RESUMO
AIM: The aim of this study was to compare the cardiovascular effects [heart rate, oxygen saturation (SpO2 ), systolic and diastolic blood pressure] and the anaesthetic efficacy of intraosseous computerized anaesthesia (ICA) versus inferior alveolar nerve block (IANB) in Symptomatic irreversible pulpitis (SIP). METHODOLOGY: The study protocol was registered with ClinicalTrials.gov (NCT03802305). In a randomized, prospective clinical trial, 72 mandibular molar teeth with SIP were randomly allocated to conventional IANB injection (n = 36) or ICA injection (n = 36), both with 1.8 mL of 4% articaine with 1:100 000 epinephrine. The primary objective was to assess the cardiovascular parameters (heart rate, oxygen saturation, blood pressure) before, during and after the anaesthesia. The secondary objectives were to compare ICA with IANB for success and postoperative outcomes for up to 3 days. RESULTS: The maximum increase in heart rate in the ICA group was greater than in the IANB. Other cardiovascular parameters did not show differences throughout the clinical procedure. There were no statistically significant differences (p > .05) between groups for sex, age, or anxiety. The total success rate of ICA (91.43%) was significantly higher (p = .0034) than that of IANB (69.44%). CONCLUSIONS: This study establishes that ICA is safe and efficient in the first intention for the treatment of SIP of the mandibular molar.

INTRODUCTION: The concept of escape games dedicated to dental students is a new learning experience that has not yet been extensively explored. The aim of this pilot study was to assess the impact and perceived value of an endodontic-themed escape game as assessed by fourth-year dental students. METHODS: This study was conducted at the University of Nantes, Faculty of Dental Surgery using a cross-sectional pre- and post-test research design to assess students' changes in performance. Students in the fourth year of dental surgery study (n = 18) were divided in four groups for this study. The answers to the pre-test/post-test were 50 true/false questions. Moreover, a 20-question perception survey was given to all the participants after completion of the escape game. The study data were collected in May 2019. An unpaired t test analysed the mean differences between the groups. RESULTS: The results showed a statistically significant increase in post-test results (75.33% ± 10.17% of correct answers) compared to the pre-test results (67.33% ± 5.94% of correct answers) P < .05. Analysis of variance revealed that this change in score was not significantly different between the four groups. The students perceived the endodontic-themed escape game to be relevant. A one-sample t test indicated that students' mean (SD) perception 4.4 (0.7) was statistically significantly higher than the mean value of the evaluation scale P < .001. The students found this educational game to be a useful experience that helped them recall/apply knowledge whilst promoting teamwork. CONCLUSION: Therefore, this type of game can enhance students' learning and motivation.

Cathepsin C (CatC) is a cysteine protease involved in a variety of immune and inflammatory pathways such as activation of cytotoxicity of various immune cells. Homozygous or compound heterozygous variants in the CatC coding gene CTSC cause different conditions that have in common severe periodontitis. Periodontitis may occur as part of Papillon-Lefèvre syndrome (PLS; OMIM#245000) or Haim-Munk syndrome (HMS; OMIM#245010), or may present as an isolated finding named aggressive periodontitis (AP1; OMIM#170650). AP1 generally affects young children and results in destruction of the periodontal support of the primary dentition. In the present study we report exome sequencing of a three generation consanguineous Turkish family with a recessive form of early-onset AP1. We identified a novel homozygous missense variant in exon 2 of CTSC (NM_148170, c.G302C, p.Trp101Ser) predicted to disrupt protein structure and to be disease causing. This is the first described CTSC variant specific to the nonsyndromic AP1 form. Given the broad phenotypic spectrum associated with CTSC variants, reporting this novel variant gives new insights on genotype/phenotype correlations and might improve diagnosis of patients with early-onset AP1.

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. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03453411 registered 2 March 2018.

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.

RESUMO
BACKGROUND: Irreversible pulpitis is a highly painful inflammatory condition of the dental pulp. The recommended care is the removal of the coronal pulp (pulpotomy) for emergency treatment in multi-rooted teeth. However, achieving adequate analgesia in the case of mandibular molars presents many difficulties according to the dental literature. Intraosseous computerised anaesthesia (ICA), in particular, the QuickSleeper™ system, has already been demonstrated to be clinically efficient, but ICA is known to increase the heart rate reversibly in a manner that depends on the speed of injection. Therefore, accelerated heart rate was examined as a potential adverse effect of this injection. This trial aims to compare the cardiovascular effects and the anaesthetic efficacy of ICA versus inferior alveolar nerve block anaesthesia (IANB) in acute irreversible pulpitis of mandibular molars. METHODS: This study is a non-inferiority prospective, randomised, controlled, single-blind, two-group trial conducted at the Nantes University Hospital. The study design included two parallel arms at a ratio of 1:1 that will allocate seventy-two patients into two groups: the first group will receive QuickSleeper™ intraosseous anaesthesia; the second will receive an inferior alveolar nerve block before emergency treatment (pulpotomy). This study will include patients requiring emergency dental care under local anaesthesia with confirmed irreversible pulpitis in mandibular molars. The primary outcome is the time taken for the fluctuations in the cardiovascular parameters to return to baseline values during endodontic treatment in two different anaesthetic techniques. The secondary outcomes include efficacy of the technique, patient's pain perception before and after care, any post-operative effects, and factors associated with the delay of recovery of cardiovascular parameters between the 2 anaesthetic techniques. DISCUSSION: This trial will evaluate the factors associated with heart rate increase during local anaesthesia administration. The use of blood pressure and cardiovascular measurements can be considered an asset and additional safety in managing local anaesthesia. Detecting early signs of potential adverse events (AEs), particularly patients with certain medical conditions (cardiac rhythm disorders), would suggest caution in administering anaesthesia.

