Management of a Previously Treated, Calcified, and Dilacerated Maxillary Lateral Incisor: A Combined Nonsurgical/Surgical Approach Assisted by Cone-beam Computed Tomography.

Teeth with calcified canals, dilacerated roots, and associated large periradicular lesions involving both cortical plates pose a challenge to dentists. In addition to the nonsurgical endodontic treatment, such teeth may require surgical intervention with concomitant use of bone grafting materials and barrier techniques. These techniques, when combined with the use of a host modulating agent such as platelet-rich fibrin (PRF), may improve the chances of success.

Microorganisms in periradicular tissues: Do they exist? A perennial controversy.

There is no greater association between the basic science and the practice of endodontics than that of microbiology. One of the strongest factors contributing to the controversies often encountered in the endodontic field is the lack of understanding that the disease processes of the pulp and periradicular tissues generally have a microbiological etiology. The vast majority of diseases of dental pulp and periradicular tissues are associated with microorganisms.

Pulp Revascularization- It's your Future Whether you Know it or Not?

Pulpal regeneration after tooth injury is not easy to accomplish. In teeth with immature apices and exposed vital pulp tissue, partial or complete pulpotomy is indicated to preserve pulpal function and allow continued root development. In many cases, injury causes loss of pulp vitality and arrested root development leading to a tooth with poor crown root ratio, a root with very thin walls, an open blunderbuss apex and development of apical pathosis.

Endodontic management of a haemophilic patient- a clinical perspective.

Haemophilia and other bleeding disorders remain an enigma to the dentists world over. They not only challenge the skills of dental specialists but also raise the question of how these individuals should be managed emotionally as well as psychologically. The high incidence of dental problems in haemophiliacs is most likely caused by the fear and apprehension not only on the part of the patients but also dentists of inducing bleeding during treatment which can even be life threatening in certain cases.
