Growth hormone (GH) secretion affects bone and cartilage physiology. This study investigated the effect of GH on the size of the craniofacial structures and their angular relationship. Three different models of mice with a genetically altered GH axis were used: GH excess (giant), dwarf GH antagonist (dwarf-Ant), and dwarf GH receptor knockout (dwarf-KO) mice. Each model was compared with the co...

Anterior crossbite is the term used to describe an abnormal labiolingual relationship between one or more maxillary and mandibular incisor teeth. Different techniques have been used to correct anterior crossbite. This paper describes the use of bonded resin-composite slopes for the management of anterior crossbite in children in early mixed dentition.In each of the cases presented here, dental ...

AIM To present the 14 year follow-up of a case in which an avulsed permanent maxillary central incisor was replaced by autotransplantation of a mandibular premolar. SUMMARY A mandibular premolar (Moorrees' stage 3) was transplanted into the space left by an avulsed permanent maxillary central incisor after a delay of 3 months. Recall examination 14 years after transplantation revealed a norma...

Tooth regeneration by cell delivery encounters translational hurdles. We hypothesized that anatomically correct teeth can regenerate in scaffolds without cell transplantation. Novel, anatomically shaped human molar scaffolds and rat incisor scaffolds were fabricated by 3D bioprinting from a hybrid of poly-epsilon-caprolactone and hydroxyapatite with 200-microm-diameter interconnecting microchan...

Anatomy: Camelids have dentition designed for grinding of forages similar to other herbivores. They have incomplete rostral arcades with three lower incisors but only one upper incisor per side. The premolars and molars are referred to as the cheek teeth and are well established. The rostral and caudal roots of the cheek teeth do not communicate in llamas and alpacas. Disease can be confined to...

OBJECTIVE To evaluate the degree of perception of laypersons, dental professionals, and dental students regarding dental esthetics in cases with mandibular central incisor extraction. MATERIALS AND METHODS Using a smile photograph of a person with normal occlusion and all teeth, modifications were made to reflect the extraction of a mandibular incisor of various compositions and sizes. For th...

Teflon membranes were interposed between soft tissue flaps and roots in 4 human suprabony lesions affecting the mandibular incisor teeth in 1 volunteer patient. 4 suprabony lesions affecting the mandibular incisor teeth were used as comparisons in a 2nd patient. All roots were debrided using ultrasonic and manual instruments and the most apical positioned calculus/site on the facial surface was...

A 66-year-old man visited our department with the chief complaint of poor esthetics due to loss of a fixed partial denture in a maxillary incisor tooth and difficulty in mastication due to an ill-fitting, mandibular removable partial denture. An analysis of the occlusal vertical dimension resulted in a diagnosis of infraocclusion. After increasing vertical dimension with a provisional restorati...

The most common clinical sign of equine dental disease is quidding (dropping partially masticated food) due to oral pain from sharp dental overgrowths, which can also cause bitting problems and occasionally head shaking. Weight loss is not a common sign unless dental disease is severe and chronic. With apical infections of the cheek teeth, mandibular swellings and fistulas; or alternatively in ...

OBJECTIVE The aim of this study was to verify, in vivo and in vitro, the prevalence of root canal bifurcation in mandibular incisors by digital radiography. MATERIAL AND METHODS Four hundred teeth were analyzed for the in vivo study. Digital radiographs were taken in an orthoradial direction from the mandibular incisor and canine regions. The digital radiographs of the canine region allowed v...
