The Knowledge and Awareness of Medical Emergencies and Management among Dental Students.

Background: Every dentist should anticipate being confronted with a medical emergency (ME), and one should always be ready to treat the most catastrophic ones.

Aim: This study aimed to assess the knowledge of dental clinical students of Tamil Nadu in the ME understanding and management to create awareness toward patient care.

Methodology: A total of 768 dental students, including final-year students and residents from different colleges, took part in the questionnaire-based cross-sectional study.

Assessment of Salivary Cortisol Concentrations as a Level of Stress Indicator among Individuals Undergoing Dental Extraction Procedure.

Background: Anxious patients tend to exaggerate the aversive events before the actual dental therapy. The anxiety and fear are the major factors that regulate cortisol levels.

Aim: Our study aims to estimate the salivary cortisol among patients subjected to dental extraction and correlate any existence between pre- and post-extraction cortisol levels and vital parameters compared to the control group.

Oxidation of Cysteinate Anions Immobilized in the Interlamellar Space of CaAl-Layered Double Hydroxide.

L-Cysteinate-intercalated CaAl-layered double hydroxide (LDH) was prepared by the co-precipitation method producing highly crystalline hydrocalumite phase with a well-pillared interlayer gallery. The obtained materials were characterized by X-ray diffractometry, IR as well as Raman spectroscopies. By performing interlamellar oxidation reactions with peracetic acid as oxidant, oxidation of cysteinate to cystinate in aqueous and cysteinate sulfenic acid in acetonic suspensions occurred.

Verrucous carcinoma in association with oral submucous fibrosis.

Oral verrucous carcinoma is a form of well differentiated squamous cell carcinoma characterized by exophytic over growth. It is slow growing and locally invasive tumor occurring in 6 th and 7 th decade of life. Smoking and chewing tobacco is found to be the most common etiological factor of verrucous carcinoma although oral leukoplakia may act as a predisposing factor.

In vivo native fluorescence spectroscopy and nicotinamide adinine dinucleotide/flavin adenine dinucleotide reduction and oxidation states of oral submucous fibrosis for chemopreventive drug monitoring.

Native fluorescence spectroscopy has shown potential to characterize and diagnose oral malignancy. We aim at extending the native fluorescence spectroscopy technique to characterize normal and oral submucous fibrosis (OSF) patients under pre- and post-treated conditions, and verify whether this method could also be considered in the monitoring of therapeutic prognosis noninvasively. In this study, 28 normal subjects and 28 clinically proven cases of OSF in the age group of 20 to 40 years are diagnosed using native fluorescence spectroscopy.
