Introduction:

Necrotizing periodontitis (NP) is an acute inflammatory disease that can appear suddenly and with fast destruction of periodontal tissues. The most relevant clinical findings are necrosis and ulcer at the interdental papilla, gingival bleeding, pain, bone destruction, and, in severe cases, bone sequestrum could occur. Although the primary etiological factor is the accumulation of bacterial biofilm, risk factors like systemic and/or psychological diseases could affect the host immune response playing an important role in the development of NP.

Objective:

Present the resolution of a PN case with a multidisciplinary and conservative approach.

Case presentation:

A 22-year-old female patient was referred to the Dental Clinics Center of the University of Talca (Talca, Chile) with apparent psychological stress and smoker. She reports intense and persistent pain in the anterior teeth with spontaneous bleeding and halitosis for 2 weeks.The treatment consisted of the evaluation of the systemic condition and the management of the acute phase, the etiological phase, and subsequent corrective phase for the surgical correction for the sequels. This case has 2 years follow-up with a rigorous periodontal maintenance regimen, re-evaluating the periodontal tissues, motivating, and reinforcing oral hygiene.

Conclusions:

This case report contributes to the diagnosis and therapeutic options that the professional has in front of the sequels that occur in cases of NP, which, although it is not a frequent pathology, can quickly worsen and increase tissue damage.
