Diabetes Mellitus (DM) is a chronic disorder of carbohydrate, fat and protein metabolism. A defective or deficient of the insulin secretory, which is translated into impaired carbohydrate (glucose) use, is characteristic feature of DM, as the resultant is hyperglycemia. There is variability among patients, however, morphologic changes are likely found in arteries (atherosclerosis), basement membrane of the blood vessel wall tissues (micro angiopathy), kidneys (diabetic nephropathy), retina (retinopathy), nerves (neuropathy) and other tissues. If it involves salivary glands, the clinical sign is xerostomia. The type 2 of DM is caused by a combination of peripheral resistance to insulin action and an inadequate secretory response of the pancreatic b-cell. Approximately 80% to 90% of patients have type 2 diabetes. The purpose of this study was to determine the prevalence of xerostomia and its relation with level of blood glucose in type 2 DM. The data was taken using cross sectional method on the diabetic patients of Internal Medicine clinic, Hajj Hospital Surabaya from February to March 2006. The result that showed among 50 samples of the type 2 DM, the prevalence of xerostomia were 38 patients (76%). Most of the patients (32 patients = 84%) on bad regulation of DM with level of fasting glucose ≥ 126 mg/dl and level of post prandial glucose ≥ 180 mg/dl. The study showed that bad regulation of type 2 DM could develop complication on salivary glands, with xerostomia as the clinical sign.

; "> The relationship between oral health and systemic diseases had been abundantly studied, however, mostly were related to adultsuch as cerebrovascular disease, cardiovascular disease, diabetes mellitus etc. Nevertheless, it was still uncommon that oral healthalso related to allergic disease. The field of pediatric dentistry is mostly related to preventive dentistry (i.e. prophylactic procedures,preventive orthodontic etc., but rarely related to preventive medicine such allergy prevention in children. Allergic diseases develop outof a close interaction between genetic predisposition and environmental triggers, and progress continuously since infancy regarding tothe allergic march. Concerning to the partially developed immunity in children, children are more susceptible to infection and allergicdiseases than adults. Unfortunately, infection and allergic diseases are interrelated; infection impaired allergy and vice versa. Poororal health is closely related to infection; however, improving oral health is not included in allergy management protocol. In order toanticipate the future, dentist or especially pediatric dentist should be able to review about basic children immunity and oral mucosalimmunity. Additionally, it is essential to explain to the parents and medical practitioners who are not familiar to this new paradigm.The objective of this study is to review articles related to children’s oral health and allergic symptoms. Regarding to the successfuloral management of allergic symptoms, the propensity that improving oral health could be included in children’s allergy managementprotocol is likely.

The new fourth generation electronic apex locator (EAL), Elements (SybronEndo, USA) has been introduced recently in the market. This study aims to investigate the accuracy of this EAL and to compare the result with a well-known apex locator, Root ZX and the radiographic technique using an in vitro model. Thirty anterior teeth with straight canals stored in 10% formalin were used. Access cavities were prepared followed by coronal flaring of the canals. Water was used as an irrigant. After the actual lengths (AL) were measured, the teeth were then embedded in an alginate model. Periapical radiograph of each tooth was taken using a digital sensor and the radiographic lengths (RL) were measured 0.5 mm short of the radiographic apex. Electronic tooth length measurements (EL) were carried out using both EAL. Canals were then irrigated with 2.5% NaOCl and EL was taken again. Results showed that both EALs were highly accurate to within + 0.5 mm of the apical foramen, with mean differences between the AL and EL of Elements 0.23mm (SE = 0.04) and Root ZX was 0.31mm (SE = 0.05). RL was significantly less accurate compared to the readings from both EAL. No significant difference was found in the reading between both apex locators when measurements were taken in NaOCl solution. Both Elements and Propex proved to be as reliable as Root ZX. Presence of sodium hypochlorite solution did not affect the accuracy of the measurements.

Oral squamous cell carcinoma (OSCC) is the result of accumulation genetic lesion and caused by specific mutation in specific key regulation genes. p53 gene is key target specific regulatory genes which function as negative regulators in cell cycle control. The highest mutation rates found in human cancers and the etiology in high risk populations and the pattern of molecular pathogenesis mechanism involved in the OSCC remain unclear. The purpose of this study was to determine the presence of alteration or mutation of p53 gene and to associate these mutations histopathological status of the patients such as well differentiated and poorly differentiated in OSCC in order to elucidate the molecular pathogenesis mechanism of OSCC based on the pattern of p53 gene. Using 40 untreated well and poorly differentiated OSCC biopsy samples and 16 normal patients were analyzed for the presence of mutation in the conserved region of the p53 gene exons 5 and or 7 by PCR-SSCP mutational analysis for p53 gene showed 70% of total samples : exon 5: 27.5% with heterozygous mutation 81.8%, exon 7: 55% with heterozygous mutation 100%. The incidence of p53 mutation was not significantly associated with well and poorly differentiated OSCC with the exception in exon 5 of p53 gene (p = 0.013) using contingency coefficient. This study concludes that mutation of p53 gene especially in exon 7 may not indirectly play in the progressivity of OSCC with the exception of mutation in exon 5 of p53 which indicates the essential role in the progressivity of OSCC.

