Background: Caries detector dyes are introduced to aid in identifying infected dentine. Many researchers claim that they are not specific in identifying infected dentine since dyes also stains sound tooth surfaces. The use of a dentine bonding agent could help in avoiding the penetration of caries detector dyes to some extent in less mineralized primary teeth. This study assesses caries detector dyes penetration in primary teeth with or without dentine bonding agent application. Methodology: Ninety primary extracted carious teeth were considered for the study. Teeth were divided in to two groups (45 teeth each group): group I with dye application without dentine bonding agent and group II with dye application after dentine bonding agent; in both groups three different types of dyes were used. All cavity walls and surfaces of samples in group 1 were stained with caries detector dyes for 10 s, subsequently washed with water for another 10 s and finally air-dried. A similar procedure was carried for teeth in group II after the application of a bonding agent on visibly sound tooth surfaces without the use of an etchant. Results: A statistically significant difference between two groups for staining of different tooth surfaces was noted. A Kruskal–Wallis one-way ANOVA revealed a statistically significant difference in stain removal among the different groups either by distilled water or sodium hypochlorite were observed. Conclusion: A dentine bonding agent can help in preventing caries detector dye penetration in noncarious tooth surfaces of deciduous teeth.

Background: The integration of Quick Response (QR) codes into healthcare offers a modern solution for efficient and cost-effective information dissemination. Given Saudi Arabia’s high smartphone penetration rate, QR codes hold significant potential for enhancing preventive oral healthcare. Objective: This study aims to assess the effectiveness of QR codes in providing preventive oral health information leaflets (PILs), focusing on patient awareness, ease of use, and preferences compared to traditional paper leaflets. Methods: A questionnaire-based survey was conducted among 118 participants, predominantly middle-aged and well-educated. The study assessed familiarity with QR codes, their actual usage, and patient preferences for accessing healthcare information via mobile technology or paper PILs. Chi-square tests were used to analyze the associations between demographics and preferences. Results: The study found universal awareness of QR codes among participants, with 44.1% reporting prior usage. A majority (91.5%) preferred accessing healthcare information via mobile devices, with 80.5% favoring QR codes over leaflets for their convenience and accessibility. No significant differences were observed in preferences across gender or educational levels, although women were more likely to require assistance. Participants highlighted the ease of sharing healthcare information through QR codes (87.3%). Conclusion: QR codes are widely recognized as effective tools for patient education, particularly in preventive oral healthcare. Their ease of use, accessibility, and strong preference over traditional methods underscore their potential in healthcare communication. Further research is needed to address barriers to broader adoption and assess long-term impacts.
