Abstract

Background: The adhesion of root canal filling material to dentin is one of the crucial factors in determining the success of endodontic treatment. However, the smear layer that forms during instrumentation serves as an interface that impedes the bonding mechanism of the filling material. A proper irrigation solution is required to remove the smear layer and provide a dentin surface that supports the bonding mechanism of the filling material in establishing good adhesion. Purpose: This study aims to evaluate and compare the bond strength of filling material with different final irrigation solutions. Methods: Mandibular premolars were prepared by a crown down, pressure-less technique and divided into three final irrigation groups (2.5% NaOCl, 17% EDTA and 20% citric acid). The root canal of each tooth was obturated using epoxy sealer and gutta-percha. A two-millimetre-thick section of the apical third portion of each group was arranged for the push-out assessment using a universal testing machine in an apical to coronal direction at 1 mm/min crosshead speed. Results: A one-way ANOVA test indicated the difference in push-out bond strength among the groups (p<0.05). A post hoc Bonferroni test presented a statistically significant difference in the bond-strength value between the 2.5% NaOCl group compared with the 20% CA group (p<0.05). Conclusion: The push-out bond strength of root canal filling material is increased by applying a chelating agent as the final irrigation solution where 20% of CA presents the highest push-out bond strength.

Abstract

Background: Cast analysis is the measurement of the upper and lower arch in a 3-dimensional occlusal relationship. Howe’s Analysis can be used to observe total tooth material, arch length, and basal arch width. Howe’s Analysis was conducted to analyse abnormalities of both teeth and the jaw to help diagnose and plan dental care. Purpose: To analyse the difference in total tooth material, arch length, basal arch width, and Howe’s Index between male and female undergraduate students from the University of Sumatera Utara who are of Proto-Malay origin. Methods: Ninety-six samples comprised of 48 male and 48 female students were recruited through the purposive sampling method. All samples were undergraduate students at the University of Sumatera Utara and of Proto-Malay origin, aged between 18 to 26, and have met the exclusion and inclusion criteria. We measured the variables using a digital caliper to measure basal arch width and arch length and Moorrees’ method to measure total tooth material. Data were analysed statistically using an independent t-test to compare means between groups (p<0.05). Results: The male samples’ average value of total tooth material 98.49 mm±3.79, arch length 45.55 mm±2.28, basal arch width 41.07 mm±2.83, and Howe’s Index were 41.71 %±2.63, respectively. The female samples had a lower value compared to the male samples, 94.51 mm, 43.27 mm, 36.89 mm, and 39.05 % respectively. There was a significant difference in the total tooth material, arch length, basal arch width, and Howe’s Index between male and female undergraduate students from the University of Sumatera Utara of Proto-Malay origin (p=0.001; p<0.05). Conclusion: The average measurement of total tooth material, arch length, basal arch width, and Howe’s Index was higher in male than female undergraduate students from the University of Sumatera Utara of Proto-Malay origin.

Abstract

Background: Periodontitis is an inflammatory disease that occurs in periodontal tissues. Porphyromonas gingivalis is also known as a bacterium commonly associated with the pathogenesis of periodontitis. Tetracycline is one of the antibiotics often used in periodontal tissue treatment. Propolis and Moringa oleifera are also known to have certain compounds assumed to be able to inhibit biofilm growth. Purpose: This study aims to understand the effectiveness of the combination of Moringa oleifera and propolis on porphyomonas gingivalis biofilms compared to 0.7% tetracycline. Methods: A biofilm inhibition activity test was performed using the broth micro dilution method. First, bacteria were prepared by making a suspension in brain heart infusion media and adjusting it to 0.5 McFarland I standard. Second, fifteen samples were divided into five groups; group K as control group (0.1% sodium carboxymethyl cellulose), T (0.7% tetracycline), and treatment groups with the combination of propolis and Moringa oleifera in various concentrations, such as P1(10%+20%), P2(10%+40%), and P3(10%+80%). Third, the result data obtained in the form of optical density (OD) was read by using an ELISA reader. Next, statistical analysis using analysis of the variance test was conducted (p<0.05. Results: There was no significant difference between group T and group P1 (0.075). Nevertheless, there were significant differences between group T and group P2 as well as between group T and group P3 (0.00) (p=< 0.05). Conclusion: The combination of 10% propolis and 40% Moringa oleifera as well as the combination of 10% propolis and 80% Moringa oleifera have better antibacterial effectiveness against Porphyromonas gingivalis biofilm than 0.7% tetracycline.

