Craniofacial characterization of Marfan Syndrome.

OBJECTIVE: The morbidity and mortality associated with the Marfan Syndrome (MFS) warrant timely diagnosis and intervention that can improve long-term prognosis. The aim of this study was to test the hypothesis that a distinct craniofacial morphology exists for patients with MFS that can be described quantitatively and qualitatively. METHODS: Subjects with a positive diagnosis of MFS were recruited for this study (N = 36). Craniofacial anthropometric measurements were made on each subject and compared to established norms of age- and sex-matched controls using z-scores calculated for measurements of MFS patients. Lateral and frontal photographs were obtained to make qualitative assessments and describe facial features of subjects, and a clinical examination was completed to document occlusal relationships. RESULTS: The subjects were primarily female (58%) ranging in age between 4 and 57 years (mean age 10.7 ± 6.0 years). Comparison of craniofacial measurements revealed that for 10 of the 12 measurements, ≥65% of the study population had a z-score of ± 2 and fell within the normal range for facial dimension. For 2 of the 12 measurements, over half of the subjects fell outside of the normal range (z-score < -2 or > 2) for facial dimension. Specifically, the majority of participants resided in the supernormal category for biocular width and the subnormal category for width of the face. Photographic assessment revealed retrognathia (54%) and down-slanting palpebral fissures (62%) were most prevalent in MFS patients. CONCLUSION: Our data suggest there are quantitative differences in the facial morphology of patients with MFS when compared to a control population.

An Algorithm for Managing Emergent Dental Conditions for Children.

The amount of emergency department dental utilization and related trend analysis data in peer-reviewed literature has increased; yet, little has been written on the actual management of dental emergencies. Often pre-existing medical conditions complicate what might otherwise be a straightforward dental emergency, challenging office-based dentists to manage dental emergencies in a safe manner. With the profession taking a stance on child safety, algorithms and checklists are becoming more important and common in healthcare during complicated scenarios. Additionally, more children are living longer with chronic medical conditions. This manuscript offers an algorithm that can guide clinicians through challenges presented during a dental emergency in children.

Identification of Preferred Healthy Weight Counseling Approaches for Children in the Dental Setting.

OBJECTIVE: There is a gap in the literature regarding optimal methods for the dental team to help address the childhood obesity epidemic; accordingly, this investigation sought to identify preferred communication approaches the dental team can rely upon to initiate dialogue with caregivers regarding the weight of their children. STUDY DESIGN: A structured interview guide containing seven potential Healthy Weight Counseling (HWC) approaches and eight follow up questions was developed, pilot-tested, revised and utilized as a structured interview guide. Interviews were conducted at the Children's Clinic at the School of Dentistry at the University of North Carolina at Chapel Hill (UNC-CH) with 50 participants who are English-speaking caregivers of children ages 4-12. RESULTS: Ninety-four percent of the participants were receptive to HWC in the dental setting. Caregivers indicated varying levels of acceptance for the seven HWC-approaches based on specific word choices in each approach. Sixty percent preferred HWC to be delivered with the child not present while 34% preferred the child's presence and 6% had no preference. CONCLUSIONS: Caregivers were open to weight-related conversations in the dental setting but to be well received, the dental team must choose their approach carefully and establish the proper doctor/patient relationship prior to HWC delivery. An individualized HWC-approach tailored to the specific needs of each family is indicated.

Neural dynamics of delayed feedback in robot teleoperation: insights from fNIRS analysis.

Introduction: As robot teleoperation increasingly becomes integral in executing tasks in distant, hazardous, or inaccessible environments, operational delays remain a significant obstacle. These delays, inherent in signal transmission and processing, adversely affect operator performance, particularly in tasks requiring precision and timeliness. While current research has made strides in mitigating these delays through advanced control strategies and training methods, a crucial gap persists in understanding the neurofunctional impacts of these delays and the efficacy of countermeasures from a cognitive perspective. Methods: This study addresses the gap by leveraging functional Near-Infrared Spectroscopy (fNIRS) to examine the neurofunctional implications of simulated haptic feedback on cognitive activity and motor coordination under delayed conditions. In a human-subject experiment (N = 41), sensory feedback was manipulated to observe its influences on various brain regions of interest (ROIs) during teleoperation tasks. The fNIRS data provided a detailed assessment of cerebral activity, particularly in ROIs implicated in time perception and the execution of precise movements. Results: Our results reveal that the anchoring condition, which provided immediate simulated haptic feedback with a delayed visual cue, significantly optimized neural functions related to time perception and motor coordination. This condition also improved motor performance compared to the asynchronous condition, where visual and haptic feedback were misaligned. Discussion: These findings provide empirical evidence about the neurofunctional basis of the enhanced motor performance with simulated synthetic force feedback in the presence of teleoperation delays. The study highlights the potential for immediate haptic feedback to mitigate the adverse effects of operational delays, thereby improving the efficacy of teleoperation in critical applications.

