Mechanisms of dental injuries in basketball, United States, 2003-2022

BACKGROUND/AIM

Oral injuries such as oral soft tissue lacerations and contusions can occur in basketball by mechanisms such as running into other players or falling. Given a high enough impact force, dental injuries such as tooth fractures and avulsions can occur. Previous research has studied the different types of oral injuries as well as the mechanisms that cause them. Yet, the mechanisms resulting in dental injuries have remained unexplored. The aims of this study were to investigate the distribution of different oral injuries within each injury mechanism and evaluate which mechanisms were most likely to lead to a dental injury.

MATERIALS AND METHODS

This is a retrospective cohort study using the National Electronic Injury Surveillance System (NEISS). Subjects who experienced oral injuries from basketball between January 1, 2003 and December 31, 2022 were included in this study. The independent variable was the injury mechanism. The dependent variable was the dental injury outcome (yes/no). Multivariate logistic regression was used to measure the association between the injury mechanism and the dental injury outcome. A p < .05 was considered statistically significant.

RESULTS

This study included 4419 subjects who experienced oral injuries (national estimate, 138,980). Approximately 14.7% of oral injuries were dental injuries. Subjects experiencing collisions with objects such as walls or the basketball hoop (odds ratio (OR), 4.39; p < .001), falls (OR, 3.35; p < .001), or contact with the basketball (OR, 1.77; p = .006) had significantly higher odds of sustaining a dental injury relative to those experiencing contact with another player.

CONCLUSIONS

Basketball players experiencing contact to the mouth have high odds of sustaining a dental injury. An understanding of injury mechanisms is important for medical teams to manage these injuries and for coaches to educate athletes on safe and proper playing styles. Furthermore, healthcare providers and basketball staff should encourage athletes to wear mouthguards to reduce the risk of traumatic dental injuries.

Child abuse and neglect: oral and dental signs and the role of the dentist

Historically, the law, dental and forensic literature has included numerous articles concerning abused children. The orofacial structures are injured frequently in the maltreated child. Injuries of the neck, head, face, and oral cavity represent the most affected areas of the victim's body that routinely sustain physical trauma in child maltreatment cases. This literature review aimed to report the state of art of child abuse from the point of view of the dentist with focus on studies in dental aspects of child abuse and neglect of the last ten years. Considering the time slot, 20 papers were included with the following inclusion criteria: papers published in English, all keywords included in the title, articles available on PubMed. Many of the injuries are within the scope of dentistry or easily observed by the dental professional during routine dental treatment, and it is essential that the dentist recognizes them. Concerning neglect, it is appropriate to make a distinction between deliberate parental behavior that has the consequence of unavoidable and voluntary neglect towards their children and those conditions of involuntary carelessness determined by socio-economic and cultural factors such as family isolation, lack of finances, parental ignorance, or lack of perceived value of oral health. Therefore, it is relevant that the dentist pays attention to the cases to report and those that only need help.

Evaluation of the In Vitro Oral Wound Healing Effects of Pomegranate (Punica granatum) Rind Extract and Punicalagin, in Combination with Zn (II)

Pomegranate (Punica granatum) is a well-established folklore medicine, demonstrating benefits in treating numerous conditions partly due to its antimicrobial and anti-inflammatory properties. Such desirable medicinal capabilities are attributed to a high hydrolysable tannin content, especially punicalagin. However, few studies have evaluated the abilities of pomegranate to promote oral healing, during situations such as periodontal disease or trauma. Therefore, this study evaluated the antioxidant and in vitro gingival wound healing effects of pomegranate rind extract (PRE) and punicalagin, alone and in combination with Zn (II). In vitro antioxidant activities were studied using DPPH and ABTS assays, with total PRE phenolic content measured by Folin-Ciocalteu assay. PRE, punicalagin and Zn (II) combination effects on human gingival fibroblast viability/proliferation and migration were investigated by MTT assay and scratch wounds, respectively. Punicalagin demonstrated superior antioxidant capacities to PRE, although Zn (II) exerted no additional influences. PRE, punicalagin and Zn (II) reduced gingival fibroblast viability and migration at high concentrations, but retained viability at lower concentrations without Zn (II). Fibroblast speed and distance travelled during migration were also enhanced by punicalagin with Zn (II) at low concentrations. Therefore, punicalagin in combination with Zn (II) may promote certain anti-inflammatory and fibroblast responses to aid oral healing.

Sclerotherapy of Vascular Malformations in the Oral Cavity-Minimizing Postoperative Morbidity

Vascular malformations (VMs) are a wide vascular or lymphatic group of lesions common on the head and neck. The objective of this study was to assess the efficacy and morbidity of sclerotherapy for the treatment of VMs in the oral and perioral area. Special attention was given to factors that may contribute to minimizing postoperative morbidity. Data from 25 patients (32 lesions) with oral VMs submitted to sclerotherapy with monoethanolamine oleate (EAO) were included. A structured form was used to collect data. An arbitrary score was determined to evaluate postoperative morbidity. Each of the following signs or symptoms received one point: pain, swelling, hematoma, ulceration, erythema, transient numbness, and transient itching. Pain and swelling were further divided into mild to moderate (1 point) and severe (2 points). Theoretically, the score was in the range of 0–9. Calculated scores ranged 0–4. The patients were further divided into two groups with scores of 0–1 denoting minimal morbidity (MIN) and 2–4 denoting significant morbidity (SIG). The number of lesions in each morbidity-score group were comparable (MIN 17and SIG 15). There were no statistically significant differences between the groups regarding age, number of applications, or average injection volume per mm lesion. Statistically significant differences were noted regarding gender (p = 0.05), lesion diameter (p = 0.030), total volume of first (p = 0.007) and second application (p = 0.05), and total injected volume (p = 0.03). Factors contributing to the risk for significant morbidity included being male, lesion diameter > 5 mm, volume > 0.3 mL per application, and total injected volume > 0.3 mL. A waiting time of 12 weeks prior to additional EAO application was required in 12 out of 29 lesions for clinical observation of complete regression. It was concluded that sclerotherapy with EAO as monotherapy is easy to apply, safe, and effective within a small number of sessions. Application of <0.3 mL EAO per session, and a waiting time of 12 weeks prior to the second application, would significantly minimize morbidity.

