Other interesting effects of alveolar corticotomies in orthodontics apart from the acceleration of tooth movement

The acceleration of orthodontic tooth movement due to alveolar corticotomies has been well documented in the literature. It is defined by a phenomenon of transient osteopenia named “the regional acceleratory phenomenon” by Frost. This biological mechanism has been described in studies on both humans and animals. However, other interesting effects in orthodontics are associated with alveolar corticotomies: higher amplitude of tooth movements, a decrease of the root resorptions and an increase of stability after orthodontic treatment

Au-delà de l’accélération du déplacement dentaire : autres effets des corticotomies alvéolaires d’intérêt en pratique orthodontique quotidienne

L’accélération du déplacement dentaire orthodontique par corticotomie alvéolaire est bien décrite dans la littérature. Elle se traduit par un phénomène d’ostéopénie transitoire, baptisé « phénomène d’accélération régionale » par Frost. Ce mécanisme biologique a été décrit via des études animales et humaines. Cependant, d’autres effets intéressants en pratique orthodontique sont associés aux corticotomies alvéolaires : augmentation de l’amplitude des mouvements dentaires, diminution des résorptions radiculaires et augmentation de stabilité post-traitement orthodontique

Orthodontics and oral mucosal lesions in children and teenagers

Children and teenagers with orthodontics may be affected by infectious, hereditary, traumatic, malignant, or idiopathic oral mucosa lesions. Orthodontists have to be able to detect, identify, and treat effectively or to address the patient to a specialist. Here we discuss this difference to make their diagnosis and management easier for the practitioner

Pratique orthodontique et pathologie de la muqueuse buccale chez l’enfant et l’adolescent

Les enfants et adolescents en cours de traitement orthodontique peuvent présenter des pathologies de la muqueuse orale d’origine infectieuse, héréditaire, maligne, traumatique ou idiopathique. L’orthodontiste doit pouvoir dépister ces lésions, les reconnaître, afin d’instaurer un traitement adapté et/ou d’adresser le patient à un spécialiste. L’objectif de cet article est de décrire ces différentes lésions pour un diagnostic et une prise en charge plus aisés

Molecular mapping of periodontal tissues using infrared microspectroscopy

<p>Abstract</p> <p>Background</p> <p>Chronic periodontitis is an inflammatory disease of the supporting structures of the teeth. Infrared microspectroscopy has the potential to simultaneously monitor multiple disease markers, including cellular infiltration and collagen catabolism, and hence differentiate diseased and healthy tissues. Therefore, our aim was to establish an infrared microspectroscopy methodology with which to analyze and interpret molecular maps defining pathogenic processes in periodontal tissues.</p> <p>Methods</p> <p>Specific key cellular and connective tissue components were identified by infrared microspectroscopy and using a chemical imaging method.</p> <p>Results</p> <p>Higher densities of DNA, total protein and lipid were revealed in epithelial tissue, compared to the lower percentage of these components in connective tissue. Collagen-specific tissue mapping by infrared microspectroscopy revealed much higher levels of collagen deposition in the connective tissues compared to that in the epithelium, as would be expected. Thus inflammatory events such as cellular infiltration and collagen deposition and catabolism can be identified by infrared microspectroscopy.</p> <p>Conclusion</p> <p>These results suggest that infrared microspectroscopy may represent a simple, reagent-free, multi-dimensional tool with which to examine periodontal disease etiology using entirely unprocessed tissue sections.</p
