BACKGROUND: Leakage of components from endodontic materials (EM) can occur in case of apical extrusion into the periapical tissue. Therefore, an important prerequisite, besides the mechanical properties of the EM, is a high biocompatibility. In the present study, we elucidated the genotoxic potential of EMs of different base composition by utilizing the -H2AX assay. METHODS: For investigation of the genotoxic potential of EM, supernatants of commercially available EM were prepared and dilutions were applied to human gingival fibroblasts...

INTRODUCTION: Decreased sensitivity to occlusal load could lead to a greater risk of damage to endodontically treated teeth. Therefore, this study aims to test whether root canal treatment reduces the sensitivity of the treated teeth to occlusal load. METHODS: This is a comparative cross-sectional study of 124 patients who received root canal treatment. Treated teeth were compared with vital teeth on the contralateral side. After interviews with participants, their maximal bite forces (MBFs) of their root canal-treated and contralateral untreated teeth were measured using a digital bite fork force transducer...

INTRODUCTION: Regenerative endodontic procedures use bioactive molecules (BMs), which are active signaling molecules that initiate and maintain cell responses and interactions. When applied in a bolus form, they may undergo rapid diffusion and denaturation resulting in failure to induce the desired effects on target cells. METHODS: The controlled release of BMs from a biomaterial carrier is expected to enhance and accelerate functional tissue engineering during regenerative endodontic procedures...

Root canal treatment of immature teeth is considered a great challenge for both the dentist and the patient. The thinness of the root canals walls and the lack of an apical barrier leads to unpredictable treatment results. Revascularization is a novel promising treatment option in the field of regenerative endodontics for management of immature necrotic permanent teeth. This case presents a successful treatment of an 8-year-old patient with a partially necrotic, immature permanent mandibular right first molar pulp by revascularization...

This clinical report describes a relatively infrequent patient with inferior alveolar nerve damage caused by foreign material within the mandibular canal, which is one of the most severe complications of endodontic therapy. Although the circumstance is uncommon, it can have extremely unfavorable consequences for patients, such as anesthesia and paresthesia. In the present case, a patient suffered pain and severe paresthesia in the corresponding area after routine endodontic therapy. Several treatments were conducted to relieve the patient's symptoms, ranging from medication to tooth extraction, but all were of no avail...

INTRODUCTION: Dental caries is the most widespread chronic infectious disease. Inflammation in pulp tissues caused by dental caries will lead to periapical granulomas, bone erosion, loss of the tooth, and severe pain. Despite numerous efforts in recent studies to develop effective treatments for dental caries, the need for a potent therapy is still urgent. METHODS: In this study, we applied a gene-based therapy approach by administering recombinant adeno-associated virus (AAV)-mediated Atp6v0d2 (d2) RNA interference knockdown of d2 gene expression to prevent periapical bone loss and suppress periapical inflammation simultaneously...

This paper aims at exposing the foundations or reasons why, in cases of external tooth resorption, including those of orthodontic origin, one should not perform a root canal to treat it. That should be done only to teeth with contamination or pulp necrosis, to remove the periapical inflammation induced by microbial products. When facing cases of external tooth resorption, one's conduct must always respect the following sequence of steps: first of all, identifying the cause accurately; then, planning the therapeutic approach and, finally, adopting the conducts in a very well-founded way...
