background :soft tissue profile can be widely different in various populations. furthermore, this profile can be also continues to change throughout life. however, there are few studies that quantitatively evaluate the soft tissue profile in iranian population. in order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissue ...

introduction: fishbone is the most common foreign body found in the oropharynx. conventionally patients with suspected fishbone in the throat would have mirror laryngoscopy followed by lateral soft tissue x-ray to look for the fishbone or observe impacts caused by the fishbone i.e. soft tissue swelling or air in upper esophagus. however, the most common site of fishbone impact is the suprahyoid...

background: abdominal circumference (ac), biparietal diameters (bpd) and femoral length (fl) are now the main parameters used to obtain estimated fetal weight (efw). although the role of soft tissue parameters in determining fetal weight was proved but clinical attention to mid-thigh soft tissue thickness (stt) is limited. objective: to find the impression of stt on birth weight (bw) and repres...

background: laser-tissue interaction on low-level laser therapy (lllt) has widespread medical applications (e.g., improved wound healing). the tensile strength of radiated tissue by lllt is known to be increased mainly because of cross collagen bands developed after radiation. objective: in this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic t...

introduction: the purpose of this preliminary study was to evaluate the periodontal condition of intruded molars in various phases of treatments. methods: 30 patients with at least one overerupted upper first molar were selected. upper molar bands with brackets were cemented. two miniscrews were placed in the mesiopalatal and mesiobuccal aspect of the aforementioned teeth. a titanium molybdenum...

We present a Parylene neural microprobe array and the first demonstration of deep brain (> 5 mm) implantation of bare polymer probes, enabled by a novel micropackaging technique. Targeting brain sites below the surface of the cortex with soft polymer probes typically requires bulky overcoats or insertion shuttles, which greatly increase probe dimensions and tissue damage, negating advantages of...

the purpose of these case reports is to analyze the results of gingivectomy and gingival troughing to determine the evidence on the effectiveness of laser-assisted soft tissue procedures and soft tissue management in aesthetic dentistry.the patients in these case reports underwent 980 nm diode laser assisted gingivectomy and gingival troughing to achieve immediate hemostasis and moisture contro...

BACKGROUND Robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations. OBJECTIVE In this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diagram. Non-homogenous camel liver can be exploit...
