Observational Study of OROSEDAL in Sore Throat and Minor Oral Lesions

This prospective, multicenter, national, observational, non-interventional post-market clinical follow-up study will evaluate the performance and safety of OROSEDAL in children and adults with sore throat or minor oral lesions, including minor aphthous ulcers and histologically confirmed oral lichen planus. OROSEDAL is prescribed in routine practice before inclusion. Patients will be followed for 6 ± 1 days and will complete self-assessments of pain, swallowing discomfort, treatment use, and adverse events.

Salivary E-cadherin, Calprotectin, and Matrix Metalloproteinase-9 Levels in Recurrent Aphthous Stomatitis

The goal of this observational cross-sectional study is to determine the salivary levels of E-cadherin, Calprotectin, and Matrix Metalloproteinase-9 (MMP-9) in patients with Recurrent Aphthous Stomatitis (RAS) and to compare them with those of healthy controls. The main questions it aims to answer are: Are the salivary levels of E-cadherin, Calprotectin, and MMP-9 significantly different in patients with minor RAS compared to healthy controls? Can these salivary proteins serve as biomarkers involved in the pathogenesis of minor RAS? Researchers will compare patients with minor RAS and healthy individuals to determine whether differences in salivary E-cadherin, Calprotectin, and MMP-9 levels are associated with the presence of disease. Participants will: Provide unstimulated saliva samples using a saliva swab Undergo clinical evaluation for periodontal status (Community Periodontal Index - CPI) and caries experience (DMFT index) Collected saliva samples will be stored at -80°C until analysis. The concentrations of the investigated proteins will be measured using ELISA kits, and total protein levels will be determined using a colorimetric protein assay. The relationships among the salivary concentrations of the investigated proteins, as well as their associations with demographic variables such as age and sex, will be analyzed.

Effects of Photobiomodulation (PBM) on Pain After Presentation of Aphthous Ulcers in Pediatric Dental Patients

The purpose of this study is to compare the efficacy of laser photobiomodulation and "Magic Mouthwash" for treatment of pain in pediatric patients with aphthous ulcers , to assess how photobiomodulation influences the rate of healing of aphthous ulcers in pediatric patients and to measure changes in pain levels reported by pediatric patients undergoing photobiomodulation treatment for aphthous ulcers.