Abstract

Background: Generally, after tooth extraction, trauma is caused by bone damage, which leads to a decreased bone density. Bone damage repair should be conducted using a bone graft containing hydroxyapatite (HA). HA can be synthesised from gypsum puger powder, which is abundant and easy to obtain. Hydroxyapatite gypsum puger (HAGP) was successful with 100% hydroxyapatite purity level. Purpose: To compare the ratio of trabecular bone density in Wistar rats between HAGP scaffold application and bovine hydroxyapatite (BHA) scaffold application. Methods: This study is a laboratory experiment using 6 treatment groups, namely K (-) polyethylene glycol (PEG) 7, K (-) PEG 28, HAGP + PEG 7, HAGP + PEG 28, BHA + PEG 7, and BHA + PEG 28. HAGP scaffold freeze-drying. The rats were anaesthetised intramuscularly, and their left mandibular incisor was removed. The scaffold was applied to the mouse socket, followed by tissue decapitation after 7 and 28 days. The examination was carried out with micro-computed tomography (Micro-CT). Next, statistical analysis using a one-way analysis of variance (ANOVA) test was conducted (p <0.05). Results: The ANOVA test result showed a difference in bone density between the treatment and control groups on days 7 and 28. The Least Significant Difference (LSD) test result revealed that there was no significant difference between K (-) PEG 28 and HAGP + PEG 7 (p=0.133). Nevertheless, there were significant differences between the other groups. Conclusion: Based on the Micro-CT analysis, the trabecular bone density in Wistar rats following HAGP scaffold application is higher than that of BHA scaffold application.

Abstract

Background: Streptococcus mutans (S. mutans) bacteria mainly cause dental caries in children. These bacteria are not considered oral indigenous bacteria since they are transmitted from people around children during their deciduous teeth eruption. The detection of these bacteria can be used for dental caries prevention in children. Purpose: To determine the strain and serotype of S. mutans by using matrix assisted laser desorption ionization – time of flight mass spectrometry (MALDI-TOF MS) and polymerase chain reaction (PCR) on dental plaque samples taken from mother-child pairs. Methods: Sixteen dental plaque samples of mother-child pairs were cultured on brain heart infusion broth (BHIB) and mitis salivarius bacitracin (MSB) media until S. mutans colony isolates were obtained. Next, the isolates of S. mutans colony were introduced into the target plates of MALDI-TOF MS, and then ionized to become peptide mass fingerprint (PMF). Afterwards, the colony isolates were detected by database software. The detected S. mutans DNA then was extracted by using conventional 727 bp PCR (serotype C). Results: Six strains of S. mutans were detected by MALDI-TOF MS method. Five samples were classified into UA159, two samples were 3SN1, two samples were NFSM1, two samples were 11A1, two samples were U138, two samples were 4SM1, and one sample was classified into another bacterium. Five out of 16 samples were detected by PCR as serotype C (UA159). Conclusion: Six strains of S. mutans were detected, namely UA159, 3SN1, NFSM1, 11A1, U138, and 4SM1, one of them (UA159) was detected as serotype C.

Abstract

Background: Health education games can be an effective way for elementary school children to increase their dental health knowledge and oral health. Purpose: This study aims to test the effectiveness of using reminder sticker books by showing the increase in dental health knowledge and improvement in the Simplified Oral Hygiene Index (OHI-S) in seven- to eight-year-olds. Methods: The study was quasi-experimental with a pretest-posttest group design and descriptive analysis method. It involved 54 elementary school students. A reminder sticker book was used to measure the levels of knowledge and oral hygiene. Intraoral examinations were conducted, and the children’s frequency of attaching stickers in the morning and afternoon was measured. Frequency was divided into three categories. A questionnaire measured the children’s levels of knowledge, which were divided into five categories. Results: The reminder sticker game increased dental health knowledge, with the mean of the control group at 64.4, and the treatment group at 92.5. OHI-S means were 1.68 for the control group and 0.78 for the treatment group. An independent t-test measured the levels of knowledge before and after the study. OHI-S and ANOVA tests measured the increase of dental health knowledge, which was divided into five categories, and decrease in the OHI-S index (divided into three categories). Conclusion: Reminder sticker books can increase oral health knowledge and reduce OHI-S scores in seven- to eight-year-old children.

