Abstract

Background: Therapy for chronic ulcer in diabetic patient is by modifying local inflammation response using drugs that acts as immunomodulator, neuromodulator and growth factors stimulator. Topical zinc is one of drug that can modifiy local inflammation response, immunostimulation or immunosuppresion. Purpose: This study was to prove about the number of macrophage in oral ulcer between normal and diabetes microscopically and the difference if treated by 1% ZnSO4 gel topically. Method: Ulcer in lower labial mucosa was made in normal and diabetic Wistar rats (induced by STZ), then applied 1% ZnSO4 gel and CMC-Na gel as control. They were decapitated in third and fifth day and specimen was made by processing lower labial mucosa Result: Microscopically, the result showed the number of macrophages in oral ulcer in diabetic condition was significantly higher than normal and the application of 1% ZnSO4 increased the number of macrophages in fifth day. Conclusion: The number of macrophages was higher in diabetic than normal condition, and was proven that topical application of 1% ZnSO4 increased the number macrophages of oral ulcer diabetic and normal condition.

Abstract

Background: Preservation of sockets is a procedure aimed to reduce bone resorption after tooth extraction. One of the most commonly used xenograft materials is demineralized freeze-dried bone bovine xenograft (DFDBBX). Meanwhile, one of the key regulations in osteoclast genesis process is RANKL bond. A decrease in the number of RANKL expressions can suppress the osteoclast genesis process so that bone resorption can be prevented. The combination of Moringa leaf extract and DFDBBX, as a result, is expected to decrease the number of RANKL. Purpose: This study aimed to measure RANKL expressions in tooth extraction socket treated with Moringa leaf extract combined with DFDBBX. Methods: Fifty six Cavia cobaya rats were divided into eight groups. The first group was a control group with PEG administration onto their extraction sockets. The second group was a treatment group with DFDBBX administration. The third group was a treatment group with Moringa leaf extract administration. The fourth group was a treatment group induced with a combination of DFDBBX and Moringa leaf extract. Examination then was performed on days 7 and 30. After 7 and 30 days, those Cavia cobaya rats were executed and tested with immunohistochemical techniques. Further research data collected then were tested with one-way ANOVA. Results: There were significant differences between the control group and the groups induced with the combination of Moringa leaf extract and DFDBBX. On days 7 and 30, the groups induced with the combination of Moringa leaf extract and DFDBBX had the lowest number of RANKL expressions. Conclusion: The combination of Moringa leaf extract and DFDBBX can decrease the number of RANKL expressions in Cavia cobaya rats on the day 7 and day 30 after tooth extraction.

Abstract

Background: Periodontitis is an infection in tooth-supporting tissues caused by a specific microorganism, Porphyromonas Gingivalis (PG), which can trigger collagen destruction. Generally, periodontal therapy employs a combination of mechanical (scaling root planning/SRP) and chemical (antibiotics) remedies, the latter of which can cause bacterial resistance. On the other hand, shark liver oil contains active natural ingredients such as alkylglycerols, squalene, squalamine, and omega-3, which have antibacterial and antioxidant effects. Purpose: This study aims to determine the impact of shark liver oil on fibroblasts and collagen density in the periodontal ligament of Wistar rats induced with PG. Methods: This study represents a laboratory experiment with post-test only control group design. The research subjects consisted of 35 Wistar rats divided into five groups, namely; a negative control group (K-); a positive control group with PG induction (K+); and three treatment groups induced with PG and shark liver oil once a day for seven days at varying doses of 0.2 g/gBB (P1), 0.3 g/gBB (P2), and 0.4 g/gBB (P3). Following treatment, the subjects were euthanized. The number of fibroblasts was then histologically examined with Hematoxylin Eosin (HE). Meanwhile, the collagen density was histologically analyzed with Masson’s Tricrome. Fibroblast cells were observed through a microscope at 400x magnification. Data was statistically analyzed with a one-way ANOVA and post hoc LSD. Collagen Density scoring was then performed. The results were analyzed with a non-parametric Kruskal-Wallis test (p=0.05), and subsequently with a Mann-Whitney U test (p<0.05). Results: The number of fibroblasts in the periodontal ligament areas of each group were 18.6 ± 1.21 for K-; 12 ± 1.26 for K;16.8 ± 1.72 for P1; 17.1 ± 1.94 for P2; and 23.16 ± 2.78 for P3. The results also indicated that there were significant differences between K- with K+ and P3, K+ with P1, P2, and P3, as well as P3 with P1 and P2. However, there was no significant difference between K- and P1 and P2 or P1 and P2. The results showed that collagen density in the negative control group did not significantly decrease compared to that in the positive control group in which PG was induced. Meanwhile, collagen density in all three treatment groups following doses of 0.2 g/gBB, 0.3 g/gBB, and 0.4 g/gBB being administered significantly increased compared to that in the negative control group and the positive control group subjected to PG induction. Conclusion: Shark liver oil can significantly increase fibroblast cells and collagen density in the periodontal ligament of Wistar rats induced with PG.

