Abstract Background: The percentage of satellite cells rapidly decreases in aneurally regenerating soleus muscles rat. Also denervation intact causes fiber loss and regeneration, but the fate is unknown; myonuclei have been suggested to undergo changes resembling those apoptotic cells. Methods: Rat extensor digitorum longus (EDL) were denervated at birth or age 5 weeks investigated after periods up 38 weeks. At least 400 each muscle assessed by electron microscopy, cell nuclei counted. In...

Histomorphometrical assessment of regenerated peripheral nerves is a very common goal many studies in experimental microsurgery. In this paper, the main critical issues nerve fiber sampling for quantitative morphological are addressed. The equal opportunity rule, i.e., basic paradigm random sampling, described, together with an explanation how errors, selection histologic fields and fibers inside them, can produce bias estimates. Finally, some practical suggestions on to cope most errors...

Abstract Although veins and arteries present similar wall structures, there are differences which may be relevant in peripheral nerve reconstruction. Inside‐out vein grafts (IOVG) have been satisfactorily used to repair both motor sensitive nerves. However, the inside‐out artery graft (IOAG) is a new technique not fully investigated. Our study presents comparative morphological data on regeneration achieved with IOVG IOAG of Wistar rat sciatic Jugular aorta were harvested from donor animals...

BACKGROUND: Effective pain control in Dentistry may be achieved by local anesthetic techniques. The success of the technique mandibular structures depends on proximity needle tip to foramen at moment injection into pterygomandibular region. Two techniques are available reach inferior alveolar nerve where it enters canal, namely indirect and direct; these differ number movements required. Data demonstrate that is considered ineffective 15% cases direct 13-29% cases. OBJECTIVE: aim this study...

Aim: The aim of this study was to describe the histological characteristics altered human lingual frenulum. Materials and Methods: Between March July, 2011, 50 children between 6 months 4 years age were assessed by a Speech Language Pathologist in Public Health Care Service Brotas – Sao Paulo, Brazil. frenulum evaluation protocol proposed Marchesan (2010, 2012) administered 26 male 24 female. Of 50, 8 had alterations. with alteration underwent frenectomy. materials for analyses taken from...

Objective: Evaluate the efficacy of low-level laser therapy (LLLT) on qualitative, quantitative, and functional aspects in facial nerve regeneration process. Materials methods: Forty-two male Wistar rats were used, randomly divided into a control group (CG; n = 10), which without lesion was collected, four experimental groups: (1) suture (SEG) (2) fibrin (FEG), consisting 16 animals buccal branch sectioned both sides face; an end-to-end epineural performed right side, sealant used left side...

The purpose of this study was to evaluate the effects low-intensity pulsed ultrasound at 1.0 MHz on healing process fractures with bone loss in rat fibula by alkaline phosphate level measurement and radiologic analyses.Thirty 70-day-old male Wistar rats underwent a resection 2.5 3.0 mm between proximal middle third right fibular diaphysis. animals were randomly divided into 3 experimental groups: reference (uninjured), control (injured only), treated 5 applications ultrasound, interspersed 2...

Nerve regeneration in a sensory nerve was obtained by the application of different techniques: inside-out vein graft (IOVG group) and standard (SVG group). These techniques provide good microenvironment for axon motor nerves, but their efficiency nerves is controversial. The saphenous nervtce sectioned repaired rats. After 4, 12, 20 weeks distal stump were observed under electron microscopy. In each studied period, pattern, diameters, thickness myelin sheaths regenerated axons measured...

It is known that a vein graft provides good microenvironment for axon regeneration in motor peripheral nerves, but the use of artery sensory nerves controversial. We sectioned saphenous nerve and repaired it by using heterologous inside-out standard techniques rats. After 4, 12, 20 weeks, distal stump were observed under electron microscopy. In each period studied, pattern, diameters, thickness myelin sheaths regenerated axons measured stump. There was capillary invasion both stump,...

Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia presence of teeth areas distant from alveolar process. Initial angulation bud second premolar and premature loss permanent mandibular 1st molars can influence distal migration premolar. Some studies have observed that ectopic be found a variety places around oral cavity also other human body. There records maxillary sinus, condyle, coronoid process, angle, orbit, palate,...

The purpose of the Dental Sculpture and Anatomy discipline is to introduce undergraduate students study anatomic morphological characteristics permanent primary human dentition, through classes, books cognitive psychomotor activities.This supports teaching specific knowledge necessary for a more extensive education, involving interdisciplinarity as means exchange among several areas dentistry, achieve comprehensive professional education.Students must recognize dental morphology from samples...

Abstract There are several differences between red and white muscles submitted to different experimental conditions, especially following denervation: a) denervation atrophy is more pronounced in than muscles; b) the size of fibers does not vary parts muscle before after denervation, when compared c) regional difference initially muscle; d) deep present degenerative changes such as disordered myofibrils sarcolemmal folds long‐term denervation; e) myotube‐like with central nuclei occur...

Facial palsy, parotid diseases and others are a relatively common clinical condition with variety of causes.Irrespective its etiology, facial palsy always represents very serious problem for the patient.Parotid gland also occurrence.In this particular case, knowledge surgical anatomy nerve correlations is important an adequate preservation in cases surgery benign malignant gland.Although has been well documented, concept treatment tumors, (neurorraphy techniques) submandibular approach...

Styloid syndrome is characterized by an elongated styloid process or calcification of the stylomandibular and stylohyoid ligament.This study describes a case 65-year-old woman who presented to Stomatology Clinic, University Marilia with temporomandibular joint pain, ear ringing reduced ability open mouth.Panoramic posteroanterior digital radiographs showed bilateral elongation processes, especially right side, whose length extended beyond mandible angle.The diagnosis was confirmed...

To compare the functional result of standart vein grafts and inside-out graft technique on sciatic nerve repair.We used 24 male Wistar rats divided into 4 groups: control group (CG), standard (SVG), Inside-out (IOVG) denervated Group (DG). SVG, IOVG DG underwent total section nerve, SVG however repair surgery using a with normal jugular vein, respectively. Histological analysis soleus Extensor Digitorum Longus (EDL), Sciatic Functional Index were to results after 6 weeks.Both acted favorably...
