External cervical resorption: an analysis using cone beam and microfocus computed tomography and scanning electron microscopy.

Aim: To provide a three-dimensional representation of external cervical resorption (ECR) with microscopy, stereo microscopy, cone beam computed tomography (CT), microfocus CT and scanning electron microscopy (SEM).

Summary: External cervical resorption is an aggressive form of root resorption, leading to a loss of dental hard tissues. This is due to clastic action, activated by a damage of the covering cementum and stimulated probably by infection.

[The first and second levels of care in endodontics].

Review of the literature shows a rather low success rate in root canal treatment. To make a correct diagnosis, to make a correct estimation of the difficulty, to work following 'standard of care' does not always simplify a root canal treatment. Referral to an endodontologist, a dentist with a specific competence and skills in endodontology, can be a solution.

Gasoline vapor exposures. Part II. Evaluation of the nephrotoxicity of the major C4/C5 hydrocarbon components.

Analysis of workplace exposures to gasoline vapors revealed that C4 and C5 hydrocarbons constitute anywhere from 67 to 74% by weight of a typical vapor. Furthermore, it was found that n-butane, isobutane, n-pentane, and isopentane together comprise greater than 90% of all the C4/C5 vapor components and approximately 61 to 67% by weight of the total vapor. Accordingly, a 21-day inhalation toxicity study of a blend consisting of 25% (w/w) each of these four hydrocarbons was conducted using rats to assess the potential for these major gasoline vapor components to induce kidney damage.

Gasoline vapor exposures. Part I. Characterization of workplace exposures.
