  • Objectives: The purpose of the study was to evaluate human dental pulp response to pulpotomy with calcium hydroxide (CH), mineral trioxide aggregate (MTA), and calcium enriched mixture (CEM) cement. Materials and Methods: A total of nine erupted third molars were randomly assigned to each pulpotomy group. The same clinician performed full pulpotomies and coronal restorations. The patients were followed clinically for six months; the teeth were then extracted and prepared for histological assessments. The samples were blindly assessed by an independent observer for pulp vitality, pulp inflammation, and calcified bridge formation. Results: All patients were free of clinical signs/symptoms of pulpal/periradicular diseases during the follow up period. In CH group, one tooth had necrotic radicular pulp; other two teeth in this group had vital uninflamed pulps with complete dentinal bridge formation. In CEM cement and MTA groups all teeth had vital uninflamed radicular pulps. A complete dentinal bridge was formed beneath CEM cement and MTA in all roots. Odontoblast-like cells were present beneath CEM cement and MTA in all samples. Conclusions: This study revealed that CEM cement and MTA were reliable endodontic biomaterials in full pulpotomy treatment. In contrast, the human dental pulp response to CH might be unpredictable.

  • Objectives: The purpose of this study was to critically evaluate the quality, reliability and educational content of the information of vital pulp treatment videos available on YouTube. Materials and Methods: The keywords "pulpotomy" and "pulp capping" were searched on YouTube on 5th July 2020, until 60 English language videos of each search term with a duration shorter than 15 minutes were acquired. Video characteristics were recorded and Video Power Index (VPI) was calculated. Reliability and educational quality of videos were evaluated using the Modified DISCERN score, the Journal of American Medical Association (JAMA) benchmark criteria and Global Quality Scores (GQS). Videos were categorized by uploading source. Results: Regarding pulpotomy, 31.7% of the videos were uploaded by specialists and 68.3% were directed by non-specialists. In the case of pulp capping, the corresponding percentages were 45% and 55%, respectively. Videos uploaded by specialists had significantly higher modified DISCERN, JAMA and GQS scores compared to those uploaded by non-specialists. Endodontists tended to have the highest reliability and VPI scores. Conclusions: YouTube videos on vital pulp treatment contain low educational quality or incomplete information. Low popularity of dental pulp capping and pulpotomy videos may be attributed to the specialized nature of these procedures. As YouTube represents an important source for patient information about different health topics, reliable informative videos should be uploaded by specialized dental professionals.

  • Two cases of vital pulpotomy for treatment of open fractured canine teeth in dog were referred to the Veterinary Teaching Hospital of College of Veterinary Medicine, Chonnam National University. In case 1, a 2-year-old male Locker. Spaniel was fractured left mandibular canine and the pulp was exposed. In case 2, an 1-year-old male Border Collie was open fractured both mandibular canine teeth. In both cases, we made sure of pulp vitality by oral examination and radiological findings. Therefore, we performed vital pulpotomy in these patients. Two months after therapy, radiological examinations were performed for evaluation of success of therapy. In both cases the radiographs showed normal periapical anatomy and no changes in the root resorption.

  • To compare the effects of various pulp capping agents that are usually applied to human pulp tissue, adult dogs were bred for a certain period and each capping agent was applied experimentally to pulp tissue after vital pulpotomy. Histological observations are as follows. 1) In comparison between methods of vital pulpotomy, one and two appointment method, different courses of healing were observed. In one appointment method, the granulation tissue formation at the amputation sur face of pulp tissue had a tendency to be transformed to scar tissue formation. In two appointment method, more transformation than that of one appointment method from scar tissue to dentin matrix formation were observed. 2) Histologic changes that have appeared in pulp tissue are a) fixation at outer layer b) degeneration at middle layer c) hyperemia and round cell infiltration at inner layer 3) With use of formocresol mixed zinc oxide powder in two appointment method complete formation of dentin matrix were observed. 4) Among the methods and aagents described above formocresol mixed zinc oxide powder in two appointment method appeared to be relatively effective.

  • Objectives: This study aimed to compare the postoperative pain and clinical performance after partial pulpotomy by using ProRoot MTA and Endocem MTA. Materials and Methods: Twenty-eight teeth requiring partial pulpotomy due to deep dental caries or traumatic injury were included in this study. After 2mm removal of exposed pulp and bleeding control, the ProRoot MTA or Endocem MTA was randomly adjusted to the exposed site. 1, 2, 4, and 12 weeks after the final restoration, the patients were recalled to check the postoperative pain or another unfavorable signs. Pearson's chi-square test was used for statistical analysis to evaluate any differences among tested materials. Results: 3 of 28 teeth showed postoperative pain and cold positive during follow-up period (10.7%). There were no statistically differences in pain occurrence between two tested materials (P > 0.05). Conclusions: In the limitations of this study, partial pulpotomy by using Endocem MTA showed the advantages of short setting time and lower postoperative pain incidence, allowing one visit treatment.

  • Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. Pulpotomy is a vital pulp therapy in which a portion of the coronal pulp tissue is surgically removed, and the remaining radicular tissue is covered with suitable material that protects the pulp from further injury and permits and promotes healing. It is important to develop biocompatible treatment directed at maintaining pulp vitality and increasing tooth longevity. Platelet-rich fibrin (PRF) has been referred to as a second-generation platelet concentrate. Two clinical cases in which PRF was applied as a medicament after pulpotomy of an immature permanent tooth are presented. After isolation, caries removal and pulpotomy with PRF was performed. A layer of mineral trioxide aggregate (MTA) was placed over the PRF, and the final restoration was performed. Postoperatively, the patient had no pain or discomfort, and follow-up radiographs revealed normal periodontal ligament space and trabecular bone pattern.

  • Objectives: The purpose of this study was to evaluate the efficacy of mineral trioxide aggregate (MTA), Biodentine and Propolis as pulpotomy medicaments in primary dentition, both clinically and radiographically. Materials and Methods: A total of 75 healthy 3 to 10 yr old children each having at least one carious primary molar tooth were selected. Random assignment of the pulpotomy medicaments was done as follows: Group I, MTA; Group II, Biodentine; Group III, Propolis. All the pulpotomized teeth were evaluated at 3, 6, and 9 mon clinically and radiographically, based on the scoring criteria system. Results: The clinical success rates were found to be similar among the three groups at 3 and 6 mon where as a significant decrease in success rate was observed in Group III (84%) compared to both Group I (100%) and Group II (100%) at 9 mon. Radiographic success rates over a period of 9 mon in Groups I, II, and III were 92, 80, and 72%, respectively. Conclusions: Teeth treated with MTA and Biodentine showed more favorable clinical and radiographic success as compared to Propolis at 9 mon follow-up.

  • Fracture of the crown in a permanent incisor is relatively common. When it occurs with pulp exposure, it presents both restorative and endodontic problems. In the restoration of a fractured incisor, reattachment of the original fragment or restoration with a composite resin is preferred over a temporary crown. If fractured fragment is intact, the tooth can be restored with reattachment of the fragment. An exposed pulp in a young crown-fractured incisor is usually treated with either pulp capping or pulpotomy depending on the size of an exposure and time elapsed since injury. However, in teeth showing vital and/or hyperplastic pulp tissue at the exposure, only superficial layers of the pulp and surrounding dentin should be removed : i.e. partial pulpotomy can be performed in immature as well as mature teeth. This paper reports 2 cases of crown-fractured permanent incisors with pulp exposure that had been treated by reattachment of original fragment followed by partial pulpotomy or partial pulpectomy. The following results are obtained. ; 1. Fragment reattachment is an acceptable semi-permanent restoration of crown fractured young permanent incisor. 2. Partial pulpotomy is recommended as the treatment of choice in crown-fractured permanent teeth with pulp exposure.

  • Pulpotomy is a frequently used treatment modality in primary teeth. It is method by which infected coronal pulp is removed while retaining vital radicular pulp. Since its introduction in 1930 by Sweet formocresol remains the most popular medicament for this treatment. However, despite its outstanding bactericidal properties, formocresol is known to cause adverse tissue reactions. Theoretically, formocresol disinfects and fixes radicular pulp and thus prevents infection and internal resorption. In reality, however, it leads to chronic inflammation and is sometimes responsible for failures through abscess formation and internal root resorption. Also, Myers et al., in 1978, reported on the systemic distribution of FC and other studies have followed with reports of its immunological, mutagenic and carcinogenic effects. Much effort has, therefore, focused on the development of alternative medicaments and techniques. Since its introduction in 19C, ferric sulfate proven itself as an effective hemostatic agent and is used as an astringent in dentistry. In 1988, Landau and Johnsen suggested ferric sulfate be used as a medicament in pulpotomy and many studies have focused on it to overcome the toxic effects of FC. Ferric sulfate acts through its ferric ion and iron ion, which react with blood protein leading to aggregation. The aggregated protein acts to plug the blood vessels, causing mechanical hemostasis. As blood clot formation is minimal, there is reduced inflammation of radicular pulp and enhanced healing. There are no reports regarding its systemic distribution. This is a report of cases treated by the author using pulpotomy with ferric sulfate.
