Contemporary Microbial and Antimicrobial Considerations in Regenerative Endodontic Therapy.

INTRODUCTION

Regenerative endodontic therapy (RET) has gained considerable attention and wide approval. Although it is being performed routinely, the outcomes remain unpredictable, and the optimal approaches for treatment are not established. It has been shown that bacterial persistence in root canals in these cases significantly interferes with healing and root maturation. However, few objective clinical studies have evaluated the complex microflora present in the infections or the efficacy of various clinical procedures. In addition, the extent of the infection and biofilm maturation in immature teeth with necrotic pulp has been understudied. Furthermore, most models used in preclinical evaluation of these issues do not fully elucidate the complexity or variability of the clinical situation.

RESULTS AND CONCLUSION

In this review, the main biological and clinical problems pertaining to RET will be discussed. Contemporary analysis of complex microbial communities will be reviewed with emphasis on how these types of analyses can provide clinically useful data. In addition, current and proposed approaches for the effective disinfection of the root canal environment without interference with stem cell viability or integrity of the dentin matrix in these cases will be explored. The future of research in this field, including better and more customizable approaches in RET, in light of recent technological advances and progress in endodontics, will be outlined.
