Introduction: Conservative pulp therapy is an approach to maintain pulp vitality. Direct pulp capping and Partial Pulpotomy are two main approaches of this therapy. The aim of this study was histological comparison of direct pulp capping and Partial Pulpotomy with MTA in human premolar teeth.Materials& Methods: In this randomized clinical trial, 40 healthy premolar teeth were selected from patients who needed tooth extraction because of orthodontic treatment. After anesthesia, isolation and preparation of a Cl I cavity on the occlusal surface, an exposure was made in the buccal pulp horn using a #½ round bur with the whole bur entering the pulp chamber in half of the samples. In the remaining samples, a small exposure was made in the buccal pulp horn. The pulps in both groups were sealed with MTA (PRO Root, Dentsply, Switzerland). All the cavities were restored with glass-ionomer. After 60 days, all the teeth were extracted and after fixation and decalcification processes, 4-μ sections were obtained. H& E staining was carried out. The sections were analyzed by an oral pathologist who was blinded to the study procedures. Data were analyzed with Kruskal–Wallis test and Fisher's exact test (a<0.05).Results: There were no significant differences between direct pulp capping and Partial Pulpotomy in pulp reaction (p value=0.823). The calcified bridges formed were not significantly different between the two groups (p value=0.985).Conclusion: Direct pulp capping and Partial Pulpotomy are both useful for maintaining pulp vitality.

This report describes a case of a 7 years old girl who suffered from complicated crown fracture of right mandibular central incisor because of a bicycle accident. For the tooth Partial Pulpotomy with calcium hydroxide, capping was performed in order to achieve apexogenesis and the tooth was restored with a double-seal of glass ionomer cement and composite resin. The patient was reviewed over 8 years. The tooth showed continued root development and complete apex formation.

Vitality of dental pulp is essential for long-term tooth survival. The aim of vital pulp therapy is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. There are several different treatment options for vital pulp therapy in extensively decayed or traumatized teeth. Pulp capping or Pulpotomy procedures rely upon an accurate assessment of the pulp status, and careful management of the remaining pulp tissue. The purpose of this review is to provide an overview of new approaches in vital pulp therapy in permanent teeth.

Dentists always prioritize the preservation of the dental pulp. Nowadays, minimally invasive endodontic techniques such as Vital Pulp Therapy (VPT) are considered due to their affordability and remarkable success compared to conventional treatments such as Root Canal Treatment (RCT). VPT aims at preserving healthy portions of the exposed pulp while removing the inflamed parts with biocompatible materials to seal the pulp. The present case report aimed to describe a successful VPT of a right mandibular permanent first molar with reversible pulpitis using Calcium Enriched Mixture (CEM) cement in an 18-year-old female patient. As pulp exposure happened regarding extensive caries removal, 2 mm of the inflamed pulp was removed and replaced with CEM cement. CEM was covered with Resin-modified glass ionomers (RMGI) and the tooth was restored with amalgam. Regular follow-ups were performed at 3 and 6 months and 1, 2, and 4 years after treatment. Conclusion: The tooth was clinically and radiographically functional without signs and symptoms of infection or inflammation. The result of this case suggests that pinpoint pulp exposure during deep caries excavation can be successfully treated with VPT using CEM cement.