Sensory manipulation as a countermeasure to robot teleoperation delays: system and evidence.

In the realm of robotics and automation, robot teleoperation, which facilitates human-machine interaction in distant or hazardous settings, has surged in significance. A persistent issue in this domain is the delays between command issuance and action execution, causing negative repercussions on operator situational awareness, performance, and cognitive load. These delays, particularly in long-distance operations, are difficult to mitigate even with the most advanced computing advancements. Current solutions mainly revolve around machine-based adjustments to combat these delays. However, a notable lacuna remains in harnessing human perceptions for an enhanced subjective teleoperation experience. This paper introduces a novel approach of sensory manipulation for induced human adaptation in delayed teleoperation. Drawing from motor learning and rehabilitation principles, it is posited that strategic sensory manipulation, via altered sensory stimuli, can mitigate the subjective feeling of these delays. The focus is not on introducing new skills or adapting to novel conditions; rather, it leverages prior motor coordination experience in the context of delays. The objective is to reduce the need for extensive training or sophisticated automation designs. A human-centered experiment involving 41 participants was conducted to examine the effects of modified haptic cues in teleoperations with delays. These cues were generated from high-fidelity physics engines using parameters from robot-end sensors or physics engine simulations. The results underscored several benefits, notably the considerable reduction in task time and enhanced user perceptions about visual delays. Real-time haptic feedback, or the anchoring method, emerged as a significant contributor to these benefits, showcasing reduced cognitive load, bolstered self-confidence, and minimized frustration. Beyond the prevalent methods of automation design and training, this research underscores induced human adaptation as a pivotal avenue in robot teleoperation. It seeks to enhance teleoperation efficacy through rapid human adaptation, offering insights beyond just optimizing robotic systems for delay compensations.

A cross sectional study examining social desirability bias in caregiver reporting of children's oral health behaviors.

BACKGROUND: Our previous research (Pediatrics 2010:126) found a strong association between caregiver oral health literacy (OHL) and children's oral health status; however, we found a weak association with oral health behaviors (OHBs). We hypothesize that this may be due to social desirability bias (SDB). Our objectives were to compare caregivers' responses to traditional OHB items and newer SDB-modulating items, and to examine the association of caregiver literacy with OHBs. METHODS: We performed a cross-sectional study of 102 caregiver-child dyads, collecting data for OHBs using both traditional and new SDB-modulating items. We measured OHL using REALD-30, a validated word recognition test. We relied upon percent agreement and Cohen's kappa (k) to quantify the concordance in caregivers' responses and multivariate log-binomial regression to estimate the impact of OHL on OHBs. RESULTS: Caregivers' mean REALD-30 score was 20.7 (SD = 6.0), range 1-30. We found an association between OHL and 4 of 8 OHBs examined. A subset of behavior questions compared traditional versus SDB-modulating items: history of bottle-feeding: agreement = 95%, k = 0.83 (95% CL:0.68,0.99); daily tooth brushing: agreement = 78%, k = 0.25 (95% CL:0.04,0.46); fluoridated toothpaste use: agreement = 88%, k = 0.67 (95% CL:0.49,0.85). After controlling for caregivers' race, marital status and study site, higher literacy scores remained associated with a decreased prevalence of parental report of "decided not brush the child's teeth because it would be frustrating". CONCLUSIONS: Agreement between responses was high for 2 of 3 behavior items. Item 3 (tooth brushing frequency) revealed discordance, likely due to SDB. Use of the SDB-modulating items appears to yield a better estimate of OHB.

The relationship of oral health literacy and self-efficacy with oral health status and dental neglect.

