Facial gingival surfaces of maxillary and mandibular anterior teeth were monitored to evaluate changes of the width of the keratinized and attached gingiva. 96 children 6 to 12 years of age were examined 2 x with an interval of 2 years. Measurements included dental plaque, gingival inflammation, probing depth, and width of keratinized and attached gingiva. In addition, study models were used to determine the facial/lingual position of the teeth. The results of this report, evaluating well-aligned teeth only, showed that during the 2-year observation period, increases in widths of the facial keratinized and attached gingiva took place. Increases occurred for the various teeth regions examined, and for deciduous as well as permanent teeth. During transition from the deciduous to the permanent dentition, patterns of change were variable. The increase of gingival widths was greatest for sites with the smallest baseline width of attached gingiva, and smallest for sites with the greatest baseline width. It was concluded that in well-aligned teeth, a conservative, monitoring approach prior to a corrective, surgical intervention seems prudent in children of this age with a minimal zone or absence 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.
