Accidental swallowing of orthodontic expansion appliance key

The Nature of Adverse Events in Dentistry

OBJECTIVES

Learning from clinical data on the subject of safety with regards to patient care in dentistry is still largely in its infancy. Current evidence does not provide epidemiological estimates on adverse events (AEs) associated with dental care. The goal of the dental practice study was to quantify and describe the nature and severity of harm experienced in association with dental care, and to assess for disparities in the prevalence of AEs.

METHODS

Through a multistaged sampling procedure, we conducted in-depth retrospective review of patients' dental and medical records.

RESULTS

We discovered an AE proportion of 1.4% (95% CI, 1.1% to 1.8). At least two-thirds of the detected AEs were preventable. Eight percent of patients who experienced harm due to a dental treatment presented only to their physician and not to the dentist where they originally received care.

CONCLUSIONS

Although most studies of AEs have focused on hospital settings, our results show that they also occur in ambulatory care settings. Extrapolating our data, annually, at least 3.3 million Americans experience harm in relation to outpatient dental care, of which over 2 million may be associated with an error.

PRACTICAL IMPLICATIONS

Measurement is foundational in enabling learning and improvement. A critical first step in preventing errors and iatrogenic harm in dentistry is to understand how often these safety incidents occur, what type of incidents occur, and what the consequences are in terms of patient suffering, and cost to the healthcare system.

Accidental ingestion of a fractured piece of orthodontic aligner: a case report

BACKGROUND

Ingestion and aspiration of orthodontic devices are rare occurrences, typically associated with components such as expansion keys, archwire segments, dislodged fixed appliances (including brackets, buccal tubes, and bands), as well as fractured metal or plastic appliances. This article describes the clinical diagnosis and treatment process of a case of accidental ingestion of a fractured piece of orthodontic aligner.

CASE PRESENTATION

A 31-year-old female under orthodontic treatment by aligners accidentally ingested a fractured piece of the aligner. The special difficulty of this case is that the transparent orthodontic aligner has a low radiopacity. At the beginning, no foreign body was found in the commonly used soft tissue window, causing difficulty in its location until greyscale was adjusted to lung window. The 2-centimeter fractured piece was taken out under anesthesia and endoscopic surgery.

CONCLUSION

Materials with low radiopacity should be read with a lower grayscale range. Fractured orthodontic appliances with low retention force should not continue to be worn until consultation with attending doctor.

Frequency and Management of Accidental Incidents in Orthodontics

BACKGROUND

The present study aims to define through questionnaires the frequency and the variety of accidental incidents occurring in orthodontic clinical practice among Greek practicing orthodontists.

METHODS

A questionnaire survey was conducted among orthodontists from the registry of orthodontists in Greece. The questionnaire was divided into two parts. The first part involved three questions relating to the socio-demographic status and the background of the orthodontist, and the second part concerned exclusively the frequency of accidental incidents that have occurred during clinical practice with three possible answers: never, once, more than once.

RESULTS

From the 200 initially distributed questionnaires, 124 were finally completed and sent back (response rate: 62%). The results showed that orthodontists with more years of clinical practice had faced more accidental incidents. Among the ingestion incidents caused by foreign objects, the most frequently occurring was the ingestion of elastic separators, followed by the ingestion of elastic ligatures and ingestion of hooks. The most commonly reported traumatic incidents were the trauma-lesion of the mucosa by the orthodontic wire or part of it, followed by trauma-lesion by hooks and wire ligatures. The reported number of incidents with further complications and with patients referred to an emergency room was very low.

CONCLUSIONS

The results of the present study determined a high frequency of accidental incidents among Greek orthodontists. The longer clinical experience was accompanied by more accidental incidents. Orthodontists, like other health professionals, must learn and continuously update their knowledge regarding the management protocols of medical emergencies.

Colonic Perforation: A Case Report of a Rare Delayed Complication Due to Accidental Swallowing of Denture

Removable partial dentures are the most common object found in elderly patients presenting with a history of foreign body ingestion. These patients will usually present within a week with complications if the foreign body gets impacted in the gastrointestinal tract. In this case report, we present a rare delayed complication in the form of colonic perforation that presented three years after swallowing a denture, with the emphasis on how to suspect and manage these patients.

Effects of Accidental Swallowing of Orthodontic Appliance on Gastrointestinal Tract and Airway: An Evidence-Based Review of Case Reports

Background:

Contemporarily, the use of innovative orthodontic appliances or their components has increased for safer, quicker results, and more comfort of the patient. But, researchers rarely highlight the potential demerits of accidental ingestion of these appliances. Thus, the present study aimed to investigate the evidence-based literature on the accidental swallowing of these appliances and their effect on the gastrointestinal tract (GIT) and airway.