Total etch dentin bonding agents had been used extensively in operative dentistry. These materials were used on dentin surfaces before application of the resin adhesive restorative. The purpose of this research was to prove the difference of tensile bond strength between total etch and self etch dentin bonding agent on dentin surface. The manner of preparing total etch dentin bonding agent was : bovine dentin as sample was grounded to give flat surface which was then etched with 37% phosphoric acid for 15 seconds, washed with 20 ml water and dried with blot dry technique. Sample was placed in a desiccator for one hour 60% humidity covered with bonding agent and put into tensile tool plunger and stored at room temperature (± 28 °C) for 24 hours. Sample was tested using Autograph instrument. The manner of preparing self etch dentin bonding was equal with total etch manner but without acid etching, washing and drying. The data analyzed using One-Way ANOVA test at α = 0.05 and followed Tukey HSD test. The result indicated that the tensile bond strength of total etch was higher than self etch dentin bonding at 60% humidity (p ≤ 0.05). In conclusion, the total etch dentin bonding agent with acetone solvents have a higher tensile bond strength compared with self etch dentin bonding agent also with dentin bonding in alcohol solvents.

Hydroxyapatite (HA) is the most thermodynamically synthetic calcium phosphate cement, and has indicated useful as a sealer because can seal a furcation perforation, is shown to be biocompatible and also has potential to promote the healing of bone in endodontic therapy. The objective of this study is to determine the sealing ability of HA produced by School of Engineering, Universiti Sains Malaysia (USM) when used as a sealer in root canal obturation, compare with Tubli-seal (Zinc-Oxide base) and Sealapax (Calcium Hydroxyde base) sealers. Forty five single rooted human anterior teeth were instrumented and randomly divided into three experimental groups of 15 teeth each. All teeth in the experimental groups were obturated with laterally condensed gutta percha technique. Teeth in the first group were sealed using Zinc-Oxide (ZnO) based sealer and those of second group using Calcium Hydroxide (CaOH) based root canal sealer. Third experimental group was sealed using HA from School of Engineering USM. Teeth were then suspended in 2% methylene blue. After this, teeth were demineralized dehydrated and cleared. Linear dye penetration was determined under magnifying lense with calibrated eye piece. Statistical analyses of the linear dye penetration were performed with Kruskal Wallis test. The intergroup comparison between HA and ZnO groups and CaOH groups were analyzed by Mann-Whitney test. The dye penetration for group which were sealed with HA exhibited the lowest penetration and it showed that there was a statistically significant difference both between HA and ZnO groups and also between HA and CaOH groups (p < 0.001).In conclusion, it was found that value added HA based endodontic material which were produced by USM can be used as a root canal sealing materials when it used in combination with epoxy resin since it leaked comparatively less as compared to ZnO and CaOH sealers. Before reaching a definitive conclusion, this material requires further extensive exploration both clinically and in vitro.

Rigid restoration is attached within oral cavity using adhesive cement layer. The hardening adhesive cement fills and tights the rough tooth surface with reciprocal opposing restorations. The luting type of glass ionomer cement was mostly used in the clinic for crown cementation as well as poured restoration. We can be taken a problem how strong is antibacterial effect of the luting type of glass ionomer cement to Lactobacillus species and Streptococcus Mutans. The purpose of the research was to know the antibacterial force of the luting-type of glass ionomer cement toward Lactobacillus species and Streptococcus mutans. This research was a laboratory experiment. The samples of the research were divided into two groups, treated-group (Fuji and Shofu) and controlled-group. The numbers of samples in each group consisted of 7 pieces. Taking 0,5 ml of artificial saliva in which the sample of the luting-type of glass ionomer cement (5 mm in diameter and 2 mm thick) had been immersed and storing it into Petri dish containing warm MRSA and 0,1 ml Lactobacillus sp. using poured technique. The mixture was subsequently incubated, and the colony was counted on the observation of 1st day, 7th day, and 14th day. The data were analyzed using ANOVA and LSD. The result of the research showed that the greatest mean value of the bacterial colony presented in the controlled-group and the smallest was in the group of Shofu. Statistical analysis showed a significant difference (p < 0.05). The released fluoride from glass ionomer cement occurred in the damaging phase caused by polyacrylate that released H+ ion from carboxyl group (COOH). The fluoride influenced the growth of bacteria by decelerating the activity of gycolytic enolase enzyme. The luting-type of glass ionomer cement had antibacterial force toward Streptococcus mutans and Lactobacillus sp. The luting-type of glass ionomer cement of Shofu possessed greater antibacterial force than Fuji and controlledgroup.
