Coral has been used as a bone substitute in many experimental studies. It has been proven to be biocompatible, biodegradable and easy to handle: and it has not been found to cause any inflammatory responses. The present study was undertaken to determine the cytotoxicity in terms of mitotic index as well as the clastogenic effect (chromosome aberration) of sea coral implantation in rabbits. The animals comprised of five male adult healthy New Zealand White (Oryctolagus cuniculus) rabbits. The biomaterial, sea coral granules used in this study was obtained from Porites species and processed by the tissue bank of Universiti Sains Malaysia, Health Campus, Kubang Kerian, Malaysia. The blood samples were collected twice from the rabbits, once before the implantation of the sea coral granules (which acted as the control) and the other, one week after the implantation (which acted as the treatment) and lymphocyte cultures were set up. The cultures were then harvested and the chromosomes were prepared for analysis. The diploid number of chromosomes in the rabbits (Oryctolagus cuniculus) was found to be 44. Mean mitotic indices of 3.84 ± 0.54 per cent and 3.76 ± 0.23 per cent were obtained before and after implantation of sea coral granules respectively. There were no structural or numerical chromosomal aberrations observed in both the cases. The mitotic index values and chromosomal analyses in this preliminary study carried out indicate that the biomaterial, sea coral granules is non-cytotoxic and non-clastogenic under the present test conditions.

Background: Indonesia is a tropical country with temperature variation. A lot of dental clinics do not use air conditioner. The room temperature influences water temperature for mixing alginate impression materials. Purpose: The aim of this study was to investigate the functional relationship of room temperature and initial setting time of alginate impression materials. Methods: The New Kromopan® alginate (normal and fast sets) were used. The initial setting time were tested at 23 (control), 24, 25, 26, 27, 28, 29, 30 and 31 degrees Celcius room temperatures (n = 5). The initial setting time was tested based on ANSI/ADA Specification no. 18 (ISO 1563). The alginate powder was mixed with distilled water (23/50 ratio), put in the metal ring mould, and the initial setting time was measured by test rod. Data were statistically analyzed by linear regression (α = 0.05). result: The initial setting times were 149.60 ± 0.55 (control) and 96.40 ± 0.89 (31° C) seconds for normal set, and 122.00 ± 1.00 (control) and 69.60 ± 0.55 (31° C) seconds for fast set. The coefficient of determination of room temperature to initial setting time of alginate were R2 = 0.74 (normal set) and R2 = 0.88 (fast set). The regression equation for normal set was Y = 257.6 – 5.5 X (p < 0.01) and fast set was Y = 237.7 – 5.6 X (p < 0.01). Conclusions: The room temperature gave high contribution and became a strength predictor for initial setting time of alginates. The share contribution to the setting time was 0.74% for normal set and 0.88% for fast set alginates.

The purpose of this study was to compare cross-national differences of the recognition of denture adhesive among dentists. The design of the research was cross-cultural differences. The research was done in Japan and Indonesia. One hundred and ten dentists from Japan and Indonesia were surveyed using a questionnaire regarding knowledge/comprehension of denture adhesive (in Japanese and Indonesian versions respectively). Logistic regression model (forward stepwise method) showed that it was possible to distinguish Japanese dentists from Indonesian peers with a probability of 96.0 per cent by using 4 items out of 16. For the question of "How many domestic products of denture adhesive (DA) do you know?" approximately a half of the Japanese dentists answered "less than 3", whereas 93 per cent of Indonesian subjects answered "nothing". It was concluded that there were much differences in dentists' understanding and experience of denture adhesive in the clinic, between Japan and Indonesia.

