Dentinal Adaptation of Warm Thermoplastic Obturating Material and Cold Thermoplastic Obturating Material: An Study.

Introduction: The objective of endodontic obturation is to provide a complete seal along the length of the root canal system, thereby ensuring the healing and sustained health of the periradicular tissue. Root canal obturation involves the three-dimensional filling of the entire root canal system and is a critical step in endodontic therapy. Gutta-percha has universally been accepted as the gold standard for root canal filling materials.

After scrutinizing the database, CBCT of 40 males and 40 females that conformed to the inclusion and exclusion criteria were selected for the study.

Accidental injection of 2% chlorhexidine gluconate instead of an anesthetic agent: A case report.

We report a case where 2% chlorhexidine (CHX) gluconate was mistaken for an anesthetic solution and infiltrated into the buccal vestibule during routine root canal treatment. Accidentally, 2% CHX gluconate solution was injected in the right upper buccal vestibule (16) of a 23-year-old male during routine root canal treatment. The patient experienced pain and a burning sensation over the injected area shortly after injection.

Effect of post space preparation on the sealing ability of mineral trioxide aggregate and Gutta-percha: A bacterial leakage study.

Use of second-generation platelet concentrate (platelet-rich fibrin) and hydroxyapatite in the management of large periapical inflammatory lesion: a computed tomography scan analysis.

Periapical surgery is required when periradicular pathosis associated with endodontically treated teeth cannot be resolved by nonsurgical root canal therapy (retreatment), or when retreatment was unsuccessful, not feasible or contraindicated. Endodontic failures can occur when irritants remain within the confines of the root canal, or when an extraradicular infection cannot be eradicated by orthograde root canal treatment. Foreign-body responses toward filling materials, toward cholesterol crystals or radicular cysts, might prevent complete periapical healing.

Use of platelet-rich fibrin as an autologous biologic rejuvenating media for avulsed teeth - an in vitro study.

Aim: The prognosis of replanted avulsed tooth depends on the existence of viable cells in the periodontal ligament and also on those cells which are able to proliferate on the damaged areas of the root. The purpose of this study was to evaluate the survival of periodontal ligament cells (PDL) when soaked in an autologous biologic rejuvenating media after an extra-oral dry time of 40 min.

Method: Thirty teeth were selected with intact crown which were advised for Orthodontic extraction having healthy PDL.

Successful removal of a 16 mm long pulp stone using ultrasonic tips from maxillary left first molar and its endodontic management.

To present a case report describing successful removal of a 16 mm long pulp stone in a single mass from a maxillary left first molar and its endodontic management. In the presented case, the conventional approach of dissecting the pulp stone was not considered, as radiographically the calcification was extending up to the apex of the palatal root canal and the separation of the coronal and radicular pulp stone would have risked the obliteration of its orifice. A new set of ultrasonic endodontic tips were used for the removal of significantly large pulp stone in single mass.

A comparative evaluation of fracture resistance of endodontically treated teeth, with variable marginal ridge thicknesses, restored with composite resin and composite resin reinforced with Ribbond: an in vitro study.

Background: The anatomic shape of maxillary premolars show a tendency towards separation of their cusps during mastication after endodontic treatment. Preservation of the marginal ridge of endodontically treated and restored premolars can act as a strengthening factor and improve the fracture resistance.

Objectives: To evaluate the effect of varying thickness of marginal ridge on the fracture resistance of endodontically treated maxillary premolars restored with composite and Ribbond reinforced composites.

Use of ribbond and panavia F cement in reattaching fractured tooth fragments of vital maxillary anterior teeth.

Coronal fractures of the anterior teeth are a common form of dental trauma that mainly affects children and adolescents. One of the options for managing coronal tooth fractures when the tooth fragment is available and there is no or minimal violation of the biological width is the reattachment of the fragment. This article presents a novel technique for reattachment of oblique fractured fragment of vital maxillary central and lateral incisor with pulp exposure.

Single-step apical barrier placement in immature teeth using mineral trioxide aggregate and management of periapical inflammatory lesion using platelet-rich plasma and hydroxyapatite.

We present here a case report of a tooth with an immature root with a large periapical lesion. The open apex was managed by placing an apical barrier using mineral trioxide aggregate, and the periapical lesion was treated surgically. A combination of platelet-rich plasma (PRP) and hydroxyapatite graft (HA) was used to achieve faster healing of the periapical lesion.

Invasive cervical resorption: a case report.

Invasive cervical resorption (ICR) is a relatively uncommon form of external resorption, which may occur in any tooth in the permanent dentition. Characterized by its cervical location and invasive nature, this resorptive process leads to progressive and usually destructive loss of the tooth structure, the clinical features of which often resemble internal resorption ("pink tooth"). This article describes a case report of ICR and its management.
