A preliminary report on histological outcome of pulpotomy with endodontic biomaterials vs calcium hydroxide.

Nosrat A, Peimani A, Asgary S - Restor Dent Endod (2013)

Bottom Line: 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.In contrast, the human dental pulp response to CH might be unpredictable.

ABSTRACT

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.

Figure 3: Necrotic radicular pulp in one of the teeth after pulpotomy with calcium hydroxide (CH). Note the resorptive lacunas on root canal dentinal walls.

Mentions: CH group: Vital pulp was seen in two teeth (Figure 2). One two rooted tooth (the same tooth shown in Figure 1), had necrotic pulp in all roots/sections; resorptive lacunas were seen in roots with necrotic pulp (Figure 3). A continuous calcified bridge was seen in all roots with vital pulp. There was no inflammation in roots with vital pulps (Figure 2). No evidence of odontoblast-like cells was found beneath CH in two roots with vital pulps. Diffuse calcification could be seen in one tooth (two roots).
