INTRODUCTION Maxillary surgery on a bone segment enables movement in the sagittal and vertical planes. When performed on multiple segments, it further provides movement in the transverse plane. Typical sites for interdental osteotomies are between laterals and canines, premolars and canines, or between incisors. Additionally, osteotomies can be bilateral, unilateral or asymmetric. The ability t...

AIM To analyze the influence of various placement techniques on Vickers microhardness of Class II cavities restored using resin composite in different depths and layers. METHODS AND MATERIALS Sixty-four standardized Class II cavities (5.0 x 3.0 x 1.5 mm3) were prepared in sound human, maxillary premolars. The cavities were divided into four experimental groups (n=16) according to the composit...

background and aims. maintenance of interdental soft tissue and the need for aesthetics are increasingly recognized as important criteria for implant success. the aim of this prospective clinical study was to compare the peri-implant and prosthetic conditions for single-tooth implants, placed according to the immediate (im) and the delayed (de) placement protocols at 18-month follow-up examinat...

factor  is introduced for direct head loss calculation and sizing in dual-diameter laterals of sprinkler and trickle irrigation systems when the hazen-williams equation is to be applied. application of this factor prevents trial and error and uses fewer head-loss equations in calculating the total friction loss and designing dual-diameter laterals. the proposed factor is a function of total num...

This study investigates phonetic factors – vocalic/consonantal context, duration, stress favouring rhotic perception of the lateral approximant in Greek. Nonsense words containing the lateral in different lengths in both intervocalic and internal coda position, alongside similar words containing a rhotic, were presented to Greek listeners for categorisation as /l/ or /r/. Results showed that la...

The purpose of this study was to determine the prevalence of peg laterals and small lateral incisors in orthodontic patients, visiting the orthodontic department, faculty of dentistry, the university of Lahore. The data (history sheets, dental casts and panoramic radiographs) of 230 patients (36.5% males, 63.5% females; mean age: 16.4 years) were randomly selected from orthodontic patient’s rec...

the effects of environmental factors on germination and emergence of hoary cress seeds were examined in laboratory and field experiments. germinability of hoary cress under light/dark conditions (90%) was significantly higher than when seeds were incubated under continuous dark (78%). hoary cress could germinate in a broad range of temperatures (15/6, 20/10, 25/15, 30/15, and 35/20?c). the germ...

Velar lateral sounds are rare and their acoustics contextual effects understudied. Positional variants of velar laterals also rarely reported. This paper documents a previously unknown allophony pattern the in Mee (Trans New Guinea; Indonesia), based on an elicitation study with two speakers controlled set recordings from one speakers. Our main dataset included carrier phrase words lateral, rep...

Root perforations are significant complications of endodontic treatment. However, when teeth are of strategic value, perforation repair is clearly indicated. The successful utilization and placement of a subgingival resin-ionomer restoration to repair an endodontic root perforation is demonstrated. Sustained tissue health and minimal probing depths at the surgical site demonstrate clinical succ...
