Aim: The aim of this study was to compare the antimicrobial efficacy of Triple antibiotic paste (TAP), Calcium hydroxide and Acacia nilotica (A. nilotica) (Babbula) against Enterococcus faecalis (E. faecalis), Streptococcus mutans (S. mutans) and Candida albicans (C. albicans) as intracanal medicaments.
Materials and methods: The triple antibiotic paste mixture of (metronidazole, ciprofloxacin and minocycline), calcium hydroxide, Acacia nilotica (Babbula) were weighed and mixed with polyethylene glycol and agar well diffusion method was employed to study the antimicrobial efficiency against Enterococcus faecalis, Streptococcus mutans and Candida albicans
Results: All the intracanal medicaments showed zone of inhibition against Enterococcus faecalis, Streptococcus mutans and Candida albicans. Among all intracanal medicaments used in the study Triple antibiotic paste produced maximum zone of inhibition followed by Babbula and least by Calcium hydroxide.
Conclusions: Triple antibiotic paste showed the best antimicrobial efficacy followed by Babbula and least by Calcium hydroxide against Enterococcus faecalis, Streptococcus mutans and Candida albicans. More phytochemical studies need to be done. Further evaluation of concentrated extracts of Acacia nilotica (Babbula) could yield better results.
Internal resorption (IR), a rare phenomenon, is considered to be a catch-22 situation from the standpoints of both its diagnosis and treatment. It begins initially in the pulpal space and extends into the surrounding dentin. Its diagnosis and management have been a challenge to dental practitioners. Due to its insidious pathology, IR can progress to a great extent before its detection. It is usually asymptomatic and discovered by chance on routine radiographic examinations or by a classic clinical sign, "pink spot" in the crown. The treatment of this condition should be initiated as soon as possible to prevent further loss of hard tissue or an eventual root perforation. The resorption, if progressed to involve an external communication, has poor prognosis, and the tooth cannot be retained in most cases, and hence, extraction of the tooth is indicated. In modern dentistry, patients demand more than restoration of function; they are particular about the esthetics as well, especially in the anterior region. Once the proper diagnosis is made, the treatment modality should include steps taken to conserve the tooth structure as much as possible to restore tooth form, function, and esthetics. This case report describes the management of an IR of a maxillary central incisor that was treated nonsurgically with conventional root canal treatment followed by reinforcing the tooth with esthetic fiber post and conserving the natural tooth as such. A 9-month follow-up demonstrated clinically asymptomatic and adequately functional tooth, with radiographic signs of healing. In this case report, care was taken to conserve the tooth structure and avoid further weakening of the already compromised tooth. A tooth deemed having questionable prognosis was preserved intact and showed satisfactory healing with no progression of the resorptive defect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
