What is the minimal depth required for a restoration according to standard dental procedures?

The minimal depth required for a restoration is crucial to ensure adequate retention and proper function of the filling material. The range of 0.5mm to 1.5mm is significant because it allows for sufficient space to remove decayed tooth material while still preserving healthy tooth structure. This depth helps in preventing fractures in the restoration and ensures that the restorative material bonds effectively to the dentin and enamel.

Restorative dentistry guidelines indicate that achieving the right depth is essential for the longevity of the restoration. If the cavity preparation is too shallow, the restoration may not adequately seal the cavity, leading to the possibility of recurrent decay or failure of the material. Conversely, deeper preparations can compromise the remaining tooth structure, putting the tooth at risk for fracture and increasing the chance of post-operative sensitivity.

The other ranges provided do not align with the standard practices that focus on a balance between removing decay and preserving healthy tooth tissue. Following established guidelines for cavity depth helps dental professionals create restorations that provide optimal outcomes for patient health and satisfaction.
