Purpose: To assess the setting of premixed mineral trioxide aggregate (NuSmile NeoPUTTY) when used as a pulpotomy agent in primary molars, restored in a single visit, and to compare the effect of overlying materials, including zinc oxide eugenol (ZOE), resin-modified glass ionomer cement (RMGIC) and stainless steel crowns (SSC), on the microhardness of the NeoPUTTY.
Methods: Forty-eight extracted primary molars were prepared with the standard pulpotomy technique. Approximately three mm of NeoPUTTY were placed on the pulpal floor of each tooth. The teeth were divided into four groups according to restorative material: (1) control group-none; (2) RMGIC; (3) ZOE; and (4) ZOE and SSC. Groups 2, 3 and 4 specimens were placed in artificially simulated oral cavity conditions. After 24 hours, all teeth were sectioned mesiodistally and polished. Microhardness was then measured in Knoop scales (HK) at one mm, two mm and three mm away from the NeoPUTTY-overlying material interface following the application of a 25-gf load force for 30 seconds at each site. One-way analysis of variance was used to compare the NeoPUTTY microhardness values between groups at each depth as well as between the three different depths within each group (P <0.05).
Results: No statistically significant differences in mean HK values (57.9 to 62.3 range) were found between groups at each depth, or between depths within each group (Group 1,P =0.328; Group 2, P =0.74; Group 3, P =0.293; Group 4, P =0.788).
Conclusion: The setting reaction of NeoPUTTY, as a function of microhardness, was not affected by the presence or type of overlying material used in a single-visit pulpotomy. This in vitro study found no evidence against the immediate restoration of primary molar pulpotomies done with NeoPUTTY.

Purpose: To evaluate the association between attention-deficit/hyperactivity disorder (ADHD) symptoms reported by parents and the variables sleep problems, possible sleep bruxism, possible awake bruxism and dental trauma (DT), and its mode of occurrence in children and adolescents.
Methods: A cross-sectional study was conducted with the parents of 144 four- to 16-year-old subjects through a questionnaire on demographics, subjects' sleep, self-reported bruxism and DT mode of occurrence. The Swanson, Nolan and Pelham scale IV was used to assess ADHD signs and subtypes. Bivariate and multivariate analysis were performed (P <0.05).
Results: The subjects' mean age was 7.9 years (±2.8 years) and 50.7 percent were boys. DT was reported in 80 percent of those with the hyperactive/impulsive subtype (ADHD-HI) and 72.7 percent of those with the combined subtype (ADHD-C). DT was caused solely by falls in the ADHD-C and inattention subtypes (ADHD-I). ADHD-C was associated with somniloquy (prevalence ratio [PR]=1.075; P =0.010). ADHD-HI was associated with bad sleep quality (PR=1.194; P =0.005), possible sleep bruxism (PR=1.088, 95% confidence interval=1.006 to 1.176; P =0.034), possible awake bruxism (PR=1.146; P =0.024) and sleep duration (PR=0.88; P =0.02).
Conclusion: ADHD-C and -HI subtypes were associated with sleep characteristics. Possible sleep and awake bruxism were associated with symptoms of ADHD-HI. Despite no significant association, DT was present in most ADHD subjects, mostly due to falls.

Purpose: To compare the effective dose (E) of the Tru-Image® rectangular collimator and the universal round collimator of a Planmeca® wall-mounted radiograph unit for two bitewing radiographs (right and left) on a pediatric phantom.
Methods: Absorbed doses utilizing the Tru-Image ®rectangular collimator and universal round collimator were acquired using an anthropomorphic 10-year-old child phantom. Each set of 24 dosimeters was exposed to two bitewing exposures with the manufacturer's child settings. Fifty clinical exposures were completed for each set and three sets were exposed for each collimator. The average E per exposure was calculated.
Results: The overall E for the Tru-Image ®rectangular collimator and the universal round collimator were 6.3 microsieverts (μSv) and 25.3 μSv, respectively. This difference was statistically significant (P <0.001). The highest equivalent dose for both collimators was delivered to the oral mucosa. When compared to the universal round collimator, the Tru-Image ® rectangular collimator had significant dose reduction at all locations (P <0.05). When normalized and adjusted to the same source-to-end distance, there was an overall 65 percent dose reduction with the rectangular collimator.
Conclusion: The average effective dose was significantly reduced with the use of the Tru-Image ®rectangular collimator. Clinical use of this rectangular collimator should be considered in the pediatric population.

Purpose: To evaluate the efficacy in dental biofilm (DB) removal between electric toothbrushes versus manual toothbrushes in primary dentition using an Image Analysis System (IAS) of digital photographs.
Methods: A prospective, randomized, controlled, blind, crossover clinical trial was conducted for 12 weeks with children between four to six years of age. The amount of DB was evaluated at zero, four, eight and 12 weeks. The degree of acceptance of the type of toothbrush used by the child was assessed at week 12.
Results: Twenty-two children participated and 176 photographs were taken, with 1,408 images of primary incisors being digitally analyzed by IAS. DB was significantly reduced by both types of toothbrushes on day zero (manual=7.44±1.83 percent; electric= 9.80±2.03 percent) and at week four (manual=8.57±2.23 percent; electric= 5.85±2.10 percent). However, there was no statistically significant difference in DB reduction when both types were compared. After week four, when compared prospectively, there was a statistically significant reduction (P <0.05) of DB for the electric toothbrush only. Electric toothbrushes had a significantly greater acceptance by the participants (P <0.01).
Conclusion: Electric toothbrushes eliminated DB better and were more accepted by the children than manual toothbrushes.

