In vitro remineralization of adjacent interproximal enamel carious lesions in primary molars using a bioactive bulk-fill composite.

BACKGROUND: Surface remineralization is recommended for the management of active non-cavitated interproximal carious lesions in primary teeth. According to the American Academy of Pediatric Dentistry, a recently recognized category of materials called bioactive restorative materials can be used for remineralization. This study aimed to evaluate the release of fluoride (F), calcium (Ca) and phosphate (P) ions from Predicta® Bioactive Bulk-fill composite compared with EQUIA Forte® and Filtek™ Z350 and to determine the remineralization effect of these 3 restorative materials on adjacent initial interproximal enamel carious lesions. METHODS: The release of F, Ca and P ions from 3 groups ((n = 10/group) (Group 1- Predicta®, Group 2- EQUIA Forte® and Group 3- Filtek™ Z350)) was determined at 1st, 4th, 7th and 14th days. After creating artificial carious lesions, human enamel samples were randomly assigned into 3 groups (n = 13/group) which were placed in contact with occluso-proximal restorative materials and exposed to a 14-day pH cycling period. Surface microhardness was determined using a Knoop microhardness assay at baseline, after artificial carious lesions formation and after pH cycling. The difference in the percentage of surface microhardness recovery (%SMHR) among groups was compared. Mineral deposition was analyzed with energy-dispersive x-ray spectroscopy (EDS) and the enamel surface morphology was evaluated with scanning electron microscopy (SEM). Kruskal-Wallis's test with Dunn's post hoc test and one-way ANOVA with Tukey's post hoc test were used for data analysis. RESULTS: EQUIA Forte® released the highest cumulative amount of F and P ions, followed by Predicta® and Filtek™ Z350. Predicta® released higher amount of Ca ions than EQUIA Forte® and Filtek™ Z350. Predicta® demonstrated the highest %SMHR, followed by EQUIA Forte® and Filtek™ Z350. There was a significant difference in the %SMHR between Predicta® and Filtek™ Z350 (p < 0.05). However, EQUIA Forte® demonstrated the highest fluoride content, followed by Predicta® and Filtek™ Z350. The SEM images of EQUIA Forte® and Predicta® revealed the greater mineral deposition. CONCLUSION: Predicta® demonstrated a marked increase in surface microhardness and fluoride content of adjacent initial interproximal enamel carious lesions in primary molars compared with Filtek™ Z350. Predicta® is an alternative restorative material to remineralize adjacent initial interproximal enamel carious lesions in primary molars, especially in high-risk caries patients.

Articaine Infiltration Versus Lidocaine Inferior Alveolar Nerve Block for Primary Mandibular Molars: A Double-blind Randomized Controlled Clinical Trial.

Purpose: To compare the effectiveness of articaine local infiltration with lidocaine inferior alveolar nerve block (IANB) for restorative treat- ment of primary mandibular molars (PMMs). Methods: In this double-blind, parallel-design, randomized, controlled, clinical trial, participants were enrolled according to specified inclusion criteria (four to 10 years of age, need of PMM restorations, Frankel four behavior) and randomly assigned into either an articaine or lidocaine group. One investigator administrated all local anesthesia (LA). Nineteen trained and calibrated exam- iners, blinded to LA type, evaluated participants' reactions during LA administration and treatment using Modified Behavioral Pain Scale (MBPS). Participants rated their experiences using Wong-Baker FACES Pain Rating Scale (WBFS). The subjects' blood pressure and pulse were recorded throughout procedures. Statistical analysis employed Mann Whitney-U test, repeated measures analysis of variance (P<0.05), and Cohen's kappa. Results: A total of 110 participants (n equals 55 per group; mean age equals 6.42 years; 60 percent males) were enrolled. The mean MBPS rating during LA administration was higher for lidocaine IANB (3.89) compared to articaine infiltration (2.24; P<0.001). The mean MBPS rating through- out treatment was higher for the lidocaine group (2.51) compared to articaine group (1.69; P=0.012). The lidocaine group had a mean WBFS score of 1.64, while for the articaine group WBFS was 0.872 (P=0.089). All physiological measurements were within normal limits with no difference between groups. Conclusions: This study demonstrated that local infiltration with articaine was less distressing upon administration and may be considered safe and effective alternative to lidocaine IANB for restorative treatment in PMMs.

