Five titanium plasma-sprayed implants were biopsied from a human volunteer 6 months after placement. Four test implants had been placed in immediate extraction sockets, while one implant was placed in a mature site and served as a control. The histologic analysis demonstrated that all five implants achieved osseointegration as demonstrated by light microscopy, whereas a varying degree of bone-i...

purpose: to report a case of hermansky-pudlak syndrome (hps). case report: a 7-year-old boy presented with marked generalized hypopigmentation, eye deviation and nystagmus. in addition he had history of easy bruising. visual acuity was 20/200. he had markedly translucent green irides, hypermetropic astigmatism, horizontal nystagmus and marked exotropia. funduscopy revealed a hypopigmented retin...

Twelve cases of endocardial cushion defect were studied before and after operation with ultrasono-cardiotomography (tomography) cross-sectional echocardiography, two-dimensional echocardiography, B-scan echocardiography) and M-mode scan along a horizontal section of the heart. For comparison, 20 healthy subjects, 18 cases of mitral valvular disease, 4 cases of congestive cardiomyopathy, 1 case ...

OBJECTIVE To present the authors' experience and outcomes in the reconstruction of midfacial defects using cervicofacial advancement-rotation flaps (CARFs) based on a method of determining forward or reverse design in relation to the proportions of the defect. STUDY DESIGN Case series with retrospective chart review. SETTING Tertiary care academic medical center. SUBJECTS AND METHODS Pati...

Background and aims. Furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. This study aimed to assess to compare use of ADM and connective tissue membrane in class II furcation defect regeneration. Materials and methods. 10 patient with 2 bilaterally class II furcation defects in first and/or second maxilla or man-dibular molar...

OBJECTIVE The objective of this study is to compare the putty form of bioactive glass (NovaBone Dental Putty) and particulate form (PerioGlas) in the resolution of Class II furcation defects. BACKGROUND Use of bone regeneration materials is becoming common in periodontal surgeries including furcation defects and the promising role of bioactive allograft materials has encouraged their presenta...

Aim: The aim of periodontal surgery is complete regeneration. The present study was designed to evaluate and compare clinically soft tissue changes in form of probing pocket depth, gingival shrinkage, attachment level and hard tissue changes in form of horizontal and vertical bone level using resorbable membranes. Materials and methods: Twelve subjects with bilateral class 2 furcation defects w...

In the vertebrate retina, neuronal circuitry required for visual perception is organized within specific laminae. Photoreceptors convey external visual information to bipolar and horizontal cells at triad ribbon synapses established within the outer plexiform layer (OPL), initiating retinal visual processing. However, the molecular mechanisms that organize these three classes of neuronal proces...
