Abstract

Dental anomalies are common in the permanent dentition when compared to the primary dentition, and more common in the maxillary arch. These could be localized to one or two teeth and could be generalized, affected by all teeth most of the times, which might be apart from syndromic or systemic disorders. The purpose of this report is to describe a unique case mandibular second permanent molar exhibiting oblique ridge and a buccal accessory cusp resembling the maxillary molar in a 13- year-old female.

Highlights

The dimension and morphology of teeth are noticeable aspects of any given phenotypic disparities. [1]
Dental anomalies are commonly seen in the permanent dentition than the deciduous dentition, whilst, very frequent in the maxillary arch than in the mandibular arch [3]
It is frequently difficult to differentiate whether the abnormality of a tooth is a true anomaly or an extreme variation in morphology of a tooth

Summary

Introduction

The dimension and morphology of teeth are noticeable aspects of any given phenotypic disparities. [1]. Dental anomalies are commonly seen in the permanent dentition than the deciduous dentition, whilst, very frequent in the maxillary arch than in the mandibular arch [3] These anomalies may be localized to one or two teeth or could be generalized, affected by all teeth most of the times [4,5]. It is frequently difficult to differentiate whether the abnormality of a tooth is a true anomaly or an extreme variation in morphology of a tooth These unusual formations of the teeth are very rarely noticed on regular examination [6]. Concrescence, cusp of carabelli, dens evaginatus, dilaceration, double tooth, prostyloid and talon cusp are frequently seen abnormalities of the teeth [2,7] The majority of these variations in shape affect the crown of the tooth [8]. As the variations in crown has not been reported in the literature, and the purpose of the present case report was to describe an unusual mandibular second molar with an oblique ridge and buccal cusp resembling the crown of the maxillary molar with cusp of Caraballi
