Maxillectomy is done for a variety of disease conditions. Reconstruction following maxillectomy is done to restore the form and function. One of the important goals that are to be achieved in reconstruction is the separation of the oral and nasal cavities. In this article, we report the use of palatal flap by preserving the descending palatine artery during bilateral inferior partial maxillectomy, for separating the nasal cavity from the oral cavity. This technique eliminates the need for an obturator or another free or local flap for this purpose.

Motivation is a fundamental impulse that drives a person to behave in undertaking activities that are expected. Motivation as a concept that is used when the self emerged a desire and drive or direct behavior. The higher the intensity the higher the motivation of behavior. Maintaining a fixed gear means an action to prevent tooth decay, dental care for the sick and restoring damaged teeth and abnormalities of the hard and soft tissues to restore tooth form and function, aesthetic value and protection of the supporting tissues of the teeth and maintaining teeth as long as possible in the oral cavity. Knowledge of dental disease is important to know how to maintain healthy teeth to increase the motivation to maintain one's teeth Knowledge gained will form the attitude is a predisposition for sustaining behavior teeth.

Instrumental assessment techniques are needed to acquire quantitative information concerning the form and function of the nasal cavity. Until recently, aerodynamic methods were virtually the only source of such information. Two additional instruments are now available that purport to provide information useful to clinicians interested in assessing nasal form and function. This paper describes both the Nasometer and the acoustic rhinometer. In addition, a more traditional measure involving acoustic analysis of nasal consonants is discussed. Both the known and potential benefits and limitations of each technique are discussed.

As the tissue most directly responsible for breaking down food in the oral cavity, the form and function of enamel is obviously of evolutionary significance in humans, non-human primates and other vertebrates. Accordingly, a standard metric, relative enamel thickness (RET), has been used for many decades to provide insights into vertebrate and human palaeobiology. Relatively thick enamel has evolved many times in vertebrates including hominoids (the group to which living humans and fossil hominins belong), and this pattern is thought to provide information about taxonomy, phylogeny, functional anatomy and diet. In particular, relatively thick enamel is thought to make tooth crowns strong so that they resist fractures associated with eating mechanically resistant foods. Here, we use current models of tooth biomechanics to show that RET is at best only moderately informative of function and diet in living hominoids and fossil hominins, and at worst provides misleading information. We propose a new metric, absolute crown strength, to assess the resistance of teeth to fracture, and identify what may be a novel characteristic of tooth strength in fossil hominins.

AbstractIn rhinoplasty, the nasal dorsum represents an important aspect for form and function. Surgical management should be performed accurately to avoid complications. The goal for dorsal preservation is to preserve the keystone area intact above the nasal bones and its relationship with the upper lateral cartilages. Unlike other rhinoplasty techniques, the lowering of the nasal dorsum requires dorsal modification prior to the surgery of the tip since it modifies the tip position by rotating it. Unlike the push-down technique, that places the nasal bones inside the nasal cavity, producing obstruction of the airway, the let-down technique improves the airway and releases the valve area, making it a functional-friendly technique.

ABSTRACT Midfacial defects developed due to partial or total maxillectomy surgeries performed to remove tumors in the oral or nasal cavity. Large midfacial defects usually restored with a facial prosthesis to restore esthetics, form and function. Retention of a large facial prosthesis is a major concern to the prosthodontist because of its size and weight. This clinical report describes magnet retained intraoral-extraoral combination prosthesis for a large midfacial defect. This article also describes a technique to fabricate a hollow light-weight acrylic resin framework supporting an overlying silicone layer for the facial prosthesis.

The Relationship

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).
