Associations between child abuse and neglect, and dento-alveolar injuries in a Children's hospital population.

BACKGROUND/AIM: The purpose of this study was to identify social variables common to children with dento-alveolar trauma (DAT) and child abuse and neglect (CAN) in a large children's hospital population. METHODS: Emergency department data from an urban trauma Level 1 children's hospital were queried between December 02, 2017 and September 30, 2022 to identify children with both DAT and CAN. Patients with DAT and CAN were compared to DAT-only children in a case-control study design. Descriptive statistics were used to report characteristics of children in case and control groups. Chi-Squared and Fisher's exact tests were used to compare cases and controls. The level of significance was set at p ≤ .05. RESULTS: In total, 14 children who had DAT and CAN reported simultaneously comprised the case group. A total of 42 children with DAT-only, age/sex matched with cases, comprised the control group. Mean (SD) age of cases was 10.4 (±4) and controls was 10.1 (±3.9) years-old. Eight cases (57.1%) and 24 controls (57.1%) were female. No statistical differences (p = .05) were present for language, race, insurance coverage, parental custody, legal guardianship, and type of residence for cases versus controls. Five (35.7%) cases had a special need versus 4 (9.5%) controls and was statistically different (p = .03). Nine (64.3%) cases had behavioral problems versus 13 (31%) controls (p = .05). Cases were more likely to have facial injuries than controls (74.3 vs. 31%), however no significant differences were present for total number of injured teeth, head injury or neck injury between cases and controls. In half of cases, the perpetrator reported was the sibling. CONCLUSIONS: Demographics did not predict CAN in children with dental injuries. Sibling violence should be considered in suspected CAN children.

Characteristics, treatment outcomes and direct costs of tooth avulsion in children treated at a major hospital.

BACKGROUND/AIMS: Avulsion of a permanent tooth is one of the most severe traumatic dental injuries, comprising an estimated 0.5%-16% of all dental injuries. The aim of this study was to estimate the direct financial costs of tooth avulsion in children based on stage of root maturity and the occurrence of ankylosis and to report patients' characteristics and outcomes of treatment. MATERIALS AND METHODS: A retrospective review of the dental records of children ages 6-18 who sustained a permanent tooth avulsion from 2010 to 2020 was completed. Relative Value Units (RVUs) were used to calculate the estimated cost of dental trauma care over the 2-year post-injury period for five different scenarios of avulsed teeth based on the stage of root maturity, the occurrence of ankylosis and whether the tooth was replanted. RESULTS: There were 452 avulsed permanent teeth in 348 patients. Of those, 157 teeth were included in the cost analysis. Overall, the average direct dental cost of avulsion was 46.4 RVUs equal to $1619 USD based on the 2021 conversion rate ($34.89 per RVU). Direct costs ranged between 40 RVUs ($1396) and 52.8 RVUs ($1842) depending on the root maturation and ankylosis status or whether the tooth was replanted; however, ANOVA test did not show any statistically significant differences between the mean RVUs of different groups (p = .85). Patients returned 9.5 times on average over the 2-year study period for dental trauma care after avulsion. CONCLUSION: The average direct cost of tooth avulsion within the limits of this study was $1619 USD. On average, patients returned for 9.5 follow-up visits after the avulsion. The stage of root maturity, the occurrence of ankylosis and whether the tooth was replanted or not were not significantly associated with the direct cost of dental care.

A 3-Year retrospective study of traumatic dental Injuries to the primary dentition.

BACKGROUND/AIMS: Traumatic dental injuries (TDIs) in the primary dentition are a significant public health problem, which has been neglected worldwide. Despite its high prevalence, limited studies address this injury. The aim of this study was to determine the characteristics and treatment modalities of TDIs affecting primary teeth, along with accompanying medical co-morbidities and attendance at follow-up appointments. MATERIAL AND METHODS: This retrospective analysis included all TDIs affecting primary teeth from January 2014 to January 2017. Data abstraction included demographics, time lapse prior to arrival at hospital, trauma etiology, classification of TDIs, soft tissue and supporting bone injuries, medical co-morbidities, emergency treatment, follow-up appointments and prognosis. RESULTS: Records of 283 children with 536 traumatized primary teeth were reviewed. The median age was 2 years and the maxillary right central incisor (35.1%) was the most frequently injured tooth. Almost half the patients, 46.3%, sought treatment after 24 h. Periodontal tissue injuries (97.2%) predominated TDIs for which fall accidents (82.0%) were the most encountered cause. Most patients (177/283) had accompanying soft tissue/supporting bone injuries and 67.2% had multiple traumatized teeth. Seventy percent of the patients were examined only or were prescribed medication. Survival time following TDIs was unknown in 67.7% of traumatized teeth due to non-attendance at follow-up appointments. Most patients (55.1%) did not attend the follow-up appointments. CONCLUSIONS: TDIs occurred in the primary dentition with the predominance of periodontal tissue injuries. When TDI was the presenting problem to hospital, accompanying systemic injury was rare. Treatment modalities were mostly limited to examination or extraction. The follow-up appointments were poorly attended.

The Effects of Primary Canine Loss on Permanent Lower Dental Midline Stability.