OBJECTIVES: We examined the associations of oral health literacy (OHL) with oral health status (OHS) and dental neglect (DN), and we explored whether self-efficacy mediated or modified these associations. METHODS: We used interview data collected from 1280 female clients of the Special Supplemental Nutrition Program for Women, Infants and Children from 2007 to 2009 as part of the Carolina Oral Health Literacy Project. We measured OHL with a validated word recognition test (REALD-30), and we measured OHS with the self-reported National Health and Nutrition Examination Survey item. Analyses used descriptive, bivariate, and multivariate methods. RESULTS: Less than one third of participants rated their OHS as very good or excellent. Higher OHL was associated with better OHS (for a 10-unit REALD increase: multivariate prevalence ratio = 1.29; 95% confidence interval = 1.08, 1.54). OHL was not correlated with DN, but self-efficacy showed a strong negative correlation with DN. Self-efficacy remained significantly associated with DN in a fully adjusted model that included OHL. CONCLUSIONS: Increased OHL was associated with better OHS but not with DN. Self-efficacy was a strong correlate of DN and may mediate the effects of literacy on OHS.

Pediatricians' assessments of caries risk and need for a dental evaluation in preschool aged children.

BACKGROUND: Risk-based prioritization of dental referrals during well-child visits might improve dental access for infants and toddlers. This study identifies pediatrician-assessed risk factors for early childhood caries (ECC) and their association with the need for a dentist's evaluation. METHODS: A priority oral health risk assessment and referral tool (PORRT) for children < 36 months was developed collaboratively by physicians and dentists and used by 10 pediatricians during well-child visits. PORRT documented behavioral, clinical, and child health risks for ECC. Pediatricians also assessed overall ECC risk on an 11-point scale and determined the need for a dental evaluation. Logistic regression models calculated the odds for evaluation need for each risk factor and according to a 3-level risk classification. RESULTS: In total 1,288 PORRT forms were completed; 6.8% of children were identified as needing a dentist evaluation. Behavioral risk factors were prevalent but not strong predictors of the need for an evaluation. The child's overall caries risk was the strongest predictor of the need for an evaluation. Cavitated (OR = 17.5; 95% CI = 8.08, 37.97) and non-cavitated (OR = 6.9; 95% CI = 4.47, 10.82) lesions were the strongest predictors when the caries risk scale was excluded from the analysis. Few patients (6.3%) were classified as high risk, but their probability of needing an evaluation was only 0.36. CONCLUSIONS: Low referral rates for children with disease and prior to disease onset but at elevated risk, indicate interventions are needed to help improve the dental referral rates of physicians.

Caregivers' oral health literacy and their young children's oral health-related quality-of-life.

OBJECTIVES: To investigate the association of caregivers' oral health literacy (OHL) with their children's oral health related-quality of life (C-OHRQoL) and explore literacy as a modifier in the association between children's oral health status (COHS) and C-OHRQoL. METHODS: This study relied upon data from structured interviews with 203 caregivers of children aged 3-5 from the Carolina Oral Health Literacy (COHL) Project. Data were collected for OHL using REALD-30, caregiver-reported COHS using the NHANES-item and C-OHRQoL using the Early Childhood Oral Health Impact Scale (ECOHIS). This study also measured oral health behaviors (OHBs) and socio-demographic characteristics and calculated overall/stratified summary estimates for OHL and C-OHRQoL. Spearman's rho and 95% confidence intervals (CI) were computed as measures of correlation of OHL and COHS with C-OHRQoL. To determine whether OHL modified the association between COHS and C-OHRQoL, this study compared literacy-specific summary and regression estimates. RESULTS: Reported COHS was: excellent-50%, very good-28%, good-14%, fair-6%, poor-2%. The aggregate C-OHRQoL mean score was 2.0 (95% CI: 1.4, 2.6), and the mean OHL score 15.9 (95% CI: 15.2, 16.7). There was an inverse relationship between COHS and C-OHRQoL: ρ = -0.32 (95% CI: -0.45, -0.18). There was no important association between OHL and C-OHRQoL; however, deleterious OHBs were associated with worse C-OHRQoL. Literacy-specific linear and Poisson regression estimates of the association between COHS and C-OHRQoL departed from homogeneity (Wald χ(2) p < 0.2). CONCLUSION: In this community-based sample of caregiver/child dyads, a strong correlation was found between OHS and C-OHRQoL. The association's magnitude and gradient were less pronounced among caregivers with low literacy.

Emerging therapies for the management of traumatized immature permanent incisors.

Early loss of immature permanent teeth due to pulpal necrosis secondary to trauma can have dire consequences for a child's growth and development. The treatment alternatives include surgical endodontics, traditional calcium hydroxide apexification, and mineral trioxide aggregate (MTA) apexification. These options pose potential complications, including: arrest of root development; weakened dentinal walls; and increased potential for fracture. Revascularization of the dentin-pulp complex is a new approach that involves disinfecting the root canal system followed by tissue repair and regeneration while allowing for continued root development and thickening of the lateral dentinal walls through deposition of new hard tissue. The purpose of this report was to present the revascularization of an immature permanent maxillary central incisor that had evidence of external root resorption. Six months later, internal bleaching was performed to remove cervical discoloration from the triple antibiotic paste. At 18 months, the tooth remained vital and had evidence of continued root development.

