Evaluation of surface detail reproduction, dimensional stability and gypsum compatibility of monophase polyvinyl-siloxane and polyether elastomeric impression materials under dry and moist conditions.

Objectives: This in vitro study was designed to compare polyvinyl-siloxane (PVS) monophase and polyether (PE) monophase materials under dry and moist conditions for properties such as surface detail reproduction, dimensional stability, and gypsum compatibility.

Materials And Methods: Surface detail reproduction was evaluated using two criteria. Dimensional stability was evaluated according to American Dental Association (ADA) specification no.

Pyogenic granuloma near the midline of the oral cavity: A series of case reports.

Pyogenic granuloma (PyG) is a common cause of swelling in the oral cavity during pregnancy and also as an exaggerated response to any minor trauma. The condition is frequently associated with periodontal pain and discomfort, in some cases interfering with mastication and creating esthetic problems. Six patients reported to the Department of Periodontics with gingival overgrowth in the lower anteriors.

Candida in oral pre-cancer and oral cancer.

Since the initial reports of an association between candidiasis with oral pre-cancer and cancer, various theories have been debated regarding the role of candida in development and transformation of oral pre-malignancies.
