Abstract

Background: Enterococcus faecalis (E. faecalis) is the bacteria most commonly resulting from failed root canal treatment. Intracanal medicament is used to enhance the success of root canal treatment. A material widely used for this purpose is calcium hydroxide. However, its ineffectiveness in eliminating E. faecalis requires the addition of other antibacterial substances, such as iodoform which has the disadvantage of having toxic effects on tissues. Pineapple peel has antibacterial properties because it contains chemical compounds, such as flavonoid, saponin, tannin, as well as the enzyme bromelain. Purpose: The aim of the study was to determine the antibacterial activity of a mixture of pineapple peel extract at 6.25% and 12.5% concentrations and calcium hydroxide paste at a ratio of 1:1 compared to100% calcium hydroxide and a mixture of calcium hydroxide and iodoform paste against E. faecalis. Methods: The research was laboratory-based experiment in nature. Sample groups were divided into two control groups (one featuring100% calcium hydroxide paste and a second featuring a mixture of calcium hydroxide and iodoform paste) and two treatment groups (mixture of pineapple peel extract and calcium hydroxide paste in 6.25% and 12.5% concentrations with ratio 1:1). The method was using agar diffusion. The result data were analyzed by One Way Anova test. Results: The highest average of the inhibitory zone occurred in group with a mixture of pineapple peel extract 12.5% and calcium hydroxide paste while the smallest average was that of group with a mixture of calcium hydroxide and iodoform paste. Conclusion: Mixture of pineapple peel extract in 6.25% and 12.5% concentrations and calcium hydroxide paste ratio 1:1 has higher antibacterial activity than paste of 100% calcium hydroxide and mixture of calcium hydroxide and iodoform paste againts E. faecalis.

Abstract

Background: Cigarette smoking is a public health issue that may influence the physical properties of dental composites. Surface roughness is one of the physical properties of restorative materials potentially influencing their success. The use of nanofilled and nanohybrid composites in dentistry has increased substantially over the past few years. Purpose: The purpose of this study was to evaluate the surface roughness of nanofilled and nanohybrid composite resins exposed to kretek cigarette smoke. Methods: Twelve cylindrical specimens of each material were prepared and divided into two groups (n=6). In the control groups, the specimens were immersed in distilled water for 24 hours at 37°C, with the water being renewed daily. For the experimental groups, the specimens were exposed to kretek cigarette smoke on a daily basis, then washed and soaked in distilled water at 37°C. After 21 days, the specimens were measured using a Surface Roughness Tester and the data was then statistically analyzed. Results: An Independent-T Test revealed that there were statistically significant differences in the surface roughness between the control and experimental groups of both nanofilled and nanohybrid composites, as well as between the nanofilled experimental group and the nanohybrid experimental group. Conclusion: Exposure to kretek cigarette smoke can increase the surface roughness of nanohybrid composites to a significantly greater extent than nanofilled composites.

Abstract

Background: Dental digital radiography is more practical and requires fewer doses of radiation than conventional radiography. Because ionizing radiation has a biological effect on exposed tissue, concerns regarding its stochastic effect merit greater attention. In a previous study, it was found that biological changes and increases in the micronucleus occurred after conventional panoramic exposure to gingival crevicular fluid (GCF). Purpose: The purpose of this study is to investigate the difference in biological effects after digital panoramic exposure compared with conventional exposure. Methods: Twenty subjects were classified into two groups according to the radiographic technique employed. The techniques consisted of ten subjects undergoing digital panoramic radiograph exposure and ten others being subjected to conventional exposure. GCF calculated in mm3 was collected by applying paper strips to the anterior maxillary labial gingival sulcus for one minute prior to and ten minutes after exposure. A micronucleus was obtained from a gingival smear on the same quadrant ten days after panoramic exposure. Results: There was a significant difference in the number of micronuclei between conventional and digital panoramic radiographs both before and after exposure (p=0.000). In contrast, increased GCF volume was not statistically significant (p=0.506) before or after digital panoramic exposure, while the significant difference of conventional panoramic exposure was p=0.017. Conclusion: Digital panoramic radiograph exposure induced a biological change only in terms of an increase in the number of micronuclei but not in the volume of GCF.

