Background: The dimension of attached gingiva is a very important landmark in the periodontal health, and determine the function of the mucogingival unit, the progression of marginal inflammation and also affects aesthetic dentistry, orthodontics and implantology. The determination of gingival/periodontal biotype is important in dental/periodontal practice. Hence, the aim of this cross sectional clinical study was to assess the width and thickness of attached gingiva in young, periodontally healthy individuals and to provide anthropometric data in Hungary.
Materials And Methods: 68 periodontally healthy (between the age of 14-28) individuals participated in the study. The thickness of the gingiva was determined using transgingival transparency of periodontal probe at each tooth in the maxillary and mandibular dental arch. Based on this non-invasive technique three biotype categories were determined i.e. thin > 1 mm, medium 1-2 mm and thick < 2 mm. The width of the gingiva was assessed by William's graduated probe measuring the distance between the gingival margin and mucogingival line the midline of each tooth. The data were statistically analyzed and compared according to gender, dental arch and group of teeth.
Results: The gingiva was found to be thinner in females than males. The thin biotype was significantly more common among females while in males the thick biotype was the dominant. The individual variations were common within dental arch and many times the biotype switched from tooth to tooth. The average width of the attached gingiva was wider in the maxilla than in the mandible and there was no statistically significant correlation between the biotype and the width of attached gingiva. Manifest gingival recession occurred just around teeth with thin biotype.
Conclusion: In the present study, we concluded that gingival thickness and width varies with gender and dental arch location and the biotype had no effect on the width of attached gingiva.

Oral melanocytic nevi (OMN) are rare benign tumors originating from melanocytes with an unclear pathogenesis. The current theory suggests that OMN originate from dormant dendritic melanocytes that become enclosed in the dermis during the embryonic migration of melanoblasts - the precursors of melanocytes - from the neural crest to the epidermis. OMN can be congenital or acquired, with acquired nevi being more common.

Objectives: The current literature about the effect of advanced platelet rich fibrin(A-PRF) with vestibular incision subperiosteal tunnel access (VISTA) technique in treating gingival recession is scarce. Therefore, the aim of the current randomized clinical trial is to evaluate the effect of A-PRF with VISTA technique in the treatment of Cairo class 1 gingival recession (RT1).
Methods: Twenty-four patients who met the eligibility criteria were randomly allocated into two groups.

Statement Of Problem: Acrylic denture base resins are subject to colonization by oral and nonoral bacteria, contributing to the onset of denture stomatitis. However, how the addition of antimicrobial substances affects the mechanical and optical properties of additively manufactured denture base resin remains unclear.
Purpose: The purpose of this in vitro study was to investigate the surface roughness, color stainability, and flexural strength of antimicrobial-modified, additively manufactured polymethyl methacrylate (PMMA) denture base resin in tooth and gingiva colors.

Background: Periodontitis and diabetes are chronic diseases where inflammation plays a central role, with each condition exacerbating the other. Pyroptosis, an inflammatory form of programmed cell death, is implicated in periodontitis and diabetes. The activation of gasdermin D (GSDMD), a key mediator of pyroptosis, promotes cytokine release and perpetuates tissue destruction in both.
