Assessing parental aesthetic acceptability of Silver Diamine Fluoride (SDF) staining is crucial for its potential implementation in paediatric dentistry in different regions. This study aimed to compare aesthetic perceptions and acceptance of SDF staining between Spanish and Italian parents, and assess weather acceptability is influenced by location, child's cooperation, or demographic background. A cross-sectional comparative study was conducted among Spanish and Italian parents at three university dental clinics, using a validated Italian version of the questionnaire "Parental perceptions of Silver Diamine Fluoride Dental Color Changes". 264 Spanish and 234 Italian parents participated in the survey. 41.8% of Spanish parents, compared to 65.4% of Italians, considered staining on posterior teeth acceptable (p < 0.001). 17.2% of Spaniards rated anterior teeth acceptable, versus 19.3% of Italians (p < 0.001). Italian parents showed increased acceptability as child's cooperation decreased. Acceptability levels in Spain remained more homogeneous, despite linear mixed model identifying a significant increase in acceptability scores from 'collaboration' to 'non-collaboration' scenario. Spanish and Italian parents found SDF staining on posterior teeth more acceptable than on anterior regions. Level of acceptance increased with child's uncooperative behavior. Spanish parents generally demonstrated a lower acceptance of SDF pigmentation compared to Italians.Trial registration: NCT, NCT06384326.

Background: Parental perceptions of staining due to silver diamine fluoride (SDF) could affect its utilization in paediatric dentistry. This study represents the second part of a wider project focused on SDF esthetic acceptability among Italian parents., Aim: To evaluate parental acceptance of SDF staining in Italy and to assess whether the parent's level of acceptance depends on location, child's behavior, or demographic background., Design: A cross-sectional study was conducted among Italian parents of children attending two university dental clinics. We used a validated Italian version of the questionnaire "Parental Perceptions of Silver Diamine Fluoride Dental Color Changes.", Results: Two hundred and thirty-four parents took part in the survey. Of parents, 65.4% considered the staining on posterior teeth esthetically "acceptable" or "somewhat acceptable," and 19.3% on anterior teeth (p = .001). In a scenario of positive cooperation, 48.5% of parents were "somewhat likely" or "very likely" to choose SDF to treat posterior teeth, and 17.6% on anterior teeth (p = .001). Level of acceptance increased as the difficulty the child would experience to receive conventional treatment increased., Conclusion: Staining on posterior teeth is more acceptable to parents than staining on anterior teeth. Level of acceptance on anterior teeth increases when sedation or general anesthesia is the alternative for the child., (© 2024 BSPD, IAPD and John Wiley & Sons Ltd.)

Objectives: To evaluate the influence of the gingival contour on the smile esthetics. The influence of size, symmetry, teeth involved in apically shifted gingival margins, and the distance and clinical training of the observer were investigated., Materials and Methods: Two groups were identified: 33 first-year dental students (inexperienced) and 40 last-year students (trained). Each observer expressed four evaluations on four different images assigning a score from 0 to 10. Using a picture of an "ideal" female smile, 10 variants were virtually created by shifting (2 and 4 mm) the gingival contour apically at different sites of the upper incisors and canines. A total of 292 evaluations were collected., Results: Considering a score >6 for a "pleasant smile," only one 4 mm single alteration at the canine gingival contour obtained an insufficient score. "Observational distance" and "clinical training" did not influence the final score, while size and symmetry of alterations displayed a significant role., Conclusions: The dental training of the observer and a close interpersonal distance seemed to be irrelevant in the esthetic perception of gingival margin alterations., (© 2022 The Authors.

Aim: During the COVID-19 pandemic, restrictive rules were imposed around the world to limit the spread of the virus. The present study aims to investigate how the pandemic and the consequent restrictions have affected the lives and oral health of Italian families with children aged 0-14 years., Materials: Through a questionnaire distributed online from December 2020 to March 2021 the following aspects were investigated: family income during the pandemic, fear of the pandemic, dietary habits, perceived risk of infection in a dental practice and perceived children oral health status during the pandemic., Conclusion: The pandemic has not drastically changed the socio-economic conditions, the dietary habits and the oral health condition of most Italian children. Nevertheless, the pandemic seems to have highlighted significant macro-regional differences regarding the satisfaction with the response of the regional health services to the pandemic. The continuation of the pandemic and the possible socio-economic effects could favour new changes in lifestyles, oral health and discrepancies regarding health care access, which deserve to be the subject of further investigation.

