A Comparison of Three Camera Systems for Intraoral Photography.

A single lens reflex camera, a prosumer camera and a smartphone camera were compared for their ability to produce digital intraoral images. Standardized intraoral images produced by the three cameras were evaluated according to sharpness, depth of field, exposure, white balance and image composition. The digital SLR camera was significantly superior to the prosumer camera regarding sharpness and depth of field.

Scaling and root planing vs. conservative surgery in the treatment of chronic periodontitis.

A renewed interest in conservative surgical techniques has been fueled by new technology, changes in referral patterns to periodontists and a desire to achieve periodontal health in the least invasive, most cost-efficient manner possible. Trends suggest that an increasing amount of periodontal care is being provided in the offices of general dentists. If true, it is likely that patients receiving care in these offices will be offered simpler surgical treatment modalities that do not require an extensive armamentarium.

Crown lengthening in the maxillary anterior region: a 6-month prospective clinical study.

The purpose of this study was to assess osseous parameters and stability of maxillary anterior teeth following crown lengthening surgery. Thirty-six patients requiring facial crown lengthening of 277 maxillary anterior and first premolar teeth were included. Presurgical and intraoperative clinical measurements were recorded at baseline and 1, 3, and 6 months postsurgery at midfacial, mesiofacial, and distofacial line angles.
