About this study

Objective: To compare success rates of biodentine partial pulpotomy versus formocresol pulpotomy treatment of pulpally exposed lower primary molars.

After caries removal resulted in a pulp exposure, the pulp at the exposed area is amputated to a depth of 2 mm. The wound surface is irrigated and dried. After homeostasis is obtained, an assistant drew lots to randomly allocate the case to either the biodentine partial pulpotomy (PP) or the formocresol pulpotomy (FP) group.

The follow-up for clinical and radiographic evaluation will be carried out at 6-month intervals.

Read the detailed description
  • Prospective
  • Study population: 100 patients.
  • Study group: This study sample comprises mandibular primary molars from boys and girls aged between 3 and 7 years. The children have no systemic diseases according to the medical history supplied by the parents or guardians. The mandibular primary molars in this study are selected according to the following clinical and radiographic criteria. The clinical criteria: the presence of a deep carious lesion, sufficient tooth structure for restoration with a stainless steel crown, no history of spontaneous pain, tenderness to percussion or abnormal mobility, abscess, fistula, or swelling of the gingiva, and with cessation of bleeding after a 2 mm depth of the pulp at the area of the exposure was amputated. The radiographic criteria: a deep carious lesion in close proximity to the pulp without furcation or radicular pathology, obliteration of the pulp and root canal, or internal or external root resorption. Physiologic root resorption, while included in the criteria, could not be more than one-third of the root length.
  • Clinical technique: All teeth will be treated under local anaesthesia with rubber dam isolation. After caries removal resulted in a pulp exposure, the pulp at the exposed area is amputated to a depth of 2 mm using a water-cooled high-speed handpiece with a #330 high-speed bur. The wound surface is irrigated with sterile saline solution and dried with cotton pellets to avoid clot formation. After homeostasis is obtained, an assistant drew lots to randomly allocate the case to either the PP or the FP treatment group. The child will not know which treatment is assigned to each tooth. For the PP group, biodentine is gently applied to the wound surface, and then covered with reinforced zinc oxide-eugenol (IRM_; Dentsply). For the FP group, coronal access is obtained using high-speed handpiece with a #330 high-speed bur with water spray to further expose the pulp chamber. Following removal of the coronal pulp and achievement of homeostasis, a cotton pellet moistened with formocresol (1: 5 Buckley's solution) is placed on the amputated pulp for 5 min. The pulp stumps is then covered by IRM. After PP or FP treatment, all teeth are restored with a stainless steel crown.
  • Follow-up: the follow-up for clinical and radiographic evaluation will be carried out at 6-month intervals. Treatment is considered a clinical failure if one or more of the following signs are observed: pain, abscess or sinus opening, tenderness upon percussion, or abnormal tooth mobility. For radiographic evaluation, the treatment is rated as a failure when one or more of the following signs are present: furcation or periapical radiolucency, pathologic external root resorption, or internal resorption. The treatment is regarded successful if both the clinical and radiographic evaluation does not indicate any signs of failure.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • partial pulpotomy with biodentineProcedure or surgery

    After caries removal resulted in a pulp exposure, the pulp at the exposed area is amputated to a depth of 2 mm. The wound surface is irrigated and dried. After homeostasis is obtained, biodentine is gently applied to the wound surface, and then covered with reinforced zinc oxide-eugenol

  • Formocresol pulpotomyProcedure or surgery

    Following removal of the coronal pulp and achievement of homeostasis, a cotton pellet moistened with formocresol (1: 5 Buckley's solution) is placed on the amputated pulp for 5 min. The pulp stumps is then covered by IRM.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. partial pulpotomy clinical success rate

    Treatment is considered a clinical failure if one or more of the following signs are observed: pain, abscess or sinus opening, tenderness upon percussion, or abnormal tooth mobility. The treatment is regarded successful if clinical evaluation does not indicate any signs of failure.

    Measured: 6-month intervals, up to 2 years. From date of randomization until the date of first documented failure or up to 24 months

  2. partial pulpotomy radiographic success rate

    For radiographic evaluation, the treatment is rated as a failure when one or more of the following signs are present: furcation or periapical radiolucency, pathologic external root resorption, or internal resorption. The treatment is regarded successful if radiographic evaluation does not indicate any signs of failure.

    Measured: 6-month intervals, up to 2 years. From date of randomization until the date of first documented failure or up to 24 months

Secondary outcomes (2)
  1. Formocresol pulpotomy clinical success rate

    Treatment is considered a clinical failure if one or more of the following signs are observed: pain, abscess or sinus opening, tenderness upon percussion, or abnormal tooth mobility. The treatment is regarded successful if clinical evaluation does not indicate any signs of failure.

    Measured: 6-month intervals, up to 2 years. From date of randomization until the date of first documented failure or up to 24 months

  2. Formocresol pulpotomy radiographic success rate

    For radiographic evaluation, the treatment is rated as a failure when one or more of the following signs are present: furcation or periapical radiolucency, pathologic external root resorption, or internal resorption. The treatment is regarded successful if radiographic evaluation does not indicate any signs of failure.

    Measured: 6-month intervals, up to 2 years. From date of randomization until the date of first documented failure or up to 24 months

Questions about this trial

What is this clinical trial studying?

A study testing partial pulpotomy with biodentine and Formocresol pulpotomy in people with Pulpotomy and Tooth, Deciduous, run by Hadassah Medical Organization.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 14 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

partial pulpotomy clinical success rate (time frame: 6-month intervals, up to 2 years. From date of randomization until the date of first documented failure or up to 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2018.
