Constructing direct porcelain laminate veneer provisionals
Article Abstract:
Dentists can use a simple technique to make provisionals for teeth prepared for porcelain laminate veneers (PLVs). Provisionals are temporary restorations used to protect teeth until a permanent prosthesis is fabricated and placed. A 26-year-old woman chipped a PLV on a front tooth. Her dentist applied wax to the chipped tooth to correct its shape and took an impression of the front teeth using a transparent material in a clear tray. The PLVs were removed, the front teeth were acid-etched, and a second impression of the front teeth was taken for dental laboratory use. The dentist retrieved the first impression tray and applied a composite material to the outer surface of the front teeth. The impression was replaced in the mouth, light cured, and the tray was removed. The temporary restorations remained on the teeth and were adjusted as needed. The dentist later removed the temporary restorations and bonded the PLVs to the enamel of the front teeth.

Treating caries as an infectious disease
Article Abstract:
Dentists should assess each patient's risk of cavities and select appropriate preventive or therapeutic interventions. Rates and patterns of dental decay vary in the population and interventions should meet patient's unique needs. Dentists can use a combination of diagnostic tools including visual examinations, x-rays, the dental history, and bacteriologic assessments to identify decay and determine the patient's risk of cavities. Because cavities form in the presence of decay-producing bacteria, foodstuffs to support bacterial growth, and susceptible tooth structure, dentists can modify these conditions to prevent or arrest decay. Risk-based interventions include educational reinforcement, sealants, fluorides, dietary counseling, and antimicrobial agents. At follow-up visits, dentists should reevaluate the patient's risk of cavities.

Adjunctive caries control: in overdenture abutment teeth: a new modality
Article Abstract:
Dentists can seal the exposed dentin in the retained roots of teeth that support dentures to prevent cavities. A 40-year-old man had complete upper dentures that were supported by the retained roots of two teeth. During a dental check-up, his dentist discovered and filled cavities in a tooth root. The dentist decided to seal the exposed dentin in the retained roots of the teeth that support the dentures to prevent decay. He applied an acid etchant and priming agents to the dentin. A primer was applied around the metal attachments inside the mouth that secured the denture. This preparation was necessary to enable the sealant to bond to the dentin and metal. The process was completed after the dentist applied a thin layer of resin sealant to the primed dentin and metal.
