Bone metabolism requires a balance mechanism between intricate processes of bone formation and resorption, which is affected by the essential interaction between osteoblasts and osteoclasts. Interleukin-17 (IL-17) is a family of cytokines consisting of six isoforms: IL-17A, IL-17B, IL-17C, IL-17D, IL-17E, and IL-17F. Among these isoforms, IL-17A has shown promising and novel roles in the regulation of bone metabolism. IL-17A has also captivated the interest of many researchers since its discovery because of its role as a pro-inflammatory cytokine which mediates a few inflammatory processes. This review describes the biology of IL-17A and its receptor as well as summarises the regulatory role of IL-17A in bone metabolism and diseases through some known pathways. Understanding the function of IL-17A in bone metabolism may lead to the development of therapeutics or diagnostic strategies for some bone diseases; as well as future therapy using tissue engineering and regenerative medicine approaches.

Aims: The effect of Quercus infectoria (QI) gall extract on the fungal expression of antioxidant defense enzymes of Candida albicans was studied in an effort to unravel its anti-fungal mechanism. Methodology and results: Minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC), and time kill assays were conducted to analyse the antifungal activity of the extract against C. albicans. Total protein profiles of C. albicans were determined by SDS-PAGE and real-time PCR was used to quantify the genes expression level of superoxide dismutase (SOD1), catalase (CAT1) and glutathione peroxidase (GPX3) following treatment with aqueous QI gall extract. The MIC and MFC values of the extract against C. albicans were 8 mg/mL and 16 mg/mL respectively. Fungistatic and fungicidal activities of the extract were observed after 24 h at 1× MIC and 2× MIC from the time-kill assay. A lower total protein bands density of extract-treated C. albicans was visualized when compared to the untreated cells at concentrations of 1× MIC and 2× MIC. A significant reduction in the expression of GPX3 (p 0.05). Conclusion, significance and impact of study In conclusion, QI gall extract exerted an anti-Candida activity and it is apparently effective in downregulating the gene expression of GPX3 in C. albicans. Of note, the present findings elucidated a preliminary mechanism associated with the organism’s survival resilience which represents a key target for the development of anti-Candida agents in future.

This review paper aims to present the evolution in methods of delivering oral hygiene information to orthodontic patients. Orthodontic fixed appliance treatment confers numerous benefits to patients in terms of occlusion, function and aesthetics, but it is associated with unwanted consequences due to challenges in maintaining oral hygiene. The ways of delivering oral hygiene information to patients have progressed over the years. Recent years have seen an increase in the popularity of incorporating technology in delivering oral hygiene information and monitoring of oral hygiene practices. The use of video-based instructions to web-based platforms such as Massive Open Online Course (MOOC) and social media platforms such as YouTube, Instagram and TikTok have all become a mode of oral hygiene information conveyance. Mobile apps are now a popular means to keep track of oral care practices such as toothbrushing frequency. The active ingredients of oral care products have improved providing a greater anticariogenic and antiplaque effect to the user as have the design of toothbrushes and even dental floss. In the future, more advanced technology may be used, such as artificial intelligence (AI) and machine learning, to create intelligent machines that can help educate patients on oral health maintenance and improvement.

Introduction: Delivering oral hygiene instruction is one of the integral parts of orthodontic treatment. However, there is scarce information regarding the impact of audiovisual method on knowledge retention among orthodontic patients. This study aimed to assess knowledge retention of the patient after instruction delivered in audiovisual (AV) method and compare it to the standard written and verbal (WV) method. Methods: This prospective clinical trial was conducted on 60 patients aged 13 to 40 years. They were randomized into the audiovisual group (n=30) and written & verbal group (n=30). Patients’ knowledge retention was measured using a self-administered questionnaire in Google form, immediately after instruction given as short-term retention and long-term retention for three timepoint, i.e., 1-month, 3-month, and 6-month. Results: There was a significant improvement in knowledge for both AV and WV methods at immediate and 1-month assessment and the knowledge retained until 6-month follow up. The AV method demonstrated a significantly higher increase in knowledge retention at immediate and 1-month than the WV method. Conclusion: The AV method was significantly more effective in improving patient's knowledge retention compared to the written & verbal methods. Repetition of instruction also influence the retention of knowledge.
