Article Abstract
Objective: We investigated the potential association between intraoral metal alloys and the presence of in patients with rheumatoid arthritis (RA).
Methods: A case-control study was conducted using bacteriological tests. The RA group included 80 patients, of whom 40 tested positive for and 40 tested negative. The control group consisted of 81 subjects without RA, with 39 testing positive for and 42 testing negative.
Results: Univariate analysis identified the presence of intraoral metal alloys (lingual fixed retainers or metal-ceramic crowns), male sex, and gingival inflammation as significant predictors of Prevotella Intermedia presence ( < 0.05). In multivariate analysis, intraoral metal alloys demonstrated the strongest association, with an odds ratio = 4.21 ( < 0.001). However, no significant difference in positivity was observed between the RA and control groups.
Conclusions: These findings suggest that intraoral metal alloys are associated with an increased prevalence of in subgingival pockets among adults, independent of RA status.

This study explored a novel digital design and fabrication method for a double constrained split orthodontic miniscrew guide to improve the accuracy and safety of clinical miniscrew implantation and reduce related complications. A patient requiring miniscrew implantation was selected, and data were acquired using cone beam computed tomography (CBCT) and intraoral optical scanning. For the construction of a double constrained split guide including a screw-hole guide and an insertion rod guide, different types of software such as Mimics 24.

Introduction: Soft tissue thickness may play a role in the success of dental implants by influencing factors such as bone health and implant stability. This study aimed to evaluate the effect of mucosal thickness on crestal bone levels and implant stability in patients with platform-switched abutments. The objectives were to measure bleeding on probing (BOP), implant stability, and changes in crestal bone levels in thin and thick mucosal environments over six months post-prosthetic loading.

Statement Of Problem: Virtual implant positioning allows greater predictability in oral rehabilitation. Edentulous arch images can be matched in a planning software program by aligning fiducial markers, a procedure known as image registration. Among the steps involved in guided implant surgery, registration may contribute to deviations, leading to the mispositioning of implants and further adverse clinical outcomes.

Purpose: To evaluate the effect of different decontamination protocols on the bonding strength of MDP-containing resin cement to saliva-contaminated zirconia ceramic.
Methods: 144 zirconia samples (12 mmx12 mmx1.2 mm) were prepared from 4Y-TZP and 6Y-TZP blocks, sandblasted with 50 μm Al₂O₃, and contaminated with artificial saliva.

Background: The development of nanoparticles offers promising potential for improving biofilm management; however, the biofilm itself acts as a diffusion barrier, limiting effective treatment. This study aimed to investigate the adsorption and diffusion of nanoparticles in an intraorally formed biofilm.
Methods: Bovine enamel specimens (n = 24) were mounted on customized maxillary splints and worn intraorally by two subjects for 24 h to allow biofilm formation.
