Risk of tumor cell seeding through biopsy and aspiration cytology
K Shyamala, HC Girish, Sanjay Murgod
January-April 2014, 4(1):5-11
DOI:10.4103/2231-0762.129446  PMID:24818087
Cancer cells, besides reproducing uncontrollably, lose cohesiveness and orderliness of normal tissue, invade and get detached from the primary tumor to travel and set up colonies elsewhere. Dislodging neoplastically altered cells from a tumor during biopsy or surgical intervention or during simple procedure like needle aspiration is a possibility because they lack cohesiveness, and they attain the capacity to migrate and colonize. Considering the fact that, every tumor cell, is bathed in interstitial fluid, which drains into the lymphatic system and has an individualized arterial blood supply and venous drainage like any other normal cell in our body, inserting a needle or a knife into a tumor, there is a jeopardy of dislodging a loose tumor cell into either the circulation or into the tissue fluid. Tumor cells are easier to dislodge due to lower cell-to-cell adhesion. This theory with the possibility of seeding of tumor cells is supported by several case studies that have shown that after diagnostic biopsy of a tumor, many patients developed cancer at multiple sites and showed the presence of circulating cancer cells in the blood stream on examination. In this review, we evaluate the risk of exposure to seeding of tumor cells by biopsy and aspiration cytology and provide some suggested practices to prevent tumor cell seeding.

RS Senkutvan, Sanjay Jacob, Anila Charles, Vaishali Vadgaonkar, Suruchi Jatol-Tekade, Parag Gangurde
January-April 2014, 4(1):12-16
DOI:10.4103/2231-0762.130921  PMID:24818088
Aim: The high incidence of nickel (Ni) allergy and the increasing use of Ni-containing dental biomaterials have been of growing concern. The purpose of this investigation was to analyze and evaluate the rate of Ni ion release from different types arch wires used in orthodontics. Materials and Methods: Four groups of arch wires (nickel titanium [NiTi], SS, Cu NiTi and ion implanted NiTi) with twelve samples were stored in artificial saliva with a pH 5.6-7.0 thermostated at (36.5°C) and tested at different intervals i.e., 7th day, 14th day, and 21st day. The amount of Ni and Ti ions released from the sample were evaluated using an atomic adsorption spectrophotometer. The solution was replaced with a fresh bottle to avoid sediments. Results: Statistical analysis was performed by nonparametric tests (Student's paired t-test, one-way analysis of variance and multiple comparison test by Tukey "Honestly significant difference"). The statistical package SPSS PC plus (version 4.0.1) was used for data processing and statistical analysis. Results showed significantly statistical influence on the release amount of Ni and Ti ions. Large variation in concentration of Ni released from brackets and bands combined. However, the amount of Ni ions released in all test solutions diminished with time and was below the critical value necessary to induce allergy and below daily dietary intake level. Conclusions: The daily release of NiTi, SS, Cu NiTi and ion implanted NiTi by an orthodontic appliance in acid pH, particularly favorable to corrosion, was well below that ingested with a normal daily diet. It is therefore concluded that the quantities of metal ions released in our experimental conditions should not be cause for concern in utilizing the appliance.

DOI:10.4103/2231-0762.131269  PMID:24818098
Aims: The aim of this study is to evaluate the expression of human papilloma virus (HPV) in oral squamous cell carcinoma (OSCC) and to correlate the association of HPV in histological grades of OSCC using p16 (p16INK4a) immunohistochemistry (IHC). Subjects and Methods: This study consists of 30 histological diagnosed cases of OSCC (10-well-differentiated oral squamous cell carcinoma [WDOSCC], 10-moderately differentiated oral squamous cell carcinoma [MDOSCC] and 10-poorly differentiated oral squamous cell carcinoma [PDOSCC]). The sections were subjected to IHC procedure using p16. Two parameters in immunohistochemical p16 expression were evaluated by 3 observers based on the criteria by Galgano M. Tetal (2010) (a) percentage of p16 positive cases (b) pattern of p16 staining in various grades of OSCC. Statistical Analysis Used: Kappa test. Results: Totally, 30 samples of 0SCC, p16 positivity was noted in 26/30 (86.66%). Of 26 positive cases, p16 staining was positive in 7/10 (70%) of WDOSCC, 9/10 (90%) in MDOSCC and, 10/10 (100%) PDOSCC. Incidentally, we also found single dispersed cell staining in WDOSCC, patchy staining in MDOSCC and more diffuse staining pattern predominant in PDOSCC. Conclusions: Our study revealed an association between HPV and OSCC. Diffuse staining pattern was noted in PDOSCC, which in turn depicts the increase viral overload, which might have an influence on its aggressive behavior.

