Observations have suggested that during the coronavirus disease 2019 pandemic, because of lockdown students who are in process of doing their thesis related work exhibit responses related to stress due to the fear of spread contagion and because of various limitations in performing thesis work, especially patient-oriented collection of data and clinical work. The present study aimed to determine various problems faced by the students in postgraduate courses for completing their thesis during pandemic. This was a prospective and cross-sectional study based on a questionnaire.

Comparative Evaluation of Primary Stability of Two Different Types of Orthodontic Mini-Implants.

Background: The mini-implants introduced new possibilities of adequate anchorage in orthodontics. Furthermore, due to its small size, it can even be placed at relatively difficult sites with ease. Removal torque should be high to prevent implant unscrewing.

Assessment of Effectiveness of Erbium:Yttrium-Aluminum-Garnet Laser, GentleWave Irradiation, Photodynamic Therapy, and Sodium Hypochlorite in Smear Layer Removal.

Aim And Objective: To compare the effectiveness of erbium:yttrium-aluminum-garnet laser, GentleWave irradiation, photodynamic therapy (PDT), and sodium hypochlorite in smear layer removal and dentin permeability with a scanning electron microscope (SEM).

Materials And Methods: Seventy-five recently extracted single-rooted teeth (maxillary second premolars) were randomly divided into 5 groups of 15 each. Group I teeth was the control group in which conventional root canal preparation (RCP) [17% ethylenediaminetetraacetic acid (EDTA)] was done without laser irradiation, group II teeth underwent RCP and GentleWave™ treatment, group III teeth were subjected to Er:YAG laser irradiation, group IV uses low-level 660 nm (PDT), and group V samples were irrigated with 5.

Psychological Impact on Maxillofacial Trauma Patients - An Observational Study.

Facial disfigurement due to trauma is very common as the face is a prominent part of the body and is susceptible to injuries. A protocol for the diagnosis and intervention for psychological problems of trauma patients should be implemented in the Indian hospitals as they lack policies for assessing the mental status of such patients. This study was conducted to analyze and determine the psychological implications and need for mental health services of maxillofacial trauma patients.

A Comparative Assessment of Peri-implant Soft and Hard Tissues with Immediate and Delayed Implants.

Aim And Objective: This study was done to assess peri-implant soft tissues and hard tissues in immediate and delayed titanium implants cases.

Materials And Methods: This study was conducted on 84 patients who were randomly divided into two groups. Group I was immediate implant group (42 patients) and group II was delayed implant group (42 patients).

Bisphenol A in dental sealants and its estrogen like effect.

Bisphenol A or BPA-based epoxy resins are widely used in the manufacture of commercial products, including dental resins, polycarbonate plastics, and the inner coating of food cans. BPA is a precursor to the resin monomer Bis-GMA. During the manufacturing process of Bis-GMA dental sealants, Bisphenol A (BPA) might be present as an impurity or as a degradation product of Bis-DMA through esterases present in saliva.
