Objective : The aim of this study was to investigate risk factor, precaution and treatment of aspirated foreign body during dental procedure. Material and Methods : Twenty cases of accidental aspiration of the foreign body, which removed by bronchoscopy at the Asan Medical Center between 2008 and 2012, were analyzed retrospectively. Results : Ten cases of accidental aspiration were occurred during dental procedure. Symtoms include cough(65%), dyspnea(50%), sputum(25%) and wheezing(25%). The most common location of foreign body was right bronchial tree(50%), left bronchial tree(45%) and carina(5%). Patients risk factors were chronic obstructive pulmonary disease, lung cancer, pulmonary tuberculosis, esophageal cancer and vegetative state. Conclusion : Accidental aspiration or swallowing of dental instrument or material is not uncommon accidents in dental practice. Most foreign bodies enter into gastrointestinal tract spontaneously. But aspiration into broncho-trachea can be more serious events and must be treated as an emergency situation. Prompt emergency treatment and removal of the foreign body is necessary to avoid complication. Dentists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental procedures.

Purpose: Foreign body aspiration in children is emergent and can cause serious complications. This study aims to show the clinical characteristics of foreign body aspiration and to analyze the clinical cases of delayed diagnosis to predict and prevent complications. Methods: We retrospectively reviewed the medical records of 63 children (48 in Inha University Hospital and 15 in Gachon University Gil Medical Center) who were diagnosed with foreign body aspiration through bronchoscopy from 1996 to 2017 in Incheon City, and analyzed clinical characteristics. Patients were divided into 3 groups: those were diagnosed within 24 hours, delayed after 24 hours, or delayed more than 7 days according to time elapse from the time of foreign body aspiration, and clinical characteristics of each group were compared. Results: Aspiration occurred in 58.7% at 1 year and 15.9% at 2 years. Cough (65.1%) and coarse breathing sound (41.3%) were most common, and radiologic findings were commonly presented as emphysema on the affected side (41.3%). Nuts were most common (42.9%), and there was no difference in the frequency between the right and left main bronchi. The documented history of foreign body aspiration was more frequently found in the early diagnosed group; however, sputum, fever, and complications were more frequent in the delayed diagnosed group. Conclusion: If a patient with respiratory disease has persistent fever or sputum, foreign body aspiration should be suspected.

Aspiration of foreign bodies into the tracheobronchial tree is unusual in adults and it may result in Proximal airway obstruction and acute life-threatening asphyxia. It can be diagnosed by history of aspiration or visualizing the foreign body by chest roentgenogram or bronchoscopy. But it is rarely considered in adults with subacute or chronic respiratory symptoms without a definite history which suggests an aspiration. A 70-year-old woman was admitted to the hospital due to productive cough for two months and dyspnea which aggravated since the day before admission. Chest X-ray showed Pneumonic infiltration on left upper lobe and right lower lobe. Despite several days of conventional therapy, the patient complained of severe dyspnea and wheezing. We performed chest CT to rule out endobronchial stenosis, and it revealed the narrowing of left main stem bronchus compatible with endobronchial tuberculosis. Fiberoptic bronchoscopy for confirmation disclosed a $3.2{\times}0.7{\times}0.2$cm sized foreign body located longitudinally at the left main stem bronchus. We removed it with alligator forcep and it proved In be a piece of artificial denture. The patient remembered losing it while severe coughing on the day before admission. The microscopic examination of bronchial washing fluid revealed numerous acid fast bacilli. After removal of the foreign body, the patient showed marked improvement in symptom and pulmonary function test. Here we report a case of Pulmonary aspiration of foreign body which is confused with endobronchial tuberculosis with a review of the literature.

Background: This retrospective study investigated the incidence rate of accidental foreign body aspiration and ingestion according to patient sex, age, and dental department. This study aimed to verify whether the incidence rate is higher in geriatric than in younger patients and whether it is different among dental departments. Methods: Accidental foreign body aspiration and ingestion cases were collected from electronic health records and the safety report system of Yonsei University Dental Hospital from January 2011 to December 2017. The collected data included patients' age, sex, medical conditions, treatment procedures, and foreign objects that were accidentally aspirated or ingested. The incidence rate was calculated as the number of accidental foreign body aspirations and ingestions relative to the total number of patient visits. Differences depending on the patients' sex, age, and dental department were statistically identified. Results: There were 2 aspiration and 37 ingestion cases during the 7-year analysis period. The male to female incidence ratio was 2.8:1. The incidence rate increased with age and increased rapidly among those aged 80 years or older. Seven of the 37 patients with accidental foreign body ingestion had intellectual disability, Lou Gehrig's disease, dystonia, or oral and maxillofacial cancer. The incidence rate was highest in the Predoctoral Student Clinic and the Department of Prosthodontics. The most frequently swallowed objects were fixed dental prostheses and dental implant components. Conclusion: The incidence rate of accidental foreign body aspiration and ingestion differed according to patient sex, age, and dental department. Dental practitioners must identify high-risk patients and apply various methods to prevent accidental foreign body aspiration and ingestion in dental clinics. Inexperienced practitioners should be particularly careful.

There are a lot of dental emergency situation. Especially on disabled or pediatric patient with negative behavior, accidental aspiration or ingestion of foreign body (ex: dental instrument) is one of the common accidents in dental procedure. Dentists and dental hygienists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental treatment, especially on the disabled. This is a case of an accident during the dental treatment of 14-year-old female patient with cerebral palsy. During scaling, prolonged retained primary tooth which had resorbed roots was fell into left bronchi. So we tried to remove the crown by endotracheal approach. Most ingested foreign bodies pass through the gastrointestinal tract spontaneously, but some of them need endoscopic or surgical removal. Moreover aspiration into broncho-trachea can be more serious events and must be treated as emergency situation.

The practice of oral surgery or other dentistry possesses the danger of causing the loss of foreign bodies used within the oral cavity. If such foreign bodies would be lost, they could enter the viscera through the esophagus or tracheobroncheal tree. Ingestion is four times as frequent as aspiration and 80% to 90% of ingested foreign bodies will pass through the body spontaneously. Once the aspiration or ingestion of foreign bodies is happened, a dental procedure should be discontinued immediately. If symptoms of respiratory distress, including coughing, wheezing, or stridor, are present, a patent airway should be maintained, oxygen administered, and ventilation supported if necessary. The PA chest radiograph will identify the objects in the lung, esophagus, or stomach. Ingested gastrointestinal foreign bodies may be managed by observation, endoscopy, and or surgical intervention and aspirated tracheobroncheal foreign bodies may be managed by bronchoscopy, and or surgical intervention. This case report describes the management of ingested or aspirated foreign bodies happened to the three patients during intraoral treatment. we recommend that the preventive method of ingestion or aspiration of the dental foreign bodies should be performed prior to intraoral treatment and the immedieate measures should be carried out after ingestion or asipiration of it.

Foreign body aspiration in dental clinics is the most common cause of respiratory emergencies. There are no reports on foreign body aspiration during dental treatment under stable general anesthesia because the patient neither has voluntary movements nor reflex actions. This is a case report on the fall of a prosthesis in the larynx, which occurs rarely under general anesthesia. During the try-in procedure, the prosthesis slid from the surgeon's hand and entered the retromylohyoid space, and while searching for it, it passed down the larynx to the endotracheal tube balloon, leading to a dangerous situation. The prosthesis was promptly removed using video-assisted laryngoscope and forceps, and the patient was discharged without any complications.
