Abstract
Aim EMONO is an equimolar mixture of oxygen and nitrous oxide. Studies investigating its anxiolytic effect mostly used behavioral scales for assessing anxiolysis in children during dental care. Observing this effect objectively in a pediatric population could be very interesting. Materials and methods We conducted a prospective uncontrolled monocentric pilot study to assess the equimolar mixture of oxygen and nitrous oxide (EMONO) anxiolytic effect in children during dental care by monitoring heart rate (HR) variation. Results A statistically significant difference could be highlighted between the HR before the dental care and after 5 minutes of EMONO inhalation, illustrating the anxiolytic effect of EMONO in an objective way. HR variation also suggests that the effect of EMONO seems to prevent a return to the initial level of stress, even during anesthesia. Conclusion All of the data in the literature confirm the essential role of nitrous oxide in pediatric dental care. Demonstrating the effectiveness of EMONO by objective criteria is necessary.

Abstract
Objectives This prospective observational study aimed to evaluate discomfort after extraction of deciduous teeth under local anesthesia. The primary objective was to describe the prevalence of post‐extraction pain (PEP), post‐extraction bleeding (PEB), post‐extraction biting injury (PEBI), and analgesic usage in children. The secondary objective was to define whether it is possible to determine a profile of patients or a type of extraction procedure predictive to PEP, administration of analgesics, PEB, or PEBI. Methods One hundred and twenty‐five children, aged 3–13 years, with indications of at least one deciduous tooth extraction, were included. Immediately after extraction, information concerning the patient and the extraction were collected. Eighteen to 32 hr after extraction, parents were called by phone to request reports concerning the onset and intensity of PEP assessed using the Wong‐Baker Faces (WBF) scale, the administration of paracetamol (acetaminophen) to their children, and the appearance of PEB and/or PEBI. Results Of the children, 37.3% reported PEP (WBF ≥2), but 23.3% of these children did not receive any analgesic drugs to help relieve pain. Pain appeared before 3 hr after extraction in 69% of the children. Higher incidences of PEP and usage of analgesics were found both in the group of children with unfavorable socioeconomic level compared to favorable level and in the group with pre‐operative pain compared to no pre‐operative pain (p < .05). Conclusions About a third of the children reported pain after extraction, but the instructions for pain relief were not followed by all parents. The socioeconomic level of the young patient and the pain felt during the extraction were important predictors of discomfort. Therefore, our study could help the dentist to provide information on predicted post‐operative discomfort and to allow suitable care depending on the patient's profile or procedure.

Abstract
Background Many studies were conducted to assess the benefit/risk of equimolar mixture of oxygen and nitrous oxide (EMONO), but evaluating the appetite associated to its use is now getting very little attention in the literature. The purpose of this study was to investigate the effects present, felt, and sought during care by the child related with the 50% nitrous oxide/oxygen (EMONO) sedation used in pediatric dentistry. Materials and methods All patients in consultation with the Dental Service of Nantes hospital and in need of EMONO were included in the study. In this prospective single-center study, the effects present, felt, and sought during care by the child and the assessment of EMONO appreciation were recorded. The presence of clear signs that the child was trying to extend the duration of the EMONO use was also sought. Results Only 62% of the patients were presented with an anxiolytic effect, and 40% relative analgesia. Both effects were associated in 33% of children. Over the 76 patients assessed, 12 attempted to extend the duration of the EMONO use (16%). After a bivariate statistical analysis, none of the variables appeared significantly associated with the extension of the EMONO use duration. Conclusion The significant proportion of patients who have prolonged the EMONO use seems to indicate a real attraction for nitrous oxide. This is the first study to evaluate nitrous oxide appreciation on a child. How to cite this article Prud’homme T, Allio A, Dajean-Trutaud S, et al.

