    Abstract Anxiety/pain is a combined experience that can hinder dental treatment in children and lead to the development of negative behaviours in any form of surgical treatment. Hypnosis is a suitable option with which to reduce anxiety and pain during dental treatment. In this study, we aimed to evaluate the efficacy of hypnosis compared to the tell/show/do technique for the reduction of anxiety and pain as measured by Face, Legs, Activity, Crying, Consolability (FLACC) scale in children undergoing pulpotomies. We performed a randomized and controlled clinical trial involving 60 children aged 5 to 7 years without previous dental experiences but with clinical and radiographic indications for pulpotomy in the primary mandibular right or left first or second molar. The children were divided into two groups: a control group (treated by conventional behaviour management techniques) and an experimental group (treated by hypnosis). The FLACC scale was used to evaluate anxiety/pain during preoperative, transoperative and postoperative pulpotomy treatment; we also analysed variations in heart rate and skin conductance. The trial was registered at ClinicalTrials.gov (NCT03739346). Statistical analysis was performed in R Studio version 1.2.1335. The FLACC scale was significantly lower in the experimental group (

    Abstract The study aimed to perform a systematic scoping review with the need of exploring the actual clinical applications of the chloramphenicol-tetracycline-ZOE antibiotic paste (CTZ) as a lesion sterilization tissue repair (LSTR) therapy agent. Following a scoping framework suggested by Arksey and O'Malley, relevant articles (randomized controlled trials, literature reviews, observational studies, in vitro studies, and clinical case-series reports) published over the last 15 years (in English, Spanish, or Portuguese languages) were identified and retrieved from five internet databases: PubMed, Embase/Ovid, Cochrane Library, Google Scholar, and EBSCO. By title and abstract screening and after removing duplicates, 11 articles were finally included in the present scoping review: five randomized/non-randomized clinical trials, five in vitro studies, and one case-series report. According to the collected information, there were no differences between CTZ paste and conventional pulpectomy, antibiotic pastes, and intracanal filling materials, considering the clinical, radiographic, antimicrobial activity, and periapical tissue biocompatibility outcomes. CTZ has shown excellent rates of clinical success and good radiographic results, with adequate antimicrobial effects; however, its biocompatibility has been put into doubt. Contemporary pediatric dentists should carefully consider the CTZ paste as an alternative endodontic approach for pulpally involved primary molars, with the advantages of being simple and fast, and taking into account the limitations of instrumental pulpectomy such as the microbiological and morphological complexity of primary root canals.

    Abstract A study was conducted to evaluate the success rates of bypassing or removing fragments of instruments that had fractured within the roots of mandibular molars using a HBW Ultrasonic Ring. Forty extracted first permanent mandibular molars with root canal curvature were included. The teeth were distributed randomly into four groups according to the type of instrument and the root canal third where they had fractured. The success rate for removal of instrument fragments was 100% for both of two stainless steel groups, 90% for a nitinol middle third group, and 80% for a nitinol apical third group. The mean time required for instrument removal was around 40 min. The HBW Ultrasonic Ring showed acceptable experimental results for retrieval of broken instrument fragments.

    Abstract Background: Acrylic resins used in dental and biomedical applications do not have antimicrobial properties, their surface is susceptible to colonization of microorganisms.
    Objective: The aim of this study was to evaluate the antibiofilm properties of silver nanoparticles (AgNPs) deposited in a polymethyl methacrylate (PMMA) surface against a Staphylococcus aureus biofilm.
    Methods: The PMMA was impregnated with AgNPs by using the in-situ polymerization method. To determine the solubility of the incorporated silver (Ag+) atomic absorption spectrophotometry was used (AAS) at 24 h, 48 h, 7 days, and 30 days. Thirty specimens of PMMA with AgNPs and without NP (control group) were assembled in the CDC Biofilm Bioreactor system with a cell suspension of S. aureus. The specimens were removed at 6, 12, 24, 48, and 72 h to determine the viability profile and quantify the Arbitrary Fluorescence Units (AFU).
    Results: The AgNPs showed an irregular and quasispherical shape with an average size of 25 nm. AAS analysis demonstrated a low solubility of Ag+. The formation of the S. aureus biofilm increased as the evaluation periods continued up to 72 h. The experimental group showed poor growth, and a decrease in the intensity of the fluorescence demonstrated a statistically significant inhibition of the formation of the biofilm (P < 0.05) in relation to the control group at 6, 12, 24, 48, and 72 h.
    Conclusion: AgNPs incorporated into PMMA decreased the growth and maturation of S. aureus biofilm.