Children's oral health-related behaviours and early childhood caries: A latent class analysis.

OBJECTIVE: In this cross-sectional study in a large community-based sample of preschool-age children, we sought to identify distinct clusters of modifiable early childhood oral health-related behaviours (OHBs) and quantify their association with clinical and parent-reported measures of early childhood oral health. METHODS: We relied upon a questionnaire (n = 8033; 11% in Spanish) and clinical oral health data (n = 6404; early childhood caries [ECC] prevalence = 54%] collected in the context of an epidemiologic study of early childhood oral health among 3- to 5-year-old children in North Carolina. Latent class analysis was used to identify clusters of modifiable OHBs based on parents' responses to 6 questionnaire items pertaining to their children's oral hygiene, diet and dental home. The optimal number of clusters was determined based on measures of model fit and interpretability. We examined associations of OHB clusters with clinical and parent-reported child oral health status (ie, ECC prevalence, severity and proportion with untreated disease) using bivariate association tests and multivariable regression modelling with marginal effects estimation accounting for clustered data. We used Mplus v.8.6 (Muthén & Muthén, Los Angeles, CA, USA) and Stata v.16.1 (StataCorp, College Station, TX, USA) for data analyses. RESULTS: We identified 2 OHB clusters, a favourable (74%) and an unfavourable (26%) one. Children in the favourable OHB cluster had better oral hygiene practices (ie, tooth brushing frequency and fluoridated toothpaste use), lower consumption frequency of sugar-containing snacks and beverages, less frequent reports of night-time bottle-feeding history and a higher likelihood of a dental home. Children in the unfavourable cluster had significantly higher ECC prevalence (57% vs 53%), caries burden (mean dmfs = 9.3 vs 7.6), untreated disease (43% vs 33%) and worse parent-reported oral health status than the favourable cluster. CONCLUSIONS: Our findings demonstrate the importance and utility of clustering common, modifiable ECC risk factors in population studies - health promotion efforts may centre on groups of people rather than individual behavioural risk factors.

Impact of poor oral health on children's school attendance and performance.

OBJECTIVES: We examined school days missed for routine dental care versus dental pain or infection to determine the relationship between children's oral health status and school attendance and performance. METHODS: We used 2008 data from the North Carolina Child Health Assessment and Monitoring Program. The study sample, weighted to reflect the state's population, included 2183 schoolchildren. Variables assessed included school absences and performance, oral health status, parental education, health insurance coverage, race, and gender. RESULTS: Children with poor oral health status were nearly 3 times more likely (odds ratio = 3.89; 95% confidence interval = 1.96, 7.75) than were their counterparts to miss school as a result of dental pain. Absences caused by pain were associated with poorer school performance (P < .05), but absences for routine care were not. Mediation analyses revealed that oral health status was associated with performance independent of absence for pain. CONCLUSIONS: Children with poorer oral health status were more likely to experience dental pain, miss school, and perform poorly in school. These findings suggest that improving children's oral health status may be a vehicle to enhancing their educational experience.

The relationship of oral health literacy with oral health-related quality of life in a multi-racial sample of low-income female caregivers.

