BACKGROUND AND OBJECTIVES Few standardized testing procedures exist for instruments intended for Natural Orifice Translumenal Endoscopic Surgery. These testing procedures are critical for evaluating surgical skills and surgical instruments to ensure sufficient quality. This need is widely recognized by endoscopic surgeons as a major hurdle for the advancement of Natural Orifice Translumenal En...

ABSTRACT The purpose of this study was to analyze the overjet and overbite behavior during eruption of the upper permanent incisors. Fourth-eight plaster casts of 16 patients from ages 6-13 years were appraised longitudinally. It was found that the overjet remains constant, starting at the eruption of the upper permanent central incisors until eruption of the upper permanent canine teeth, while...

Eruption disturbances related to the position include ectopic eruption and transpositions. The occurrence of ectopic eruption is most commonly associated with maxillary incisors. The normal eruption, position and morphology of these teeth are crucial to craniofacial development, facial esthetics as well as phonetics. It is essential that the clinicians have thorough knowledge of the eruption di...

Tooth eruption is a localized process in the jaws which exhibits precise timing and bilateral symmetry. It involves resorption and formation of bone on opposite sides of the erupting tooth and these activities depend on the dental follicle, a thin connective tissue investment of the developing and erupting tooth. Biochemical studies have shown that during eruption cells, proteins and enzymes ch...

AbstractSurgical treatment of coxo-femoral dysplasia (CFD) is quite difficult. The use al aiming reduction forceps in the installation toogling rode an alternative method that can be further developed for handling CFD without osteotomy femoral head (FHO). combination among good action, appropriate and rehabilitation therapy could ideal step better recovery patients with CFD. Complete this case ...

Ectopic eruption into the dental environment is common, whereas eruption into other sites is rare. Diverse anatomical locations such as the mandibular condyle, coronoid process, palate, maxillary sinuses and nasal cavity can infrequently be the site of ectopic tooth eruption. One of the nondental sites for ectopic eruption is the maxillary sinus. Here, we present a case of dentigerous cyst with...

Objective: To determine the chronological eruption parameters of primary teeth in Indian children. Study Design: A longitudinal study consisting of 135 healthy children (74 boys and 61 girls) attending three child health centres in the city of Hyderabad, India were randomly selected and followed from the emergence of the first to the last tooth. Ages and order of tooth eruption were studied for...

Multi-model simulations show a post-Pinatubo eruption sequence of Pacific sea surface temperatures (SSTs) that includes a La Niña-like pattern the third northern winter after an eruption, opposite in sign to what was observed after Pinatubo. This leads to the loss of hindcast skill for years in the 1990s affected by the Pinatubo eruption because the post-eruption internal variability of the cli...

Damavand volcano is located 60 km to the East North- East of Tehran. It is a dormant stratovolcano outcrop in the Alborz Mountains of northern Iran and is the highest mountain (5670 m) in the Middle East and West Asia. Mazandaran Province, one of the most populous provinces by population density, Semnan and Gorgan provinces further east are neighbours of the Damavand. Volcanism in Damavand goes...

IN about one-fifth of all cataracts that come to this hospital for extraction the lens capsule is slippery, so that when one tries to grip it with forceps by the conventional methods, the forceps slip and it is not possible to apply any traction. About 75 per cent. of these cases are Morgagnian cataracts and the rest are intumescent cortical senile cataracts. The technique described below makes...
