Hyaluronic acid for repairing interdental papilla in esthetic area: case report

ABSTRACT: Background: Hyaluronic acid is a treatment option for this deficiency gingival papilla, since it aims to increase tissue volume in the region of loss of interdental papilla, minimally invasive. Aim this study was to describe the application of Hyaluronic acid in a deficient gingival papilla. Case report: Patient presented absence of interdental papilla in the maxillary arch around upper anterior teeth. A comprehensive exam was performed, plus 2D photographs taken with a professional camera coupled to a device for image standardization, and an intraoral scanning with the OMNICAM scanner. Three applications of Hyaluronic acid were performed to fill the black spaces, at an interval of four weeks. The patient was followed-up for three months, and the recovery of papilla was observed. Conclusion: The Hyaluronic acid as gingival filling material can be considered as a treatment option for augmenting interdental papilla in aesthetic area.

Model for the evaluation of root wear by histometric analysis.

BACKGROUND: Knowledge of the wear to the root surface caused by different instruments is essential in the choice of the type of tool used in relation to the phase of periodontal treatment which the patient is undergoing. PURPOSE: The objective of this study was to present a new methodology for evaluating tooth wear produced by the instrumentation of the root surface. STUDY DESIGN: The present study used five teeth, the proximals of which were divided in three regions: coronal, median, and an apical. The coronal region was scaled with a curette, the apical region was irradiated with the Erbium, Chromium: Yttrium-Scandium-Gallium-Garnet laser (Er,Cr:YSGG laser) and the medial region was left untreated, which served as control. The teeth underwent a histological process and were analyzed histometrically. The t test (P < 0.05) was used to analyze the root wear. RESULTS: The regions that were irradiated with the Er,Cr:YSGG laser presented less wear (113.37 ± 32.94 µm) in comparison to the regions that were scaled with manual curettes (169.83 ± 24.76 µm) (P < 0.05). CONCLUSIONS: The methodology proposed was efficient in the measurement of the wear caused by the root instrumentation and proved easy to execute, easy to reproduce, and of low cost and with high calibration accuracy.