Mouthguards for the Prevention of Orofacial Injuries in Military and Sports Activities: Part 1: History of Mouthguard Use

This is the first of a two-part series on the history and effectiveness of mouthguards (MGs) for orofacial injury protection. Military studies have shown that approximately 60% of orofacial injuries are associated with military training activities and 20% to 30% with sports. MGs are hypothesized to reduce orofacial injuries by separating the upper and lower dentation, preventing tooth fractures, redistributing and absorbing the force of direct blows to the mouth, and separating teeth from soft tissue, preventing lacerations and bruises. In 1975, CPT Leonard Barber was the first to advocate MGs for military sports activities. In 1998, Army health promotion campaigns promoted MG education and fabrication. A US Army basic training study in 2000-2003 showed that more MG use could reduce orofacial injuries and the Army Training and Doctrine Command subsequently required that basic trainees be issued and use MGs. Army Regulation 600-63 currently directs commanders to enforce MG use during training and sports activities that could involve orofacial injuries. In the civilian sector, MGs were first used by boxers and then were required for football. MGs are currently required nationally for high school and college football, field hockey, ice hockey, and lacrosse, and are recommended for 29 sport and exercise activities.

Mouthguards for the Prevention of Orofacial Injuries in Military and Sports Activities: Part 2, Effectiveness of Mouthguard for Protection From Orofacial Injuries

This is second of a two-part series on the history and effectiveness of mouthguards (MGs) for protection from orofacial injuries. MGs are hypothesized to reduce orofacial injuries by separating the upper and lower dentation, preventing tooth fractures, redistributing and absorbing the force of direct blows to the mouth, and separating teeth from soft tissue which helps prevent lacerations and bruises. The single study on MG use in military training found that when boil-and-bite MGs were required for four training activities, orofacial injury rates were reduced 56% compared with when MGs were required for just one training activity. A recent systematic review on the effectiveness of MGs for prevention of orofacial injuries included 23 studies involving MG users and nonusers and a wide variety of sports. For cohort studies that directly collected injury data, the risk of an orofacial injury was 2.33 times higher among MG nonusers (95% confidence interval, 1.59-3.44). More well-designed studies are needed on the effectiveness of MGs during military training. Despite some methodological limitations, the current data suggest that MGs can substantially reduce the risk of orofacial injuries in sport activities. MGs should be used in activities where there is a significant risk of orofacial injuries.

Oral injuries in children less than 24 months of age in a pediatric emergency department

BACKGROUND

Oral injuries in young children may indicate physical abuse. The prevalence of oral injuries in young children presenting to the emergency department is unknown. These data would assist providers in making decisions about the need for further abuse evaluation.

OBJECTIVE

To determine the prevalence of oral injuries, associated chief complaints and characteristics, and frequency of abuse evaluations in children younger than 24 months presenting to a pediatric emergency department (PED).

PARTICIPANTS AND SETTING

Twelve pediatric emergency medicine physicians consecutively enrolled children younger than 24 months in a tertiary care PED.

METHODS

We performed a prospective observational study. Enrolled patients underwent a complete oral examination. Providers recorded patient demographics, type of chief complaint, oral injury details, developmental ability, and the presence of an abuse evaluation.

RESULTS

Oral injuries occurred in 36/1303 (2.8%, 95% CI 1.9-3.8%) and were more common in patients with traumatic (26/200, 13%) versus medical chief complaints (10/1,103, 0.9%) (p < .001). Of patients with oral injuries (36), 78% were mobile and 72% had traumatic chief complaints. Nine (25%) children with oral injuries were evaluated for abuse. Oral injuries in children 0-11 months old were more likely to be evaluated for abuse than children 12-24 months old (70.0% vs. 7.7%, p < .001).

CONCLUSIONS

The prevalence of oral injuries in children <24 months old presenting to a PED was low. Most occurred in mobile children and in children with traumatic chief complaints. Younger, non-mobile children with oral injuries had a higher likelihood of having an abuse evaluation.

Patterns of Oral-Maxillofacial Trauma and Determinant Factors among Brazilian Victims of Physical Aggression: A 4-Year Study

PURPOSE

To determine the prevalence of oral-maxillofacial trauma among Brazilian victims of physical aggression and identify its associated factors from a medico-legal and forensic perspective.

MATERIALS AND METHODS

A cross-sectional study was carried out involving the analysis of complete medico-legal and social reports of 3668 victims of physical aggression treated at a centre of legal medicine and forensic dentistry over the course of four years. The dependent variable was the occurrence of oral-maxillofacial trauma. The independent variables were sociodemographic status and characteristics of physical aggression. Statistical analyses included the chi-squared test (p < 0.05) as well as univariate and multivariate logistic regression analyses.

RESULTS

Oral-maxillofacial trauma occurred in 1655 cases (45.1%). Individuals who lived in suburban areas (OR = 1.32; 95%CI = 1.11-1.58) and those who were victims of community violence (OR = 1.20; 95%CI = 1.03-1.40) perpetrated by someone known to them (OR = 1.24; 95%CI = 1.03-1.40) using physical force (OR = 2.31; 95%CI = 1.96-2.72) on weekends (OR = 1.19; 95%CI = 1.04-1.37) and during nighttime hours (OR = 1.23; 95%CI = 1.08-1.41) were more likely to exhibit oral-maxillofacial trauma.

