Endodontic treatment of dentin dysplasia type I D

Abstract

Dentin dysplasia (DD) Type I is a developmental condition affecting dentin, inherited in an autosomal‐dominant pattern or occurring due to a new mutation. Whilst the crowns of DD Type I affected teeth appear clinically normal, the roots are blunt and shortened. Pulp necrosis and periapical pathoses may be seen in the absence of obvious causes. Pulp stones and calcifications are frequently encountered. Endodontic management of DD may be challenging. A case of DD Type I, sub‐classification d, in which spontaneous irreversible pulpitis developed on three mandibular incisors is documented. The case was managed by conventional endodontic treatment. Knowledge of this uncommon dental condition may assist dentists to adequately diagnose and manage these cases. Extraction should not be considered the first‐line treatment option when sufficient root length is available to attempt endodontic treatment. Referral for medical evaluation is recommended to rule out systemic diseases which may mimic this condition.

Current endodontic practice and use of newer technologies in Australia and New Zealand

“…24 Comparatively, usage was lower among GDPs surveyed in Malaysia (23.4%) 5 and Denmark (69%), 7 but higher in South Africa (96%). 6 The use of EAL by Group D was also high in this study, similar to or higher than GDPs surveyed in Malaysia, 5 New Zealand, 17 Denmark, 7 the USA, 21 Iran 67 and the UK. 68 Group E's high EAL usage was similar to endodontists surveyed recently in Nepal 69 and the UK.…”

“…This study demonstrated the continued uptake of endodontic technologies compared with previous surveys, although usage varied geographically. In this study, 86.3% of Group D used loupes and 5.8% used the DOM, higher than, respectively, 33% and 6% in South Africa, 6 75% and 2% in the USA, 21 7.4% and 1.2% in Malaysia, 5 and 17.1% and 3.2% in Turkey 18 …”

“…However, usage by Group D (89.9%) was higher than 74.5% reported in New Zealand 17 and a marked increase from 22% in Australia two decades ago 24 . Comparatively, usage was lower among GDPs surveyed in Malaysia (23.4%) 5 and Denmark (69%), 7 but higher in South Africa (96%) 6 …”

“…New technologies have emerged in the last few decades including the dental operating microscope, 1 nickel‐titanium (NiTi) instruments, 2 and calcium silicate‐based materials (CSBMs), 3,4 that have substantially changed endodontic clinical practice. However, dental dam isolation is a low‐cost part of the armamentarium that continues to be used at low rates (20%–40%) by general dentists (GDPs) in endodontics in some parts of the world 5–7 despite being considered the standard of care for many years 8,9 . Other recent studies show much higher usage rates 10,11 which approach the almost universal usage reported by endodontists in some countries 5,12–14 …”

Global cone‐beam computed tomography adoption, usage and scan interpretation preferences of dentists and endodontists

“…Among non‐endodontic respondents in this survey, on‐site access (25.9%) was also higher than in surveys of general dentists in the Netherlands (8.4%) (van der Zande et al., 2015) and New Zealand (12.3%) (van der Zande et al., 2018). The usage of CBCT for any dental indication in this group (45.4%) was higher than reported in previous studies in Lithuania (17.3%) (Masyte et al., 2021), New Zealand (18.2%) (Loch et al., 2019), South Africa (4%) (Buchanan et al., 2019) and Malaysia (1.6%) (Wong et al., 2019).…”
