Necrosis of intact premolar caused by an adjacent apical infection: a case report

Abstract

Although periapical inflammatory lesions are usually resulted by infection in the root canal system, this rare case showed that a periapical lesion related to an infected tooth may cause pulpal necrosis in adjacent intact tooth, with no history or clinical signs of caries, disease, trauma or developmental anomaly. This case also suggests that the periapical lesion can be treated conservatively, without surgical intervention. Furthermore, this case highlights the importance of prompt treatment of apical periodontitis before the lesion becomes extensive as well as follows up of large lesions.

Atypically grown large periradicular cyst affecting adjacent teeth and leading to confounding diagnosis of non‐endodontic pathology

“…Like the present one, the cases previously reported were diagnosed as periradicular cysts . The previous reports also showed clinical conditions suggestive of exacerbation with abscess formation , which was not observed in the present case.…”

“…Reports of teeth that became devitalised because of an inflammatory apical periodontitis lesion from an adjacent tooth are also scarce in the literature (14)(15)(16). Like the present one, the cases previously reported were diagnosed as periradicular cysts (15,16).…”

“…Although it is plausible that any expansive bone destructive process taking place in the periapical region of a vital tooth may exert pressure on the apical circulation, in the literature there are only a few reports of teeth that became devitalised as a consequence of an expanding inflammatory periapical lesion from an adjacent tooth (14)(15)(16). Moreover, information is limited to the histopathologic conditions of the pulp tissue of teeth associated with non-endodontic lesions.…”

Antibacterial activity of essential oil extracts from Curcuma xanthorrhiza roxb. rhizomes against bacteria causing pulp necrosis

“…1,2 Failure in root canal treatment is possibly due to the fact that those microorganisms are persistent and recolonize within the canal. 3 Root canal infection is a polymicrobial infection involving both gram-positive and gram-negative anaerobic bacteria. 4 The most common microorganisms found in root canal infections are Enterococcus faecalis and fusobacterium nucleatum, respectively as gram-positive and negative bacteria.…”

Bilateral dens evaginatus and associated cystic pathology: An unusual case report

“…15 The presence of vital teeth may also indicate pulp tissue that are infected incompletely or partially necrotic. 16 As a result, the diagnosis and treatment of DE-associated periapical lesions such as a periapical cyst may be overlooked or delayed, as there appears to be no apparent etiology for the radicular cyst such as a necrotic pulp due to caries.…”