The aim of the study was to test an information booklet containing suggestions to parents on how to prepare their child for the first dental visit. Forty-five children and one parent per included child took part in the trial. Children were randomized in two groups; the information booklet was e-mailed to the parents of the study group. At the end of the visit, the dentist and the parent evaluated the child's behavior through the Frankl Behavior Rating Scale (FBRS) and the utility of the booklet through a Likert scale. The children evaluated the pleasantness of the visit and the perceived pain through the Wong-Baker FACES ® Pain Rating Scale (WBFPRS). Parents evaluated the information booklet as highly understandable and useful. According to the dentist, informed children were more cooperative (FBRS median score: 4; IQR: 3.5-4) than the control group (median score 3; IQR: 2-4) ( p = 0.013; Mann-Whitney U test). Children prepared with the booklet reported less pain (WBFPRS: 0.40 ± 0.82 vs. 1.42 ± 1.99; p = 0.034; t -test;) and tended to evaluate the visit as more enjoyable (WBFPRS: 1.1 ± 2.14 vs. 2.75 ± 3.43; p = 0.064; t -test) than unprepared children. The information booklet increases the child's ability to cooperate during the visit and could represent a useful instrument for the clinical practice.

Aim: The aetiology of Molar Incisor Hypomineralisation (MIH) is currently unclear. Over time, several aetiological hypotheses have come forward, including pre- and perinatal medical problems and postnatal illness. The aim of this case-control study is the identification of possible predisposing factors involved in MIH aetiology., Methods: Methods Study Design: By hypothesising the probability of at least one predisposing factor present 2.5 times more in MIH cases than in controls, with an estimated prevalence of MIH patients requiring therapy equal to 30%, at a unilateral alpha level of 5% and a power of 80%, 63 couples of subjects are needed with an allocation ratio of 1:1; individual matching for age and gender was carried out. After clinical examination, 78 children with MIH (EAPD criteria) were recruited (mean age 9.36 years). An anamnestic form filled-in by a parent was used to collect data on possible predisposing factors including demographic characteristics, pregnancy, birth, childhood medical illness and medications' intake., Statistics: One-tail McNemar chi square test was used to evaluate the significance of the association between predisposing factor and MIH; odds ratio and 95% confidence intervals were computed., Conclusion: A multifactorial aetiology may be advocated for MIH development; in particular, further investigations are required to confirm and clarify the role of genetic factors.

Background: The original English version of the questionnaire 'Parental Perceptions of SDF Dental Color Changes' was used among parents in the New York City metropolitan area., Aim: To develop an Italian version of the questionnaire and to assess its validity., Design: The construct validity and the internal consistency were assessed in a convenience sample of Italian parents of 251 young healthy children seen at the University of Bologna and Pisa. Forward-backward technique was carried out for the translation of the questionnaire. Kaiser-Meyer-Olkin measure of sampling adequacy was equal to 0.91, and Bartlett's test of sphericity was statistically significant (P = .001), so the items were treated with the exploratory principal component analysis (PCA)., Results: Cronbach's alpha ranged from 0.69 to 0.95. PCA demonstrates that all the items load on the first component (87% of explained variance). All the Spearman correlation coefficients between each subscale (positive scenario: 0.563; negative scenario: 0.665) and the general acceptability showed significant correlation (P = .0001). Different age, educational level, and family income of the parents did not produce statistically significant different scores on any of the subscales (P > .05; Mann-Whitney test)., Conclusion: The Italian version of the questionnaire showed high internal consistency and construct validity and was appropriate to be used in an Italian population., (© 2021 BSPD, IAPD and John Wiley & Sons Ltd.)

