Effect of Pulpotomy Using TheraCal Versus MTA on Survival Rate of Cariously-Exposed Vital Permanent Molars

Not Applicable

Completed

• Conditions: Caries, Dental
• Interventions: Drug: TheraCal; Drug: MTA-Anglus

• Registration Number: NCT03119779
• Lead Sponsor: Cairo University

Brief Summary

Objective:

To assess which is the most efficient pulpotomy medicament on tooth survival in patients with a cariously-exposed vital young permanent molar regarding: absence of postoperative pain, sinus or swelling, internal/ external root resorption, periapical radiolucency), root maturation and decrease chair side time of treated patient.

Trial design Randomized Clinical Trial (RCT), double-blinded with parallel group and allocation ratio (1:1), equivalence framework.

Detailed Description

Preoperative records will be taken (photos, conventional periapical radiographs, and impression to construct acrylic stent to help standardization on follow up apical radiographs). Administration of inferior alveolar nerve block then using rubber dam isolation one of the investigators will remove the caries using large round but under copious amount of coolant and if carious exposure occur, part of the pulp chamber will be removed using sharp spoon excavator. Then the pulp status will be assessed if bleeding is controlled with direct irrigation with distilled water for 2 minutes then next step will be taken but if not continue excavation of the pulp till bleeding is controlled. if bleeding is not controlled after performing complete pulpotomy, tooth will be excluded from the study Then direct application of capping materials (TheraCal or MTA) according to manufacturer instructions, then Riva self-cure glass-ionomer base and composite resin final restoration. One of the investigators will take immediate standardized postoperative periapical radiographs. Follow-up will be for 12 months. Pre-calibrated blinded dentists will assess out comes separately.

Arm && Interventions

Group	Intervention	Description
TheraCal vital pulp therapy	TheraCal	Using rubber dam isolation we will remove the caries using large round but under copious amount of coolant and if carious exposure occur, part of the pulp chamber will be removed using sharp spoon excavator. After complete removal of the caries and control of bleeding, then direct application of incremental layers of TheraCal using the tip of the syringe container of the material and each layer should not exceed 1 mm then light curing each increment. Then Riva self-cure glass-ionomer base and composite resin final restoration. We will take immediate standardized postoperative periapical radiographs.
MTA vital pulp therapy	MTA-Anglus	Using rubber dam isolation we will remove the caries using large round but under copious amount of coolant and if carious exposure occur, part of the pulp chamber will be removed using sharp spoon excavator. After complete removal of the caries and control of bleeding, then direct application of freshly mixed MTA-Anglus on sterile glass slap. MTA application then gentle condensation over wet cotton till MTA thickness is about 2-3 mm thickness and removal of excess material from walls of pulp chamber. Application of wet cotton for 15 min. to achieve initial setting of MTA. Then Riva self-cure glass-ionomer base and composite resin final restoration. We will take immediate standardized postoperative periapical radiographs.