CONCLUSION

The prevalence of oral-maxillofacial trauma was high and the associated factors were area of residence, type of violence, type of offender, mechanism of violence, day, and period of occurrence.

A Proposed Method for Covering a Mini-Screw Head While Maintaining Space for Ligation

The use of mini-screws, also known as temporary anchorage devices (TADs), to obtain absolute anchorage has become very popular in orthodontics. Nevertheless, potential complications, including traumatic soft tissue lesions, accompany their use. We propose a method to cover the mini-screw head to prevent traumatic soft tissue lesions and promote patient comfort, while maintaining some separation between the composite resin and the peri-implant tissue.

[Effect of rhEGF on the levels of serum EGF and inflammatory cytokines in patients with oral and maxillofacial trauma]

PURPOSE

To investigate the effect of debridement combined with recombinant human epidermal growth factor (rhEGF) on wound healing, scar formation, serum epidermal growth factor and inflammatory factors in patients with oral and maxillofacial trauma.

METHODS

Eight-two cases with oral and maxillofacial trauma treated in our hospital (January 2015 to December 2016) were retrospectively analyzed. All patients received routine treatment, 41 received rhEGF besides routine treatment (experimental group), 41 patients received only cosmetic debridement and suturing (control group). The effect, wound healing time of 2 groups were recorded and compared. The serum epidermal growth factor, interleukin -6 (IL-6), tumor necrosis factor alpha (TNF-α) and interleukin -1 (Interleukin-1, IL-1) before and after operation were compared between 2 groups. SPSS16.0 software package was used to analyze the data.

RESULTS

The average wound healing time of the patients in the experimental group was 5.1±1.3 days, and the average wound healing time of patients in the control group was 7.4±1.9 days, the difference between 2 groups was statistically significant (t=6.397, P<0.01). The effective rate of the experimental group was significantly higher than the control group (P<0.05). Before operation, the serum epidermal growth factor, IL-6, TNF-α and IL-1 in 2 groups had no significant differences (P>0.05); 2 days and 5 days after operation, the serum epidermal growth factor level of the experimental group was significantly higher than the control group(P<0.05). The serum IL-6, TNF-α, IL-1 level of the experimental group were significantly lower than the control group(P<0.05).The side effects happened in the experimental group were significantly lower than control group (P<0.05).

CONCLUSIONS

Patients with oral and maxillofacial trauma treated by debridement combined with rhEGF can promote wound healing and reduce the degree of inflammation.

A treatment algorithm for the management of intraoral burns: A narrative review

Oral mucosa follows a distinctly different trajectory of wound healing than skin. Although there are contemporary guidelines regarding treatment of burns to the skin, there is no standard of care specific to intraoral burns. This narrative review proposes an evidence-based treatment algorithm for the management of intraoral burns. Data was collated through a comprehensive review of the literature and only included studies that have reported particular success with favorable short- and long-term prognoses. In order to critically appraise the strength of the treatment recommendations, the GRADE criteria was applied to each arm of the algorithm. The algorithm was initially subdivided into the four primary etiologies of intraoral burns - thermogenic, cryogenic, chemical, electrical. Our findings emphasize the importance of conservative modalities of intra-oral burn treatment.

Oral and Dental Aspects of Child Abuse and Neglect

In all 50 states, health care providers (including dentists) are mandated to report suspected cases of abuse and neglect to social service or law enforcement agencies. The purpose of this report is to review the oral and dental aspects of physical and sexual abuse and dental neglect in children and the role of pediatric care providers and dental providers in evaluating such conditions. This report addresses the evaluation of bite marks as well as perioral and intraoral injuries, infections, and diseases that may raise suspicion for child abuse or neglect. Oral health issues can also be associated with bullying and are commonly seen in human trafficking victims. Some medical providers may receive less education pertaining to oral health and dental injury and disease and may not detect the mouth and gum findings that are related to abuse or neglect as readily as they detect those involving other areas of the body. Therefore, pediatric care providers and dental providers are encouraged to collaborate to increase the prevention, detection, and treatment of these conditions in children.

Special Smiles: Sports Dentistry and the Special Needs Athlete

There is a need to expand dental services to underserved populations, such as athletes with intellectual and developmental disabilities. This review introduces dentists to this need by sharing the direction taken by the Special Smiles program of Special Olympics and addressing the need to educate special needs athletes on prevention and care of sports-related mouth injuries.

The Role of Mouthguards in Preventing and Reducing Sports-related Trauma

a mouthguard, also known as a gumshield, mouth protector or sports guard is an appliance that covers the teeth and surrounding mucosa with the aim of preventing or reducing trauma to the teeth, gingival tissue, lips and jaws. The device is usually worn on the maxillary arch and works by separating the maxillary and mandibular dentition, protecting the teeth from the surrounding soft tissue, absorbing or redistributing shock and/or stabilising the mandible during traumatic jaw closure. They may also play a role in preventing and reducing concussion by absorbing impact forces that would otherwise be transmitted through the base of the skull to the brain, although the evidence for this is less conclusive. A mouthguard will usually fall into one of three categories: stock mouthguards (which are made ready to use and are believed to give the least protection), the mouth-formed or 'boil and bite' type (which are heated in hot water, placed in the mouth and moulded to the teeth) and custom-made mouthguards (which are usually made on a stone model of the maxillary teeth and surrounding tissue and are thought to give the most protection). These devices can be made from various materials but ethylene-vinyl acetate is by far the most popular material, probably because of the ease with which it can be used for the production of custom-made mouthguards. This paper gives a review of the role of mouthguards in preventing and reducing sports-related trauma and examines the materials that are used to fabricate them.