Aim: Autism Spectrum Disorder (ASD) is characterised by communication deficits and repetitive unusual behaviours. The behaviour guidance of these children represents a challenge for the dental team. The aim of the study was to evaluate the oral health status in a group of Italian children with ASD., Materials and Methods: Study Design: Sixty-four Italian children with ASD and 64 controls were included. Data were collected by means of questionnaires and clinical examinations., Results: Dental trauma (p=0.007), bruxism (p=0.001) and biting objects habit (p=0.021) were more frequent in the study group; fluoride exposure was lower (p=0.001) (chi-square test). The mean plaque index was 1.48 ±0.75 in the study group and 0.81±0.56 in the control group (p=0.001; Mann-Whitney U test); the mean dmft/DMFT was 3.00 ±1.2 and 2.3 ±1.8 in the study group and 1.8 ±1.1 and 1.0 ±1.1 in the control group (p<0.001; Mann-Whitney U test). Anterior open bite was more frequent in the study group (p=0.013; Chi-square test). No significant differences were found for enamel defects, molar relationship, posterior crossbite and deep bite. Significantly more children with ASD showed a negative behaviour (80% vs 35%: p =0.001; Chi-square test). CONCLUSION Children with ASD have a poorer oral health status than healthy children. The early establishment of a home dental hygiene should be encouraged.

Background: Oral breathing and downward tongue position are generally associated with transverse hypo-development of the upper maxilla. Rapid maxillary expansion aims to expand the upper maxilla transversely. This pilot retrospective clinical study evaluates the effects of rapid maxillary expansion therapy on the resting position of the tongue, on the position of the hyoid bone and on clinical respiratory pattern in a group of mouth breathing patients with mono- or bilateral cross-bites due to transversal deficits of the maxilla., Methods: A total of 39 prepubertal oral breathing subjects with posterior cross-bite (mean age 8.5 year) have been studied. Before (T0) and after treatment (T1), changes in the position of the hyoid bone and tongue were evaluated by comparing latero-lateral radiographs (TLL), while the modification of respiratory patterns by a clinical and anamnestic assessment., Results: After the treatment, the dorsum of tongue moved closer to the palatine vault, the position of the hyoid bone did not undergo significant variations and the respiratory pattern clinically improved in 64% of subjects., Conclusions: In patients in early stages of oral respiratory development, rapid maxillary expansion promoted correct tongue position but did not produce significant changes in the position of the hyoid bone. It has been observed a general improvement of the breathing pattern.

Craniofacial features of 18 individuals with Turner Syndrome (TS) were compared with age and gender matched healthy individuals. Dental history, panoramic radiograph, dental casts and cephalometric measurements were assessed. The dental casts analysis showed a significantly higher PH/PW ratio in individuals with TS under GH therapy compared to healthy individuals (p=0.004; paired t-test). This data objectively supported the definition of a high-narrow palate. The ANB angle and the Wits index were similar in the two group, showing a skeletal class I malocclusion. The vertical characteristics did not differ between the two groups, showing a mesofacial growth pattern. Our results showed similar cephalometric characteristics in individuals with TS treated with GH and healthy controls., (Copyright 2020 Biolife Sas. www.biolifesas.org.)

Craniofacial features of 12 children with Noonan syndrome (NS) were compared with age and gender matched healthy children. Dental history, panoramic radiograph, dental casts, and cephalometric measurements were assessed. The palatal height was significantly increased in the study group compared with the control group (p = .009; paired t-test). The palatal width was significantly reduced in the study group compared with the control group (p = .006; paired t-test). The mean SNB was reduced in the study group compared with the control group (p = .02; paired t-test) and the ANB increased (p = .009; paired t-test). The mean Sum (NSAr + SArGo + ArgoMe) angle and SN-GoMe were increased in the study group compared with the control group (respectively, p = .015 and p = .002; paired t-test). The cephalometric analysis assessed a retruded position of the mandible, skeletal class II characteristics, and a vertical growth pattern. The mandibular hyperdivergency was associated to a positive overbite., (© 2021 Wiley Periodicals LLC.)

Age estimation is widely applied in several clinical and forensic fields. The radiographic evaluation of dental development is one of the most accepted tools for this purpose. Among the different methods proposed, Demirjian's method was the most extensively used and tested in the medical literature revealing that the original standards for the French-Canadian population tends to over-estimate the age of different population groups. The aims of this study were to evaluate the applicability of the Demirjian method in a sample of Italian children with Down syndrome (DS) and to compare the data with age and gender matched healthy subjects (non-DS). A retrospective study was performed on 146 orthopantomograms of DS individuals aged 6.3-16 years. The mean chronological age (CA) and the mean dental age (DA) were calculated. Using Cohen's kappa statistics, the inter- and intra-examiner agreement was reported as good (k = 0.75) and very good (k = 0.86). The differences between CAs and DAs were statistically significant for males and females (Wilcoxon Signed Rank test; p < 0.05). The median overestimation was 0.6 years in males and 0.9 years in females. Demirjian's method is unsuitable for dental age estimation in DS individuals. The same trend in overestimation was found in the control group. Comparing DS and non-DS subjects, the differences between DAs were not statistically significant for both males and females revealing that the dental development process is similar., (Copyright © 2019 Elsevier B.V.

