Abstract:
External inflammatory resorption (EIR) is the pathological destruction of external radicular structures with a multifactorial
etiology. Prompt diagnosis and meticulous intervention are obligatory to retain the salvageability of the tooth and to
circumvent the premature loss of permanent dentition. Infected pulpal tissues and microbial toxins are the mainstay of the
persistent inflammatory response in the periodontal tissues. This provokes odontoclastic activity, precipitating radicular
loss. In this report, a 17-year-old male patient reported severe pain in the mandibular right first molar. After a thorough
history and examination, the case was diagnosed as inflammatory root resorption. Nonsurgical endodontic therapy was
performed under rubber dam isolation. After adequate chemomechanical preparation, intracanal, non-setting calcium
hydroxide was utilized to arrest the resorptive process. This case enlightens the fact that mechanical debridement alone
cannot achieve the prime goal of endodontic intervention. Chemical disinfection using intracanal medicaments can magnify
the outcomes by eradicating the nidus of infection.