    Abstract Background: Surface coating technology can assist fixed appliances by reducing friction, improving antibacterial characteristics, and increasing corrosion resistance. The application of functional coatings composed of graphene onto the surfaces of orthodontic brackets and archwires has been shown to enhance their mechanical qualities. The objective of the current study was to carry out a scoping analysis of published recent evidence on the utilization of graphene as a covering material in metallic orthodontic accessories, such as brackets and archwires; Methods: A scoping review was undertaken following the PRISMA-ScR guidelines. PubMed, Embase, the Cochrane Library, Dentistry and Oral Science Source, and Google Scholar were searched between 2003 and 2023; Results: In total, 38 potential references were detected, from which 10 were selected for this review. These articles addressed the benefits of the application of graphene-oxide functional coatings onto the surface of archwires and brackets during fixed orthodontic treatment. Orthodontic graphene-oxide-based coatings provide improved surface characteristics (e.g., reduced friction and anticorrosive effects), antibacterial capabilities, and biocompatibility. These characteristics can increase the effectiveness of orthodontic therapy, improve patient comfort, and lower the likelihood of problems; Conclusion: Orthodontists should be aware of and comprehend the prerequisites for using graphene-oxide-coated archwires and brackets to fulfill needs throughout their clinical practice.

    Abstract This review aimed to summarize the preventive, non-restorative and restorative minimal intervention dentistry (MID) interventions for managing dental caries during the primary dentition stage, after selecting the highest quality evidence. A comprehensive literature search for relevant studies was performed in PubMed (MEDLINE), Embase, Cochrane Library and Google Scholar, published between 2007 and 2022. Only clinical randomized controlled trials, clinical guidelines with literature review, systematic reviews and meta-analyses conducted in the primary dentition were included. One hundred fifty-three MID-associated references were found, and 63 of them were considered for the present review. Of these, 24 were clinical randomized controlled trials, 21 were systematic reviews, 3 umbrella reviews and 11 practice guidelines with a literature review. The retrieved evidence was divided into (and discussed) three general caries management strategies: (i) carious lesion diagnosis and individual risk assessment; (ii) preventive measurements and non-cavitated lesions management; and (iii) cavitated lesions management. MID is an attractive alternative management that promotes prevention rather than intervention to achieve a long-lasting oral health in young children through easy and cost-benefit preventive, non-invasive, minimally invasive or conservative invasive restorative measures. This philosophy of management is suitable for treating young children, considered friendlier and less anxiety-provoking than traditional methods.

    Abstract Objective: Evidence supports the local application of non-steroidal antiinflammatory drugs such as dexketoprofen trometamol (DXT) for pain management, but little is known about the potential antinociceptive effect of chlorhexidine gluconate (CHX) and its possible synergistic effect when combined with DXT. The aim of this study was to evaluate the local effect of a DXT-CHX combination using isobolographic analysis in a formalin pain model in rats.
    Materials and methods: Briefly, 60 female Wistar rats were used for the formalin test. Individual dose effect curves were obtained using linear regression. For each drug, the percentage of antinociception and median effective dose (ED50; 50% of antinociception) were calculated, and drug combinations were prepared using the ED50s for DXT (phase 2) and CHX (phase 1). The ED50 of the DXT-CHX combination was determined, and an isobolographic analysis was performed for both phases.
    Results: The ED50 of local DXT was 5.3867 mg/mL in phase 2 and for CHX was 3.9233 mg/mL in phase 1. When the combination was evaluated, phase 1 showed an interaction index (II) of less than 1, indicating synergism but without statistical significance. For phase 2, the II was 0.3112, with a reduction of 68.88% in the amounts of both drugs to obtain the ED50; this interaction was statistically significant (P < .05).
    Conclusion: DXT and CHX had a local antinociceptive effect and exhibited synergistic behavior when combined in phase 2 of the formalin model.

