Black pepper (<em>Piper nigrum L </em>) is one of herbal plants that compose antibacterial compounds including alkaloids, flavonoids, tannins, and essential oils. This study aims to determine the effect of black pepper (<em>Piper nigrum L.</em>) extract to inhibit of <em>Streptococcus mutans</em>growth. Black pepper extracts ware made by using maceration method. The effect of black pepper extract ( <em>Piper nigrum L. </em>) in inhibition of <em>Streptococcus mutans</em>growth by using the disc diffusion method on Mueller Hinton Agar media. The concentration of black pepper ( <em>Piper nigrum L.</em>) extracts used in this study were 6.25%, 12.5%, 25%, 50%, 75%. The results of this study were analyzed by using the one-way ANOVA test showed that there was significant effect of black pepper extract on <em>Streptococcus mutans</em> growth with p-value (p &lt;0.05), and then the data was tested by Least Significant Difference (LSD). Conclusion of this study showed that there was an effect of black pepper ( <em>Piper nigrum L.) </em>extract in inhibition of <em>Streptococcus mutans</em> growth with concentrations 75% is the optimum concentration which value 16.8 mm.</p> 2020-07-09T00:00:00+07:00 Copyright (c) 2020 Dentika Dental Journal The Variation of Pulp Canal Configuration in Mandibular Posterior Teeth Using Cone Beam Computed Tomography in Indonesia Subpopulation Mongoloid Race 2020-05-12T11:07:34+07:00 Trelia Boel Dewi Kartika Dennis <p>It is important to understand pulp canal configuration to have a successful endodontic treatment. Cone Beam Computed Tomography (CBCT) radiography is able to assess the pulp canal configuration, especially on the lingual/palatal, compared to the periapical radiography. The objective of the research is to know the prevalence pulp canal configuration of mandibular molar teeth in Indonesia subpopulation Mongoloid race using CBCT radiography. This research is a descriptive survey with a cross-sectional approach, using 38 CBCT radiographs from the patients undergoing dental treatments in hospitals in Medan. The subjects were selected based on research criteria; then their CBCT radiographs were interpreted and analyzed. The result shows the existence of mandibular mesial root type 2-1 (28.94%), 1-2-1 (5.26%), 2-2 (55.26%), 2-1-2-1 (2.64%), 3-2 (5.26%), 3-1 (2.64%), distal root type 1-1 (36.84%), 2-1 (23.68%), 1-2-1 (15.79%), 1-2 (2.63%), 2-2 (13.17%), 2-1-2-1 (5.26%), 1-3-1 (2.63%). The distolingual root of mandibular first molars consisted of type 1-1 (100%). Mesial root of mandibular second molars of type 1-1 (2.63%), 2-1 (50%), 1-2-1 (5.26%), 2-2 (36.85%), 2-1-2-1 (2.63%), 1-2-1-2 (2.63%), distal root type 1-1 (57.89%), 2-1 (15.79%), 1-2-1 (13.16%), 2-2 (10.53%), 2-1-2 (2.63%). This variation of the pulp canal can be influenced by the shape of roots. A flat root usually contains pulp canal configuration type II – VIII Vertucci, similarly to mandibular molar mesial canals. As a summary, there is a variation of pulp canal configuration in mandibular first and second molars on Indonesian Mongoloid race, as seen from the CBCT radiographs.</p> 2020-07-20T00:00:00+07:00 Copyright (c) 2020 Dentika Dental Journal The Comparison of Smile Aesthetic of Males and Females Based on Buccal Corridor and Smile Arc 2020-04-28T20:06:28+07:00 Lina Hadi Puspa Maya Br Sembiring Zulfan Muttaqin <p>In performing the orthodontic treatments, patients aim to improve their smile esthetical features which are influenced by the position, size, shape, and color of teeth. However, in recent decades, several aesthetical features that have been studied are buccal corridor, smile arc, incisor display, and gingival display. In this study, 32 subjects composed of 16 males and 16 females were photographed from the front-site by using a DSLR camera within smiling states. Smile arc and buccal corridor measurements were performed via Corel Draw 12 program. The extra broad and broad characteristics were found in male subjects which were 31.2% and 18.8% respectively, while the female subjects had a higher broad proportion of 43.7% and extra broad for 6.3%. The smile arc features in male subjects were found were straight smile (34.4%) and consonant smile (15.6%), in contrast, the percentage of the female students had a higher consonant smile (31.3%) than straight smile (18.8%). This study confirmed similar findings regarding the domination of the buccal corridor broad in the female population, whereas the extra broad is dominated by males. By contrast, the smile arc consonant is dominated by females, while the straight feature is dominated by males.</p> 2020-07-22T00:00:00+07:00 Copyright (c) 2020 Dentika Dental Journal Minor Oral Surgery and Dental Extraction Procedures Management of Patients with Antithrombotic Drugs Administration 2020-03-30T10:40:47+07:00 Dwi Riski Saputra <p>Patients who are undergoing antithrombotic drugs therapy whether it was alone or in combination can increase the bleeding complications after performed minor oral surgery or tooth extraction. If the termination of using antithrombotic drugs to prevent bleeding isn’t right, it’ll trigger thrombosis. Therefore appropriate consideration is needed in the management of patients undergoing antithrombotic drug therapy that requires minor oral surgery or dental extraction. The purpose of this literature review is to examine management of minor oral surgery and dental extraction procedure in patients with antithrombotic drugs. Management of minor oral surgical procedures and tooth extraction in patients using antithrombotic drugs must be adjusted to the type of antithrombotic drugs used by the patient. Patients who use antithrombotic drugs are advised to undergo minor oral surgery or tooth extraction treatment in the morning or on weekends. Local hemostatic agent has been shown to be effective to stop bleeding locally on minor oral surgical procedure or tooth extraction in patients undergoing antithrombotic drug therapy alone or in combination.</p> 2020-05-15T00:00:00+07:00 Copyright (c) 2020 Dentika Dental Journal The Role of Porphyromonas gingivalis Virulence Factors in Periodontitis Immunopathogenesis 2020-04-25T13:44:47+07:00 Tienneke Riana Septiwidyati Endang Winiati Bachtiar <p><em>Porphyromonas gingivalis&nbsp;</em>is an anaerobic Gram-negative oral bacterium involved in the pathogenesis of periodontitis. Periodontitis is an infection that is characterized by damage to the supporting tissues of the teeth so that it can cause tooth loss if not given treatment. <em>P. gingivalis&nbsp;</em>locally can invade periodontal tissue and avoid host defense mechanisms. This bacterium has virulence factors which can cause deregulation of innate immune responses and inflammation in the host. The role of <em>P. gingivalis&nbsp;</em>virulence factors such as capsules, fimbriae, lipopolysaccharides, and gingipain in the pathogenesis of periodontitis will be discussed in this paper.</p> 2020-07-07T00:00:00+07:00 Copyright (c) 2020 Dentika Dental Journal