Inter-rater reliability of the Reaper Oral Mucosa Pressure Injury Scale (ROMPIS): A novel scale for the assessment of the severity of pressure injuries to the mouth and oral mucosa

BACKGROUND

Patients who are intubated in the ICU are at risk of developing pressure injuries to the mouth and lips from endotracheal tubes. Clear documentation is important for pressure wound care; however, no validated instruments currently exist for the staging of pressure injuries to the oral mucosa. Instruments designed for the assessment of pressure injuries to other bodily regions are anatomically unsuited to the lips and mouth.

OBJECTIVES

This study aimed to develop and then assess the reliability of a novel scale for the assessment of pressure injuries to the mouth and oral mucosa.

METHODS

The Reaper Oral Mucosa Pressure Injury Scale (ROMPIS) was developed in consultation with ICU nurses, clinical nurse educators, Intensivists, and experts in pressure wound management. ICU nurses and portfolio-holders in pressure wound care from Peninsula Health (Victoria, Australia) were invited to use the ROMPIS to stage 19 de-identified clinical photographs of oral pressure injuries via secure online survey. Inter-rater reliability (IRR) was calculated using Krippendorff's alpha (α).

RESULTS

Among ICU nurses (n=52), IRR of the ROMPIS was α=0.307; improving to α=0.463 when considering only responses where injuries were deemed to be stageable using the ROMPIS (i.e. excluding responses where respondents considered an injury to be unstageable). Among a cohort of experts in pressure wound care (n=8), IRR was α=0.306; or α=0.443 excluding responses indicating that wounds were unstageable.

CONCLUSIONS

An instrument for the assessment and monitoring of pressure injuries to the mouth and lips has practical implications for patient care. This preliminary study indicates that the ROMPIS instrument has potential to be used clinically for this purpose; however, the performance of this scale may be somewhat reliant on the confidence or experience of the ICU nurse utilising it. Further validation is required.

[The influence of military underwater activity on the oral cavity]

The military dentists who serve in the navy, treat divers, among other patients. Divers are being exposed to a changing, unique environment on a regular basis. The aim of this article is to review latest literature on the different effects of scuba diving on the diver's head, face and oral regions and to emphasize methods of disease prevention, diagnostic tools and treatment guidelines. The review focuses on diving barotrauma (pressure- induced injury related to an air space) as well as scuba diving mouthpiece-related oral conditions, which include facial, jaw pain and headaches, decompression sickness and mouthpiece-related herpes infection. Each condition is described by its effect on the oral cavity and in particular the teeth.

Behaviour Management of Children Presenting in the Emergency Department with OMFS Problems

INTRODUCTION

This paper is a summary of three case reports of patients treated by Oral and Maxillofacial (OMFS) Dental Foundation Trainees (DF2s) at a busy London paediatric Accident and Emergency (A&E) department.

DISCUSSION

Behavioural management for paediatric patients is challenging. The authors discuss various non-pharmacological behavioural management methods as stand-alone techniques or as an adjunct to drugs (sedation or anaesthesia). They highlight three cases where a dedicated Play-Specialist is employed to assist treatment undertaken in an acute hospital setting. Here we discuss options available to clinicians for behaviour management as well as three case scenarios detailing the use of Play-Specialists alongside conventional pharmacological and non-pharmacological methods.

CONCLUSION

Through implementing appropriate behavioural management methods (with or without drugs), optimal patient care can be achieved. The benefit of having a specialist solely trained in engaging with children, with respect to their behavioural tendencies, is demonstrated, highlighting their value in an acute setting.

[Comparison of two shaping methods for double-lumen endotracheal tube intubation by Shikani optical stylet laryngoscope]

OBJECTIVE

To compare the efficacy and safety of two different shaping methods for double-lumen endotracheal tube (DLT).DLT was shaped with the rod of a Shikani optical stylet (SOS) with the tracheal orifice aligned with the convex aspect of the distal curvature or the concave aspect of the distal curvature.

METHODS

Patients scheduled for elective thoracic surgery and required intubation with a left-sided DLT were enrolled in this study. They were randomized into two groups. They were intubated with a DLT, which was shaped with the rod of a SOS with its tracheal orifice aligned with the convex aspect of the distal curvature (group T) or the concave aspect of the distal curvature (group U). Time for SOS manipulation, intubation attempts, intubation resistance score, malposition of bronchial intubation, time for fiberoptic bronchoscope (FOB) identification of bronchial placement, total intubation time and oral mucosal or dental injury were recorded. Hoarseness and throat sore of the patients were evaluated 1 hour and 24 hours after surgery.

RESULTS

A total of 136 patients completed the study, with 68 in each group. Time for SOS manipulation was significantly shorter in group U [(35.1±6.1) s vs. 39.6±11.8) s, P=0.007]. First attempt success rate did not differ between the groups (92.6% vs.88.2%, P=0.561). Intubation resistance score was significantly lower in group U. Group T had fewer patients who suffered malposition of bronchial intubation than group U (4 vs.13, P=0.020) and cost less time for FOB identification of bronchial placement [(44.1±20.9) s vs.(53.6±29.2) s, P=0.032]. Total intubation time and the incidence of oral mucosal or dental injury did not differ between the groups. The severity and incidence of hoarseness were lower in group U than in group T 1 hour after surgery. The severity and incidence of sore throat were lower in group U than in group T 1 hour and 24 hours postoperatively.

CONCLUSION

When lacing a left-sided DLT using a SOS, shaping the DLT with the tracheal orifice aligned with the concave aspect of the distal curvature saves SOS manipulation time, decreases the severity and incidence of postoperative hoarseness and sore throat. However, this modified shaping method increases the incidence of malposition of bronchial intubation and time for FOB identification of bronchial placement.

