A new method for deep caries treatment in primary teeth using ozone: a retrospective study

Abstract

AIM: The aim of this study was to assess the effectiveness of a new protocol for deep caries treatment in deciduous teeth based on: 1) the incomplete removal of carious dentin tissue; 2) the use of new technology (ozone) for the disinfection of carious dentine; 3) the creation of a peripheral seal in healthy tissue for bonding procedures with rubber dam isolation. MATERIALS AND METHODS: From a personal database, authors selected 50 consecutive patients (28 males, 22 females; mean age 5.8 ± 1.7 years) in whom this new protocol was applied on posterior deciduous molars, for a total of 94 restorations. CONCLUSION: The deciduous teeth considered for this study, if treated conventionally, would have probably been subjected to pulpotomy, because of the extension of the carious lesions. The proposed protocol, through the use of ozone, proved to be an excellent alternative, with the fundamental advantage of saving dental tissue and preventing the invasion of the pulp chamber.
