Many an attractive smile are marred by discolouration or staining, either of an individual tooth or of all teeth, which has a far-reaching psychological impact. Management of intrinsic stains have in the past relied on masking discolourations by full-coverage crowns. Today, the Minimal invasive concepts, methods and techniques have permeated in all disciplines of dentistry and esthetic dentistry is no exception. The minimally invasive approach in dentistry is based on safeguarding and shielding the tooth structure framework, especially enamel. Biomodification is the rationale or a process by chemical, physical, genetic means oftransmogrifying aliving organism. In dentistry, biomodification is a non-invasive or a minimally invasive concept which by chemical or physical means bring about a revision in tooth architecture. This paper gives an insight to the current status and emerging minimal invasive and non-invasive trends like microabrasion, macroabrasion and bleaching or a combination of these in management of discoloured dentition.

“…In this uncertain diagnosis [7], the practitioner may opt either to treat the lesion or only to monitor it, with questionable benefits in time [8]. In this specific lesional stage, air abrasion is the method of election, as bur preparation of pits and grooves would remove a greater quantity of healthy dental tissues as compared to air abrasion, which is more conservative [9].…”

Dental air abrasion is a minimally invasive, ultraconservative method, with indication of choice for incipient fissural caries, which still count for % of newly appeared caries and raise diagnosing problems of the lesional stage. In this context, the aim of the paper was to use and assess dental air abrasion as an alternative technique for the preparation of dental structures, both on extracted teeth and on patients. "io-"rt microblaster was used on extracted teeth and patients for the removal of fissural caries in molars and premolars. "fter being acquainted with the technique and according to the specific protocol of use, minimally invasive preparations were made, followed by their restoration with adhesive materials. The advantages of the method, also specified by similar surveys, were absence of pain, vibration, noise, pressure, and heat that are generated by conventional methods burs , leading to high acceptance by patients.

“…Gas-solid two-phase flows have been studied extensively, particularly with respect to pneumatic conveying (Wypych 2008;Saether et al 2009;Klinzing et al 2010) erosion in pipes, power turbines, and impeller fans (Grant and Tabakoff 1975;Parslow et al 1999;Graham et al 2010), and material removal processes including microabrasive air jet machining, sandblast finishing and air-abrasion dentistry (Wang and Li 2003;Li et al 2009;Hegde and Khatavkar 2010). However, solids suspended in flows moving through rotating power machinery are typically viewed as detrimental.…”

Pneumatic energy is converted into solid particle kinetic energy as a solid-particle-entrained gas flows downward through a vertical nozzle. For the conditions studied, the solid particles serve as a heat exchange medium to enable a gas expansion that is nearly isothermal. Also, the kinetic energy associated with the two-phase fluid is predominantly that associated with subsonic solidparticle motion. The kinetic energy of the solid particles is converted into other forms using a low-speed turbine. A theoretical description of the process is presented, and the initiation of an experimental effort to study the process is described. Experimental gas phase temperature measurements indicate the realization of isothermal expansion. Experimental turbine erosion rate measurements indicate that relatively low erosion rates occur for the conditions studied.