Unusual planned complex suicide committed with a muzzle-loading pistol in combination with subsequent hanging

In Germany, suicides by firearms are not very common in contrast to deaths by hanging and intoxications. The use of historical muzzle-loading firearms in the context of suicides is a rarity. Contact shots from muzzle loaders cause an unusual wound morphology with extensive soot soiling. We report the case of a 59-year-old man, who committed a planned complex suicide by shooting into his mouth with a replica percussion gun in combination with hanging. The gunshot injury showed strong explosive effects in the oral cavity with fractures of the facial bones and the skull associated with cerebral evisceration (so-called Krönlein shot). Due to the special constellation of the case with hanging immediately after the shot, external bleeding from the head injuries was only moderate. Therefore, the head injuries could be assessed and partially reconstructed already at the scene.

Guideline on Oral and Dental Aspects of Child Abuse and Neglect

In all 50 states, physicians and dentists are required to report suspected cases of abuse and neglect to social service or law enforcement agencies. The purpose of this report is to review the oral and dental aspects of physical and sexual abuse and dental neglect and the role of physicians and dentists in evaluating such conditions. This report addresses the evaluation of bite marks as well as perioral and intraoral injuries, infections, and diseases that may be suspicious for child abuse or neglect. Physicians receive minimal training in oral health and dental injury and disease and, thus, may not detect dental aspects of abuse or neglect as readily as they do child abuse and neglect involving other areas of the body. Therefore, physicians and dentists are encouraged to collaborate to increase the prevention, detection, and treatment of these conditions.

A novel mouthpiece prevents bite injuries caused by intraoperative transcranial electric motor-evoked potential monitoring

PURPOSE

Intraoperative transcranial motor-evoked potential monitoring causes contraction of the masseter muscles, which may cause injuries to the oral cavity and damage to the orotracheal tube. We developed a mouthpiece made from vinyl-silicone impression material to prevent these injuries. The purpose of this study was to examine its efficacy and safety.

METHODS

Twenty-two patients undergoing spinal surgery under transcranial motor-evoked potential monitoring were fitted with bespoke vinyl-silicone mouthpieces by dentists before surgery. On induction of general anesthesia and orotracheal intubation, the mouthpiece was attached to the upper and lower dental arches. A lateral cervical X-ray was taken at the end of surgery to examine the condition of the orotracheal tube. The incidence of endotracheal tube deformation was compared with an historic control group of 20 patients in whom a conventional gauze bite block had been previously used before induction of the mouthpiece. The oral cavity was examined by a dentist the day before surgery and 3 days postoperatively, and intraoral injuries were recorded.

RESULTS

No endotracheal tube deformation was found in 22 patients fitted with the new mouthpiece. The incidence of tube deformation (none of 22 patients, 0 %) was significantly lower than in those who had been fitted with the gauze bite block (9 of 20 patients, 45.0 %; p < 0.001). Application of the mouthpiece resulted in no tongue or tooth injuries.

CONCLUSION

A novel mouthpiece reduced the incidence of damage to the endotracheal tube caused by intraoperative transcranial motor-evoked potential monitoring.

Retrospective review of 78 rehabilitated head and neck postoncological patients: a new classification method

BACKGROUND

Numerous studies have been published about the prosthetic rehabilitation of the postoncological maxillo-facial patient, but the guidelines that emerge lack a correlation between the anatomical classification of the treated site, which generally is preparatory upon surgery, and the type of prosthetic rehabilitation appropriate to the new anatomical and functional condition. With this correlation, it would be possible to obtain a multidisciplinary and predictable therapeutic process, able to identify from the beginning the best type of prosthetic rehabilitation.

METHODS

The authors analyzed a sample of 78 patients treated in the Maxillofacial Surgery Unit of "Sapienza" University of Rome for a tumor of the head and neck area, and at a later stage prosthetically rehabilitated in the years from 2010 to 2013 in the Prosthetic Rehabilitation Unit of the same University because of the consequences of the ablative surgery. After having analyzed data concerning the treatment of the maxillofacial tumor, Authors classified the kind of prosthetic rehabilitation. Removable prosthesis was chosen in 18 cases, while implant (or teeth)-supported rehabilitation was performed in 60 cases.

RESULTS

Authors correlated the kind of surgical reconstruction to the prosthetic rehabilitation performed. In the maxilla removable prosthesis was chosen in 8 cases, while implant supported rehabilitation was performed in 18 cases. In the mandible 10 cases were rehabilitated through a removable prosthesis and 42 through a teeth or implant supported prosthesis.

CONCLUSIONS

It is evident the need to perform a careful evaluation of the patient, in order to identify the best possible prosthetic rehabilitation.

Oral Exposure of a Child to a Lithium Ion Battery

Battery exposure has the potential for severe morbidity and possible mortality. Accidental exposure is rising with the increased use of button batteries, and young children and older adults are at highest risk for accidental exposure. The purpose of this paper is to report a case of mouth exposure to a lithium ion battery in a boy. A review of the current literature on incidence, diagnosis, and outcomes of battery exposure is presented. When symptoms such as diarrhea, vomiting, and abdominal distress of non-specific origin are present, battery ingestion should be included in the differential diagnosis. Dentists may be the first health professionals to encounter battery exposure, especially in the case of mouth exposures. Knowledge of signs and symptoms are necessary to properly diagnose and refer for medical management.

