Clinical evaluation of restored maxillary incisors: veneers vs. PFM crowns

Article Abstract:

Porcelain laminate veneer restorations appear to be associated with less gum disease and may be more clinically acceptable and esthetic than porcelain-fused-to-metal (PFM) crowns. Researchers evaluated restorations and periodontal health in 60 dental patients. Thirty patients had PFM crowns and 30 had veneers in two upper front teeth. The margins of most veneers were placed above the gumline while the margins of most PFM crowns were placed below the gumline. As margin placement moved closer to and below the gumline, signs of periodontal disease increased. Patients with PFM crowns had greater gum inflammation and bleeding than patients with veneers. Veneers matched the color and surface of the adjacent teeth more closely than PFM crowns. Five percent of PFM margins and none of the veneer margins had secondary cavities.

Caries prevention during pregnancy: results of a 30-month study

Article Abstract:

A simple treatment to reduce mutans streptococci levels in the saliva of pregnant women may prevent tooth decay in the women as well as in their babies. Mutans streptococci is the bacterium most commonly associated with dental cavities. Researchers randomly assigned 65 pregnant women with excessive amounts of mutans streptococci in their saliva to use a fluoride and chlorhexidine mouthwash daily or fluoride only (the Control group). Chlorhexidine reduced the level of salivary mutans streptococci and prolonged the rate of streptococci colonization in the infants.

The clinical performance of laboratory-fabricated crowns placed on first permanent molars with developmental defects

Article Abstract:

Gold, composite or ceramic crowns can be used to repair developmental enamel defects in young children. Usually such defects are treated with stainless steel crowns, but some children become allergic to the nickel and chromium in stainless steel.
