After excision of an asymptomatic mandibular lesion that had tested positive for serosanguineous fluid, microscopic examination revealed a hybrid focal cemento-osseous dysplasia and aneurysmal bone cyst, a previously unreported association. Although fibrous-osseous lesions do not require intervention, surgical excision is recommended when they are associated with cysts.

When gingival chemical burns developed in a patient who failed to follow manufacturer’s instructions to rinse with water following the use of a tooth whitening mouthrinse, successful resolution of the injury was achieved through product withdrawal and saline rinses. Patients should be familiar with manufacturer’s instructions for over-the-counter oral healthcare products and be advised to use such products cautiously.

In this pilot study examining overdenture attachment retention, Locator attachments were tested in 4 different configurations: 6 implants, 4 implants (in 2 different configurations), and 2 implants. The 6-implant configuration exhibited the greatest retentive strength. The 4-implant configurations had strengths similar to each other, and both exhibited greater retention than the 2-implant arrangement.

Dental implant therapy can treat complete edentulism of the mandible predictably and successfully, but many patients cannot accept this approach due to medical or financial limitations. This case report describes advanced, traditional denture construction protocols that should be considered for these patients.

Four monolithic zirconium oxide materials (BruxZir Shaded 16 and BruxZir HT, Lava Plus, and inCoris TZI C) were compared to a lithium disilicate monolithic glass-ceramic material (IPS e.max CAD HT). Although the zirconium oxide materials were not as translucent as lithium disilicate at similar thicknesses, they were as translucent when compared at clinically recommended thicknesses. In addition, the flexural moduli and flexural strengths of the zirconia materials were significantly greater than those of lithium disilicate.

This clinicopathologic correlation presents the radiographic, clinical, and histopathologic findings, the differential diagnosis, and the treatment plan for a mixed-density lesion of the left posterior mandible of a middle-aged man. The lesion was deemed to be of bacteriologic origin, likely a polymicrobial infection containing actinomycetes.

Although cavities treated with an experimental adhesive system containing chitosan (0.2% and 0.5%) showed significantly fewer Streptococcus mutans and Lactobacillus casei than the negative control group, the concentrations of chitosan did not influence the antimicrobial effect; results were similar to those of a 2-step adhesive system.

When 4 composite resin materials were polished with various polishing systems and subjected to simulated toothbrushing cycles, surface roughness was affected by type of composite and polisher but not by toothbrushing time. However, surface roughness was affected by the interaction among composite, polisher, and toothbrushing time.

The results of shear testing and fracture analysis suggested that addition of a resin surface coating protected a resin-modified glass ionomer cement from moisture- and temperature-induced damage and increased shear bond strength.

An aggressive iatrogenic root perforation in a maxillary central incisor was managed surgically with mineral trioxide aggregate, which induced new bone formation and reestablished gingival and periodontal health, subsequently confirmed at follow-up examinations.

Palatoradicular grooves (PRGs) are morphologic defects that are predisposing factors for periodontal disease. This case report describes the successful use of calcium phosphosilicate graft material to manage advanced periodontal destruction associated with a PRG in the maxillary right lateral incisor.
