RÉSUMÉ
BACKGROUND: Because of controversial results from clinical studies comparing different dental local anesthesia methods in children, the primary objective of this randomized, split-mouth, crossover, controlled trial was to compare pain intensity during local anaesthesia (LA) performed with a computer-controlled LA delivery system (C-CLADS) versus a conventional syringe (CONV). Secondary objectives included comparisons during dental treatment. METHODS: Participants (4-8 years) with tooth pair requiring similar treatment were recruited from five French hospitals. The right primary molar, which was treated at the first visit, was randomly allocated to one of the anaesthesia groups (either intraosseous with C-CLADS or infiltration with CONV), whereas the contralateral molar (treated at the second visit) was assigned to the other group. Pain intensity and behaviour outcomes, assessed with the Faces Pain and Venham revised scales, respectively, were compared between groups using Proc mixed. Stratified analyses were performed on dentition and location. RESULTS: Among 107 participants, the analysis revealed reduced pain perception during LA in the C-CLADS group compared with the CONV group (-0.72, 95% CI: -1.43, -0.006), but not during dental treatment. Stratified analyses showed that this effect was observed only in primary dentition (p = .006) and mandibular molars (p = .005). Behavioural issues were fewer in the C-CLADS group than in the CONV group (p = .05) only during injection. CONCLUSION: C-CLADS emerged as the preferable system in primary dentition.

(1) Background: Obstructive sleep apnea (OSA) affects approximately 1% to 5% of children. To date, the main pathophysiological factor is adenotonsillar tissue hypertrophy. As many respiratory viruses can persist in secondary lymphoepithelial organs after upper airway infection, the objective of this systematic review was to investigate the link between history of viral infections and the risk of pediatric OSA. (2) Methods: Corresponding references were searched electronically (PubMed [MEDLINE], Cochrane Library and Scopus) until 21 November 2022. Prospective or retrospective cohorts, evaluating the children suffering from OSA with history of viral infections and comparing them with children with no history of viral infections written in English, were included. Four independent reviewers selected studies, extracted data, and evaluated the risk of bias using ROBINS-I. (3) Results: Of 1027 potentially eligible articles, four studies (one retrospective, two prospective cohorts and one case-control) were included. (4) Conclusions: Exposure to lower airway infections may precede the diagnosis of pediatric OSA suggesting that respiratory viruses may play a mechanical role in the development of pediatric OSA. Further research is required to improve our understanding of the role of viral infections. Registration: PROSPERO CRD awaiting.
RÉSUMÉ
INTRODUCTION: The objective of this study was to assess an original learning intervention to train students and paediatric dentistry teachers in radiographic diagnostic accuracy of pulpo-periodontal complications in primary molars. MATERIALS AND METHODS: The learning intervention was based on 250 different randomly ordered radiographs of primary molars within three quizzes (A, B and C) for 5 sessions (S): quiz A (50 X-rays), B and C (100 X-rays) were, respectively, completed in S1 to assess the extent of agreement with 5 experts' diagnoses, in S2 and S3 (B at days 8 and 23) and in S4 and S5 (C at days 90 and 105). During S1 and at the end of S3 and S5, the participants (48 students and 16 teachers) were informed of correct diagnoses. A satisfaction questionnaire was completed by all the students. Alongside the descriptive analyses, generalised linear mixed model (GLMM) analyses assessed the odds of participants' correct diagnosis over the study duration. RESULTS: At S1, the odds of diagnostic accuracy among students were significantly lower than those among the teachers. After receiving feedback at S1, GLMM analyses showed that among all the participants, accuracy improved over time with the odds of correct diagnoses higher in S2-5 than in S1; and there were similar increases across sessions between teachers and students, except in S3, where the improvement among teachers tended to be greater than that among the students. All students were satisfied though one-third reported that quizzes with 100 radiographs felt too long. CONCLUSION: The online case-based learning was a good training format for dental education.

BACKGROUND: Worldwide, numerous surveys have investigated practices and knowledge about caries management in adults, but few are available for children. AIM: The present cross-sectional survey aimed to assess the restorative thresholds (RTs) in primary and permanent molars in children used by a population of dentists treating children and practicing in France. DESIGN: The study population consisted of French dentists treating children (Fr-DTCs) who were registered in the French Society of Pediatric Dentistry (n = 250). A specific questionnaire was developed. Descriptive and statistical analyses were performed. RESULTS: Response rate was 80.4% (n = 201). Considering that an appropriate RT is at the stage of a moderate lesion (occlusal: International Caries Detection and Assessment System 4; approximal: lesion involving the external third of dentine), more than 50% of respondents showed a tendency for iatrogenic treatment, except for occlusal carious lesions in primary molars. Inappropriate invasive strategies were more often reported for occlusal lesions in permanent than primary molars. Moreover, for both molar types, these inappropriate RTs were more often chosen for approximal than occlusal lesions. CONCLUSIONS: The present survey suggested that Fr-DTCs tend to overtreat in terms of caries management in both primary and permanent molars.

