Abstract

Background: Trauma-induced ulcers constitute one of the painful abnormalities affecting the oral cavity about which numerous individuals complain. The prevalence of traumatic ulcers (15-30% of cases) is relatively high compared to other oral lesions. Unfortunately, the use of anti-inflammatory drugs classified as steroids can lead to contraindications and serious side effects. Hence, the use of natural ingredients represents an alternative treatment. One such ingredient is red pomegranate containing bioactive elements acting as anti-inflammatory, antibacterial, antimicrobial, and antioxidant agents which accelerate the healing process in traumatic ulcers. Purpose: The aim of this study was to determine the effects of the topical application of red pomegranate (Punica granatum Linn) extract on the healing process in traumatic ulcers in Wistar rats. Methods: 24 male rats, aged 2-3 months, were divided into six groups, namely; two control groups (PC: triamcinolone acetonide and NC: sterile aquades) and four treatment groups (red pomegranate extract gel at respective concentrations of 12.5%, 25%, 50% and 75%). A traumatic ulcer was subsequently created using a flame-shaped burnisher tip 2mm in diameter and heated for ±15 seconds. The diameter traumatic ulcer of each research subject was measured and observed until it healed within the remedial parameters determined by means of a UNC-15 periodontal probe which had been placed on it. The data obtained was analyzed using Kruskal-Wallis and Mann-Whitney tests. Results: Topically applied red pomegranate extract gel can reduce the width of the ulcerated area, while also accelerating traumatic ulcer healing. There was a significant difference in the healing time between the group using red pomegranate extract gel at a concentration of 75% and the positive control group using 0.1% triamcinolone acetonide with p=0.44 (p<0.05). Conclusion: Red pomegranate extract gel possesses the ability to accelerate the healing process in traumatic ulcers. The most effective concentration of red pomegranate extract gel at accelerating the healing process in traumatic ulcers is 75%.

Abstract

Background: Oral health has been promoted in elementary school. Oral health status is worsening among children aged 12 in Indonesia. Schools are an ideal social environment where dental health promotion strategies could be implemented to improve children’s oral health and to develop lasting good oral health behavior. Purpose: This study aimed to determine the association of sex, age, oral health behavior (tooth brushing practice, eating sweets and snacks, and routine dental health care visit) and family support, with oral health status among elementary school-children. Method: A school-based survey was carried out in 45 public elementary schools served by15 community health centers in Sleman, Yogyakarta. All fifth grade students (a total of 1191 students) in the schools were recruited as study participants after informed consent being given to parents. Questionnaires on health behavior and family support were administered to students, and examinations for OHIS and DMF-T were conducted by trained research assistants. Regression analyses (with R) were performed to identify whether sex, age, oral health behavior, family support and schools were significant determinants of oral health. Result: Females had higher DMF-T compared to males (1.93 vs 1.56), older children showed higher DMF-T. Effects oral health behavior and family support on OHIS and DMF-T were not significant after adjusting for school. School was significantly associated with OHIS and DMF-T. Conclusion: Sex and age were determinants of DMF-T. Oral health behavior and family support were not associated with OHIS and DMF-T. School was a consistent predictor of OHIS and DMF-T. School-based programs, especially targeted to certain schools with worse oral health, should be strengthened.

Abstract

Background: Periodontal disease is a progressive destructive change that causes loss of bone and periodontal ligaments around the teeth that can eventually lead to its loss. The main bacteria in chronic periodontitis is Porphyromonas gingivalis. Aggregatibacter actinomycetemcomitans, a pathogen associated with aggressive periodontitis, initiates a proinflammatory response that causes tissue destruction of periodontal, alveolar bone resorption and subsequent tooth loss. Electrolyzed reduced water (ERW) is an alkaline water, ERW not only has a high pH and low oxidation reduction potential (ORP), but also contains several magnesium ions. Magnesium ions proven effective for the prevention of various diseases. Purpose: To analyze the level of malondialdehyde (MDA) in Wistar rats with cases of chronic and aggressive periodontitis that consumed ERW. Method: Wistar rats were divided into four groups, each group with 10 rats. The first and second group were Wistar rat with chronic periodontitis and consume drinking water and ERW. The third and fourth group were Wistar rat with aggressive periodontitis and consume drinking water and ERW. This experiment is done by calculating the levels of MDA. The calculation of the levels of MDA is done with spectrophotometric assay for MDA. Result: The results of this experiment show that the level of MDA in serum in group that consume ERW had decreased significantly different with thegroup that consume drinking water with the statistical test. Conclusion: It can be concluded that ERW can decrease the MDA level in Wistar rat with chronic and aggressive periodontitis case.

