ABSTRACT

Apical periodontitis is an inflammation and destruction of the periradicular tissues due to various insults to the pulp in the form of infection, trauma, and faulty dental procedures. Conditions regarding this are treated employing root canal therapy. Recent innovations show that copper calcium hydroxide nanoparticles and their electrophoresis can be used to treat apical periodontitis effectively. To evaluate the effectiveness of copper calcium hydroxide nanoparticles in the treatment of apical periodontitis, a literature search was done using PubMed, Cochrane Central Register of controlled Trials (CENTRAL), Science Direct, and Lilacs using the MeSH (Medical Subject Heading) terms Copper calcium hydroxide, apical periodontitis, nanoparticles, and electrophoresis. Of a total of 167 articles screened, 44 were full-text articles assessed for eligibility and four articles were taken for the qualitative analysis. This review was recorded according to the PRISMA GUIDELINES. Four randomized controlled trials were included in the review process. The copper calcium hydroxide particles were compared with other root canal medicament materials. It was found that copper calcium hydroxide and its electrophoresis were used in the treatment of apical periodontitis and were found to be one of the effective methods. Copper calcium hydroxide nanoparticles were effective against the destruction of the periradicular tissues.

ABSTRACT

Endodontic failure has been and continues to be a problem for endodontics-specialists. Complicated anatomy, numerous foramens, and accessory canals are an environment for microorganisms to infect the teeth. The purpose of the present work was to evaluate the regeneration of copper-calcium hydroxide (Cupral)-endodontically treated teeth diagnosed with apical periodontitis using an electrophoresis technique. In total, 132 patients, aging from 19 to 65 years old, underwent endodontic treatment mono- and multi-radicular teeth, with complicated canals from January 2019 to June 2020. The patients were divided into two groups: (i) the control group-which included 54 patients (n = 62 teeth) receiving endodontic paste (Calcipast + 1) and, as final filling, the AH-PlusTM cement-and (ii) the Cupral group, which included 78 patients (n = 80 teeth) receiving Cupral paste plus the electrophoretic current and, as final filling, the Atacamit-alkaline cement. The clinical cases were periodically observed along an 18-month follow-up period via radiography. Data were expressed as focal size of the lesions (mean ± standard error (SEM) of all the radiographic outcomes) observed in each group at each interval point. Statistical analysis was performed using the Student's t-test that allowed us to compare the control and Cupral groups; the statistical significance was set at p < 0.05 and p < 0.01, where the latter was highly significant. Before treatments, the focal sizes were 4.8 mm and 4.95 mm for control and Cupral-treated groups, respectively. After 6 months, the mean focal sizes were 3.9 mm and 2.14 mm for the control and Cupral groups, respectively. After 12 months, in the control group, the mean focal size was measured at 2.8 mm, while, in Cupral group, the lesion size decreased down to 0.31 mm and a highly dynamic regeneration of the destructive focal-bone occurred. After 18 months, the lesions were further significantly reduced in the control group (mean values of 2.62 mm), while they were barely detectable in the Cupral group (0.2 mm). In conclusion, we provide initial evidence that the Cupral-electrophoresis methodology is effective in treating destructive periodontitis of teeth with problematic canals up to 18 months, thus allowing teeth preservation.
