“…Detection of a cervical lingual crack extending from the external surface to the pulp chamber (Fig. ) supports the notion that micro‐CT imaging can help to establish post‐extraction diagnosis of the cause of periapical infections, such as cracks or pores that are not visible in conventional radiographs . In the present study, the complex morphology of the root canal anatomy of the DD1c specimen provides an insight into the futility of attempting non‐surgical root canal therapy should apical periodontitis develop.…”

Dentine dysplasia type 1 is a rare and complex dental anomaly. Our aim was to conduct a morphometric assessment of a dentinal dysplasia type 1c (DD1c) caries-free mandibular second molar, extracted due to symptomatic apical periodontitis. Controls consisted of five intact mandibular second molars. Microcomputed tomography analysis showed that the DD1c volume % for enamel, dentine/cementum and pulp chamber fell in the 0.36th, 99.97th and 0.09th percentiles of the control teeth (P < 0.01). It also revealed an extremely complicated root canal system in the DD1c tooth with a varying degree of dentine mineralisation and aberrant dentine deposition in the pulp chamber. A crack extending from the external tooth surface to the pulp chamber was identified as a potential site for microbial invasion. Clinical implications include preventive measures and early intervention in reversible pulpitis. Conclusion: Micro-CT imaging can be useful in establishing post-extraction diagnosis of cracks and phenomic characterisation of tooth anomalies.

“…These findings are not only consistent with but also expand on the previous studies using microCT to describe the morphology of MRIM 3,20 . The source of odontogenic pain in children with MRIM may be from microcracks or microporosities 21,22 . The current study yields information that may explain the ingress of microorganisms from the oral environment that can utilize the tract or communication with the pulp, causing pulpitis and potentially necrosis.…”

Although the etiology of MRIM is yet to be determined, epigenetic changes caused by systemic insults in the first 4 years of life are likely to influence the root development of permanent first molars and primary second molars.…”

BackgroundMolar‐root incisor malformation (MRIM) is a rare dental anomaly featuring constricted cervical margins and tapered, narrow root and pulp morphology, often associated with severe toothache and infection.AimThe aim of this study was to determine the prevalence of MRIM in children seen in a specialist paediatric dental unit of a tertiary referral hospital and to describe the characteristics of affected individuals.DesignThis study was an audit of children attending from November 2020 to November 2021. Radiographs were used to identify individuals with MRIM, and clinical data were collated. In addition, histology and microcomputed tomography (microCT) imaging were performed on teeth extracted from an affected individual.ResultsThe prevalence of MRIM was five cases of 1054 children examined (0.47% or 1:210). The permanent first molars were affected in all five children and the primary second molars in two children; all children had medical comorbidities and multiple exposures to general anesthesia before 4 years of age. In addition, histological and microCT analyses displayed numerous microchannels connecting the pulp chamber to the external surface of the tooth at the furcation.ConclusionsMolar‐root incisor malformation is an uncommon dental anomaly affecting paediatric patients with multiple comorbidities and is characterized by porosities extending from the pulp chamber to the external tooth surface, predisposing the risk of bacterial ingress from the oral cavity into the pulp chamber. Early detection may prevent atypical odontogenic facial pain and infection.
