Cleidocranial dysplasia is a disease that occurs secondary to a dominant autosomal inheritance. There is no predilection for any genre or ethnic group. As there is a delay in the eruption and/or absence of permanent teeth, the patients usually report to a dental surgeon for replacement of the missing teeth. This condition is characterized by several cranial malformations and underdevelopment, absence of clavicles, and multiple impacted supernumerary and permanent teeth. The diagnosis of the condition is usually based on the presence of the above-mentioned main features and on clinical and familial evidence. Here we report a rare case of cleidocranial dysplasia in a male patient, having most of the characteristic features of this syndrome.

   Introduction Top

Cleidocranial dysplasia (CCD), also known as Marie and Sainton Disease, Scheuthauer Marie-Sainton Syndrome and Mutational dysostosis, is a rare disease that can occur either spontaneously or by a dominant autosomal inheritance, with no predilection of genre or ethnic group. [1] Cleidocranial dysplasia is a well-known, rare syndrome, usually caused by an autosomal dominant gene with high penetrance and a variable degree of expression. This condition is usually caused by a mutation of the core binding factor-α 1 gene, located at chromosome 6p21. However, 40% of the cases of CCD appear spontaneously, with no apparent genetic cause. The prevalence of CCD is 1/1,000,000, with higher rates in groups with a founder effect.

The main features of CCD are partial or complete absence of the clavicles, multiple supernumerary teeth, multiple impacted permanent teeth, retention of deciduous teeth, and delayed closure of the sagittal fontanelles. Reduced sutural maxillary growths can also occur. [2] Many CCD patients have the following triad of the features - multiple supernumerary teeth, partial or complete absence of the clavicles, and open sagittal sutures and fontanelles. Oral manifestations show a narrow and deep palate. The maxilla can be underdeveloped and shorter than normal. Another important finding is the crown and root anomalies in the supernumerary teeth, which are impacted and ectopic. [1]

Many approaches have been suggested for the treatment of such problems, including removal of the impacted permanent, supernumerary, and deciduous teeth, combined with insertion of an overdenture. Surgical removal of the deciduous and supernumerary teeth, combined with orthodontic traction of the impacted permanent teeth is another option.

   Case Report Top

A 30-year-old male patient came to the Department of Oral Medicine and Radiology. His chief complaint was missing teeth and he wanted a prosthesis. Upon general examination, he was of a short stature and his gait was normal [Figure 1].The patient had hypermobility of the shoulders [Figure 2]. On extraoral examination, it was found that he had frontal bossing, hypertelorism, and a wide nasal bridge. The midface was a little depressed because of an underdeveloped maxilla and the mandible appeared prognathic [Figure 3] and [Figure 4]. Intraoral examination revealed presence of the following teeth: 51, 52, 53, 55, 16, 17, 61, 62, 63, 64, 26, 27, 73, 74, 75, 36, 82, 83, 84, 85, and 46 [Figure 5].

On the basis of the clinical examination, the patient was diagnosed as having cleidocranial dysplasia, for which the differential diagnoses included hypohidrotic ectodermal dysplasia, focal dermal hypoplasia, Apert syndrome, and mandibulofacial dysplasia.

Furthermore, the orthopantomogram outlined the presence of 58 teeth in both the jaws. Out of these, 37 teeth were impacted and 21 were clinically present in the oral cavity [Figure 6]. The posteroanterior (PA) view of the skull showed an open anterior fontanelle and sutures of the skull [Figure 7]. A lateral view of the skull showed enlarged skull bones, along with multiple wormian bones [Figure 8]. The chest radiograph showed hypoplastic appearance of the clavicles [Figure 9].

According to the clinical and radiological findings, a diagnosis of cleidocranial dysplasia was given. The patient was referred to the Departments of Oral and Maxillofacial Surgery, and Prosthodontics, where extraction of the mobile teeth was planned, followed by insertion of a prosthesis.