[Awake Nasotracheal Intubation for a 4-Year-old Boy with an Oral Penetrating Toothbrush Injury]

We report a case of an oral penetrating injury caused by a toothbrush in a 4-year-old 17-kg boy. The toothbrush was lodged in the right cervical region through the oral cavity, and emergency surgery for removal was planned under general anesthesia. Although mask ventilation was not possible because of the protruding toothbrush handle, awake nasotracheal intubation was successfully performed with a fiber-scope and intravenous fentanyl 25 μg. We conclude that appropriate analgesics could facilitate awake intubation in pediatric patients.

Mouth in Foot Disease

Toothpicks are commonly used household items that rarely cause serious injury or infection. Toothpick-related injuries often occur due to ingestion with subsequent trauma/infection at distal sites within the gastrointestinal tract; however, cardiovascular, pleural, and soft tissue infections have been reported. Eikenella corrodens is a gram-negative, facultative anaerobic bacillus found in oral flora associated with bite wound infections. A few case reports describe E. corrodens osteomyelitis from toothpick puncture wounds. We report a case of foot cellulitis and abscess in an elderly diabetic after toothpick puncture injury that was unresponsive to empiric antibiotics. Wound cultures grew E. corrodens and rare Peptostreptococcus species. E. corrodens is resistant to first-generation cephalosporins, macrolides, aminoglycosides, clindamycin, and metronidazole. This case highlights the insidious nature of E. corrodens infections and the need to tailor empiric antibiotics for skin and soft tissue infections based on the mechanism of injury. In addition, this case stresses the importance of protective footwear in diabetics and serves as a cautionary tale regarding the use of seemingly innocuous toothpicks.

Prevalence of Oral and Maxillofacial Trauma in Elders Admitted to a Reference Hospital in Northeastern Brazil

OBJECTIVE

To know the prevalence and etiology of oral and maxillofacial trauma in elders.

METHODS

Analytical quantitative cross-sectional study conducted at a public trauma hospital located in Fortaleza-Ceará, Brazil. The study population comprised patients with trauma who were hospitalized from April to August 2014. Of these patients, patients with oral and maxillofacial trauma were chosen to be included in the research. A questionnaire was administered in order to obtain information on socio-demographics, systemic comorbidities, use of medication, deleterious habits (smoking and alcohol consumption), etiology of oral and maxillofacial trauma and type of pre-hospital care.

RESULTS

Of the 280 elderly hospitalized with trauma, 47 had oral and maxillofacial trauma, with a prevalence of 16.8%. In this group, the age ranged from 60 to 88 years, with a mean age of 72.4 years (SD± 8.38). The elderly were mostly women (55.3%), self-declared pardos (53.2%), who presented with cardiovascular disorders (48.9%), and who received formal pre-hospital care (70.2%). Elderly who were in the 60-69 years age group, spent 6-9 years at school and drank alcohol were 2.64, 3.75, and 1.97, respectively, more likely to suffer oral and maxillofacial trauma. The main causes of trauma were physical aggression, traffic accidents, falls and domestic accidents. All of the physical aggressions resulted in oral and maxillofacial traumas, and the elderly who suffered traffic accidents were four times more likely to have oral and maxillofacial trauma.

CONCLUSION

The prevalence of 16.8% and the lack of research on oral and maxillofacial traumas in the elderly is worrisome and should be included in the oral health indicators for the elderly population to support the importance of oral health.

Prevalence and prevention of dental injuries in young taekwondo athletes in Croatia

AIM

The aim of this study was to evaluate the occurrence of dental and facial injuries, the habit of wearing mouthguard and the awareness regarding injury prevention and first aid after tooth avulsion among young taekwondo athletes in Croatia.

MATERIALS AND METHODS

A survey on a sample of 484 taekwondo athletes was conducted, which included 271 male (56%) and 213 female (44%) athletes aged between 8 and 28 years. The questionnaire submitted to the athletes contained 15 questions about dental trauma, use of mouthguard, dental trauma prevention, level of awareness about tooth avulsion and replantation and disturbances associated with mouthguard use. Collected data were evaluated according to gender, age groups and duration of actively engagement in taekwondo. Descriptive statistics and Chi-square tests were used for comparisons between groups.

RESULTS

From the survey 300 (62%) of 484 athletes had sustained one serious injury and 103 (21%) had sustained an orofacial injury, while 194 (40%) had observed another player sustaining a dental injury. Higher number of orofacial injuries was observed in males (24%) than in females (18%). Furthermore, 98 (20%) athletes have experienced one or more dental injuries, and out of these 98 suffering dental injury 60 were male (61%) and 38 were female (39%). The frequency of orofacial injuries in the older group (42%) is higher than in three younger groups (younger cadets 25%; cadets 13%; juniors 20%) (p<0.05). Mouthguard wearing was recorded in 465 athletes (96%), 47.1% of them wear stock mouthguard, 47.6% wear boil and bite mouthguard, but only 5.3% were custom-made mouthguards. Most of them (96%) consider that mouthguards are useful for injury prevention in taekwondo.

CONCLUSION

The results of this survey show that dental and orofacial injuries occur in taekwondo in all age groups but mostly in the senior group. Taekwondo players know the importance of mouthguard use, but only 5% use custom made mouthguards. This is not adequate for dental injury prevention and highlights the important role of dental professional in education of athletes for advocating the use of custom made mouthguards.

