“…There is no consensus regarding the clinical and radiographic findings present in patients with dentin dysplasia type I [6]. In this case, the changes observed are not characteristic of any DD I subtype described [6,9,10]. Dysplasia dentin type I has been reported in the literature as a hereditary disease of autosomal dominant character.…”

This paper aims to report the case of a child with dentin dysplasia type I. An 8 year old female child was referred to the Children's Dental Clinic of the Universidade Federal do Piauí with an aesthetic complaint caused by missing teeth. Four permanent first molars, premolar upper right and upper left permanent canine were present. There was satisfactory oral hygiene and no dental diseases. Anamnesis and laboratory tests did not detect any systemic disorders. Evaluations of initial panoramic radiographs and computed tomography showed permanent teeth with apparently normal crowns, with short and conical roots and obliteration of the pulp chamber, confirming the diagnostic hypothesis of Dentin Dysplasia type I. Root Dentin Dysplasia or Dentin Dysplasia type I is a rare hereditary autosomal dominant disorder, with a complex diagnosis, and the need for evaluation and interdisciplinary planning. There is no specific treatment for this genetic condition. Temporary mucosa-supported prosthesis reimbursed with resilient resin was made to preserve the sites of erupted teeth and those erupting. Monitoring is to be done until the growth of the facial structures is completed, allowing for rehabilitation with fixed prostheses on implants.

“…Дисплазію дентину І типу вважають спадковою хворобою, що передається аутосомнодомінатним шляхом [1] і в більшості випадків виявляється випадково, як і в нашого пацієнта. Ряд авторів [7][8][9] не виявили клінічних і рентгенологічних ознак дисплазії в родичів пацієнтів, що дозволило вважати, що в частини пацієнтів ця хвороба є первинною аберацією.…”

Clinical Case of Dentine Dysplasia Type I

Developmental dental hard tissues disorders are rarely diagnosed both in children and adults, and their treatment is a problem for dentist. Despite the fact that molecular genetics studies allow to discriminate some dentine disorders, pathogenesis of radicular dentin dysplasia is still obscure. Type I dentin dysplasia is characterized by normal or slightly coloured crowns with no roots or only rudimentary roots, reduced pulp space in permanent teeth and incomplete or total obliteration of the pulp chambers, and periapical radiolucent areas or cysts which might result in premature loss of tooth. Fortunately, teeth demonstrate higher resistance to caries than normal teeth do. Dentin dysplasia type II is characterized by yellow, brown, grey, translucent primary teeth with complete pulpal obliteration. Permanent teeth are normal or might be slightly coloured. Roots are normal in size, but pulp chamber has pulp stones. A third type of dentine dysplasia or focal odontoblastic dysplasia has radiographic aspects of the other two types of disease. Also dentine dysplasia type I has subtypes Ia, Ib, Ic and Id. Dentine dysplasia Ia is characterized by complete obliteration of the pulp, disorder of root development, and many periapical radiolucent areas. A single small horizontally oriented and half-moon shaped pulp is presented in case of dentine dysplasia Ib, roots have a few millimetres length and frequent periapical radiolucencies. Dentine dysplasia Ic is characterized by the presence of two horizontal or vertical semicircle-shaped pulpal remnants which surround dentine in pulp chamber. Also teeth have shortened roots and variable periapical radiolucencies. Dentine dysplasia Id is characterized by the distinct pulp chambers with pulp stones in the coronal third of the root canal; periapical radiolucencies are possible as well. Aim of this study was to analyse clinical case of dentine dysplasia in 8,5-year-old boy. A 8,5-year old boy patient with parents came to a dental office due to caries cavity in tooth 62. Shape of tooth crowns was not changed and teeth with no signs of mobility; white lines and spots on teeth are were detected. Based on age, the decision of orthopantomogram was made to evaluate status of primary and permanent teeth. The image showed almost obliterated pulp chamber in both erupted and developing teeth and considerably shortened, blunted and malformed roots without a visible lumen of root canals in primary teeth. Periapical lesions were found about roots of primary molars and follicles of teeth 12 and 14 without caries lesions. Patient's medical history revealed no disturbance in general health. Clinical examination of the patient's mother did not show dental hard tissues disorders, but radiograph examination revealed such disorder in the orthopantomogram. Thus, history, clinical and radiographic findings revealed this case as dentine dysplasia type I subtype 1c inherited from mother. Oral rehabilitation of patients with dentine dysplasia type I require effective prevention and a complex approach. Thus, meticulous oral hygiene measures and dietary instructions, regular check-ups twice a year were established for this patient; orthodontic consultation was recommended. Varnish «Ftoplen-LC» was applied on the permanent teeth 3 times. To prevent early exfoliation, plan of preventive measures was developed included application of fluoride varnish twice a year and fissure sealing in the premolars in 9-10 years and in the second premolars in 12-13 years. Treatment of dentine dysplasia I type that depends on patient age and severity of disease may include also filling of carious teeth, orthodontic, surgical and orthodontic treatment. In this regard, dentist has to know developmental dental hard tissues disorders and select measures to prolong the retention of affected teeth maintaining them as long as possible.

Hereditary dentin disorders include dentinogenesis imperfecta (DGI) and dentin dysplasia (DD), which are autosomal dominant diseases characterized by altered dentin structure such as abnormality in dentin mineralization and the absence of root dentin. Shields classified DGI into three subgroups and DD into two subtypes. Although they are all hereditary dentin diseases, they do not share the same causative genes. To date, the pathogenic genes of DGI type I, which is considered a clinical manifestation of syndrome osteogenesis imperfecta, include COL1A1 and COL1A2. Mutations of the DSPP gene, which encodes the dentin sialophosphoprotein, a major non-collagenous protein, are responsible for three isolated dentinal diseases: DGI-II, DGI-III, and DD-II. However, DD-I appears to be special in that researchers have found three pathogenicity genes-VPS4B, SSUH2, and SMOC2-in three affected families from different countries. It is believed that DD-I is a genetically heterogeneous disease and is distinguished from other types of dentin disorders. This review summarizes the DD-I literature in the context of clinical appearances, radiographic characteristics, and functions of its pathogenic genes and aims to serve clinicians in further understanding and diagnosing this disease.
