This study presents a case of replacing two maxillary primary canines and related impacted permanent canines with two single implants, in conjunction with grafting lost hard tissue. By using immediate postextraction implant placement and provisionalization protocols, the stability of the implant was ensured while bypassing the bony void created by the removal of the primary canines. In this res...

OBJECTIVES To assess the diagnostic value of panoramic views (2D) of patients with impacted maxillary canines by a group of trained orthodontists and oral surgeons, and to quantify the subjective need and reasons for further three-dimensional (3D) imaging. MATERIALS AND METHODS The study comprises 60 patients with panoramic radiographs (2D) and cone beam computed tomography (CBCT) scans (3D),...

OBJECTIVE The aim of the study was to evaluate patients treated for impacted mandibular canines through a combined surgical and orthodontic approach. STUDY DESIGN The cases which were made button operations of impacted mandibular canines were selected from 5100 panoramic radiographs taken from patients who made use of our oral and maxillofacial surgery services between January 1998 to April 2...

BACKGROUND AND AIMS The aim of this study was to determine whether variations in the mesiodistal dimensions of mandibular canines had any role in sex determination. MATERIALS AND METHODS The study comprised of patients in the 19‒24-year age group (20 males and 20 females). Mesiodistal dimensions of mandibular canines was measured at the maximum mesiodistal width, first intraorally, then on pl...

Human mandibular canines do not present an internal anatomy as simple as could be expected; there are such canines with a single root and two canals, two roots or fused roots. The existence of mandibular canines with more than one root canal is a fact that clinicians ought to keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with...

This clinical article reports a technique, apicotomy, for managing dilacerated or ankylosed canines. The records of 3 patients successfully treated with apicotomy are presented. Orthodontists observe clinically significant incidences of impacted maxillary canines in their daily practices. Several procedures have been described to bring an ankylosed, impacted tooth into occlusion. Luxation is th...

BACKGROUND The angiotensin II type 1 receptor (AT1R) plays a key role in regulating cardiorenal function. Classic "unbiased" AT1R antagonists block receptor coupling to both G(αq) and ß-arrestin-mediated signals, which desensitize G-protein signaling as well as transduce G-protein-independent signals. TRV120027 is a novel ß-arrestin-biased AT1R ligand, which engages ß-arrestins while blocking G...

Lagochilascariasis is a parasitic disease caused by a helminth of the order Ascaroidea, genus Lagochilascaris that comprises 6 species, among which only Lagochilascaris minor Leiper, 1909, is implicated in the human form of the disease. It is remarkable that the majority of cases of human lagochilascariasis in the Americas have been reported in Brazil. The natural definitive hosts of this paras...

We detected Leishmania mexicana in skin biopsies taken from a stray canine (Canis familiaris) and Texas mouse (Peromyscus attwateri) at two ecologically disparate sites in west and central Texas using polymerase chain reaction (PCR). A single PCR-positive dog was identified from a sample of 96 stray canines and was collected in a peri-urban area in El Paso County, Texas. The PCR-positive P. att...

Upper canines in microchiropteran bats show a variety of cross-sectional shapes. A consistent feature of all species studied here is that the tooth is edged and not simply round or oval. Prominent sharp edges are positioned in several directions but particularly antero-medially toward the incisors and posteriorly toward the premolars. These edges appear to direct the cracks made in food items t...
