<![CDATA[Fiber-reinforced composite (FRC) fixed dentures are exposed to various oral environments. One of the ways in maintaining good oral condition is by using mouthwash. Questions have been araised about the safety of prolongeduse of mouthwash towards FRC. The aim of this study was to evaluate the effect of immersion time in mouthwash on the flexural strength of polyethylene FRC. The specimens used were polyethylene FRC (Construct, KerrLab, USA) and flowable composite resin (Master Flow Biodinamica, Brazil). Block shaped specimens (2x2x25 mm) was light cured (n=12). Specimens were divided into threek groups of immersion: Group 1 (without immersion); Group 2 (24 hour immersion); Group 3 (48 hour immersion). The mouthwash used was Listerine Multi-Protect (Johnson & Johnson, Indonesia) (21.6% alcohol content). Flexure strength was measured by Universal Testing Machine. The results showed the average strength value (MPa) for Group 1 was 91.318 ± 12.466, Group 2 was 62.253 ± 8.027, and Group 3 was55.033 ± 3.373. Statistical analysis (ANOVA) showed that immersion time in mouthwash influenced the flexural strength of polyethylene FRC (p<0.05). LSD0.05 showed there were significant differences of flexural strength between Group1-Group 2, Group 1-Group 3 but not for Group 2-Group 3. In conclusion, the flexural strength of polyethylene FRC were decreased by the immersion time in mouthwash.]]>

<![CDATA[Infection of a surgical wound due to bacteria is a major problem for surgical patients. Cu-zeolite is a material that can suppress bacterial growth with reversible cation characteristics and adsorption to be developed into non-toxic disinfectants for humans. Packaging uses filter paper to keep disinfectant solutions or instruments that will be sterilized clean. This study aimed to observe the effects of contact time of natural Cu-zeolite on the growth of Streptococcus pyogenes (S. pyogenes) and Pseudomonas aeruginosa (P. aeruginosa) bacteria. An experimental research was simple randomized design. Cu-zeolite 10 grams were packaged in Whatman no 42 paper bags measuring 5 x 5 cm2, contacted for 15, 30 and 45 minutes in 99.5 ml of distilled water exposed to 0.5 x 108 CFU / ml of S. pyogenes and P. aeruginosa. Subsequently, bacterial growth was calculated using total plate count method. The average growth of S.pyogenes for 15, 30 and 45 minutes (1840 ± 571.236 CFU; 29 ± 16.33 CFU and 0 CFU) while P. aeruginosa was (2776 ± 725.277 CFU; 55 ± 23.214 CFU and 0 CFU) respectively. Based on the independent t-test on Cu-zeolite, the bacterial growth in the 15th and 30th minute contact between S. pyogenes and P. aeruginosa was significantly different (pth and 30th minute contact.]]>

<![CDATA[Management of mandibular fracture using open reduction Internal fixation (ORIF) method is one of the ideal treatments for single and multiple mandibular fractures. The aim of this study was to determine the quality of life of patients after the treatment of mandibular fractures with ORIF using miniplate in single and multiple mandibular fractures. This research used case-control by recalling 43 research subjects in the oral surgery department Dr Sardjito general hospital between 2013 and 2017, that consisted of patients suffering from 23 single fractures and 20 multiple mandibular fractures. Each fracture would be examined clinically and subjectively. Clinical examination parameters were conducted using the mandibular mobility index (MMI) consisting of mouth opening assessment, left and right lateral mandibular excursion, and mandibular protrusive movement. Subjective parameters were performed based on general oral health asseesment index (GOHAI) questionnaire to assess physiological aspects, psychosocial aspects, and pain. The results of the chi-square test statistic study showed that the quality of life of a patient with a single mandibular fracture was better than that of multiple mandibular fractures based on MMI and GOHAI examinations. It was concluded that patients with a single mandibular fracture had a younger age, longer time adaptation and have a better quality of life.]]>

