Gingival Phenotype and Dental Crowding in Pediatric Patients

The periodontal phenotype influences treatment outcomes across dental specialties, as tissues of different thickness respond differently to chemical, bacterial, and mechanical insults. In pediatric patients, understanding the gingival phenotype is particularly relevant: a thin phenotype may predispose to dehiscence, fenestration, and gingival recession-especially at the mandibular incisors-when tooth movement exceeds the biological limits of the bony housing. During the mixed dentition phase, significant changes in soft and hard tissues affect tooth position and periodontal stability, making early phenotype assessment essential. Interceptive orthodontics can reduce the long-term risk of mucogingival defects; early identification of a thin biotype allows for preventive strategies, including soft tissue grafting before critical orthodontic movements. No studies have examined the association between dental crowding severity and periodontal phenotype in children. Adult data remain inconsistent: Kaya et al. found no correlation between phenotype and skeletal malocclusion, while Kong et al. reported a site-specific association between thin biotype and skeletal Class I/III at the mandibular central incisor. No predictive model exists for periodontal risk related to severe crowding in childhood. This study aims to assess the periodontal phenotype in pediatric patients across different stages of dental transition and to investigate a possible association between a thin periodontal biotype and severe dental crowding.

Titanium-prepared Platelet-rich Fibrin for Treatment of Gingival Recession Using the VISTA Technique

This split-mouth randomized clinical trial aims to compare the effectiveness of titanium-prepared platelet-rich fibrin (T-PRF) and connective tissue graft (CTG) in the treatment of Miller Class I and II gingival recession using the Vertical Incision Subperiosteal Tunnel Access (VISTA) technique. Twenty systemically healthy adult participants with bilateral gingival recession defects will receive both interventions, with one side randomly assigned to T-PRF and the contralateral side assigned to CTG. Clinical outcomes including recession depth, attached gingival width, probing depth, relative attachment level, healing, and patient satisfaction will be evaluated over a 6-month follow-up period.

NOVOSYN® Quick Versus MONOSYN® Quick Suture Material in Resective Periodontal Surgery

The aim of this study is to prove that Novosyn Quick and Monosyn Quick are equivalent in early wound healing in adult patients undergoing resective periodontal surgery. In order to show equivalence between Novosyn Quick and Monosyn Quick EHS, which is composed of 3 parameters: clinical signs of reepithelization, clinical signs of haemostasis and clinical signs of inflammation, will be calculated for each suture 10 ± 5 days postoperatively and cannot differ more than 2 points. Furthermore, complications, the handling of the suture material, pain, satisfaction of the patient and bacterial contamination of the thread (optional) will also be assessed as secondary objectives.

OCT Vibrography for Biomechanical Properties of Tissues

The overall goal of this study is to develop OCT Vibrography (aka OCT elastography) as a novel tool for measuring biomechanical properties of human tissues in vivo.

Biofiller and Gingival Phenotype Thickening

The periodontal phenotype is defined as the combination of the gingival phenotype and the thickness of the buccal bone plate (bone morphotype). The gingival phenotype refers to the gingival thickness (GT) and the width of the keratinized tissue (KTW). A gingival thickness of ≤1 mm is classified as a thin phenotype, whereas a thickness \>1 mm is considered a thick phenotype. Thin gingival biotypes tend to show more pronounced responses to inflammation, restorations, trauma, and parafunctional habits. Various methods are used to assess gingival thickness, including transgingival probing (TP), ultrasonic measurements, cone-beam computed tomography (CBCT) scans, visual assessment, and colored biotype probes (CBP). Periodontal plastic procedures performed using autogenous grafts such as connective tissue grafts (CTG) and free gingival grafts (FGG), or biomaterials such as acellular dermal matrices (ADM) and collagen matrices (CM), are known to significantly increase GT and the amount of keratinized tissue. However, creating a second surgical site in the oral cavity during these procedures may compromise patient comfort, prompting researchers to explore alternative methods. Additionally, the effectiveness of synthetic biomaterials has been found to be lower than that of autogenous grafts. Platelet-rich concentrates have been used as a minimally invasive procedure for the past thirty years, showing a high capacity to release growth factors that support tissue regeneration. While platelet-rich plasma (PRP), as the first-generation platelet concentrate, is widely used, platelet-rich fibrin (PRF) has been increasingly applied across various fields of medicine and dentistry due to its ability to release more growth factors over a longer period, resulting in better clinical outcomes. PRF is a highly biocompatible material composed of autologous cells and growth factors entrapped in a fibrin matrix, and has been shown to degrade more slowly over time compared to conventional PRP. One of the main reported disadvantages of PRF (and especially PRP) is its relatively rapid resorption, typically within 2-3 weeks. Biofiller is an autologous material derived from the patient's own blood and includes platelet-poor plasma (PPP) and concentrated platelet-rich fibrin (PRF). The PPP component is heated to become enriched with albumin, thereby prolonging its resorption time. The PRF portion contains autologous cells and growth factors. However, conventional PRF is typically resorbed within 2-3 weeks, limiting its clinical application. Recent studies have shown that the resorption time of biofiller-a combination of PPP and PRF-can exceed 4 months. The aim of this study is to compare the effectiveness of biofiller with connective tissue graft in increasing gingival thickness in patients with a thin gingival phenotype. A total of 34 patients (17 patients in each group) will be enrolled. Tunnel surgery will be performed to all participants and test group will receive biofiller only once. Control group will receive connective tissue surgery. Clinical parameters obtained from our patients at baseline and at follow-up visits at 1, 3, and 6 months - including gingival thickness (GT), keratinized tissue width (KTW), and soft tissue measurements assessed via intraoral scanners - will be compared.

