The resin-dentin interface of in vivo specimens restored with the All-Bond 2 system by use of a total-etch wetbonding technique on vital deep human dentin was investigated by: (a) SEM examination of cryofractured specimens; (b) SEM examination of acid-rinsed, highly polished, embedded specimens; and (c) TEM examination of demineralized ultrathin sections. Ultrastructural features that were pert...

AIM To present a case report in which the pulp of two bilateral mandibular premolars with dens evaginatus were revascularized using a modified novel technique to avoid undesired crown discolouration. SUMMARY Recently, regeneration of necrotic pulps has become an alternative conservative treatment option for young permanent teeth with immature roots and is a subject of great interest in the fi...

introduction: thermal changes in laser assisted root canal therapy with the use of diode laser can predispose tooth structure to the fracture. this study evaluated the changes in flexural strength of dentin blocks after diode laser irradiations (810 nm). methods: a total of 60 dentinal blocks were prepared from freshly extracted teeth in three different thicknesses (300, 500 and 1000μm) and 20 ...

Non vital immature teeth with open apex and thin dentinal walls are difficult to treat via conventional endodontic therapy. Calcium hydroxide has been conventionally used in such cases for a long time. However, due to its various shortcomings, MTA (Mineral Trioxide Aggregate) became the material of choice. A new bioactive dentin replacement material, Biodentine, can act as an ideal dentin subst...

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open a...

Inflammatory lesions in the periapical tissues of the teeth are a result of root canal infection following partial or complete breakdown of the pulp. Infected root canals have a complex microbial flora consisting of cocci, rods, spirochaetes, filaments and fungi which may exist as a loose collection in mist canal lumen or as dense aggregates (biofilms) adhered to dentinal walls. The biofilm env...
