    Abstract Background: The present “in vitro” study was done to observe the effects of high temperatures on teeth restored with different restorative materials and unrestored teeth. Aim and Objective: This study aims to investigate the nature of damage to unrestored and restored teeth subjected to high temperatures. The main objective of the study is to assess whether it could serve as an aid in identification of human dental remains in forensic odontology for cases of incineration by means of comparison between ante-mortem and post-mortem records. Materials and Methods: The present study was conducted on 125 extracted premolar teeth which were later on divided into five groups (25 premolar teeth each) as control group, group of teeth restored with class I amalgam restorations, group of teeth restored with class I composite/adhesive system restorations, group of teeth restored with glass ionomer restoration and group of teeth restored with metal ceramic crown restored teeth. The restored teeth were placed in a furnace and heated at a rate of 10°C/min. The effects of the predetermined 200°C, 400°C, 600°C, 800°C, 1000°C and 1200°C temperatures were examined macroscopically and then microscopically by means of a stereomicroscope. Data obtained in the present study was subjected to the statistical analysis using SPSS 18 software for one-way ANOVA andindependent t-test (paired). Result: The class I restorations made of amalgam could be identified till 1200°C because they maintain their shape despite the disintegration of the crowns along with PFM restoration with disintegration of remaining restorations along with tooth. Systematic approach toward the preservation of charred dentition, as at times could prove to be the best evidence for identification of those who are extensively burned. Conclusion: Pre-planned and systematic approach toward the preservation of charred dentition is important as at times it could act as a potential evidence for the identification of those who are severely burnt.

    Abstract Cloud computing facilitates the storage and management of huge volumes of data. It offers flexibility for retrieving the data anytime and anywhere. In recent years, storing data onto the cloud achieved fame among corporations as well as private users. Although, the cloud is drawing a lot of attention still there are data security, privacy, reliability and interoperability concerns that need to be taken care. To deal with these issues, cloud data encryption comes to the rescue. Encrypting the data before uploading it onto the cloud prevents unauthorized users from accessing the data. A lot of encryption algorithms have been developed to secure data stored on the cloud. In this paper, a novel cryptographic technique has been presented that uses client-side data encryption for encrypting the data before uploading it onto the cloud. It is a multifold symmetric-key cryptography technique which is based upon DNA cryptography. Besides presenting the detailed design of our approach, we have compared it with the existing symmetric-key algorithms (DNA, AES, DES and Blowfish). The experimental results illustrate that our proposed algorithm outperforms these traditional algorithms in terms of ciphertext size, encryption time and throughput. Hence, the newly proposed technique is more efficient and offers better performance.

    Abstract Introduction: Thoracic Paravertebral Block (TPVB) appears promising for reduction of postoperative pain in Modified Radical Mastectomy (MRM). Various combinations of local anaesthetics and adjuvants have been tried in TPVB but search for an ideal combination is still on. Aim: To evaluate analgesic efficacy of clonidine (1 μg/kg) as adjuvant with different concentrations of ropivacaine (0.35%, 0.2%) for TPVB in MRM surgery. Materials and Methods: This randomised double blind comparative clinical study was carried out in a tertiary care centre in Southern Rajasthan from January 2019 to March 2020, clinical study, 120 American Society of Anaesthesiologists (ASA) grade I, II patients aged 18-60 years female patients undergoing MRM surgery were randomised into three groups- RP, RC and LDRC to receive 0.35% Ropivacaine 19 mL, 0.35% Ropivacaine 19 ml+Clonidine (1 μg/kg) and 0.2% Ropivacaine 19 ml+Clonidine(1 μg/kg) diluted upto total 20 ml with normal saline, respectively. TPVB was performed at T4 level as single injection followed by administration of general endotracheal anaesthesia. The primary outcome measured was duration of analgesia. Secondary outcomes measured included consumption of rescue analgesic, Visual analog scale and perioperative haemodynamic parameters. Quantitative and qualitative data were analysed using Analysis of Variance (ANOVA) and Chi-square test respectively. p<0.05 was considered statistically significant. Results: Mean duration of analgesia was prolonged in clonidine groups RC and LDRC (811.5±110.99 and 753±119.76 min, respectively) as compared to group RP (400.125±108.13 min), although no statistically significant difference was noted between group RC and LDRC. Similar observations were noted when total dose of rescue analgesic in group RC (82.50±7.21 mg) and LDRC (99.38±35.57 mg) was compared to group RP (142.50±53.169 mg) as well as when total number of rescue analgesic doses in group RC (1.10±0.496) and group LDRC (1.32±0.474) were compared to group RP (1.92±0.694).
