Modelling wax is a pattern wax for complete denture fabrication. It consists of various waxes and other components. Thecomposition influenced the physical properties of modelling wax. The objective of this study was to examine the effect ofparaffn to beeswax ratio on the linear thermal expansion (LTE) of modelling wax. The modelling waxes consist of paraffin (Pertamina, Kalimantan), beeswax (SEA, Yogyakarta), carnauba wax (PT Bratachem, Indonesia), and dammar(Kalimantan). Five compositions of waxes were made with different paraffin to beeswax ratio (paraffin: beeswax: carnauba wax: dammar in % weight): K1 = 70:20:4:6, K2 = 72.5:17,5:4:6, K3 = 75:15:4:6, K4 = 77.5:12.5:4:6, and K5 =80:10:4:6. Six specimens (305 x 22.2 x 14.3 mm) were made of each composition. The specimens were immersed inbathing water at 25Â°C and 40Â°C for 20 minutes, and the specimen length was measured by travelling microscope aftereach immersion. The percentage of the LTE was measured. Data were analyzed by one-way Anova and LSD0.05. Theresults showed that the LTE of modelling waxes was between 0.27 + 0.02 % (70:20 ratio) and 0.73 + 0.06 % (80:10ratio). The Paraffin to beeswax ratio influenced the LTE of modelling waxes and showed the significant differencesbetween all compositions (p<0.5). As conclusion, the paraffin to beeswax ratio influenced the linear thermal expansion ofmodelling wax.

Macrophage plays an essential role in innate immune system by phagocytosing bacteria. However, the phagocytosisprocess may activate macrophage to release inflammatory mediators which may cause tissue destructions in strongreaction. Kaempheria galanga L. is one of medical plants which is believed having potency as an immunomodulatoragent. The aim of this study was to examine macrophage cells phagocytic activity of Actinobacillus actinomycetemcomitans after stimulated with Kaempheria galanga`s essential oil in vitro. Mouse peritoneal macrophages wereincubated with 5%, 10%, and 20% of Kaempheria galanga`s essential oil at 37oC in an atmosphere containing 5% CO2.After 15 minutes, A. actinomycetemcomitans was added to the suspension and incubated for 30 minutes. At the end of theincubation period, the cells were assayed for the phagocytic activity. The result of this study showed that Kaempheriagalanga`s essential oil significantly reduced the percentage of mouse macrophage cells phagocytosing A. actinomycetemcomitans and the number of phagocytosed A. actinomycetemcomitans per 1 macrophage cell in vitro (p<0,05). Inconclusion, Kaempheria galanga`s essential oil may reduce mouse macrophage cells phagocytic activity of A.actinomycetemcomitans.

Fabrication of prostheses must be planned and designed to fit harmoniously with the complexity of the neuromuscularsystem of the patient, the temporomandibular joints and supporting structures of the teeth. Any occlusal interference fromthe prostheses would invade the systems and caused various problems to the patient. The aim of this study was to evaluatethe occlusion of 3-unit conventional bridges prior to cementation. All bridges that scheduled for cementation was noted.Before the occlusal examination was performed, the retainers were examined to ensure good marginal fit and haveadequate interproximal contact with adjacent teeth. Occlusal examination was performed using articulating foil with thethickness of 8Âµm, Millerâ€™s forceps and thickness gauge. From 33 bridges identified, 93.9% were qualified for occlusalexamination. Most of the retainers and pontics showed multiple high spots. From 62 retainers and 31 pontics, 213occlusal contacts were obtained, with 25.8% on cuspal inclinations, 24.4% presented with high spots on marginal ridgesand 11.7% on cuspal tips. The thickness of the high spots ranges from 0.5-3.6mm. High occlusion could be resulted fromvarious factors such as inadequate tooth preparation and lack on the usage of semiadjustable articulator. Occlusalexamination has to be performed prior to bridge cementation to ensure comfort during functioning and health of the hardand soft tissues.

