Histologic Characterization of Engineered Tissues in the Canal Space of Closed-apex Teeth with Apical Periodontitis

Introduction: The aim of this study was to investigate the capacity of endodontic regenerative procedures combining an induced blood clot, platelet-rich plasma (PRP), and bone marrow aspirate (BMA) to regenerate dental pulp in canine closed-apex necrotic teeth. Methods: Apical periodontitis was induced in 20 upper and lower premolars of 2 dogs. After biomechanical preparation, enlargement to a #60 file, and disinfection with a triantibiotic paste for 28 days, the roots were randomly assigned to 4 treatment groups: blood clot (BC), BC + PRP gel, BC + BMA gel, and BC + BMA/PRP gel. Negative controls were also included. After a 3-month follow-up period, the animals were killed. Results: Histologic analysis showed the presence of newly formed vital tissues (connective, cement-like, and bone-like tissue) in 23 of the 32 treated roots (71.87%). There was no statistically significant difference between the treatment groups. Conclusions: New vital tissues were formed and characterized as connective, cementum-like, or bone-like, but not as pulp-like tissue; PRP and/or BMA did not improve the tissue ingrowth. © 2013 American Association of Endodontists.

Glaucoma secundário em cães e gatos

Glaucoma is a syndrome that affects animals of different species and in different moments of his life, having variables causes in function of this presentation. It is an ophthalmic emergency that may develop irreversible vision damage as well as the patient's aesthetic presentation. Increased intraocular pressure, presence of engorged episcleral vessels, conjunctival hyperemia, pain, anterior uveitis, lens luxation and buftalmia are commonly clinical signs presented by dogs while in cats, signs are less expressive, noting mydriasis, mild ciliary injection and progressive buftalmia. For diagnosis are carried out three basic procedures: tonometry, gonioscopy and ophthalmoscopy. The treatment can establish with medical therapy with or without surgical intervention, however, at some point it will be necessary to perform enucleation or evisceration of the eye bulb.