The purpose of this paper is to discuss the avulsion of a primary maxillary first molar in a 22-month-old child, which occurred while she had a training cup in her mouth. The parents noticed bleeding in the mouth and a missing tooth, and brought the child to a pediatric emergency department. A clinical assessment by the pediatric dental team confirmed the avulsion and since the tooth could not be located, a radiograph of the chest was obtained to rule out aspiration. The chest radiograph showed the tooth to be in the proximal jejunum.

Langerhans cell histiocytosis (LCH) is a rare proliferative disease of myeloid cells that can affect multiple organs and present with diverse clinical manifestations. The skeleton, skin and lymph nodes are commonly affected sites, while oral involvement is rare. LCH is currently classified by disease extent into single system and multisystem forms, and further categorized by risk organs. The purpose of this report is to describe the case of a six-month-old girl who presented with a chief complaint of feeding difficulties, premature eruption of the primary left maxillary second molar, expansion of the maxillary alveolar ridges and ulceration of the posterior maxillary oral mucosa. The diverse presentations of pediatric LCH in the literature are reviewed and the role of pediatric dentists and oral surgeons in helping to diagnose LCH is highlighted.

The coronavirus responsible for the current global pandemic, coronavirus disease 2019 (COVID-19), is well-known for its respiratory symptoms. The scientific community and frontline health care providers have been documenting a number of systemic manifestations, including clinical findings in the oral cavity. Among these findings, oral ulcerative lesions are becoming more prevalent in COVID-19 infection, with differing severities and presentations. Health care professionals should, therefore, be aware of the possible implications that COVID-19 has on the oral cavity to judiciously document, monitor and refer patients with ulcerative lesions to the appropriate medical and dental specialists for management when necessary.

Purpose: Fetal alcohol syndrome (FAS) results from the teratogenic effects of alcohol on the fetus. Oral manifestations are commonly found in FAS and contribute to the diagnosis. The purpose of this study was to provide a review of the literature and describe two cases of FAS.
Methods: Electronic searches were conducted in August 2021 in multiple databases. The cases of two children with FAS are reported.
Results: One hundred sixty-six articles were included. The oral features frequently reported were micrognathia, cleft palate, high arched palate, maxillary hypoplasia, prognathia and crowding. The first patient had systemic and orofacial changes, such as delayed physical and cognitive development, micrognathia, tooth impaction, malocclusion and enamel hypoplasia. The second child had cognitive, and speech and behavioral deficits, but no oral and dental abnormalities.
Conclusion: Dentists should be aware of clinical findings since they may take part in the diagnosis and management of FAS.

Purpose: To evaluate knowledge, perceptions and current practices regarding care-seeking behaviors and oral health in pregnant and non-pregnant adolescent and young adults, and to assess barriers to dental care during pregnancy.
Methods: An 18-question survey was distributed to patients in three tertiary hospital clinics in Columbus, Ohio, USA. Statistical analyses used chi-square and Fisher's exact tests, with significance at P <0.05.
Results: Of 227 respondents, 197 were female and about 30 percent were pregnant. The mean and median age was 17 years. Almost half were African American, 69 percent had public insurance and over 75 percent had one or two annual dental check-ups. Less than one percent indicated pregnant females should never go to the dentist, although 63 percent of pregnant respondents had not sought dental care while pregnant and less than five percent had been to the dentist in the six months prior to pregnancy. The most reported barrier to seek dental care was the patient being too busy.
Conclusions: Dental care among pregnant adolescents seems to be less utilized than their non-pregnant peers. The importance and safety of dental care during pregnancy are less understood among adolescents and young adults than in older, pregnant women. Most respondents, including males, stated that if a pregnant female has tooth pain, she should go to the dentist, but were unaware if materials used at the dentist were harmful to the baby. Interventions to improve knowledge and reduce barriers to dental care during pregnancy are needed for adolescents and young adults.

Purpose: To determine the effect of motivational interviewing (MI) to improve recall attendance after dental treatment under general anesthesia (GA).
Methods: The sample consisted of parents of randomly selected pediatric patients who had oral rehabilitation under GA at a children's hospital. An 18-item questionnaire that included demographics, education, language, country of birth and age was administered prior to the GA appointment. A five-minute MI phone call three months after the procedure and a second MI phone call after the first recall was conducted by a standardized interviewer. The primary outcomes were attendance at the six- and 12-month recall visits. Data were compared to a historical control group of participants who did not receive the MI phone call during the same date range.
Results: Of 100 patients, 72 participated in the first phone call and 51 participated in the second phone call. All children had public insurance. The estimated odds of a six-month recall visit for parents receiving a single motivational interview was 2.52 times (95 percent confidence interval [95% CI]=1.43 to 4.44, P =0.001) higher compared to the control. The estimated odds of a 12-month recall visit for parents receiving two motivational interviews was 2.40 times greater (95% CI=1.27 to 4.54, P =0.006) compared to the historical control.
Conclusion: A brief intervention using MI led to an improvement in attendance at both the six- and 12-month recall visits.