BACKGROUND: Questionnaire surveys have been undertaken worldwide to investigate practices and knowledge related to deep carious lesion (DCL) management in permanent teeth, and there is a lack of data in primary teeth. AIM: A cross-sectional questionnaire survey was undertaken to describe the management strategies for DCL of vital primary teeth, focusing on the different caries removal techniques, among dentists practicing pediatric dentistry (DPPDs) in France. Their behavior was compared to members one registered to European Academy of Pediatric Dentistry (EAPD). DESIGN: A questionnaire was electronically administrated (2018-2019) to members of the Collège des Enseignants en Odontologie Pédiatrique (CEOP), the Société Française d'Odontologie Pédiatrique (SFOP), and the EADP. Descriptive and statistical analyses were performed. RESULTS: Response rate was, respectively, for CEOP, SFOP, and EAPD about 74%, 29%, and 15%. About half of the respondents (53%) would perform a complete caries removal into one step when 12% would indicate a stepwise technique: 68% of the DPPDs practicing in France would perform complete caries removal in one step when the preferred option in the other EAPD members was the selective excavation (44%) (P < .001). CONCLUSIONS: Complementary education of French dentists in the domain of caries management appears necessary regarding current recommendations.

The study aimed to compare the efficacy of three caries removal techniques-complete caries removal (CCR), selective caries removal (SCR), and stepwise caries removal (SWR)-for deep carious lesions in vital temporary teeth by conducting a systematic review and meta-analysis of randomized controlled trials (RCTs). Electronic databases (PubMed [MEDLINE], Cochrane Library, EMBASE) were searched for corresponding references up to 31 May 2019. Possible outcomes were pulp exposure, pulpo-periodontal complications, or restorative failures. Three reviewers independently selected studies, extracted data, and assessed the risk of bias using RoB 2. Meta-analyses for intention-to-treat and per-protocol scenarios were performed using Revman5. Of 1374 potentially eligible articles, ten relevant references corresponding to eight studies were included. Pooled results showed decreased risk of pulp exposure after SCR (OR: 0.10, 95% CI [0.04, 0.25]) or SWR (OR: 0.20, 95% CI [0.09, 0.44]), compared with CCR. There was a higher risk of composite restorative failure (OR: 2.61, 95% CI [1.05, 6.49]) using USPHS criteria, after SCR compared with CCR only in intention-to-treat analysis. Risk of clinical or radiographic failure of pulpo-periodontal complications was unchanged when compared with SCR and CCR or SWR. SCR and SWR may result in lower pulp exposure risk than CCR. RCTs with lower risk of bias, higher power, and longer follow-up are required to choose between these three caries removal techniques for deep carious lesions in vital temporary teeth.

BACKGROUND: Guidelines in pediatric restorative dentistry recommend the use of preformed pediatric stainless steel crowns (SSCs) in cases of severe tooth decay of at least two surfaces. This clinically effective and safe restorative option is frequently refused by parents for esthetic reasons; they prefer conventional restorations using esthetic filling materials (composites, glass ionomer) if lesion severity limited to two surfaces permits. Recently, manufacturers have proposed esthetic preformed pediatric zirconia crowns (ZCs) but these have been assessed in only two randomized clinical trials (RCT) with follow-ups of 6 and 12 months. Only one of these RCTs was carried out on primary molars to test ZCs (NuSmile ZR) without a groove in its inner surface. The primary objective of this proposed RCT is to assess the effectiveness of ZCs compared with SSCs. Our hypothesis is that the effectiveness of ZCs will be equivalent to that of SSCs. METHODS: In this split-mouth, 2-year RCT, pairs of primary molars in 101 child participants will be randomized and restored with SSCs (ESPE, 3M) and ZCs (EZCrowns, Sprig Oral Health Technologies) characterized by grooves on their inner surface. Primary molars will first be allocated to SSCs, and 1 to 2 weeks later the other primary molar of the same pair will be restored by ZC. The primary outcome is the success defined by the "absence of major clinical and radiographic failure" (e.g., pain, pulp infection, dental abscess or periradicular pathology visible on radiographs). The secondary outcomes include the retention and fracture rates, the gingival condition, the wear of the antagonist of the treated teeth, as well as both parental and child satisfaction. DISCUSSION: This study will investigate two types of preformed pediatric crowns for the management of severe decay on primary molars. The results may help practitioners choose the better therapeutic option and to explain to parents the advantages and disadvantages of these two therapies. TRIAL REGISTRATION: NCT03296709 . Registered on 27 September 2017.

BACKGROUND: Different aesthetic preformed crowns (APC) are proposed to restore decayed and damaged primary teeth because the stainless steel crowns (SSCs) do not satisfy parents concerned about aesthetic. AIM: The objective was to evaluate the clinical effectiveness of all types of APC for restoring primary teeth compared with conventional filling materials or other types of crowns. DESIGN: Relevant articles were searched in electronic databases of PubMed via MEDLINE and the Cochrane central register of controlled trials. Two review authors independently assessed the risk of bias in the included articles and extracted data. RESULTS: From 555 potentially eligible articles, seven relevant articles were included. The overall risk of bias was high for all the studies. SCCs cannot be replaced by APC, such as the open-faced SSCs and the pre-veneered SCCs, for restoring badly decayed primary molars. Zircon crowns were assessed only in primary incisors and compared with pre-veneered SCCs and resin composite strip crowns. After a follow-up of only 6 months, Zircon crowns gave significantly better results than the others with regard to gingival health and crown fractures. CONCLUSION: Due to the small number of RCTs on this topic and their risk of bias, future RCTs should be carried out in primary teeth.
