Abstract

Background: X-ray examinations are still a frequent diagnostic tool used by doctors in Indonesia. However, there is an apparent lack of descriptive data regarding the size and location of the maxillary sinus in Indonesian people. Objective: The aim of this study is to provide descriptive data on the size and location of the maxillary sinus among patients in the city of Bogor, West Java, Indonesia. Methods: Sixty eligible subjects aged 17 to 70 years old were randomized into six groups: male and female patients between 17 and 25 years old; male and female patients between 26 and 45 years old; and male and female patients aged 46 or older. Radiographic pictures were taken using the X-mind Novus Digital Panoramic X-ray unit and data were measured using the software Digora for Windows. Results: Using an analysis of variance, we found that men have significantly larger maxillary sinus dimensions than women (79.05 mm compared to 66.33 mm). It also reveals that there are significant differences (p<0.05) between male and female groups; whereas 2 groups aged less than 46 years old are significantly different with group aged 46 years or older in both gender. Conclusion: The study demonstrates that the size and location of maxillary sinus differ significantly between men and women in Bogor and that they follow a specific trend.

Abstract

Background: Pain is a common problem encountered after fixed orthodontic appliance placement. Pain from orthodontic treatment can come from ischemia, inflammation, and edema in the periodontal ligaments that were depressed. Objectives: To determine whether there are differences in the pain reduction associated with chewing gum, taking acetaminophen, and gargling green tea after fixed orthodontic appliance placement. Methods: This study is a quasi-experiment with a controlled randomized post-treatment approach using 40 subjects. The subjects were consecutively selected and then randomly assigned into four equal groups: a group assigned to chewing gum, a group assigned to take acetaminophen, a group assigned to gargle green tea, and a control group. The level of pain was measured using a Visual Analogue Scale (VAS). A one-way ANOVA test was used to analyse differences between the groups. Results: The VAS scores of the chewing gum and acetaminophen groups were lower than the green tea and control groups. At 24 hours after fixed orthodontic appliance placement, only the chewing gum group reported a decrease in the amount of pain experienced. Overall, the chewing gum group reported the lowest pain scores compared to other groups. However, there was no overall statistically significant difference between the chewing gum and acetaminophen group (p>0.05). Additionally, there was no statistically significant difference in the amount of pain reduction experienced by the green tea group and the control group (p>0.05). There was a significant difference in the amount of pain reduction reported between the chewing gum or acetaminophen groups and the green tea group (p<0.05). Conclusion: There was no significant difference between chewing gum and taking acetaminophen in the amount of pain reduction experienced after fixed orthodontic appliance placement, but gargling with green tea was found to be significantly less effective in reducing pain. Because it has fewer side effects, chewing gum may be a more preferable alternative to taking acetaminophen to reduce pain after fixed orthodontic appliance placement.

Abstract

Background: Enterococcus faecalis is the frequent cause of oral infections, such as periodontitis, infected root canals, and peri-radicular abscesses. Pineapple (Ananas comosus) fruit contains bromelain, one of proteolytic enzymes associated with several health benefits. Bromelain has been shown to promote healthy digestion, stimulate the immune system, improve cardiovascular conditions, and accelerate wound healing. Bromelain compounds possess anti-inflammatory and anticancer properties and exhibit antibacterial activity. Objective: To analyze the enzymatic activity of bromelain extracted from pineapple hump and investigate the antibacterial effect of bromelain against E. faecalis. Methods: Pineapple hump was dried and extracted with maceration technique. Further purification was obtained by ammonium sulfate fractionation, dialysis and ion exchange chromatography. Minimum inhibitory concentration (MIC) tests using diffusion and dilution techniques tested the antibacterial activity of the bromelain extract on E. faecalis. A one-way analysis of variance (ANOVA) test analyzed the significance of the differences in the E. faecalis inhibition zones after treatment with a range of bromelain extract concentrations. Differences were considered statistically significant if p < 0.05. Results: The specific activity of bromelain in the crude extract was 62.89 U/mg. Furthermore, bromelain activity using ammonium sulfate fractionation was 50.99 U/mg, dialysis was 54.59 U/mg, and ion exchange chromatography was 152.38 U/mg. The bromelain extract showed effective inhibitory and bactericidal activity against E. faecalis. The results of the inhibition test using a bromelain extract purified by ion exchange  chromatography demonstrated that a concentration as small as 12.5% was effective in inhibiting the growth of E. faecalis (p < 0.05). Conclusion: The highest enzymatic activity of bromelain was found after purification with ion exchange chromatography. Bromelain exerted an antibacterial effect against a potent endodontic pathogen, but further studies are needed to explore this effect.

