OBJECTIVE To analyze the long-term effects of the Le Fort I osteotomy approach for the resection of juvenile nasopharyngeal angiofibroma (JNA) on maxillary growth and dental sensation. DESIGN Prospective collection of structured data. SETTING Tertiary care academic teaching hospital. PATIENTS Between 1993 and 1998, 5 adolescents (aged 10-14 years) constituted the evaluable cohort among 14...

Background: Enterococci are important gram-positive bacteria causing dental calculus in human beings; however, the role of these bacteria in oral cavity is unclear. The aim of this study was to investigate the presence of Enterococcal Surface Protein (esp) gene in Enterococcus faecalis isolated from dental calculus in the city of Sari, Iran. Materials and Methods: In the present study, 207 den...

Introduction. Data regarding methicillin-resistant Staphylococcus aureus, Legionella pneumophila, Hepatitis B virus suggest that the environment plays an important role in infection transmission in dental healthcare settings. The Centres for Disease Control and Prevention suggest covering clinical contact surfaces with disposal barriers or disinfecting them between patients. Both methods have d...

BACKGROUND A medium- and long-term perspective is required in human resource development to ensure that future needs and demands for oral healthcare are met by the most appropriate health professionals. This paper presents a case study of the Sultanate of Oman, one of the Gulf States with a current population of 3.8 million, which has initiated dental training through the creation of a dental c...

introduction based on previous researches, dental pulp stem cells (dpscs) are easily accessible with limited morbidity after collection. their embryonic origin, from neural crests, explains their multipotency. dpscs are primarily derived from the pulp tissues of the teeth.objective: this study was undertaken to isolate, culture, and characterize two different third molar and first premolar huma...

Learn the factors acting as determinants of relative dental and skeletal maturity findings. It is recommended that radiographs be made periodically including both during the mixed dentition (8-9 year old) and adolescence (12-14 year old) to evaluate growth and development, and to look for asymptomatic dental disease [1-3]. Substantial differences in the assessed biological and the known chronol...

Botulinum toxin (BTX) is a neurotoxin, and its injection in masticatory muscles induces muscle weakness and paralysis. This paralytic effect of BTX induces growth retardation of the maxillofacial bones, changes in dental eruption and occlusion state, and facial asymmetry. Using masticatory muscle paralysis and its effect via BTX, BTX can be used for the correction of malocclusion after orthogna...

Introduction Familiar or syndrome-associated hypo-, oligo or anodontia in children and adolescents demands for professional dental intervention, because poor dental function and aesthetics often result in psychosocial deprivation. Treatment challenges in these patients are to develop functionally and aesthetically acceptable intermediate solutions that strive for tooth and bone preservation and...