Comparing the relative influence of obesity and ancestry on timing of dental development.

INTRODUCTION: The dentition is one of the most accurate features for age estimation in children. However, there is some evidence that timing of dental development varies across populations. Recent research suggests that dental development may also be susceptible to influence by environmental factors, such as obesity. Given that there are also population differences in average body mass, it is possible that this may be a confounding variable that was not accounted for in prior work. We aim to compare the relative association between body mass index (BMI) and ancestry with timing of dental development. METHODS: A retrospective cross-sectional chart review was undertaken using panoramic radiographs of 6- to 12-year-olds (n = 281). Age, ancestry, sex, height, and weight were obtained. Dental development was assessed using the Demirjian method, and chronological age was subtracted from estimated dental age to determine relative timing of dental development (ΔAge). BMI was calculated based upon recorded height/weight within 6 months of time of radiograph. RESULTS: We found no difference in timing of dental development (accelerated/delayed) across ancestry groups (African-American, Euro-American, Hispanic, Asian; P = .15). Overweight/obese subjects had statistically significantly advanced (precocious) dental development (P < .001). Compared to normal-weight subjects, children who were overweight's age were overestimated by 5.76 months (0.48 years) and children with obesity by 5.97 months (0.49 years) on average. CONCLUSIONS: BMI appears to have a greater impact on relative timing of dental development than ancestry in this population. Our results support other findings that obesity results in accelerated growth and development.

Vaso-occlusive Pain Crisis Mimicking Mandibular Abscess in an Adolescent with Sickle Cell Disease.

In people with sickle cell disease (SCD), oral abscesses are concerning clinical conditions and carry a high risk of postoperative sickle cell complications. We present an unusual case of a 14-year-old girl with SCD whose initial presentation of facial swelling, headaches, jaw pain, and paresthesia mimicked an odontogenic abscess. She was diagnosed with vaso-occlusive crisis in the mandibular bone and successfully managed noninvasively. This is among the youngest cases of paresthesia in the lower lip in SCD, which provided a clue that postponing invasive aspiration or biopsy was possible under empiric antibiotics and close observation.

Prevalence of Radiographically Identifiable Dental Anomalies in Children and Association with Health Status.

Purpose: The purpose of this study was to describe the prevalence of radiographically identifiable developmental dental anomalies (DDA) in a university-based pediatric dental clinic and to assess for associations between DDA and health status. Methods: Retrospective data, obtained from the electronic dental records of a three-year pediatric patient cohort, were evaluated by two trained and calibrated examiners. Strict inclusion/ exclusion criteria were applied. A validated image quality grading system was used for radiograph assessment, and the physical status classification of the American Academy of Anesthesiology was utilized. A chi-square test and bivariate logistic regression were used for statistical analysis. The inter- and intraexaminer reliability was assessed using Cohen's Kappa. Results: A total of 1,478 subjects (69 percent medically healthy) were enrolled. DDA were identified in 25 percent of the subjects, with hyperdontia, hypodontia, and microdontia being more common. A statistically significant association was found between the presence of DDA and health status (P<0.001) and between DDA and asthma (P=0.035). Patients with systemic disturbances showed 2.12 times greater odds of having DDA (P<0.001, 95 percent confidence interval equals 1.7-2.7). Conclusions: The prevalence of developmental dental anomalies was high, with one in four patients affected. DDA in number were the most common. Patients with systemic disturbances had greater odds of having DDA.

Nitrous Oxide for Dental Procedures in Pediatric Patients with Sickle Cell Disease: A Pilot Study.