How Can Prefabricated Membranes Load Ascorbic Acid Can Curtail Gingival Recession?

Periodontal diseases are a prevalent issue, often leading to gingival recession, where the gingival margin recedes, exposing the tooth root and causing various problems. Gingival recession can be managed through both non-surgical and surgical interventions The non-surgical approach often involves plaque control and addressing any underlying inflammatory conditions. However, in cases of advanced recession, surgical treatment may be necessary Several treatment techniques have been proposed, which can be divided into pedicle and free grafts. The latter can also be classified as free gingival grafts (FGG) or as connective tissue grafts (CTG). Other treatment options include soft tissue substitutes or regenerative therapies Harvesting graft from the palate has several problems, such as pain, inflammation, bleeding, flap necrosis, and infection at the donor site. For this reason, we need a substitute for soft tissue graft harvesting Carbopol polymers, also known as carbomers, are widely utilized in pharmaceutical formulations for their excellent mucoadhesive properties. This high molecular weight, cross-linked acrylic acid polymers are particularly effective in enhancing the adhesion of formulations to mucosal surfaces, thereby improving drug delivery and bioavailability

Effectiveness of MySmile App for Improving the Oral Health of Secondary School Children:

The goal of this cluster-randomised control trial is to assess the effectiveness of the MySmile app for improving oral health in secondary school children. The main questions it aims to answer are: 1. Will the MySmile app be more effective in improving secondary school children's dental plaque and gingival health over and above the existing school dental service (SDS)? 2. Will the MySmile app be more effective in improving secondary school children's oral health knowledge, attitudes, and behaviours over and above the existing SDS? 3. Is the MySmile app easy to use by secondary school children? 4. Is the MySmile app acceptable to use from the perspective of secondary school children? Participants in the intervention group will receive the SDS and MySmile app. The control group will receive SDS only. Therefore the researcher will compare between the intervention and control group in terms of dental plaque, gingival health, oral health knowledge, oral health attitudes and oral health behaviours.

Evaluation Of Nonsurgical Treatment Of Deep Periodontal Pockets (7-10mm) Using AIRFLOW® Prophylaxis Master Device With Erythritol Powder vs Conventional Instrumentation

Periodontitis is a chronic condition associated with the inflammatory destruction of the periodontal tissues ultimately leading to tooth loss. Clinically, it is identified by key features such as clinical attachment loss (CAL), bleeding upon probing (BOP), and an increase in probing pocket depth (PPD), and/or gingival recession. Periodontitis is mediated by polymicrobial dysbiosis with keystone pathogens affecting the virulence of the entire biofilm community. The removal of this biofilm and its retention factors is the ultimate goal of clinical treatment and oral measures applied. The elimination of the biofilm has traditionally been achieved with the use of either hand instruments or power driven devices. Promoting periodontal health or diminishing bacterial presence and calculus buildup on teeth can be accomplished with the same efficacy whether using manual scalers and curettes or ultrasonic scaling instruments. Both hand and ultrasonic instruments are characterized by being time- consuming and requiring technical skill, often causing patient discomfort and post-treatment pain, including hypersensitivity resulting from the loss of hard tissue when scaling the tooth surface. Ultrasonic instruments tend to leave a rougher surface behind compared to hand instruments. While effective the current techniques all have their disadvantages. The aim of this study is to evaluate changes in probing depth clinically, Bleeding on probing, Clinical attachment level, Plaque index, Calculus index, Patient pain/discomfort, Patient satisfaction, Cost effectiveness, Treatment time and Number of pockets closed after using AIRFLOW® Prophylaxis Master device with erythritol powder.
