Vitamin D, a steroid hormone primarily acquired through diet, supplements, and sunlight exposure, is crucial for maintaining calcium phosphate balance and bone turnover, thus supporting the musculoskeletal system. In addition, it plays an important role in the immune system's function. This review aimed to investigate the effects of vitamin D deficiency on the oral cavity, jaw, and facial structures. A comprehensive search was conducted on studies published in English from 2010 to 2024 acros

Sodium hypochlorite (NaOCl) is considered the most effective solution for irrigating root canals due to its powerful disinfecting properties, including its ability to dissolve tissue, disrupt microorganisms, and eliminate bacterial biofilms in endodontic treatments. Typically, NaOCl is used at concentrations ranging from 0.5% to 5.25% during procedures. The objective of this research was to evaluate the bactericidal effects of different concentrations of NaOCl on biofilms and their influence on

Dental caries, as reported by the World Health Organization, affects about 60-90% of school-aged children and almost all adults worldwide. Early detection of micro-damage to tooth enamel has become an important issue in modern dentistry. Laser-induced fluorescence (LIF) diagnostics offers a promising solution by detecting caries through the analysis of the intrinsic fluorescence of microorganisms. This study presents a method for LIF detection of enamel micro-damage using a model mixture contain

This study aimed to investigate the maturity of enamel in permanent teeth and investigate the trace element composition in its surface layers through elemental dispersion spectral analysis. This research focused on third molars from individuals aged 16 to 18 years, specifically 51 intact molars that had not yet erupted but were in the root development phase. The atomic chemical analysis of tooth enamel showed that oxygen, chlorine, sodium, calcium, and phosphorus were found in all the samples. I

This prospective study investigated the frequency and severity of bleeding during and after tooth extractions in patients taking direct oral anticoagulants (DOACs). Patients requiring at least one extraction were enrolled, with their DOAC therapy either continued or temporarily paused. Participants were grouped according to the number of teeth removed (≤3 or >3), the use of flap elevation, and whether osteotomy was performed. Bleeding was monitored during the procedure, at 20, 40, 60, and 80 min

Titanium implants have long been established as reliable in dental implantology; however, zirconia implants are now being explored as a metal-free substitute. This investigation assessed how zirconia implant macrodesign and bone density influence initial implant stability. Two zirconia systems—Neodent® Zi Ceramic and Straumann® PURE Ceramic—were evaluated using polyurethane blocks simulating varying bone densities (10, 15, 20, 30, and 40 PCF). Each implant type underwent repeated insertion and r

Prolonged use of manual dental instruments often contributes to operator discomfort, muscle fatigue, and work-related musculoskeletal disorders (MSDs). This pilot in vivo investigation explored how an innovative ergonomic handle sheath affects muscle activity, perceived comfort, and fatigue during two common dental procedures: (a) ultrasonic scaling performed by hygienists with and without MSDs, and (b) tooth cavity preparation performed by dentists using a micromotor handpiece. Twenty dental hy

This in vitro investigation explored the protective potential of high-concentration fluoride and remineralizing agents (F-APC) against dental erosion in the context of competitive swimming. Forty-eight extracted teeth were collected, stored in saline, and assigned to three experimental conditions. In the control group (G1), teeth were half-submerged in chlorinated pool water. In the fluoride group (G2), teeth were fully immersed in chlorinated water, with one half of each tooth surface treated o

This in vitro investigation evaluated how various primers influence the shear bond strength (SBS) and adhesive remnant index (ARI) of orthodontic brackets attached to a reinforced polyetheretherketone (PEEK) substrate. Forty samples were randomly divided into two groups based on the primer used during orthodontic bonding: Group 1 (control)—Transbond XT adhesive with Visio.link primer, and Group 2 (experimental)—Transbond XT adhesive with a conventional orthodontic primer. Following bonding, spec

The global occurrence of obstructive sleep apnea (OSA) highlights the demand for effective management strategies. Mandibular advancement devices (MADs) have proven to be a reliable intervention for mild to moderate OSA, despite their potential to cause dental changes. This research examined the characteristics, onset, and persistence of such dental alterations. In the prospective cohort (n = 12), dental impressions were recorded before MAD insertion and subsequently after three, six, nine, and t

In previous decades, root canal shaping was primarily achieved with manual stainless steel files. The development of nickel–titanium (NiTi) mechanical instruments has since offered the potential for more efficient and predictable canal preparation. Despite these advancements, the use of NiTi systems in undergraduate training remains limited. This study aimed to compare three root canal preparation approaches—manual instrumentation using stainless steel hand files, continuous rotary motion with P
