Prevention and interception of dysmorphoses in primary dentition by JJ VALLEE

In France, dental care still has difficulty defining the ideal age at which to manage a child. Yet, although for a long time the period of primary teeth before the age of 6 years was overlooked, today the results obtained, the parents’ expectations, and those of other medical specialists:

pédiatres, médecins, orthophonistes, ostéopathes… sont à l’origine d’une remise en question de beaucoup d’entre nous. Une prévention précoce dès 3 ans par un bilan permettra de guider la croissance par des conseils et un suivi régulier si aucun signe de dysmorphose n’est détecté. Dans le cas contraire, l’Interception permettra de stopper l’évolution de la dysmorphose dès son début, et ce, en traitant également la cause, dès la denture de lait. Ce sera une chance pour l’enfant.

How to explain eruption delays by J. GATIMEL, F. VAYSSE, M. ROTENBERG, E. NOIRRIT-ESCLASSAN
Tooth eruption is a genetically programmed phenomenon. Scientific progress has made it possible to identify molecular, cellular, and genetic players that orchestrate this complex mechanism. The dental follicle plays a key role in the intraosseous phase of eruption by regulating the bone remodeling that occurs in the vicinity of the dental germ.
An osseous resorption in the coronal part of the follicle creates an eruption pathway, and an osseous apposition then occurs at the level of its basal part. The follicle is therefore a polarized structure that controls the molecular and cellular mechanisms responsible for the movement of the tooth to its occlusal position.
Tooth eruption may present anomalies and, in particular, may be delayed. To
diagnose eruption delays and treat them as early as possible, questioning is essential during the clinical examination. Indeed, in many cases, a familial and genetic background is present. Recent scientific advances in molecular biology have made it possible to discover certain genes responsible for eruption anomalies and to develop new diagnostic tests as well as new therapies.
A better understanding of the eruption mechanisms has opened the door to
new perspectives in the management of eruption anomalies.

Enhance the quality of life of our adolescent patients by F. POURRAT
For a few years now, new instruments for measuring health status have been developed. One application of these new measurements is the assessment of their health status by patients themselves. This type of assessment is generally based on self-administered questionnaires.
In this context, quality of life is now among the criteria that health evaluation studies willingly include.

Early treatments by M.G. CHOUKROUN
The treatment period in the mixed dentition typically spans from 6 years to 10 years. The Bioprogressive philosophy has as its essential principle considering our patients not only from an anatomical standpoint, but also combining and adding the physiological and psychological aspects. It therefore seems interesting to learn what the psychological characteristics and implications of this age are.
For this introduction, we must recall a quote by Freud describing the different stages of the development of infantile sexuality. Curiously, he uses a dental criterion: “the Oedipus complex ends when the loss of the primary teeth is complete.”
Not being an odontologist, he could not refer to the permanent dentition; it is therefore the establishment of the mixed dentition. Freud thus dates very precisely the psychological stage that precedes our therapeutic period. As for the stage that corresponds to it, he calls it the “latency phase.”