BACKGROUND: There is increasing evidence that periodontitis may affect male sexual health (MSH) (erectile function, production of sex hormones, and semen quality). However, a limited number of clinical studies demonstrate the association between MSH and periodontitis. OBJECTIVES: The aim of this study was to explore the relationship between periodontitis and MSF. MATERIALS AND METHODS: A comprehensive systematic review of the published literature in MEDLINE, PubMed, Scopus, Cochrane, EMBASE, and Web of Science databases from the earliest available online indexing year until October 2020 was performed, in accordance with the PRISMA guidelines. Keywords related to periodontitis were combined with words describing MSH. RESULT: A total of 19 studies were included and discussed in the systematic review. The number of study participants ranged from 53 to 197,136 individuals, aged between 18 and 95 years (mean age, 41.2 years). Six studies did not report the age of the participants. Out of nine studies, eight found a significant association between erectile dysfunction (ED) and periodontitis. Only three studies evaluated the association between sex hormone levels and periodontitis, and two of these studies showed that patients with periodontitis are expected to exhibit higher levels of testosterone. Finally, out of five studies, two demonstrated a significant association between semen quality and periodontitis. DISCUSSION: The findings in this review were limited by the quality and the few available studies. Results from the observational studies might have been affected by recall bias and confounded by cofactors. CONCLUSION: The results of this systematic review revealed a significant association between periodontitis and ED, although the responsible mechanisms remain unclear. The potential associations between sex hormone levels, semen quality, and periodontitis are yet to be demonstrated. In order to improve patient management, dentists and physicians need to be aware of the association between male sexual health problems and periodontitis.

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.

Scientific evidence validating the beneficial effect of loupes in preventing musculoskeletal disorders is very scarce. The aim of this study was to assess the impact of dental loupes on dental students' posture during a preclinical restorative dentistry course. Using a randomized crossover design, this study was conducted at the School of Dentistry, University of Nantes, France, in 2017. Forty students in their second year of dental study were randomly divided into two groups of 20 each: group A used loupes, whereas group B did not. The week after, students reversed configurations (each subject served as his or her own treatment and control group). Students were video-recorded during cavity preparation. Trunk, head and neck, and upper arm positions were analyzed using continuous scores based on the modified Posture Assessment Instrument. Additionally, cavities were rated, and students completed a questionnaire on their perceptions of the loupes. On a scale on which lower scores indicated better posture, the results showed significantly higher posture ergonomic scores per minute for students without loupes (146.3±6.64 points/min) than with loupes (123.2±6.77 points/min; p<0.05). The majority of the students (32/39, 82%) showed improvements in ergonomic postures with the use of loupes. Trunk, head, and neck were positively impacted by the use of loupes, but not the upper arms. Cavity preparations were not improved by the use of loupes. The questionnaire revealed negative aspects (pain and difficulty adapting) but underlined the perceived positive impact on posture. This study documented the ergonomic advantages and challenges of introducing magnification near the beginning of the dental training program.

Runt-related transcription factor 2 (RUNX2) is well-known for its role in bone development and tooth morphogenesis. Most RUNX2 mutations described in the literature result in loss-of-function mutations of RUNX2 responsible for cleidocranial dysplasia, an autosomal dominant disorder. We describe here the oro-dental phenotype of four patients of a unique family with a 285â¯kb duplication including the entire sequence of RUNX2, likely responsible for three functional copies of the gene, leading to an increased RUNX2 dosage. Several dental anomalies of number (hypodontia or oligodontia), morphology (microdontia, radiculomegaly, taurodontism or dens invaginatus) and tooth position (rotation) were found in these patients.

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.

RESUMO
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.

RESUMO
Localized aggressive periodontitis (LAP) in child involving primary dentition is a rare disease. The main characteristics of LAP are deep periodontal pockets, bone loss, tooth mobility, and, sometimes, spontaneous tooth loss. The LAP involves only some specific teeth. Glanzmann's thrombasthenia (GT) is a rare autosomal recessive bleeding disorder. The paper's aim is to present the case of a 5-year-old girl with GT presenting LAP, and discuss her clinical management.

RESUMO
The aim of this paper is to present the long-term follow-up of one paediatric zirconia crown on a deciduous molar. Preformed crowns are part of the armamentarium in paediatric dentistry. In recent years, aesthetic alternatives to preformed metal crowns have been developed, first preveneered crowns and then zirconia crowns. This paper describes the restoration of a primary molar with a zirconia crown (EZ-Pedo, Loomis, California, USA) in an 8-year-old boy. In this clinical case, the protocol for the implementation and maintenance of zirconia crowns is detailed. The patient was followed up for 29 months until the natural exfoliation of his primary molar. The adaptation of the zirconia crown, the gingival health and the wear on the opposing tooth were considered. In this case, the paediatric zirconia crown allowed sustainable functional restoration while restoring a natural appearance of the tooth.

Enamel opacity on anterior teeth can be prejudicial for the aesthetic appearance of affected patients. Patients with molar incisor hypomineralisation, for example, present opacities that can range from discrete white mottling to extensive yellow-brown discolourations. They can request a treatment to improve their aesthetic conditions. Many techniques have been considered to manage this condition. Wright developed a technique called etch-bleach-seal, which showed promising results for the management of anterior enamel opacities. The aims of this report are to present this technique and to analyse its benefits and inconveniences.
