Introduction. Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. These tumors are formed from enamel and dentin, and can have variable amounts of cement and pulp tissues. According to radiographic, microscopic, and clinical features, two types of odontomas are recognized: Complex and compound odontomas. Complex odontomas occur mostly in the posterior part of the mandible and compound odontomas in the anterior maxilla. Case Report. A young girl patient, 9 years old came to Department of Oral and Maxillofacial Surgery with a slow growing and asymptomatic swelling in her left posterior mandible for 5 years in his history taking. The panoramic radiograph show a radioopacity and radiolucent lesion at the lower second molar region, with well-corticated limits. An insisional biopsi confirmed as compound odontoma. The surgery performed with simple enucleation and curettage under general anaesthesia. Discussion. Compound odontomas are usually located in the anterior maxilla, over the crowns of unerupted teeth, or between the roots of erupted teeth. In this case report, Compound odontomas are found in the posterior mandible. Conclusion. Compound odontomas in the posterior mandible is a rare. The treatment of odontomas depends on the size of the lesion. The early diagnosis, the treatment of choice is conservative surgical enucleation and curettage and prognosis is excellent.

The surface hardness level of a denture base material is related to the resistance to abrasion, scratch, polishing and water sorption. Nowadays, thermoplastic nylon resins and heat-cured acrylic resins are used as denture base materials. Denture base must be immersed in water to maintain its humidity. The objective of this research was to compare the surface hardness level between thermoplastic nylon resins and heat-cured acrylic resins. Materials used for the research were thermoplastic nylon resins from Valplast and heat-cured acrylic resins QC-20, with a sample size of 64x(10±0.03)x(2.5±0.03) mm. Surface hardness is measured with Vickers Microhardness Tester and the data were analyzed by ANOVA method. The results showed that comparison ratio of surface hardness level between thermoplastic nylon resins and heat-cured acrylic resins before immersion is 3.2:7.3 VHN respectively, while the comparison value of both resins after immersion is 2.8:6.6 VHN. In conclusion, the surface hardness level of thermoplastic nylon resins is lower compared to heat-cured acrylic resins. This result is due to thermoplastic nylon resin’s higher porosity, its different polymer chains, and the plasticizers effect after immersion in water.

Introduction: Lipid peroxidation, one of the known indices of oxidative stress, is documented in various diseases. Secondary oxidation products such as malondialdehyde (MDA) is commonly measured to observe lipid peroxidation. In this study, a spectrophotometric method was evaluated to measure thiobarbituric acid reactive substances (TBARS) with high sensitivity. This study was aimed to optimisation standard of MDA using tetraethoxypropane (TEP) 97% (FW=220.3). Methods: The method is based upon the reaction of malondialdehyde (MDA) and TBA in the glacial acetic acid medium. MDA is a known biomarker of oxidative status in a biological system. This research consists of two phases: first, making a stock of TEP, and the second phase was testing the concentration of TEP for finding the standard curve of MDA before used in diagnostic of lipid peroxidation. Results: Result showed the concentration 1,875-60 uM of TEP could form a precise standard curve. Conclusion: This concentration of TEP can be used as a reference as the standard of control in diagnostic of lipid peroxidation using TBARS method.

Root canal treatment diagnoses as pulpitis irreversible can be treated in a non-vital condition with devitalization material. Arsenic is one of devitalization material that used in inflammatory pulp tissue before it is going to endodontic treatment. The long-term use of it or the leak of using this arsenic can cause the toxic effect of the pulp tissue. The case is going to report is about the damage of gingival tissue and alveolar that caused by the uncarefullness using of arsenic. Inappropriate arsenic applications cause the leak that able to spread to gingival tissue and will become necrosis. Now a day, the using of arsenic begin to leave because of the toxicity sad effect. This report is going to report how much the damage using arsenic trioxide (As2O3) and the effort from the leakness.

Lichen planus is a common oral disorder which may represent the manifestation of varies clinical presentation and microscopic findings. In this retrospective study of 86, cases of oral lichen planus (OLP) were compared with 73 cases of oral lichenoid lesions (OLL). Various clinicohistopathological features were studied. The object of this study was to compare clinical and microscopic findings in order to present evidence that supports the position of true lichen planus. Biopsy specimens were obtained from every patient. The biopsy specimens were fixed in 10 percent formalin, embedded in paraffin, sectioned at 4 microns and stained by means of routine hemotoxylin and eosin procedures. The histologic specimens were examined and evaluated without knowledge of clinical findings. The mean age at presentation of patients with OLP was 42.5 years as compared to 47.0 years for OLL. There was no significant difference between the ethnic groups, site of lesions and the distribution of the clinical presentation. Compare to histopathologic findings, there were only 55% clinical and histological agreement in this study, this because of using strict criteria for oral lichen planus there could be an over diagnosis lesions. This study showed that there were no reliable clinical and histopathological features which could differentiate OLL from OLP. The features in the OLL group were non specific. The patient’s medical history, oral habits or psychological status appeared to be able to alter the classical clinicopathological findings.

Introduction: Several factor limits of services of dental composite have triggered further improvement. ZrO2-Al2O3-SiO2 system as filler of dental composite had been developed with sol-gel technique. Ultrasonic homogeniser were reported to change the particle size ditribution or shape. Unifom size and distribution of particle is believed to help define the behavior of hardness properties. Methods: The study was an laboratory experimental design. Filler ZrO2-Al2O3-SiO2 system were developed via sol-gel methods. Post calcination process, filler were immerse in ethanol and applied with ultrasonic homogeniser, with various amplitude i.e 50 rpm, 60 rpm and 80 rpm then named sample A, B, and C. XRD, SEM anda PSA were used to characterize of filler system. Subsequent filler were used to fabricate dental composite then evaluate the hardness value using micro-hardness tester. One–way ANOVA was used to analysis the statistical result of hardness value. Results: XRD pattern of three sample were similar in which tetragonal zirconia was prominent (57-61 %) followed by monoclinic zirconia (24-25%) and amorphous (15-17 %). While, SEM and PSA characterization showed amplitude 50 rpm (sample A) produce more uniform size and well-distributed particle filler than the others. In contrary, sample B and C showed higher peak in PSA results. It means there was dominating of filler with particular size. However, the hardness value did not show significant differences between those filler (p>0,05). Conclusion: Dental composite that contain of different uniformity and distribution of filler ZrO2-Al2O3-SiO2 system has no significantly differences of hardness value.