Purpose: The purpose of this pilot study was to evaluate the safety of nitrous oxide (N2O) during dental procedures in pediatric patients with sickle cell disease (SCD). Methods: Patients three to 15 years of age received N2O with oxygen (N2O:O2) during their dental procedure in a university pediatric dental clinic between March 2019 and December 2020. Blood oxygen levels were monitored via pulse oximetry throughout the visit. Caregivers received a follow-up call to assess for postoperative complications. Results: Twenty-three patients were enrolled. The duration of N2O sedation was 20 to 50 minutes. Oxygenation levels during (P<0.001) and after (P=0.004) the procedure were higher than for baseline. No adverse effects were reported in the three days after N2O use. Conclusions: Following dental guidelines for sedation, treatment with up to a 50:50 mixture of nitrous oxide with oxygen increased blood oxygen levels and did not cause postoperative complications in children with sickle cell disease. This is the first formal study confirming the safety of nitrous oxide use in the dental care of SCD patients.

Articaine Infiltration Versus Lidocaine Inferior Alveolar Nerve Block for Anesthetizing Primary Mandibular Molars: A Randomized, Controlled, Double-Blind Pilot Study.

Purpose: The purpose of this study was to compare the effectiveness of articaine local infiltration to lidocaine inferior alveolar nerve block (IANB) for restorative treatment of primary mandibular molars (PMM). Methods: Four- to 10-year-old children who needed PMM restorations were enrolled according to inclusion criteria and randomly allocated into the articaine or lidocaine group. One operator administered all local anesthesia. Using the Modified Behavioral Pain Scale (MBPS), 15 trained and calibrated examiners, blinded to LA type, evaluated the subjects' reactions during LA administration and treatment. Children rated their experience using the Wong-Baker FACES Pain Rating Scale (WBS). Subjects' blood pressure and pulse throughout the visits were recorded. Statistical analysis included independent t-tests, Mann Whitney-U, and repeated measures analysis of variance (P<0.05). Examiner reliability was determined by Cohen's kappa score. Results: Thirty subjects (53 percent male; mean age: 6.3 years) participated. While the mean total scores for articaine (2.13 MBPS; 0.53 WBS) were better than for lidocaine (3.07 MBPS; 1.33 WBS), there were no statistically significant differences between groups. All physiological measurements were within normal limits. Conclusions: This pilot study indicated that articaine infiltration might be as effective as a lidocaine inferior alveolar nerve block for restorative treatment of primary mandibular molars; however, a larger sample is required to confirm these findings.

Oral Health Implications of Risky Behaviors in Adolescence.

Adolescence is a time for new discoveries, which may lead teens to engage in impulsive behaviors. Although social media and the Internet have brought great benefits to the world, they can also have a negative influence on adolescents, facilitating their engagement in risky behaviors. Positive parenting and healthy friendships in adolescence have a protective effect against sensation-seeking behaviors. Dental practitioners also have a significant role in steering young patients toward healthy behaviors. They play an essential role in the early recognition, initiation of appropriate interventions, and referrals for treatment of youth at risk.

Dental Considerations in Patients with Loeys-Dietz Syndrome: A Review of the Literature and Case Report.

Loeys-Dietz Syndrome (LDS) is a rare connective tissue disorder with an autosomal dominant pattern of inheritance, linked to heterozygous mutations in six genes from the transforming growth factor beta receptor complex. The classical syndrome characteristics include aortic aneurisms with generalized arterial tortuosity, hypertelorism and cleft palate or bifid/broad uvula. LDS is also associated with a wide range of skeletal, craniofacial, cutaneous and ocular abnormalities, as well as allergic, atopic and inflammatory diseases. Common oral findings include high arched and/or narrow palate, enamel defects and class II skeletal malocclusion. Dental management of patients with LDS is complex and includes approaches to prevent medical complications, as well as considerations for safe delivery of dental care. The purpose of this report, reviews the literature related to LDS oral manifestations as well as to describe the comprehensive dental management of an adolescent patient with LDS and discuss the challenges that dental practitioners may face when providing treatment for these patients. LDS is a newly described syndrome and the literature reviewing its oral manifestations is limited. Patients are reported to have lower oral health-related quality of life as a result of tooth sensitivity and malocclusions. Dental management is compounded by the complexity of medical factors that should be taken into consideration for the safe delivery of care. The presented case is an example of the challenges that dental practitioners may face when providing treatment for LDS patients.