Abstract
BACKGROUND Many studies were conducted to assess the benefit/risk ratio of EMONO (Equimolar Mixture of Oxygen and Nitrous Oxide) in France before it was authorized for use outside the hospital setting in 2009. The main objective of this project is to evaluate the effects sought and felt by children when EMONO is used in paediatric dentistry. The secondary objectives are to (i) evaluate the appreciation of EMONO by the children, (ii) characterize children who experience both analgesia and anxiolysis, (iii) evaluate children's appetite for EMONO and characterize children with a high appetite and (iv) evaluate the impact of the difference in practice among the French dental service university hospitals on anxiety. The maintenance of a framework for the safe use of this drug, whose place in dental care is fundamental, is essential. Twelve of the 16 French dental service university hospitals agreed to participate in this study. METHODS MEOPAeDent is an observational, descriptive, transversal study that aims to evaluate the effects sought and felt by children when EMONO is used in paediatric dentistry. Subjects requiring dental care under EMONO are recruited by 12 French dental service university hospitals. Patients aged from 3 to 15 years are recruited for the study when they visit a dental service of a French university hospital requiring dental care under EMONO. The investigator collects the necessary data from the child's medical records, from his own observations and from questions posed to the child and his/her parents. A survey is completed at the first and final sessions of dental care under EMONO. DISCUSSION This study will provide an evaluation of the effects of EMONO on the French paediatric population in need of dental care as well as evaluate the appetite for the use of this substance. The results will first be used to provide additional data that is essential to monitor the use of a product with an authorization to use it outside of hospitals from 2009 in France, confirm its safety for use and justify its framework of application.

Abstract
Neurofibromatosis type 1 (NF1) is a clinically heterogeneous neurocutaneous genetic disorder that manifests in the form of coffee-milk spots on the skin, Lish nodules, lentigines on the underarms and on the inguinal region, and neurofibromas. Orofacial manifestations of NF1 are common. Through a review of the literature, bone lesions, orthodontic and dental abnormalities, periodontal manifestations, and caries related to NF1 will be explored. In this study, we present a clinical case of a patient with neurofibroma in the oral cavity and infraocclusion of primary molars, as well as his dental management.

Abstract
Autism spectrum disorder (ASD) is a life-long heterogeneous psychiatric disorder, characterized by impaired social interaction and communication, and the presence of repetitive and stereotyped behaviors as well as restricted interests. These features have an impact on the oral health of these individuals: high risk of dental caries, poorer periodontal status, and bruxism are often described. Children with ASD often provide limited collaboration with medical procedures, particularly those considered invasive such as dental care. Children with ASD are prone to agitation, self-injury, and emotional dysregulation; they can also present hypersensitivity to sensory input. These features make it difficult for professionals to examine and treat children with ASD; they interfere with dental care and constitute a barrier to it. Most of them are treated under general anesthesia or sedation. Therefore, children with ASD present a challenge for the dental community. Adapted and specific strategies are required to allow individuals with ASD to go beyond the barriers of dental care. Different tools and techniques of evidence-based practice can be considered: visual pedagogy, behavioral approaches, and numeric devices can be used. Pediatricians have a key role in the oral care of children with autism. The aim of this article is to present the oral health associated with ASD, to set out the possible ways to improve oral health, to enable the practitioner to detect problems, to raise awareness, and to help patients and their families in their care pathway.

Abstract
This article is aimed at defining guidelines for dental surgeons to manage patients with warning signs of rare genetic diseases. Anomalies of tooth development may occur as an isolated condition or in association with other symptoms in syndromes. In many cases, dental anomalies may be the first manifestations of a genetic disease. The dentist can contribute to the diagnosis, and hence to an early treatment of this syndrome. When one or more dental anomalies are found, practitioners should refer patients to a genetic clinic or a specialized reference center to diagnose genetic diseases. Therefore, we provide, for the first time, a table of extra-oral signs that dental surgeons can look for in patients exhibiting heritable dental developmental anomalies.

Abstract
OBJECTIVES In this study we investigated pulpal blood flow (PBF) values and moving blood cell velocity (MBCV) curves recorded by laser Doppler flowmetry (LDF) for pulpal vitality diagnosis in general dental practice and to compare MBCV curves to standard diagnostic tests in traumatology. STUDY DESIGN LDF tests performed with the PeriFlux System 5000 were applied to vital and nonvital (endodontic treatment) teeth of healthy students (n = 52) and on 24 luxated teeth of patients. RESULTS The PBF values were not reproducible and no statistically significant differences were observed between vital and nonvital teeth. MBCV curves in contrast could distinguish between the 2 tooth types. Tests on luxated teeth showed that while 62.5% of MBCV curves correlated with conventional vitality tests, only 12.5% of MBCV curves could help in vital diagnosis. CONCLUSION When applied to luxated teeth, the MBCV curve appeared to be accurate when the standard vitality tests indicated a nonvital diagnosis.
