Dentists can reliably detect premature tooth contacts of 50 microns or more using digital palpation. Most dentists prefer a single forefinger method for evaluating occlusal prematurity.

Area of Science:

  • Dental Diagnostics
  • Occlusion and Biomechanics

Background:

  • Premature occlusal contacts can lead to various dental issues, including temporomandibular disorders and occlusal trauma.
  • Accurate detection of these contacts is crucial for effective diagnosis and treatment planning in restorative and orthodontic dentistry.

Purpose of the Study:

  • To survey dentists' preferred methods for palpating teeth to evaluate premature contacts.
  • To assess dentists' ability to discriminate degrees of occlusal prematurity using different palpation techniques.
  • To measure the digital pressure applied during palpation.

Main Methods:

  • A survey of 30 dentists regarding their palpation techniques for premature contacts.
  • A discrimination test involving 38 dentists evaluating occlusal prematurity with two palpation methods.

  • Measurement of digital pressure exerted by dentists during palpation.

    • Main Results:

    • The majority of dentists favored using a single forefinger on the facial surfaces of central incisors for palpation.
    • Most dentists could reliably identify occlusal interference of 50 microns or greater.
    • Reliable detection of prematurity was achieved irrespective of the palpation method employed.

    Conclusions:

    • Dentists possess a reliable ability to detect significant occlusal prematurity (≥50 microns) through digital palpation.
    • The chosen palpation method, typically a single forefinger, appears effective for identifying premature contacts.
