunocytochemistry and flowcytometry used for phenotypic characterization of hAMSC. Result: Amniotic membrane obtained using cesarean section under aseptic condition did not exhibit any growth of cell cultures which were not contaminated. Immunocytochemistry testing revealed that the target cells expressed strong mesenchymal stem cell marker CD 105. Characterization at passage 10 showed that CD44 was the most significant and abundant surface receptors. The number of viable cells in chitosan-carbonate apatite was 66.59%. Scanning electron microscope (SEM) observation revealed that CA-ChSs had three-dimensional structure with many pores and hAMSc could attached and proliferation among the porosity of the scaffold. The formation of calcium in the cell as an indicator of osteoblast cells was detected using Alizarin Red solution. Conclusion: hAMSc harvested from human amniotic membrane seeding in CA- ChSs had the capability for in vitro osteogenesis makes them be the one of the potential options for bone tissue engineering.

Abstract

Denture stomatitis is an inflammation of oral cavity due to removable denture wearing. Prevention of denture stomatitis can be effectively done by using mouth rinsing. Currently, Indonesian government is actively promoting traditional herbal medicine as an alternative medicine such as Psidium guajava Linn leaf which has an anti bacterial and anti fungal ability. The purpose of this study was to know the effective concentration and soaking duration to reduce Candida albicans without lowering transversal strength of acrylic resin. This experimental laboratory study was using heat cured acrylic resin plate without surface polishing. The concentration of Psidium guajava Linn leaf extract used in this study were 32%, 34%, 36%, and 38% respectively with 15 minutes, 30 minutes, 1 hour and 8 hours soaking duration. The transversal strength was measured in the same concentration with 2 days, 10 days and 60 days soaking duration. Sterile aquadest was used as control. Two direction ANOVA and LSD test were used in data analysis. The result showed significant difference in the number of Candida albicans colony among concentrations and soaking durations. Significant difference was also found in transversal strength among concentrations and soaking durations. It is concluded that the extract of Psidium guajava Linn leaf in 38% concentration with 8 hours soaking duration will lower the Candida albicans colony, whereas 38% concentration with 60 days soaking duration will lower the transversal strength but it is still above the standard value.

Abstract

Background: Acrylic resins, especially poly methyl methacrylate (PMMA) was introduced in 1937. Acrylic resin has favorable properties, among others, aesthetic, color and texture similar to that of the gingival aesthetic in the mouth, relatively low water absorption and dimensional changes. However, some studies suggest that the duration of storage of acrylic resin will affect the changes in the glass transition temperature and the mass of acrylic resin. Purpose: The objective of this research was to study the effect of humidity and storage time led to changes in the glass transition temperature and the mass of the acrylic resin. Methods: The research method is experimental laboratory. Acrylic resin specimens are kept in conditions of humidity of 90%, 70%, 40% and 30% for 24 hours, one week, one month and two months. In this study used three methods of curing, namely conventional JIs, 24-hour curing at 70 °C and using the microwave. Results: Low humidity causes changes in the glass transition temperature and the mass of acrylic resin. Longer storage of acrylic resins in low humidity, can affect change greater than the glass transition temperature and the mass of acrylic resin. Conclusion: It can be concluded that the humidity and longer storage of acrylic resins can affect the glass transition temperature and a change in mass.Latar belakang: Resin akrilik terutama poli metil metakrilat (PMMA) telah diperkenalkan pada tahun 1937.
