of pain and facial swelling involving her mandible, in particular the mandibular left
quadrant. She described the discomfort as beginning approximately 3 to 4 weeks before
her appointment. She stated that several of her teeth were deemed unrestorable by
her referring oral health care provider and needed extraction. Her medical history
was significant for hypertension, arthritis, asthma, and a heart murmur. Clinical
examination revealed an edentulous area in the maxillary left molar region corresponding
to teeth nos. 14 and 15. Several teeth showing recurrent caries were also observed.
Extraoral examination revealed soft-tissue expansion of the mandibular left region
with slight involvement of the inferior aspect of the nasolabial fold (Figure 1). The mandibular left quadrant showed swelling in the vestibule compared with the
right side (Figure 2). Radiographic images were obtained, and multiple mixed radiolucent-radiopaque lesions
were identified. The central portions of these lesions consisted of sclerotic, hyperostotic
material. These central zones were surrounded by well-defined radiolucencies of various
sizes. The roots of some of the mandibular premolars and molars appeared broadened
and bulbous (Figure 3). Despite these lesions, all of the teeth tested vital with the exception of the
mandibular left first and second molars.
