Clinical and Radiographic Assessment of Neo Putty MTA Versus Formocresol Used in Vital Pulpotomy of Mandibular Primary Molars

February 23, 2026 updated by: Ahmed Shawky Amer, October University for Modern Sciences and Arts

Clinical and Radiographic Assessment of Neo Putty MTA Versus Formocresol Used in Vital Pulpotomy of Mandibular Primary Molars: A Randomized Clinical Trial

This randomized clinical trial aims to evaluate the clinical and radiographic success of NeoPutty MTA compared to formocresol in vital pulpotomy of mandibular primary molars in children aged 4 to 9 years. Participants will be randomly allocated into two groups (1:1) to receive pulpotomy using either NeoPutty MTA or formocresol, followed by restoration with stainless steel crowns. Clinical and radiographic outcomes will be assessed during follow-up visits.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Pulpotomy is a commonly performed vital pulp therapy in pediatric dentistry. Formocresol has been widely used due to its high clinical success; however, concerns exist regarding its potential toxicity. NeoPutty MTA is a premixed bioceramic material introduced as an alternative pulpotomy agent with improved handling properties and bioactivity. This randomized parallel-group clinical trial will compare NeoPutty MTA versus formocresol in vital pulpotomy of mandibular primary molars. Children aged 4-9 years presenting with asymptomatic carious mandibular primary molars will be recruited from the Pediatric Dentistry Department, Faculty of Dentistry, MSA University. Eligible teeth will undergo standardized pulpotomy procedures, restoration with glass ionomer cement, and stainless steel crowns. Clinical and radiographic follow-up will be performed at scheduled intervals to evaluate success and failure outcomes.

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

  • Child

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

Children with asymptomatic decayed primary mandibular molar(s).

  • Patient and parent showing cooperation and compliance.
  • Children 4-9 years old.
  • Vital carious primary(s) with complete root formation.
  • Asymptomatic teeth or without clinical symptoms of spontaneous pain.
  • No clinical evidence of pulp degeneration like the history of spontaneous or nocturnal pain, tenderness to percussion, pathologic tooth mobility, swelling, or fistulous tract.
  • Both genders will be included.
  • No radiographic evidence of pulp degeneration such as internal root resorption, external root resorption, or furcal radiolucency.
  • Presence of two thirds of the root.
  • Teeth that can be restored.
  • Children with prior parental consent.

Exclusion Criteria:

  • History of any systemic disease.
  • Hemostasis is not achieved within 5 minutes of pulp amputation, by direct contact with a wet cotton pellet before the material placement.
  • The remaining radicular tissue was non-vital (with suppuration or purulence necrosis).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Arm A: NeoPutty MTA Pulpotomy
Participants will receive vital pulpotomy of mandibular primary molars using NeoPutty MTA as the pulpotomy medicament, followed by restoration with glass ionomer cement and stainless steel crown.
Drug: NeoPutty MTA
NeoPutty MTA (NuSmile) will be placed directly over the radicular pulp stumps after hemostasis, then the tooth will be sealed with resin-modified glass ionomer cement and restored with stainless steel crown.
Active Comparator: Arm B: Formocresol Pulpotomy
Participants will receive vital pulpotomy of mandibular primary molars using formocresol (1:5 dilution of Buckley's formocresol) applied with cotton pellet, followed by reinforced zinc oxide eugenol, glass ionomer cement, and stainless steel crown.
Drug: Formocresol
A sterile cotton pellet lightly moistened with a 1:5 dilution of Buckley's formocresol will be placed against the pulp stumps for 3-5 minutes, then removed. Reinforced zinc oxide eugenol will be placed, followed by glass ionomer cement and stainless steel crown restoration.

What is the study measuring?

Primary 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.
