An unusual apical abscess

An unusual case is reported of an infected apical cyst attached to a vital tooth. The clinical and radiographic appearances were compatible with an apical cyst. Histology of the extracted tooth and attached cyst showed the tooth to be vital.     

Histomorphology of chronic apical periodontitis

Histologic mounts of 20 decalcified teeth were studied, the roots of the teeth after extraction preserved the connection with the periapical formation. Analysis of the received morphological data let make more exact the mechanism of forming and persisting the inflammation focus round dental root apex and give practical recommendations how to treat chronic apical periodontitis.     

One step pulp revascularization treatment of an immature permanent tooth with chronic apical abscess: a case report

Aim  To describe a case in which a mandibular right second premolar with a necrotic pulp, sinus tract, periradicular radiolucency and an immature apex underwent revascularization via a single treatment approach.
Summary  Revascularization procedures have the potential to heal a partially necrotic pulp, which can be beneficial for the continued root development of immature teeth. However, it is not clear which revascularization protocols are the most effective. This case report details the outcome of a successful revascularization procedure on tooth 45 (FDI) in a 12-year-old patient, eliminating the associated periapical pathosis within 19 months. The tooth was treated using coronal root irrigation with 6% NaOCl and 2% chlorhexidine without instrumentation in a single visit. The successful outcome of this case report suggests that this conservative revascularization treatment approach can preserve the vitality of the dental pulp stem cells and create a suitable environment for pulp regeneration, resulting in the completion of root maturation.   Key learning points

• • 

  The noninstrumentation procedure using 6% NaOCl and 2% chlorhexidine coronal irrigation may help preserve the remaining vital dental pulp stem cells believed to be critical for pulp revascularization.
• • 

  A single visit pulp revascularization protocol can be a favourable treatment option for an immature permanent tooth with a partially necrotic pulp.

     

Severe extrusion from an apical abscess: a case report

Penicillin as a supplement in resolving the localized acute apical abscess

ProblemAntibiotics are often prescribed indiscriminately to treat endodontic emergencies.ObjectivesThis study examined (1) the effect of penicillin supplementation on reduction of symptoms and (2) the course of recovery of localized acute apical abscess after emergency treatment.Study designsPatients with pulp necrosis and periapical pain and/or localized swelling were considered. Those eligible did not have any signs of spreading infections. Patients received appropriate local treatment, and a double-blind protocol was used to randomly assign them to one of three groups: penicillin VK group, placebo group, or neither medication group. All received ibuprofen 600 mg four times daily for 24 hours. Patients entered their pre- and postoperative pain and swelling experience on a visual analog scale for up to 72 hours.ResultsResolution was fairly rapid in most patients. Statistical analysis of the scores of 32 respondents revealed no significant differences (at p<0.05) between the three groups in course of recovery or symptoms at any time period.ConclusionsPatients with localized periapical pain or swelling generally recovered quickly with local treatment. The data did not show a demonstrable benefit from penicillin supplementation.
