Medical Research: Emerging Concepts and Applications Vol. 1

The “hot tooth” is a clinically challenging endodontic condition commonly associated with symptomatic irreversible pulpitis and difficulty in achieving profound pulpal anaesthesia. This chapter discusses the diagnostic and therapeutic considerations involved in managing such teeth during emergency endodontic care. The clinical problem is explained through inflammation-related peripheral sensitisation, tissue acidosis, altered sodium channel activity, accessory innervation and psychological factors that may reduce the effectiveness of conventional local anaesthetic techniques. Emphasis is placed on careful diagnosis using patient history, thermal and electric pulp testing, percussion, palpation and radiographic assessment, as well as differentiation from conditions such as reversible pulpitis, cracked tooth syndrome, dentinal hypersensitivity, symptomatic apical periodontitis and non-odontogenic pain. The chapter outlines a stepwise approach to management, beginning with patient counselling, anxiety assessment and objective confirmation of anaesthetic depth. When a primary inferior alveolar nerve block is inadequate, supplemental methods such as buccal infiltration, intraosseous injection, periodontal ligament injection and intrapulpal anaesthesia may be considered according to clinical need. Pharmacological premedication, postoperative pain control, irrigation, disinfection and definitive endodontic treatment are also discussed. The chapter further considers the selected use of vital pulp therapy and the importance of patient-centred communication. Overall, the hot tooth should be approached as a predictable clinical challenge requiring accurate diagnosis, staged anaesthetic planning and evidence-informed endodontic management.
