The porosity of resin-based composites was evaluated after incremental application of a hybrid material and sonicated application of a bulk-fill material in simulated box-type and cylindrical cavity preparations. Sonicated bulk-filled restorations in cylindrical cavities were the least porous, while restorations that were incrementally placed in cube-shaped cavities were the most porous.

When 10 patients with oral vascular lesions underwent cryotherapy or sclerotherapy, both procedures were clinically effective. Cryotherapy requires only 1 session, but the cost of the equipment is high. Sclerotherapy is widely accepted by patients, but more than 1 session is required.

An epithelial-myoepithelial carcinoma on the palate was treated surgically, and no recurrence or metastasis was observed 10 years postoperatively. A literature review found only 30 documented cases of epithelial-myoepithelial carcinoma associated with minor salivary glands.

A survey of 503 middle and high school athletes revealed that 56% of the respondents did not own a mouthguard. Among athletes who owned a mouthguard, the most commonly cited reasons for failure to wear it were forgetfulness and a lack of comfort. The dental profession should make a concerted effort to encourage enforcement of mouthguard usage policies among student-athletes.

In a prospective clinical study of 100 patients with temporomandibular disorder (TMD), the most common otologic manifestations were ear pruritus, otalgia, and aural fullness, showing a significant correlation with the female sex, severity of TMD, and frequency of TMD symptoms.

Different air particle abrasion protocols—with variations in particle types, duration of abrasion, and the distance between the device tip and the ceramic—were evaluated for their influence on the surface roughness of zirconia-based ceramic and the shear bond strength between the material and resin cement. Only the particle type was a statistically significant factor; air particle abrasion with silica-coated alumina resulted in higher shear bond strengths.

This study compared the antimicrobial efficacy of several irrigants against Enterococcus faecalis. BioPure MTAD was the most effective antimicrobial agent. While 0.2% chitosan did not show any inhibition zones, 1% chitosan was as effective as sodium hypochlorite, and both irrigants showed significantly greater effectivity than 2% chlorhexidine.

A 92-year-old man presented with asymptomatic, circumscribed, soft, flattened papules on his lower lip that were consistent with multifocal epithelial hyperplasia. Although it tends to occur in the first 2 decades of life, multifocal epithelial hyperplasia can be encountered in the elderly.

After a systematic literature review and meta-analysis, the Academy of General Dentistry presents clinical practice guidelines on the diagnosis and management of acid erosion. Basic Erosive Wear Examination is the recommended index for diagnosis of acid erosion in the dental practice setting. Recommended treatment options include stabilized stannous fluoride, stabilized stannous fluoride in combination with chitosan, prescription and over-the-counter concentrations of sodium fluoride, casein phosphopeptide–amorphous calcium phosphate paste, and 1.23% acidulated phosphate fluoride gel (alone or with laser treatment).
