Challenging Rousseau's map of Alopecia of Dental Origin
Objectives: The association of alopecia areata with infectious foci of dental origin is relatively common, attempts have long been made to map the distribution of the bald patch to causal teeth.
The aim of this study was to show the degree of concordance between the location of the alopecia and the causal tooth with the topographic map proposed by Rousseau-Descelle in 1939 and then by Lesclous in 1996.
Methods: The literature review was based on pubmed, using appropriate key words and criteria.
The causal tooth and location of the alopecia areata in each case report were documented.
Results: From the cases reported in the literature, the cause frequently corresponds to the wisdom teeth. For the same tooth, there was a diversity of locations, namely the parietal region, the parieto-occipital region, the labiomental region and the jugal region. Alopecia patches of dental origin are generally located on the same side as the infectious process, However, in some cases the bald patch was located on the contralateral side.
Conclusions: The results show that the proposed topographic map does not allow a correspondence between the causal tooth and the topography of the peladic alopecia and cannot be established as a reference for the identification of the causal tooth.
