The aim of this study was to evaluate the marginal integrity of an alkasite restoration in comparison to that of a conventional composite resin restoration following intra-coronal bleaching with 30% hydrogen peroxide (HP) containing sweet potato extract (SPE) as an additive. Access cavities were prepared in 60 extracted human incisors. The teeth were decoronated 2mm below the CEJ and the pulp chambers were sealed cervically. The samples were divided into two groups (n = 30) based on the type of restorative material - group I: Hybrid composite resin and group II: Alkasite restorative material. Both the groups were divided into three subgroups (n = 10) based on the intra-coronal bleaching agent used namely, subgroup A: no bleaching (NB); subgroup B: 30% hydrogen peroxide (HP) and subgroup C: 30% hydrogen peroxide containing SPE (HSP). The tooth-restorative interface was observed under a scanning electron microscope (SEM) to determine the marginal integrity. The results were tabulated and statistically analyzed using one-way ANOVA. Specimens bleached with HP alone showed higher marginal gaps, irrespective of the restorative material used. Subgroups A and C showed lesser marginal gaps under both the restorative materials. An improved marginal integrity was seen with the alkasite material. It can be concluded that the addition of SPE to HP improves the marginal integrity of the coronal restorative material placed immediately post-bleaching. The new alkasite material holds promise as a permanent coronal seal in cases of intra-coronal bleaching.

Background: Minimally invasive dentistry is now becoming the forefront of restorative dentistry, involving less traumatic treatment protocols, conservation of tooth structure and surrounding tissues, enhancing the long-term survivability of treated teeth, and improving the overall quality of life for patients.
Objective: The current case report was conducted to evaluate acquiring deep subgingival interproximal carious lesions by the mean of thermacut bur gingivectomy, in terms of patient satisfaction through pain evaluation, Bleeding on Probing, Pocket Depth, Crestal Bone Level evaluation, and restoration evaluation using modified USPHS criteria.
Material And Methods: A patient with a deep proximal cavity in the posterior tooth was thoroughly examined and underwent Thermacut Bur Gingivectomy (TBG) after caries removal followed by direct resin composite restoration of the prepared cavity.

In terms of rotator cuff repair, there is a goal for complete repair and healing, as rotator cuff integrity correlates with clinical and functional results. Retear has been shown to have a significant influence on progression toward osteoarthritis, and patients with an intact supraspinatus show superior abduction and flexion strength. However, in cases where complete repair may not be possible and/or cost limitations may prohibit augmentation, partial repair can provide a respectable outcome.

Purpose: This study aimed to investigate the effect of crystallization and finish line curvature on the integrity of lithium disilicate crowns fabricated by using partially crystallized (P) and fully crystallized (F) blocks.
Materials And Methods: Forty-eight lithium disilicate crowns were fabricated based on the designated lithium disilicate blocks and finish line curvatures. The specimens were divided into four groups (n = 12 each): P block with a curved finish line (PC), P block with a straight finish line (PS), F block with a curved finish line (FC), and F block with a straight finish line (FS).

Background: Long-term durability of a restoration relies on the marginal integrity and its ability to withstand the occlusal forces. Fiber-reinforced composites (FRCs) exhibited superior properties in terms of fracture toughness, flexural strength, and wear resistance.
Aim: The aim of this study was to assess and compare marginal adaptation and microtensile bond strength (µTBS) of posterior FRCs comparing with a condensable composite.

V-to-Y advancement flap is a successful repair technique that preserves vascular and tissue integrity adopted after Mohs micrographic surgery to repair cutaneous defects on the head and neck. However, defects at the lateral distal nasal ala requires large extension beyond cosmetic margins that increase risk of skin webbing, an undesired result on a cosmetically sensitive location to the patient. In this article, we present a novel approach to modifying the procedure employing the V-to-Y advancement flap by truncated the trailing end of the island pedicle to allow for successful healing and better patient satisfaction.
