The aim of this work is a review of recent information about halitosis among patients using prosthetic dentures. Halitosis is a condition in which an unpleasant smell comes out of the oral cavity, which is caused mainly by volatile sulfur and non-sulfured compounds. The etiology of halitosis may be intra- or extra-oral; in most patients, however, it is due to the activity of microorganisms in the oral cavity. The problem of the occurrence of halitosis has accompanied patients for many years. In dental prosthetics, the problem of halitosis occurs in patients using removable or fixed dentures. In both cases, new niches for the development of microorganisms may be created, including those related to halitosis. It should be noted that dentures—both fixed and removable—are a foreign body placed in the patient’s oral cavity which, in case of insufficient hygiene, may constitute a reservoir of microorganisms, causing this unpleasant condition. Conventional treatment of intraoral halitosis reduces microbial activity via chemical and/or mechanical action. Currently, the search for new strategies in the treatment of halitosis is in progress. One idea is to use photodynamic therapy, while another is to modify poly(methyl methacrylate) (PMMA) with silver and graphene nanoparticles. Additionally, attempts have been made to combine those two methods. Another unconventional method of treating halitosis is the use of probiotics.

Purpose: We report a case of keratitis that improved after removal of a causative plant foreign body from below the posterior surface of an opaque cornea. The foreign body was revealed by anterior segment optical coherence tomography (AS-OCT) and gonioscopy.Case summary: A 79-year-old woman was referred with an impression of left-eye keratitis; the eye had been injured by a branch of a tangerine tree 1 month prior. She had been given the usual topical antibiotics by a local clinic, but they were ineffective. At her initial visit, her visual acuity was only hand motion in the left eye; slit-lamp examination revealed a 3 × 3-mm corneal infiltration with a hypopyon in the anterior chamber. Despite administration of strong topical antibiotics on an hourly basis, the corneal lesion worsened. AS-OCT and gonioscopy revealed a small foreign body below the posterior surface of the cornea; this was surgically removed. The corneal opacity and corneal epithelial defects dramatically improved, and the hypopyon disappeared.Conclusions: The possibility of a residual foreign body should be considered if trauma precedes infectious keratitis that does not improve with conventional treatment and the posterior surface of the cornea is not visible because of corneal opacity. In such a case, AS-OCT and gonioscopy can be useful.

Abstract Background Foreign body ingestion is a common problem in pediatrics. Each foreign body can present its’ own unique challenges during removal, and we present the management of an ingested Spotted Tussock Moth (Lophocampa maculata), more commonly known as a caterpillar. Case presentation An 18-month-old boy presented to the emergency department with difficulty handling secretions and odynophagia. It was reported he had placed a caterpillar in his mouth and then spat it out. On examination, hundreds of miniscule filaments (setae) were seen embedded in his lips and tongue. Our service was consulted out of concern for airway involvement. The patient was taken to the operating room where a direct laryngoscopy under general anesthesia with spontaneous ventilation was performed to confirm the setae were confined to the anterior tongue and lips. Once we were satisfied the airway was stable, the airway was secured, and we then began to remove the setae. The initial method used was to use Adson-Brown forceps to remove the setae, however this proved difficult and time-consuming given the volume of setae and how thin the setae were. Ultimately, a more effective technique was developed: a 4 × 4 AMD-RITMES® gauze was applied to the mucosa in order to dry up any secretions and then a piece of pink, waterproof BSN medical® tape was applied to the mucosa. After 3 s of contact it was removed. This technique was then repeated and was used to remove the vast majority of the setae. Conclusion To our knowledge, we have described the first technique to remove the caterpillar setae from the oral cavity mucosa in a fast, safe and efficient manner.
