Abstract
Summary
The study was designed to evaluate and compare the success rates of two types of vital pulp therapies in a group of β-thalassemic children who were sixty five in number with an age range of 4-7 years old fulfilling the preoperative clinical and radiographic criteria for vital pulp therapy having clinically deep carious primary molars that are diagnosed from the clinical history with reversible pulpitis with no soft tissue swelling, sinus or fistula and restorable with a filling or crown.
The radiographic inclusion criteria were absence of periapical or furcation involvement, absence of widening of periodontal ligament space and no internal or external pathological root resorption. Non-vital teeth, symptomatic teeth with preoperative spontaneous pain and persistent pain and bleeding after hemostasis during pulpotomy were excluded from the study. Also, children who were unwilling to participate and those who could not continue the treatment or follow up were not included in the study.
The blood picture with proper hemoglobin levels were checked before starting any dental procedure and dental treatment was carried out after blood transfusion. Preoperative intraoral photographs as well as preoperative periapical radiographs were taken prior to treatment after explaining the steps of the study clearly with the patients and after obtaining their informed consent and assent.
The children were randomly allocated into two main groups where group I is MTA pulpotomy and group II is indirect pulp capping. The two main groups were then sub-divided into two sub-groups receiving either stainless steel crowns or high viscosity glass ionomer cement as final restorations.
The clinical and radiographic evaluation criteria and follow ups were according to the guidelines of the AAPD of no pain or soft tissue swelling or tenderness to percussion, or tooth mobility clinically and with the absence of periapical or furcation involvement, the absence of widening of periodontal ligament space and the absence of pathological internal or external pathological root resorption radiographically were used at baseline, six months and one year.
Data were collected and entered to the Statistical Package for Social Sciences. Quantitative data were presented as mean, standard deviation and range when parametric and qualitative variables were presented as numbers and percentages. Comparison between groups with qualitative data was done using Chi-square test. The confidence interval was set to 95% and the p-value was considered to be significant when p-value is less than 0.05 and non-significant when p-value is more than 0.05.
The results showed that both types of vital pulp therapies were successful with no statistical significant difference between them and can be finally restored with either stainless steel crowns or high viscosity glass ionomer restorations successfully without statistical significant difference in the success rate between the two types of restorations. In conclusion, both types of vital pulp therapies can be used safely and effectively in β-thalassemic children.