    Abstract Aims: This study aims to provide a comprehensive review and case study about the advantages and disadvantages of the application of digital technologies in presurgical orthopedics in newborns/infants with cleft lip and palate (CLCP). Positive changes in the nasal anatomy, maxillary arch, and cleft width could be achieved.
    Methods: Three representative cases of newborns/infants with CLCP were managed using the presurgical newborn/infant orthopedics (PSIO) approach. The patients were diagnosed and treated. Detailed descriptions of the impression procedures and PSIO appliance construction and placement were provided for each case.
    Results: Case 1 utilized traditional impression techniques, Case 2 employed a semi-digitalized approach with intraoral digital scanning, and Case 3 utilized a completely digitalized method for appliance construction. Positive changes in maxillary arch dimensions and cleft width reduction were observed in all cases.
    Conclusions: The management of CLCP in newborns and infants poses a complex challenge with profound implications. The PSIO approach not only facilitates reconstructive surgery but also enhances overall quality of life. Digital tools, like specialized optical scanners and 3D printing, revolutionize the PSIO process, making it more efficient and patient-friendly. Clinical benefits include improved facial morphology, esthetics, feeding, speech, and optimized future surgical results. Despite ongoing efficacy debates, global adoption as the initial surgical approach underscores its value. The integration of digital technologies offers new hope for patients and families, promising a brighter future for those affected by this congenital condition.

    Abstract Objective: To summarize the clinical/radiographic outcomes from the evidence of studies published since 1988 on different DPC agents applied on vital pulp-exposed primary teeth.
    Methods: The following electronic databases were searched: PubMed, Embase, Cochrane Library, Dentistry and Oral Science Source, and Google Scholar. Inclusion criteria were randomized controlled trials (RCTs) published between January 1988 and December 2019, with at least 6 months of follow-up, comparing the clinical and radiographic success rates of two or more DPC agents applied in primary teeth with cariously and non-cariously exposed pulp.
    Results: Initial searches identified 83 potentially relevant studies on DPC in primary teeth. Sixty-four of these studies were excluded, whereas 19 articles satisfied the inclusion criteria and were retrieved in full text for data extraction and a methodological quality assessment. Finally, 12 of these articles were included in the systematic review. Low and moderate risks of bias were observed. Overall, DPC clinical and radiographic success rates among the selected studies ranged between 53% and 100%.
    Conclusions: For DPC in primary teeth, this systematic review found that diverse new biologically and compatible agents with promising success rates are currently available for paediatric dentistry practitioners. There is no evidence that justifies discarding the judicious use of DPC procedures in primary teeth.

    Abstract Objective: The objective of this study was to determine the age-related anatomical changes that take place at the cementodentinal junction (CDJ).
    Methods: Eighty-four teeth were extracted; 42 samples came from patients ranging in age from 18 to 30 years, and 42 came from patients aged from 40 to 60 years. Upper and lower and anterior and posterior teeth were included. Longitudinal slices were made, and 1% toluidine blue was used to stain all the samples prior to microscopic examination. Anatomical landmarks (apical foramen [AF], apical vertex, and cementoenamel junction) in the apical third were identified, and a pre-calibrated software package was employed to take digital measurements. Statistical analysis was performed by means of the Wilcoxon rank-sum test.
    Results: The data obtained showed that there were anatomical variations in the apical third in the older patients and that these changes were related to the age of the patient. Narrower root canals and smaller CDJ diameters were found in older patients' samples.
    Conclusion: The results of this study suggest that instrumentation and obturation should take place 1 mm from the AF in older patients, and not 0.5 mm, as is usually recommended.