Caregivers' Comfort Answering Sensitive Questions About Themselves and Their Children in a Pediatric Dental Setting.

Purpose: The purpose of this study was to explore caregivers' comfort levels and preferences for answering sensitive questions about themselves and their children in a pediatric dental setting. Methods: An electronically delivered survey was completed by 206 caregivers in the waiting area of a dental school's pediatric clinic. The survey items assessed were demographic, general health, behavioral health, oral health, and living conditions. A factor analysis was conducted for each set of questions, and a mean comfort level was calculated for each factor. Comfort levels were assessed on a five-point Likert scale, with one being least comfortable and five being most comfortable. Results: The questions caregivers were less comfortable answering about themselves were concerning traumatic events, stress, coping (mean equals 3.39), and living conditions (mean equals 3.24) versus demographics (mean equals 3.84) and physical and oral health (mean equals 3.99; P<0.001). They were also less comfortable answering questions about their children's trauma, stress, coping (mean equals 3.65), and experiences with violence and sexual activity (mean equals 3.13) than about demographics/general health (mean equals 4.11) and oral health (mean equals 4.21; P<0.001). The main reasons for the discomfort were the questions' sensitive nature and their belief that they had any relationship to their children's oral health. Conclusion: This study provides knowledge of caregivers' lower comfort levels discussing sensitive topics in a dental setting and provides context for interventions focused on how dentists can better communicate with caregivers about their own adverse experiences as well as their children's.

Success of Biodentine and Ferric Sulfate as Pulpotomy Materials in Primary Molars: A Retrospective Study.

OBJECTIVE: To determine the clinical and radiographic success of Biodentine® (BD) and Ferric Sulfate (FS) as primary molar pulpotomy materials and to compare their outcomes. STUDY DESIGN: Retrospective data was obtained from the electronic health records (EHR) of a university-based pediatric dental clinic. Participants were enrolled according to specified inclusion and exclusion criteria. Two trained and calibrated examiners evaluated the EHR using validated criteria for clinical and radiographic outcomes. Study data was numerically coded and analyzed. Cohen's Kappa and Chi-square tests were used (p<0.05). RESULTS: Eighty-three participants (62.7% females, age range two to eight years, average age of 4.5 years) with 102 pulpotomies were enrolled. FS was used in 78% (n=79) and BD in 22% (n=23) of the cases. Follow-up periods ranged from six to 36 months (mean of 17 months). BD showed 100% clinical and radiographic success, while FS demonstrated 84% clinical and 70% radiographic success. The two groups were compared at one year with no statistically significant differences. At 18 months, BD outperformed FS clinically (p=.012) and radiographically (p=.001). Intra-rater and inter-rater agreement were κ>0.88. CONCLUSIONS: Both materials can be recommended for clinical practice, however BD may be the preferred choice for its better outcomes at 18 months.

Female Caregivers' Depression Risk Affects Children's Attendance to Dental Appointments: A Pilot Study.

Purpose: This pilot study aimed to evaluate the association between women's depression risk and their children's return for dental treatment. Methods: A total of 175 female caregivers of children presenting for an initial dental examination between May and October 2019 at a university clinic answered demographic questions and a validated survey on depression risk. An analysis of caregiver's depression risk relative to children's attendance at the next treatment appointment was made. Results: One hundred and eight female caregivers were included in the analysis. Average age was 33 years (standard deviation ± 6.5 years), and 52 percent were Hispanic. The rate of risk for depression was 17.5 percent. Most women at risk lived at least 20 miles away, had an income of less than $29,999, were unemployed or employed part-time, and had no help with childcare. White caregivers were more likely to fail to attend their child's appointment (chi-square [X²] = 7.80, P=0.02) while Hispanic women were more likely to return (X² = 4.10, P=0.04). Caregivers with low depression risk were more likely to return for the child's scheduled appointment (X² = 13.37, P<0.001). Thus, there was a positive association between high depression risk and failed appointments (r=0.474, P<0.01). Conclusion: Children of women at risk for depression are more likely to fail to attend their dental appointment.