Graduating dental students' views of competency statements: importance, confidence, and time trends from 2008 to 2012

Competency documents are used in dental education as both an educational framework and an accreditation instrument. The aim of this study was to analyze the perceptions of graduating dental students at the University of British Columbia (UBC) regarding the importance of each competency statement, as well as to assess their confidence in their abilities associated with each statement. The instrument was based on the survey developed by Schönwetter et al. at the University of Manitoba using the Association of Canadian Faculties of Dentistry competency document. The current study surveyed UBC graduating students in the years 2008 through 2012. The response rates ranged from 66.7% to 95.9%, averaging 77.5% across all five years. The results showed that, overall, the students rated all the competencies as important, but they rated their confidence lower than the perceived importance. Correlation coefficients averaged a moderate correlation of 0.376 for all competency statements except the five with the greatest discrepancy between perceived importance and confidence. The competencies the students perceived as most important tended to be associated with tasks frequently performed during predoctoral dental education. The instrument used in this study can help other academic dental institutions identify patterns of students' perceived competency importance and confidence to inform allocation of teaching time and resources and adopt new methodologies to address identified areas of need.

Multidisciplinary care in severe pediatric electrical oral burn

Oral burns in pediatric patient are commonly due to electrical injuries, representing an important reconstructive issue even for functional than esthetic reason. Different classification, surgical management and even oral device were described to allow the best long-term result. In most case a multidisciplinary approach is necessary to achieve a satisfactory outcome. A severe case of pediatric oral burn with germinative teeth damage is presented, describing a multispecialist team approach that guarantee a satisfactory outcome by reconstructive surgery, careful progressive evaluation of dental and soft tissue healing and speech recovery. The use of acellular dermal substitute template within traditional reconstructive surgery had provided a good functional and esthetic result joint to valid preservation of germinative dental element as shown at long-term X-ray evaluation. Intensive rehabilitation speech program has also avoided phonetic impairment in an important speech develop period. It was so evident that the necessity of a multispecialist care in such difficult injury to achieve the best long-term result.

[Frostbite injuries causing compromised airway after inhalation of propane]

We describe a case report of a 23-year-old man with acute pharyngeal injuries due to frostbite subsequent to inhalation of propane. He was fiber-optically intubated on admission to hospital since his airways were considered acutely compromised. He was subsequently kept intubated for 11 days due to persistent pharyngeal oedema and frostbite injuries. The latter is caused by low temperature of propane upon release from a pressurized container. Injuries caused by frostbite often gradually progress and thus caution should be exerted in regards to airway management.

Group A beta streptococcal infections in children after oral or dental trauma: a case series of 5 patients

Group A streptococcus (GAS) produces a variety of disease processes in children. Severe invasive diseases such as necrotizing fasciitis can result. Traumatic dental injuries are common in the pediatric population, although the role of dental injuries in invasive GAS disease is not well characterized. In this article, we describe our retrospective series of 5 cases of GAS infection following oral or dental trauma in children.

Is it safe to use a toothbrush?

AIM

To systemically collect and summarize the literature on case reports concerning adverse events associated with the oral use of a toothbrush.

MATERIALS AND METHODS

Two electronic databases were searched for articles published up to October 2013 to identify appropriate studies using focused search terms and 'case reports' as a filter. Results. A comprehensive search identified 419 unique titles and abstracts. Ninety-four studies met the eligibility criteria. In total, 118 subjects (age range = 1-60 years) presented adverse events related to the oral use of a toothbrush. Events could be summarized in five categories, of which ingestion was the most reported problem among the individuals (50 cases). This was followed by impaction of a toothbrush (27 cases). Reports more frequently involved females and children were more likely to have injuries compared to males and adults. Most of the cases that presented with adverse events of the oral use of a toothbrush were referred for treatment to a physician.

CONCLUSIONS

The combined evidence related to serious adverse events as presented in case reports showed that the oral use of a toothbrush can be associated with ingestion, impaction, instant trauma, gingival traumatic injury and seizures. Given the incidence of reporting, important recommendations are that a toothbrush should not be used to induce vomiting, nor should people walk or run with this device in their mouths, especially children.

Prevalence of oral manifestations in soft tissues during early childhood in Brazilian children

This study aimed at assessing the prevalence of soft tissue oral manifestations in children during early childhood, according to age group, gender, and site in the oral cavity, and at correlating these oral manifestations with systemic alterations. A cross-sectional study was conducted involving 586 children from 0 to 3 years of age (12.4 ± 11.8 months), 316 (53.9%) male and 270 (46.1%) female, in the city of Mauá, SP, Brazil. Examination was performed by a single examiner (Kappa Index = 0.90) according to World Health Organization criteria (WHO, 1997).The prevalence of oral manifestations in the soft tissues of children during early childhood was 34.8%. The age group showing statistical significance was 0-1 months old (56.4%). Epstein's pearls were significantly present (43.2%) in 0-1-month-old babies, and gingivitis in 12-24-month-olds (15.9%). The palate was the most affected region (16.7%). Infectious alterations were the most prevalent systemic alteration (20%). An association was observed between the presence of systemic alterations and the occurrence of oral manifestations. The prevalence of oral manifestations was 34.8%, regardless of gender, and was manifested mostly in 0-1-month-old babies. The palate was the most prevalent region, and the majority of oral manifestations were associated with systemic alterations.

[The influence of barometric pressure changes in the oral cavity: dental barotrauma and barodontalgia]

Several oro-facial physiologic and pathologic phenomena affect individuals during flight or self-contained underwater breathing apparatus (SCUBA) diving. Physicians and dentists who treat aircrews and divers are occasionally challenged by those manifestations, though their uncommon appearance. This article reviews the two main barometric-related phenomena in the oral cavity: dental barotrauma and barodontalgia. Dental barotrauma includes all barometric-related dental mechanical phenomena. Tooth fracture or failure of dental restoration usually appears in a tooth with a leaking restoration or secondary caries lesion. In addition, changes in barometric pressure can cause a reduction in the retention of dental restoration and appliance. Barodontalgia is the oral pain which evoked during changes of the atmospheric pressure. This manifestation can be classified as a direct or non-direct pain. In most cases, the direct pain is caused by deterioration of pre-existed oral disease, whereas the source of the nondirect pain is an extra-oral facial barotrauma. These two barometric-related manifestations can cause a decrease in life quality and jeopardize the safety of flight or diving.