<![CDATA[The World Health Organization reported that the SARS-CoV-2 virus has infected more than 5 million people around the world. Dental care providers and health care professionals need to be aware of the high-risk potential of crossinfection since the routes of virus transmission commonly happen through droplets and aerosols. This review aimed at collecting essential knowledge about the COVID-19 needed by dental practitioners. The review focused on the oral involvement in COVID-19, the role of oral transmission as the high-risk potential of cross-infection and recommended strategies to minimize the risk of cross-infection in dental practice. We searched all the published clinical features from PubMed, Google Scholar, Scopus and hand searched library online databases, from January 2015 until May 2020. Keywords used were “COVID-19”, “Dentistry”, “Dental protection”, “Cross-contamination”, “Aerosol and non aerosol”, and ”Povidone-iodine” with their combinations. We identified 52 articles to review after the initial selection with inclusion and exclusion criteria. Results showed use of topical applications of povidine-iodine and viricidal mouthwash could significantly reduce the high-risk of cross-infection from dentistry patients who are asymptomatic with COVID-19 infection. Further safeguards include suspending all non-emergency procedures temporarily and closely screening patients for symptoms which may be suspected to be COVID-19 infection.]]>

<![CDATA[Periodontal disease has a high prevalence in Indonesia. Gingival disease is a periodontal disease if it is severe, requires surgical therapy called a gingivectomy. Surgical periodontal procedures lead to a gingival wound that is usually treatedusing a periodontal pack. Periodontal pack has no curative property in general but assists in a wound healing process by protecting tissues. Neutrophils are inflammatory cells that act as a host’s first defense against infectious pathogens and they are important in wound healing. Wound healing can be accelerated by apitoxin gel from honeybee Apis mellifera species. The aim of this study was to determine the effectiveness of apitoxin gel on neutrophil count on gingival woundhealing process. Medical bee venom powder (Umea, Sweden) was mixed with double-distilled water to prepare a concentration of 0.01% bee venom. The solution was mixed with 10% propylene glycol, 0.01% methylparaben, and3% CMC-sodium. Thirty six gingiva of 3 month-old male Wistar rats (weighing 200-250 gram) were injured using punch biopsy (3 mm in diameter). They were treated in 4 groups: apitoxin gel, apitoxin gel with a periodontal pack, NSAIDsFlamar® gel with periodontal pack, and a periodontal pack. Three Wistar rats from each group were euthanized and their jaws were taken after 48 hours treatment to make histology slides with Hematoxylin Eosin (HE) staining. Neutrophil counts were observed. The data were analyzed using Anova test with 95% confidence level. The results showed there were significan defferebces among 4 groups (p<0.05). The highest neutrophil count on the 2nd day was found in the apitoxin gel induced the 2 day of gingival wound healing process.]]>

<![CDATA[Tooth extraction is the common procedure in dentistry. This procedure causes a wound in teeth socket. Thus, the socket had to be secured to prevent over resorption of alveolar bone. This study used the third molar as a model to examine the third molar mandibular odontectomy routine procedure in oral and maxillofacial surgery. The new bone formation could be evaluated by radiographic examination. The aim of this study was to evaluate the effect of CHA-collagen implantation on the third molar mandibular bone density using 3D-CBCT to determine bone quality. The research was conducted by comparing extraction socket after the third molar mandible odontectomy, before and after graft material implantation. The subjects were divided into two groups. Group A consisted of six non-implanted subjects and group B consisted of six subjects with CHA-collagen implanted socket. Three dimensional CBCT evaluated alveolar bone density using pixel intensity at the socket area after odontectomy procedure and 10 weeks after. The result of t-test showed that CHAcollagen implanted socket had significantly higher pixel intensity than non-implanted group (p=0,046) until 10 weeks. Spearman test showed that the implanted CHA-collagen had a positive correlation with the increase of alveolar bone density (p=0.028; r=0.860) until 10 weeks. In brief, implantation of CHA-collagen increased bone density until 10 weeks.]]>
