Maxillary second premolar with three roots and three separate root canals--case reports.

Aberrations in root canal systems are a commonly occurring phenomenon. Knowledge of the basic root canal anatomy and its variation is necessary for successful completion of endodontics. Maxillary second premolars usually have one root and one canal. The occurrence of these teeth having three roots and three canals is very rare. Three such cases of maxillary second premolar with three roots and three canals are presented here.

Assessment of the efficacy of an indigeniously developed pulse oximeter dental sensor holder for pulp vitality testing.

Current routine methods of assessment of pulp vitality rely on stimulation of nerve fibres and give no direct indication of blood flow within the pulp. Pulse oximeter is a proven, atraumatic method of measuring vascular status, by evaluating oxygen saturation. This study explores the use of customized dental pulse oximeter sensor holder to assess pulpal vascular oxygen saturation in permanent teeth. Pulse oximeter readily differentiated between known vital and nonvital teeth. Vital teeth consistently provided oxygen saturation values that were lower than the values recorded on the patient's fingers. Pulse oximeter is an accurate, atraumatic clinical alternative to the present electrical and thermal methods of assessing pulp vitality in teeth.

Endodontic management of taurodontic teeth.

Taurodontism is a morpho-anatomical change in the shape of the tooth in which the body of the tooth is enlarged and the roots are reduced in size. Although taurodontism is a dental rarity, this unusual radicular form should merit circumspect considerations in planning and treatment. Endodontic management in taurodont teeth has been described as complex and difficult. The present paper describes the successful completion of endodontic treatment in three taurodontic teeth with appropriate use of instruments and techniques and also emphasizes the need for post endodontic rehabilitation.

Criteria for management of calcific metamorphosis: review with a case report.

Calcific metamorphosis is seen commonly in the dental pulp after traumatic tooth injuries and is characterized by deposition of hard tissue within the root canal space. Opinion differs among practitioners as to whether to treat these cases upon early detection of calcific metamorphosis or to observe them until symptoms or radiographic signs of pulpal necrosis are detected. In this article, the clinical, radiographic, and histopathologic appearance of calcific metamorphosis is described; a review of the literature is presented to address these issues in an attempt to establish sound rationale for treatment. Approximately 3.8% to 24% of traumatized teeth develop varying degrees of calcific metamorphosis. Studies indicate that of these, approximately 1% to 16% will develop pulpal necrosis. Most of the literature does not support endodontic intervention unless periradicular pathoses is detected or the involved tooth becomes syptomatic. It may be advisable to manage cases demonstrating calcific metamorphosis through observation and periodic examination. A report of a case where in non-surgical endodontic intervention was successfully carried out a patient suffering from calcific metamorphosis with periapical pathoses is also presented.

Bilateral mandibular canines with type two canals.

Presence of two canals with type II pattern in mandibular canine is around 15%. Even though the incidence rate is high, multiple angled diagnostic radiographs are not regularly taken. This article highlights the importance of multiple angled radiographs and indicates that the dentist should have a mind set to look out for extra canals in all root canal cases.

Carpal tunnel syndrome: survey of an occupational hazard.

Carpal tunnel syndrome (CTS) is one of a number of muscle-tendon and nerve related disorders that affect people performing intensive work with their hands. Hand and wrist disorders are receiving most of the attention although their symptoms are reported less often by dental workers than symptoms of neck/back disorders. The lack of data pertaining to the behaviour of Indian general dental practitioners towards carpal tunnel syndrome was the basis behind this descriptive study to evaluate the prevalence of carpal tunnel syndrome symptoms.
