Abstract
Meloxicam (MLX) is currently used in the therapeutic management of both acute and chronic inflammatory disorders such as pain, injuries, osteoarthritis, and rheumatoid arthritis in both humans and animals. Gastrointestinal toxicity and occasional renal toxicity were observed in patients taking it for a long-term period. Meloxicam's late attainment of peak plasma concentration results in a slow onset of action. The goal of the current study was to prepare and characterize chitosan encapsulated meloxicam nanoparticles (CEMNPs) with high bioavailability and less gastro intestinal toxicity in order to prevent such issues. The size of the prepared CEMNPs was approximately 110-220 nm with a zetapotential of +39.9 mV and polydispersity index of 0.268, suggesting that they were uniformly dispersed nanoparticles. The FTIR and UV-Vis spectroscopy have confirmed the presence of MLX in the prepared CEMNPs. The pharmacokinetics have been studied with three groups of male Wistar rats receiving either of the treatments, viz., 4 mg·kg-1 of MLX and 1 or 4 mg·kg-1 of CEMNPs. Plasma samples were collected until 48 h post administration, and concentrations of MLX were quantified by using reverse (C18) phase HPLC. Non-compartmental analysis was applied to determine pharmacokinetic variables. Upon oral administration, the maximum concentration (Cmax) was reached in 4 h for CEMNPs and 6 h for MLX. The mean area under the plasma MLX concentration-time curve from 'zero' to infinity (AUC0-∞), half-life (t1/2β), and mean resident time (MRT) of 1 mg·kg-1 of CEMNPs was 1.4-, 2-, and 1.8-fold greater than 4 mg·kg-1 of MLX. The prepared CEMNPs demonstrated quicker absorption and prolonged release along with a significant improvement in the bioavailability of MLX, paving a prospective path for the development of drugs with enhanced bioavailability with less side effects.

Abstract
Objective: Gingival recession (GR) is a common manifestation in most populations, and is considered as an early sign of periodontal disease. GR is an intriguing condition where various factors play an important role in its etiology. Only few studies have been undertaken to assess the prevalence and risk factors for GR in patients visiting dental hospitals. The aim of this study is not only to estimate prevalence, severity, and extent of GR in hospital population, of Vishnu Dental College, Bhimavaram, Andhra Pradesh, India, but also to assess the potential risk factors for the same. Materials and Methods: In this study, 2837 patients were examined of which 627 were included into the study. The age range was 16-80 years. Subjects were interviewed using a structural questionnaire, and full mouth clinical examination was done to assess recession. Results: Of all subjects examined 45.6%, 16.2% of individuals and 13%, 4.8% of teeth per individual showed GR >3 mm. Prevalence and severity of recession was correlated with age. Recession was present but recession threshold ≥3 and ≥5 mm affected only small percentage of teeth in subjects younger than 45 years. Mandibular incisors showed the highest prevalence of GR ≥1 mm with 61% of teeth being affected. Smoking and presence of supragingival calculus were most significantly associated localized and generalized recession. Conclusion: Prevalence of periodontal disease is high among this population based on the presence of gingival recession in most the individuals. High prevalence of GR is significantly associated with supragingival calculus and smoking habits. This suggests a need to improve their periodontal condition through education, motivation, and improving their periodontal health.
