Purpose: To determine the interests of Google users from different countries about pacifier-related information over time, through a quantitative and qualitative analysis.

Methods: This infodemiology longitudinal retrospective ecological study investigated pacifier-related computational metadata from 22 countries using Google Trends platform. Initially, Relative Search Volume (RSV) time series data and their respective main queries were collected employing the topic "pacifier - subject" as the search strategy from January 2004 to June 2024, considering all categories. Data were then analyzed through seasonal decomposition to determine the trend, seasonal, and residual components of the collected time series using Python 3 programming libraries in a Google Collaboratory interface. Additionally, Mann-Kendall tests were performed to access the significance level of trends observed from the seasonal decomposition. Finally, the queries were qualitatively evaluated to identify the main subjects related to users' interests. Statistical significance was determined with p values < 0.05.

Results: In general, RSV time series curves exhibited upward trends in all analyzed countries over the years, with significance levels demonstrated by the Mann-Kendall tests. Moreover, queries often centered around types of pacifiers, encompassing searches specifically for certain commercial brands. Some searches concerning newborn and baby care were also observed, particularly highlighting breastfeeding practices.

Conclusion: Google users have shown an increasing interest in pacifier-related topics. These data can help understand the needs and concerns of parents and caregivers regarding pacifier use, ultimately supporting the development of effective educational strategies.

Aim: The aim of this study is to assess the knowledge, and treatment of MIH among dentists in Jordan.

Methods: An online questionnaire using Google Forms was sent to the dentists who were registered with the Jordan Dental Association and worked in Jordan through social media groups. The questionnaire consisted of three sections, sociodemographic characteristics, the knowledge of dentists about the aetiology, diagnosis, and prevalence of MIH, and treatment options and barriers for treating MIH. Descriptive statistics with chi-squared test was used, and level of statistical significance was set to 5%.

Results: A total of 388 dentists had responded to the questionnaire (response rate 24.25%), (80.7%) reported that they have come across MIH cases during their practice. Yellow/brown demarcations were reported as the most common presentation of MIH (45.6%). All paediatric dentists were confident in diagnosing MIH, this was statistically higher than that reported by general dentists (56.8%) and dentists of other specialities (60.2%), P = 0.000. Pre-formed metal crowns were the treatment of choice for (57.2%) of participant, followed by composite restorations (52.3%). Child behaviour (56.2%), and late acknowledgment of the defect by the parents (46.1%) were the most encountered barriers for treatment.

Conclusion: Molar incisor hypomineralisation is a common condition that is encountered frequently by general dental practitioners as well as dental specialists, nevertheless most dentists were not aware about the prevalence of MIH in Jordan and indicated their need to improve their approach regarding MIH diagnosis and treatment.

Purpose: To analyze the functions of the stomatognathic system in children with or without molar-incisor hypomineralization (MIH).

Methods: For this cross-sectional study, 72 children aged 6-12 years were recruited and divided in two groups: with MIH (G1) and without MIH (G2). T-SCAN was used to verify the distribution of occlusal contacts, gnathodynamometer to measure maximum molar bite force, and Iowa Oral Pressure Instrument (IOPI) to assess the strength of facial expression muscles. The t test and paired t test (p ≤ 0.05) were used for statistical comparisons.

Results: The molars affected by MIH exhibited lower distribution of occlusal forces (p < 0.001) and lower maximum molar bite force (p < 0.05) compared to the molars in the control group. However, there was no difference between the MIH-affected sides compared to the unaffected side, nor between the molars affected by MIH and their antagonists (p > 0.05). There were no differences in the forces of the facial expression muscles between the groups.

Conclusions: These findings suggest that MIH significantly impacts occlusal force distribution and bite force, but not facial expression musculature.

Purpose: The purpose of the study was to assess and compare the masticatory performance in children receiving preformed metal crown by Hall technique and conventional technique.

Methods: Children having teeth indicated for restorative/endodontic therapy and belonging to the age group of six to ten years were invited to participate in the study. Eighteen children received preformed metal crowns (PMCs) by Hall technique. Meanwhile, nineteen children received preformed metal crowns by the conventional technique. Their masticatory performance (MP) was assessed at T0 (pre-intervention), T1 (day 1 post-intervention), T2 (1 week), T3 (2 weeks), T4 (1 month) and T5 (3 months) using Hue-check Gum® (University of Bern, Switzerland). The chewing gum samples were scanned within 24 h of their collection and processed in the ViewGum Software©. The software calculated the hue value (VOH) which indicated the masticatory performance of the individual. A questionnaire was given to the parents at T4 and T5 to assess any discomfort or pain associated with PMCs placed in both groups.

