Allergic contact stomatitis caused by a polyether dental impression material.

A 50-year-old female presented with a 12-year history of increasingly severe symptoms affecting the oral mucosa following dental work. On the first occasion, the patient noted a tingling sensation in her lips and tongue on the day after dental work. She experienced worsening symptoms over the next few years, noticing that they always occurred around 24 hr after having crowns replaced or a new c...

Effect of moisture on polyether impression materials.

Effect of mixing techniques on bacterial attachment and disinfection time of polyether impression material

OBJECTIVE The aim of this study was 2-fold. The first aim was to evaluate the effects of mixing technique (hand-mixing or auto-mixing) on bacterial attachment to polyether impression materials. The second aim was to determine whether bacterial attachment to these materials was affected by length of exposure to disinfection solutions. MATERIALS AND METHODS Polyether impression material samples...

Effect of Cervical Relining of Acrylic Resin Copings on the Accuracy of Stone Dies Obtained Using a Polyether Impression Material

The purpose of this study was to evaluate the accuracy of the respective dies after polyether elastomeric procedure in the presence or absence of cervical contact of the acrylic resin shell with the cervical region, establishing a comparison to dies obtained with stock trays. This study consisted of three groups with 10 specimens each: 1) acrylic copings without cervical contact, (cn); 2) acryl...

Antibacterial and antifungal properties of polyether impression materials.

The aim of this study was to evaluate the antibacterial and antifungal properties of polyether impression materials using the agar diffusion test. Three different types of polyether impression materials (P2, Penta Soft and Penta) were tested to determine their ability to inhibit the growth of Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. The areas o...
