Effect of Surface Treatment and Cement on Fracture Load of Traditional Zirconia (3Y), Translucent Zirconia (5Y), and Lithium Disilicate Crowns.

Purpose: To determine if surface treatment and cement selection for traditional 3 mol% yttria partially stabilized zirconia (3Y-PSZ), "translucent" 5 mol% yttria-stabilized zirconia (5Y-Z), or lithium disilicate crowns affected their fracture load.

Materials And Methods: Crowns with 0.8 mm uniform thickness (96, n = 8/group) were milled of 3Y-PSZ (Lava Plus), 5Y-Z (Lava Esthetic), or lithium disilicate (e.

Factors influencing the progression of noncarious cervical lesions: A 5-year prospective clinical evaluation.

Statement Of Problem: The etiology (chemical, friction, abfraction) of noncarious cervical lesion (NCCL) progression is poorly understood.

Purpose: The purpose of this 5-year prospective clinical trial was to measure the relationship between NCCLs and various etiologic factors.

Material And Methods: After review board approval, 29 participants with NCCLs were enrolled.

Cervical dentin hypersensitivity. Part III: resolution following occlusal equilibration.

Objective: This retrospective study was designed to investigate changes of cervical dentin hypersensitivity (CDH) in response to occlusal equilibration.

Method And Materials: Written records for 250 active-care patients were randomly selected and analyzed for associations between CDH, and its resolution following occlusal equilibration. Patients in group A (treatment) and B (delayed treatment) received occlusal equilibration following the detection of verified CDH using the air indexing method.
