Clinical Evaluation and Cone Beam Computed Tomography Analysis of Amniotic Membrane, Putty Mineral Trioxide Aggregate and Biodentine as Therapeutic Agents for Apexogenesis of Immature Permanent Molars: A Randomized Clinical Trial
The present study will be conducted to clinically evaluation and cone beam computed tomography analysis of amniotic membrane, putty mineral trioxide aggregate and biodentine as therapeutic agents for apexogenesis of immature permanent molars
An immature permanent tooth is defined as, a newly erupted permanent tooth with incomplete root apex formation. Since root development is completed in 2-3 years after tooth eruption into the oral cavity, loss of pulp vitality in the immature permanent tooth affected by caries, traumatic injury, or other causes creates major problems. The primary goal of pulp therapy is to maintain the integrity of the teeth while maintaining the vitality of the pulp, especially in young permanent teeth with immature roots to enhance root dentin formation. An increasingly popular therapy option for pulp damage in immature permanent molars is apexogenesis. Vital pulp therapy involves the complete removal of the coronal pulp and the placement of an acceptable material into the pulp chamber. With the invention of calcium silicate material namely mineral trioxide aggregate (MTA), it became preferred to calcium hydroxide in the treatment of exposed pulp. MTA demonstrated excellent biocompatibility, low solubility, outstanding sealing properties and antibacterial effect. However, MTA has some limitations regarding the long setting time and difficult handling. Premixed calcium silicate cements were developed to facilitate manipulation with no need for mixing, such as using the putty formulation which allows better handling with a thicker consistency Additionally, Biodentine was introduced as a tricalcium silicate-based bioceramic, with comparable physical properties to dentine, thus, it is also called dentine replacement material and has applications like those of MTA. Considering the limitations of MTA, biodentine has been developed with enhanced physicochemical properties such as a fast-setting time with an initial setting time between 9 and 12 minutes due to the presence of calcium chloride. Its short setting time allows restoration to be made in one session with easier chairside handling than MTA. Recently, novel biologically based material has been developed from the innermost layer of the placenta with highly rich stem cell reservoirs and is called amniotic membrane. The amniotic membrane is rich in growth factors, various types of collagens (such as types I, III, IV, V, and VII), along with proteoglycans, elastin and hyaluronic acid. It possesses a range of beneficial properties, including anti-inflammatory, antimicrobial and analgesic which make it a unique option for wound healing, providing a supportive environment that promotes the survival and proliferation of mesenchymal progenitor cells. In dentistry, researchers supported its application in regenerative endodontic therapy by providing a growth factors that promote stem cell growth and formation of a new dentine-pulp complex. Therefore, in the present study, clinical and radiographic evaluation will be done to assess the effectiveness of different biomaterials in managing immature permanent tooth with pulp exposure.