Gender Differences in Pediatric Dentistry Chairs in the United States and Canada.

OBJECTIVE: To analyze gender differences in personal and professional demographics, job perceptions and work satisfaction between male and female pediatric dentistry academic leaders in the United States and Canada. STUDY DESIGN: A 40-question survey was sent electronically to department chairs requesting information about demographics, current circumstances of the position, professional history, and opinions about the position. Data was analyzed by the sex of the respondent. RESULTS: Eighty-eight surveys were distributed electronically and 55 chairs responded (response rate: 62.5%). Women comprised 29.5% of the sample, were younger and had less leadership training than men. Men had served longer in the position (t(41)=2.02, p=0.05) and had higher ranking academic titles. Women spent more time managing personnel (p=0.026), creating courses and programs (p=0.029), and teaching (p=0.006) than men. Female chairs perceived to have a difficult relationship with the faculty (p=0.027), felt they received less faculty support (p=0.002), and were significantly more dissatisfied in the job (p=0.037). Men were more stressed about a heavy workload than women (p=0.001). CONCLUSION: Gender was significantly related to the demographics, experience, perceptions of the skills and abilities required for job performance, time management and job satisfaction for pediatric dentistry department chairs in American and Canadian institutions.

Characteristics and Professional Development Needs of Pediatric Dentistry Chairs in the United States and Canada.

Purpose: To describe the demographics of pediatric dentistry department chairs in the United States and Canada, characterize the skills and abilities required for the job, understand how they spent their time, and identify their professional development needs. Methods: An electronic survey was sent to 88 department chairs about personal demographics, leadership, management and personal qualities important for the job, and professional developmental needs. The data were analyzed using descriptive statistics. Results: The response rate was 62.5 percent. The respondents' mean age was 54.5 years (±8.9 years standard deviation); 68.2 percent of respondents were male, and 57 percent were Caucasian non-Hispanic. Most obtained their dental degree and specialty training in the USA, and 85 percent were board certified. They worked an average of 49.4 hours a week, spending a lot of time dealing with communications, teaching, and administrative materials. More than 80 percent lacked clear job expectations provided to them or they were only reviewed verbally. A minority (10.8 percent) was dissatisfied or very dissatisfied with the job. Conclusions: Most chairs were Caucasian, male, challenged by faculty and administrative issues and received no clear expectations for the job but were satisfied overall. Developing leadership and mentorship skills were important for the job execution.

Effect of Overlying Material on Final Setting of Biodentine ® in Primary Molar Pulpotomies.

Purpose: The purpose of this study was to evaluate and compare in vitro the effect of overlying materials, including zinc oxide eugenol (ZOE), resin-modified glass ionomer cement (RMGIC), and stainless steel crowns (SSC) cemented with glass ionomer cement (GIC), on the setting of Biodentine ® (BD) used as a pulpotomy agent in primary molars that were restored definitively in a single visit. Methods: Forty extracted primary molars were prepared to replicate pulpotomy procedures. The teeth were randomly allocated to four restorative groups: (1) BD, ZOE, SSC; (2) BD, RMGIC, SSC; (3) BD, SSC; (4) BD only (control). All samples were incubated for 24 hours, sectioned mesial-distally, and polished. BD setting was measured as a function of Knoop hardness value (HK) using a Leco Microhardness Tester. Each sample was tested in three zones with 50 gf load force and 30 seconds dwell time and at one, two, and three mm distance from the BD-material interface. A one-way analysis of variance was used to determine statistical significance between groups (P<.05). Results: There was no statistically significant difference between the mean HK value among the four groups and three zones. Conclusions: Overlying materials, including zinc oxide eugenol, resin-modified glass ionomer, and stainless steel crowns cemented with glass ionomer cement, showed no effect on the BD final set. This in vitro study found no evidence against immediate definitive restoration of Biodentine ® pulpotomies.

Age estimation of Hispanic children using the London Atlas.

