“…The enamel is hypocalcified and/or hypoplastic with a yellow or brown discolouration and can be soft on exploration with a dental probe [27]. Affected teeth are more susceptible to dental caries due to defective mineralisation [28, 29]. Radiographically, teeth with ROD have shortened roots with open apices [30].…”

Regional odontodysplasia (ROD) is uncommon developmental anomaly, which tends to be localised and involves the ectodermal and mesodermal tooth components. A five-year-old female was referred to Department of Child Dental Health at the Leeds Dental Institute regarding malformed primary teeth. On examination 64, 74, and 72 had localised hypomineralized enamel defect. The crown of 55 was broken down with only the root remaining below the gingival level. 54 has a yellowish brown discolouration with rough irregular surface. The upper anterior teeth show mild enamel opacity. Radiographically, 55 and 54 had thin radioopaque contour, showing poor distinction between the enamel and dentine and the classic feature of a wide pulp chamber. 15, 16, and 17 were developmentally delayed and were displaying the characteristic “ghost appearance.” Comprehensive dental care was done under local anaesthesia and it included extraction of the primary molars affected by ROD, stainless steel crown on 64, and caries prevention program. Fifteen months following the initial assessment the patient's oral condition remains stable and she is under regular follow-up at the department. Paediatric dentists should be aware of this anomaly as it involves both dentitions and usually requires multidisciplinary care.

“…Clinicaly is characterized by hypoplasia of enamel and dentine in teeth badly formed with size and form alteration; coloration varying of the yellow to chestnut; presence of smooth and extremely friable dentine which is due to structural defects and defective mineralization, which increases the possibility of the pulp to be easily displayed with tendency to develop abcesses. They can present mobility for having roots badly formed and its eruption does not occur or can be partial, presenting modification in the chronology of eruption [3,4,17,20,32,[34][35][36][37][38][39][40][41].…”

The regional odontodysplasia, also referred as odontogenic dysplasia, is a rare condition which has been described as an alteration of the dental development affecting the mineralized structures of both the permanent and deciduous teeth, and it has been associated with retardation in the eruption of the affected teeth, gum edema, hydrocephalus and Epidermal Nevus Syndrome. The etiology is still unknown, however, some hypotheses have been suggested about their origin. About its incidence, this disease is more frequent in the anterior segment of the maxilla and usually unilateral. Epidemiologically this disease shows no predilection for any racial group, being more frequent in the first and second decade of life and predominantly in females. Clinically the Odontodysplasia Regional is characterized as an hypoplasia of enamel and dentin in teeth badly formed with size alteration and form coloration varying of the yellow to chestnut; the presence of smooth and extremely friable dentine, tooth mobility and defective mineralization increases the possibilities of the pulp exposure and a tendency to develop abscesses. Radiographically has the appearance of ghosts tooth with a bizarre morphology; reduction of the normal radiopacity decrease of the thickness of the dentine and enamel structures. They generally present with open apexes; shortened or absent roots; diffuse calcification in the inside of the pulp. Histopathologically it presents with accented reduction of the amount of dentin, presence of great interglobular dentine areas and irregular standard of the dentine canals. Enamel is usually thin, hypoplasic and hypocalcified. The pulp presents atrophic areas, fibrose and hyalinization and the cement does not have marked structural alterations. The treatment of the Regional odontodysplasia has been the reason of many quarrels. This present essay aims to review the literature and report a clinical case.

Regional odontodysplasia: a review of the literature and report of four cases

Regional odontodysplasia (RO) is a rare dental anomaly involving both dentitions, mostly teeth of one quadrant. The characteristic findings are discolored soft teeth accompanied by gingivitis, swelling or abscess. Enamel and dentin are hypomineralised and hypoplastic, so that the 'ghost teeth' appear shadowy in radiographs with wide pulp chambers. The etiology is unknown. Epidemiological data is rare; 138 cases of RO have been published to date and reports on ultrastructure are few. An analysis of published cases of RO in the international literature is presented. The sex ratio of females to males was 1.7:1. The age at the time of diagnosis ranged between 4 and 23 years. The maxilla was more often affected (maxilla to mandible ratio 1.6:1). In 67 patients the deciduous and permanent dentitions were affected (47.1%). In 129 cases, affected teeth lay side by side. Missing tooth development was observed in 10.7%. Failure of tooth eruption of RO teeth occurred in 39.7%. In addition, four cases with RO which were collected over a period of more than 25 years are presented. Ultrastructural findings of one specimen are demonstrated.
