A multidisciplinary approach and minimally invasive therapies are essentials to obtain effective results from aesthetic dentistry. Minimally invasive dentistry requires minimal intervention for the placement and replacement of restorations. This paper reports a case of 24-year-old female, who was dissatisfied with her dark and unsatisfactory dental restorations. After the clinical examination, it was proposed to perform a gingivoplasty, tooth bleaching and replacement of the unsatisfactory restorations with resin composite. Initially, the gingivoplasty was performed, which consisted of the following steps- periodontal probing, measurement of new zeniths and marking of bleeding points, internal bevelled incision and removal of the gingival collar with periodontal curettes. After healing period, using the combined technique, in-office bleaching was done with 35% hydrogen peroxide followed by three weeks at-home bleaching with 16% carbamide peroxide. The unsatisfactory restorations were replaced with resin composite according to dental substrate. Sequentially, occlusal adjustment, finishing and polishing with sanding discs and felt discs were performed. The multidisciplinary approach in the execution of the treatment was fundamental for the aesthetic harmonisation of the smile, providing health, well-being of the patient and professional satisfaction.

Introduction: Restorations with high surface roughness directly influences restorative procedure longevity. When used correctly, polishing systems optimizes the quality, aesthetics and longevity of composite resins. Aim: To evaluate the influence of three two-step polishing systems of spiral rubber discs on surface roughness of three different bulks fill composite resins. Materials and Methods: This in-vitro study was conducted from May, 2021 to January 2022, at the Universidade Estadual de Pernambuco, School of Dentistry, Recife, Pernambuco, Brazil. Total 20 specimens of each resin {three Bulk Fill resins: Filtek One Bulk Fill (3M-ESPE), Aura Ultra Universal Restorative Bulk Fill (SDI) and Opus Bulk Fill (FGM)} were randomly divided into four groups (n=5 each). The three groups include test polishing systems {Sof-Lex Diamond Polishing System (3M/ ESPE, Saint Paul, Minnesota, USA), Decamp Plus Twist Spiral EVE (Odon omega, Ribera Prato, SP, Brazil), Spiral Swivel (Jota, Ruth, Kanton St. Gallen, Switzerland)} and one control group include no polishing system. To assess surface roughness, before and after polishing, specimens were evaluated on a digital rugosimeter. Data was subjected to the Shapiro-Wilk test to assess normality, followed by Analysis of Variance (ANOVA) to compare the mean between the different types of resins and types of polishers. Results: For the composite resins studied, significant differences were observed only when polished with Soflex Spiral (p-value=0.013). All polishing system caused a significant improvement in the roughness of composite resins compared to the control group. The mean roughness reduction comparison test between the types of polisher was significant (p-value <0.001), there was a significantly greater reduction in the roughness of EVE Decamp Plus Twist Spiral and Swivel Spiral polish system, compared to polish system from Sof-Lex Diamond Polishing System and control group. No statistically significant differences were found between EVE Diacomp Plus Spiral and Spiral Swivel polishing system. Conclusion: The spiral rubber polishers evaluated were effective in reducing the roughness of bulk fill composites. However, EVE Decamp Plus Spiral and Spiral Swivel polishers showed better results than Sof-Lex Spiral.
