Purpose: There have been limited reports on hearing impaired (HI) children's oral health, but no data on their dental fear. The aim of this study was to assess dental fear and caries prevalence in HI children and adolescents.

Methods: Upon ethical approval, all elementary and junior/senior high schools for the HI in Greece were invited to participate in the study. Students were asked to fill in the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). High school students additionally answered the Modified Dental Anxiety Scale (MDAS). Both questionnaires were translated into sign language by the same licensed interpreter. Caries prevalence was evaluated by dmfs/DMFS indices. Statistics by SPSS Statistics 28 (IBM) included parametric and non-parametric tests (significance at p ≤ 0.05).

Results: 33 elementary and 53 junior/senior high school students (mean age = 10.89 ± 2.63 and 16.23 ± 1.33 years, respectively) participated in the study. Means of CFSS-DS were 24.1 ± 9.9 and 26.9 ± 10.5, respectively. Mean MDAS (high school students) was 11.3 ± 4.7. Mean dmfs was 2.5 ± 5.2 for elementary and mean DMFS was 3.5 ± 5.4 for elementary and 7.3 ± 9.0 for high school students, higher than similar-age general population. Dental fear was not significantly associated to age, gender, severity of hearing impairment (HI) or caries prevalence.

Conclusion: HI children present similar dental fear values, but higher caries prevalence compared to similar-age Greek hearing population.

Purpose: To qualitatively analyse English-language Facebook comments pertaining to amber necklaces, aiming to explore user experiences, perceptions, and beliefs.

Methods: A sample of 1000 comments, totalling 2309 sentences, was collected via CrowdTangle. Sociodemographic details and the time elapsed since comment were also recorded. Using QDAMiner software, a single investigator manually performed deductive content analysis, categorising each sentence based on a predefined list from the "Seeking Health-Related Information Online" model. WordStat software was employed to assess word clouds and cluster analyses.

Results: The majority of comments originated from white users (88.5%), females (92%), and residents of the United Kingdom (35.8%). Key terms included "teething," "amber," "baby," and "love," with "teething" central in four identified clusters on the main map. Predominantly, sentences were categorised as "information is useful or potentially useful" (25.29%) and "positive experiences from using the amber necklace" (17.11%). Over time, there was an increase in comments categorised as "receiver's doubts related to information" and "acquisition or intention to acquire the necklace." Conversely, comments related to safety concerns, fear of accidents, dentist contraindication, and information quality decreased.

Conclusion: Facebook users actively engage with amber necklace content, frequently sharing positive experiences and recommending its use to other parents. Notably, concerns about associated risks appeared to diminish over time.

Purpose: Glass ionomer fissure sealant (GIS) and fluoride varnish (NaFV) are two preventive interventions applicable to pre-school children. However, their application effects on young children's behaviour are understudied. The study compared the effects of GIS and NaFV applications on dental anxiety (DA), cooperativeness and pain level in pre-school children when applied to primary second molars in outreach settings.

Methods: Four hundred and thirteen children were recruited for the study, out of which 228 were allocated to NaFV group whilstand 185 allocated to the GIS group. One calibrated examiner screened and randomly allocated the children into either group. Another calibrated examiner recorded the children's DA level and cooperativeness with Frankl Behaviour Rating Scale (FBRS) and Venham Behaviour Rating Scale (VBRS) throughout the treatment period. Subjects self-reported their pain levels using Wong-Baker Faces Scale (WBFS).

Results: Significant difference in postoperative anxiety was found using VBRS, with children in NaFV group having more positive scores post-treatment (p = 0.016). Only the type of preventive interventions significantly affected postoperative DA and patient cooperation (p = 0.032), whereas no other clinical findings and socio-demographic factors significantly influenced the children's behaviour postoperatively.

Conclusion: NaFV application is associated with less DA and more cooperative behaviour in pre-school children compared to GIS application although similar pain levels were recorded.

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.

Purpose: To evaluate and compare the effect of two enzymatic chemo-mechanical caries removal agents with conventional caries removal using rotatory instruments on the adhesion of composite resin to dentin of permanent teeth.

