Rewaskularyzacja miazgi niedojrzałych zębów stałych z martwiczą miazgą i ze zmianami okołowierzchołkowymi – przypadki kliniczne
Few of the published studies used intracanal Ca(OH)2, rather than the triple antibiotic paste, although all of them achieved good results [3, 5, 15].
Bose et al. [3] observed that although the different medications produced apical closure and increased root length, a greater increase in dentinal wall thickness was observed with the triple antibiotic paste. With respect to the triple antibiotic paste, most authors advocate using equal proportions of ciprofloxacin, metronidazole, and minocycline, mixed with sterile water, since the flora in the root canal system is polymicrobial. A mixture of these three antibiotics has shown satisfactory results for disinfecting the canals and the healing of periapical lesions [8, 11, 13, 14].
The use of this paste is not without its complications, since it can lead to discoloration of the tooth crown, the development of bacterial resistance, and the appearance of allergic reactions [2, 11]. Moreover we should be aware that root resorption and active apical periodontitis lesion might occur when following these protocols [13-17]. In a comparative study concerning the components of the triple antibiotic paste, only minocycline caused tooth discoloration, so that it is recommended to restrict the use of this paste to the root canal and not to go beyond the cementoenamel junction [17]. In three of the cases presented, 1, 3, and 4, we were unable to evaluate discoloration since the molars had been fitted with metal crowns. In case 2, the [...]
