BACKGROUND: Molar-incisor hypomineralization (MIH) is a developmental enamel defect characterized by opacities from white to brownish color. A suspected multifactorial etiology has been suggested, whereas psychological factors during pregnancy have only been limitedly analyzed. AIM: We assessed the association between stress, depression, and anxiety in pregnancy and the presence of MIH in children at a later age. DESIGN: Using a cross-sectional Web-based questionnaire, we included 384 mothers who had children aged 6 and 12 years from Pasto, Colombia...

BACKGROUND: Temporomandibular disorders (TMD) do not only occur in adults but also in adolescents, with negative impacts on their development. AIM: To propose a predictive model for TMD in adolescents using a decision tree (DT) analysis and to identify groups at high and low risk of developing TMD in the city of Recife, PE, Brazil. DESIGN: This cross-sectional study was conducted in Recife on 1342 schoolchildren of both sexes aged 10-17 years...

BACKGROUND: In order to generate a normal set of teeth, fine-tuning of Wnt/β-catenin signaling is required, in which WNT ligands bind to their inhibitors or WNT inhibitors bind to their co-receptors. Lrp4 regulates the number of teeth and their morphology by modulating Wnt/β-catenin signaling as a Wnt/β-catenin activator or inhibitor, depending on its interactions with the partner proteins, such as Sostdc1 and Dkk1. AIM: To investigate genetic etiologies of dental anomalies involving LRP4 in a Thai cohort of 250 children and adults with dental anomalies...

BACKGROUND: Eccentric instruments have been proposed as more effective and less time-consuming for endodontic instrumentation. AIM: To compare biomechanical outcomes of different instrumentation systems and time undertaken for instrumentation in resin prototypes. DESIGN: Sixty standardized prototypes of mandibular second primary molars were instrumented according to the following systems: K-files, ProTaper Next (PTN), XP-endo Shaper (XPS), XP-endo Finisher (XPF), XP-Clean (XPC), and Sequence Baby File (SBF; n = 10/each)...

BACKGROUND: Prior literature highlights the importance of local anesthesia (LA) for stainless steel crown (SSC) preparation and placement. Nevertheless, the effectiveness of a eutectic mixture of local anesthesia (EMLA), a topical anesthesia, for this purpose remains unexplored. AIM: The study evaluated the effectiveness of two EMLA application methods during SSC preparation and placement. DESIGN: Eighty-four children between 4 and 8 years of age were randomly allocated to three intervention groups...

BACKGROUND: Maxillary central incisors (MCI) are the third most impacted teeth. Timely multidisciplinary management is indicated as unerupted incisors can cause functional- and appearance-related distress. AIM: To assess the patient journey for children with unerupted MCI, including referral, clinical assessment, surgical management and follow-up treatment, and highlight areas for improvement, as well as identify factors impacting orthodontic treatment burden (OTB)...

BACKGROUND: The Abeer Children Dental Anxiety Scale (ACDAS) source language was developed and validated in an English-speaking country in the UK to measure dental anxiety among children. The ACDAS also included the child's cognitive assessment, as well as feedback from the parent or the legal guardian and a dental health professional (DHP). This is the first study to validate the application of the ACDAS in Malay or Bahasa Melayu for children aged 6-16 years. AIM: To assess the Malay-translated version of the ACDAS, postadaptation into the local context and validation by the content and construct experts...

BACKGROUND: Clinical practice guidelines (CPGs) enhance health care and aid clinicians' decisions. AIM: To evaluate the quality of clinical guidelines in paediatric dentistry using the AGREE II tool. DESIGN: PubMed, EMBASE, Scopus, LIVIVO, Lilacs, international guidelines websites, scientific societies, and gray literature were searched until September 2021. We included paediatric dental clinical guidelines and excluded drafts or guidelines for patients with special needs...

BACKGROUND: Molar-incisor hypomineralisation (MIH) is a prevalent condition, and how it is managed varies greatly between professional groups. AIM: To explore, and compare, the UK and Australian general dental practitioners' management of MIH in children. DESIGN: Face-to-face (remote) semistructured interviews were undertaken, using country-specific topic guides. Participants were purposively sampled and recruited through national conferences and research networks (eviDent Foundation and Northern Dental Practice Based Research Network)...

BACKGROUND: The prevalance of dental caries in children in Qatar is high, which necessitates preventive efforts. AIM: To identify the sociodemographic and behavioural correlates of dental caries in the primary dentition of children 4- to 8-year-olds in Qatar. DESIGN: Weighted data from the Qatar Child Oral Health Survey 2017 were analysed for caries prevalence (dmft>0) and experience (dmft). Sociodemographic and behavioural variables were also drawn from the survey...

BACKGROUND: Ectopic eruption of the maxillary first permanent molar is a local disturbance that affects the development of the occlusion. AIM: To evaluate the occurrence of self-correction of maxillary first permanent molar's ectopic eruption and its predictive factors. DESIGN: Five electronic databases and part of the gray literature were investigated. The risk of bias was assessed using the Newcastle-Ottawa scale and the certainty of evidence using the GRADE tool...

BACKGROUND: Molar incisor hypomineralization (MIH) is prevalent worldwide and is a challenge for clinicians who provide oral care to children. Molar incisor hypomineralization has been considered a multifactorial disturbance that results from a combination of environmental and genetic factors. AIM: This scoping review followed the Joanna Briggs Institute protocol and aimed to identify the available evidence of the genetic influence on the etiology of MIH. DESIGN: The search strategy was conducted in multiple databases, including PubMed, BVS, Embase, Web of Science, and Scopus...

BACKGROUND: Few extended studies have explored oscillating-rotating (O-R) toothbrush efficacy in young children. AIM: To compare the efficacy between O-R and manual toothbrushes in reducing plaque and gingivitis after 4 weeks in children. DESIGN: This was a randomized, parallel-group, examiner-blind, clinical trial. In two 50-subject cohorts (3-6 years, primary dentition, parental brushing; 7-10 years, mixed dentition, self-brushing), subjects used Oral-B Kids O-R toothbrush per manufacturer's instructions or Paro Junior manual toothbrush in a customary manner...

BACKGROUND: There is no consensus on which molar incisor hypomineralization (MIH) indices are more suitable for epidemiological surveys. AIM: To compare the operational aspects and diagnostic ability of the MIH index (simplified/MIH_s and extended/MIH_e) with the MIH-Severity Scoring System (MIH-SSS) in classifying and diagnosing MIH. DESIGN: This cross-sectional study assessed the indices in a homogeneous group of 680 6- to 10-year-old schoolchildren in Bauru, Brazil, who had at least one first permanent molar, ensuring consistent conditions...

BACKGROUND: School-based oral health education has emerged as one of the most effective methods to instill a positive attitude toward oral health in children.

The British Society of Paediatric Dentistry's (BSPD) first policy document on dental neglect was published online in 2009. It proposed a new original definition of dental neglect, discussed the identification of dental neglect and recommended adopting a tiered response, with three stages of intervention according to level of concern. Furthermore, it detailed how the dental team should both contribute to the child protection process and implement wider measures to safeguard and promote children's welfare. Since 2009, these concepts have been widely adopted in the UK and beyond...