PURPOSE: To test the accuracy of the London Atlas for age estimation of Hispanic children and to determine if there is any difference in age accuracy between Hispanic males and females. METHODS: The London Atlas was used to estimate age from panoramic radiographs of 17 males and 17 females for each year of age from six to 15.99 years, using the electronic patient database of a dental school. Exclusion criteria included gross pathology, hypodontia, hyperdontia, and previous orthodontic treatment. RESULTS: There were 332 panoramic radiographs evaluated. In all age groups, 34 radiographs (from 17 males and 17 females) were reviewed, except for the age bracket 6-6.99 years, for which only 26 radiographs were available. The mean age estimated of the entire sample by the London Atlas (11.44 years) was greater than the mean chronological age (11.09 years), which was statistically significant (P<.001). The mean difference between chronological and estimated ages for males was .30 years and for females was .40 years, but the difference between sexes was not significant (P=.324). One hundred sixty-two radiographs (49%) were estimated to the exact age interval while 45 (14%) were under-estimated and 125 (38%) were over-estimated. Two hundred and forty radiographs (72%) were estimated to a value within one year of the actual age. CONCLUSION: There was no difference in age estimation prediction accuracy between Hispanic males and females but an age overestimation of three percent in the cohort was seen. The London Atlas accuracy is suitable for use in forensic investigation.

Caretakers' Self-Selected Oral Health Goals: Self-Efficacy, Perceived Compliance, and Effect on Recall Attendance.

PURPOSE: The purpose of this study was to describe caretakers' self-selected pediatric oral health goals, self-reported compliance, perceived self-efficacy, and perceived barriers to goal accomplishment. The effect of self-management plans on recall attendance was also evaluated. METHODS: Fifty caretaker-patient pairs who presented for examinations at a university pediatric dental clinic were assigned to an intervention group. Fifty age-matched subjects were assigned to the comparison group. At baseline both groups completed a demographic survey. The intervention group developed a self-management plan and selected oral health goals. Follow-up surveys were administered to the intervention group two weeks and six months later. RESULTS: The most frequently selected oral-health goals were brush twice daily (21 percent) and toothbrush before bed (17 percent). At the two-week follow-up, 39 percent of contacted caretakers recalled their chosen goals correctly, compared to 26 percent at six months. Approximately half of the participants in both groups attended the six-month follow-up visit. The difference in recall attendance between intervention and comparison group was not significant (P=0.80). CONCLUSIONS: Caretakers most frequently selected goals that were associated with toothbrushing. They initially reported high confidence levels; however, recall and compliance with self-selected oral-health goals decreased significantly over the course of six months.

Social Determinants of Pediatric Oral Health.

Social determinants of health are defined as conditions in which people are born and live and the role these conditions play on health outcomes. Research indicates that risk factors and their interactions are far more complex than originally thought. This article outlines social determinant constructs and their role in understanding oral health promotion. Due to the complex interactions, oral health must be promoted using a multilevel chronic disease model or common risk factor approach. An understanding of social determinants is particularly important for the pediatric population because optimum oral health and general health in adulthood are heavily influenced by childhood.

Association Between Childhood Traumatic Stress and Behavior in the Pediatric Dental Clinic.

PURPOSE: The purpose of this study was to examine the relationship between a history of potentially traumatic events (PTE) and a child's behavior during dental treatment. METHODS: Parents of healthy children, age four years and older and attending their initial dental appointment at a university pediatric dental clinic, were asked to complete the Traumatic Events Screening Inventory-Parent Report Revised and a demographic survey. Following the dental appointment, a pediatric dental resident reported the child's behavior using the Frankl scale. RESULTS: A total of 170 parent-child pairs participated; 53 percent of parents indicated their child had experienced at least one PTE; 44 percent reported their child had a prior negative experience at the dentist. Adjusted multivariable logistic regression analysis showed no significant association between PTE history and poor dental behavior (P=0.994), but a significant association was observed between a previous negative dental experience and poor dental behavior (P=0.000) as well as between age (younger than five years old) and poor behavior (P=0.006). CONCLUSIONS: Children with a history of potentially traumatic events did not exhibit uncooperative behavior more often than those who did not. A previous negative dental experience and the child's young age were significantly associated with uncooperative behavior.