Abstract

Background: Adjustment disorder is a temporary psychological condition related to emotional responses or behaviour in reaction to stress resulting from certain changes in a specific period of an individual’s life yet which does not significantly affect his/her daily life. Recurrent aphthous stomatitis (RAS) constitutes recurrent inflammation of the oral mucosa, in the form of an ulcer, frequently associated with psychological stress. Occasionally, a patient does not realise that she/he is suffering from a psychological disorder until the emergence of clinical symptoms, among them recurrent ulcers the causes of which are unknown. Purpose: This article presents a case of adjustment disorder diagnosed from symptoms observable in the oral cavity. Case: The case involved a 21-year-old student who presented with the symptoms of large, painful ulcers on her tongue, the inside of her cheek, and the floor of her mouth. These symptoms had been observable for one month but remained untreated. The patient only ate once a day or even once every two days. An introverted personality, she did not associate with other people. Case management: The procedure covered anamnesis, clinical examination, blood laboratory tests, total immunoglobulin E (IgE), an Antinuclear Antibody (ANA) test, bacterial and fungal culture in ulcus, questionnaire screening on psychological disorders, cortisol level examination and referral to a psychiatrist. Symptomatic therapy administered to the patient led to recovery of the ulcer in 29 days. Conclusion: RAS can be triggered by psychological stress which induces changes in the immune system and oral mucosa tissue.

Abstract

Background: Children demonstrating autistic spectrum disorders tend to be uncooperative when receiving dental treatment. Actions as simple as brushing the teeth with a prophylactic brush can constitute complex processes for children with such conditions. Applied behavior analysis (ABA) can train children in new positive behavior and it is, therefore, anticipated that an ABA-based approach iscapable of influencing the behavior of individuals with autistic spectrum disorder. Purpose: This study aimed to assess the effectiveness of the ABA-based approach for autistic children during dental brushing procedures. Methods: The research constituted a quasiexperimental single subject investigation of children presenting autistic spectrum disorders who attended the Lembaga Pendidikan Autisma Prananda, Bandung. Potential changes in the behavior of subjects were monitored four times during treatment with a one-week interval between consultations. Those subjects satisfying the inclusion criteria consisted of 11 boys and 4 girls. The data analysis used in this study consisted of an ANOVA test and a non-parametric Kruskal-Wallis test with a p–value < 0.005. Results: Changes in scores between the initial and final consultations were statistically significant with a p-value (0.269) <0.05. Statistically significant differences existed between changes in the behavior of level 1 and level 2 autistic subjects. Conclusion: An ABA-based approach effectively changes the behavior of autistic children with regard to prophylactic brushing. Children with level 1 autistic spectrum disorder demonstrate greater capacity to follow instructions and consistently implement a prophylactic brushing technique.

