Abstract: Background: Retention is a key determinant of success in complete denture prosthodontics, critically influenced by the accuracy of impression techniques and the materials employed. Aim: To compare and evaluate the retentive forces required to dislodge maxillary special trays fabricated using different final impression materials following border moulding. Materials and Methods: This in vivo study involved 10 completely edentulous patients. After standardized border moulding, three final impressions were made per patient using zinc oxide eugenol, zinc oxide non-eugenol, and addition silicone monophase.......

Key Word: Denture retention, final impression materials, zinc oxide eugenol, addition silicone, border moulding, complete denture.

Abstract: The world was profoundly affected by the COVID-19 pandemic, which started in 2019 as an outbreak of a new respiratory disease in Wuhan, China. The World Health Organization declared it a global pandemic after the outbreak rapidly grew out of control and was caused by a virus belonging to the coronavirus family. In addition to putting a strain on public health systems, COVID-19 also changed daily life and upended economy. There were differing views on how it should be handled, particularly with relation to the vaccines that were created and made available in less than a year.......

Abstract: Background: Plantar fasciitis is one of the most common causes of heel pain, resulting from inflammation and microtears of the plantar fascia-a thick fibrous band of connective tissue that supports the medial longitudinal arch of the foot and absorbs shock during ambulation. The condition predominantly affects individuals between the ages of 40 and 60 and is especially prevalent among runners, obese individuals, and those with occupations requiring prolonged standing or walking on hard surfaces [1,2]. The pathophysiology involves repetitive stress leading to collagen degeneration at the fascia’s origin on the medial calcaneal tubercle.......

Key Word: Plantar fasciitis, Heel pain, GFC injection, USG (Ultrasonography), NRS(Numerical Rating Scale).
