Comparative evaluation of effect of preoperative alprazolam and diclofenac potassium on the success of inferior alveolar, Vazirani-Akinosi, and Gow-Gates techniques for teeth with irreversible pulpitis: Randomized controlled trial.

Introduction: In teeth with irreversible pulpitis, successful local anesthesia is hard to achieve irrespective of the amount of local anesthesia and technique used. Such cases can be managed by concoction of pre-medications like anxiolytics, analgesics and effective local anesthesia. This double-blind, placebo-controlled study was planned to evaluate the effect of oral administration of alprazolam and diclofenac potassium on the success rate of inferior alveolar nerve block (IANB), Gow-Gates (GG) and Vazirani-Akinosi (VA) techniques for the root canal treatment of mandibular molars with irreversible pulpitis.

Mineral trioxide aggregate pulpotomy in autotransplanted immature mandibular third molar with a 4-year follow-up.

Autotransplantation is the surgical transposition of a tooth from its original site to another, replacing a lost or a compromised tooth by another tooth, usually the third molar in the same individual. This technique is considered a viable method due to its high success rate, well-grounded treatment option, provided the case selection and the procedure followed is within the acceptable limits. Autotransplantation is considered as an alternative approach of oral rehabilitations in a conservative manner mainly in young patients with compromised financial conditions to perform a high cost treatment.

Novel Matricing Technique for Management of Fractured Cusp Conundrum - A Clinician's Corner.

Longitudinal tooth fracture can be classified as craze lines, fractured cusp, cracked tooth, split tooth and vertical root fracture based on extent and severity of the fracture line. The most common type of longitudinal tooth fracture is fractured cusp that poses the treatment dilemma. Retention of the fractured cusp segment temporarily with matrix band followed by permanent bonded restoration and finally removal of tooth fragment during crown preparation is a novel technique.

Anaesthesia Techniques for Maxillary Molars - A Questionnaire-Based Retrospective Field Survey of Dentist in Western India.

Introduction: Clinicians use various anaesthesia techniques like Posterior Superior Alveolar (PSA) nerve block, buccal infiltration with or without supplemental anaesthesia like palatal and intraligamentary infiltrations for root canal treatment in maxillary molars. However there is no general consensus regarding which technique is enough for performing endodontic treatment in maxillary molars.

Aim: The aim of this questionnaire-based survey is to compare and evaluate the various techniques used to anaesthetize the maxillary molars and its effect on postoperative pain.

Conservative management of dens evaginatus and attached supernumerary tooth/odontome in mandibular premolar with dual radiolucencies.

Recently, an innovative, nonsurgical regenerative endodontic treatment protocol "SealBio" was introduced to manage mature nonvital permanent teeth with periapical lesions. This paper explains the management of an unusual case of dens evaginatus and an attached supernumerary tooth/an odontome associated with two distinct radiolucencies in a mandibular premolar with "SealBio" technique and discusses the various hypotheses on the pathogenesis of unusual malformation and associated pericervical cyst-like radiolucency in the involved tooth.

Karyotype, Pedigree and cone-beam computerized tomography analysis of a case of nonsyndromic pandental anomalies.

This case report presented a karyotype and pedigree analysis of a case with unusual combination of dental anomalies: Generalized short roots, talon cusps, dens invagination, low alveolar bone heights, very prominent cusp of carabelli and protostylid on first permanent molars, taurodontism of second permanent molars, rotated, missing and impacted teeth. None of the anomalies alone are rare. However, until date, nonsyndromic pandental anomalies that are affecting entire dentition with detailed karyotype, pedigree and cone-beam computerized tomography analysis have not been reported.

Endodontic management of maxillary first molar with type I canal configuration- a rare case report.

Thorough knowledge about the root canal variations is essential for the predictable endodontic treatment outcome. The root and root canal anatomy of maxillary first molar varies greatly. A Pub-med literature search about single rooted single canalled maxillary first molar was done to know its details such as incidence, diagnostic method used, age, sex and ethnic background of patient.

Autologus Platelet Rich Fibrin aided Revascularization of an immature, non-vital permanent tooth with apical periodontitis: A case report.

Caries or trauma induced non-vital immature permanent tooth with blunderbuss, thin root which are very common among childrens are corrected using regenerative endodontic (revascularization) procedures. In the presented case, a 16-year-old boy reported with chief complaint of pain in maxillary left central incisor (Tooth #21). Tooth #21 showed grade III mobility, draining labial sinus, and short blunderbuss root with diffuse periapical radiolucency.

Management of a rare combination of avulsion and intrusive luxation: A case report.

In traumatic dental injury, concomitant occurrence of avulsion and intrusive luxation is exceptional. This is because the vectors of forces responsible for both avulsive and intrusive injuries are in different directions. The present case report reviews the management of a rare combination of avulsion in right maxillary lateral incisor (tooth #12) and intrusive luxation in right maxillary central incisor (tooth #11) in a 22-year-old Asian male.

Endodontic management of a two rooted, three canaled mandibular canine with a fractured instrument.

It is important to assess the root canal morphology and its variations before initiating the endodontic procedure. This is because the inability to clean the complete root canal system forms the seat for the persistent infection which ultimately leads to endodontic treatment failure. This case reports the use of dental operating microscope for the successful endodontic management of a two rooted and three canaled mandibular canine with the fractured instrument in the middle canal of a 38-year-old healthy Asian woman.

Platelet-rich plasma supplemented revascularization of an immature tooth associated with a periapical lesion in a 40-year-old man.

The present case report is the first of its kind that documents the successful outcome of "revascularization," a regeneration-based treatment protocol in a mature adult patient. It belies the myth that "revascularization" should only be done in children and young, adolescent patients. The misconception that stem cells number as well as viability in older age group patients will not allow revascularization to be successful is also contradicted by this case.

Comparative outcome of revascularization in bilateral, non-vital, immature maxillary anterior teeth supplemented with or without platelet rich plasma: A case series.

Loss of pulp vitality in an immature permanent tooth arrests root development. This leads to tooth with open apex and weak lateral dentinal walls. Management of such necrotic teeth with immature roots poses several treatment challenges.
