Microstrain in Maxillary Premolars With Noncarious Cervical Lesions Before and After Restoration: A Randomized Clinical Trial.

Key Points

• This research aims to assess how restoration impacts microstrain in maxillary premolars with noncarious cervical lesions.
• Conducted a randomized clinical trial on maxillary premolars with NCCLs.
• Applied restorative materials: RMGIC and RC.
• Measured coronal buccal microstrain before and after restoration.
• Significant reduction in microstrain observed post-restoration with RMGIC.
• RC restoration also showed decreased microstrain.
• Both restorative techniques improved the mechanical stability of the teeth.
