Health Research in 2013 showed that 24.8% of children with health problems and dental caries index reached 1.4. A’yun’s Predictor Software (APS) was a new tool to describe the interaction of various factors that play a role in the caries process. The program was developed to establish a better understanding of the multi-factorial aspects of dental caries in children,as well as a guide to improve behavior to reduce the risk of new caries. This study in children aged 10-12 years in SDN Baturan I,SDN Baturan II,SDN Mayangan and SD Muhammmadiyah Trini in Sleman,Yogyakarta.Sampling technique was simple random sampling. This type of research was quasi-experimental control group(pretest and posttest design with control group). The independent variable was oral health education with APS and the dependent variable was the behavior of dental health maintenance oral and mouth, salivary pH and PHPM (Personal Hygiene Performance-Modified)index.Results data were analyzed by t-test. Research shown that there were significant differences between the treatment group and control group on the behavior of the maintenance of oral health of children and PHPM index (p <0.05), while the pH of saliva there was not to be difference (p> 0.05). The conclusions of this study was significant APS application on dental health maintenance behavior oral and mouth, salivary pH, and the index PHPM in school children.

Osteoporosis is a bone disease characterized by reduced bone mass and damage to the microarchitecture of bone tissue. One of osteoporosis types is primary type-1 osteoporosis or postmenopausal osteoporosis due to estrogen deficiency. Calcium is an important mineral that plays a central role in the formation of bone strength structure. Jackfruit seeds (Artocarpus heterophyllus) contain isoflavones that can replace the role of estrogen in the body. Fortification of jackfruit seeds and high calcium milk can be a potential alternative for the treatment of postmenopausal osteoporosis. The purpose of this study was to determine the effect of drinking high calcium milk fortified with jackfruit seed extract (Artocarpus heterophyllus) on alveolar bone collagen fiber density of menopause induced rats. Twenty-five Sprague dawley rats were included in this study. Twenty Sprague dawley rats were ovariectomized, while 5 rats were left untreated (normal control group). Seven days after ovariectomy was performed, 5 rats were treated with fortification of jackfruit seed extract and high calcium milk, 5 rats were treated with jackfruit seed extract, 5 rats were treated with high calcium milk, and 5 rats were left untreated (ovariectomized control group). The treatments were done for 28 days. The rats were euthanized and the alveolar bone was taken and processed for a histological specimen. Alveolar bone collagen fibers were observed under a binocular microscope with 100 magnification. Kruskal-Wallis result showed there was a significant difference in the alveolar bone collagen fiber density among these groups (p<0.05). Mann-Whitney U Test showed a significant difference (p<0.05) in the alveolar bone collagen fiber density of the rats treated with fortification of jackfruit seed extract and high calcium milk compared to the group treated with jackfruit seed extract, that with high calcium milk, or ovariectomized control group. No significant difference in alveolar bone collagen fiber density was found between the group treated with fortification of jackfruit seed extract and high calcium milk and the normal control group (p>0.05). In conclusion, consuming high calcium milk fortified with jackfruit seed extract increases the density of alveolar bone collagen fibers.

Oral mucositis is an inflammatory process and ulcerative of the oral mucosa due to chemotherapy and/or radiotherapy. The incidence and severity of oral mucositis might be influenced by a variety of risk factors, related to the host and treatment of the cancer. This aim of the case report is to evaluate risk factors that affect the severity of oral mucositis in two patients with nasopharyngeal cancer undergoing chemotherapy and/or radiotherapy. The first case, oral mucositis grade III and oral candidiasis to a 54-year old woman undergoing 16 times radiotherapy for nasopharyngeal cancer stage IV. The second case, oral mucositis grade I and oral candidiasis were found in a 55-year old man suffering from nasopharyngeal cancer stage IV who has been treated 10 times with chemotherapy and radiotherapy. Both patients had a similar age range and cancer stage. The differences of severity oral mucositis in both cases were suspected due to the host factors-related that are gender and nutritional status. In addition, intra-oral condition (poor oral hygiene, xerostomia), smoking habits and patient compliance may also affect the severity of oral mucositis in the second case. Treatment factors such as the type, dose and duration of chemotherapy t, might also affect the severity in both cases. Both patients were given chlorhexidine gluconate 0.2%, nystatin oral suspension, vitamin B12, and folic acid for treating oral mucositis. In conclusion, the understanding of risk factors oral mucositis is deemed necessary to control the severity and to provide an appropriate management to improve the quality of patients’ life.