BACKGROUND: To investigate the association between oral health literacy (OHL) and oral health-related quality of life (OHRQoL) and explore the racial differences therein among a low-income community-based group of female WIC participants. METHODS: Participants (N = 1,405) enrolled in the Carolina Oral Health Literacy (COHL) study completed the short form of the Oral Health Impact Profile Index (OHIP-14, a measure of OHRQoL) and REALD-30 (a word recognition literacy test). Socio-demographic and self-reported dental attendance data were collected via structured interviews. Severity (cumulative OHIP-14 score) and extent of impact (number of items reported fairly/very often) scores were calculated as measures of OHRQoL. OHL was assessed by the cumulative REALD-30 score. The association of OHL with OHRQoL was examined using descriptive and visual methods, and was quantified using Spearman's rho and zero-inflated negative binomial modeling. RESULTS: The study group included a substantial number of African Americans (AA = 41%) and American Indians (AI = 20%). The sample majority had a high school education or less and a mean age of 26.6 years. One-third of the participants reported at least one oral health impact. The OHIP-14 mean severity and extent scores were 10.6 [95% confidence limits (CL) = 10.0, 11.2] and 1.35 (95% CL = 1.21, 1.50), respectively. OHL scores were distributed normally with mean (standard deviation, SD) REALD-30 of 15.8 (5.3). OHL was weakly associated with OHRQoL: prevalence rho = -0.14 (95% CL = -0.20, -0.08); extent rho = -0.14 (95% CL = -0.19, -0.09); severity rho = -0.10 (95% CL = -0.16, -0.05). "Low" OHL (defined as < 13 REALD-30 score) was associated with worse OHRQoL, with increases in the prevalence of OHIP-14 impacts ranging from 11% for severity to 34% for extent. The inverse association of OHL with OHIP-14 impacts persisted in multivariate analysis: Problem Rate Ratio (PRR) = 0.91 (95% CL = 0.86, 0.98) for one SD change in OHL. Stratification by race revealed effect-measure modification: Whites--PRR = 1.01 (95% CL = 0.91, 1.11); AA--PRR = 0.86 (95% CL = 0.77, 0.96). CONCLUSIONS: Although the inverse association between OHL and OHRQoL across the entire sample was weak, subjects in the "low" OHL group reported significantly more OHRQoL impacts versus those with higher literacy. Our findings indicate that the association between OHL and OHRQoL may be modified by race.

Oral health literacy levels among a low-income WIC population.

OBJECTIVES: To determine oral health literacy (OHL) levels and explore potential racial differences in a low-income population. METHODS: This was a cross-sectional study of caregiver/child dyads that completed a structured 30-minute in-person interview conducted by two trained interviewers in seven counties in North Carolina. Sociodemographic, OHL, and dental health-related data were collected. OHL was measured with a dental word recognition test [Rapid Estimate of Adult Literacy in Dentistry (REALD-30)]. Descriptive, bivariate, and multivariate methods were used to examine the distribution of OHL and explore racial differences. RESULTS: Of 1658 eligible subjects, 1405 (85 percent) participated and completed the interviews. The analytic sample (N=1280) had mean age 26.5 (standard deviation = 6.9) years with 60 percent having a high school degree or less. OHL varied between racial groups as follows: Whites--mean score = 17.4 (SE = 0.2); African-American (AA)--mean score = 15.3 [standard error (SE) = 0.2]; American Indian (AI)--mean score = 13.7 (SE = 0.3). Multiple linear regression revealed that after controlling for education, county of residence, age, and Hispanic ethnicity, Whites had 2.0 points (95 percent CI = 1.4, 2.6) higher adjusted REALD-30 score versus AA and AI. CONCLUSIONS: Differences in OHL levels between racial groups persisted after adjusting for education and sociodemographic characteristics.

The UNC-CH MCH Leadership Training Consortium: building the capacity to develop interdisciplinary MCH leaders.

This article describes the UNC-CH MCH Leadership Consortium, a collaboration among five MCHB-funded training programs, and delineates the evolution of the leadership curriculum developed by the Consortium to cultivate interdisciplinary MCH leaders. In response to a suggestion by the MCHB, five MCHB-funded training programs--nutrition, pediatric dentistry, social work, LEND, and public health--created a consortium with four goals shared by these diverse MCH disciplines: (1) train MCH professionals for field leadership; (2) address the special health and social needs of women, infants, children and adolescents, with emphasis on a public health population-based approach; (3) foster interdisciplinary practice; and (4) assure competencies, such as family-centered and culturally competent practice, needed to serve effectively the MCH population. The consortium meets monthly. Its primary task to date has been to create a leadership curriculum for 20-30 master's, doctoral, and post-doctoral trainees to understand how to leverage personal leadership styles to make groups more effective, develop conflict/facilitation skills, and identify and enhance family-centered and culturally competent organizations. What began as an effort merely to understand shared interests around leadership development has evolved into an elaborate curriculum to address many MCH leadership competencies. The collaboration has also stimulated creative interdisciplinary research and practice opportunities for MCH trainees and faculty. MCHB-funded training programs should make a commitment to collaborate around developing leadership competencies that are shared across disciplines in order to enhance interdisciplinary leadership.

Correlation between laser fluorescence readings and volume of tooth preparation in incipient occlusal caries in vitro.

