Full description
Rationale:
Pain caused by pulpitis is one of the most common reasons for emergency dental visits. The maintenance of the vitality of the dental pulp is one of the crucial targets of modern dentistry, based on the concept of minimally invasive dentistry. Preserving the vital pulp helps in retaining proprioceptive, reparative, tooth sensitivity (innervation), vascularization, and damping functions provided by vital pulp, which help in protecting against harmful stimuli. The traditional treatment modality for permanent mature teeth with irreversible pulpitis is nonsurgical root canal treatment (NSRCT) Moreover, these treatments are lengthy and costly, and are often subject to retreatment. Many biological and clinical studies have shown that the pulp of mature teeth, which is exposed due to carious lesions, is able to be heal, and that VPT should not be limited only to young or asymptomatic teeth. Therefore, a more conservative approach of VPT has been proposed for teeth with irreversible pulpitis. A favorable outcome of this approach depends on two factors: the healing ability of the remaining vital pulp and the biocompatibility of the pulp-capping agents used. Recent studies have observed success rates ranging from 82% to 95% using modern restorative materials in mature permanent teeth, thereby suggesting that pulpotomy can be a useful alternative to RCT in adults. Hydraulic calcium silicate cements (HCSCs) are recommended as the "gold standard" material for conservative treatment of the exposed pulp. MTA is one of the most commonly used and researched material for such purposes with successful clinical outcomes. However, due to certain inherent drawbacks of MTA, such as, extended setting time and tooth discolouration there is a need for the development of newer materials to overcome the challenges associated with MTA. TheraCal LC is a material that creates a new category of resin-modified calcium silicates. It displayed significantly higher calcium-releasing ability and lower solubility than either MTA or calcium hydroxide. This high calcium release has been shown to be critical for the stimulation of apatite formation and secondary dentin bridge formation while providing a mechanical seal of the pulp. TheraCal LC doesn't discolours tooth and also have ease in handling the material with fast setting time. Hence it is been currently used in this study as pulpotomy agent to evaluate the success rate.
Aim:
To evaluate and compare the clinical and radiographic success rate of TheraCal LC and MTA for coronal pulpotomy of mature permanent molars in 9-14 year children.
Objectives :
Materials and methods:
Setting: The study will be carried out in the Outpatient department of Pedodontics and Preventive Dentistry, PGIDS, Rohtak, Haryana.
Study Design: Randomized clinical study
Study Duration: This study shall be completed in a time span of 18 months.
Population: Children aged 9-14 years including both males and females diagnosed with deep carious lesion with irreversible pulpitis recruited from Outpatient department of Pedodontics and Preventive Dentistry, PGIDS, Rohtak, Haryana.
Sample size: Total number of 72 patients will be recruited in this study, with 36 patients allocated to each group
Methods: The children will be positioned supine on dental chair and examined by the dental examiners using dental chair light and mouth mirrors. Use of cotton pellets to dry the teeth and wipe away gross debris. The teeth will be anesthetized using lidocaine 2% with epinephrine 1:80000 and isolated with rubber dam. Access to the pulp chamber will be obtained after the removal of caries and exposure of the vital pulp, using a high speed bur with a water spray. Subsequently, the coronal pulp tissue will be removed down to the canal orifices. The pulp chamber will be irrigated with a light flow of water from the water syringe and excavated. A sterile cotton pellet damped in sterile saline will be placed against the pulp stumps at orifices of the root canals. The bleeding from pulp stump will be evaluated regarding the color and hemostasis achieved within 25 minutes of pressure application. After hemostasis, the test material will be placed as per the study groups.
Group 1- After hemorrhage control , 1-1.5mm of TheraCal LC will be placed on the radicular pulp stumps followed by light curing, followed by the placement of IRM cement and composite restorative material after 2 weeks following the evaluation of postoperative signs and symptoms.
Group 2- After hemorrhage control , a small ball like consistency of 2-3mm of MTA will be placed on the radicular pulp stumps, followed by the placement of IRM and composite restorative material after 2 weeks following the evaluation of postoperative signs and symptoms.
All procedures will be performed in one visit and periapical radiographs will be obtained immediately after treatment. Standardization of the X-ray will be done to have reproducibility of the X-ray during the follow-up period for evaluating the periapical changes post treatment.
Outcome measures: Clinically asymptomatic and no new periapical pathology is formed post treatment.
Statistical analysis: The data collected for each group will be entered in Microsoft excel chart to prepare a master chart. The statistical analysis for the study will be done using SPSS (Statistical Package for the Social Sciences, inc., United States). To assess the effect of independent variable on outcome variables chi square test or fischer test exact shall be utilised along with correlation and regression equation. Statistical significance will be computed and p value_< 0.05 will be considered significant.
