Context: Regional odontodysplasia (R O) is an uncommon developmental anomaly affecting a localized area of dentition, with distinctive clinical and radiographic findings. This article reviews a case of 10-year-old female who reported with RO in partially erupted mandibular anterior teeth. Aims: To highlight the likelihood of occurrence of Bilateral Mandibular Regional Odontodysplasia as a rare developmental anomaly. It commonly affects a localized area of dentition. Settings and Design: The representative tissue received was 10% formalin fixed hard tissue measuring about 1x0.5 cm in diameter. Materials and Methods: Ground section was done for surgically removed teeth and observed under optical microscope. Conclusions: In the ground section, the enamel and dentin were of variable thickness producing an irregular surface with central enlarged pulp cavity. Interglobular dentin and globular masses interrupting the dentinal tubules were also seen. All the …show more content…
This overall appearance gives a faint radiolucent image hence commonly termed as "Ghost teeth". The other terminologies for RO are Odontogenic dysplasia, Localized arrest tooth development, Unilateral dental malformation, Odontogenesis imperfect and Familial amelodentinal dysplasia.2 The etiology of RO remains unclear however numerous factors like local trauma, teratogenic drugs, Rh incompatability, neural damage, nutritional and vitamin defeciency etc have been considered. The maxilla is affected twice as often as the mandible. It is usually unilateral but rarely bilateral & rarely crosses the midline. Females are affected more often than males (1.4:1).3 This is an interesting case reportof bilateral mandibular involvement, a feature that is rarely reported in
