Randomized Controlled Trial Comparative Study
A randomized clinical trial on the clinical and microbiological efficacy of a xanthan gel with chlorhexidine for subgingival use.
The main indication of the adjunctive use of local antimicrobials lies around situations in which the outcome of non-surgical mechanical treatment results in a limited number of residual pockets. The purpose of this investigation was to evaluate the clinical and microbiological effects of the subgingival application of a xanthan-based 1.5% chlorhexidine (CHX) gel (Xan-CHX), adjunctive to scaling and root planing (SRP) in localized periodontitis. ⋯ Adjunctive use of slow-released chlorhexidine might be considered in the management of periodontal disease and gingival inflammation to reduce the need for periodontal surgery.

Comparative Study
Reproducibility of three-dimensional cephalometric landmarks in cone-beam and low-dose computed tomography.
The purpose of this study is to compare the reproducibility of three-dimensional cephalometric landmarks on three-dimensional computed tomography (3D-CT) surface rendering using clinical protocols based on low-dose (35-mAs) spiral CT and cone-beam CT (I-CAT). The absorbed dose levels for radiosensitive organs in the maxillofacial region during exposure in both 3D-CT protocols were also assessed. ⋯ Cone-beam CT should be preferred over low-dose CT for developing three-dimensional bony cephalometric analyses.
