Retrospective Evaluation of RMGI/GI Class V Restorations

Western University, Canada36 enrolled

Overview

Brief Summary: Retrospective study to evaluate the clinical performance of two restorative materials - glass-ionomer (GI) and resin-modified glass-ionomer (RMGI) materials - in Class V carious and non-carious cervical lesions restored by dental students.

The aim of this retrospective study was to evaluate the clinical performance of glass-ionomer (GI) and resin-modified glass-ionomer (RMGI) materials in Class V carious and non-carious cervical lesions restored by dental students. Ninety-six (96) restorations performed with either GI (Fuji IX) (n=39) or RMGI (Fuji II) (n=57) were evaluated using the modified USPHS (United States Public Health Systems) criteria by two independent investigators at two follow-up evaluations (two years apart). The Fisher statistical test was used to compare USPHS criteria and examine significant differences by setting p\<0.05 for statistical significance and the Kaplan-Meier algorithm was used to calculate the survival probability.

Outcomes

Primary Outcomes

Post-Operative Sensitivity

Absence of sensitivity to pressure, cold or hot temperature on the teeth restored (checked verbally by inquiring the patient about the presence or absence of pain in the presence of stimuli)

Time frame: 2 years

Secondary Caries

No visual evidence of dark, deep discolouration or cavitation adjacent to the restoration (visually and manually checked with the tip of a dental hand instrument - explorer)

Time frame: 2 years

Anatomic Form

Restoration's anatomy is continuous with existing anatomic form of remaining tooth structure (checked visually with a dental intra-oral mirror)

Time frame: 2 years

Color match

No difference between the tooth and restoration colour (checked visually with a dental intra-oral mirror)

Time frame: 2 years

Surface Roughness

Surface texture of the restoration is similar to tooth structure (manually checked with the tip of a dental hand instrument - explorer)

Time frame: 2 years

Marginal Discolouration

No visual evidence of dark discolouration adjacent to the margins of the restoration (checked visually with a dental intra-oral mirror)

Time frame: 2 years

Marginal Integrity

Restoration closely adapted to the tooth. No crevice visible (manually checked with the tip of a dental hand instrument - explorer)

Time frame: 2 years
