 Abstract

The success of endodontic therapy depends on achieving three-dimensional obturation of the root canal system by forming a hermetic seal that blocks all portals of entry between the tooth and the periodontium. Obturation is achieved mainly through two components: a root canal sealer and a core filling obturation material. As most of the core filling materials used today are non-adhesive, it is the root canal sealer that plays an important role in achieving an airtight seal throughout the canal, including the apical foramen, canal irregularities, and minor discrepancies between the dentinal wall of the canal and the core. The advent of MTA-based sealers, a tricalcium silicate-based cement, has provided a new category of sealers with superior sealing ability and biocompatibility, thereby providing a biological seal. This review article will shed light on the evolution of MTA-based sealers and their revolutionary applications in endodontic therapy. ...Read More >>

 Pre-Fabricated Chair side Conservative Bridge

  

  R. Mensudar , A. Karthick , D. Amudha

 Abstract

The development of glass fibers and reinforced composite technology has created a new era in metal-free adhesive dentistry. Conservative bridges can be fabricated by acid etching enamel and bonding a pontic to adjacent natural tooth structure. These bridges are a viable alternative to conventional fixed bridges, especially where the edentulous space is no wider than one or two teeth. This article describes in detail the construction of conservative bridges using glass fibers with case report. ...Read More >>

 A Modified Lab Technique for Hollow Complete Denture Obturator

 Abstract

Maxillectomy patients have a compromised maxillary denture-bearing area, which may lead to problems in rehabilitation. This can be due to a narrow, more constricted residual ridge, as well as a large defect. As a result, a heavy prosthesis compounded with poor denture-bearing ability of the tissues and reduced prosthesis retention can occur. However, reducing the weight of the maxillary prosthesis has been shown to be beneficial when constructing an obturator for the restoration of a large maxillofacial defect. Various techniques are reported in the literature. This article describes a modified technique for fabricating a hollow maxillary complete denture obturator. ...Read More >>

 Bite Marks in Forensic Odontology – A Reliable Clue in Crime Investigation?

  

  R. Hemalatha , S. Vishnu Prasad , P. Sampath Kumar

 Abstract

Forensic dentistry or Forensic Odontology involves the proper handling, examination, and evaluation of dental evidence, which is then presented in the interest of justice. Bite marks in crimes against persons are patterned injuries produced by the teeth, which can be extremely helpful in identifying the biter. The widely accepted premise is that the human dentition is unique to each individual. The function of the forensic odontologist is to attempt to collect, preserve, and analyze the bite mark evidence. If bite marks are properly preserved and protected, they can provide an important link between the victim and assailant. ...Read More >>
