REVIEW
Nanotechnology in dentistry
Saravana R Kumar, R Vijayalakshmi
April-June 2006, 17(2):62-5
DOI:10.4103/0970-9290.29890  PMID:17051869
Nanotechnology is manipulating matter at nanometer level and the application of the same to medicine is called nanomedicine. Nanotechnology holds promise for advanced diagnostics, targeted drug delivery, and biosensors. In the long-term, medical nanorobots will allow instant pathogen diagnosis and extermination, individual cell surgery in vivo, and improvement of natural physiological function. Current research is focusing on fabrication of nanostructures, nanoactuators, and nanomotors, along with means to assemble them into larger systems, economically and in great numbers.

Clinical evaluation of an ionic tooth brush on oral hygiene status, gingival status, and microbial parameter
J Deshmukh, KL Vandana, KT Chandrashekar, B Savitha
April-June 2006, 17(2):74-7
DOI:10.4103/0970-9290.29887  PMID:17051872
It has long been recognised that the presence of dental plaque leads to gingivitis and periodontal disease, as well as dental caries. Today tooth brushing is the most widely accepted method of removing plaque. Hence this present clinical study was undertaken to evaluate the effectiveness of an ionic toothbrush on oral hygiene status. For this study, 20 dental students in the age group of 18-20 years were included. All the subjects after undergoing dental prophylaxis were then provided with ionic toothbrushes, either active (equipped with lithium battery) or inactive (without lithium battery). Plaque index and gingival bleeding index were examined at 7th, 14th, and 21st day. Microbial assessment was done for detection of colony forming units (CFU) from the plaque samples which were collected on 0 day and 21st day, both before brushing and after brushing. Results shown a significant reduction in all the parameters and the reduction was more significant in active and inactive ionic toothbrush users. It was concluded that both active and inactive ionic toothbrushes reduced the plaque index and gingival bleeding index scores significantly and active ionic tooth brushes were more effective as compared to inactive ionic toothbrushes. There was no soft tissue trauma following the use of both type of toothbrushes, which showed that ionic toothbrushes were equally safe for regular long-term use.

CASE REPORT
Tuberculous ulcer of tongue with oral complications of oral antituberculosis therapy
GN Ajay, C Laxmikanth, SK Prashanth
April-June 2006, 17(2):87-90
DOI:10.4103/0970-9290.29884  PMID:17051875
Tuberculosis (TB) is an infectious disease affecting humans of all ages in all parts of the world. The dentist plays an important role in the identification and control of this condition by early recognition of oral lesions that may precede the detection of the pulmonary form. Occurrence of increased incidence of mycobacterial infections as a part of the spectrum of AIDS only emphasizes the importance of early diagnosis. A case of a tuberculous ulcer on the tongue along with oral ulcerations, which occurred as a consequence of oral antituberculosis therapy (ATT), is presented. Such complications have rarely been reported in the literature and the management of these is described herein. The tuberculous ulcer healed uneventfully in five weeks after institution of ATT and the other ATT-induced ulcers healed after a week of topical anesthetic application. The clinical presentations, differential diagnoses to be considered, and management of such oral manifestations is discussed. The occupational risk posed by TB to the dentist and appropriate precautions to be observed have been highlighted.

Desquamative gingival lesions are non-plaque induced inflammatory gingival lesions. It is a clinical description and not a diagnosis. These desquamative lesions represent oral manifestations of various dermatoses. Systemic lupus erythematous (SLE), one of the rare dermatoses shows desquamative lesions as the oral manifestation. We here with report a case of SLE with oral lesions involving gingiva of a 36 year old female patient. The clinical presentation, histological features, and investigatory findings are discussed.

