Supernumerary eumorphic mandibular incisor in association with aggressive periodontitis

Dental Abnormalities and Oral Pathology of the Pataud 1 Upper Paleolithic Human

We have re-evaluated the dental abnormalities and oral pathology evident on the Mid-Upper Paleolithic Pataud 1 skeleton, including additional remains recently excavated for this individual, in an effort to expand current knowledge of Pleistocene human paleopathology, in light of current clinical and paleopathological assessments of oral variation and diseases. The young adult female Pataud 1 presents an impacted right M3, widespread periodontitis, large retromolar voids, double right maxillary supernumerary (paramolar) teeth, and new bone deposition on the medial mandibular rami and posterior maxillae. The Pataud 1 remains thus join a substantial sample of Pleistocene humans with congenital/developmental abnormalities, some of which (as in Pataud 1) consequently resulted in secondary abnormalities. M3impaction and supernumerary teeth are known in a couple of other Mid-Upper Paleolithic individuals, and mild to moderate periodontal disease appears to have been widespread. However, such marked resorption of the alveolar margin in a young adult is unusual, and the secondary inflammation (possibly septicemia) leading to new bone deposition is otherwise unknown in the sample and may have led to her death.

The doppelganger tooth: A diagnostic conundrum!

Abnormalities in tooth morphology and number are not uncommon. However, an exact clone of a normal tooth is a recondite clinical finding. Presence of supplementary teeth is mostly noticed in maxillary anterior, molar or premolar region, followed by mandibular premolar region in descending order of its site of occurrence. Supplemental tooth in mandibular anterior has a low prevalence of 0.01%. This paper reports one such rare case of nonsyndromic incisive jumeaux in mandibular anterior region during mixed dentition period.

Supplemental mandibular mesiodens: a diagnostic challenge

Developmental anomalies affecting the number of teeth are occasionally encountered clinically. The incidence of supernumerary teeth is approximately 1-3%. Among these are the maxillary anterior teeth, the maxillary molars, and the maxillo-mandubular premolars, in terms of descending order of occurrence. Supernumeraries occur rarely in the mandibular anterior teeth region. They may be either supplemental or rudimentary. We are reporting case of a supplemental type of supernumerary tooth in the mandibular anterior region and steps which were followed to distinguish supernumerary tooth from the normal series.

Association of mesiodentes and dens invaginatus in a child: a rare entity

Supernumerary teeth are defined as any teeth in excess of normal number. Mesiodens is a supernumerary tooth, in the central region of premaxilla between two central incisors. Dens invaginatus is a developmental anomaly resulting from invagination in the surface of tooth crown before calcification has occurred. Radiographically, it is observed as infolding of a radioopaque ribbon like structure, with equal density as enamel, extending from cingulum into a root canal and sometimes reaching the root apex. This paper aims to present a rare association of dens invaginatus with two mesiodentes in a child causing the eruption disturbance and unaesthetic appearance in anterior maxilla.

An unusual presentation of generalized aggressive periodontitis with multiple impacted supernumerary teeth

Aggressive periodontitis is a rare condition that progresses rapidly but affects only a small percentage of population. Most of the cases are familial. The presence of supernumerary teeth is also rather rare and often familial. Therefore, a concomitant presentation of aggressive periodontitis and supernumerary teeth in an individual has generated a great interest among clinicians. Here, we report a rare nonsyndromic case of generalized aggressive periodontitis with multiple impacted supernumerary teeth.