Objectives: To demonstrate the efficacy of laser photobiomodulation (PBM) compared to that of placebo on severe oral mucositis (OM) in pediatric oncology patients. The primary objective was the reduction of OM grade (World Health Organization [WHO] scale) 7 days after starting PBM. Secondary objectives were reduction of pain, analgesic consumption, and incidence of side effects., Methods: One hundred and one children with WHO grade > 2 chemotherapy-induced OM were enrolled in eight Italian hospitals. Patients were randomized to either PBM or sham treatment for four consecutive days (days +1 to +4). On days +4, +7, and +11, OM grade, pain (following a 0-10 numeric pain rating scale, NRS) and need for analgesics were evaluated by an operator blinded to treatment., Results: Fifty-one patients were allocated to the PBM group, and 50 were allocated to the sham group. In total, 93.7% of PBM patients and 72% of sham patients had OM grade < 3 WHO on day +7 (P = 0.01). A significant reduction of pain was registered on day +7 in the PBM versus sham group (NRS 1 [0-3] vs. 2.5 [1-5], P < 0.006). Reduced use of analgesics was reported in the PBM group, although it was not statistically significant. No significant adverse events attributable to treatment were recorded., Conclusions: PBM is a safe, feasible, and effective treatment for children affected by chemotherapy-induced OM, as it accelerates mucosal recovery and reduces pain., (© 2018 Wiley Periodicals, Inc.)

Aim: To evaluate the oral health status in Alzheimer's disease (AD) patients., Materials and Methods: A descriptive study was performed on 120 AD patients (60 institutionalized in a public institute and 60 attended a daytime center), from September 2013 to January 2014. About 103 subjects formed the control group. The following medical and dental data were collected: dementia severity, pharmacological therapy, physical status (American Society of Anesthesiologists [ASA]), decayed (D), filled (F), and remaining natural teeth (T), DF/T ratio, community periodontal index (CPI), and gingival index (GI). A t-test for independent samples and the Spearman's correlation test were used to evaluate all variables. The significance level was set at 0.05., Results: Statistically more AD patients (91.7%) were under pharmacological therapy and their physical status was more severe (ASA 2, ASA 3) compared with control subjects (p < 0.001). Moreover, they presented numbers of D, CPI, and GI significantly higher (p ≤ 0.005). In the institutionalized subgroup, statistically more moderate and severe AD cases were detected and more patients were edentulous (p < 0.001). Noninstitutionalized patients presented DF/T ratio, CPI, and GI significantly lower (p ≤ 0.024). A significant weak negative correlation (r = -0.121 to -0.372) between epidemiologic indices and AD severity was observed., Conclusion: Alzheimer's disease patients show a low oral health status that decreases progressively as the disease severity aggravates. Therefore, further studies are necessary to investigate oral health care interventions for AD patients., Clinical Significance: It would be beneficial to introduce trained professional figures in specialized elderly institutions for regular follow-up visits and professional oral hygiene procedures. This task has to be coordinated with the treating physician, family members, and/or caregivers. Knowing that the severity of AD has a negative effect on the oral health status and the type of institutionalization exacerbates it.

Background: Audiovisual distraction using video eyeglasses is useful in managing distress and reducing fear and anxiety in healthy children during dental treatments., Aim: To evaluate the effect of audiovisual distraction on behavior and self-reported pain of children with special healthcare needs (SHCN) without intellectual disability during dental restorations and its influence on the operator stress and the time of the appointment., Material and Methods: This randomized controlled crossover trial comprised 48 children with SHCN requiring at least two dental restorations. One restoration was done wearing the video eyeglasses and one wearing conventional behavior management techniques. Subjective and objective pain was evaluated using the Faces Pain Scale - Revised (FPS-R) and the revised Face, Leg, Activity, Cry, and Consolability scale (r-FLACC). The operator stress using a VAS, the time of the appointment, and the child satisfaction were recorded., Results: The use of video eyeglasses significantly reduced the operator stress. The bivariate analysis showed that the mean FPS-R score and the mean r-FLACC score were significantly lower using the video eyeglasses only during the second clinical session., Conclusion: Audiovisual distraction could be useful in managing distress in SHCN children without intellectual disability but cannot replace the conventional behavior management techniques., (© 2017 BSPD, IAPD and John Wiley & Sons A/S.

