      The greatest majority of the patients have a huge fear of the shot given by the dentist before an extraction, or before a dental filling is performed. No more fears from now on, because good news is on the way. The DentalVibe is an innovative dentistry instrument patented in the US, which is meant to alleviate the pain felt from intra-oral injections. Sometimes, the dentist needs to make even tw o or three such shots to numb a greater area within the mouth, and now thanks to this advanced technology, the fear of injections should be gone forever. This is a rechargeable and cordless instrument, which actually delivers some micro-oscillations, or vibrations as commonly known, right to the site where the shot needs to be administered. The instrument is designed based on the Vibra Pulse technology, which basically helps blocking the neural pain gate while the shot is administered, thus eliminating completely the feeling of pain. Instead of the dre...

A ranula is a type of mucocele found on the floor of the mouth . Ranulas present as a swelling of connective tissue consisting of collected mucin from a ruptured salivary gland duct , which is usually caused by local trauma. The Latin rana means frog , and a ranula is so named because its appearance is sometimes compared to a frog's underbelly.  ETIOLOGY : Ranulas Congenital ranulas can arise secondary to an imperforate salivary duct or ostial adhesion. These are very rare and have been known to spontaneously resolve. Posttraumatic ranulas arise from trauma to the sublingual gland, leading to mucus extravasation and formation of a pseudocyst. The more appropriate term for this may be mucus escape reaction (MER). Pathophysiology Ranulas are formed from 1 of 2 processes: Partial obstruction of a sublingual duct can lead to formation of an epithelial-lined retention cyst. This is unusual, occurring in less than 10% of all ranulas. Trauma can lead to fo...

A Chennai dental hospital has been chosen as one of the nine sites for an international clinical trial on zygoma tooth implants. Zygoma teeth are the new-age permanent implants used instead of dentures by people who have lost their teeth because of various diseases or genetic disorders. Zygoma prosthetics shorten the time taken for a tooth implant procedure from one year to 72 hours. “Many young people lose their teeth to aggressive peritonitis, or gum disease. We do not know what causes the disease, but the sufferer’s teeth become loose and fall off and even his jaw bone is destroyed,” explains Dr R. Gunaseelan, oral and maxillofacial surgeon at Rajan Dental Institute, which will be Asia’s second trial centre after a hospital in Hong Kong. “Surprisingly, 90 per cent of my patients who lose all their teeth are below 40 years of age. It is inconvenient and a social embarrassment for young people, especially those of marriageable age, to wear a set of dentures,” he adds Z...

                          Dr Tomisaku Kawasaki published a case series of 50 children in 1967, who were febrile and all had a rash, non-exudative conjunctivitis, erythema of the palms and soles of the feet, and cervical lymphadenopathy. This constellation of signs Dr Kawasaki termed “acute febrile mucocutaneous syndrome”; however the eponym Kawasaki disease has been accepted worldwide.  Symptoms Kawasaki disease often begins with a high and persistent fever greater than 102 °F, often as high as 104 °F. A persistent fever lasting at least 5 days is considered a classic sign. The fever may last for up to 2 weeks and does not usually go away with normal doses of acetaminophen (Tylenol) or ibuprofen . Other symptoms often include: Extremely bloodshot or red eyes (without pus or drainage) B...

A club foot , or congenital talipes equinovarus ( CTEV ), is a congenital deformity involving one foot or both. The affected foot appears rotated internally at the ankle. TEV is classified into 2 groups: Postural TEV or Structural TEV.  . Etiology The true etiology of congenital clubfoot is unknown. Most infants who have clubfoot have no identifiable genetic, syndromal, or extrinsic cause. Extrinsic associations include teratogenic agents (eg, sodium aminopterin), oligohydramnios , and congenital constriction rings. Genetic associations include mendelian inheritance (eg, diastrophic dwarfism; autosomal recessive pattern of clubfoot inheritance). Cytogenetic abnormalities (eg, congenital talipes equinovarus [CTEV]) can be seen in syndromes involving chromosomal deletion. It has been proposed that idiopathic CTEV in otherwise healthy infants is the result of a multifactorial system of inheritance. Evidence for this is as follows: Incidence in the general populati...

Langerhans cell Histiocytosis ( LCH ) is a rare disease involving clonal proliferation of Langerhans cells , abnormal cells deriving from bone marrow and capable of migrating from skin to lymph nodes . Clinically, its manifestations range from isolated bone lesions to multisystem disease . LCH is part of a group of clinical syndromes called histiocytoses , which are characterized by an abnormal proliferation of histiocytes (an archaic term for activated dendritic cells and macrophages ). These diseases are related to other forms of abnormal proliferation of white blood cells , such as leukemias and lymphomas . The disease has gone by several names, including Hand-Schüller-Christian disease , Abt-Letterer-Siwe disease , and histiocytosis X , until it was renamed in 1985 by the Histiocyte Society. Causes, incidence, and risk factors Histiocytosis X has typically been thought of as a cancer-like condition. More recently researchers have begun to suspect that it is actua...
