Background: Traumatic ulcer is a lesion in oral mucosa as a result of physical and mechanical trauma, as well as changes in salivary pH. Jatropha multifida sap can act as antimicrobial, anti-inflammatory and re-epithelialization, and can also trigger the healing process of ulcers. Purpose: Research was aimed to determine the potential of Jatropha multifida sap against traumatic ulcer base on clinical and histopathological healing process. Method: This research was conducted laboratory experimental model, with rats (Rattus norvegicus) as the subject as well as Jatropha multifida sap for ulcer healing. Those subjects were divided into four groups: two treatment groups administrated with pellet and Jatropha multifida sap, one group as the positive control group administrated with 0.1% triamcinolone acetonide, and one group as the negative control group administrated with 0.9% NaCl. Ulcer manipulation was used 30% H2O2, and evaluation of ulcer healing was used clinical and histopathological approach. Result: Clinically, the healing process of ulcers in the treatment group with Jatropha multifida sap was faster than that in the positive control group with 0.1% triamcinolone acetonide, indicated with the reduction of the ulcer size until the missing of the ulcers started from the third day to the seventh one (p≤0.05). Histopathologically inflammatory cells (lymphocytes, and plasma cells) declined started from the third day, and the formation of collagen and re-epithelialization then occurred. On the seventh day, the epithelial cells thickened, and the inflammatory cells infiltrated. Statistically, those groups were significant (p≤0.05). Conclusion: Jatropha multifida sap has a significant potential to cure traumatic ulcers on oral mucosa clinically and histopathologically.

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.

Background: Cheilitis is a common problem of unknown etiology. A possible cause of cheilitis is contact allergy. Drugs, lipsticks, sunblock and toothpaste are the most common implicated allergens. Allergic contact cheilitis is a chronic superficial inflammatory disorder of the vermilion borders characterized by desquamation due to delayed-type hypersensitivity reaction. Purpose: We report a management of Allergic contact cheilitis due to lipsticks. Case: A 21-year-old woman had a history of atopic allergy to eggs, milk, and chicken presented with sore, dry, fissured, scaled and sometimes bleeding lip, over a 3-month period after application of a lipstick. Her symptoms persisted despite treatments with hydrocortisone cream. The patient provided a detailed history and underwent physical examination and patch tests to cosmetic components and patch test to her own lipstick. The patient had strongly-positive result to the tested lipstick. A diagnosis of allergic contact cheilitis was made based on the history and clinical findings. Case management: Patient was advised to avoid wearing lipstick. To relieve symptoms, treatment was initiated with combined topical corticosteroid, antibiotic, and moisturizer. Conclusion: Contact allergy patients should be tested for both cosmetic component series and their own lipsticks to exclude exfolliative cheilitis, infection, or light actinic cheilitis as causal agents.

Technology has continuously improved along with the complexity of devices. Nowadays, it is widely accepted that micro-technology, which is defined as a further reduction in the size of interconnections and components, is achieved by a conventional “top-down” method. We have now moved to a new concept and approach for fabrication from small to bigger building-block elements, which is called nanotechnology. Nanotechnology is the fabrication technology of tiny parts that is achieved by a “bottom-up” method. Nanotechnology has been developed in many areas of life sciences, such as in dentistry. This presentation provides some examples that illustrate the progress in technological growth, especially in the nanoscale. In the developments of nanotechnology, we are also concerned in many ways about its ethics and the laws of physics. The expansion in nanotechnology shows that much multidisciplinary research is being done in the nanoscale area. In dentistry, one of the examples is research in dental materials such as nanoleakage types in the use of various adhesives with resin composition. Nanodiagnostics are nanotechnology in applied molecular diagnostics. All these fields have applications in diagnostics and in point-of-care hand-held devices.

Background: Oral candidiasis is the most prominent oral fungal infection with Candida albicans (C. albicans) as 75% of ethiologic factor. Golden sea cucumbers (Stichopus hermanii) have been consumed by Asian community as folk medicine. It has been known to have antifungal and immunomodulator agent thus potential to be explored as treatment in oral candidiasis. Purpose: The aim of this study was to examine the potency of Stichopus hermanii extract as oral candidiasis treatment. Method: The study was an experimental laboratories research with post test only control group design. Thirty male wistar rats were divided into 5 groups i.e negative control, positive control and 3 treatment groups. Oral candidiasis condition were induced by spraying C. albicans suspension on dorsal tongue of wistar rats, once in 2 days for 14 days. The treatment groups were given Stichopus hermanii extract on the dose of 4.25 ml/kgBW, 8.5 ml/kgBW, 17 ml/kgBW once daily for 14 days. The expression of anti C. albicans antibody and TNF-α were examined by immunohistochemistry on ephitelial tongue. Data was analyzed by Manova and LSD test. Result: Anti C. albicans antibody expression were higher in positive control group than in negative control group while TNF-α expression were lower in positive control group than in negative control group (p<0.05). Treatment with Stichopus hermanii extract on all doses decreased the expression of anti C. albicans antibody and increased the expression of TNF-α (p<0.05). Conclusion: Stichopus hermanii extract decreased the expression of anti C. albicans antibody and increased the expression of TNF-α in epithelial rat tongue.

