A 47-year-old female patient presented to the primary care clinic for routine dental check-up. Following intra-oral examination, generalized periodontitis and missing teeth were observed. Orthopantomography (OPG) was advised for evaluation of the periodontal status and for further treatment planning. OPG revealed multiple thread-like, irregular, crisscross radiopacities measuring a few millimetres to 2 cm distributed bilaterally across the premolar and molar regions of both jaws, maxillary sinuses, and lateral orbital surfaces (Figure 1). Identification of proximal caries around maxillary left third molar was difficult owing to the overlapping of these radiopacities (yellow arrow indicating proximal caries). The supporting structures of the tooth such as periodontal ligament space, lamina dura, and interdental bone were obscured around the premolar-molar area leading to difficulty in accurate interpretation. Upon inquiry, the patient disclosed undergoing facial rejuvenation with gold threads 4 years previously. Gold facial rejuvenation involves inserting 3–5-mm 24-carat gold threads into subdermal soft tissues to enhance skin tone, elasticity and reduce wrinkles.¹
