electrical impedance device (prepometer), digital radiography, remaining dentin thickness
Brief summary
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.
Interventions
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.
A digital periapical radiograph using paralleling technique was taken

Study design
Masking description
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
Eligibility
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 ¼ dentin thickness or previously restored.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| validity of the two devices | Through study completion, an average of 1 year | Level of agreement between the digital radiograph and the device in measurement of remaining dentin thickness |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patients satisfaction between two devices | Through study completion, an average of 1 year | By visual analogue scale Visual Analog Scale (VAS) which is a 100 mm straight horizontal line with the left end indicating •not at all satisfied- and the right end very satisfied. |
