Herbal products are gaining popularity in dental and medical practice nowadays due to their biocompatibility, higher antimicrobial activity, antioxidant and anti-inflammatory properties. Herbal medicine has experienced rapid growth in recent years due to its beneficial properties, ease of availability, and lack of side effects. As pathogenic bacteria become more resistant to antibiotics and chemotherapeutic agents, researchers are becoming more interested in alternative products and treatment choices for oral diseases. As a result, natural phytochemicals separated from plants and utilized in traditional medicine are suitable substitutes for synthetic chemicals. The aim of this review article is to list and understand several herbal alternatives that are currently accessible for use as efficient endodontic medicaments. The herbal products used in endodontics have several advantages, including safety, ease of use, increased storability, low cost, and a lack of microbial tolerance. However, preclinical and clinical testing and interactions with other materials and adverse effects are required for these herbal products.

Objective: Healthcare workers in general are at a high risk of potential infections with COVID-19, especially those who work with aerosol generating procedures. Dentists fall in this category, as not only do they operate with aerosol generating procedures but also operate within a face-to-face contact area. Methods: A structured self-administered questionnaire was developed at Najran University and provided to the participants for data collection. The data collected included information on risk perception and incorporation of measures for protection against COVID-19 to gauge the attitude of dentists during this period. Also, clinical implementation of various protective measures was reviewed. Results: Of the n = 322 dentists that answered the questions, 50% were general dentists and 28.9% were dentists working at specialist clinics, while the remaining 21.1% of dentists were employed in academic institutions. Among the newer additions to the clinic, 36.3% of dentists answered that they had added atomizers to their practices, followed by 26.4% of dentists that had incorporated the use of UV lamps for sterilization. We found that 18.9% dentists were using HEPA filters in their clinics, while 9.9% of dentists were making use of fumigation devices to control the risk of infection. One-way ANOVA was also carried out to demonstrate that there was a statistically significant difference (p = 0.049) between groups of dentists utilizing HEPA filters, UV lamps, atomizers, and fumigation devices to prevent the spread of SARS-CoV2 across their workplaces. Conclusion: Dentists are aware of recently updated knowledge about the modes of transmission of COVID-19 and the recommended infection control measures in dental settings. A better understanding of the situation and methods to prevent it will ensure that the dental community is able to provide healthcare services to patients during the pandemic.

Erosive beverages cause dissolution of natural teeth and intra-oral restorations, resulting in surface characteristic changes, particularly roughness and degradation. The purpose of this study was to evaluate the surface roughness and topography of a dental ceramic following immersion in locally available erosive solutions. A total of 160 disc specimens of a nano-fluorapatite type ceramic (12 mm diameter and 2 mm thickness) were fabricated and equally distributed into two groups (n = 80) and then evenly distributed among the following five testing groups (n = 16): lemon juice, citrate buffer solution, 4% acetic acid, soft cola drink, and distilled water which served as a control. The surface roughness (Ra) and topography were evaluated using a profilometer and scanning electron microscope at baseline, 24 h, 96 h, and 168 h respectively. Data were analyzed using ANOVA and Tukey’s multiple comparisons (p ≤ 0.05). Surface changes were observed upon exposure to all acidic beverages except distilled water. Amongst all immersion media, 4% acetic acid produced the most severe surface roughness across all time periods (i.e., baseline, 24 h, 96 h, and 168 h). A statistically significant difference in the surface roughness values between all immersion media and across all four time intervals was observed. Erosive agents had a negative effect on the surface roughness and topography of the tested ceramic. The surface roughness increased with increased storage time intervals.

Background: To accomplish the purpose of health education and health promotion programs, schools are the most effective place for delivering health information to children. The main purpose of our research was to inform, gather evidence and contribute to developing knowledge regarding the OHL, knowledge, and attitude among school teachers towards oral health in Najran region of Saudi Arabia.Methods: A questionnaire-based cross-sectional study was conducted in Najran region of Saudi Arabia for 6 months. A stratified cluster random sampling of 252 teachers was taken to represent all the teachers of Najran region of Saudi Arabia. The questionnaire contains 2 parts, sociodemographic part that include age, gender, education, teaching level, and income of the participants. The second part contains 25 items that assess the OHL (HelD-14 questions), knowledge (6 questions), and attitude (5 questions) of the participants. SPSS software version 26 was used to enter and analyze the data (IBM SPSS, Chicago, IL, USA software version 26.0). Multiple Logistic regression was applied to check the relationship between OHL and the associated factors. The Chi-square test was applied to evaluate knowledge of study participants. The level of significance was set up at p < 0.05.Results: A total of 252 school teachers with a Mean age of school teachers 32.25 ± 8.46 participated in the study. The multiple logistic regression model shows the association between age, education, and OHL level of school teachers. After adjustment for sociodemographic factors age (OR = 0.219, 95% CI: 0.058–0.834), education (OR = 9.053, 95% CI: 1.135–72,023) were significantly associated with OHL of school teachers. Female participants showed better performance with respect to all the knowledge questions, a significantly higher level of knowledge (p-value < 0.05) was reported with all the questions except the second question (dental plaques causes). 94.8% of teachers agreed that children’s teeth should be checked by a dentist on a regular basis, while 96.8% agreed that dental health education should be included in the primary school curriculum and that all teachers should receive dental health education training.Conclusion: Overall, school teachers have high oral health literacy, adequate knowledge, and a positive attitude toward oral health. The female teachers had more knowledge about dentistry than their male counterparts.

