  • Title: Root surface biomodification using a dentin bonding conditioner.
    Author: Abitbol T, Settembrini L, Santi E, Scherer W.
    Journal: Periodontal Clin Investig; 1996; 18(2):27-30. PubMed ID: 9116468.
    Abstract:
    OBJECTIVE: The purpose of this investigation was to compare by scanning electron microscopy (SEM) the surfaces of roots treated with a dentin conditioning agent and other materials that have been used routinely in periodontal therapy for root surface demineralization, namely, citric acid and tetracycline hydrochloride. MATERIALS AND METHODS: Sixteen freshly extracted human teeth were randomly divided into four equal groups; each tooth was hand scaled and planed prior to root surface conditioning with citric acid, tetracycline hydrochloride, and a dentin bonding conditioner; Tenure Dentin Conditioner (DenMat Corporation, Santa Maria, CA). The last has been used previously in conjunction with a resin-ionomer barrier in cases involving guided tissue regeneration. Root specimens were prepared for scanning electron microscopy and representative micrographs were taken at 1000x and 2000x. RESULTS: The results of this study indicate that there are morphological similarities between surfaces obtained with the dentin conditioning agent and the other acidic materials that are used routinely in periodontal regenerative therapy. CONCLUSIONS: Root surface demineralization has been shown to remove the smear layer, and provides a surface which is conductive to mechanical adhesion and cellular mechanisms for growth and attachment.
