The Accuracy of Four Impression-making Techniques in Angulated Implants Based on Vertical Gap
Conclusion: Vertical gap measurementsshowed that metal splinted impression coping and fabricated acrylic resin transfer cap techniques produced quite more accurate impressions than closed-tray snap-fit transfer and open-tray nonsplinted impression coping techniques do. The fabricated acrylic resin transfer cap technique seems to be a reliable impression-making method. (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Salivary Chemical Factors in Relation with Oral Cancer in Smokers and Non-Smokers: a Literature Review
Squamous cell carcinoma of oral cavity is of malignant tumors, which causes cancerous complications. DNA damage, mainly because of products of oxidative stress like reactive oxygen species, is a frequent mutagenic that triggers carcinoma. Smoking increases the probability of cancer incidence. Saliva is the first biological medium to interact with external compounds, especially smoking substances. The present study overviews the salivary level of some remarkable compounds in relation with smoking and squamous cell carcinoma.To collect data, English literature was searched in databases including PubMed, ScienceDirect and Goo...