   Discussion Top

Cleidocranial dysplasia is an autosomal dominant condition, characterized by generalized dysplasia of the bones and teeth. Owing to the defects in the clavicle and cranium, the term 'cleidocranial dysostosis' was coined by Marie and Sainton. [3]

Although there is a generalized involvement, the midline osseous structures are primarily involved. The prevalence of CCD has been estimated as one per million live births and the disorder is reported to be associated with a spontaneous mutation in the gene coding for osteoblast transcription factor RUNX2/Core binding factor and mapped to the chromosome 6p21. This factor is responsible for controlling the differentiation of the precursor cells into osteoblasts, which is essential for membranous as well as endochondral ossification. [4]

The clavicles are the first bones to ossify and/or are commonly affected, being either hypoplastic or aplastic. Complete absence of the clavicles occurs in about 10% of the cases and usually only the acromial end is absent. When there is a unilateral absence, it is usually the right clavicle. [4] In odontogenesis, RUNX2 regulates key epithelial mesenchymal interactions that control the progress of morphogenesis and histodifferentiation of the epithelial enamel organ. [5]

Cleidocranial dysplasia affects both males and females equally. The important clinical features include persistently open skull sutures, macrocephaly, brachycephaly, prominent forehead, hypertelorism, a depressed nasal bridge, midfacial hypoplasia, a narrow high-arched palate, delayed tooth eruption, enamel hypoplasia, a long neck, narrow sloping shoulders, a narrow thorax, absence of the clavicle, hands with finger length asymmetry due to extra epiphysis in metacarpals II and V, and multiple cone-shaped epiphyses, conductive deafness, scoliosis, a normal intelligence quotient, respiratory distress, growth retardation, recurrent sinus abnormalities, and occurrence of syringomyelia. [6] Our patient presented with most of these features, but lacked syringomyelia, asymmetric phalange length, scoliosis, and vertebral abnormalities.

Intraorally, the most striking feature of CCD is the presence of supernumerary teeth and impacted teeth, often located in the premolar area. Other dental abnormalities include incomplete and delayed eruption of the permanent teeth, as well as retention of the deciduous dentition. The causes of unerupted teeth are the disturbance of bone resorption, early loss of the gubernacular cord or canal, absence of cellular cementum, or lack of union between the dental follicle and the mucosa, due to interposed fibrous tissue, acting as a barrier to eruption. [7] The case reported had a total of 58 teeth in both the jaws, with 37 impacted teeth and 21 erupted teeth.

The skull shows typical characteristics, which include open metopic fontanelles and sutures, delayed suture closure, and multiple wormian bones. A frontal groove is seen in the midfrontal area, owing to this incomplete ossification. [8] The present case showed wormian bones and an open anterior fontanelle.

The differential diagnosis of this syndrome includes hypohidrotic ectodermal dysplasia, which includes hypohidrosis, anomalous dentition, onychodysplasia, and hypotrichosis; as also focal dermal hypoplasia characterized by relative focal absence of the dermis, skin atrophy, streaky pigmentation, multiple mucosal papillomas, and deformity of the extremities; Apert syndrome characterized by craniosynostosis, craniofacial abnormalities, and symmetrical syndactly of the hands and feet; pycnodysostosis mainly including a short-limbed stature, acro-osteolysis, osteosclerosis, and bone fragility; and craniofacial dysostosis, which is characterized mainly by premature craniosynostosis, with other abnormalities. [9],[10]

The treatment includes dental procedures to address the effects of the retention of deciduous dentition, presence of supernumerary teeth, non-eruption of the permanent dentition along with related malocclusion, and the periodontal conditions accompanying them. Maintenance of periodontal health is of prime concern in order to allow for an absolute and complete oral rehabilitation of the patient.

It was found that a diagnosis of the disorder should be made early so that the formation of supernumerary teeth can be diagnosed and early intervention undertaken. Sometimes, orthodontic extrusion of the impacted teeth is also required. Management of a patient with CCD is quite challenging. The earlier the treatment is initiated, the better is the prognosis. [4]

   Conclusion Top

In conclusion, despite the variable expressivity of CCD, early diagnosis through oral findings is possible. In addition to the oral features, diagnosis of this rare syndrome requires a reliable skeletal evaluation. This disorder not only causes physical discomfort to the patient, but also leads to psychological problems. Therefore, along with achieving a well-functional permanent dentition and an esthetically satisfying facial appearance, proper motivation and psychological support for the patients and their parents are also important.
