Butyrylcholinesterase: An economical marker of disease activity in oral squamous cell carcinoma before and after therapy.

INTRODUCTION: Biomarkers which can predict disease progression and serve as prognostic indicators are necessary for better management of oral cancer. Studies have shown that Cholinesterase plays an important role in cellular proliferation, differentiation and may have a possible involvement in tumor growth. AIM AND OBJECTIVE: The present study is aimed to determine the utility of serum Butyrylcholinesterase (BChe) levels as a marker for progression of oral squamous cell carcinoma (OSCC) in relation to the grade of the tumor and to determine if any variation occurred in the levels of BChe before and after therapy. MATERIALS AND METHODS: A total of 120 patients were included in the study and divided into two groups as Group A-30 patients (healthy individuals) and Group B-90 cases of histopathologically diagnosed OSCC. The blood sample was collected before surgery, re-collected after the completion of radiotherapy (i.e., 3 and 6 months postsurgery) and analyzed biochemically for the concentration of BCh. STATISTICAL ANALYSIS: Paired t-test, ANOVA, and post hoc test (Bonferroni) were used for determining the statistical significance. RESULTS: BChe levels were lower in OSCC (2940.32-1405.50 u/l when compared with controls (11149.60-11243.07 unit/l) and this difference was statistically significant. Postoperatively at 3 months, the serum BChe levels of OSCC patients increased almost two-fold compared to the preoperative values, and this difference was also statistically significant (P = 0.000) After 6 months, these levels further increased but did not reach those of controls. CONCLUSION: BChe can be used as an inexpensive, easy to use, noninvasive biomarker for the evaluation of disease-free survival in OSCC patients.

Comparative Evaluation of Platelet Rich Fibrin and Dehydrated Amniotic Membrane for the Treatment of Gingival Recession- A Clinical Study.

INTRODUCTION: The main objective of any therapeutic intervention aimed at root coverage is to restore the tissue margin to the cemento-enamel junction and to regenerate the lost periodontium. AIM: To compare the effectiveness of Platelet Rich Fibrin (PRF) and Amniotic Membrane (AM) in the treatment of gingival recession by Coronally Advanced Flap (CAF) Technique. MATERIALS AND METHODS: Thirty systemically healthy patients who met inclusion-exclusion criteria were selected. After Phase-I therapy, patients were randomly allocated to one of the groups; PRF (Group-A) and Amnion Group (Group-B). Clinical parameters like Plaque Index (PI), Recession Depth (RD) and Width of Keratinized Gingiva (WKG) were measured on the baseline day, three months and six months postoperatively. Mann-Whitney test and Wilcoxon signed ranks test were applied for intergroup and intragroup comparisons respectively. RESULTS: Intergroup comparison between platelet rich fibrin and amniotic membrane showed statistically insignificant difference in the recession depth and width of keratinized gingiva at three and six months postoperatively. CONCLUSION: Both the membranes were equally effective in terms of recession coverage and increase in width of keratinized gingiva.

Impact of Bariatric Surgery and Diet Modification on Periodontal Status: A Six Month Cohort Study.

BACKGROUND: Nutrition is an essential component of oral health and improper nutrition is an important aetiological factor in the development of obesity as well. AIMS AND OBJECTIVES: This study aimed to evaluate effect of diet modification and oral hygiene maintenance after bariatric surgery on the periodontal status of Class III and IV obese patients. MATERIALS AND METHODS: Two hundred and twenty four patients between the age ranges of 18 -64 years, from both sexes, were subjected to complete periodontal examination prior to bariatric surgery and 6 months post surgery. Patients were advised diet modification which included more fibrous food intake & decreased intake of soft and sugary food along with supragingival scaling & oral health care regime after bariatric surgery with a 6 month follow up. No periodontal surgical intervention was performed. RESULTS: The patients showed a mean differences in the bleeding score, plaque and gingival index which was found to be statistically significant (p<0.001). The improvement in clinical attachment level and probing pocket depth before and after surgery were found to be statistically insignificant (p>0.05). CONCLUSION: Thus we conclude that fibrous diet along with good periodontal care can help to improve the oral hygiene status of patients undergoing bariatric surgery, even if periodontal surgical intervention is not performed resulting in freedom from periodontitis, thus improving quality of life of the patient.
