Geographic tongue
Other names:
Erythema Migrans, Benign Migratory Glossitis, Erythema Areata Migrans, Stomatitis Areata Migrans
Wandering Rash, Glossitis Areata Exfoliativa , Lingua Geographica, Transitory Benign Plaques Of The Tongue , Dorsal surface of the tongue
It is categorized as a chronic inflammatory condition of the tongue characterized by small patches disappear and reappear in a short period of time (hours or days), change in shape or size. the lesions appear as annular, circinate, or serpiginous along with slightly depressed atrophic centers (devoid of filiform papillae) and raised grayish white borders. Co-existence of fissures may also be present. Burning sensation occurs when tongue comes in contact with tomato, cheese, mouth rinses etc. Whitish/yellow discoloration of the tongue is frequently due to a yeast infection
Main etiological factors responsible are : environmental sensitivity-asthma, allergies, stress, smoking , harmonal changes-pre-mensturation, pregnancy, vitamin deficiency
Histopathology:
Irregular areas of dekeratinized and desquamated filiform papillae (red in color) are surrounded by elevated whitish or yellow margins due to acantholysis and hyperkeratosis. Neutrophils migrate into the epithelial layer, creating what are termed Munoros abscesses.
It is linked with psoriasis on the basis of presence of these abscesses. However, both the entities are different.
Treatment:  
Remove known etiology
Smear for detection of candida; apply candid solution
Steroid application-Triamcinolone Acetonide Dental Paste USP,0.1%
Vit B supplements
Zincum Gluconium 2x, 13.3 mg-Cold-Eeze -Relieves in 2 days (homeopathic)
Chewing mint leaves/ candies

Nanotechnology: Need of the hour


       Nanotechnology is the science and technology of diagnosing, treating and preventing disease and traumatic injury; of relieving pain; and of preserving and improving human health, through the use of nanoscale-structured materials, biotechnology and genetic engineering, and eventually complex molecular machine systems and nanorobots.
         Prospective of a nanotech world:
   Ø It helps in the detection of tumor location, size, shape at a molecular level
   Ø Delivery of anticancer drugs to specific site
   Ø Target specific imaging
   Ø Overcome both non cellular and cellular-based drug resistance, to increase selectivity of drugs.
   Ø Remove microvascular obstruction
   Ø Perform non invasive tissue transplants
   Ø  Molecular repairs
   Ø Exchange new whole chromosomes
     (Further reference: Annals & Essences of dentistry.Vol IV Issue 1 Jan-Mar 2012)
        Goodbye to dental drills: Nanoneedles and Nanotweezers
   Ø Restoration of tooth structure with fluoride,calcium,phosphate releasing nanocomposites.
   Ø Dental enamel formation using nanorods, nanospheres, and recombinant amelogenins.
   Ø Delivery of Local anesthesia
   Ø  Dentition renaturalization
   Ø  Permanent hypersensitivity cure
   Ø  Complete orthodontic realignments during a single office visit
   Ø  Continuous oral health maintenance using mechanical dentif-robots incorporated in mouthwash & toothpaste.