Abstract

Background: Pomegranate (Punica granatum) fruits are commonly regarded as medicinal plant in Indonesia, and the polyphenols found in pomegranate juice (punicalagin and ellagic acid) have been shown to have antibacterial properties. Objectives: Using monospecies and multispecies biofilms, we sought to examine the effects of pomegranate juice on the viability of three periodontal pathogens: Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Treponema denticola. Methods: Biofilm assays were performed using crystal violet. Pomegranate juice was obtained from pomegranates using a juicer, and the juice was then diluted into different concentrations with phosphate saline buffer. The three pathogens were cultured in both monospecies and multispecies plates. Pomegranate juice was then added to each biofilm well. These were then incubated for 1h, 6h, or 24h, after which the optical density (OD) of the biofilm mass was measured using a microplate-reader (490 nm). Biofilm without treatment was used as a negative control and 0.2% chlorhexidine gluconate as a positive control. Data were analyzed with a one-way ANOVA; the level of significance was set at p<0.05. Results: Compared to the negative control, biofilm mass was significantly decreased after treatment with pomegranate juice across all concentrations and incubation times, for both monospecies and multispecies biofilm (p<0.05). The best results were achieved with P. gingivalis biofilm, with 100% concentration (OD 0.34 ± 0.03); A. actinomycetemcomitans, 50% concentration (OD 0.22 ± 0.01); and T. denticola, with 25% concentration (OD 0.87 ± 0.08), as well as with a multispecies biofilm with a 50% concentration in 1h incubation time (OD 0.09 ± 0.02). Conclusion: Pomegranate juice effectively inhibited the biofilm formation of P. gingivalis, A. actinomycetemcomitans, and T. denticola. Pomegranate juice may therefore be used as an alternative therapy in preventing periodontal disease. Additional research should explore this effect in an environment that mimics oral cavities.

Abstract

Background: Angiosarcoma is a rare malignant tumor, which most often occurs in the skin and soft tissue. Its occurrence in the head and neck region, and the intraoral region in particular, is uncommon. The aim of this case report is to highlight the importance of histopathological examination and to underscore the characteristic features of angiosarcoma. Case report: A 52-year-old female presented with a growth in the right maxillary portion of the interdental region of her molar teeth. The growth had been present for approximately one month. A computerized tomography (CT) scan showed metastatic tumors in the lungs, liver, bone, and soft tissue of maxillary gingiva. Intraoral examination found a soft and mobile pedunculated ovoid mass at the right palatal gingiva; the mass was reddish-blue in color. An incisional biopsy was performed to confirm the diagnosis and plan for further treatment. Histopathologic examination revealed malignant endothelial cells in a vasoformative growth pattern, with numerous vascular channels lined with neoplastic endothelium-forming intraluminal buds, projections, and papillae. These projections were interspersed with the tumor cells. Immunohistochemistry analysis showed these endothelial cells demonstrated strong positive immunoreactivity with CD31, factor VIII, and FLi-1. A diagnosis of angiosarcoma was made. Discussion: Because intraoral angiosarcoma is rare and its clinical presentation can resemble other vascular lesions, it can be a challenging diagnosis for clinicians and pathologists. In the present case, the diagnosis of intraoral angiosarcoma was made based on clinical and histopathology findings. The microscopic features of malignant endothelial cells and the presence of intraluminal projections, supported by positive immunoreactivity with CD31, factor VIII, and FLi-1, confirmed the diagnosis. Conclusion: Angiosarcoma poses a diagnostic challenge to dental practitioners and oral pathologists due to the rarity of occurrence in the oral cavity. Histopathological examination is critical for an accurate diagnosis.

Abstract

Background: The perception that the specialty of prosthodontics has changed over time is subjective and largely based on personal belief, with little data to uphold this view in the literature. Objectives: The aim of this study was to compare the frequency of presentation categories at each International College of Prosthodontists Conference from 1999 to 2017 and identify trends. Methods: Available ICP Conference Programs were sourced from the ICP Administration and the titles of all presentations reviewed and catalogued into one of 13 presentation categories. The number of presentations in each category was expressed as a percentage of the total number of presentations for each conference and statistically analyzed for trends throughout the study period. Results: 69.61% of all presentations from all conferences were categorized as one of implant dentistry; materials, CAD-CAM and digital technologies; removable prosthodontics and edentulism; or fixed prosthodontics. 46.38% were categorized as implant dentistry or materials, CAD-CAM and digital technologies. The frequency of presentations of fixed prosthodontics significantly decreased while the frequency of implant dentistry; maxillo-facial prosthodontics; geriatric dentistry and medically compromised patients; and clinical case presentations and treatment planning significantly increased (p<0.05) over the study period. Conclusion: The ICP Conference presentation titles reviewed from 1999 to 2017 maintained a focus on implant dentistry and materials, CAD-CAM and digital technologies alongside a diverse range of other topics. Throughout the study period, the frequency of presentations of fixed prosthodontics significantly decreased while the frequency of presentation of implant dentistry; maxillo-facial prosthodontics; geriatric dentistry; and clinical case presentations and treatment planning significantly increased.

