- Brief Summary
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.
- Detailed Description
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.

Group Intervention Description Class V Glass ionomer - GIC Restorations Retrospective evaluation of RMGI and GIC Class V Restorations Glass ionomer (GI - Fuji 9) Class V restorations performed by by 3rd and 4th-year dental students in adult patients of Schulich dental clinic over the last three years will be evaluated using mirrors and probes. Class V RMGI Restorations Retrospective evaluation of RMGI and GIC Class V Restorations Resin-modified glass ionomer (RMGI - Fuji 2 LC) Class V restorations performed by by 3rd and 4th-year dental students in adult patients of Schulich dental clinic over the last three years will be evaluated using mirrors and probes.
- Primary Outcome Measures
Name Time Method Post-Operative Sensitivity 2 years 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)
Surface Roughness 2 years Surface texture of the restoration is similar to tooth structure (manually checked with the tip of a dental hand instrument - explorer)
Marginal Integrity 2 years Restoration closely adapted to the tooth. No crevice visible (manually checked with the tip of a dental hand instrument - explorer)
Secondary Caries 2 years 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)
Anatomic Form 2 years Restoration's anatomy is continuous with existing anatomic form of remaining tooth structure (checked visually with a dental intra-oral mirror)
Color match 2 years No difference between the tooth and restoration colour (checked visually with a dental intra-oral mirror)
Marginal Discolouration 2 years No visual evidence of dark discolouration adjacent to the margins of the restoration (checked visually with a dental intra-oral mirror)
