Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The research question was that in patients with carious posterior permanent teeth, would the electrical impedance device be as valid as digital radiography in estimation of remaining dentin thickness? The proposed hypothesis was null.

The assessors will not be blind about the type of intervention/control assessment methods due to different application methods. However it will not be allowed amongst the examiners to exchange any information throughout the entire study period

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Reference test: Radiographic examination

Group Type EXPERIMENTAL

Reference test: Digital Radiographic examination

Intervention Type DIAGNOSTIC_TEST

A digital periapical radiograph using paralleling technique was taken

Index test: electrical impedance device, Prepometer

Group Type EXPERIMENTAL

electrical impedance device,

Intervention Type DIAGNOSTIC_TEST

The electrical resistance of the residual dentine underneath each measurement point was determined between an electrode and the crown pulp (Prepometer, Hager \& Werken, Duisburg, Germany). Assigning the electrical resistance of the dentin. high values are considered to represent more residual dentine than low values.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants eligible for this study were those aged from 18 y to 28 y,
* willing to join the study
* with clinically detectable occlusal or proximal carious vital permanent molar teeth with closed apex and healthy periodontal supporting.
* The minimum extension of the carious cavity should be at least 1 mm in width to accommodate with the probe of the prepometer

Exclusion Criteria

* Excluded participants were those with poor oral hygiene,
* severe medical complications,
* showing signs and symptoms of irreversible or necrotic pulp pathology also when the affected tooth was with extended buccal or lingual caries, extending clinically beyond ΒΌ dentin thickness or previously restored.