Abstract

Background: Tooth eruption, the movement of teeth toward the oral cavity clinically marked by the emergence of the cusp or incisal edge, is very important in determining the chronological age of a child. Unfortunately, tooth eruption in 6-12-year olds on the island of Madura has yet to be investigated. Purpose: This study aimed to analyze differences in permanent tooth eruption between boys and girls aged 6 to 12 years old on Madura. Methods: This study employed an observational analytic design in combination with a cross-sectional approach. The samples used in this study were selected by means of simple random sampling technique. Post-selection informed consent of the child subjects was obtained with their chronological age being assessed and determined prior to tooth eruption. The normality of the data was subsequently analyzed by application of a one sample non-parametric Kolmogorov Smirnov test. Thereafter, repeated Anova tests were conducted to determine differences in the permanent tooth eruption of the subjects. Results: Based on the normality test results, the significance value of the permanent maxillary teeth in the male subjects was 0.993, while that of their permanent mandibular teeth was 0.695. In contrast, the significance value of the permanent maxillary teeth in the female subjects was 0.970, while that of their permanent mandibular teeth was 0.918. According to the results of the repeated measure ANOVA test, differences existed in the eruption of the permanent maxillary and mandibular teeth between the males and females with a significance value (ρ) of 0.020. The mean value of permanent mandibular tooth eruption in the females was 56.59 ± SD 33.403, while that of their permanent maxillary tooth eruption was 50.77 ± SD 34.201. The mean value of the permanent mandibular tooth eruption in the males was 55.31 ± 33.024, while that of their permanent maxillary tooth eruption was 48.77 ± SD 34.201. Conclusion: On Madura, the permanent teeth of chronological 6-12-year old females, particularly their permanent mandibular canine teeth, erupt earlier than those of their male counterparts.

Abstract

Background: Fixed orthodontic appliances with ceramic brackets are used frequently to fulfill the aesthetic demand of patient through orthodontic treatment. Ceramic brackets have some weaknesses such as bond strength and enamel surface damage. In high bond strength the risk of damage in enamel surfaces increases after debonding. Purpose: This study aimed to determine the effect of silane on base of bracket and adhesive to shear bond strength and enamel structure of ceramic bracket. Method: Sixteen extracted upper premolars were randomly divided into four groups based on silane or no silane on the bracket base and on the adhesive surface. Design of the base on ceramic bracket in this research was microcrystalline to manage the influence of mechanical interlocking. Samples were tested in shear mode on a universal testing machine after attachment. Following it, adhesive remnant index (ARI) scores were used to assess bond failure site. Statistical analysis was performed using a two-way Anova and the Mann-Whitney test. A scanning electron microscope (SEM) with a magnification of 2000x was used to observe enamel structure after debonding. Result: Shear bond strength was increased between group without silane and group with silane on the base of bracket (p<0,05). There was no significance different between group without silane and group with silane on adhesive (p<0,05). Conclusion: Application of silane on base of bracket increases shear bond strength, however, application of silane on adhesive site does not increase shear bond strength of ceramic bracket. Most bonding failure occurred at the enamel adhesive interface and damage occurred on enamel structure in group contains silane of ceramic bracket.

Abstract

Background: Tooth extraction is the ultimate treatment option for defective teeth followed by the need for dentures. Inflammation is one phase of the healing process that should be minimized in order to preserve alveolar bone for denture support. Macrophage, PMN and lymphocyte cells are indicators of acute inflammation. Spirulina and chitosan are natural compounds with the potential to be anti-inflammatory agents. Purpose: This research aimed to determine macrophage, PMN and lymphocyte cells of animal models treated with a combination of 12% spirulina and 20% chitosan on the 1st, 2nd and 3rd post-extraction day. Methods: Animal models were randomly divided into control (K) and treatment (P) groups. Each group was further divided into three subgroups (KI, KII, KIII and PI, PII, PIII). The post-extraction sockets of the control group animals were then filled with CMC Na 3%. Meanwhile, the post-extraction sockets of the treatment group members were filled with a combination of 12% spirulina and 20% chitosan. Subsequently, the number of PMN, macrophage and lymphocyte cells was analyzed by means of HE analysis on the 1st., 2nd. and 3rd. days. Statistical analysis was then performed using a T-test. Results: There was a decrease in PMN cells and an increase in macrophage and lymphocyte cells on Days 1, 2, and 3. Conclusion: It can be concluded that a combination of 12% spirulina and 20% chitosan can not only decrease PMN cells, but can also increase macrophage and lymphocyte cells on Days 1, 2 and 3 after tooth extraction.

