Goodacre NCCL Review 2022

Question 1

1, 2. Two types of NCCL shapes per the Goodacre review?

3. Most commonly affected teeth?

Answer 1

1. Rounded (saucer-like)
2. V-shaped indentation
3. Max premolars or mand premolars, then canines or maxillary molars (different studies say different things)

Question 2

What does it mean when there have been “no smoking gun” for abfraction lesions?

What is used to model this phenomena instead?

Answer 2

Clinical studies have not observed cracks or particulate material near the surface of a cervical lesion clinically. Lesion progression is slow and evidence washed away.

2. Finite Element Analysis - Occlusal loads of 200 N are 10-greater for non axial loading. Failing under surface compression.

Question 3

Is there a best restoration for NCCL’s per Goodacre’s review? If not, what did they recommend?

Is there a best adhesive agent?

Answer 3

No, none identified as best. The authors of the paper like composite resin due to good bonding, surface smoothness, color matching, and established clinical performance.

No best adhesive agent. Three step, two step, and one step
