Multiple idiopathic cervical root resorption: systematic review and report of four cases.

Objectives: The objectives of this study were to report four cases of multiple idiopathic cervical root resorption and to systematically review the literature on this condition.

Methods: The clinical and radiographic findings and the medical/dental histories of four patients who presented with multiple idiopathic cervical root resorption were recorded. Additionally, 10 references from the literature that reported on 14 patients were reviewed.

Radiographic manifestation of clear cell odontogenic tumor.

Clear cell odontogenic tumors are uncommon, only 20 cases having been reported in the literature. We report a case that presented with unique radiographic manifestations over a period of 12 years; no similar case has been reported to date. Documentation of the malignant nature of the condition and of the range of clinical and radiographic manifestations with which this neoplasm can present provides useful insight into its pathogenesis and progression.

Gingival telangiectases: an underappreciated physical sign of juvenile dermatomyositis.

Background: MEDLINE searches (1966-June 1969) failed to identify references that give detailed descriptions of the oral manifestations of dermatomyositis (DM). However, several reports predating MEDLINE provided more complete descriptions of oral lesions associated with DM.

Observations: We describe 5 cases of juvenile DM with oral manifestations, primarily in the form of gingival telangiectases.

Laser Doppler flowmetry: a clinical test of pulpal vitality.

Problem: A rapid, accurate, noninvasive method of determining pulpal blood flow would be helpful in determining pulpal vitality.

Objective: The purpose of this study was to determine if laser Doppler flowmetry can measure induced changes in pulpal blood flow.

Study Design: Two percent lidocaine with epinephrine 1:100,000 was infiltrated into the labial vestibule to anesthetize five anterior teeth in healthy human volunteers.

Comparison of two laser Doppler systems on the measurement of blood flow of premolar teeth under different pulpal conditions.

An in vivo investigation was conducted to assess the ability of two laser Doppler flowmeters (DRT4, Moor Instruments Ltd; Laserflo BPM2, Vasamedics) to differentiate between vital pulp, ischaemically necrosed pulp, and an empty pulp chamber in premolar teeth in children. Sixteen intact, vital teeth in need of extraction for orthodontic purposes were identified. Laser Doppler blood flow readings were taken prior to (T1) and after the administration of adrenaline-free local anaesthetic (T2), after extraction and replantation of the teeth (T3), and after broaching the pulp tissue and replanting the teeth (T4).