Malignant melanoma of the oral cavity
Jagadish Ebenezer
April-June 2006, 17(2):94-6
DOI:10.4103/0970-9290.29882  PMID:17051877
Oral malignant melanoma is a rare disease. The common sites of its occurrence are the palate and gingiva with the maxillary arch being affected 80% of the time. Because of their presence at relatively obscure areas in the oral cavity, most of the malignant melanomas of the oral cavity are diagnosed at a late stage. These lesions are associated with poor prognosis. The dental clinician must therefore carefully examine the head, neck, and oral cavity, and any pigmented lesion that may exhibit growth potential must be biopsied. This article describes a case of malignant melanoma that was present in the oral cavity and briefly reviews the relevant literature that explains the nature of this lesion.

AIDS awareness in an Indian metropolitan slum dweller : A KAP (knowledge, attitude, practice) study
M Kalasagar, B Sivapathasundharam, T Bertin A Einstein
April-June 2006, 17(2):66-9
DOI:10.4103/0970-9290.29889  PMID:17051870
OBJECTIVE : To assess the awareness and attitude towards AIDS and PLHA in slum dwellers of Chennai, an Indian metropolis by KAP (Knowledge, Attitude, Practice) study. METHODS : A cross sectional study was conducted in a representative sample of 650 subjects (400 females and 250 females), aged 15-45 years, by means of a questionnaire in the local dialect Tamil. RESULTS : The overall literacy rate was 64%, with males being 70% and females being 60% literate. 20% of males and 11% of females do not know about a disease called AIDS. Only 67% of males and 55% of females are aware of the sexual mode of transmission. 34% of males and 50% females opine that AIDS is also a hereditary disease. Also 45% of males and 62% of females feel that AIDS also spreads by air, fomites, or mosquito-bite. Only 30% of males and 22% females know about the possible symptoms of AIDS. 30% of males and 45% of females never ask for a new syringe if not provided, as they are totally unaware of its significance. 43% of males and 78% of females do not know about the risk of a barber's blade. 56% of males and 71% of females feel that AIDS can be treated at least by a traditional medicine. Lastly, 48% of males and 60% females prefer outcasting an AIDS patient from the slum. CONCLUSIONS : AIDS awareness in the slum dwellers of Chennai is very poor. Corresponding awareness in suburbs and rural areas will be much worse. Conventional IEC methods targeting general population via mass media are not reaching the slum dwellers, even in a metropolitan city. A specially designed targeted intervention is needed.

Microbial contamination of "In use" bar soap in dental clinics
PP Hegde, AT Andrade, K Bhat
April-June 2006, 17(2):70-3
DOI:10.4103/0970-9290.29888  PMID:17051871
Bar soap from 18 different dental clinics were investigated for microbial contamination, while it was "in-use". Of the 32 samples obtained from the bar soap, 100% yielded positive culture. A total of 8 different genera of organisms were isolated. Each bar soap was found to harbor 2-5 different genera of micro organisms. Heavily used soap had more micro organisms compared to less used soap. The microbial load of the "in-use" bar soap constituted a mixed flora of gram positive, gram negative, aerobes, anaerobes, and fungi. The results indicate that the bar soap under "in-use" condition is a reservoir of microorganisms and handwashing with such a soap may lead to spread of infection.

Treacher Collins syndrome encompasses a group of closely related defects of the head and neck. It is a rare syndrome characterized by bilaterally symmetrical abnormalities derived from the first and second brachial arches and the nasal placode. It is an autosomal dominant disorder and its occurence ranges from 1 in 25,000 to 1 in 50,000 live births. The facial appearance of these patients can be improved by either surgical or prosthetic rehabilitation. In this case report we are presenting the features of a 13-year-old boy with Treacher Collins syndrome. A multidisplinary approach was followed in managing the situation. The various treatment options and the steps involved in making an auricular prosthesis are also discussed.

DOI:10.4103/0970-9290.29885  PMID:17051874
Verrucous carcinoma is a rare warty variant of squamous cell carcinoma, most often seen in the oral cavity and larynx. Its occurrence in the sinonasal tract is rare. This tumor constitutes approximately 1% of all sinonasal neoplasms. The clinical presentation and the histopathological features of verrucous carcinoma are a subject of continuous discussion amongst diagnosticians and pathologists. A case with oral and nasal presentation of this tumor is reported here.
