“…Chronic use of bismuth-containing products can result in encephalopathy, whereas acute toxicity can manifest as nephrotoxicity [24]. Blackening of the tongue and teeth has been reported as a harmless side effect of bismuth toxicity [25]. Our patient had dark teeth, with no change in tongue coloration and no evidence of gingival bismuth line (Fig.…”

Bismuth encephalopathy- a rare complication of long-standing use of bismuth subsalicylate

et al. 2019

Background: Drugs containing bismuth, although usually safe, may rarely cause neurotoxicity. Case presentation: We describe the case of a 44-year-old woman treated with bismuth subsalicylate for about 20 years, who developed abnormal behaviour and postural instability in two weeks. On examination, she had greyish discoloration of teeth, was confused and presented generalized myoclonic jerks. In the next days, her clinical condition deteriorated, with a reduction in alertness and more exuberant myoclonus. Brain MRI was unremarkable. CSF revealed mild elevation of protein content (47 mg/dL; reference range: 15-45 mg/dL) and elevation of white blood cell count (10/μL). Bismuth levels in urine (375 μg/L), serum (260 μg/L) and CSF (21.4 μg/L) samples were highly above the threshold for toxicity. Following supportive treatment and bismuth discontinuation, she made a full recovery within weeks. Conclusions: Although rare, bismuth encephalopathy should be considered in patients presenting with subacute encephalopathy and myoclonus. This encephalopathy can be subacute even after a chronic exposure. Cessation of bismuth can lead to a complete resolution in weeks.

“…Oral mucosal damage due to chemicals is often the result of an unintentional therapeutic error by clinicians during dental procedures as a wide variety of dental agents can cause mucosal harm 2 . To the best of our knowledge, this is the first case report that describes phosphoric acid‐ and HEMA‐induced gingival necrosis following crown cementation, and its management.…”

Iatrogenic acid‐induced gingival recession during crown cementation: A case report

Accidental contact of various chemicals in dentistry may cause damage to the gingiva. A male patient presented for a full mouth rehabilitation with ceramic crowns. The patient underwent the steps of ceramic crown preparation uneventfully. At the time of crown delivery, cotton rolls were placed in several vestibular areas for isolation. They were regularly changed during different steps of etching and cementation process, which included the use of Multilink Primer B (Ivoclar Vivadent™). On removal of the cotton roll in the area of upper right canine, the gingival tissues appeared blanched and grayish white. The cotton roll was found to have absorbed some etching material in it. As the patient was asymptomatic, he was dismissed. Two weeks later, the patient presented with inflammation and gingival recession in the same area. Initially, he was treated palliatively, and subsequently, he received a connective tissue graft on the upper right canine. This case report showed that acid etching material used during the prosthodontic cementation may have caused a gingival recession, which was successfully treated with tunnel flap and connective tissue graft. Optimal isolation of the operative field should be performed to avoid this problem.

“…In addition, microwave ovens have been associated with an increased frequency of thermal burns due to their ability to cook food that seems to be cool or at least edible on the exterior although extremely hot in the interior. 1 The misuse of microwave ovens can be particularly hazardous to vulnerable individuals, such as infants, who can suffer palatal burns from microwave-heated infant’s milk; 2 and the elderly, occasionally causing significant thermal injuries that may result in emergency scenarios such as laryngeal damage. 3 Systemic diseases such as diabetes can be related to oral mucosal dysesthesia, which may predispose the occurrence of thermal burns in the mouth, causing significant more damage than what the patient actually feels.…”

Successful GaAlAs low-level laser therapy of self-inflicted thermal burns of the palate

Thermal burns of the oral cavity usually arise from ingestion of hot foods or beverages. A 38-year-old female patient presented with two painful ulcerative erythematous patches of the palate. The patient was consulted on the same day lesions appeared. Medical history was unremarkable. Clinically significant self-inflicted injuries may result in wide ulcers in the mouth and usually do not take less than 2 weeks to heal, whereas our patient, treated with low-level laser therapy, had a complete response in day 4, after 2 days of treatment. The fact that multiple lesions were present signaled against the World Health Organization exclusion diagnosis of erythroplakia for red patches. A traumatic ulcer, regardless of its cause of origin, usually heals within 2 weeks, after the source of injury is resolved. A thermal burn in the oral cavity usually takes longer than that to heal, but whenever this time frame is not respected, the suspicion of a potentially malignant disorder should always arise, and a biopsy should be performed. The present case showed two painful thermal burns with great results in terms of speeding up the relieve of symptoms and healing time with soft laser as opposed to the traditional treatment with oral topical corticosteroid.