OBJECTIVE: This study evaluated the correlation between laser fluorescence readings and the extent of incipient occlusal caries as measured by the volume of tooth preparation in vitro. MATERIALS AND METHODS: One hundred and three permanent molars and premolars containing incipient occlusal pit-and-fissure caries and sound occlusal surfaces (1/4 of the sample, control) were selected. DIAGNOdent (KaVo Dental Corporation, Lake Zurich, IL, USA) readings were obtained according to manufacturer instructions. Caries was removed with 1/4 round burs in high speed. The volume of tooth preparation was measured using a surrogate measure based on the amount of composite needed to fill the preparations. Sensitivity and specificity using different cutoff values were calculated for lesions/preparations extending into dentin. The results were analyzed statistically. RESULTS: The Pearson correlation for preparation volume and DIAGNOdent reading measurements was low (r = 0.285). Sensitivity and specificity of DIAGNOdent for detection of dentinal lesions were 0.83 and 0.60, and 0.66 and 0.73 for the cutoff values of 20 and 30, respectively. CONCLUSIONS: Within the limitations of this study, laser fluorescence measured with DIAGNOdent does not correlate well with extent of carious tooth structure in incipient occlusal caries. CLINICAL SIGNIFICANCE: Clinicians should not rely only on DIAGNOdent readings to determine the extension of incipient occlusal caries.

Addressing childhood overweight and obesity in the dental office: rationale and practical guidelines.

The prevalence of childhood obesity has increased dramatically in the past 3 decades. The purposes of this paper were to: review health and dental implications; present guidelines for tracking body mass index (BMI) percentiles in children; and discuss reasonable "next steps" to take in communicating with parents and other health professionals. The health implications of childhood obesity warrant early monitoring, diagnosis, and treatment. Trends in visitation patterns of children offer dentists an unusual opportunity and an important role in addressing childhood obesity through regular monitoring of height, weight, and BMI percentiles. Dentists' collaborations with pediatricians, registered dietitians, and parents have the potential to address the detrimental physical and psychosocial effects of childhood obesity. We encourage dentists to determine height, weight, and BMI percentiles for their patients at least annually. They should refer patients with unhealthy weight trajectories to pediatricians or family physicians and consider ancillary referrals to registered dietitians.

Two case reports of complicated permanent crown fractures treated with partial pulpotomies.

The partial pulpotomy can offer a superb outcome for the treatment of traumatic complicated crown fractures. The procedure is often used for dental trauma in children when the major aim of treatment is to preserve tooth vitality while providing a favorable environment for continued root development. The purpose of this paper was to review scientific evidence supporting partial pulpotomy and its high success rate and illustrate the clinical technique by presenting 2 challenging cases of complicated crown fractures with long-term follow-up.

Permanent tooth replantation following avulsion: using a decision tree to achieve the best outcome.

An avulsion injury is a challenge to manage and there are many treatment options to consider to obtain the best prognosis depending on the avulsion scenario. In 2001, Lee et al published decision analysis paradigms for the management of avulsed permanent teeth to provide busy clinicians with user-friendly, referenced-based flowcharts to facilitate the best possible outcomes for managing these teeth in children and adolescents. The flowchart was updated in 2007 by McIntyre et al. The purpose of this paper is to update the 2001 and 2007 flowcharts and decision analyses with current concepts, recent literature-based findings, new treatment philosophies, and expert consensus from the 2008 AAPD Dental Trauma Symposium.

Measurement of maximum tongue protrusion force (MTPF) in healthy young adults.

We propose that tongue protrusive strength and tone may be related to upper airway patency, and when protrusive strength is reduced, individuals are at higher risk of developing sleep apnea, or speech/swallow disorders. The goal of the current study was to determine normative values of maximum tongue protrusion force (MTPF) in healthy young adults, using a unique newly developed device. We hypothesized that MTPF would be greater in males than in females. One hundred and one healthy young adults (mean age: 22.99 years; male: 23, female: 78) participated in this study. The subjects pushed their tongue forward against the device's piston (protrusion) as hard as possible for 2-5 sec and MTPF was recorded in Newtons (N). A minimum of 5 MTPF measurements were obtained with 1-2 min rest between measurements. The average MTPF for all subjects was 15.4 N (SD: ±3.8), with a range of 8-29. The male average MTPF was higher than female (17.8 N, SD: ±3.7 vs. 14.7 N, SD: ±3.5; P = 0.001). There was no significant difference for age between males and females; males had significantly greater height and weight. The results demonstrate our novel device can effectively measure tongue protrusive force in healthy young adults. This study provides normative values for MTPF, and identified significant tongue protrusion strength differences between males and females.