January-April 2014, 4(1):22-28
DOI:10.4103/2231-0762.127211  PMID:24818090
Objective: The objective of present study was to qualitatively and quantitatively evaluate and compare the effect of two ceramic finishing systems and diamond polishing paste on surface texture of two ceramic materials. Methodology: The 40 test specimens were randomly divided into two main groups (Group I and Group II). Which were subsequently veneered with feldspathic porcelain and fluorapatite leucite porcelain systems respectively. The samples in Test group I and Test group II were subjected to different abrasion and finishing systems (Soft Lex and White silicon and grey rubber respectively). The surface roughness of all the four groups was assessed qualitatively using the scanning Electron Microscope and profilometer. Results: The surface roughness of Feldspathic and fluorapetite porcelain increased after abrasion and finishing as compared to auto-glazed porcelin. The surface roughness was more in grey rubber disc group (Gp Ib) as compared to the soft lex disc groups. After polishing with the diamond paste, there was reduction in the surface roughness of both the disc groups. The Mean Ra values of the Feldspathic porcelain at three intervals were 0.52 ± 0.06, 0.54 ± 0.06, 0.32 ± 0.06 and 0.50 ± 0.04, 1.25 ± 0.10, 0.45 ± 0.6 respectively for grey rubber disc and soft lex groups. The Mean Ra values of Fluorapetite porcelain at three intervals were 0.40 ± 0.06, 0.52 ± 0.06, 0.30 ± 0.03 and 0.41 ± 0.04, 1.17 ± 0.09, 0.39 ± 0.07 respectively for grey rubber disc and soft lex groups. Discussion and Conclusion: The surface roughness was less in the polished samples as compared to the auto-glazed porcelain. The findings were more reinforcing in the soft lex group as compared to the white/grey rubber disc group. Between the two porcelain systems, the Fluorapatite leucite porcelain specimens exhibited better surface smoothness than feldspathic porcelain.

Background: Frail and functionally dependent elderly people, living in institutions, have difficulties in accessing dental care. Hence, the present study aims to determine the relationship between subjective need and the equivalent clinical findings in an attempt to understand the factors that contribute to individual's perception of the need for dental care among institutionalized adults in Vijayawada. Materials and Methods: A cross-sectional study is conducted in all old age homes in Vijayawada. A total of 182 subjects were interviewed with a questionnaire consisting of demographic details, dental behavior (last visit, reason for the last visit), and self-rating of oral health and impact of oral problems, followed by the clinical examination for oral mucosal condition, dentition status and treatment needs, prosthetic status and treatment needs, and periodontal status by using World Health Organization proforma. Results: Results showed that normative needs of subjects are significantly more than the self-perceived needs. Response of subjects regarding their present condition of mouth and teeth is 65.4% of subjects reported good and 0.5% reported poor, with respective to perceived oral symptoms 61.9% of subjects' complaints of hypersensitivity and 23.1% of subjects were having toothache and 80.5% subjects are having difficulty in eating. The overall prevalence of complete Edentulous and require complete denture was 12.1%, and 60.4% required partial denture. Conclusion: About half of the participants confirmed need for problem-oriented dental care. The main reason for the problems faced by the institutionalized people is due to lack of teeth which could be prevented by appropriate care.