Aim: Dental trauma is a frequent finding in people with special health care needs. The aim of this study was to determine the prevalence of dental trauma in a sample of Italian children and adolescents with special health care needs., Materials and Methods: 556 medical and dental records of children and adolescents visited from January 2010 to March 2015 were examined. Information about medical diagnosis, gender, site and type of dental trauma (DT) were collected. According to age and reflecting the dentition stage, the sample was divided into 3 groups: subjects aged 0-5 years (group A, primary dentition), 6-11 years (group B, mixed dentition), 12-18 years (group C, permanent dentition)., Results: 113 individuals experienced a DT (prevalence 20.3%), with no difference in relation to gender. Individuals with cerebral palsy and autism showed the highest frequency of DT: 39.6% and 30.4%, respectively. The highest frequency of DT occurred both in group A (21.8%) and B (21.5%), which differed significantly from group C (9%). Avulsion was the most frequent type of DT in the primary dentition (24%) and enamel-dentin fracture without pulp exposure in the permanent dentition (60%). Upper central incisors were the most affected teeth., Conclusion: The prevalence of DT in a sample of Italian children and adolescents with special health care needs is high, especially in young individuals with cerebral palsy and autism. Preventive strategies for those patients should be developed in order to reduce the risk of DT.

Pallister-Killian syndrome (PKS) is a rare sporadic multi-systemic developmental disorder caused by a mosaic tetrasomy of the short arm of chromosome 12. A wide range of clinical characteristics including intellectual disability, seizures, and congenital malformations has previously been described. Individuals with PKS show a characteristic facial phenotype with frontal bossing, alopecia, sparse eyebrows, depressed nasal bridge, long philtrum, telecanthus, and posteriorly rotated ears. Oro-dental features, such as "Pallister lip," macroglossia, delayed eruption of primary teeth, high arched-palate, prognathism, and cleft palate have been occasionally reported in the medical literature. The aim of the study was to assess the oro-dental phenotype of PKS and to describe the oral health status in a cohort participating in the First European Workshop on PKS. A clinical dental examination was performed in 21 Caucasian probands and data regarding medical and dental history collected. Twelve probands (57%) showed an atypical dental pattern, with multiple missing teeth (primarily the first permanent molars) and 2 (10%) a double teeth. The severity of gingivitis and dental caries increased with age and gingival overgrowth was a common finding. A characteristic occlusive phenotype was found: a high-arched palate with mandibular prognathism associated with an anterior openbite and crossbite and with posterior crossbite (unilateral or bilateral). The prevalence of oral habits (non-nutritive sucking, mouth breathing, bruxism) was high, even in older probands. This study suggests that individuals affected by PKS should be observed closely for oro-dental diseases and a multidisciplinary approach is needed to implement the right preventive measures. © 2016 Wiley Periodicals, Inc., (© 2016 Wiley Periodicals, Inc.)

Aim: To investigate with a reliable method the oral features in Italian patients in remission from cancer, highlighting the relationship with age at cancer therapy and to compare the data with healthy controls., Materials and Methods: Twenty five childhood cancer survivors treated under the age of 10 years with chemotherapy w/wo Haemopoietic Stem Cell Transplantation and/or head-neck Radiotherapy, in remission from cancer for at least 3 years, were examined for dental caries and enamel defects. To assess dental age and dental abnormalities a panoramic radiograph was taken. Patients were grouped according to age at cancer therapy (<3 years: subgroup Y; 3.1-5 years: subgroup M; >5 years: subgroup O). A control group of 26 healthy children was included., Results: There was not a statistically significant difference in caries prevalence between the two groups. A statistically significant difference between the two groups was found for enamel defects, dental abnormalities and dental age. The chi-squared test revealed a relationship between age at therapy and specific dental abnormalities., Conclusion: This study shows that cancer therapy may increase the risk of development of enamel defects and dental abnormalities, especially in children treated under the age of 3 years.