Abstract

Background: Bulk fill packable composite that can be applied to a depth of 4mm in cavities is widely used in posterior teeth restoration. Unfortunately, this composite is subject to potential microleakage which occurs due to erosion resulting from the consumption of carbonated drinks containing carbonic acid. Nevertheless, microleakage can be reduced by bonding applications the etch technique of which is divided into two forms; self-etch bonding and total-etch bonding. Purpose: This study aims to determine the difference in microleakage between total-etch and self-etch bonding in bulk fill packable composite following carbonic acid immersion. Methods: This study constitutes experimental laboratory research utilizing 28 incisors bovine teeth which were cleaned, immersed in 0.01% NaCl, and randomly divided into four groups. The cervical area of the teeth of all groups were prepared through the creation of cylindrical shapes 2mm in diameter and 3 mm deep. Groups I and III used total-etch bonding, while groups II and IV used self-etch bonding. Groups III and IV were control groups, whereas groups I and II were treatment groups (immersed in carbonic acid) for 24 hours. Thermocycling was carried out in all groups which were subsequently immersed in 1% methylene blue for 24 hours after which the teeth were cut in a buccolingual direction using a diamond disc wheel. Microleakage was subsequently evaluated by calculating the amount of methylene blue passing between the restoration wall and cavity using a Stereomicroscope and scanning electron microscope (SEM). The data was then analyzed using Kruskal Wallis and Mann Whitney U tests. Results: There was a significant difference between the control groups and treatment groups (p<0.05). The microleakage in Group 2 was higher than that of other groups. Conclusion: The microleakage of total-etch bonding was lower than self-etch bonding in bulk fill packable composite after carbonic acid immersion.

Abstract

Background: The Moyers and Tanaka-Johnston analyses, both of which were developed through research into the Nordic-Caucasoid population, constitute the most widely used non-radiographic mixed dentition analyses. Application of these prediction methods to other populations has been extensively investigated, although their suitability to the Arab population resident in Indonesia has rarely been studied. Purpose: This study aimed to investigate the reliability of Moyers and Tanaka-Johnston analyses of the Arab population of Pekalongan, a city in Central Java, Indonesia. Methods: This research constituted an observational study incorporating a cross-sectional design of 33 subjects who willingly signed an informed consent form. Their actual tooth size was determined in accordance with the inclusion criteria and then compared with the predictive tooth size values of the Moyers and Tanaka-Johnston analyses. Results: Comparison of mean values indicated that the predictive values of Moyers 75% (YM) and Tanaka-Johnston (YT) were higher than the actual value (Y). The reliability test result confirmed a value of k = 0.026 for the Y-YM ratio; and k = 0.025 for YT-Y ratio. The calculation results for the mandible indicated a k-value of 0.000 for both types of comparisons between YM-Y and YT-Y. The Moyers 75% prediction for maxilla had a higher reliability value than that of Tanaka-Johnston. The Shapiro-Wilk normality test applied to Y, YM, and YT in the maxilla and mandible indicated that data was normally distributed (sig > 0.05). A Levene's test of homogeneity was conducted and produced homogeneous data (sig > 0.05) with values of 0.333 for Y, 0.516 for YM, and 1.000 for YT. An ANOVA test showed Y-YM and Y-YT to have insignificant differences (p<0.05). This result caused comparative tests to determine both analysis eminence in predicting canine and premolar values according to the study sample not conducted. Conclusion: The Moyers 75% and Tanaka-Johnston analyses were reliable because the values produced differed slightly from the actual values. This study concluded that Moyers and Tanaka-Johnston analyses remain valid means of calculating mixed dentitions.

