Color Stability of Bulk-Fill Flowable Resin Composites After Artificial Aging.

Background: This study aimed to evaluate the color stability of bulk-fill flowable resin composites with 2 difference shades at baseline and after artificial aging.

Methods: Disk-shaped specimens (Ø10 × 4 mm) were fabricated from three bulk-fill flowable resin resin composites (Filtek Bulk-Fill Flow, Venus Bulk-Fill Flow, and Estelite Bulk-Fill Flow). The specimens in each bulk-fill resin composite group were divided into two subgroups (n = 10 per subgroup) with two different shades, A1 (N = 30) and A3 (N = 30), and were polymerized with light curing (800 mW/cm/Valo LED Unit, Ultradent) and polished.

Navigating Esthetic Challenges: Immediate Implant Placement and Comprehensive Restorative Solutions-A Clinical Case With 2-Year Follow-Up Study.

The esthetics of immediate implant dentistry can be challenging. Clinical considerations for immediate implant placement have demonstrated long-term success rates comparable to traditional delayed implant protocols. However, it is a sensitive technique that requires proper treatment planning as well as meticulous execution to be predictable and successful in the long term.

Purpose: This systematic review and meta-analysis aimed to evaluate the depth distortion and angular deviation of fully-guided tooth-supported static surgical guides (FTSG) in partially edentulous arches compared to partially guided surgical guides or freehand.

Material And Methods: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered in the Open Science Framework (OSF). The formulated population, intervention, comparison, and outcome (PICO) question was: "In partially edentulous arches, what are the depth distortion and angular deviation of FTSG compared to partially guided surgical guides or freehand?" The search strategy involved four main electronic databases, and an additional manual search was completed in November 2023 by following an established search strategy.

Minimally invasive techniques in the management of muscular temporomandibular joint disorders: A five-year observational study.

Background: To evaluate the effectiveness of three minimally invasive techniques for managing patients with myofascial pain dysfunction, determine their association with sociodemographic factors, habits, medication usage, comorbidities, treatment history, pain duration, complaint intensity, and diagnosis limitations.

Material And Methods: This five-year observational study scrutinized 1,000 medical records from individuals treated at the TMD Orofacial Dental Research Center. TMD treatments were organized into Group 1 (thermotherapy, exercises, and CBT), Group 2 (Group 1 plus intramuscular manual therapy), and Group 3 (Group 1 and Group 2 plus occlusal appliances) and correlated with sociodemographic factors, habits, prior medication usage, comorbidities, history of prior treatments, duration of pain, intensity of complaint, and diagnosis limitations or without limitations regarding the symptoms of muscular temporomandibular disorders (TMD).

Drafting strategic plans for dental school departments traditionally involves a committee-led or leadership-driven process, often overlooking input from the majority of departmental members. In this manuscript, the authors advocate for a novel approach wherein departmental activities undergo comprehensive review and analysis, and the establishment of novel objectives through diverse forums of engagement with both faculty and staff, conducted collectively and individually over a concise time limit. This methodology endeavors to solicit input from all departmental constituents through varied channels, fostering an environment wherein all members feel empowered to express their viewpoints, resulting in a strategic plan that resonates with the entire department and enhances the likelihood of successful implementation.

Single administration of a psychedelic [(R)-DOI] influences coping strategies to an escapable social stress.

Psychedelic compounds have potentially rapid, long-lasting anxiolytic, antidepressive and anti-inflammatory effects. We investigated whether the psychedelic compound (R)-2,5-dimethoxy-4-iodoamphetamine [(R)-DOI], a selective 5-HT receptor partial agonist, decreases stress-related behavior in male mice exposed to repeated social aggression. Additionally, we explored the likelihood that these behavioral changes are related to anti-inflammatory properties of [(R)-DOI].
