#1
Mohamed S Bamashmous
BACKGROUND: Clinicians often ask, "Veneer or no to veneer?" Clinicians usually think of porcelain veneers for cases in which patients are dissatisfied with their teeth shape. Interproximal reduction can change teeth's shape and appearance within the enamel to improve gingival contour, eliminate black gingival triangles, and correct the Curve of Spee. AIM: Our aim is to present to clinicians the option of reshaping and interproximal reduction (IPR) as a valid alternative to porcelain veneers...

The varying levels of salivary secretory immunoglobulin A (SIgA) usually determine the progression of caries. The present study was aimed to determine the correlation between SIgA and mutans-specific antigen SIgA in children having different caries status. Scanning electron microscopic analysis was also completed to correlate the results. MATERIALS AND METHODS: This study comprised 60 subjects, who were divided into three groups depending on caries status...
