Introduction: Intraoral photography is crucial in dentistry for documentation, communication and education. Contrasters play a pivotal role, influencing patient experience and image quality. Traditional metal contrasters have limitations regarding patient friendliness and procedural compatibility. Aim: To assess ease and comfort among patients and operators and to compare the contrasting ability of commercially available contrasters with newly designed contrasters in intraoral photography. Materials and Methods: A single-blinded, cross-sectional analytical study was conducted in the Department of Conservative and Endodontics and the Department of Orthodontics, KM Shah Dental College and Hospital, Vadodara, Gujarat, India, from January 2024 to February 2024. After obtaining ethical approval, 50 patients with no pain, swelling, or discomfort in the maxillary anterior region, as well as, only those operators trained in intraoral Digital Single-lens Reflex (DSLR) photography, were enrolled. Following randomisation and standard camera settings, intraoral images were captured by 50 operators using both conventional metal and newly designed 3D-printed contrasters.

Introduction: Chlorhexidine is commonly used to treat dental diseases as a broad-spectrum topical antibacterial medication. Povidone-iodine is a water soluble blend of molecular iodine and the solubiliser polyvinyl pyrrolidone. Amsarveda (pharmaceutical company) developed a natural mouth sanitiser with liposomal curcumin. Aim: Comparative evaluation of the effect of chlorhexidine mouthwash, povidone-iodine gargle and herbal mouth sanitiser on colour stability and surface roughness of conventional nanohybrid composite. Materials and Methods: This in-vitro study was conducted in the Department of Conservative Dentistry and Endodontics at KM Shah Dental College and Hospital, Vadodara, Gujarat, India, from November 2020 to June 2021. Total 60 extracted human permanent maxillary premolar teeth were selected. Class V restorations were performed on the extracted teeth with nanohybrid composite resin. The samples were divided into three groups by computer randomisation. The three test solution groups (n=20 each) ie., group A-chlorhexidine 0.2% mouthwash, group B has povidone-iodine (2%), group C-herbal mouth sanitiser. The colour change and surface roughness of all the samples were measured before and 15 days after immersion into the test solutions. The data was collected and statistically analysed using one-way Analysis of Variance (ANOVA) and Tukey's post-hoc test. Results: The E values for all three groups show a statistically significant difference (p-value <0.001). The mean baseline and after 15 days values for surface roughness in groups A and B showed a statistically significant difference (p-value <0.001). Whereas, no statistically significant difference in group C (p-value=0.654). Conclusion: Based on the results of the present study, it can be stated that the povidone-iodine gargle showed more surface roughness and colour change of conventional nanohybrid composite followed by chlorhexidine mouthwash and herbal mouth sanitiser.
