Background: Orthodontic tooth movement occurred as a result of alveolar bone remodeling and collagen due to mechanical load. This mechanical load applied to the tooth will exert a number of cytokine and growth factors. One of the growth factors that are often associated with orthodontic tooth movement is transforming growth factor-β(TGF-β). It has 3 isoforms, TGF-β1, TGF-β2, and TGF-β3. It has been known that in adult patient, tooth movement rate was slower. Purpose: The aim of this study was to investigate the changing level of TGF-β2 in non-growing patient due to mechanical load in canine retraction. Method: Gingival crevicular fluid from 6 subjects who undergo canine retraction was taken to investigate changing level of TGF-β2. Distal site of each upper canine served as an experimental tooth. The gingival crevicular fluid from experimental tooth was taken just prior to mechanical load, at 24h and 72h after mechanical load. Result: ELISA reader showed that level of TGF-β2 was decreasing during experiment time. Conclusion: It can be concluded that in non-growing patient, TGF-β2 has less role in alveolar bone resorption in orthodontic tooth movement.

Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucous membrane which is characterized by unpredictable exacerbation and remission. The pathognomonic of oral features of OLP are hyperkeratotic striation surrounded white patches of mucosal erythema are called Wickham’s Striae. Chronic inflammation or epithelial damage of the mucous membrane often followed by candidosis as secondary infection. Candida species are commensal microorganism, its population in oral cavity reach 70% of the oral microorganism. It is harmless, but it could become opportunistic pathogen when the condition of oral environment support, i.e. decrease of oral immune response or the oral microorganism ecosystem change. This purpose of the paper was to report the case of a female patient (49 years old) who came to the clinic of Oral Medicine Faculty of Dentistry Airlangga University Surabaya with clinical and mycological evidence of thrush (Oral acute pseudomembrane candidosis). The patient not only suffered thrush, but also chronic cervicitis vaginalis. So the patient also consumed the antibiotic which was given by gynecologist. The used of the antibiotic for chronic servicitis vaginalis was the contrary treatment of oral thrush, after treated with nystatin oral suspention, clinical examination showed clearly hyperkeratotic lesion (Wickham’s striae), and hystopathological test result showed that it was OLP. The chronic oral inflammation and epithelial damage (OLP) or antibiotic consumption could inhibited the candidosis treatment. The case report suggested that the first treatment should be given antimicotic if the mycological test of candidosis showed positive result.

Background: Manufacturers supply alginate impression materials as a powder that is packaged in bulk and in individual container. Some Indonesian dental suppliers often repackage the bulk alginate into individual plastic packages which are not tied tightly and stored in the display room without air conditioner. It is known that critical factors to the shelf life of alginate includer avoidance of moisture contamination which may lead to premature setting of the alginate and avoidance of high temperature which may cause depolymerization of the alginate. Purpose: The aim of this study was to determine storage duration effect of repacked alginates on deformation recovery. Methods: Two brands of alginates (Tulip®TU, and Aroma Fine DF III®AF) were repacked into 120 plastic containers. The samples were stored in room condition (temperature 29° C ± 1° C, relative humidity 60% ± 10%) for 1, 2, 3, 4 and 5 weeks. The alginates setting time and recovery from deformation were measured according to the ANSI/ADA specification number 18 (ISO 1563). result: The results revealed that there was decreased setting time during 5 weeks but there was slight decreased in deformation recovery after 3 weeks storage. The ANOVA showed there was no significant difference of alginates deformation recovery among the storage times (p > 0.05). Conclusion: Storage duration of repacked alginates in plastic containers during 5 weeks in room condition do not influence the alginate deformation recovery.

The aim of this study was to determine the molecular changing of S.aureus, which is resistant to Ampicillin-Sulbactam and then become resistant to Methicillin as a result of improper dosage. The study was conducted by isolating Ampicillin-Sulbactam resistant and Methicillin Resistant S.aureus (MRSA), afterwards an amplification process was performed by PCR (Polymerase Chain Reaction.) to isolate the betalactamase enzyme regulator and PBP 2a genes. The result of this research showed that there were a deletion of few amino acids from the regulator gene, and a suspicion that the DNA sequence had been substituted from PBP 2 gene into PBP 2a (gen mec). This process had formed MRSA.