Method:

An electronic search was performed on PubMed, Medline, Scopus, The Cochrane Library, and EMBASE until April 11, 2021. Methodological quality and synthesis of case series and case report tool (MQCC) was applied to determine the quality of these case reports and series. The outcome variable was to assess its effect on airway and GIT, and methods of removal of these foreign bodies. Meta-analysis was not performed as the study included case reports and case series in which no control groups were present.

Results:

Out of 113 case reports and series, 29 articles were included in this systematic review. Only 31% of articles have satisfied the MQCC scale and maintained as high-quality case reports, 43% of articles were medium to high quality, and 26% designated as low quality.

Conclusions:

Eighty percent of the accidental ingested orthodontic appliances that pass uneventfully through the gastrointestinal system require a fiber-rich diet and laxatives. A total of 10% to 20% lacerates oral, pharyngeal, and gastrointestinal mucosa result in pain, bleeding requires laryngoscope, endoscopically and laparoscopy with use of Magill’s forceps. Only 1% of cases have presented with a high morbidity and mortality alarming for surgical removal of ingested component. Thus, the precautions to be taken to overcome such incidences are tying silk thread to activation key, use of recent bonding method, use of contrast colors of removable appliances as the color merges with mucosal color, and operator position should be 7 O′ clock.

Clear aligner VS fixed self-ligating appliances: Orthodontic emergency during 2020 COVID-19 pandemic

Introduction

The aim was to investigate the type, incidence, and degree of orthodontic-related emergencies in orthodontic patients during the 2020 coronavirus disease 2019 pandemic and compare the different effects of clear aligner (CA) and fixed self-ligating appliances on the orthodontic emergency.

Methods

The questionnaire was based on emergencies in orthodontics. The responses of 428 patients between the ages of 12 and 38 years (20.4 ± 7.03) in orthodontic treatment during 2020 were examined.

Results

The gender, age, and the type of orthodontic appliance affect the incidence of orthodontic-related emergencies. Female or adolescent patients treated by self-ligating appliances showed a higher incidence of emergencies. The patients treated by CA exhibited a much lower incidence of emergency. Appliance detachment and mucosa injury were very common in respondents, whereas accidental ingestion and other rare emergencies were less common. The most common reason leading to appliance detachment was chewing hard food. Interestingly, the fixed self-ligating appliances group was also affected by the accidental detachment of appliances to a large extent. The CA and self-ligating groups showed an almost equal incidence of accidental ingestion. The most common foreign body was elastics in both groups. However, the self-ligating group could accidentally ingest dangerous foreign bodies, such as archwires, miniscrews, and welded attachments.

Conclusions

Orthodontic-related emergencies were very common in patients. The CA could effectively reduce orthodontic-related emergencies. Dentists should raise patients’ awareness of proper appliance care. A proper and standard protocol should be developed.

Patient Safety Incidents and Adverse Events in Ambulatory Dental Care: A Systematic Scoping Review

BACKGROUND

There have been efforts to understand the epidemiology of iatrogenic harm in hospitals and primary care and to improve the safety of care provision. There has in contrast been very limited progress in relation to the safety of ambulatory dental care.

OBJECTIVES

To provide a comprehensive overview of the range and frequencies of existing evidence on patient safety incidents and adverse events in ambulatory dentistry.

METHODS

We searched MEDLINE and EMBASE for articles reporting events that could have or did result in unnecessary harm in ambulatory dental care. We extracted and synthesized data on the types and frequencies of patient safety incidents and adverse events.

RESULTS

Forty articles were included. We found that the frequencies varied very widely between studies; this reflected differences in definitions, populations studied, and sampling strategies. The main 5 PSIs we identified were errors in diagnosis and examination, treatment planning, communication, procedural errors, and the accidental ingestion or inhalation of foreign objects. However, little attention was paid to wider organizational issues.

CONCLUSIONS

Patient safety research in dentistry is immature because current evidence cannot provide reliable estimates on the frequency of patient safety incidents in ambulatory dental care or the associated disease burden. Well-designed epidemiological investigations are needed that also investigate contributory factors.

The upper airway volume effects produced by Hyrax, Hybrid-Hyrax, and Keles keyless expanders: a single-centre randomized controlled trial

OBJECTIVE

To assess upper airway volume changes after rapid maxillary expansion (RME) with three different expanders.

TRIAL DESIGN

Three-arm parallel randomized clinical trial.

