Dentoskeletal effects of molar distalization with miniscrew-anchored cantilever and pendulum appliance for Class II correction.

Introduction: The objective of this study was to compare the dental and skeletal changes promoted by the miniscrew-anchored cantilever and pendulum appliance for Class II correction.

Methods: This retrospective study involved 52 patients with Class II malocclusion divided into 2 groups according to the treatment received: the miniscrew group (MG) with 23 patients (14 females and 9 males; mean initial age of 12.42 years) treated using the miniscrew-anchored cantilever, and the pendulum group (PG) with 29 patients (21 females and 8 males; mean initial age of 13.

Bioactive-based spray and spot-on formulations: Development, characterization and in vitro efficacy against fleas and ticks.

The flea Ctenocephalides felis felis and the tick Rhipicephalus sanguineus are ectoparasites of great importance in veterinary medicine that can affect pets, also impacting the lives of owners due to the possible transmission of zoonoses. Due to the negative impact on animals, owners and the environment, synthetic chemicals are being replaced by natural alternatives. Eugenol and carvacrol stand out as bioactive substances with potential antiparasitic activity.