Background: Root canal sealers and repair materials should have the desirable physical, chemical, and biological characteristics, and an antibacterial effect if possible. There is little information available on the biocompatibility of new sealers on the market. Fourier transform infrared spectroscopy (FTIR) can offer trustworthy data to examine chemical structures; another technique for revealing the elements in the constituents that may contribute to the cytotoxicity of these sealers is scanning electron microscopy (SEM), with the goal of elemental mapping utilizing energy-dispersive X-ray spectroscopy (EDX). Methodology: All the root canal sealers were mixed as per the manufacturers’ instructions and allowed to set in molds for 24 h. Then, the samples were placed into an incubator (Memmert GmbH + Co. KG, Schwabach, Germany for 72 h, in a moist environment to allow complete chemical setting of the sealers. The organic and inorganic components of the sample were identified using FTIR with the wavelength length in the infra-red region measuring 400–450 nm. The finely crushed samples were coated with gold metal; following that, the sealer samples were examined under a scanning electron microscope (SEM) at 5000×, 10,000×, and 20,000× magnification, followed by energy-dispersive X-ray spectroscopy. Results: The surfaces of BioRoot and DiaRoot sealers revealed a relatively uniform distribution of irregular micro-sized particles aggregated in clusters, with the particle size ranging from 1 to 65 µm and 0.4 to 55 µm, respectively. OneFill, iRoot, and CeraSeal demonstrated irregularly shaped particles with particle sizes of 0.5 to 105 µm, 0.5 to 195 µm, and 0.3 to 68 µm, respectively. The EDX microanalysis revealed that oxygen, calcium, and carbon were found in all the tested sealer materials. Silicone and zirconium were absent in DiaRoot, but DiaRoot contained fluoride and ytterbium. Moreover, aluminum was noted in DiaRoot, One Fill, and CeraSeal, and chloride was only observed in BioRoot. FTIR analysis revealed strong absorption bands at 666 cm⁻¹ and 709 cm⁻¹ in BioRoot. Bands at 739 cm⁻¹, 804 cm⁻¹, 863 cm⁻¹, 898 cm⁻¹, and 1455 cm⁻¹ were observed in DiaRoot. Bands at 736 cm⁻¹ and 873 cm⁻¹ in OneFill suggested the presence of C-H bending. Similarly, bands were observed at 937 cm⁻¹, 885 cm⁻¹, 743 cm⁻¹, and 1455 cm⁻¹ in iRoot, representing C-H stretching. Conclusions: All root canal sealers had diverse surface morphologies that contained irregular, micro-sized particles that were uniformly distributed, and they lacked heavy metals. All the experimental sealers comprised mainly calcium, oxygen, and carbon.

Background: In the past couple of years, the use of social media has been on a tremendous rise with greater attention in the field of healthcare, including dentistry. The use of social media for professional purposes is emphasized as unprofessional use can be detrimental. This study aims to evaluate the use of social media by dentists for professional purposes. Materials and Methods: This cross-sectional study was carried out between December 2021 and March 2022. An online questionnaire was formulated using Google Forms and distributed to the dental professionals through various social media platforms such as Twitter©, Facebook©, Instagram©, Snapchat©, WhatsApp©, and Email©. The questionnaire consisted of two parts: demographic characteristics and questions about the use of social media for professional purposes. For data analysis, SPSS version 25.0 was used, where a multiple linear regression test was used to compare the responses of the participants with their demographic characteristics. A p-value of ≤ 0.05 was considered to be statistically significant. Results: A total of 404 dentists participated in this study with a response rate of 89.7%. The majority of the 276 (68.3%) dentists believed to have a professional account to use social media for professional purposes. Most of the 280 (69.3%) dentists agreed social media improved knowledge and communication skills with the patients. About 248 (61.4%) dentists considered the use of social media for general purposes during clinical hours led to wastage of time. About 160 (39.6%) dentists considered connecting with patients on social media to be inappropriate. Conclusion: The use of social media is on the rise at a tremendous rate in different fields of work, including dentistry. Social media is a great tool for dentists to help expand and grow their clinical practice. However, the professional use and ethics whilst using social media should be considered by the dentists.