Three different dental implant placements according to surgical implant bed situations were observed in its bone integration 3 months after dental implant insertion. This observation was done on implant system which has plateau or fin system. Elf implants were placed in the upper jaw in two patients. In case one, two implants were inserted immediately after tooth extraction, and the other six implants were placed in the alveolar crest regions in delayed implantation or in which the teeth had been extracted over 6 months of period. In case two, three implants were inserted in the post trauma region in the anterior maxilla, which the labial plate had been lost and reconstructed with bone grafting procedure using a mixture of alloplastic and autogenous bones. The alveolar reconstruction was needed to be performed due to only thin alveolar crest width was left intact. All of those implants observed showed in good integration.

Bond strength between 2-Hydroxyethyl methacrylate HEMA-based dentin bonding agent and dentin collagen had proved by presence of the chemical interaction. This union involved the carbonyl group on HEMA resin with amino group on dentin collagen following produce an amide chain. However, this bond strength influence by humidity condition of dentin collagen and HEMA resin. The aim of this study is to measure the effect of humidity on peak value of the HEMA carbonyl absorbance band. The bond strength between by HEMA bonding agent and dentine collagen was analyzed in different humidity, e.g. in 60%, 70%, 80%, and 90% humidity. Control experiment was done in ambient room humidity that is 65%. Chemical bond that formed between HEMA and dentine collagen was carried out by mixing pure HEMA with bovine type-I collagen which had been stored in different humidity. The esther carbonyl group of HEMA will react with the amino group of collagen, produced an amide bonding, which is observed by measuring the IR spectrum absorbance of the esther carbonyl group of HEMA in KBr method. The decrease of the carbonyl group absorbance indicates the more chemical bonds formed. By measuring the absorbance of C=O esther in different humidity, it showed that the greatest number of chemical bonds resulted when the experiment was done in 70% humidity condition.

Background: Epulis or epulides are lesions associated with gingival tissues. Fibrous epulis is a type of hyperplastic fibrous tissue mass located at the gingival which is slow growing, painless, having same color as the oral mucosa and firm on palpation. Anterior regions of the oral cavity are the frequently affected sites as these areas are more prone to be affected by calculus deposition and poor plaque control due to frequent teeth malposition. Removal of any irritating factors and excision of the lesion are the usual treatments. Purpose: This case report presents a rare case of fibrous epulis which occurred in the posterior region of the oral cavity and associated with impacted lower third molar. Case: A case of fibrous epulis at the lower right third molar area of three months duration is presented. The mass was slow growing, painless and on examination it was a pedunculated mass overlying the unerupted lower right third molar, having same color with the oral mucosa and firm on palpation. Clinically, the lesion was diagnosed as fibrous epulis associated with impacted lower right third molar. Case management: The treatment were surgical excision of the epulis and removal of the lower right third molar. The histopathology result showed tissue with squamous epithelial lining, achanthotic fibrous connective tissue, mononuclear inflammatory cells and few capillaries without signs of malignancy. This is consistent with the diagnosis of fibrous epulis. Conclusion: Fibrous epulis, although frequently occurred at the anterior region of the oral cavity, may rarely grow at the area of lower third molar. This phenomenon supports the theory that epulis can grow on any surface of oral mucous membrane as long as local irritants are present.

Background: Wound healing involves cellular, molecular, physiological, and biochemical processes as responses to tissue damage. For instance, when a failure during tooth extraction occurs, radiographic examination, X-rays, is required. X-rays as an enforcer diagnosis can damage DNA chain, resulting in cell death and inhibition of wound healing process. Purpose: This research aims to analyze fibroblasts cell number and fibroblast growth factor-2 (FGF-2) expressions during wound healing process after tooth extraction as a result of X-ray irradiation. Methods: There were three research groups, each consisting of ten rats. Incisor tooth extraction was performed on the left lower jaw, and then X-ray examination was conducted at certain irradiation doses, namely 0 mSv, 0.08 mSv, and 0.16 mSv. Those animals were sacrificed on day 3, and on day 7 after the extraction, histopathology and immunohistochemistry examinations were conducted to determine fibroblast cell number and FGF-2 expressions. Data obtained were then analyzed by oneway ANOVA and Tukey HSD tests. Results: The number of fibroblasts decreased significantly in the group with the irradiation dose of 0.16 mSv applied on day 7 after the extraction (p <0.05). Similarly, the number of FGF-2 expressions decreased significantly in the group with the irradiation dose of 0.16 mSv applied on days 3 and 7 after the extraction (p <0.05). Conclusion: X-ray irradiation at a dose of 0.16 mSv can inhibit the healing process of tooth extraction wound due to the decreasing of fibroblasts cell number and FGF-2 expressions.
