Summary

The minimum lateral wall height (LWH) for a Class I cavity preparation of 0.8 mm width is typically 2.0 mm or less in posterior teeth. This study quantified LWH in human teeth to inform cavity preparation guidelines.

Area of Science:

  • Dental materials science and biomaterials
  • Restorative dentistry
  • Tooth anatomy and morphology

Background:

  • Class I cavity preparations are fundamental in restorative dentistry.
  • Understanding the minimum lateral wall height (LWH) is crucial for effective cavity design.
  • Previous research has not definitively established LWH parameters for specific cavity dimensions.

Purpose of the Study:

  • To quantify the minimum necessary lateral wall heights (LWH) for a Class I cavity preparation.
  • The preparation was defined as 0.8 mm in width and extending to the dentin-enamel junction.
  • Measurements were taken from extracted human permanent posterior teeth.

Main Methods:

  • 183 undecalcified sections from 73 posterior teeth were analyzed.

Related Experiment Videos

  • Digital images of fissures were captured, and LWH was measured using a computer-generated device.
  • Data was analyzed by tooth type, including mean, minimum, maximum, and frequency distribution.

    • Main Results:

    • Lateral wall heights (LWH) ranged from 1.2 mm to 2.5 mm.
    • The mean LWH was 1.925 mm (SD=0.262 mm), with 2.0 mm being the most frequent measurement (18%).
    • Seventy percent of LWHs were 2.0 mm or less, and maximum LWH positively correlated with bucco-lingual crown width.

    Conclusions:

    • The study provides quantitative data on LWH for specific Class I cavity preparations.
    • Findings suggest that LWH generally does not exceed 2.0 mm in the tested posterior teeth.
    • This data can inform clinical guidelines for conservative cavity preparation in restorative dentistry.