Abstract

Background: Inflammation of the pericorona due to lower third molar impaction (LTMI) is often diagnosed as pericoronitis. Expression of cyclooxigenase-2 (COX-2) and caspase-1 may be induced by lipopolysacharide (LPS) and cause pyroptosis with minimal inflammation. When LPS activates toll-like receptor (TLR-4), NOD-like receptors containing domain pyrin 3 (NLRP3) inflammasome will activate the release of pro-caspase-1 to caspase-1, followed by the secretion of interleukin (IL)-1β. IL-1β and IL-23 which induces CD4+ Tcells (Th17) to produce IL-17 as a pro-inflammation cytokine. Purpose: This study aimed to identify the respective roles of COX2, caspase-1 and IL-17 in pericoronitis inflammation of the pericorona due to LTMI. Methods: Frozen section samples were produced through LTMI pericorona tissue biopsy using material provided by the Dental and Oral Clinic at Muwardi Hospital, Surakarta. The paraffin block produced was subsequently cut using a clean microtome with the resulting thin slices being placed on an object glass coated with polylysine. A diagnosis of pericoronitis was subsequently made by a pathologist. Immunohistochemical staining for COX-2, caspase-1 and IL-17 was carried out by indirect tyramide signal amplification (TSA) method. Photos were obtained by means of 100X, 200X, 400X and 1000X objective lensed microscopes to qualitatively assess the above mentioned protein expressions. T-Test was conducted in order to establish the difference in expression between the control group and pericoronitis due to LTMI. Results: The presence of a brownish yellow color indicated the expression of COX-2, caspase-1 and IL-17 in pericorona epithelial cells which visible expression categorized as moderate (30-70%). The mean expression of COX-2, caspase-1 and IL-17 was categorized as mild and there was no significant difference between the expression of the three proteins. Conclusion: COX-2, caspase-1 and IL-17 play an important role in the phyroptosis signal of LTMI pericoronitis in cases of low inflammation.

Abstract

Background: One purpose of operative dentistry is the maintenance of healthy pulp by reducing the need for root canal treatment and the possibility of undesirable scenarios such as tooth loss. Propolis is a plant-derived substance that contains a resin produced by honeybees belonging to the Apis mellifera species. Purpose: This study aimed to investigate the effect of a combination of calcium hydroxide (Ca(OH)2) and propolis extract on odontoblast-like cell proliferation in Wistar rats (Rattus norvegicus). Methods: This research constituted a true experimental laboratory-based investigation with post-test control group design. Thirty Wistar rats were randomly divided into six groups. The first molar pulp of each sample was perforated on occlusal surfaces using a low speed round bur. On day 3, the samples were divided into six groups (n=10): Group I: control; Group II: Ca(OH)2 + 11%; propolis extract; Group III: Ca(OH)2 + aquadest, and on day 7: Group IV: control; Group V: Ca(OH)2 + 11% propolis extract; Group VI: Ca(OH)2 + aquadest. All samples were filled with restorative material. They were subsequently sacrificed after 3 and 7 days post-pulp capping administration and the afflicted tooth extracted for hematoxylin and eosin (H&E) staining. The resulting data was subjected to statistical analysis to ascertain the proliferation of odontoblast-like cells. The significance of differences between the groups was determined by a one-way ANOVA test followed by a post hoc Tuckey HSD. A p-value <0.05 was considered to be significant. Results: On day 3, a significant difference existed between group II (Ca(OH)2–propolis) and group I (control group) and group III (Ca(OH)2–aquades), whereas Ca(OH)2–propolis revealed that the proliferation of odontoblast-like cells was higher. Meanwhile, on day 7, there was a significant difference between all groups whereas, with regard to Ca(OH)2–propolis, the proliferation of odontoblast-like cells in group V was higher. Conclusion: Application of combination of Ca(OH)2-propolis extract can increase the proliferation of odontoblast-like cells in pulp tissue on days 3 and 7.

Abstract

Background: The mandible is one of the bones most affected by facial fractures commonly resulting from trauma to the face. The ultimate goal of treatment is to re-establish the pre-injury dental occlusion (bite), mandibular anatomy and jaw function of the patient. Treatment approaches range from conservative non-invasive management by ’closed’ reduction and immobilization using intermaxillary fixation (IMF) to the more invasive surgery-based ’open’ reduction incorporating an internal fixation approach. Purpose: The purpose of this case series was to describe the close reduction method as a form of treatment in cases of neglected mandibular fracture. Cases: Four cases of single or multiple mandibular fracture were presented. Case management: All of the cases were managed using a closed reduction method and IMF. Conclusion: A closed reduction method in this case series produced encouraging results and could be considered an alternative in the treatment of neglected mandibular fractures with displacement.
