Comparison of a resin-based sealant with a nano-filled flowable resin composite on sealing performance of marginal defects in resin composites restorations: a 36-months clinical evaluation.

Objectives: Our goal was to evaluate the clinical behavior of resin-based composite (RBC) restorations with sealed marginal defects using nano-filled flowable RBCs (FRS) compared with resin-based sealant (RBS); this work used marginal adaptation, marginal staining, and secondary caries according to the World Dental Federation (FDI) criteria.

Materials And Methods: This was a prospective, randomized, double-blind, controlled trial. Fifty-four patients who met the inclusion criteria (older than 18 years old; with high cariogenic risk determined by Cariogram software; and restorations with marginal defects, 3 and 4 according to FDI criteria) were randomly divided into three groups.

Inflammatory markers IL-1β and RANK-L assessment after non-vital bleaching: A 3-month follow-up.

Objective: This study assessed IL-1β and RANK-L levels in vivo and color stability of non-vital teeth bleached using hydrogen (35%) and carbamide (37%) peroxides 3 months after treatment.

Materials And Methods: Fifty teeth were randomly divided into two groups(n = 25):35% hydrogen peroxide (HP) or 37% carbamide peroxide (CP). Four sessions of intracoronal walking-bleach procedure were performed.

Effects of Sealing Marginal Occlusal Defects of Composite Restorations with a Nanofiller-Reinforced Flowable Resin Composite: A Double-Blind, Randomised Clinical Trial with One-Year Follow-Up.

Purpose: To evaluate the 6-and 12-month performance of microrepairs of marginal occlusal microdefects of resin composite restorations in a group of patients with high caries risk.

Materials And Methods: Thirty-five patients with at least three resin composite restorations with marginal occlusal defects were randomly distributed into three treatment groups: (1) sealed with flowable resin composite; (2) sealed with resin-based sealant; or (3) control. Restorations in all groups were assessed using World Dental Federation (FDI) criteria at three time points: baseline, and at 6 and 12 months after sealing.

Quality of life and stability of tooth color change at three months after dental bleaching.

Purpose: Intracoronary bleaching is a minimally invasive, alternative treatment that addresses aesthetic concerns related to non-vital teeth discoloration. However, to the best of our knowledge, no studies have assessed the psychosocial impacts of such procedures on patients' aesthetic perceptions. The aim of this study was to evaluate aesthetic perceptions and the psychosocial impact of patients up to 3 months after their teeth had been bleached with hydrogen peroxide (35%) and carbamide peroxide (37%) using the walking bleach technique.

Color stability, psychosocial impact, and effect on self-perception of esthetics of tooth whitening using low-concentration (6%) hydrogen peroxide.

Objective: The aim of this study was to assess the bleaching efficacy and impact on psychosocial and esthetics self-perception of a low-concentration (6%) hydrogen peroxide (H2O2) gel compared with a conventional (37.5%) H2O2 gel when used as an in-office treatment.

Method And Materials: In total, 35 participants received two sessions of three 12-minute applications of treatment with 37.

Sealing of restorations with marginal defects does not affect their longevity.

Purpose: To evaluate sealed amalgam and resin-based composite restorations after 12 years to determine whether sealing minor defects (micro-repairs) enhanced the longevity of restorations.

Methods: 34 subjects aged 18-80 were recruited. This sample group underwent 137 restorations, including 51 resin-based composite (RC) and 86 amalgam (AM) restorations.

Long-term Performance of Refurbished Amalgam Restorations: 10-year Follow-up.

Purpose: This prospective, blinded clinical trial assessed the performance of amalgam restorations that were refurbished, replaced, or not treated.

Materials And Methods: Twenty-three patients were included, ages 18-80 years, with 63 amalgam restorations that had one or more defects in their clinical features, such as defective anatomic form, roughness and/or luster according to United State Public Health Service (USPHS) criteria. Restorations were randomly assigned to either refurbishment (A: n = 21), replacement (B: n = 21) or untreated (C: n = 21) groups.

Does refurbishing composites lead to short-term effects or long-lasting improvement?

Purpose: To evaluate the clinical performance of refurbished resin composite restorations compared to untreated (negative control) restorations over a period of 10 years.

Methods: 26 subjects (having a total of 52 composite restorations) were recruited. All restorations in the refurbished group showed clinical features rated bravo according to modified USPHS criteria.

Management of Class I and Class II Amalgam Restorations with Localized Defects: Five-Year Results.

Replacement of dental restorations has been the traditional treatment for defective restorations. This five-year prospective clinical trial evaluated amalgam restorations with localized defects that were treated by means of repair or refurbishing. Fifty-two patients (50% female and 50% male, mean age 28.