Methods: The sample comprised 30 permanent molars with caries lesions extending to the dentin, randomly distributed into three groups (n = 10 each): 1-Caries removal with rotary instruments (control group); 2-Caries removal with Papacárie Duo^® (F&A Laboratório Farmacêutico, São Paulo, Brazil); 3-Caries removal with Brix 3000™ (Brix S.R.L., Carcarañá, Argentina). After caries removal, the specimens were rinsed and dried. Scotchbond Universal™ adhesive (3 M, Saint Paul, Minnesota, USA) was actively applied in self-etch mode and light-cured. Resin composite increments were applied using a silicone mold (3 × 3 × 2 mm) and light-cured. Shear bond strength (MPa), work-to-debonding (J/m²), and shear modulus (kPa) were evaluated. For statistical analysis, the level of significance was set at 5%.

Results: The control group presented significantly higher shear bond strength values (8.50 ± 2.69 MPa) compared to the Brix 3000™ group (5.72 ± 1.55 MPa, p = 0.008). There were no significant differences between Papacárie Duo^® (6.66 ± 0.86 MPa) and the other groups (p > 0.05). Regarding work-to-debonding, the Papacárie Duo^® group had a significantly higher result (2944.41 ± 450.21 J/m²) than the Brix 3000™ group (1189.41 ± 504.13 J/m², p < 0.001) and the control group (967.10 ± 270.01 J/m², p < 0.001). Concerning shear modulus, the control group showed a significantly higher result (558.67 ± 168.96 kPa) than the Brix 3000™ group (339.79 ± 143.78 kPa, p = 0.008) and the Papacárie Duo^® group (223.04 ± 127.30 kPa, p < 0.001).

Conclusion: While the application of Papacárie Duo^® did not negatively affect composite resin adhesion to dentin of permanent teeth, the application of Brix 3000™ reduced adhesive forces, potentially limiting its clinical use. Further investigations are warranted to elucidate the effects of these materials on dentin substrate, particularly through clinical studies.

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: The aim of this study is to compare the effect of GSH (reduced glutathione) and KI (potassium iodide) on SDF (silver diamine fluoride) discolouration and dentine remineralisation.

Methods: Sixteen primary molars were utilised, yielding 4 dentine specimens each. Three specimens per tooth were allocated: one as a control and the others to experimental groups. Initial microhardness measurements were taken from one remaining dentine specimen per tooth. Subsequently, all groups underwent exposure to a demineralisation solution. Colorimetry assessed specimen colour, and post-second microhardness measurements on demineralised specimens, treatments were administered as follows: group 1 (control, n = 16): 38% SDF, group 2 (n = 16): 38% SDF followed by KI, group 3 (n = 16): 38% SDF with 5% GSH added by weight. Following pH cycling across all groups, colorimetry reassessed 48 dentine specimens. Final microhardness measurements ensued, followed by statistical analysis. Normality was checked via Shapiro-Wilk, and homogeneity via Levene's test. Independent samples t test compared normally distributed groups; Mann-Whitney U compared non-normally distributed groups. ANOVA compared means of normally distributed groups, and Kruskal-Wallis for non-normally distributed ones. Repeated measures ANOVA compared dependent groups with normal distribution, and Friedman test for non-normal. Post hoc Bonferroni analyses identified significant differences. IBM SPSS 25 was used to conduct analyses.

Results: The mean ΔE* values for SDF and SDF + GSH groups were significantly higher than those of the SDF + KI group (p < 0.05). Significant differences in L* values during final colour measurement were noted between the SDF + KI group and both SDF and SDF + GSH groups (p < 0.05). Although mean remineralisation microhardness measurements were higher than mean demineralisation microhardness measurements in all groups, statistical significance was observed only in the SDF and SDF + KI groups (p < 0.05).

Conclusion: The study found that the addition of 5% GSH by weight to SDF does not significantly affect discolouration. Moreover, the addition of 5% GSH to the SDF solution may have a minor impact on the remineralisation potential of SDF. The application of KI after SDF reduces discolouration and does not affect the expected remineralisation process.
