Photobiomodulation in recurrent aphthous stomatitis management using three different laser wavelengths. A randomized clinical trial.

Recurrent aphthous stomatitis (RAS) is a common oral lesion with no definitive treatment; current therapies primarily focus on symptom relief. This study aims to address the lack of high-quality clinical research by evaluating the effectiveness of Photobiomodulation Therapy (PBMT) using GaAlAs 808 nm, AlGaInp 660 nm, and GaAs 635 nm lasers for managing aphthous lesions. The study focuses on the lasers' effectiveness in reducing pain, accelerating healing, enhancing patient satisfaction, and preventing recurrence compared to a control group.

Evaluation of Surface Roughness of Translucent Zirconia After Applying Nd:YAG and CO2 Lasers: An In Vitro Study.

Background And Objectives: Surface roughness is one of the most important factors that play an important role in increasing the connection between the surface of the tooth and the applied restoration. Due to the increased interest in zirconia and the improvement of its mechanical and aesthetic properties, studies have increased that work to improve and increase its surface roughness so that it can be used as a veneer in the future. This study aims to compare the effect of two types of lasers on the surface of highly transparent zirconia to evaluate the surface roughness resulting from the two techniques.

Background: Deep bite is a common characteristic of malocclusion, and many methods are used to treat it, including mini-implants used for the intrusion of the upper incisors. Orthodontically induced inflammatory root resorption (OIIRR) is an inevitable and unexpected side effect of orthodontic therapy. However, resorption of the root could be affected by the type of tooth movement, such as intrusion.

Salivary-Based Cell-Free Mitochondrial DNA Level Is an Independent Prognostic Biomarker for Patients with Head and Neck Squamous Cell Carcinoma.

Changes in the copy numbers of cell-free nuclear DNA (cf-nDNA) and cell-free mitochondrial DNA (cf-mtDNA) have shown promising diagnostic utilities among patients with head and neck squamous cell carcinoma (HNSCC). Considering the absence of objective prognostic tools for HNSCC surveillance, this study aimed to assess the utility of saliva-based cf-nDNA and cf-mtDNA in predicting the overall survival of patients with HNSCC. The study included ninety-four patients with a confirmed HNSCC diagnosis with a mean follow-up time of 32.

Saliva-based cell-free DNA and cell-free mitochondrial DNA in head and neck cancers have promising screening and early detection role.

Background: Cell-free DNA (cfDNA) and cell-free mitochondrial DNA (cf-mtDNA) have been postulated as potential diagnostic and prognostic biomarkers for different human malignancies. Early detection of head and neck malignancies is fundamental for optimal patient management. This study, therefore, aimed to assess the utility of saliva-based liquid biopsy as a noninvasive source of cfDNA and cf-mtDNA for detecting head and neck cancer (HNSCC).

Cleidocranial dysplasia with hypermobile Ehlers-Danlos syndrome: A case report.

Cleidocranial dysplasia (CCD) is a rare genetic skeletal syndrome. The most common features are open fontanelles, hypertelorism, mid-face retrusion, hypoplasia, or aplasia of the clavicles leading to excessive shoulder mobility, dental abnormalities such as supernumerary, and impacted teeth. This case report describes a 31-year-old male with CCD with several unusual symptoms like generalized joint hypermobility, skin laxity, and smooth skin, which leads to set a diagnosis of hypermobile Ehlers-Danlos syndrome (hEDS).

Comparative study between using a tissue adhesive (N-BCA & OCA) and surgical sutures in free gingival graft surgery: A randomized controlled clinical trial.

Background: The success of periodontal surgery depends on the appropriate coaptation of the incised edges, the elimination of empty spaces and the reduction of the amount of blood coagulum. In free gingival graft (FFG) surgery, the stabilization of the graft, hemostasis and cleansing the site remain a necessity.

Objectives: The aim of the present study was to compare the use of the tissue adhesive N-butyl cyanoacrylate + octyl cyanoacrylate (N-BCA + OCA; Iceberg-glue®) and surgical sutures to evaluate the stabilization and fixation of FGG, which is indicated to increase the width of the keratinized attached gingiva.

Background: Despite the positive effect of the photobiomodulation therapy (PBMT) application on animals, the primary role of this technique on the human condyle is still unclear. Several experimental reports have shown the efficacy of PBMT in inducing cellular changes in the temporomandibular joint (TMJ) region during functional treatment of patients with skeletal deformities. Still, the lack of information about its effects on human condyles requires further studies.
