TL;DR: The aim of the present histologic study was to compare the in vivo and in vitro effects of an erbium: yttrium, aluminum, and garnet (Er:YAG) laser combined with a fluorescent calculus detection system, a diode laser (DL) and scaling and root planing (SRP) on periodontally diseased root surfaces.

TL;DR: An Er:YAG laser may represent a suitable alternative for non-surgical periodontal treatment and both groups showed a significant increase of cocci and non-motiles rods and a decrease in the amount of motile rods and spirochetes.

TL;DR: It was concluded that at 6 months following treatment both therapies led to significant improvements of the investigated clinical parameters, and ERL resulted in a statistically significant higher reduction of BOP than C.

TL;DR: There was a good interobserver reliability for the evaluation of patellar height according to the common radiological ratios, however, the high frequency of differing results between the different radiographic ratios showed that patella height classification as “alta,”“norma” or “baja” depends heavily on the chosen index.

TL;DR: The freeze-thawing procedure significantly affects chromatin structure and sperm morphology, especially in the head and the tail regions, and this may explain the lower fertilization rate and IVF/ICSI outcome when frozen-thawed spermatozoa are used.
