Myofibroma is a rare benign localized or generalized proliferation of myofibroblastic tissue occurring mostly in infants or children. In the oral region, most lesions occur in the mandible, lip, buccal mucosa, and tongue; however, the lesions arising in the maxilla are very rare. Myofibroma has an aggressive clinical presentation and is often treated aggressively because of an inappropriate diagnosis. A unique feature of central myofibroma of the jaws is the potential for teeth and other odontogenic structures to be involved by tumor...

This article describes the forces of the muscles from the stomatonathic system and how they interact in many children to change the normal forces of growth. Because of this change in muscle forces there is a change from normal teeth and bone growth positions to abnormal positions. These normal and/or abnormal changes in muscle forces are the basis for development into class one, class two and class three occlusions. This is very valuable information for the orthodontic clinician because these muscle forces are the fundamental basis for all orthodontic treatment...

The oromandibular-limb hypogenesis syndrome comprises a group of anomalies which simultaneously affect the mandible, tongue, and maxilla with or without reductive limb anomalies. It is characterized by failure of development of the intraoral region and distal extremities. Multiple and variable deformities of the mandible, maxilla and tongue may occur in combination with a variety of limb defects. The wide range of presentation and combination of anomalies make classification difficult. They usually feature primarily in sporadic case reports because of their low incidence...

The clinical impression procedures described in this article provide a method of recording the morphology of the intaglio and cameo surfaces of complete denture bases and also identify muscular and phonetic locations for the prosthetic teeth. When the CAD/CAM technology for fabricating complete dentures becomes commercially available, it will be possible to scan the denture base morphology and tooth positions recorded with this technique and import those data into a virtual tooth arrangement program where teeth can be articulated and then export the data to a milling device for the fabrication of the complete dentures...

BACKGROUND: Primary failure of tooth eruption (PFE) is a rare condition affecting any or all posterior quadrants. Unilateral involvement of maxillary and mandibular quadrants causes a dramatic posterior open bite that requires complex management strategies. CASE REPORT: An 8 year-old boy attended the Dublin Dental School and Hospital regarding infra-occlusion of his right maxillary and mandibular primary molars. Both right first permanent molars had also failed to erupt...

AIM: This clinical report discusses the importance and use of third molars in the adult patient by presenting a case in which their use during orthodontic treatment allowed occlusal improvement. SUBJECT AND TREATMENT PLAN: The patient was a Japanese adolescent boy who had a skeletal Class III malocclusion with severe lateral deviation of the mandible, significant loss of posterior occlusal vertical dimension, due to premature loss of the maxillary and mandibular left first molars, and furthermore, both first molars had advanced carious lesions that had resulted in reduced crown heights and bilateral chewing surfaces...

The insulin-like growth factors (IGF) are a family of growth factors, receptors and binding proteins that are involved in numerous growth and differentiation processes, as well as in various pathological conditions. The aim of this review is to summarize data that has been accumulating in recent years linking the IGF system to a number of physiological and pathological oral processes. The IGF system fulfills an important role in growth and development of teeth, mandible, maxillae, and tongue. It has been postulated that IGF-I may be of great value in the treatment of periodontal defects and in tissue healing...

Acid demineralization of teeth causes occlusal erosion and attrition and associated non-carious cervical lesions at sites relatively unprotected by saliva. Associations of occlusal pathology and cervical lesions were looked for in 450 patients with toothwear, and 174 subjects with cervical lesions were identified. Associations of occlusal attrition, or erosion, or no wear, with cervical lesions at 72 buccal and lingual sites were recorded from epoxy resin replicas of the subjects' dentitions (3241 teeth). Criteria used to discriminate occlusal erosion from attrition; and shallow from grooved and wedge-shaped cervical lesions were delineated by scanning electron microscopy (SEM)...

The representation of the oral structures in area 2 of the postcentral somatosensory cortex was studied in conscious macaque monkeys by recording single-neuron activities. A total of 58 penetrations were made in the oral region of five hemispheres in three animals and 707 neurons were isolated. The receptive field characteristics were identified for 480 neurons. Among them, 62 neurons along 21 penetrations responded to mechanical tooth stimulation (periodontal mechanoreceptive neurons). The overwhelming majority (81%, 50/62) of periodontal mechanoreceptive neurons had receptive fields on several teeth in either jaw...

Cell migration and adhesion during embryonic development are complex processes which likely involve interactions among cell-surface carbohydrates. While considerable work has implicated proteoglycans in a wide range of developmental events, only limited attention has been directed towards understanding the 7role(s) played by the related class of mucin-type O-glycans. The initial step of mammalian mucin-type O-glycosylation is catalyzed by a family of UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferases (ppGaNTases)...

The rate at which substances diffuse from dental plaque influences the rate of clearance of acid and bacterial toxins from plaque into saliva. The aim of this study was to compare the rates of clearance of potassium chloride, as a model substance, from artificial plaque of 3-, 4-, and 6-mm-diameter, positioned bilaterally at different locations in the mouth. The diffusant was KCl (1 mol/L) in a 1.0% agarose matrix, placed in wells 1.5 mm deep, in small acrylic devices 3 mm thick, which could be fastened to the teeth with dental floss and removed after different time periods...

The position of the resting tongue has been reportedly classified as normal or abnormal. The problems introduced by the abnormal tongue position relating to denture retention and stability have been sufficiently underlined. In the present study, the bibliography on the abnormal tongue position and its effect on denture function was reviewed. Additionally, the criteria for characterizing the tongue position as well the causes of the abnormalities, as reported in the literature, were discussed. Finally, a pilot epidemiological study was conducted, with the purpose to determine the incidence of the abnormal tongue position among edentulous patients as opposed to the dentate...

Two female patients, aged 14 years 5 months and 17 years 3 months with skeletal Class III open bite and temporomandibular dysfunction are presented. They had previously been classified as orthognathic surgical cases, involving first premolar removal. The primary treatment objective was to eliminate those skeletal and neuromuscular factors that were dominant in establishing their malocclusions. These included abnormal behavior of the tongue with short labial and lingual frenula, bilateral imbalance of chewing muscles, a partially blocked nasopharyngeal airway causing extrusion of the molars, with rotation of the mandible and narrowing of the maxillary arch...
