The purpose of this study was to investigate the three dimensional changes in the fitting surface and artificial teeth of maxillary complete dentures which were fabricated using two different polymerizing processes: heat polymerization (HP) and microwave polymerization (MP), after immersion in water for seven days. The amount of distortion in the molar region of the alveolar ridge was significantly different between HP and MP. However, the overall distortion of the dentures polymerized using both methods was similar. The distortion due to immersion in water for seven days compensated for the polymerization distortion, but the amount of distortion was very slight.

Functional and aesthetic dysgnathia surgery requires accurate pre-surgical planning, including the surgical technique to be used related with the difference of anatomical structures amongst individuals. Programs that simulate the surgery become increasingly important. This can be mediated by using a surgical model, conventional x-rays as panoramic, cephalometric projections and another sophisticated method such as a three dimensional computed tomography (3 D-CT). A patient who had undergone double jaw surgeries with difficult anatomical landmarks was presented. In this case the mandible foramens were seen highly relatively related to the sigmoid notches. Therefore, ensuring the bone incisions in sagittal split was presumed to be difficult. A 3D-CT was made and considered to be very helpful in supporting the pre-operative diagnostic.

Tamarindus indica is one of traditional medicines. Pulpa tamaridorum consist of organic acid that is usually used as irrigant and to remove root canal wall smear layer. The aimed of this study was to elucidate the ability of 5% Tamarindus indica extract as a root canal irrigant to remove root canal wall smear layer. Eighteen tooth samples were cut on cervical line and divided into 2 then groups were prepared with K file and irrigated. Group 1 was irrigated by sterile aquabidest and group 2 was irrigated by 5% Tamarindus indica extract. Samples were cut longitudinally and formed 7 × 2× 2 mm specimen. Each specimen was photographed by scanning electron microscope, scored and summed. The total score obtained is used as the hygiene value of root canal wall. The collected data were statistically analyzed by using independent t test at 0.05 level. The result of the study showed there was a significant difference between 5% Tamarindus indica extract and sterile aquabidest (p < 0.05), the hygiene value of 5% Tamarindus indica extract was higher than sterile aquabidest. The conclusion of this investigation showed that 5% Tamarindus indica extract remove root canal wall smear layer.

Background: Spirulina which grows abundantly in tropical seas have been investigated to enhance immune system. The administration of spirulina in tooth extraction sockets was expected to optimise the function of immunocompetent cells. Therefore, wound healing process would be improved. Purpose: The aim of this study was to prove that administration of spirulina could influence immune system in tooth extraction sockets. Method: There were 28 Cavia cobayas used in this study and were put in group of four. Mandibular left incisive were extracted from each of them. The basis made from mixture of polyethylene glycol (PEG) 400 and PEG 4000 was administrated into each socket in control group (TG0). In addition, spirulina 12% was administrated into group TG1, spirulina 24% was administrated into group TG2, and spirulina 48% was administrated into group TG3. All of the Cavia cobaya were decapitated and the jaws were removed in day 5 after tooth extraction. The jaws were decalcified in EDTA solution, formed into paraffin block, processed for hematoxylin and eosin (H & E) and immunohistochemistry staining afterwards. Datas were analysed statistically using Anova method. Result: There was an augmentation in the number of macrophages and activated plasma cells after spirulina application. The administration of higher concentrations of Spirulina leads to greater amount of macrophages and activated plasma cells in each groups. Conclusion: In conclusion, spirulina is able to increase the amount of macrophages and activated plasma cells which play important role in healing process.

The purpose of this study was to measure and compare two different polymerizing processes, heat polymerizing (HP) and microwave polymerizing (MP), on the three dimensional changes in the fitting surface and artificial teeth of maxillary complete dentures. A threedimensional coordinate measurement system was used to record distortion of the specimens. The distortion of the fitting surface was measured from the reference plane on the fitting side from which a coordinate system was set, and the movement of the artificial teeth and the distortion of the polished surface was measured from the reference plane of the artificial tooth side, from which a coordinate system was set. It was clearly showed that various distortions of denture specimens after polymerization process can be measured with this three-coordinate measuring machine. The study showed that the overall distortion of the fitting surface in HP specimens was shown to be larger than in MP ones.

Oral habits, comprising of thumb and lip sucking, lip and nail biting, tongue thrusting and mouth breathing are commonly caused by disturbance in mental development. These persistent habits may lead to disturbance in physical growth, causing disorders such as malocclusion. Homeless children are prone to this condition. The purpose of this descriptive research was to present the prevalence of oral habits in homeless children under care of Yayasan Bahtera Bandung, by survey technique. The sample consisted of 92 children collected by purposive sampling. This research was conducted through interviews and clinical examnations of the oral cavity to elucidate signs of oral habits. The result showed 50% of homeless children performed oral habits, consisting of 26 boys (55,32%) and 20 girls (44.44%). The prevalence of thumb sucking habit was 21.74%, lip sucking or biting was 17.37%, tongue thrusting was 4,35%, nail biting and mouth breathing tied at 3,26%. The research concluded that a part of homeless children had oral habits, with boys as slight majority, and thumb sucking was the most performed.