Abstract

Background: Biofilms are involved in a wide variety of microbial infections, including dental caries and periodontitis. The use of probiotics has been a promising prevention and treatment modality with which to combat biofilm-related diseases in the oral cavity. The probiotic Lactobacillus reuteri has been proven to reduce gingivitis and plaque index inside the oral cavity. These bacteria can be found in the digestive system and also in the human oral cavity. Objective: The aim of this study was to identify L. reuteri in the saliva of Indonesian young adults. Methods: Forty saliva samples were collected from 18–24 year-old Indonesian subjects. DNA extraction was performed, and then, the identification of L. reuteri was accomplished using PCR. Six subjects showed positive results. The positive samples were cultured in Rogosa Agar for 24 hours at 37°C anaerobically. Several single colonies were further cultured separately in broth medium before DNA extraction and PCR identification were performed. The four thickest bands were selected for DNA sequencing. Results: An analysis performed using BLAST showed that two of the L. reuteri strains obtained from the Indonesian saliva isolates had 96% (isolate 3.11) and 95% (isolate 5.14) values. This confirmed the presence of new strains based on average nucleotide identity (ANI). The isolate strains of 3.11 and 5.14 have been registered at DDBJ/EMBL/GenBank under the accession number LC382415 and LC382416, respectively. Conclusion: L. reuteri novel strain can be isolated from the saliva of Indonesian young adults.  Further studies involving biochemical tests and phenotypic analysis are needed to better understand these new L. reuteri strains.

Abstract

Background: Dentists often encounter patients with worn dentures that still feel comfortable even though the patients have lost the supporting tissue heights due to physiological and pathological resorption. Loss of denture retention, stability, and occlusal vertical dimension are most often caused by alveolar bone resorption. Dentures that are loose because of poor adaption to the supporting tissues should be relined. Chair-side procedures provide immediate resolution, avoiding the edentulous period of time accompanying laboratory relines. Case Report: A 70-year-old male edentulous patient came to the Prosthodontic Clinic, Faculty of Dentistry, Trisakti University, Jakarta, Indonesia. The patient had been wearing the upper and lower dentures for approximately eight years. The patient had alveolar ridge resorption, which causes loss of retention, stability and vertical dimension. After the problems were thoroughly diagnosed and corrected, a chair-side denture relining with an open-mouth technique was used. Conclusion: Direct relining in a single visit helped the complete denture to regain its retentiveness, allowing for prolonged the use of the worn denture. It also adjusted occlusal vertical dimension to improve the occlusal support and esthetics.

Abstract

Background: The dimensional stability of alginate impression material is very important for obtaining an accurate cast. Seal bag storage is one way to maintain dimensional stability of the impression material. Objectives: This research aims to compare the dimensional stability of alginate impressions between imprESSIX Color Change (Alginate A), Algeniux Normal Set Major (Alginate B), and Aroma Fine Plus Normal Set (Alginate C). The alginate impressions were stored in seal bags for 0 min, 10 min, 3h, 24h, 72h, 120h, and 168h. Method: Sixty-three gypsum cast samples were obtained from a master die using 3 different alginate impression materials.  The alginate impressions were stored in separate seal bags for each of the seven different time intervals, then the samples were poured with gypsum type III.  The buccal cusp length from right first molar to left first molar was measured for each gypsum cast sample using calipers and compared with the master die. The data were analyzed with two-way ANOVA followed by post hoc LSD test. Results: The distance between the mesial buccal cusps of the right and left first molar was 52.280 mm for the master die.  Gypsum cast samples of alginate A and B showed shorter lengths compared to master die, but the difference was not significant (p>0.05). A significant difference in dimensional stability was observed for alginate C (p<0.05) after 120h (52.080 mm) and 168h (52.057 mm). Conclusion: Dimensional stability of alginate impression was influenced by alginate composition and seal bag storage time. Seal bag storage could hold the dimensional stability of alginate A and B up to 168h, but for alginate C, the stability only lasted for 72h.

Abstract

Background: Temporomandibular disorder (TMD) is a common term used to describe the problems related to masticatory muscles, joints, and supporting tissues. TMD commonly causes orofacial pain and has been the subject of considerable research in the field of dentistry. The treatment chosen for patients who have TMD is largely determined by the knowledge of general dental practitioners. Objectives: The purpose of this research was to assess the understanding of TMD pathophysiology by such practitioners. Methods: Questionnaires were distributed randomly to general dental practitioners in private offices and hospitals in the area of Jakarta, Indonesia. The answers on the returned questionnaires were compared to those of TMD experts. Results: Of the 117 questionnaires distributed to general dentists, 105 were returned (89.7% response rate). The results showed an overall level of knowledge of TMD pathophysiology of 25%. Conclusion: The majority of general dental practitioners in Jakarta lack knowledge of TMD pathophysiology
