Dental impaction defines a tooth that, instead of erupting to occupy its functional position, is partially or totally retained and remains within the bone. Retained teeth can be placed in the normal arch position through a combination of orthodontics and conventional surgical techniques, or a combination of orthodontics and laser surgery, as in the case here presented of a 14-year-old boy with an impacted first mandibular premolar, covered by bone, and with complete root formation and an erupted second premolar. The impacted premolar was surgically exposed using an Er,Cr:YSGG laser and at the same time an orthodontic bracket was bonded to provide traction to move the first premolar into its arch position.

A systematic assessment of the stability of SLA® vs. SLActive® implant surfaces over 12 weeks.
Evid Based Dent
January 2025
School of Medicine and Dentistry, University of Central Lancashire, Preston, UK.
Objective: This study aims to assess the impact of two implant surfaces, SLA and SLActive, on implant stability, measured by ISQ levels over a 12-week period.
Methods: A comprehensive search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Dentistry and Oral Sciences databases for randomized controlled trials (RCTs) up to February 2023 was conducted. The inclusion criteria were studies involving adult patients treated with SLA and SLActive implants, with assessment of implant stability through ISQ levels up to 12 weeks post-placement.

Human-driven changes in land cover and use can significantly impact species ants community structures, often leading to a decline in taxonomic diversity or species homogenization. Ant morphology, used as a proxy for ecological function, offers a valuable framework for understanding the effects of anthropogenic disturbances on ant diversity. This study explored the morphological diversity of ant assemblages in agricultural ecosystems and secondary forests in Italy and the Brazilian Amazon, analyzing how these communities are structured and adapted to different environments.