The habit of nocturnal bottle or breast-feeding has been reported to be a potential cause for early childhood caries (ECC) in very young children. The aim of this study was to determine the prevalence of ECC in children 2-5 years of age attending out patient clinic HUSM, in relation to the nursing habits. In this cross-sectional study, 90 children were randomly selected to examine their caries status using torch and disposable mirror. Data on mothers’ educational level, nursing habits and oral hygiene practices, were gather by using structured questionnaire. It has been found that 16.7% of subjects were caries free while 83.3% of them had caries with mean dmf score 6 (SD 5.3). With regard to nursing habits, 29% of subjects had breast-feeding alone, 16% had bottle-feeding alone and 55% had both breast and bottle-feeding. Ninety-three percent of children had been nursed beyond 14 months and 47% had been fed with liquids other than breast milk, infant formula or water. Twenty-seven percent of children were allowed to sleep with nursing bottle in mouth and 52% were allowed to sleep with breast nipple in the mouth which shows significantly associated with ECC (p = 0.03). Tooth brushing habit was reported for 91% of children using toothpaste. Mean age of the children (in months) when the mothers started brushing the teeth was 19.1 (SD 10.8) and has significant association with ECC (p < 0.05). This study demonstrates that the habit of allowing infants to sleep with breast nipple in their mouth and the late start of tooth brushing are associated with prevalence of ECC. Educational programs for pregnant women and mothers of young children should be emphasized to enhance the knowledge and awareness of mothers in preventing ECC.

Background: The use of orthodontic indices were increasingly popular in the last few years. Index of Orthodontic Treatment Need (IOTN) usually was used to assess the needs and demand of orthodontic treatment, eventhough, indices can be used for more than one purpose. Purpose: To determine whether the Index of Orthodontic Treatment Need (IOTN) could be able to evaluate the treatment results as well. Method: Data was obtained by evaluating each of 202 study models from 17 Orthodontic Postgraduate students. The ‘before’ and ‘after’ treatment models were assessed, using the Index of Orthodontic Treatment Need. Result: Using the Wilcoxon Signed-Rank test, the assessment of Dental Health Component (DHC) and Aesthetic Component (AC), before and after orthodontic treatment showed significantly differences from each others (p : 0,000 < α : 0.05). The Null hypothesis were rejected. The grade of DHC and AC were decreasing to a better score. Conclusion: The Index of Orthodontic Treatment Need (IOTN) could be used to assess the orthodontic treatment outcomes, to evaluate before and after orthodontic treatment of the patients. The results of the treatment showed good improvements of dentofacial appearance of the patients which means the successful achievement of the clinical works programs.

Since etching is completed at the same stage as priming and bonding, when applying the sixth and seventh generation bonding, the exposed smear layers are constantly surrounded by primer and bonding and cannot collapse. The smear layer and the depth of penetration of resin bonding in dentinal tubules are completely integrated into hybrid layer. The purpose of this laboratory research was to study the penetration depth of two self etching adhesive. Fourteen samples of human extracted teeth were divided into two groups. Each groups consisted of seven samples, each of them was treated with sixth generation bonding agent and the other was treated with seventh generation bonding agent. The results disclosed that the penetration into dentinal tubules of seventh generation bonding agent was deeper than sixth generation bonding agent. Conclusion: bond strength will improve due to the increasing of penetration depth of resin bonding in dentinal tubules.

Background: It is known that oral squamous epithelial dysplasia (SED) and carcinoma in-situ (CIS) are precancerous lesion and it could transform to squamous cell carcinoma (SCC). We had reported p53-Protein Over-Expression and Gene Mutational of Oral CIS, such as basaloid, verrucous, and acanthothic/atrophic types, but demarcated between SED to CIS and CIS to SCC and how their transformation is still unclear. It is considered that their molecular behavior related one another. Purpose: To understand the molecular behavior of them we examined p53 exon 5-8 gene mutation and their protein expression in the sequential cases. Methods: Using 10 cases formalin–fixed paraffin sections that composed SED appearance, CIS and SCC in the same case were subjected to P53 immunohistochemistry. Then all cases were subjected to p53 gene mutations analysis. By laser capturing microdissection dysplasia part, CIS part and SCC part were cutted, and followed by direct sequencing of PCR product for exon 5-8. Result: SED p53-protein over-expression in some cells, and the expression was increased to CIS and SCC. Mutational analysis for p53 gene showed that 60% of p53 gene mutation in CIS also found in SCC, therefore SCC had additional mutation in other exon of p53 gene. While no particular mutations were found in SED part of all cases. Conclusion: Carcinoma in-situ is a squamous cell carcinoma eventhough not invasive yet, but squamous epithelial dysplasia is an early step to malignancy. It needs other genes examination to know any genes are involved in the precancerous to cancer transformation process.