Background: The aesthetic has an important role in social life, especially the anterior teeth. The aesthetic abnormality of anterior teeth i.e. discoloration, malpotition or the anterior teeth with crown damage for more than one third or all part of crown is lost due to caries or other causes, will influence its appearance especially during smile. Purpose: The aim of this case report, therefore, is to show how teeth with clinical crown lost or only the root left still can be treated by endorestoration treatment in order to reconstruct the shape and function of the teeth similar to the original ones. Case: Female 52 years old with the lost crown of anterior teeth. The patient did not want her teeth to be extracted. Case Management: The abnormality of these teeth are still able to be reconstructed by endorestoration i.e. endodontic treatment with post and core insertion in the root canal will increase its retention and recovery by the porcelain crown fused to metal to recover the original formation and aesthetic and thus has the normal refunction. The treatment, it improve the confidence of the patient, and also can function normally. The patient did not feel pain. Ronsenography showed the periapical lesion diminished, the neighbor gingival was going better in both function and color. Conclusion: Endorestoration treatment on the anterior teeth with lost crown could recover the normal function, dental aesthetic and self confidence.

Background: In most cases of large periapical radiolucent lesions of pulpal origin, we often encounter a dilemmatic situation, such as whether to either treat these cases endodontically or surgically. Development of techniques, instruments and root medicaments as well as the tendency toward minimally invasive treatment, all support dentists to treat those cases using the minimal invasive principle (i.e. endodontically instead of surgically). Purpose: The purpose of this paper is to report and discuss the managing of periapical lesions by endodontic no invasive treatment. Case management: The patient with large periapical lesions were treated with noninvasive endodontic treatment. After 6 months, patients in this report were asymptomatic and radiolucencies had disappeared. When the root canal treatment is done according to accepted clinical principles and under aseptic condition, including cleaning, shaping, abturating as well as proper diagnosis, the healing process of the infected area will occur. Conclusion: Some lesions, however, may not be treated conservatively and may require surgical treatment for total elimination of the lesions.

Type II conventional glass-ionomer cements (GIC) are restorative materials consisting of powder and liquid mixed to produce a plastic mass that subsequently sets to a rigid solid. The early GIC was marketed without the expired date, although this material has been currently marketed with the expired date, how stable the materials are not yet clear. The purpose of this study was to evaluate the powder and the liquid GIC storage on the surface hardness of the samples. Six disc samples (5 mm in diameter and 3 mm thick) were made for each of four groups consisting of powder: aged liquid ages, aged powder: new liquid new, new powder new: new liquid new and aged powder: aged liquid ages respectively. All samples prepared followed the manufacturers’ recommendations and were allowed to set for 15 minutes then they were kept for 24 hours at room temperature before testing. Vickers microhardness was assessed for measuring the surface hardness at the top of the sample surface. The data were statistically analyzed using an ANOVA and LSD (p < 0.05). The results of this study indicated that the highest surface hardness was on the group of new powder: new liquid new = 52.040 VHN. The other groups were nearly similar, for new powder: aged liquid, aged powder: new liquid, aged powder: aged liquid they were 49.558 VHN; 49.123 VHN; 48.938 VHN respectively. Conclusion, powder and liquid of the type II conventional glass ionomer that had been stored for a long time descreased the surface hardness of the glass ionomer cements.

Background: One of the success criteria for a composite resin restorative material is the surface roughness that can be achieved through polishing. Considering that there are so many types of composite resin materials on the market, including polycrystalline composites, information on this type of composite’s surface roughness is needed. Purpose: The aim of this laboratory experiment was to compare the surface roughness difference between microhybrid and polycrystalline composite after polishing. Methods: In order to obtain this, a laboratory experiment was done. Four groups of composites were produced, the first two groups consist of microhybrid composite and the second two groups consist of polycrystalline composite. Two groups with the same material were treated with two different treatments as follows: the first group was not finished (the surface is under celluloid matrix), the second group was finished and polished. After these treatments, each sample’s surface was measured using surface roughness measuring instrument and then the Results: were analyzed statistically using independent t-test (α = 0.05). Conclusion: The result showed that after polishing, the surface roughness of polycrystalline composite is lower than that of microhybrid composite.