METHODS

Sixty-six patients, 10-16 years old, in permanent dentition, with maxillary transverse deficiency were recruited and assigned with block randomization (1:1:1 ratio) and allocation concealment to three groups of 22 patients each (Hyrax, Hybrid-Hyrax, and Keles keyless expander). The primary outcome (overall upper airway volume change) and secondary outcomes (volume changes in the nasal cavity, nasopharynx, oropharynx, and hypopharynx) were blindly assessed on the initial (T0) and final (T1, 6 months at appliance removal) cone beam computed tomography. Differences across groups were assessed with crude or adjusted for confounders (gender, age, growth stage, skeletal pattern, baseline airway volume, and amount of expansion) linear regression models.

RESULTS

Fifty-one patients were analysed (19, 19, and 13 in the Hyrax, Hybrid-Hyrax, and Keles groups). Maxillary expansion resulted in considerable increases in total airway volume in the Hybrid-Hyrax group (+5902.1 mm3) and less in the Hyrax group (+2537.9 mm3) or the Keles group (+3001.4 mm3). However, treatment-induced changes for the primary and all secondary outcomes were of small magnitude and no significant difference was seen among the three expanderes in the total airway volume in either crude or adjusted analyses (P > 0.05 in all instances). Finally, among pre-peak patients (CVM 1-3), the Hybrid-Hyrax expander was associated with significantly greater increases in total airway volume compared to the Hyrax expander (P = 0.02).

CONCLUSIONS

RME resulted in relatively small increases in total upper airway volume and its separate compartments, with mostly no statistically significant differences across the Hyrax, Hybrid-Hyrax, and Keles groups.

LIMITATIONS

Significantly greater attrition was found in the Keles group due to appliance failure. The current trial might possibly be under-powered to detect differences between groups, if such exist.

HARMS

Keles expanders blocked during activations and required substitution for completion of treatment.

PROTOCOL

The protocol was not published before trial commencement.

Duodenal obstruction due to accidental swallowing of a dental prosthesis: a case report and review of the literature

BACKGROUND

Artificial dentures are the most common object ingested by elderly patients and account for 4-18% of all foreign body ingestions. Denture impaction in the small bowel is a rare phenomenon. Surgery of the duodenum is difficult, so endoscopy should be the first choice in these patients. There are very rare case reports on denture ingestion-induced duodenal obstruction or perforation, so the aim of this publication was to show a rare case of accidental ingestion of a dental prosthesis with duodenal obstruction and also perforation that could not be treated with endoscopic management and was managed with duodenal kocherization and gastrostomy.

CASE PRESENTATION

A 47-year-old Iranian woman presented to our hospital with epigastric abdominal pain of 2 hours' duration after the accidental ingestion of a dental prosthesis 2 days before admission. The patient had severe epigastric tenderness. Radiographic examination revealed nothing. Upper gastrointestinal endoscopy showed a swallowed lodged denture in the second to third parts of the duodenum, and the attempt to extract the denture failed. The patient underwent laparotomy and duodenal kocherization, pushing the denture to the stomach, and gastrostomy, and the denture was brought out without any complications.

CONCLUSIONS

Patients with old and worn dentures should have their prosthesis reconstructed and redesigned periodically in order to prevent denture ingestion and its complications. Early surgical intervention is recommended in patients with failed endoscopic extraction of foreign bodies and in those with duodenal perforation.

An Ingested Orthodontic Wire Fragment: A Case Report

Accidental ingestion or inhalation of foreign bodies has been widely documented, including incidents which occur whilst undertaking dental treatment. Most ingested objects pass through the gastrointestinal tract (GIT) spontaneously, but approximately 10%-20% need to be removed endoscopically and 1% require surgery. This case reports a complication arising from the accidental loss of an archwire fragment during maxillary archwire placement. It describes the immediate and subsequent management, including the use of radiographs to track the passage of the fragment through the gastro-intestinal tract. This case stresses the vigilance that dentists must take to prevent inhalation or ingestion of foreign bodies and the consequences of time-delays when management decisions are needed.

Retrieving dental instruments through endoscopy: A literature review

Clinical accidents involving dental instruments and materials inside the oral cavity are reported in the medical literature. Specifically, ingestion and aspiration of foreign bodies have greater prevalence in the routine of medicine and dentistry. Despite being less harmful than aspirations, the accidental ingestion of dental instruments does not always culminate in favorable prognoses. Mostly, complex conditions require medical intervention through endoscopy or surgical approaches. The present research aims to review the literature pointing out the specialties of dentistry most involved with accidental ingestion of dental instruments, highlighting the important role of endoscopy for accurately locating and retrieving foreign bodies. Prosthodontics, operative dentistry, orthodontics, and maxillofacial surgery arose as the specialties in which these accidents are more prevalent. Based on that, general dentists and specialists must be aware for the essential care to avoid such clinical accidents, as well as to know the available tools, such as endoscopy, to overcome these situations in the routine of dentistry.

