简要总结
The aim of this study was to evaluate the long-term clinical performance of two highly viscous encapsulated GICs (EquiaFil and Riva SC) covered with two different coatings (Equia Coat and Fuji Varnish) over 6-year using modified United State Public Health Service (USPHS) criteria.
A total of 256 restorations were made with EquiaFil and Riva SC. Equia Coat or Fuji Varnish was used randomly on the surface of the restorations. The restorations were evaluated at baseline, 6, 12, 18 months and 6 years after placement using modified USPHS criteria. The results were evaluated with Pearson Chi-Square and Mann Whitney U-test (p< 0.05).

The aim of this study was to evaluate the long-term clinical performance of two highly viscous encapsulated GICs (EquiaFil and Riva SC) covered with two different coatings (Equia Coat and Fuji Varnish) over 6-year using modified United State Public Health Service (USPHS) criteria.
Fifty-four patients having Class I and II restorations/caries were included in the study. A total of 256 restorations were made with EquiaFil (GC Corp, Japan) and Riva SC (SDI, Australia). Equia Coat or Fuji Varnish was used randomly on the surface of the restorations. After cavity preparations, the teeth were randomly restored with one glass ionomer cement and coated with Equia Coat or Fuji Varnish. The restorations were evaluated at baseline, 6, 12, 18 months and 6 years after placement using modified USPHS criteria. Two evaluators checked color-match, marginal discoloration, marginal adaptation, caries formation, anatomical form, postoperative sensitivity and retention rate and photographs were taken at each recalls. The results were evaluated with Pearson Chi-Square and Mann Whitney U-test (p< 0.05).
The 18-month results were presented at the CED IADR congress iheld in Barcelona in 2010 (Turkun LS, & Kanic O ,Clinical evaluation of new glass ionomer coating combined systems for 18-months Journal of Dental Research 89 (Special Issue B) Abstract #402.) Gurgan S et al. also mentioned our 18-month results in their published manuscript ( Gurgan S,Kutuk ZB, Ergin E, Oztas ZZ & Cakir FY (2015) Four-year randomized clinical trial to evaluate the clinical performance of a glass ionomer restorative system Operative Dentistry 40(2) 134-143).

结局指标
主要结局
Evaluating differently coated glass ionomer cements on posterior teeth with United State Public Health Service criteria regarding marginal adaptation by 2 independent evaluators
时间窗: 6 years
Marginal adaptation was evaluated by 2 independent clinicians. Visual inspection with a mirror at 18 inches was performed . A score means the higher score of clinical acceptability while C and D score means that the restoration has failed and needs to be replaced. Alpha 1: Harmonious outline Alpha 2: Marginal gap (max 100µ) with discoloration (removable) Bravo: Marginal gap (\> 100µ) with discoloration (unremovable) Charlie: The restoration is fractured or missed
Evaluating differently coated glass ionomer cements on posterior teeth with United State Public Health Service criteria regarding marginal discolouration by 2 independent evaluators
时间窗: 6 years
Marginal discolouration was evaluated by 2 independent clinicians. Visual inspection with a mirror at 18 inches was performed . A score means the higher score of clinical acceptability while C score means that the restoration has failed and needs to be replaced. Alpha: No discoloration anywhere along the margin between the restoration and the adjacent tooth. Bravo: Slight discoloration along the margin between the restoration and the adjacent tooth. Charlie: The discoloration penetrated along the margin of the restorative material in a pulpal direction.
Evaluating differently coated glass ionomer cements on posterior teeth with United State Public Health Service criteria regarding retention rate by 2 independent evaluators
时间窗: 6 years
Retention rate was evaluated by 2 independent clinicians. Visual inspection with a mirror at 18 inches was performed . A score means the higher score of clinical acceptability while C and D score means that the restoration has failed and needs to be replaced. Alpha 1:Clinically excellent Alpha 2: Clinically good with slight deviations from ideal performance, correction possible without damage of tooth or restoration Bravo: Clinically sufficient with few defects, corrections or repair of the restoration possible Charlie: Restoration is partially missed Delta: Restoration is totally missed
Evaluating differently coated glass ionomer cements on posterior teeth with United State Public Health Service criteria regarding anatomic form by 2 independent evaluators
时间窗: 6 years
Anatomic form was evaluated by 2 independent clinicians. Visual inspection with a mirror at 18 inches was performed . A score means the higher score of clinical acceptability while C score means that the restoration has failed and needs to be replaced. Alpha 1: Continuous with existing anatomical form Alpha 2: Slightly discontinuous due to some chipping on the proximal ridge Bravo: Discontinuous with existing anatomical form due to material loss but proximal contact still present Charlie: Proximal contact is lost with ridge fracture
Evaluating differently coated glass ionomer cements on posterior teeth with United State Public Health Service criteria regarding colour changes by 2 independent evaluators
时间窗: 6 years
Colour changes was evaluated by 2 independent clinicians. Visual inspection with a mirror at 18 inches was performed . A score means the higher score of clinical acceptability while C score means that the restoration has failed and needs to be replaced. Alpha: The restoration matches the adjacent tooth structure in color and translucency. Bravo: Light mismatch in color, shade or translucency between the restoration and the adjacent tooth. Charlie: The mismatch in color and translucency is outside the acceptable range of tooth color and translucency.