Purpose: The purpose of this study was to compare changes in the lower dental midline position after premature unilateral loss of a primary mandibular canine with dental midline position after normal primary mandibular canine exfoliation. Methods: Dental casts were identified from growth studies at the University of Iowa and the University of Toronto. Two groups of dental casts were identified: (1) premature unilateral loss; and (2) normal asymmetric exfoliation of a single primary mandibular canine. The first set of casts displaying unilateral primary canine loss (time one) and the second set of casts displaying full permanent dentition (time two) were collected. The palatal rugae and palatal raphe were used to construct a median palatal plane (MPP). Dental midline position at each time point was measured from the MPP. Results: A total of 56 cases (15 premature, 41 normal) were identified. The mean lower dental midline changes from time one to time two for the premature and normal loss groups were 1.32±0.83 mm and 0.97±0.91 mm, respectively. This difference was not statistically significant regarding group (P=0.62), gender (P=0.91), or the interaction effect of group and gender (P=0.85). Conclusions: There was no significant difference in midline shift between the 15 individuals with premature unilateral primary canine loss and the 41 individuals with normal, asymmetric unilateral loss of a primary canine.

Parental Attitudes Toward Advanced Behavior Guidance Techniques Used in Pediatric Dentistry.

PURPOSE: To re-examine parental attitudes toward advanced behavior management techniques in pediatric dentistry and determine whether cost, urgency, and amount of treatment influence parental preferences. METHODS: Parents viewed previously validated videotaped clinical vignettes of four advanced behavior guidance techniques: (1) passive immobilization; (2) active immobilization; (3) general anesthesia; and (4) oral sedation. The study was conducted in a children's hospital dental clinic and a suburban private pediatric dentistry office. Parents rated overall acceptance of the techniques, and acceptance under specified conditions using an anchored visual analogue scale. RESULTS: One hundred five parents completed the survey; 55 from the children's hospital and 50 from private practice. Oral sedation was rated as the most acceptable technique, followed by general anesthesia, active immobilization, and passive immobilization. As urgency, convenience, and previous experience increased, parental acceptance of the technique increased. As cost of treatment increased, parental acceptance decreased. Ratings between the children's hospital group and private practice group differed, as did the demographic variables of insurance, income, and race. CONCLUSIONS: The hierarchy of parental acceptance of advanced behavior guidance techniques is changing with increasing approval of pharmacological management and decreasing approval of physical management. The health care delivery system, urgency, convenience, previous experience, and cost all influence parental acceptance.

Diagnosis of an unusual finding in the primary dentition: a case report.

Patients may present to the dental office with unusual findings that have no obvious etiology. The purpose of this paper is to report the case of a two-year old female patient who presented with a foreign body mimicking pathosis. Diagnosis and treatment are discussed.

Gender shifts and effects on behavior guidance.

UNLABELLED: Women's presence in pediatric dentistry has dramatically increased over the past several decades. Women now comprise almost 50 percent of AAPD membership and almost 75 percent of new members. PURPOSE: The purpose of this investigation was to determine differences between male and female pediatric dentists relative to practice patterns and use of behavior guidance techniques (BGTs). METHODS: A web-based survey was sent to 511 pediatric dentists who had been recruited by the AAPD to participate in a series of surveys related to pediatric dentistry. RESULTS: Fifty-nine percent of dentists responded. Fifty-two percent of the respondents were male and 48 percent were female. Female respondents were significantly younger than male respondents. Males were more likely to own a practice and hold leadership positions in dentistry while females were more likely to work as faculty, staff dentists, or part-time in private practice. No significant differences were noted between the genders relative to the use of BGTs, though females tended to involve parents more and were more likely to report the use of protective stabilization in selected situations. Both genders reported that parenthood had an effect on their behavior guidance styles.

Case series: management of immature permanent teeth with pulpal necrosis: a case series.

The management of immature permanent teeth with necrotic pulps has changed in recent years from apexification techniques to regenerative endodontic procedures, which enable apexogenesis with physiologic maturation of the roots. This regenerative technique lies squarely in the endodontist's scope of practice, but children presenting with necrotic immature incisors may pose behavior management problems that endodontists are untrained and unwilling to handle. Treatment of these immature permanent teeth provides an excellent opportunity for collaboration and shared patient management between pediatric dentists and endodontists that can yield optimal clinical outcomes. The purpose of this paper was to report a series of 32 regenerative endodontic cases in 28 children treated at the Nationwide Children's Hospital, Columbus, Ohio. The report describes procedural and patient management issues and the need for a collaborative relationship between pediatric dentists and endodontists in tackling these challenging cases.

Overview of trauma management for primary and young permanent teeth.

This overview covers diagnosis and management of the most common dental injuries in children and identifies those children at greatest risk. Crown fractures and luxation injuries in both the primary and permanent dentition are discussed and treatment options based on current international guidelines are detailed.

Children presenting with dental trauma are more hyperactive than controls as measured by the ADHD rating scale IV.