Abstract

Background: Tooth extraction is the process of removing a tooth from the oral cavity potentially triggering a wound healing response in the body. As a result, many methods have been applied to improve the wound healing process, especially in wounds resulting in complications. One such method involves the application of amniotic membrane which has anti-inflammatory, anti-bacterial, anti-fibrosis, anti-scarring properties with low immunogenicity, epithelialization effects, and secretory leukocyte protease inhibitor (SLPI). It also contains collagen, various growth factors, transferrin, fibronectin, nidogen, proteoglycans, hyaluronan, and laminin. Purpose: This study aimed to determine the effects of sponge amnion on the number of VEGF expressions and new blood vessels in post-tooth extraction wounds of Wistar rats. Methods: Sponge amnion was produced by mixing freeze-dried amnion membrane from the Tissue Bank at RSUD Dr. Soetomo with 1% gelatin before freeze drying the mixture. Wistar rats were then divided into two groups. In Group 1, referred to as the control group, the post-extraction wounds of the rats received no treatment. Meanwhile, in Group 2, the treatment group, the subjects’ post-extraction wounds were treated with sponge amnion. The rats of both groups were sacrificed on day 3 to allow observation of the number of VEGF expressions and new blood vessels. A statistical analysis test, a t-test, was subsequently conducted. Results: There was a significant difference in the number of new blood vessels in the control group and that of the treatment group with a p value of 0.018 (p<0.05). There was also a significant difference in VEGF expression between the two groups with a p value of 0.000 (p <0.05). Conclusion: Sponge amnion can generate a number of VEGF expressions and new blood vessels in the post-extraction wounds of Wistar rats.

Abstract

Background: Peutz-Jeghers syndrome (PJS) is an inherited autosomal dominant disease determined by a mutation localized at 19p13.3 characterized by the occurrence of gastrointestinal hamartomatous polyps in association with mucocutaneous hyperpigmentation. The manifestation of PJS may first be encountered by a dentist during routine examination due to the presence of pigmented spots in the oral cavity. Purpose: To prevent a high risk of PJS, the dentist must establish its oral manifestation through early detection. Case: A 14-year-old male patient attended complaining of a week-long pain at the corners of the lips. An extra-oral exam revealed fissure lesions, redness, white crust and pain. The patient had experienced bleeding in his bowel movements, abdominal pain, nausea and vomiting since childhood. A number of black, painless, macular lesions, some 1-3 mm in diameter, were present on the upper lips, lower lips, fingers and palms. Case management: The patient was referred for a complete blood count check. The results obtained confirmed him to be suffering from severe anemia and he was, therefore, referred to an internist for treatment for PJS. Conclusion: It can be concluded that the early detection of PJS is crucial in order that the patient receives prompt treatment.

Abstract

Background: Streptococcus sanguinis (S. sanguinis), an oral commensal bacterium, is often implicated in infective endocarditis. Its adherence to the tooth surface is the initial step in dental plaque formation. In addition to the important role of S. sanguinis in systemic disease and antimicrobial resistance, it is necessary to develop methods to control dental plaque formation. Immunoglobulin Y (IgY) has been used to prevent bacterial infection. Purpose: The purpose of this study is to analyze the ability of anti-S. sanguinis IgY antibodies to inhibit S. sanguinis adherence to hydroxyapatite (HA) discs as a model of the tooth surface. Methods: Antibodies were produced by immunizing hens with S. sanguinis suspension. Boosters were given three times following the first injection. An agar gel precipitation test (AGPT) was used to detect the presence of anti-S. sanguinis IgY. A bacterial adherence assay was performed twice to analyze the ability of IgY and the optimal concentration required to inhibit bacterial adherence. Results: The formation of a precipitation line using AGPT confirmed the presence of the antibody. In addition, it was shown that the anti-S. sanguinis IgY antibody could inhibit bacterial adherence to HA. Statistical analysis using One-way ANOVA revealed a significant difference in the optical density (OD) value between the groups (p<0.05). The results of electron microscopy scanning confirmed the quantitative analysis by means of a bacterial adherence test. Conclusion: Anti-S. sanguinis IgY has the ability to inhibit adherence of S. sanguinis to HA discs at an optimal concentration of 30%. The inhibitive effect was stronger in the presence of saliva.