Several non invasive methods have the results showed that been applied to quantify facial soft tissue morphology. Digitalphotography is one of the methods that has been used in the assessment of facial profile in different population. This studyaims to determine nasal soft tissue differences among Malays in Peninsular Malaysia by applying geometricmorphometric method with digital photograph. A cross sectional study was carried out on 20 participants from Bugis andJava females with aged range from 20-40 years. The photographs were captured using digital SLR camera (Nikon D80)and analyzed using finite element analysis in MorphoStudioTM software. Seven soft tissue landmarks were digitized oneach frontal photograph and six on the lateral one. The study error for both samples was within acceptable limits as therewere no statistical differences (p>0.05) in duplicated digitization. The results showed that the comparison of size revealedthat Bugis females were smaller in upper and lower nasal region about 17- 33%. Bugis females shape showed differencesin upper and lower nasal area by 20%. In lateral profile there was a decreased size in lower nasal area in Bugis females by17- 33% and the difference in shape by 20%. The nasal region was significantly smaller in size and more different inshape for Bugis females than Javanese females. Computer aided photogrammetric analysis has the ability to depict andquantify local shape and size changes of nasal soft tissue differences between Java Malay and Bugis female groups.

Residual ridge resorption and remodeling directly affect the function of removable prostheses which relies greatly onthe quantity and architecture of jaw bones. The purpose of this study was to assess the remaining bone height level inrelation to some pathophysiologic factors that may affect on the resorption process. The factors involved in this studywere Diabetes mellitus, periodontitis, menopause, and edentulousness time (more than 10 years). Maxillary andmandibular bone height on 115 dental panoramic radiographs belonged to full edentulous patients were measured andcompared to 35 controls using MB Ruler software. The soft images were collected using the radiographic machines inthe faculty of dentistry. The measurements included maxillary middle anterior and lateral bone heights, middlemandibular dimension, right and left mental bone heights. The results showed that women with completely edentulousarches showed relatively higher rate of bone resorption than men, and control group. Indian patients also demonstratedhigher bone resorption rate, particularly on the mandible, followed by Chinese and Malay. In regard to different healthconditions, edentulousness time for more than 10 years showed the minimal bone height reduction that affected mainlythe mandible sides compared to other conditions and the control group. On the sides of maxilla, periodontitis exhibitedhigher effect on the residual ridge resorption rather than other studied conditions. However, on the middle of maxilla,menopause was associated with maximum bone resorption compared to the others. As conclusions, residual ridgeresorption in completely edentulous patients may be influenced by gender, race and patientâ€™s health conditions.

A basic material of polymethyl methacrylate (PMMA) acrylic resins is methyl methacrylate (MMA) monomer andwidely used in dental medicine. It is primarily used for removable orthodontic, partial and full denture appliances, andalso for dental fillings. The facts and results of the previous studies showed that MMA might act as irritant in certainconcentration, and also as immunogen or allergen. This study examined the immunopathogenesis of oral mucosal tissuedestruction in patients exposed to MMA, by detecting the concentrations of plasma IL-4, IFN-Î³, TNF-Î±, serum IgG andIgE specific to MMA that mediated irritation and allergic reactions. The general objective of this research was to examinethe immunopathogenesis of oral mucosal tissue destruction in patients exposed to MMA. The study used observasionalcase control study design. Laboratory tests for all samples were assessing plasma IL-4, IFN-Î³ and TNF-Î± using directsandwich ELISA technique. Serum IgG and IgE specific to MMA were assessed by indirect ELISA. It was concludedthat MMA is immunogenic in patients exposed to MMA that can induce IgG anti-MMA. Furthermore, this study alsoproved that immunopathogenesis of oral mucosal tissue destruction in patients exposed to MMA did occur throughirritation and type I hypersensitivity reaction mediated by IgE, but occurred through type IV hypersensitivity reactions.
