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 â€œCOVID-19â€, â€œDentistryâ€, â€œDental protectionâ€, â€œCross-contaminationâ€, â€œAerosol and non aerosolâ€, and â€Povidone-iodineâ€ 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.

Specificity protein 6 (SP6) is a member of the SP/Krüppel-like transcription factor family and plays key roles in tooth development. To study its biological roles, it is important to understand the spatiotemporal regulation of Sp6 gene expression. For this purpose, we first identified two separate 5' ends of the Sp6 cDNA by 5' RACE analysis using mouse mandibular RNA. Next, we isolated mouse genomic DNA fragments covering the Sp6 gene including two putative mouse Sp6 promoter regions and generated a series of luciferase reporter constructs. We confirmed the activity of both promoters by a luciferase assay and found strong second promoter activity in dental epithelial cells. Unexpectedly, we also detected potential third promoter activity in the intron 2 of the Sp6 gene. Last, we also found that bone morphogenetic protein and wingless signals could enhance Sp6 promoter activity in dental epithelial cells, suggesting the regulatory roles of two cytokines in Sp6 gene expression during tooth development. Our findings may shed new light on the regulatory mechanisms of Sp6 gene expression and provide a possible linkage between cytokine regulation of Sp6 expression and inductive epithelial and mesenchymal interactions.

The demineralization of dental hard tissues can be caused by dental plaque. Dental plaque contains various components, especially bacteria attached to the extracellular matrix. Streptococcus mutans (S. mutans) has extracellular glucan as adhesin that is important in the attachment mechanism of tooth surface. The natural substance can be used for preventing plaque formation by inhibiting the attachment of S. mutans. Soursop plant has been used in treating various diseases. The leaves of the soursop (Annona muricata L.) are used as a material to inhibit potential attachment of bacteria S. mutans. Common surfaces that is used in adhesion testing is hydroxyapatite (HA). The aim of this study was to evaluate the effect of ethanol extract of soursop leaf (EESL) on the adhesion of S. mutans ATCC 35668 to HA discs. Soursop leaves were extracted by the maceration method using 70% ethanol. The experiment was carried out by analyzing the inhibition adhesion of S. mutans ATCC 35668 on HA discs after incubation with different concentrations of soursop leaf extract. The concentrations of extract tested were: 150; 125; 100; 75; and 50 mg/ml. Chlorhexidine 0.2% was used as a positive control while DMSO 5% was used a negative one. Data were evaluated by One Way Anova. This study statistically showed significant differences of S. mutans colony count between groups (p<0.05).The results of a post hoc Dunnett T3 test showed that the 2 highest concentrations of extract (125 and 150 mg/ml) reduced S. mutans adhesion on HA discs.The obtained results showed that ethanol extract of soursop leave inhibits the adherence of S. mutans to the HA disc.

The utilization of natural resources, one of which is plants, has been researched as an alternative to synthetic drugs because of their natural content. Potato (Solanum tuberosum L.) peels, the parts of potatoes that are often cut off and discarded, have been reported to have some phenolic compounds and flavonoids in their composition. The extract of potato peels was investigated for its analgesic, anti-inflammatory, and anti-biofilm-forming properties. A hot plate test was conducted to assess the analgesic activity in treatment doses of 50 mg/kg, 100 mg/kg, and 200 mg/kg with paracetamol as the reference drug and distilled water as the negative control, while carrageenan-induced paw edema was used to assess anti-inflammatory activity in treatment doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg with diclofenac as the reference drug and distilled water as the negative control. Anti-biofilm-forming activity was tested by using the crystal violet assay. The results showed that, compared with the negative control, treatment doses of 100 mg/kg and 200 mg/kg significantly (p < 0.05) reduced pain stimuli, whereas a treatment dose of 100 mg/kg, 200 mg/kg, and 400 mg/kg significantly (p < 0.05) reduced the edema volume increment. However, compared with the positive control, paracetamol and diclofenac were associated with the least pain stimulus and the least edema volume increment, respectively. Potato peel extract against S. mutans biofilm formation demonstrated effectiveness (p < 0.05). Based on these data, it can be concluded that potato peel extract has analgesic, anti-inflammatory, and anti-biofilm-forming activities, as demonstrated in this study.