Demineralization is a process of partial or full tooth mineral loss which caused by acidic environment, for example the side effect of extracoronal bleaching treatment. Demineralization increases enamel surface roughness which leads plaque accumulation. Whey extract and calcium phosphopeptide-amorphous calcium phophate (CPP-ACP) contain calcium and phosphate that can stop the demineralization through remineralization process. This study aimed to determine the differences of enamel surface roughness after whey extract and CPP-ACP application post- extracoronal bleaching. Experimental laboratory with pre- and post-test control group design was performed on 24 first maxillary premolars which devided into 3 groups. On group I, specimens were immersed in artificial saliva. Specimens in group II were immersed in whey extract meanwhile specimens were immersed in CPP-ACP on group III. Whey extract and CPP-ACP immersions were conducted 10 minutes every 12 hours for 15 days. The enamel surface roughness test was performed twice, after extracoronal bleaching treatment and after 15 days remineralization agent application. This study result indicated significant differences between group I and group II and between group I and group III (p<0.05), but there was no significant difference between group II and group III (p>0.05). This study showed whey extract decreased more enamel surface roughness than CPP-ACP but the difference was not significant statistically. So, whey extract and CPP-ACP showed similar remineralization potential.

The availability of dental E-glass fibers for Fiber Reinforcement (FRC) restoration is limited in Indonesia with relatively high cost.Therefore, non-dental glass fibers have been used as an alternative material. The composition of non-dental glass fibers is almost the same with dental E-glass fibers. An important parameter responsible for the strength of FRC is the impregnation of the fibers with resin. Reinforcing fibers are difficult to impregnate with the resin systems of high viscosity. The aim of study is to assess the effect of non-dental glass fibers impregnation using bis-GMA and TEGDMA resin on the flexural strength of FRC. The materials used in the study were non-dental glass fibers (CMAX, China), resin bis-GMA (Sigma-Aldrich, USA) and TEGDMA (Sigma-Aldrich, USA). Three groups of samples consisted of FRC with non-impregnated fibers, FRC with impregnated fibers (bis-GMA:TEGDMA=4:1) and FRC with impregnated fibers (bis-GMA:TEGDMA=1:1). The three groups were tested to determine flexural strength according to ISO 10477. The samples were stored in aquadest at 37 °C for 24 hours prior to flexural strength test. The results were analyzed by one way ANOVA with LSD post hoc test. The results of study showed that the lowest mean of flexural strength (116.16 ± 15.87MPa) was FRC with non-impregnated fiber and the highest mean (151.32 ± 23.74 MPa) was FRC with impregnated fiber (bis-GMA:TEGDMA=1:1). The statistical analysis showed that fiber impregnation had a significant effect (p< 0.05). It can thenbe concluded that non-dental glass fiber impregnation using bis-GMA and TEGDMA resin could increase the flexural strength of FRC and FRC with the impregnated fibers (bis-GMA:TEGDMA=1:1) that had the highest mean of flexural strength.

The demineralization of dental hard tissues can be caused by dental plaque. Dental plaque contains various components, especially bacteria attached to the extracellular matrix. Streptococcus mutans (S. mutans) has extracellular glucan as adhesin that is important in the attachment mechanism of tooth surface. The natural substance can be used for preventing plaque formation by inhibiting the attachment of S. mutans. Soursop plant has been used in treating various diseases. The leaves of the soursop (Annona muricata L.) are used as a material to inhibit potential attachment of bacteria S. mutans. Common surfaces that is used in adhesion testing is hydroxyapatite (HA). The aim of this study was to evaluate the effect of ethanol extract of soursop leaf (EESL) on the adhesion of S. mutans ATCC 35668 to HA discs. Soursop leaves were extracted by the maceration method using 70% ethanol. The experiment was carried out by analyzing the inhibition adhesion of S. mutans ATCC 35668 on HA discs after incubation with different concentrations of soursop leaf extract. The concentrations of extract tested were: 150; 125; 100; 75; and 50 mg/ml. Chlorhexidine 0.2% was used as a positive control while DMSO 5% was used a negative one. Data were evaluated by One Way Anova. This study statistically showed significant differences of S. mutans colony count between groups (p<0.05).The results of a post hoc Dunnett T3 test showed that the 2 highest concentrations of extract (125 and 150 mg/ml) reduced S. mutans adhesion on HA discs.The obtained results showed that ethanol extract of soursop leave inhibits the adherence of S. mutans to the HA disc.

Oral cancer is a malignant neoplasia on the lip and oral cavity. It is generally late-detected, locally invasive, and it has a high propensity for cervical lymph node metastases as well as blood-borne distant metastases. Diagnostic imaging for oral cancer is generally performed using conventional radiography, Cone Beam Computed Tomography (CBCT), Computed Tomography (CT), ultrasonography (USG), Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Single-Photon Emission Computed Tomography (SPECT), and bone scintigraphy. This review provides a general overview of oral cancer imaging and basic principles of interpretation for oral cancer using several imaging modalities. The selection of imaging modalities for oral cancer must be based upon clinical condition, availability of imaging modalities, and cost effectivity. Despite the limited availability of modern imaging modalities in Indonesia, understanding on the major concept of various oral cancer imaging and its interpretation are certainly required by the dentists. Imaging and its interpretation are required to assist the diagnosis and determine the most appropriate treatment plan. Thus, the survival rate can be improved.

