Dentinal dysplasia: endodontic treatment, with case report

Microscopic analysis of molar–incisor malformation

“…4 Apical abscess without dental caries often occurs and is treated with tooth extraction or endodontic therapy. 5 In addition, unlike DD type 2 and dentinogenesis imperfecta, the gene mutation responsible for DD I has not yet been identified. 6 Other types of root malformation occur in regional odontodysplasia, 7,8 segmental odontomaxillary dysplasia, 9 vitamin-D-resistant rickets, 10,11 hypoparathyroidism, 12,13 and pseudohypoparathyroidism.…”

Dentin Dysplasia Type I: A Rare Case Report and Management Protocol

“…Extraction of infected teeth with periapical abscess can be considered as the final choice [24]. Teeth with relatively long roots can undergo endodontic treatment [9] if the pulp chamber is not obliterated. Early exfoliation of teeth and associated bone loss can necessitate techniques such as onlay bone grafting and sinus lift for placement of dental implants in adults [25].…”

“…Although delayed eruption of teeth is reported in DDI, generally teeth erupt in the normal time [8]. In DDI teeth appear to have greater resistance to caries than normal teeth [9]. In histologic examination, the enamel and immediately subjacent dentin appear normal.…”

Dentinal Dysplasia Type I: A Case Report with a 6-Year Followup

“…Endodontic treatment is contraindicated in teeth with total obliteration of root canals and pulp chambers [12]. Tidwell and Cunningham in 1979 concluded that the results of endodontic treatment might not be successful, but though challenging; they provided an alternative to extraction [6]. Orthodontic treatment is suggested; however, further resorption of the roots, loosening of teeth, and premature exfoliation may occur due to the resistance of the short roots to the orthodontic forces [14].…”

“…In DDI, teeth eruption is usually normal, but a delayed dental eruption pattern has also been reported [5]. Teeth are more resistant to dental caries, and clinically normal attrition has been found in both dentitions [6]. Because of short roots, DDI may be the extreme mobility and premature exfoliation of teeth, either spontaneously or with minor trauma [1].…”
