In brief: The accuracy of the

measurement is not appreciably affected by using the inner vs the outer wall.
The accuracy will be the same. The question is which measure is a better predictor of root diameter with regard to clinical outcome. The answer is actually to measure from the leading edge to the leading edge of the root above the valve. In other words, the outer edge of the first seen root to the inner edge of the last
