So the age determination of an individual by examination of teeth is one of the accepted methods in legal system. A review of the literature shows there are differences in eruption pattern between different populations mainly due to variations in the constitutions and environment, so highl...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...

BACKGROUND Estimation of teeth-to-vallecula distance would facilitate the selection of properly sized oropharyngeal airways in young children. The aims of the present study were to measure the teeth-to-vallecula distance and to create an algorithm to predict this distance based on anatomical landmarks and patient characteristics in children. METHODS Two hundred children, aged 1-9 yr, undergoi...
Aims: This study aimed to determine the prevalence of endodontic-periodontal lesions (EPLs) and EPL grades 1–3 without root damage in patients with periodontitis according 2017 World Workshop on Classification Periodontal Peri-Implant Diseases.
 Methods: included 500 panoramic radiographs from Faculty Dentistry at University İstanbul Medipol. Each radiograph was evaluated by a calibrated i...
