RÉSUMÉLes autotransplantations sont utilisées de préférence chez l'adolescent. Elles présentent un taux d'échec majoré dans les cas de dents matures chez l'adulte. L'absence de contraintes mécaniques et de traumatismes desmodontaux précoces est un facteur favorable à l'obtention d'une cicatrisation parodontale et endodontique pourrait être une solution appropriée pour améliorer la cicatrisation endo-parodontale. L'intérêt potentiel du calque pour évaluer la morphologie de la dent à remplacer et choisir le transplant le plus adapté semble évident. L'utilisation du calque est illustré au travers d'un cas de réinnervation d'une dent de sagesse mature transplantée chez un adulte.

Introduction: Direct tissue autofluorescence (AF) visualization devices such as VELscope® are gaining interest to improve early detection of oral potentially malignant disorders (OPMD) and cancers. The main objective of this study was to assess inter-observer reproducibility of incandescent light (IL) and AF observations for OPMD and cancer. Materials and methods: High risk patients (exposed to alcohol or tobacco) were screened by two independent operators with a conventional oral examination (IL) followed by AF examination. The primary endpoint was the inter-observer agreement on the decision to biopsy assessed by kappa coefficients.Accuracy of IL and AF were estimated by the relative true positive rate (RTPR, increase of sensitivity), relative false positive rate (RFPR, loss of specificity) and their ratio. Results: 179 patients were included. 833 lesions were identified after IL and AF. Indication for biopsy was retrieved for 41 patients (61 lesions). Inter-observer agreement on the indications for biopsy was 93.3% after IL (Kappa coefficient 0.88 [0.80, 0.97]) and 96.1% after IL and AF (Kappa coefficient 0.78 [0.66, 0.90]). RTPR was 1.2, RFPR was 1 and their ratio was 1.2. Conclusion: IL and AF examination has shown good inter-observer reproducibility. Adjunction of AF allowed diagnosing more leukoplakia without dysplasia.
