Occlusal Vertical Dimension and Its Association with Length of Thumb: An Original Research.

Introduction: Establishing an accurate vertical dimension at occlusal (VDO) is a challenge. Hence, we aim to find the association between the VDO and the Thumb Length (TL).

Materials And Methods: We piloted an observational study by evaluating the VDO and the TL among the Dravidian and Aryan ethnicities with 200 volunteers.

Assessment of Failure Rate of Fixed Partial Dentures: A Clinical Study.

Introduction: The most common for the replacement for the teeth are the partial dentures. Hence, in our study, we analyzed the failure rates of the fixed partial dentures (FPDs).

Materials And Methods: We conducted a retrospective study from the institutional record and analyzed 150 subjects.

Middle East Authors' Contribution to the 's Publications in the Past 20 years (2000-2020).

Background: This study aimed to evaluate the Middle East (ME) countries' contribution to (JOA)'s publications in the past 20 years.

Methods: All articles published in JOA from 2000 to 2020 were evaluated for the contribution prevalence of ME countries' authors, which were divided into category I, if all the authors were affiliated to ME institutions, and category II, if at least one coauthor affiliated to ME institutions was listed in the articles with other international authors.

Results: A total of 7837 original articles were evaluated.

Laser Myringotomy Versus Ventilation Tubes In Otitis Media With Effusion.

Background: Otitis media with effusion (OME) is a leading cause of difficulty in hearing in paediatric population. Otitis media with effusion must be detected and managed early to prevent conductive hearing loss in children. It was aimed to compare results of laser myringotomy and ventilation tube insertion, in terms of hearing improvement and recurrence of Middle ear effusion (MEE).

Analysis of Eyring-Powell fluid in helical screw rheometer.

This paper aims to study the flow of an incompressible, isothermal Eyring-Powell fluid in a helical screw rheometer. The complicated geometry of the helical screw rheometer is simplified by "unwrapping or flattening" the channel, lands, and the outside rotating barrel, assuming the width of the channel is larger as compared to the depth. The developed second order nonlinear differential equations are solved by using Adomian decomposition method.
