This study was performed to evaluate the effect of using attachment on implant supported distal extension lower partial overdenture. Ten lower kennedy class II partially edentulous patients were selected to receive implant at second molar area, then patients were divided into 2 groups according to the implant superstructures either (dome shaped-or-ball and cap attachment). Patients of both grou...

It is difficult to predict where the effective measurement plane is situated with dome-shaped diffusers often used in commercial photometers and radiometers. Insufficient knowledge of this plane could lead to large systematic errors in calibration of the illuminance responsivity of photometers. We propose a method that can be used to determine this reference plane accurately, based on the inver...

This study was performed to compare between two types of implant supported overdentures, with and without attachments. Methods: Fourteen completely edentulous patients received two implants in the canine region and loaded 3 months thereafter. Patients have been grouped into two groups; group Iconsisted of seven patients with two ball attachments and group II seven patients with support only (do...

We describe the case of a nine-day-old female Holstein calf which had cheiloschisis, a moderate dome-shaped head, ataxia and opisthotonus since birth. No significant findings except the dome-shaped head were observed on survey radiography of the skull. Computed tomography (CT) images showed bilateral lateral ventriculomegaly, cerebellar hypoplasia and a cyst-like lesion communicating with the r...

Numerical studies of the vector electromagnetic fields in plano-concave microresonators have recently revealed that a photonic analogue of spin-orbit coupling can occur in paraxial geometries. Laguerre-Gauss modes with circular polarization are then no longer the correct eigenstates, even if the resonator is axially symmetric. A crucial role in this effect is played by the presence of a boundar...

Previously published Photo Quizzes are now featured in a mobile app. Get more information at http:// www.aafp.org/afp/apps. A 42-year-old man with a history of basal cell carcinoma on his scalp (five years earlier) presented for an annual examination. He reported inconsistent sunscreen use and did not have any new or concerning lesions. He did have a papule on his upper lip that had not changed...

DOI: 10.4103/ijd.IJD_746_16 A 45-year-old male presented with a single, asymptomatic swelling over the left cheek of 10-year duration. Cutaneous examination revealed solitary 7 mm × 7 mm skin colored to slightly hyperpigmented nontender nodule over the left malar area adjacent to the nose [Figure 1]. It was soft in consistency with limited mobility. The overlying skin was apparently normal with...