With the ability to reduce hydrophobicity and inhibit the adhesion of S. mutans ATCC 25175 bacteria, Kulim leaf extract can be used as an alternative to chlorhexidine mouthwash in caries prevention. The objectives of this study are to determine the effect of Kulim leaf extract on hydrophobicity and adherence of the cariogenic bacteria S. mutans ATCC 25175. The test groups were divided into negative control (DMSO 2%), the treatment group (Kulim leaf extractconcentrations of 1.25%, 2.5%, 5%), and positive control (0.1% chlorhexidine). All of groups were received three replicated tests for hydrophobicity and adherence inhibition of S. mutans ATCC 25175 bacteria. The hydrophobicity test was conducted by providing 3 ml of bacterial suspension of S. mutans ATCC 25175 which had been adjusted to the McFarland 0.5 standard for each group. Furthermore, each test group was vortexed for one minute and left to stand for 15 minutes. Each treatment was tested with a wavelength spectrophotometer of 550 nm before and after the provision of 200 µl of n-hexadecane. The absorbance value on the spectrophotometer was then included in the hydrophobicity formula to determine the hydrophobicity percentage of S. mutans ATCC 25175 against n-hexadecane. To test the bacterial adhesion, the 96 wells microplate was inserted with the kulim leaf extract of each concentration,BHI-B, bacteria according to the McFarland 0.5 standard, and for the positive control and negative control. Afterwards, they were incubated at 37 °C for 24 hours before they were rinsed with distilled water, and stained with 0.1% crystal violet. Then, an optical density reading was performed using a microplate reader with a wavelength of 540 nm. The absorbance value was then included in the formula for percentage of bacterial adhesion inhibition. Post-Hoc LSD testshowed a significant difference in mean difference between the negative control group and the other treatment groups (p<0.05). In addition, it was revealed that there was no significant mean difference between treatment groups, and there was no significant difference between positive control and treatment groups of 2.5% and 5% in the hydrophobicity test. However, there was a significant difference between the positive control and the treatment group of 1.25% in the hydrophobicity test and the treatment group of 1.25%, 2.5%, and 5% in the adherence test. This study concluded that Kulim leaf extract concentration affected hydrophobicity and attachment of S. mutans ATCC 25175 with an effective concentration of 2.5%.

To evaluate the effect of eucalyptus, sappan, and cinnamon leaf and bark extract on the percentage of S. mutans biofilm formation. The test group was divided into a negative control (1% Dimethyl sulfoxide), a treatment group (eucalyptus, sappan, and cinnamon leaves and bark at concentrations of 50%, 25%, and 12.5%, respectively), and a positive control (0.2% chlorhexidine). Each concentration of eucalyptus, sappan, and cinnamon leaves and barks extract, Brain Heart Infusion Broth (BHI-B), bacteria according to the McFarland 0.5 standard, a positive control, and a negative control were added to a 96-well microplate. They were incubated at 37 °C for twenty-four hours before being rinsed with phosphate buffer saline (PBS) and stained with 0.1% crystal violet. The optical density was then measured using a microplate reader with a 540 nm wavelength. The absorbance value is then factored into the percentage of bacterial adhesion inhibition formula. A statistical test revealed a significant difference (p < 0.05) in the percentage of inhibition between the three extracts of leaves and bark and the negative control group (1% DMSO). There is a significant difference between all leaves and barks concentration and the positive control group except the 50% concentration of sappan leaf group and 50% concentration of cinnamon leaf group. The sappan leaf and cinnamon leaf at 50% concentration exhibit no significant difference (p > 0.05) with the positive control. Eucalyptus, sappan, cinnamon leaves and barks at a concentration of 50% demonstrated effectiveness of the extractant in inhibiting the formation of biofilm masses by S. mutans in comparison with the other group.
