“The aim of this JNK-IN-8 in vitro study was to evaluate the morphological changes that occur in tooth enamel after mechanical instrumentation and after femtosecond laser irradiation with different parameters via light and scanning electron microscopy (SEM). Twelve totally impacted third molars were collected and sectioned to provide several cut surfaces. These surfaces were exposed to infrared (lambda = 795 nm, 120 fs, 1-kHz repetition rate, maximum mean power 1 W) laser pulses and machined by means of a conventional mechanical technique. Two very different geometrical

patterns were performed with femtosecond laser pulses: shallow rectangular cavities and deep cylindrical ones. The results of both machining procedures were examined using light and scanning electron microscopy. The SEM images show the femtosecond laser ability to produce high-precision cavities in tooth enamel. No signs of collateral damage, burning, melting, or

cracks were observed despite the far different laser pulse energies used (ranging from 7 to 400 mu J), unlike what is seen with conventional mechanical techniques. The femtosecond laser has the potential 3-MA to become an optimal tool for the treatment of dental decay and as an alternative to the conventional drill to reduce mechanical damage during removal of the hard dental tissue.”
“Objective: To describe and characterize diplopia resulting from skew deviation after cerebellopontine angle (CPA) surgery and labyrinthectomy.

Patients and Interventions:

Retrospective case series of 4 patients who developed vertical diplopia from skew deviation after resection of tumors in the CPA or labyrinthectomy

Main Outcome Measure: Complete neuro-opthalmologic examination EPZ-6438 clinical trial including opticokinetic testing, confrontational visual field assessment, color plate, pupillary reflex, slit lamp examination, and head tilt test.

Results: Four patients with residual hearing preoperatively developed skew deviation immediately after surgical intervention, including translabyrinthine (n = 1) and retrosigmoid (n = 2) approaches to the CPA and labyrinthectomy (n = 1). Neuroophthalmologic examination demonstrated intact extraocular movements, and 2- to 14-mm prism diopter hypertropia on both primary gaze and head tilt testing. In all cases, skew deviation resolved spontaneously with normalization of the neuro-ophthalmologic examination within 10 weeks.

Conclusion: Patients undergoing CPA surgery or labyrinthectomy can develop postoperative diplopia due to skew deviation as a consequence of acute vestibular deafferentation. Patients with significant hearing preoperatively, a probable marker for residual vestibular function, may be especially at risk for developing skew deviation postoperatively.
