Filter by:The study will be divided into two parts: In vivo part and in vitro part.In vivo part: It will be a randomized clinical trial using split mouth technique on 44 primary molars in children aged from 4-8 years old selected from outpatient clinic of Department of Pediatric Dentistry, Faculty of Dentistry, Suez Canal University. The selected primary molars will be divided randomly into two main groups ,each group will be subdivided into two subgroups according to types of crowns that will be used as follows:- Group I:- comprise of 22 primary molars that will be subdivided into two subgroups, subgroup IA:-includes 11 primary molars will be restored by stainless steel crowns and subgroup IB:-includes 11 primary molars will be restored by zirconia crowns, Group II:- comprise of 22 primary molars that will be subdivided into two subgroups, subgroup IIA:-includes 11 primary molars will be restored by stainless steel crowns and subgroup IIB:-includes 11 primary molars will be restored by fiberglass crowns. The three types of crowns will be evaluated at the baseline once after cementation of the crowns and after one week,1 ,3,6,9 and 12 months follow up by using the following methods modified United States Public Health Service criteria, in terms of color match, marginal integrity, secondary caries and crown fracture, the gingival marginal status and parental satisfaction. In vitro part: It will be carried out on 30 mandibular primary molars, 15 mandibular first primary molars for microleakage test and 15 mandibular second primary molars for crown fracture resistance test for three crowns types.
Parallel clinical trial focusing on procedural pediatric sedation in the dental setting. Children will be randomized to treatment according to a predetermined sequence of interventions consisting of: 1. intranasal sedation with ketamine-associated dexmedetomidine (Experimental Group), 2. intranasal sedation with dexmedetomidine as sole drug (Control Group). Primary outcome is children's behavior during the dental treatment. Secondary outcomes are: children's pain, memory and stress (salivary cortisol and melatonin); perception of the accompanying adult, dentist and child about dental sedation; cost-effectiveness of this type of sedation; psychosocial variables; children's quality of life.
