Risk indicators of operculitis.

BACKGROUND: The aim of this study was to illustrate the features of tooth number 38 and 48 having acute operculitis employing clinical parameters and radiological distinctiveness. METHODS: Fifty subjects of both genders in the age range of 19-36 years with a diagnosis of acute operculitis comprised the group for study. After thorough clinical examination, uniform orthopantomograms (Rotograph 230 eur, Villa Sistemi Medicali, Buccinasco, Milan, Italy) for each of the individual subject participating in the study was made. Four parameters were evaluated as plausible prognostic factors for the progression of acute operculitis. The χ2 test was used to foretell the role of individual factors studied in the progression of acute operculitis. Significance was set at P less than 0.05. For all statistical analysis, the SPSS (version 16; SPSS Inc., Chicago, IL, USA) software was used. RESULTS: Based on the assessment of the parameters investigated in this study, most likely to be among the essential determinants of acute pericoronitis are vertical angulations, part (50%) encapsulation, eruption point underneath the occlusal plane and existence of an encroaching opposing 28 and 18. CONCLUSIONS: Prophylactic extractions may thus be recommended in such cases, as a delay may result in grave complications. All patients with impacted wisdom teeth should be evaluated and the treatment planned must be based on their individual presentation.

Dens evaginatus and dens invaginatus in a double tooth: A rare case report.

The presence of dens invaginatus (DI) and dens evaginatus (DE) on same tooth is a rare phenomenon. However, when these dental anomalies occur on a double tooth, it becomes an extremely rare phenomenon. The authors report a rare case of DI and DE on fused permanent maxillary central incisor with supernumerary tooth in a 40-year-old male. The present article also focuses on the differentiating fusion from gemination and also reviews preventive and management strategies for tooth with complex dental anatomy.

Non-syndromic multiple talon cusps in siblings.

Talon's cusp is an anomalous structure that projects palatally from the cingulum areas of maxillary or mandibular anterior teeth. This dental anomaly may pose several pathological, functional and esthetic problems. Talon cusps usually affect a single tooth, but may rarely affect an entire sextant. Such multiple talon cusps may not always occur in association with a syndrome. Furthermore, they may exhibit a genetic pattern of inheritance. This article emphasizes rare occurrence of such nonsyndromic multiple talon cusps in two siblings.
