Direct pulp capping induces a local inflammatory process. Several biomaterials have been used for this procedure. The aim of this study was to compare the dentinal bridge thickness using three different pulp capping biomaterials with the conventional technique (high speed diamond bur) or Er-Yag laser, 1 month after pulp effraction. Materials and Methods: Forty two Class V cavities were prepared on the buccal surface of 4 maxillary incisors and 2 mandibular incisors of New Zealand rabbits. Specimens were divided into 6 treatment groups. Teeth were treated with: In Group 1: Er-Yag laser and Biodentine® (Septodont), in Group 2: Er: Yag laser and calcium hydroxide (Dycal® Dentsply), in Group 3: Er: Yag laser and adhesive system (Prime& Bond® NT Dentsply), in Group 4: high speed diamond bur and Biodentine® (Septodont), in Group 5: high speed diamond bur and calcium hydroxide (Dycal® Dentsply), and in Group 6: high speed diamond bur and adhesive system (Prime& Bond® NT Dentsply). The preparation was done with copious irrigation. The animals were sacrificed at 30 days and the teeth were extracted and prepared for histological analysis. Results: In the group of « laser Er-Yag », iatrogenic pulpal wounds treated with Biodentine® were covered with a thick hard tissue barrier after 1 month. The difference was not significant with the groups of Dycal® used with Er: Yag laser and high speed diamond bur. Prime& Bond® NT Dentsply specimens showed a thin dentinal bridge layer. Conclusion: At 1 month, Er-Yag laser proved to be useful with Biodentine® for direct pulp capping procedures.

Objective. This study presents a clinical and histological evaluation of human pulp tissue responses after direct capping using a new dentin adhesive system. Methods. Twenty-eight caries-free third molar teeth scheduled for extraction were evaluated. The pulps of 22 teeth were mechanically exposed and randomly assigned to 1 of 2 groups: Single Bond Universal or calcium hydroxide. Another group of 6 teeth acted as the intact control group. The periapical response was assayed, and a clinical examination was performed. The teeth were extracted after 6 weeks, and a histological analysis was performed. The pulp status was assessed, and the thickness of the dentin bridge was measured and categorized using a histological scoring system. Results. The clinical phase was asymptomatic for Single Bond Universal patients. Patients in the calcium hydroxide group reported mild symptoms of pain, although the histological examination revealed that dentin bridges with or without limited pulpitis had begun forming in each tooth. The universal adhesive system exhibited nonsignificantly increased histological signs of pulpitis (P>0.05) and a significantly weaker thin mineralized tissue layer (P<0.001) compared with the calcium hydroxide group. Conclusion. The results suggest that Single Bond Universal is inappropriate for human pulp capping; however, further long-term studies are needed to determine the biocompatibility of this agent.

The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 ?C. Mineral trioxide aggregate, bioactive dentin substitute or calcium-hydroxide paste were used as pulp capping materials. Cavities were restored with a light-cured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calcium-hydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5?C.

Reparative Dentin Formation

This study was performed to examine whether calcium silicate could induce reparative dentin formation without eliciting any adverse effect in direct pulp capping of premolar teeth. Twenty participants who need extraction of their 4 healthy permanent premolar teeth for orthodontic reasons were included in this study. Following the surgical procedure, the exposed pulp tissue was treated either with calcium silicate or covered with calcium hydroxide paste. On day 3, 7, 14 and 28, the experimental teeth was extracted and examined using light microscopy and histometric analysis to observe the inflammatory changes and the amount of reparative dentin formation. The results showed that in the calcium silicate treated teeth, substantial amounts of dentine-like tissue was formed on day 14 and mostly located on the exposure site. It was also observed in the calcium hydroxide treated teeth but dentin-like tissue located at a distance from the exposure site. The total amount of reparative dentine formed in the calcium silicate-treated teeth was significantly higher (p<0.005) than in the calcium hydroxide-treated specimens. In conclusion that the calcium silicate indices pulpal wound healing and reparative formation in the exposed teeth without affecting the normal function of the remaining pulp.

Study Materials

The aim: The research was to evaluate the effectiveness of acute traumatic pulpitis treatment with the use of bioceramics according to the results of a clinical study. Materials and methods: Acute traumatic pulpitis of 25 teeth in 25 patients aged 18-25 years were treated by biological direct pulp capping. In 13 patients of the main group, bioceramics was placed on the exposed pulp, and in 12 patients of the control group, calcium hydroxide paste was applied on the exposed pulp. Treatment effectiveness was evaluated according to the following criteria: the absence of clinical signs of pulpal inflammation, on X-ray – signs of dentinal bridge formation, the absence of periapical changes. Results: The use of bioceramic material in patients of the main group provided a positive dynamic of treatment in 12 teeth. The need for re-treatment was diagnosed only in 1 clinical case (7.7%), in the control group – in 4 cases (33.3%). Conclusions: Pulpitis treatment with the use of bioceramics provides preserving the functional properties of pulp, creation of a calcified barrier – dentin bridge and prevents the periodontal complications compared to the pulp capping with a material based on calcium hydroxide. The effectiveness of treatment in the main group was 92.3%, in the control – 66.7%.
