10.1 Introduction

Bioceramic‐based materials have a long history of use in tissue regeneration and medicine [1]. They were introduced to dentistry, specifically endodontics, as root and perforation repair materials or sealers [2–4]. Bioceramics consist of nanosphere particles, with the maximum dimension not exceeding 1 × 10⁻³ μm [2], and mainly composed of tricalcium silicate, dicalcium silicate, calcium phosphate monobasic, amorphous silicon dioxide, and tantalum pentoxide [5]. Owing to their ability to penetrate dentinal tubules and to interact with dentine moisture, an optimum dimensional stability, and the least amount of shrinkage can be expected. When compared to white MTA, bioceramics have the advantage of being aluminum‐free and inclusion of tantalum pentoxide as an opacifier [6].

Historically, Ca(OH)₂ medicament has been used for partial pulpotomy of the necrotic immature permanent tooth [7]. Bioceramics with an alkaline pH of 12.8 demonstrating effective antibacterial activity are becoming popular for the same clinical use [4].

The present clinical case report aims to present a similar case where bioceramic material has been used to manage a deep carious lesion leading to exposure of the pulp.