Inhalation or ingestion of orthodontic objects in Finland

OBJECTIVES

Although inhalation or ingestion of orthodontic appliances can lead to serious medical problems, the real incidence of these complications is anecdotal. This study had two aims: (1) to define the frequency of accidental inhalation/ingestion of orthodontic objects in Finland and (2) to analyze their further management.

MATERIALS AND METHODS

An electronic, semi-structured questionnaire was sent to all members of the Orthodontic Section of Apollonia, the Finnish Dental Society (n=251) and the Finnish Federation of Dental Hygienists (n=437). After one reminder, 55.8% of dentists and 34.8% of dental hygienists responded.

RESULTS

In total, 20.0% of the dentists and 6.9% of the dental hygienists reported having one patient who had ingested or inhaled an orthodontic object. The percentages for two or more cases were 18.6% and 6.9%, respectively. According to dentists' answers, the procedures following these complications were (1) observation for 2-14 days (n=27), (2) radiologic evaluation (n=14), (3) medical emergency (n=6) and (4) dietary instruction (n=4). Dental hygienists reported (1) observation (n=9), (2) dietary instruction (n=3) and (3) medical emergency (n=1). None of the cases had been life-threatening.

CONCLUSIONS

Although the risk of inhalation or ingestion of orthodontic objects is small and the consequences rarely serious, it should be taken into consideration. Prospective patients should be informed of this possibility.

Management of accidental swallowing in implant dentistry

This report describes a protocol for managing the accidental swallowing of dental instruments in implant dentistry, illustrated by a patient who accidentally swallowed a hexagonal wrench. The first step was to refer the patient to the medical emergency hospital service for radiographic and clinical evaluation. The hexagonal wrench was located in the stomach and was immediately removed with an endoscopic procedure. The gastric mucosa was sampled via biopsy and the sample submitted to the urease test, which was positive for Helicobacter pylori. Triple treatment was instituted for gastritis caused by H pylori to avoid exposing the patient to unnecessary risk. Removal of a foreign body by means of an endoscopic procedure constitutes a safe and effective treatment.

Orthodontic Wire Ingestion during Treatment: Reporting a Case and Review the Management of Foreign Body Ingestion or Aspiration (Emergencies)

Today orthodontic treatment is in growing demand and is not limited to a specific age or social group. The nature of orthodontic treatment is such that the orthodontic wires and appliances, which are used to apply force and move the teeth, are exposed to the oral cavity. Shaping and replacing these wires in oral cavity are the major assignments of orthodontist on appointments. Therefore, we can say that orthodontic treatment requires working with dangerous tools in a sensitive place like oral cavity which is the entrance of respiratory and digestive systems. In this paper, a case of ingesting a broken orthodontic wire during eating is reported, and also necessary remedial measures at the time of encountering foreign body ingestion or aspiration are provided.

Laryngeal impaction of an archwire segment after accidental ingestion during orthodontic adjustment

Orthodontic archwires or fractured appliances that are accidentally swallowed can become lodged in the airway or gastrointestinal tract. Inadvertent ingestion or aspiration of an appliance or archwire piece during orthodontic appliance adjustment is a medical emergency with potentially serious complications, including possible death from asphyxiation. This article reports the accidental ingestion of a piece of orthodontic archwire that became impacted in the larynx; it was subsequently retrieved. Some potential complications are discussed, along with suggested precautions to prevent such mishaps when using fixed appliances.

A swallowed dental prosthesis causing duodenal obstruction in a patient with schizophrenia: Description of a new technique

INTRODUCTION

Foreign body ingestion has been a fundamental subject in the area of emergency surgery. The problem is encountered across all age groups; however, it is more common in the pediatric age group. Foreign body ingestion is rare in adults and usually occurs accidentally or in those with psychiatric problems, behavioral disorders, emotional disturbance, mental retardation, or impaired judgment caused by alcohol use.

PRESENTATION OF CASE

A 33-year-old Caucasian man with chronic schizophrenia was admitted to the emergency department with signs of upper gastrointestinal discomfort as a result of ingestion of a lower dental prosthesis. An abdominal X-ray showed the swallowed dental prosthesis in front of the vertebral column. A technique comprising gastrotomy and duodenal kocherization was used to remove the dental prosthesis; the prosthesis could not be removed endoscopically due to its fixed position on the duodenal wall.

DISCUSSION

Surgery of the duodenum is difficult and carries high mortality and morbidity. Therefore, endoscopy should be the first choice for patients in whom a foreign object is demonstrated to be fixed in the duodenum. In cases where endoscopic extraction fails, surgery should be considered. During surgery, foreign bodies should be removed, paying meticulous attention not to harm the integrity of the duodenum.

CONCLUSION

The technique presented in this study was performed successfully without any injury to the duodenum.
