Patient-centric outcome assessment of endodontic microsurgery using periapical radiography versus cone beam computed tomography: A randomized clinical trial.

Aim: This study aimed to evaluate whether utilizing additional cone beam computed tomography (CBCT) imaging has any effect on quality of life and healing outcome following periapical surgery compared with periapical radiographs (PR).

Methodology: The study was registered in ClinicalTrials.gov (NCT04333940).

Prevalence of dens invaginatus and palatogingival groove in North India: A cone-beam computed tomography-based study.

Aim: The aim of this study was to study the prevalence of dens invaginatus (DI) and palatogingival groove (PGG) in maxillary lateral incisors, and the occurrence of apical periodontitis in association with these anomalies in North Indian population.

Methodology: Maxillary lateral incisors in 163 cone-beam computed tomography scans were assessed to determine the presence of DI and PGG. Anomalies identified were then classified as per Oehler's and Gu's classification, respectively.

Factors causing stress in postgraduate dental students during COVID-19 pandemic: A cross-sectional survey.

Background: COVID-19 pandemic has impacted the academic and clinical training of postgraduate dental students. This study aimed to assess various factors causing psychological stress in them, and the extent of stress perception during pandemic.

Materials And Methods: In this cross-sectional study, 250 postgraduate students from nine dental colleges of Haryana and National Capital Region, India, responded to an online questionnaire sent electronically to them in September 2020, which included modified dental environment stress (DES) score, Perceived Stress Scale (PSS), and questions regarding COVID-associated stress (CAS).

Does rheumatic valvular heart disease affect right ventricular performance?

Aim: Right ventricular (RV) function often determines clinical outcome in patients with valvular heart disease. Though difficult to assess by echocardiography, Tei index is useful in its assessment. The aims of the study were to evaluate global RV function using the Tei index in patients with rheumatic heart disease and to observe if such abnormalities in RV function were reversible post-operatively.

Reconstruction of trileaflet pulmonary valve using autologous pericardium.

Tetralogy of Fallot with atretic or absent pulmonary valve may require pulmonary valve replacement or reconstruction. We propose a technique of reconstruction of a trileaflet valve at the level of the pulmonary annulus using untreated autologous pericardium. Six cases operated upon, using this technique, had trivial pulmonary regurgitation with a median gradient of 24 mmHg (18-38) across the newly created valve.
