Brief Summary:
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.
Detailed Description:
The study 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 after approval of Research Ethics Committee (REC) of the Faculty of Dentistry, Suez Canal University. The children participants and legal guardian of each participant will be assigned on informed consent of treatment procedures they will receive.
A total of 44 primary molars will be included in this study using split mouth technique to ensure equalizing variables for both groups.
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.
* 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.
* Subgroup IIB: includes 11 primary molars will be restored by fiberglass crowns.
II.4 Clinical Procedures:
* Eligibility criteria will be verified after the clinical and periapical radiographic examination.
* The selected primary molars will be anesthetized to reduce discomfort during preparation.
* Tooth preparation and crown cementation will be performed for each tooth according to the manufacture's instruction for each type of crowns.
II.5 Methods of evaluation:
The evaluation of each crown will be assessed at the baseline once after cementation and after one week,1, 3, 6,9 and 12 months follow up by using the following methods:
II.5.1 Modified United States Public Health Service (USPHS) criteria:
Modified United States Public Health Service (USPHS) criteria will be used in terms of marginal integrity, secondary caries, color match, and crown fracture
