This study compared two different radiographic techniques for localization of impacted maxillary canines: vertical parallax (from a panoramic and a maxillary anterior occlusal radiograph) and magnification (from a single panoramic radiograph). The radiographs and the information regarding the impacted canines were obtained retrospectively from records of patients treated in the Day Stay Unit of...

The aim of the study was to determine whether there are differences in dental age (DA) using the method of Demirjian, in patients with impacted buccal or palatal maxillary canines in relation to unaffected controls. DA was estimated using Demirjian's method on panoramic radiographs of two groups of Caucasian patients. The study group consisted of 116 patients aged from 12 to 16 years (80 female...

AIM To investigate the morphologic parameters associated with cases of transmigrating mandibular canines. METHODS The orthodontic records of 3,500 patients were examined for the presence of transmigrating mandibular canines. Lateral cephalograms and study casts were analyzed for skeletal and dental parameters. Observations were made as to the sex and age of the subject, and side, location, an...

BACKGROUND Although many studies had been conducted on various aspects of canine visceral leishmaniasis (CVL) in domestic dogs in the endemic areas of Iran, investigations on CVL in wild canines are rare. METHODS This is a cross-sectional study was conducted from December 2012 to 2013 in northeast of Iran where human VL is endemic. Wild canines were trapped around the areas where human VL cas...

Animal models that simulate various aspects of human brain aging are an essential step in the development of interventions to manage cognitive dysfunction in the elderly. Over the past several years we have been studying cognition and neuropathology in the aged-canine (dog). Like humans, canines naturally accumulate deposits of beta-amyloid (Abeta) in the brain with age. Further, canines and hu...

Mucopolysaccharidoses (MPSs) are lysosomal storage diseases caused by a deficit in the enzymes needed for glycosaminoglycan (GAG) degradation. Enzyme replacement therapy with recombinant human alpha-L-iduronidase successfully reduces lysosomal storage in canines and humans with iduronidase-deficient MPS I, but therapy usually also induces antibodies specific for the recombinant enzyme that coul...

Pyometra, transmissible venereal tumor and dystocia had maximum prevalence out of various reproductive disorders in canines. Survival rate 62% of dystocia affected female canines following the treatment of dystocia is usually not satisfactory.

BACKGROUND AND AIMS An accurate color reproduction represents the final validation level of an esthetic anterior or posterior restoration. The aim of this study was to evaluate the color of permanent maxillary incisors, canines and molars, using a clinical spectrophotometer. METHODS The Vita Easyshade Advance 4.0(®) intraoral spectrophotometer was used by one clinician to determine the color ...

AIM To highlight anatomical variation in the mandibular canine. SUMMARY Two clinical case reports are presented to illustrate anatomical variation in the human mandibular canine. Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular can...