Abstract

Background: Enterococcus faecalis (E. faecalis) is a bacterium commonly detected in the root canals of teeth with post-treatment apical periodontitis or advanced marginal periodontitis. It has the ability to live in an extreme environment and survive as an organism with its virulence factor possibly contributing to the pathogenesis of post-treatment apical and marginal periodontitis. Photodynamic therapy (PDT) is an urgently required alternative method of improving therapy effectiveness. Photodynamic therapy combined with conventional endodontic treatment decreases the number of antibioticresistant bacteria and biofilms. Chlorophyll is one of the photosensitizers added to enhance the absorption of light in photodynamic therapy. Purpose: The purpose of this study was to determine the antimicrobial effect of the combination of photodynamic laser therapy and Alfalfa chlorophyll in E. faecalis. Methods: In vitro study using E. faecalis distributed between negative control (C-) and positive control (C+), treatment groups using various energy doses of a 405 nm diode laser (2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20 J/cm2) with (G1) and without alfalfa chlorophyll as organic photosensitizer (G2). The suspension was inoculated on Tryptocase Soy Agar (TSA) and incubated at 37° C for 24 hours. The number of colonyforming units per milliliter (CFU/ml) was determined. The results were analyzed by ANOVA with p value ≤0.05. Results: A 405 nm irradiating laser with or without a photosensitizer can decrease E. faecalis viability percentage through the administering of various energy doses. The highest decrease (42%) was obtained in the group without a photosensitizer using 20 J/cm2, while 10 J/cm2 in the group with a photosensitizer proved the most effective dose (25%). Conclusion: The results of this study showed a decrease in the viability of E. faecalis exposed to a 405 nm (40 mW) laser. An irradiating process using a 405 nm laser without a photosensitizer (Alfalfa chlorophyll) resulted in the highest percentage decrease (42%) in E. faecalis bacterial viability.

Abstract

Background: Odontectomy of lower third molar has a potential risk for inferior alveolar nerve impairment. Paresthesia of inferior alveolar nerve has often been associated with close relationship between the apex of lower third molar and mandibular canal. Rood and Shehab’s category has been commonly used for radiological prediction of inferior alveolar nerve injury following third molar surgery. Purpose: This study aimed to determine whether there was correlation between Rood and Shehab’s radiographic features and the incidence of inferior alveolar nerve paraesthesia following odontectomy of lower third molar. Method: This was a retrospective cross-sectional study, using data obtained from the dental record of patients who had undergone odontectomy of lower third molars in Dental hospital of Universitas Airlangga during 2 years period. Samples were cases that, from presurgical radiograph, showed close relationship between lower third molar roots and mandibular canal. The case and non-case groups were assigned based on the presence of paraesthesia and non-paraesthesia of inferior alveolar nerves, respectively. Based on Rood and Shehab’s category, the samples collected were then classified into two groups which were those whose relationship matched and did not match with the category, respectively. Data were analyzed using Chi-square correlation test. Result: Of 975 odontectomy cases included in this study, 80 cases were taken as study samples consisting of 15 and 65 cases assigned, respectively, as case and non-case. The 32 cases matched with the criteria of Rood and Shehab's category while the remainder of 48 cases did not. Of 32 cases which met the criteria of Rood and Shehab’s relationship, only 5 cases showed paraesthesia, whereas out of 48 cases which did not met the criteria 10 cases showed paraesthesia. Statistical analysis showed significance value of 0.770 (p>0.05) indicating that there was no significant correlation between relations of third molar root and mandibular canal, based on Rood and Shehab’s category, and the incidence of inferior alveolar nerve paraesthesia. Conclusion: There was no correlation between Rood and Shehab’s radiographic features and the incidence of paraesthesia of inferior alveolar nerve following odontectomy of lower third molars.

Abstract

Background: Dental caries is a major problem in oral cavity. If dental caries causes cavity, the structure of dental hard tissue will not be reversible because of damage in the structure of the hard tissue. The early pathogenesis mechanism of dental caries is an adhesion interaction between cariogenic Streptococcus mutans microorganisms and tooth surface pellicles. The attachment involves a specific molecular component interaction between the bacterial complement molecules and the surface of the host. Streptococcus sanguis as a dominant ecology at the beginning of bacterial plaque aggregation will colonize the tooth surface earlier than S. mutans. The surface of bacterial cells can express some adesin. The bacteria also can express receptors for adhesins of other bacteria. Specific receptors for adhesions of S. Mutans bacteria are not only found in the pellicles, but also present in pioneer bacteria, such as S. sanguis. Adhesion between those bacteria is called as coagregation. Purpose: This study aimed to analyze the characterization of Streptococcus sanguis molecular receptors for Streptococcus mutans binding molecules. Method: This study used a sonication method for protein isolation of S. mutans and S. sanguis bacterial biofilms, as well as electrophoresis method using 12 % SDS-PAGE gel and Western Blot analysis. Result: Results of the protein profile analysis of S. mutans biofilms using 12% SDS-PAGE showed that there were 17 bands, each of which molecular weights was 212, 140, 81, 65, 61, 48, 45, 44, 40, 39, 33 , 25, 23, 19, 17, 12, and 11 kDa. On the other hand, results of the protein profile analysis of S. sanguis biofilms using 12% SDS-PAGE showed that there were 15 bands, each of which molecular weight was 130, 85, 65, 61, 48, 46, 40, 37, 29, 25, 23, 21, 17, 15, and 12 kDa. And, results of the analysis of S. sanguis receptor molecules using Western blot showed that there were three bands, each of which molecular weight was 130, 85, and 40 kDa. Conclusion: S. sanguis bacteria have specific receptor molecules for S. mutans bacteria with the molecular weight of 130, 85, and 40 kDa.
