Objectives: The aim of this article is to assess the color stability of the bioactive restorative materials (Activa Bioactive, Beautifil II) compared with the conventional resin composite and resin-modified glass ionomer cement after immersion in different staining solutions overtime. Materials and Methods: This is an in-vitro study that investigated four different material groups: (1) bioactive composite (ACTIVA Bioactive-Restorative, Pulpdent, USA), (2) Giomer composite (Beautifil II, SHOFU Dental GmbH, Japan), (3) resin-modified glass ionomer cement (Fuji II, GC Corporation, Japan), and (4) resin composite (Filtek Z350XT, 3M ESPE, USA). One hundred samples (n=25 each group) were fabricated using a custom acrylic mold (1 mm thick × 10 mm diameter) and then immersed in five different staining solution groups: coffee, black tea, cola, mixed berry juice, and saline. Baseline (T0) shade of samples was recorded using two spectrophotometers: VITA Easyshade Digital Advance and a spectrophotometer. Then shade was recorded at the intervals of 7 (T1), 14 (T2), and 28 (T3) days of immersion. Measurements were obtained and then ΔE was calculated for each group at each time point. Three-way analysis of variance tests were used to test the interactions between different variables at the 0.05 significance level. Results: All specimens showed a significant color change (P<0.001), following 7, 14, and 28 days of storage. Activa Bioactive and Filtek Z350 showed the highest color stability overtime in different staining solutions, whereas Fuji II and Beautifil II showed the least color stability. The most significant color change was noticed in the coffee group and then in the mixed berry juice group. Conclusion: Resin-based restorative materials showed higher color stability than glass ionomer-based restorations. Both spectrophotometers gave comparable results for materials’ color stability.

Minimally invasive dentistry encourages conservative caries excavation and remineralisation of the remaining dental tissues. However, dentine remineralisation is more difficult than enamel remineralisation due to the differences in their composition. This study aims to assess the remineralisation potential of Activa BioActive-Restorative and Beautifil II restoration on demineralised dentine samples, and compares it with glass-ionomer (GIC) restoration using energy dispersive X-ray (EDX) and Knoop hardness number (KHN). Non-carious extracted molar teeth were used, a total number of ten teeth were sectioned into halves and partially demineralised using 37.0% phosphoric acid for 60 s. All samples are assessed using EDX and KHN prior to restorations. The samples are then subdivided into four groups (n = 5). Group 1 was restored with Activa BioActive-Restorative, Group 2 received Beautifil II, Group 3 was restored with GIC, and the last group was used as a negative control. After storage, the samples were analysed using EDX and KHN. The demineralisation protocol with 37.0% phosphoric acid significantly decreased the calcium:phosphate (Ca:P) ratio and KHN. Remineralisation occurred in all groups, but the highest percentage change in Ca:P ratio and KHN was observed in the Activa BioActive-Restorative group (20.7%, 82.0%, respectively), followed by the Beautifil II group, glass ionomer group, and the control group, in that order. Activa BioActive-Restorative restoration presents superior remineralisation compared to Beautifil II and glass-ionomer dental restorations.

The dental visits are a potentially valuable opportunity for screening patients with substance misuse and potentially assisting. However, it is not clear if there is a systematic approach in training general dental practitioners to gain competencies for screening and referral in such cases. We surveyed dental interns to learn about their readiness and understand their training on patients with substance misuse disorder. A 21- items questionnaire was formulated and then distributed among dental i

Background: Individuals seek out cosmetic dentists not so much for improved dental function or overall health but rather to improve the appearance of their teeth and gain more social acceptance. This study aimed to evaluate how dental students at King Abdul-Aziz University (KAU) perceived smiles based on their gender. Methods: The study included two hundred students with clinical experience from the College of Dentistry, KAU. The data were collected using a three-part validated questionnaire. The first part included socio-demographic items; the second part included two close-ended questions regarding aesthetic characteristics; and the third part consisted of perception to seventeen photos of digitally manipulated smiles to be assessed using a numeric rating scale (NRS), (1, best; 5, worst). Results: The first facial feature to catch the attention of most students was a smile, which was followed by the eyes. Almost 98% of the participants considered the smile one of the most important features of facial aesthetics. According to Faradeni research, men valued their gingival smile characteristic (p=0.013) and teeth color (p=0.001) substantially higher than women. Conversely, females had higher crucial margin discrepancy (p=0.038) and convex occlusal plane (p>0.001) than males. Conclusion: When it comes to the gingival smile, teeth color, and the initial facial feature that attracts the eye, women perceive smiles as more aesthetically pleasing than men. Gingival margin discrepancy and convex occlusal plane were more critical in males than females. Understanding smile aesthetics from the perspective of dental students enhances patient care, education, and overall treatment outcomes.

Background: Dental bleaching is a common procedure to enhance aesthetics, but it often interacts with existing composite restorations. While previous studies focused on conventional composites, it is important to evaluate the impact of bleaching on emerging bioactive composites. Aims: To investigate the color change of two bioactive resin composites compared to a conventional one and the effect of two bleaching sessions (two cycles and three cycles) on the stained composite resins. Materials and Methods: Three light-cured resin composites—Tetric N-Ceram, Shade A2, Beauty II, shade A2, and Alkasite fluoride-releasing resin (Cention N)—were used for this study. Thirty sample discs were made. CIE, L*a*b* baseline color parameters were recorded by a lab-grade desktop spectrophotometer. The samples were in blueberry juice for 12 days. Fifteen samples were thermocycle and fifteen were bleached twice, each for three cycles. We estimated color change ΔE and whiteness index WID after thermocycling (Tt), before bleaching (T0), after the first bleaching session (T1), and after the second bleaching session (T2). Data was analyzed using one-way ANOVA, post-hoc Tukey’s test, and paired t-test (P < 0.05). Results: All composites exhibited detectable color changes after staining and thermocycling, with no significant differences between materials. Bleaching led to significant changes in color and WID across all samples, with Beautifil showing the most substantial change. Moreover, the differences between the first and second bleach were not significant except for Cention N. Conclusion: The effects of staining and bleaching were similar across different resin composites, but the whiteness index indicated significant changes, particularly for Beautifil samples.

Occlusal pits and fissures remain the most vulnerable tooth surfaces for caries initiation, and selecting a sealant that seals these areas reliably is a clinically meaningful question. We investigated the internal adaptation of four pit and fissure sealants—two resin-based and two glass ionomer-based—applied to permanent premolar teeth. Forty extracted premolars were randomly assigned to four groups (n = 10): Group 1, BeautiSealant (BS); Group 2, 3M Clinpro Sealant; Group 3, GC Fuji IX without surface coating; and Group 4, GC Fuji IX with G-Coat Plus. Following 15,000 thermal cycles, internal adaptation was assessed by X-ray microtomography (micro-CT) using silver nitrate as a tracer. No statistically significant difference was found in the overall mean gap volumes between groups (p = 0.774). The 3M™ Clinpro™ Sealant group exhibited the lowest mean gap value (3.45 ± 1.71), followed by BeautiSealant (3.89 ± 1.34) and GC Fuji IX GP^® with G-Coat Plus™ (4.93 ± 4.09), whereas the GC Fuji IX GP^® without coating group showed the highest mean value (5.56 ± 5.35). Resin-based sealants achieved better fissure penetration and marginal adaptation than the glass ionomer formulations tested, though the differences did not reach statistical significance under the conditions of this study.