Recurrent bilateral periorbital and circumoral bruising due to vomiting

Periorbital ecchymosis is due to extravasations of blood into the periorbital skin and the subcutaneous tissues around the eyes. 'raccoon eyes' or 'panda sign' is a distinctive type of periorbital ecchymosis where the bruising is characterised by tarsal sparing. This sparing is due to an anatomical structure called the orbital septum, which limits the spread of the discolouration beyond the tarsal plate. Hence 'raccoon eyes' description should be limited to orbital ecchymosis due to basal skull fractures only. While the bilateral bruising due to direct trauma to the eyes, or non-traumatic medical conditions, can spread beyond the tarsal plate as in our case. The differential diagnosis varies from trivial benign conditions to serious life-threatening illnesses. We describe a case of recurrent bilateral periorbital ecchymosis and facial bruising due to vomiting.

Spring-loaded custom tray: an alternative technique for recording impressions in a patient with a restricted mouth opening

For patients with extensive head and neck injuries due to trauma and/or extensive surgical procedures, their ability to open the mouth is severely limited. Prosthodontic treatment of these patients often leads to compromised impressions and prostheses. When making an impression, a wide mouth opening is necessary to ensure both proper tray insertion and the correct alignment during border molding procedures. For patients with a restricted mouth opening, it may be necessary to modify the standard impression procedure to fabricate a prosthesis successfully. This article describes an alternative method for fabricating a custom impression tray for a complete denture in patients with limited mouth opening abilities.

Barodontalgias, dental and orofacial barotraumas: a survey in Swiss divers and caisson workers

Changing ambient pressure can lead to medical conditions in body cavities filled with air. Intraoral pain elicited by changes in pressure is referred to as barodontalgia. Dental barotraumas are defined as pressure-induced damages of teeth and restorations. The pathophysiologic background so far is not completely clear. The present study deals with dental and orofacial symptoms which can occur as a result of pressure variations. With the aid of cantonal administrations, diving associations, and tunnel construction firms, 520 pressure-exposed individuals (499 scuba/ professional divers, 21 caisson workers operating at excess pressure) were questioned regarding dental problems. A personal interview was conducted with affected individuals. Problems in the dental area were experienced by 15% of all respondents. Toothaches were suffered by 10.2% of the participants. Tooth injuries occurred in 6.3% of all interviewees (26 fractured amalgam restorations, 4 crown fractures, 3 losses of tooth fragments). A proportion of 11.3% among the respondents complained about temporomandibular joint problems or mucosal irritations (for example aphthae) related to the mouthpieces. Barotraumas outside the dental area were incurred by 31.9% of the divers. Of these, 69.9% concerned the ears and 65.6% occurred during the descent. Based on the results obtained from the survey and taking into account the current literature, recommendations for the prevention of barotraumas in divers and caisson workers were prepared. Diagnostic exclusion of dental pathologies and avoidance of retentive reconstruction materials are important factors for the prevention of barodontalgias and dental barotraumas.

Forensic odontological examinations of alleged torture victims at the University of Copenhagen 1997-2011

BACKGROUND

Clinical forensic examinations of alleged torture victims have been performed by forensic pathologists at the University of Copenhagen since 1995. In 13.2%/33 of these cases the examinations were supplemented by a forensic odontological clinical examination. In this study the forensic odontological cases from the years 1997-2011 are presented and discussed.

METHODS

This study includes 33 reports from alleged torture victims (4 females, 29 males) who have been examined by a forensic odontologist at the Copenhagen School of Dentistry in the years 1997-2011.The material available consisted of copies of medical forensic reports and the forensic odontological reports including x-rays. BACKGROUND data, anamnestic data and results of the forensic odontological clinical examinations were registered as well as the conclusion of the clinical examinations.

FINDINGS

The forensic odontological clinical examinations were complicated by the presence of unspecific injuries and various degrees of active oral pathology. In 27 of the cases it was concluded that the findings were consistent with the alleged torture, in six of the cases the findings were concluded to be highly consistent with the alleged torture.

Commonly used topical oral wound dressing materials in dental and surgical practice--a literature review

A small number of medicaments are used in oral and maxillofacial surgery to dress wounds, relieve pain, prevent infection and promote healing. While these materials are routinely used, their constituents, uses and effects on oral tissues are rarely discussed. This literature review provides an overview of the constituents, uses and effects of the common materials--oxidised regenerated cellulose, Whitehead's varnish, Carnoy's solution, bismuth iodoform paraffin paste (BIPP), zinc oxide eugenol (ZOE) and Alvogyl.

Mandibular degloving injury in an Arabian filly

A 6-month-old Arabian filly escaped its handler while being led and slipped on pavement. The referring veterinarian recognized severe, soft tissue damage to the filly's lower jaw and referred the filly to the Veterinary Teaching Hospital for surgical management.

Child abuse: concerns for oral health practitioners

Child abuse and neglect are prevalent issues that permeate all ethnic, cultural and socioeconomic segments of society. Parents of abused children frequently change physicians in order to prevent detection, but they are more likely to continue to visit the child's dentist. Most states recognize four major types of maltreatment: neglect; physical abuse; psychological maltreatment; and sexual abuse. The American Academy of Pediatric Dentistry defines dental neglect as "the willful failure of parent or guardian to seek and follow through with treatment necessary to ensure a level of oral health essential for adequate function and freedom from pain and infection." The oral health practitioner must uphold his or her legal and ethical responsibility if there is suspicion, record and report the incidence. It may help save a child from further abuse.
