Brief Summary:

Introduction and Research Problem:

The aim of this project is to evaluate and compare two full coronal restorations on primary posterior molars over a period of 3, 6 and 12 months in terms of restoration failure, marginal integrity, proximal contact, secondary caries, occlusion and gingival response. The restorations types are Stainless Steel Crowns (SSC) and NuSmile Zirconia Crowns (Nu/ZR).

Materials and Methods:

Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who need restorations will be screened for inclusion criteria till 120 teeth are recruited (60 teeth for SSC restorations and 60 for Nu/ZR restorations). Split mouth technique will be used to ensure equalizing variables for both groups, each patient will have side restored with SSC and the opposite side will be restored with Nu/ZR crowns.

Randomization will be done using Statistical Package for the Social Sciences (SPSS) software version 20.0 (Armonk, New York; International Business Machines Corporation (IBM Corp) for each age group separately with a uniform random variable generation. A simple descriptive statistics will be used for analysis and a T-Tests with Wilcoxon Signed-Rank will be used. Level of significance will be set at (α = 0.05) and level of confidence at (95%).

Primary Outcome Measures :
  1. Gingival health [ Time Frame: 3-month follow-up ]
    This parameter was evaluated using a blunt periodontal probe (Double ended probe Williams 1-2-3-5-7-8-9-10 Goldman Fox Flat) according to the Löe and Silness gingival index [Löe, 1967].

  2. Plaque index [ Time Frame: 3-month follow-up ]
    This parameter was evaluated using a blunt periodontal probe (Double ended probe Williams 1-2-3-5-7-8-9-10 Goldman Fox Flat) according to the Löe and Silness gingival index [Löe,1967].

  3. Restoration failure [ Time Frame: 3-month follow-up ]
    This was clinically evaluated with visual assessment of the restoration, according to the US Public Health Service "USPHS", Alpha criteria rating system [Ryge, 1980].