Background: Traumatic injuries to the oral mucosa in fixed orthodontic patients are common, especially in the first week of bracket placement, and occasionally lead to the development of aphthous stomatitis or ulcers. Nevertheless, these lesions are selflimiting. Purpose: The objective of this study is to reveal the connection between chronic gingivitis and aphthous stomatitis which is still unclear. Case: A patient with a persistent lesion for more than six months. Case Management: RAS was treated with scaling procedure, the gingival inflammation was healed. However, in this case report, despite the appropriate management procedures had been done, the lesion still worsen and became more painful. Moreover, the symptoms did not heal for more than two weeks. Actually, they had been undergone orthodontic treatment more than six months and rarely suffered from aphthous stomatitis. Coincidentally, at that time they also suffered from chronic gingivitis. It was interesting that after scaling procedures, the ulcer subsides in two days. Conclusion: Recently, the neuroimmunobiological researches which involved neurotransmitters and cytokines on cell-nerve signaling, and heat shock proteins in gingivitis and stomatitis are in progress. Nevertheless, they were done separately, thus do not explain the interrelationship. This proposed new concept which based on an integrated neuroimmunobiological approach could explain the benefit of periodontal treatment, especially scaling procedures, for avoiding prolonged painful episodes and unnecessary medications in aphthous stomatitis. However, for widely acceptance of the chronic gingivitis and aphthous stomatitis relationship, further clinical and laboratory study should be done. Regarding to the relatively fast healing after scaling procedures in this case report; it was concluded that the connection between chronic gingivitis and aphthous stomatitis is possible.

Streptococcus mutans (S. mutans) are regarded as the main initiator microorganism of caries, with Lactobacilli participating on caries progression, due to its carcinogenic capacity. The purpose of this study was to examine the number of S. mutans and Lactobacillus sp in children with in children’s saliva with dental caries and free caries. Twenty children attending the Paediatric Dental Clinic in Airlangga University participated in our study. Their age ranged from 1–14 years old. Subject was divided into two groups, which were study group consisting of 10 children with 3–5 dmft/DMFT and control group with 10 caries free children. Subjects were examined and their caries number was recorded using WHO index. Stimulated saliva was collected from each subject for bacterial assessment. Colony counting of S. mutans and Lactobacillus sp count in each saliva sample group were done. The study showed that subject with 3–5 dmft/DMFT had higher number of S. mutans and Lactobacillus sp than caries free.

Pulpitis is an inflammation process on dental pulp tissue, and usually as the continuous of caries. The microorganism in the caries is a potential immunogenic triggering the immune respons, both humoral and celluler immune responses. The aim of this research is to explain the humoral immune response changes in the dental pulp tissues of pulpitis. This research was done on three group samples: Irreversible pulpitis, Reversible pulpitis and sound teeth as the control group. The result showed that there were three pulpitis immunopathologic patterns: the sound teeth immunopathologic pattern showing a low humoral immune response, in a low level of IgG, IgA and IgM, the reversible pulpitis pattern showing that in a higher humoral immune response, IgG and IgA decreased but IgM increased, the irreversible pulpitis pattern showing that IgG and IgM increased, but it couldn't be repaired although it has highly immunity, and it showed an unusually low level of IgA. This low level of IgA meant that irreversible pulpitis had a low mucosal immunity.

Ideally in orthodontic tooth movement, alveolar bone will follow its movement, therefore, the ratio between bone remodeling and tooth movement is 1:1. The problem whether the ratio is valid for all kinds of tooth movement such as: tipping, torquing, or bodily, or it could be applied in tooth movement of all directions such as facially, lingually or sagitally. Various studies also showed many different ideas. Some studies state that root dehiscence and fenestration are frequently found in final orthodontic treatment and some other state that bone remodeling can compensate tooth movement. The purpose of this study was to know the changes of alveolar bone morphology caused by anterior tooth movement. The conclusion is remodeling compensation is not matched with the extension of tooth movement, thus there are many cases of root dehiscence and fenestration after orthodontic treatment.

Different types of fibers have been added to acrylic resin materials to improve their mechanical properties. The purpose of this study was to know the transverse strength of the hybrid acrylic resins after glass fiber reinforcement with difference method. This study used rectangular specimens of 65 mm in length, 10 mm in width and 2.5 mm in thickness. There were 3 groups consisting of 6 specimens each, hybrid acrylic resin without glass fiber (control), glass fibers dipped in methyl methacrylate monomer for 15 minutes before being reinforced into hybrid acrylic resin (first method), glass fibers reinforced into a mixture of polymer powder and monomer liquid after the hybrid acrylic resin was mixed directly (second method). All of the specimens were cured for 20 minutes at 100° C. Transverse strength was measured using Autograph. The statistical analyses using one way ANOVA and LSD test showed that there were significant differences in transverse strength (p < 0.05) among the groups. The means of transverse strength were 94,94; 118,27; and 116,34 MPa. It meant that glass fibers reinforcement into hybrid acrylic resin enhanced their transverse strength compared with control. Glass fiber reinforcement into hybrid acrylic resin with differenciate method didn’t enhance their transverse strength.
