Exposure of maxillary gingiva more than 3 mm while smiling is referred to as "excessive gingival display" or "gummy smile." Various treatment options for excessive gingival display are published in the literature, including lip repositioning, crown lengthening, botulinum toxin-A injections, and orthognathic surgeries. This case report aims to present a novel approach to the lip-repositioning procedure for treatment of excessive gingival display. The patient, who visited the department to demand a more esthetic smile, was diagnosed with excessive gingival display caused by hyperactivity of upper lip muscles. Lip repositioning procedure was considered. While evaluating the patient's smile, the amount of gingival display for each tooth region varied. A novel tooth-based modification was planned for the patient for a more precise result. No complication was noted during 10- and 30-day follow-ups. The amount of gingival display while smiling was less than 3 mm for each tooth region. The tooth-based lip-repositioning technique may provide an opportunity to more precisely treat patients with gummy smile.

Objective: This study aimed to evaluate bone remodeling in gingival crevicular fluid (GCF) during canine distalization in obese individuals and compare it to that in normal-weight individuals. Additionally, the orthodontic tooth movement rates of obese individuals were measured and compared with those of normal-weight individuals.
Methods: Thirty-six patients (18 obese and 18 normal-weight) aged 12-18 years who were candidates for maxillary first premolar extraction for Angle Class II malocclusion were included in the study.
Short dentin etching with universal adhesives: effect on bond strength and gingival margin adaptation.

Background: Short dentin etching, a relatively recent technique, aims to improve resin-dentin bonding by preserving hydroxyapatite crystals within the collagen spaces. This study explores short dentin etching's potential in mitigating over-etching issues in deep proximal dentin/cementum margins, an aspect not previously investigated. This study evaluates the microtensile bond strength (μTBS) and marginal adaptation of two universal adhesives using different etch-and-rinse strategies (15-second and 3-second etching) and self-etch strategies, both immediate and post-thermal cycling and mechanical loading.

Statement Of Problem: Staining at the gingival margin could impact denture longevity, but the behavior of gingival colored composite resins (GCCs) in this area remains unclear.
Purpose: This in vitro study evaluated surface staining, microleakage, and push-out bond strength at the gingival margin of artificial teeth, comparing two consistencies of GCCs with two resin base materials.
Material And Methods: Specimens included artificial teeth (Ivostar; Ivoclar AG) and two acrylic resin base materials: conventional (Ondacryl; Clássico) and high-impact (Diamond D; Keystone Industries) (n=300).
Role of Injectable Platelet-Rich Fibrin in the Management of Soft and Hard Tissue Periodontal Regeneration in Dentistry: Protocol for a Systematic Review.

Background: Injectable platelet-rich fibrin (i-PRF) has the capacity to release great amounts of several growth factors, as well as to stimulate increased fibroblast migration and the expression of collagen, transforming growth factor β, and platelet-derived growth factor. Consequently, i-PRF can be used as a bioactive agent to promote periodontal tissue regeneration.
Objective: We aim to compare and evaluate the effectiveness of i-PRF in periodontal tissue regeneration.

Aim: To propose a modified method for establishing a peri-implantitis murine model, assess the gene expression profile and immune cell infiltration of the gingiva and alveolar bone, and evaluate the transcriptomic similarity between patients with peri-implantitis and the corresponding murine model.
Materials And Methods: A ligature-induced peri-implantitis murine model was established using an immediate implant placement approach. RNA sequencing was performed to determine the transcriptomic profiles of peri-implant tissues from mice, patients with peri-implantitis and healthy individuals.