Abstract

Background: Dental and oral health problems among elementary students can be resolved through an oral health programme in schools. The main factor that inhibited this scheme was that the recording and reporting still employed a manual system, making it less effective and efficient. The electronic application of this programme can help managers to complete both of these tasks. Purpose: This study’s aim is to assess the effectiveness of the electronic application that is utilised in the oral health school programme to increase the quality of the information relating to the recording of dental health data in schools. Methods: This study used a pre-test and post-test one-group design, and the sample consisted of 37 oral health programme managers in schools who were chosen via simple random sampling. The data in this study was analysed using the Wilcoxon signed-rank test. Results: The results showed that the use of the electronic application as part of the oral health scheme influenced the quality of the information when details were recorded and reported. This can be seen in the rise in the standard of the information that was noted and disclosed when comparing data before and after using the electronic application; the average value of 1.54 (standard deviation=1.45) increased to an average value of 3.58 (standard deviation=2.84) with a significance level of 0.000 (p<0.05). Conclusion: The electronic application used in conjunction with the oral health programme was effective in raising the quality of dental health records in schools.

Abstract

Background: Fixed orthodontic appliances, such as Edgewise and Straightwire techniques, can increase the amount of plaque retention containing Streptococcus mutans (S. mutans), which can lead to white spot lesions. Purpose: The aim of this study is to analyse the correlation of fixed orthodontic treatment with Edgewise and Straightwire techniques on the incidence of white spot lesions and accumulation of S. mutans. Methods: The samples consisted of three groups: control group (n=8), Edgewise technique group, and Straightwire technique group. We observed the samples at the sixth month and eighth month of the treatment, after the installation of the fixed orthodontic appliances. The observation of white spot lesions with caries detector was applied in all regions. Bacterial swabs were acquired in the lateral incisor region, then a bacterial culture procedure was carried out on selective media of S. mutans, and then a bacterial count was performed. The data was analysed using two-way ANOVA, the post-hoc least square differences test, and the Pearson’s correlation test. Results: The number of white spot lesions in the Edgewise group was higher than in the Straightwire group in the sixth and eighth month of treatment with insignificant difference (p>0.05). The number of S. mutans bacteria increased in all groups, but there were no significant differences (p>0.05). There was no significant relationship between the number of white spot lesions with the accumulation of S. mutans between groups (p>0.05). Conclusion: The Edgewise and Straightwire techniques increase the incidence of white spot lesions but accumulation of S. mutans with the incidence of white spot lesions has no relationship.

Abstract

Background: Telescopic overdenture is a prosthesis consisting of a primary coping, or an inner crown, that is attached to a supporting tooth in the oral cavity, and a secondary coping, or an outer crown, attached to a denture, which must be compatible with the primary coping. Purpose: The purpose of this study was to restore function and aesthetics and uplift the psychological status of the patient by fabrication of a fixed removable prosthesis using the existing abutment teeth as a telescopic overdenture. Case: A 36-year-old female came to the Prosthodontic RSGM UNAIR speciality clinic on her own volition to make front dentures for her upper and lower jaws after a traffic accident one and a half years ago. The patient had an arch bar installed two months after the accident, which was removed after two months. The patient wanted new dentures to improve both her ability to eat and her appearance. Case Management: Preliminary treatments performed were; maxillary and mandibular scaling and root planing; crown lengthening of tooth 15; extraction of teeth 16, 41, 42, and 43; and alveolectomy of the mandibular anterior region. Before the definitive treatment to improve the aesthetic appearance could be carried out, the first step was to make maxillary and mandibular transitional dentures. These were to be used while waiting for healing to occur, following the socket preservation in the mandibular area. Then, for the definitive restoration, we used telescopic overdenture for the maxilla and a removable partial denture for the mandible. Conclusion: Telescopic overdenture is recommended for patients who need good aesthetics for anterior tooth loss. Telescopic overdenture uses double crowns as the retentive elements, which give better aesthetic results compared to clasps, thereby improving the psychological status of the patient. In addition, they have better retention and stability compared to conventional complete dentures.

Abstract

Background: Taste disorders often occur in the elderly, which can have serious consequences on their health status. Zinc and saliva volume have a role in maintaining taste acuity, especially in the elderly. Purpose: This study was to determine the correlation between salivary zinc levels, salivary volume, and taste disorders in elderly patients. Methods: This was a cross-sectional research. Elderly patients with and without taste disorders were included in this study. Salivary zinc levels were measured using the Atomic Absorption Spectrometry (AAS) method. Salivary volume was measured using the spitting method. The correlation between salivary zinc levels, salivary volume, and taste disorders was analysed using the chi-square test. Multivariate analysis was performed to control for confounding variables with logistic regression. Results: Based on our findings, no significant correlation was determined between the levels of zinc in saliva and taste disorders. However, there was a significant correlation between salivary volume and taste disorders. Salivary volume and smoking were determined to be associated with taste disorders. Conclusion: This research showed that salivary zinc levels were not correlated with taste disorders; on the contrary, salivary volume was correlated with taste disorders. Smoking was determined to be a confounding variable on taste disorders in elderly patients.
