Abstract
Apexification is a technique to generate a calcific barrier in a root with an open apex or the sustained apical development of an incomplete root in teeth with necrotic pulp. In contrast, apexogenesis describes the continued physiologic development and formation of the root’s apex in vital young permanent teeth. Apexification has been routinely practiced in immature teeth with necrotic pulp for many decades. This paper reviews the past and current concepts of management of immature permanent teeth. Introduction According to American Association of Endodontists-Apexification is defined as a method to induce a calcified barrier in a root with an open apex or the continued apical development of an incomplete root in teeth with necrotic pulp.1 The most widely used material until recently was calcium hydroxide that was replaced over intervals for several months, to stimulate calcific barrier formation. Torabinejad and Chivian (1993) introduced mineral trioxide aggregate (MTA) as an apical plug and now it is an accepted material for apexification till date.1 The use of calcium hydroxide affects various mechanical properties of radicular dentin. The alkaline pH of calcium hydroxide increases the chances of fracture due to denaturation of dentinal organic proteins. Hence, it is not recommended in teeth with thin dentinal walls. Mineral Trioxide Aggregate is a powder consisting of fine hydrophilic particles of tricalcium silicate, tricalcium aluminate, tricalcium oxide and silicate oxide. It also contains small amounts of other mineral oxides, which modify its chemical and physical properties. Radio opacity is provided by bismuth oxide.2 Compared to MTA, Biodentine handling is easy and needs much less time for setting. Unlike other Portland cement-based products, it is sufficiently stable so that it can be used both for pulp protection and temporary fillings.3
