- Aesthetic preference in the transverse orientation of the occlusal plane in rehabilitation: perspective of Laypeople and dentistsPublication . Carvalho, Ana Lidia; Daniela Gavinha Da Costa, Liliana; Martins, Joana Meneses; Manso, M. Conceição; Gavinha, Sandra; Herrero-Climent, Mariano; Ríos-Carrasco, Blanca; Falcão, Carlos; Ribeiro, PauloThe present study had a convenience sample with 236 laypeople and 242 dentists who completed an online questionnaire to choose the most attractive image among six pairs for comparison. Control image: symmetric (parallelism between occlusal plane (OP), commissural line (CL), and interpupillary line (IL)). Change of Control, obtaining three images with a 3-degree inclination of the labial commissures. Image A: OP parallel to IL; Image B: OP parallel to CL; Image C: OP at 1.5 degree mean angulation between IL and CL. Non-parametric comparison (IBM© SPSS Statistics vs. 27.0, p < 0.05). The “Dentists” group’s decreasing order of preference (attractiveness) of the images is: Control > A > C > B (p < 0.05). In the “Lay” group, it is: Control > A > (C not ≠ B). Dentists significantly prefer more the Control and Image A than laypeople (p < 0.001). Sex (single exception in laypeople), age, and dentist’s area of activity did not interfere in the perception of attractiveness. Dentists and laypeople preferred the Control when compared to images with CL canted. In the existence of CL inclination, the preference of the groups was the IL as a reference for OP orientation, with the mean angulation or coincident with the CL being considered less aesthetic.
- Universal adhesive brands functional performance and survival: 18th-48th months systematic report (Poster P112)Publication . Manarte-Monteiro, Patricia; D’Elia, Leonardo; Gavinha, Sandra; Daniela Gavinha da Costa, Liliana; Pereira da Silva, LigiaAims: This poster aims to compare retention rates of Universal Adhesive (UA) Brands in non-carious cervical lesions (NCCL) restorations and, to evaluate their functional survival by adhesion modes, Etch-and- Rinse (ER), Self-Etch (SE) and Selective Enamel Etching (SEE). Material & methods: A Systematic search was performed in PubMed, Web-of-Science and B-on for randomized clinical trials (RCTs) published between 2015-2025. Results: Of 251 screened records, 21 RCTs were eligible, comprising 16 UA brands with overall similar retention rates (p>0.05), median follow-up of 24-month (IQR 24-36 months). Conclusions: UA brands applied by ER and SEE adhesion modes confirmed a decisive impact on long-term retention though, no UA brand can yet be considered as gold-standard for retention survival over 18th-48th month.
