Background: Streptococcus mutans is plaque-forming initiator bacteria. Plaque on the surface base of denture can cause color changing, bad breath, inflammation, and infection  called denture stomatitis. Denture hygiene must be maintained by denture soaking in 0.2% chlorhexidine gluconate. However, 0.2% chlorhexidine gluconatethat used incessantly can cause side effects such as the changing of denture color and the fading of denture base pigmentation. The ironwood stem bark extract can be an alternative for denture cleanser material. Objectives: To analyze the effect of ironwood stem bark extract on the growth of Streptococcus mutans on heat cured type acrylic resin denture plate. Methods: True experimental laboratories research was used with post test only control group design using 9 treatment groups which are 5%, 10%, 20%, 40%, 60%, 80%, 100% concentration of ironwood stem bark extract, 0.2% chlorhexidine gluconate and aquadest. The treatment was performed with 3 times repetition resulting in 27 total samples. Antibacterial activity was measured by calculating the bacteria colony number. Results: The 5% and 10% concentration of ironwood stem bark extract were effective in reducing Streptococcus mutans with30.3 CFU/ml and 10.3 CFU/ml average colony number. The ironwood stem bark extracts with 20%, 40%, 60%, 80%, 100% concentration are effective and equivalent to 0.2% chlorhexidine gluconate against Streptococcus mutans with 0 CFU/ml average value. Conclusion: The 20%, 40%, 60%, 80%, 100% concentration of ironwood stem bark extract is equally effective as 0.2% chlorhexidine gluconatein killing Streptococcus mutans,exhibiting potential to be an alternative for denture cleanser material.Keyword: 0.2% Chlorhexidine gluconate, ironwood stem bark extract, acrylic resin denture plate heat cured type, Streptococcus mutans.

Context: Stachytarpheta jamaicensis (L.) Vahl plant is used for traditional therapy because of its content, including flavonoids, alkaloids, tannins, saponins, terpenoids, and coumarins. Aims: To determine the antibacterial ability of S. jamaicensis roots extract (SJRE) on some selected mouth bacteria through in vitro and in silico studies. Methods: Phytochemical analysis and liquid chromatography-high resolution mass spectrometry (LC-HRMS) were done to explore the active compounds on SJRE. Absorption, distribution, metabolism, excretion and toxicity prediction, molecular docking simulation and visualization of luvangetin, and xanthyletin as anti-inflammatory and antibacterial were investigated in silico. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of SJRE against Aggregatibacter actinomycetemcomitans, Enterococcus faecalis, and Actinomyces spp. were calculated. Results: Luvangetin and xanthyletin are good candidate drug molecules with low toxicity. Xanthyletin has higher binding activity than luvangetin to TNF-α, IL-6, IL-10, peptidoglycan, flagellin, and dectin protein. SJRE exhibited a high antibacterial ability, and MIC. This extract inhibits the growth of A. actinomycetemcomitans, E. faecalis and Actinomyces spp. at various concentrations 2000, 8000, and 8000 µg/mL, respectively, with statistically significant differences (p = 0.0001; p<0.05). Conclusions: SJRE has an antibacterial ability, and 2000 µg/mL SJRE may act as an antibacterial agent in vitro. In addition, xanthyletin in SJRE has a potential role as an antibacterial and anti-inflammatory in silico.

Background: Temporomandibular disorder is a temporomandibular joint disturbance characterized with the pain in masticatory muscle and TMJ; clicking in TMJ; and deflection, deviation pattern with limitation in opening of the mouth. TMD can be found in adolescents with prevalence and severity increased along with the age. TMD in adolescent was caused by the increased of the masticatory muscle activity. In adolescent, it was caused by the increase of the emotional state especially stress. Stress is a condition that often experienced by every people including orphaned adolescent, who has more problems than the other adolescent. Purpose: The aim of this study was to analyze the correlation between stress and temporomandibular disorder in orphaned adolescent in Banjarmasin. Method: This study is an analytical observational research with cross sectional design. The study was involving 13-18 years old orphaned adolescents in Banjarmasin with purposive sampling. This study is using PSS for stress examination and RDC/TMD for TMD examination. The correlation between stress and TMD were analyzed with Spearman analysis test. Results: This research showed that 61% of the subject had moderate stress level and TMD was found in 68.3% of the subject, which consists of 58.5% had myofascial pain and 9.8% had disc displacement. Spearman analysis test showed that there is statistical correlation between stress and temporomandibular disorder in orphaned adolescent in Banjarmasin (p<0.05). Conclusion: There is a correlation between stress and temporomandibular disorder in orphaned adolescent in Banjarmasin. Keywords: Myofascial Pain, Stress, Temporomandibular disorder (TMD).

Background: Candida albicans is the main microorganism that causes denture stomatitis, thus denture soaking in cleansing solution is needed to protect them from Candida albicans contamination. The 0.2% Chlorhexidine gluconate is one of denture cleansers that induce side effects at prolonged use. An alternative ingredient that can be used as a denture cleanser is ulin stem bark extract. Objective: To determine the effect of ulin stem bark extract at 20%, 40%, 60%, 80%, 100% concentration on the growth of Candida albicans on acrylic resin denture plates. Method: True Experimental with post-test only with control group design was employed under 7 treatment groups consisting ulin stem bark extract at 20%, 40%, 60%, 80%, 100% concentration, 0.2% Chlorhexidine gluconate, and aquadest in a total of 28 samples. Acrylic resin samples that had been exposed to Candida albicans weresoaked in respective treatment for 15 minutes. Results: The average of Candida albicans colonies on acrylic resin denture plates after soaking in ulin bark extract at 20%, 40%, 60%, 80%, 100% concentration, 0.2% Chlorhexidine gluconate, and aquadest were 29.5 CFU/ml, 13.0 CFU/ml, 0 CFU/ml, 0 CFU/ml, 0 CFU/ml, 0 CFU/ml, and 155 CFU/ml. Based on Mann Whitney test, there was no significant difference when ulin stem bark extract at 60% concentration was compared to 0.2% Chlorhexidine gluoconate. Conclusion: Ulin stem bark extract at 20%, 40%, 60%, 80%, and 100% concentration have been proven to reduce Candida albicans colonies on acrylic resin denture plates, and the 60% concentration is equivalent to 0.2% Chlorhexidine gluconate.Keywords: Candida albicans,Eusideroxylon zwageri, Heat cured acrylic resin.

Background: Denture stomatitis is inflammation of the oral mucosa which supporting the denture that caused by Candida albicans. Candida albicans contamination can be prevented by immersing dentures into denture cleanser solution. One of the alternative ingredients that can be used as denture cleanser is small white ginger rhizome (Zingiber officinale var. Amarum). Objective: This study aimed to analyze whether small white ginger extract (Zingiber officinale var. Amarum) was toxic to BHK-21 fibroblast cells using the MTT assay method. Method: This study was conducted in 7 groups. Five groups consisted of extracts of 30%, 40%, 50%, 60%, 70% and 2 control groups comprised of media control and cell control. Absorbance was read using ELISA reader and cell viability was calculated. Results: The percentage of living cells of all groups of small white ginger extract treatment was 100%. The parametric analysis of One Way Annova showed p = 0.498 (p> 0.05) Conclusion: Small white ginger extract (Zingiber officinale var. Amarum) is not toxic to BHK-21 fibroblast cells using the MTT Assay method because cell viability of all concentration groups is  ≥ 60%.