Abstract

Background: In Indonesia, dental caries constitute one of the most common dental health problems in children. Untreated dental caries will cause both pain and inconvenience when eating, resulting in a reduced appetite which can negatively affect the Body Mass Index (BMI). Purpose: This study aimed to investigate the correlation between untreated caries and nutritional status in children aged 6-12 years old in the Medan Maimun and Medan Marelan sub-districts. Methods: An analytical observation study with cross-sectional design was adopted. The number of child subjects totaled 350, divided into two groups, namely; the PUFA/pufa group (n=172) and the Non-PUFA/pufa group (n=178). Samples were selected on the basis of purposive sampling. Oral examination was subsequently performed using the PUFA/pufa index. The height and weight of the subjects were assessed according to the Indonesian Ministry of Health’s BMI criteria of 2011. Thereafter, Chi square, Spearman and Mann-Whitney tests were all performed as analytical tests. Results: The results of this research revealed a significant correlation between caries status and BMI (p<0.001) in both the PUFA/pufa and Non PUFA/pufa groups (r=-0.515), as well as between the mean PUFA/pufa score and age. However, there was no significant correlation between the mean PUFA/pufa score and gender. Conclusion: It can be concluded that a correlation exists between untreated caries and the nutritional condition of children aged 6-12 years old in the Medan Maimun and Medan Marelan sub-districts.

Abstract

Background: Oral health surveys conducted on a very large population involve many examiners who must be consistent in scoring different levels of an oral disease. Prior to the oral health survey implementation, a measurement of inter-rater reliability (IRR) is needed to know the level of agreement among examiners or raters. Purpose: This study aimed to assess the IRR using consensus and consistency estimates in large population oral health surveys. Methods: A total of 58 dentists participated as raters. The benchmarker showed the clinical sample for dental caries and community periodontal index (CPI) score, with the raters being trained to carry out a calibration exercise in dental phantom. The consensus estimate was measured by means of a percent agreement and Cohen’s Kappa statistic. The consistency estimate of IRR was measured by Cronbach’s alpha coefficient and intraclass correlation. Results: The percent agreement is 65.50% for photographic slides of dental caries, 73.13% for photographic slides of CPI and 78.78% for calibration of dental caries using phantom. There were statistically significant differences between dental caries calibration using photographic slides and phantom (p<0.000), while the consistency of IRR between multiple raters is strong (Cronbrach’s Alpha: >0.9). Conclusion: A percent agreement across multiple raters is acceptable for the diagnosis of dental caries. Consistency between multiple raters is reliable when diagnosing dental caries and CPI.

Abstract

Background: Diabetes is a serious and important public health problem, especially in relation to dental treatment. Because of its complications in periodontal tissue, diabetes can be contraindicated in patients undergoing orthodontic treatment. The receptor activator of nuclear factor-κb ligand (RANKL) is an essential cytokine inducing osteoclastogenesis. Osteoblasts produce this cytokine which has been suggested to play an integral role in osteoclast activation during bone remodeling of orthodontic tooth movement. Purpose: The aim of this study was to determine the correlation between RANKL expression of osteoblast and the number of osteoclasts in the alveolar bone of diabetic rat models at different mechanical force application. Methods: This study used animal subjects, white rats (Rattus norvegicus) of the Wistar strain (n=24) divided into six groups. The mechanical force to which they were subjected ranged between 10, 20, and 30 gramforce (grf). The animal models with diabetes were injected with a stratified dose of Streptozotocin. An orthodontic appliance was inserted in both the maxillary incisors for seven days. The tissue was subjected to histological analysis of osteoclasts and immunohistochemistry analysis of RANKL expression on the pressure and tension side of the alveolar bone. Results: The results of this study showed that the increase in mechanical force produced a rise in RANKL expression and osteoclast number on the pressure and tension side of the alveolar bone of diabetic rat models. Conclusion: There was a correlation between the RANKL of osteoblast and osteoclast numbers in the alveolar bone of diabetic models with different mechanical force application.
