The human body comprises molecules; hence, the availability of molecular nanotechnology will permit dramatic progress to address medical problems and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine could develop devices that are able to work inside the human body in order to identify the early presence of a disease, and to identify and quantify toxic molecules and tumor cells, for example. Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, including tissue engineering and, ultimately, dental nanorobots. This review is an attempt to highlight the possible applications of nanotechnology and the use of nanomaterials in dentistry.

The adenoid cystic carcinoma is a relatively rare epithelial tumor of the major and minor salivary glands, accounting for about 1% of all malignant tumor of the oral and maxillofacial region. Although it presents a widespread age distribution, peak incidence occurs predominantly among women, between the 5th and 6th decades of life. The clinical and pathological findings typical of this tumor include slow growth, perineural invasion, potential local recurrence and distant metastasis. Histopathologically it is composed of basaloid cells with primarily myoepithelial/basal cell differentiation. It presents three patterns, cribriform, tubular and solid; the solid type is related to a poor prognosis contrary to the cribriform type, which has a better prognosis. Surgical excision with wide margins is the treatment of choice, if it metastasizes to lymph nodules, post surgical radiotherapy is recommended. We presented herein the case of a 45 year old female patient who presented a palatal lesion, which was treated with surgery and radiotherapy as an additional treatment. We also described a brief literature review of adenoid cystic carcinoma. © 2011 Elsevier Ltd. All rights reserved.

To retrospectively analyse the frequency and distribution of various biopsied lesions of the gingiva among patients attending a dental teaching institution in Karnataka state in India. Data collected from 153 gingival biopsies referred to the Department of Oral Pathology, Yenepoya Dental College in Mangalore, Karnataka state, India during a 5-year period from 2004-2008 were utilised for the purpose of this study. Lesions were categorised by their type and analysed for age, sex and location. Non-neoplastic lesions accounted for 51% while neoplastic and potentially malignant lesions accounted for 49% of the lesions. The most common non-neoplastic lesion was pyogenic granuloma (42.3%), the most common benign neoplasm was fibroma (34.5%) and the most common malignant lesion was squamous cell carcinoma (82.6%). Among all the lesions, the most common was squamous cell carcinoma (24.8% of all the lesions). Unlike in previous studies, squamous cell carcinoma was the most common gingival lesion. The proportion of malignant and potentially malignant lesions was also higher among subjects in the present study than in other populations. Hence, public oral health programmes need to be formulated to better tackle the burden of these diseases.

Objective: To assess the relationship between exposure to different drinking water fluoride levels and children's intelligence in Madhya Pradesh state, India. Materials and Methods: This cross-sectional study was conducted among 12-year-old school children of Madhya Pradesh state, India. The children were selected from low (< 1.5 parts per million) and high (≥1.5 parts per million) fluoride areas. A questionnaire was used to collect information on the children's personal characteristics, residential history, medical history, educational level of the head of the family, and socioeconomic status of the family. Levels of lead, arsenic, and iodine in the urine and the levels of fluoride in the water and urine were analyzed. The children′s intelligence was measured using Raven's Standard Progressive Matrices. Data analysis was done using the chi-square, one way analysis of variance, simple linear regression, and multiple linear regression tests. P value <0.05 was considered statistically significant. Results: Differences in participant's sociodemographic characteristics, urinary iodine, urinary lead, and urinary arsenic levels were statistically not significant (P>0.05). However, a statistically significant difference was observed in the urinary fluoride levels (P 0.000). Reduction in intelligence was observed with an increased water fluoride level (P 0.000). The urinary fluoride level was a significant predictor for intelligence (P 0.000). Conclusion: Children in endemic areas of fluorosis are at risk for impaired development of intelligence.

Helicobacter pylori (H. pylori) infection is one of the most common bacterial infections in humans. Although H. pylori may be detected in the stomach of approximately half of the world's population, the mechanisms of transmission of the microorganism from individual to individual are not yet clear. Transmission of H. pylori could occur through iatrogenic, fecal-oral, and oral-oral routes, and through food and water. The microorganism may be transmitted orally and has been detected in dental plaque and saliva. However, the role of the oral cavity in the transmission and recurrence of H. pylori infection has been the subject of debate. A large number of studies investigating the role of oral hygiene and periodontal disease in H. pylori infection have varied significantly in terms of their methodology and sample population, resulting in a wide variation in the reported results. Nevertheless, recent studies have not only shown that the microorganism can be detected fairly consistently from the oral cavity but also demonstrated that the chances of recurrence of H. pylori infection is more likely among patients who harbor the organism in the oral cavity. Furthermore, initial results from clinical trials have shown that H. pylori -positive dyspeptic patients may benefit from periodontal therapy. This paper attempts to review the current body of evidence regarding the role of dental plaque, saliva, and periodontal disease in H. pylori infection. © 2014 Baishideng Publishing Group Inc.
