Endodontic Mx of radix entomolaris: a case series
This case report, published in the journal Endodontology discusses the endodontic treatment of two mandibular first molars with a radix entomolaris (RE), which are rare macrostructures. The prevalence, the external morphological variations, and internal anatomy of the RE are described.


Case 1
A 36-year-old male patient reported with a chief complaint of pain in lower-left back tooth region for 1 month. The patient revealed a history of mild intermittent pain for the past 1 month, which had increased in intensity during the past 1 week. The patient reported prolonged sensitivity to hot and cold substances. The pain was spontaneous and aggravated particularly at night.

Clinical examination revealed deep occlusal carious lesions on mandibular first molar. The tooth 36 was tender to vertical percussion. The preoperative radiograph revealed radiolucency of carious lesion involving the pulp with respect to 36. Based on the clinical and radiographic findings, a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis with respect to 36 was made, informed consent was obtained, and endodontic treatment was initiated.

Case 2

A 27-year-old female patient reported with a chief complaint of pain in lower-right back tooth region for 2 months. The patient revealed a history of mild intermittent pain for the past 2 months, which had increased in intensity during the past 2 weeks. The patient reported prolonged sensitivity to hot and cold substances. The pain was spontaneous and aggravated particularly at night.

Clinical examination revealed deep occlusal carious lesions on mandibular first molar. The tooth 46 was tender to vertical percussion. The preoperative radiograph revealed radiolucency of carious lesion involving the pulp with respect to 46 with periapical radioopacity. Based on the clinical and radiographic findings, a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis and condensing osteitis with respect to 46 was made and endodontic treatment was initiated.
