Chlorhexidine is a widely used antiseptic and disinfectant in medical and nonmedical environments. Compared to its ubiquitous use, allergic contact dermatitis from chlorhexidine has rarely been reported and so its sensitization rate seems to be low. The prevalence of contact urticaria and anaphylaxis due to chlorhexidine remains to be unknown. This case report presents a case of urticaria due to oral use of chlorhexidine. The adverse reaction was confirmed by skin prick test.

Internal inflammatory root resorption is an uncommon pathology that can progress to the periradicular vicinity. It is frequently asymptomatic and only discovered during a radiological screening. Appropriate and timely diagnosis is extremely crucial in tackling these cases. A perforating internal resorptive cavity in the distal root of the mandibular first molar was successfully managed using a sandwich concept of sectional apical obturation with gutta-percha and Bioceramic sealer followed by the placement of mineral trioxide aggregate in the resorptive cavity.
