Prevention and interception of dysmorphoses in primary dentition by JJ VALLEE

Dental medicine, in France, still has difficulty defining the ideal age for managing a child. Yet, although the period of primary (baby) teeth before the age of 6 was long overlooked, today the results obtained, parents’ needs, 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 delayed tooth eruption by J. GATIMEL, F. VAYSSE, M. ROTENBERG, E. NOIRRIT-ESCLASSAN
Tooth eruption is genetically programmed. 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 intra-bony phase of eruption by regulating the bone remodeling that occurs near the tooth germ.
A bone resorption in the coronal part of the follicle creates an eruption pathway, and bone apposition occurs at its basal part. The follicle is therefore a polarized structure that controls the molecular and cellular mechanisms responsible for moving the tooth to its occlusal position.
Tooth eruption can present anomalies and, in particular, be delayed. To
diagnose delayed tooth eruption and treat it as early as possible, questioning during the clinical examination is essential. Indeed, in many cases there is a familial and genetic background. 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 mechanisms of eruption has opened the door to
new perspectives in the management of eruption anomalies.

Improve the quality of life of our adolescent patients by F. POURRAT
For the past few years, new measurement tools for health status have been developed. One application of these new measurements is evaluating 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 period of treatment in mixed dentition generally lasts from 6 to 10 years. The Bioprogressive philosophy is based on the essential principle of considering our patients not only from an anatomical perspective, but also by adding and incorporating the physiological and psychological aspects. It therefore seems interesting to discover what the characteristics and psychological implications of this age are.
For this introduction, we must recall a quote by Freud describing the different stages in 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 mixed dentition. Freud dates, very precisely, the psychological stage that precedes our therapeutic period. As for the one that corresponds to it, he calls it the “latency phase.”
