Efficacy of Calcium Silicate Pulp-capping; a Randomized Controlled Clinical Trial

March 1, 2017 updated by: King's College London
This study aims to investigate the tooth nerve response to a recently introduced therapeutic filling material (calcium silicate cement) called Biodentine and to assess the quality of the overlying filling compared to another material (glass ionomer cement) called Fuji IX used more commonly. Also to compare the effectiveness of cone beam computed tomography x-rays compared to conventional periapical x-rays in detecting lesions around these teeth.

Detailed Description

Tooth decay is one of the most widespread diseases in the world. Very often, a patient comes to the dental clinic when experiencing pain which commonly means the decay is deep and is very close to or has penetrated the nerve of the tooth. When the decay is very close to the pulp or nerve of the tooth, a procedure called pulp capping is done in an attempt to save the tooth and to prevent root canal treatment. A material has been introduced to the market for this purpose, called Biodentine. This study aims to investigate the nerve response to this material and to assess the quality of the overlying filling compared to another material (glass ionomer cement) used more commonly. Also, X-rays are a routine procedure used to assess how close the decay is to the nerve and to see if there are abnormalities around the tooth. However conventional X-rays may not be accurate. A new technique called Cone Beam Computed Tomography (CBCT) has been developed which shows a 3-D image of the tooth and may be more accurate. We aim to compare the images gained from conventional X-rays and CBCT to help improve diagnosis and care planning for patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Yes

  1. Patients either male or female over the age of 16 (who can consent for themselves) in good general health
  2. A minimum of one carious lesion (occlusal, proximal, or MOD)
  3. Positive pulp response to electric pulp test and thermal stimulation.

Exclusion Criteria:

  1. Patients with clinical symptoms of irreversible pulpitis who need root canal treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The principal outcome of the study is whether the tooth restored with the test or control material remains vital (alive) at follow-up examination.
Time Frame: up to 2 years
The vitality of the restored tooth (whether the nerve of the tooth is alive or dead) is determined clinically by a positive response to cold test, absence of spontaneous pain, negative sensitivity to percussion, absence of sinus/fistula/swelling and abnormal mobility, and absence/reduction of periapical radiolucencies as determined by PA radiographs.
up to 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The integrity of the composite restoration overlying the test or control material is either acceptable or not.
Time Frame: up to 2 years
As assessed clinically by USPHS criteria and Hickel's criteria for the assessment of dental restorations.
up to 2 years
The CBCT scans of the teeth restored with the test or control material are either more effective or are comparable to conventional radiographs in detecting the presence of early peri-radicular lesions associated with the restored teeth.
Time Frame: One year
One year