Results: The evaluation of masticatory performance using the two-color chewing method revealed reduction in MP on day 1 post-intervention (p < 0.001) for both groups. However, the MP values recorded at T5 were comparable to the baseline values at T0 (p = 0.009). No significant discomfort or pain was reported in both groups.

Conclusion: The findings of the current clinical study indicate that placement of PMCs by both conventional and Hall technique in children deteriorates their MP which equilibrates within 1 month.

Purpose: To determine the prevalence of malocclusion in Portuguese preschool children, to characterise occlusion in the deciduous dentition, and to study the relationship between malocclusion, sex, and age.

Methods: This cross-sectional study included 3-6 years old children, from 25 randomly selected kindergartens from the Lisbon district. Data were collected through an oral examination. Malocclusion was defined as the presence of any type of occlusion anomaly (anterior crossbite, edge-to-edge, increased overjet, open bite, deep overbite, posterior crossbite, scissor bite), spacing anomaly (crowding), or dentition anomaly (supernumerary teeth, agenesis, malformations). Canine class, terminal plane of the deciduous second molars and type of Baume arch were also recorded. Statistical analysis included descriptive and chi-squared test (α = 0.05).

Results: The sample included 426 children with a global prevalence of malocclusion of 60.6%. Occlusion anomalies were the most prevalent (59.2%), the most frequent being deep overbite (27%), increased overjet (22.1%) and posterior crossbite (14.1%). Crowding had a prevalence of 1.6% and agenesis of 1.4%. Class I canine (57.3%), straight second molar terminal plane (60.1%) and type I Baume arch (53.3%) were the most common. The mean overjet was 2.6 mm (sd = 2.1) and the mean overbite was 2.2 mm (sd = 2.1). Age was associated with the presence of occlusion anomalies (p = 0.03), and increased overjet prevalence was found to be higher in girls (p = 0.03).

Conclusions: The prevalence of malocclusion was high, with occlusion anomalies being the most prevalent. It is important to identify modifiable risk factors associated with malocclusion to prevent this condition in both the deciduous and permanent dentitions.

Purpose: To investigate the predictive ability of individual Caries Risk Assessments (CRA) regarding oral factors supplemented with social factors in relation to caries outcome in preschool children. Furthermore, to assess various models of CRA with oral and social factors included, aiming to identify the most suitable models for different age groups.

Methods: The design is a retrospective registry-based cohort study. Children visiting the dentists at ages 3 and 6 years were included. Data on oral and social factors were obtained from dental records, the Swedish Quality register for caries and periodontitis (SKaPa), and Statistics Sweden (SCB). Various models of CRA were designed, combining oral and social factors. Models were analyzed with univariable associations using simple logistic regression, and the results were presented as odds ratios (ORs). In addition, models were analyzed with area under the receiver operating characteristic (ROC) curve (AUC). Pairwise comparisons were conducted by DeLong's test, with p < 0.05 considered significant.

Result: Oral factors were the most significant for caries outcome (OR 9.6), followed by social factors: foreign background (OR 4.6), low income (OR 2.83), low education of the mother (OR 2.77), single-parent family (OR 2.11), and having ≥ 3 siblings (OR 1.71), (p < 0.01). The predictive ability of CRA improved when models combining oral and social factors were used, compaired to CRA based solely on oral factors (p < 0.05). An increase of up to 15% was seen when CRA was conducted closer to the outcome.

Conclusion: Models for Caries Risk Assessment including oral and social factors increase the predictive ability. Caries Risk Assessment has limited durability.

Purpose: Critically review and summarise existing knowledge on prevalence of oral, dental, and craniofacial side-effects of antineoplastic treatment in childhood cancer survivors (CCS).

Methods: A literature search was conducted for studies reporting on children aged 4-19 years treated for any type of malignancy up to the age of 15 years and for whom, at the time of the examination, more than 8 months have elapsed since the end of treatment. Data regarding dental late effects on teeth and craniofacial complex were collected and mean prevalence of each defect was reported.

Results: From the 800 articles identified, 17 studies fulfilled inclusion criteria and were included. A total of 983 CCS were examined, with the total number of healthy controls being 1266 children. Haematological malignancy was the most prevalent diagnosis with the age at diagnosis ranging between 0-15 years. Multiple antineoplastic protocols were implemented with the elapsed time being 8 months up to 17 years. One-third of CCS experienced at least one late effect, with corresponding value for the control group being below 25%. Among the defects identified clinically, microdontia, hypodontia and enamel developmental defects were recorded in 1/4 of CCS. Impaired root growth and agenesis were the two defects mostly recorded radiographically. The effect on dental maturity and on salivary glands was unclear.

Conclusion: CCS are at risk of developing dental late effects because of their disease and its treatment and therefore, routine periodic examinations are essential to record their development and provide comprehensive oral healthcare.