PURPOSE: Previous studies in the dental traumatology literature have proposed an association between incidence of dental trauma and attention deficit/hyperactivity disorder (ADHD). The purpose of this study was to evaluate the incidence of comorbid dental trauma and ADHD in children presenting for both trauma-related and routine dental care. METHODS: An Institutional Review Board-approved case group series study examined both populations using the attention deficit hyperactivity disorder rating scale IV (ARS). RESULTS: Data were collected from 161 children. There were no differences in overall ARS score or in the inattentiveness subscale. Children with a confirmed recent history of dental trauma did score higher on the hyperactivity/impulsivity subscale (P<.001). There was no difference in subjects scoring above the 90th percentile on the ARS based on group. CONCLUSION: Children presenting with dental trauma scored a higher baseline level of hyperactivity/impulsivity.

Local anesthesia affects physiologic parameters and reduces anesthesiologist intervention in children undergoing general anesthesia for dental rehabilitation.

PURPOSE: The purpose of this study was to evaluate the use of intraoperative local anesthetics in pediatric outpatient dental surgery. This study assessed physiologic stability, as defined by fluctuations in end-tidol carbon dioxide, heart rate, and respiratory rate, as well as subsequent anesthesiologist intervention. METHODS: Forty-eight children (mean age = 3.87 years [+/- l.06 SD]) were included in this randomized, parallel-design study. Intervention variables and the research design were validated in a pilot study. Following collection of baseline vital signs, patients were either given local anesthesia before comprehensive dental treatment or not. Vital sign change was recorded 30 seconds after each procedure. RESULTS: In the no local anesthetic group, 2 areas were found to be statistically significant: (1) postextraction end-tidal carbon dioxide; and (2) heart rate. There was a statistically significant relationship between local anesthetic use and anesthesiologist intervention when assessing the pooled data (P = .001). CONCLUSION: Patients who were not given intraoperative local anesthesia were more likely to experience vital sign fluctuation requiring anesthesiologist intervention.

Managing injuries to the primary dentition.

This article overviews the diagnosis and management of traumatic injuries to primary teeth. The child's age, ability to cooperate for treatment, and the potential for collateral damage to developing permanent teeth can complicate the management of these injuries. The etiology of these injuries is reviewed including the disturbing role of child abuse. Serious medical complications including head injury, cervical spine injury, and tetanus are discussed. Diagnostic methods and the rationale for treatment of luxation injuries, crown, and crown/root fractures are included. Treatment priorities should include adequate pain control, safe management of the child's behavior, and protection of the developing permanent teeth.

Educational issues workshop report.

This panel addressed issues affecting the education of dentists, dental hygienists, and nondental health care providers regarding oral health of persons with special health care needs (PSHCN). The panel was composed of individuals representing: (1) dental education; (2) medicine; and (3) parents of special-needs patients. They were charged with: (1) identifying problems related to the education of dentists and nondental health care providers that influence access to oral health care for PSHCN; (2) developing recommendations for action by the American Academy of Pediatric Dentistry; and (3) prioritizing the problems and recommendations.

Dental education and special-needs patients: challenges and opportunities.

Pediatric dentists have, by tradition and default, provided care for persons with special health care needs (PSHCN), regardless of age. Deinstitutionalization of PSHCN in the 1960s, however, overwhelmed the dental care system, and oral health care became one of the greatest unmet needs of this population. This presentation follows the history of training for dentists in this aspect of care, from the first demonstration programs in the 1970s to the current educational programs in U.S. dental schools. Today's dental students must be competent in assessing the treatment needs of PSHCN, but accreditation standards do not require competency in the treatment of this group of patients. Recommendations to rectify this include revising dental school curricula to be more patient-centered, improving technology in schools, earlier clinical experiences for dental students, and the use of community-based clinics.

Sanguinarine activates polycyclic aromatic hydrocarbon associated metabolic pathways in human oral keratinocytes and tissues.

Sanguinarine's use in human clinical applications is currently controversial. While some studies have demonstrated sanguinarine's anti-inflammatory and anti-oxidant properties, other investigations reported sanguinarine's procarcinogenic effects. Like the tobacco-associated carcinogen, benzo(a)pyrene (B(a)P), sanguinarine is a polycyclic aromatic hydrocarbon (PAH). PAH exposure activates the aryl hydrocarbon transcription activating factor (AhR), resulting in nuclear translocation, binding to the aryl hydrocarbon nuclear translocator (ARNT), which thereby increases expression of a pool of carcinogen metabolizing enzymes. The goal of this study was to investigate whether sanguinarine activates this PAH-associated signaling cascade in human oral cells and tissues. Our results demonstrate that sanguinarine: (i) results in formation of the AhR-ARNT complex, (ii) induces AhR-associated gene expression, (iii) inhibits cytochrome P450 1A1 (CYP 1A1) microsomal oxidative activity and (iv) pretreatment upregulates CYP 1A1 function. Collectively, these data provide evidence that sanguinarine activates PAH-associated signaling and metabolic pathways. Notably, previous studies have demonstrated that mammalian hepatic microsomes metabolize sanguinarine to a mutagenic epoxide. Persons who respond to sanguinarine exposure with induction of primarily Phase I relative to Phase II enzymes are, therefore, at risk for sanguinarine bioactivation and its potential mutagenic effects.