Diabetes mellitus (DM) is a metabolic disorder characterized by hyperglycemia and become the third cause of death in Indonesia. The most common oral complications occured in DM is periodontitis. Porphyromonas gingivalis (Pg) is the main etiology of periodontitis, one of periodonthopathogen relate to systemic disease. However this theory still controversial, DM and periodontitis have the same pathogenesis, thus are cellular changes. Pg is predicted affect the total leukocytes count in DM. The aim of this study was to determine the effect of Pg infection to total leukocytes count in DM rat model. The rat model of DM was obtained by injection of streptozotocin with different dosage for 5 days sequentially then injected by Pg on distobuccal and distopalatal sulcus of the maxillary first molars for 19 days with interval 3 days. The total leukocytes were calculated manually by Neubauer improved cell counting chamber. The results demonstrated that rat model of DM which injected by Pg has the lowest total leukocytes count. Therefore, Pg infection decreased the total leukocytesin DM rat model.

The aim of this study was to determine the effect of Pg infection to total leukocytes count in DM rat model. The rat model of DM was obtained by injection of streptozotocin with different dosage for 5 days sequentially then injected by Pg on distobuccal and distopalatal sulcus of the maxillary first molars for 19 days with interval 3 days. The total leukocytes were calculated manually by Neubauer improved cell counting chamber. The results demonstrated that rat model of DM which injected by Pg has the lowest total leukocytes count. Therefore, Pg infection decreased the total leukocytesin DM rat model.","PeriodicalId":31262,"journal":{"name":"Majalah Kedokteran Gigi Indonesia","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76695053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bleaching or teeth whitening is a popular dental conservative treatment to enhance aesthetics. Bleaching treatment in many cases has successfully improved aesthetics but still remains the side effects. It can cause some changes in enamel structure leading to demineralization characterized by the emergence of microporosity on the enamel surface. Nano-hydroxyapatite is potential to re-mineralize earlyenamel lesions. This study aims to identify the effect of nano-hydroxyapatite on enamel microporosity after bleaching treatment. Twelve rabbits were randomly divided into two groups. The control and treatment group administered a placebo and nano-hydroxyapatite paste respectively, for 7 days after bleaching treatment. Once the treatment was completed, the rabbit was sacrificed, the jaw was decapitated, upper and lower incisors of the rabbit were separated from the jaw. Subsequently, the sample preparation wasconducted for examination of enamel microporosity depth by using scanning electron microscope. The results showed the control group had more microporositycompared to the treatment group. The independent t-test result showed that enamel microporosityhad a significant value of 0.003 (p <0.05) meaning that enamel microporosity between both groups had a significant difference. The conclusion of this study was administration of nan-hydroxyapatite paste reduced enamel microporosityin the administration of nano-hydroxyapatite pastes compared to the placebo pastes after bleaching treatment.

Cone-beam computed tomography (CBCT) is an imaging modality widely used in dentistry over multi detector computed tomography (MDCT). It is in view of its high resolution with relatively lower dose. MDCT is able to show Hounsfield Unit (HU) which is proportional to x-ray attenuation degree by the tissue. The x-ray attenuation degree in CBCT is shown in grayscale value with pixel values unit. The aim of this study was to determine the correlation of pixel values in CBCT with HU in MDCT. We used secondary data from RSGM Universitas Padjajaran patient who had CBCT and MDCT. Measurement was done on the cortical areas (lingual, buccal, and posterior side) of the mandible and teeth 47 (email, dentin, and pulp) with 5 regions of interest (ROIs) on each area. DICOM software was used for the measurement on CBCT and MDCT data. The result indicated a strong correlation between pixel value in CBCT and HU in MDCT on the cortical bone and teeth area (R=0.846). Linear regression resulted in an equation to derive HU value from pixel value of cortical bone and teeth area, which is y = 1,9011x + 177,15. The conclusion is HU can be derived from CBCT by converting with regression equation.
锥形束计算机断层扫描(CBCT)是一种比多探测器计算机断层扫描(MDCT)更广泛应用于牙科的成像方式。这是由于它的分辨率高，而剂量相对较低。多层螺旋ct显示的Hounsfield Unit (HU)与组织对x射线的衰减程度成正比。CBCT中x射线衰减程度以像素值为单位的灰度值表示。本研究的目的是确定CBCT中像素值与MDCT中HU的相关性。我们使用来自Padjajaran大学RSGM患者的辅助数据，该患者有CBCT和MDCT。测量下颌骨皮质区(舌侧、颊侧和后侧)和牙齿47(电子、牙本质和牙髓)，每个区域有5个感兴趣区域(roi)。采用DICOM软件对CBCT和MDCT数据进行测量。结果显示CBCT像素值与MDCT骨牙皮质区HU值有较强相关性(R=0.846)。线性回归得到由皮质骨牙面积像素值求出HU值的方程为y = 1,9011x + 177,15。结论是将CBCT与回归方程进行转换，可以得到HU。
