Prevalence of sealant in an Italian paediatric population: an epidemiological study.

AIM: The use of sealants is an effective measure for the prevention of pit and fissure caries in children and it has been well documented by several studies In order to plan and establish a preventive national programme, it is important to know the epidemiological pattern in an Italian paediatric population, correlated to the risk of caries, DMFT and other sociodemographic factors. METHODS: This study was conducted on 2,442 children aged between 6 and 12 years attending the paediatric dentistry department of the University of L'Aquila, Italy. In addition to the oral examination, a questionnaire was administered on bad habits and the family perception of sealing. For descriptive analysis, the sample was stratified into two groups based on the presence/absence of at least one tooth with sealant. The differences between discrete and nominal variables, reported as absolute and percentage frequencies, were assessed by applying the χ2 test or the Fisher's exact test, as appropriate. Continuous variables were expressed in terms of mean values and their standard deviation(±DS) and the differences between the two groups under consideration were analysed through Student's t-test. The tests used are two-way and a significance level of 5% was applied. The statistical analysis was carried out using the statistical package STATA/IC 15.0 (StataCorp LLC, Texas, USA). CONCLUSION: The application of sealants to healthy occlusal surfaces is the best aid in preventing the development of caries in these areas, and this is especially important in childhood and adolescence, when the incidence of this pathology is particularly high.

Instrumental Timed Up and Go test discloses abnormalities in patients with Cervical Dystonia.

Background Cervical dystonia is a movement disorder characterized by involuntary and sustained contraction of the neck muscles that determines abnormal posture. The aim of this study was to investigate whether dystonic posture in patients with cervical dystonia affects walking and causes postural changes. Methods Patients with cervical dystonia and a group of age-matched healthy controls underwent an instrumental evaluation of the Timed Up and Go Test. Findings All the spatio-temporal parameters of the sub-phases of the Timed up and go test had a significantly higher duration in cervical dystonia patients compared to the control group while no differences in flection and extension angular amplitudes were observed. Indeed, we found that Cervical Dystonia patients had abnormalities in turning, as well as in standing-up and sitting-down from a chair during the Timed up and go test than healthy controls. Interpretation Impairment in postural control in cervical dystonia patients during walking and postural changes prompts to develop rehabilitation strategies to improve postural stability and reduce the risk of fall in these patients.

Prevalence of Early Childhood Caries (ECC) in a paediatric italian population: An epidemiological study.

AIM: The present work aims to evaluate, through an epidemiological study, the prevalence of Early Childhood Caries in an Italian paediatric population, aged up to 71 months, evaluating some determinants that will be illustrated in this study in order to adopt preventive care and intervene as early as possible to limit the development of this disease. METHODS: The sample consisted of 76 children aged up to 71 months who were examined at the PAediatric Dentistry Clinic of the University of l'Aquila. Parents were informed of the research that was taking place. All read the information sheet explaining the study and signed the informed consent where it was emphasised that the data collected would be treated and stored in a strictly confidential manner, pursuant to the Legislative Decree 196/2003 in force in Italy since June 30, 2003, regarding the protection of individuals with regard to the processing of personal data. At the end of this study, a standardised questionnaire administered. The questionnaire, divided into two parts, made it possible to acquire information regarding the characteristics of the population. First part: General data of the child and the medical history of the mother and father; Second part: The age and gender of the child, the type and duration of breastfeeding, the use of sugary pacifiers, oral hygiene and frequency of consumption of sugars drinks and food, identifying the starting age. RESULTS: Evaluating the dmft of each child, 40.79% of our sample population is affected by ECC; 57.89% of the children used the pacifier and 13,16% of them have or have used it with honey with a p value of 0.001, therefore this parameter was statistically significant, together with the intake of candies, chocolates and sugar drinks. The data was collected for a period of about 12 months, consequently a descriptive statistical analysis was conducted in which the characteristics of the population under consideration were outlined. Discrete and nominal variables have been described with frequencies and percentages. The percentage differences were evaluated using the chi-square test and the Fisher test. Quantitative variables were expressed in terms of mean and standard deviation and significance was assessed by the Mann-Whitney test. The level of significance was established as p <0.05. A Logistic Regression was conducted to evaluate the risk factors associated with a dmft>0 setting, dmft=0/dmft>0 as the dependent variable and the variables investigated as explanatory variables. The evaluation of the association was reported as the Odds Ratio with the 95% confidence interval. The statistical analysis was carried out using the Stata 12/1C statistical package. CONCLUSION: ECC is a multifactorial disease in which eating habits play a very important role. A diet that from childhood is characterised by a high consumption of sugar-rich food and drinks is highly associated with the incidence of ECC in later years.

Clinical effectiveness of inhalation conscious sedation with nitrous oxide and oxygen for dental treatment in uncooperative paediatric patients during COVID-19 outbreak.

AIM: The aim of this study was to evaluate the features of inhalation conscious sedation for urgent dental treatments in uncooperative paediatric patients during COVID-19 outbreak. MATERIALS AND METHODS: Forty-two uncooperative patients, attending primary and secondary schools, were submitted to emergency dental treatments with inhalation conscious sedation using nitrous oxide and oxygen during COVID-19 pandemic. Collected data included: number of working sessions, success/failure, adverse events, side effects, number of teeth treated; type of dental procedure. Parents filled in an e-mailed questionnaire on post-discharge children status to evaluate: pain; crying; fever; vomiting; headache; drowsiness; excitability; irritability; ability to eat; need for drugs. RESULTS: One working session was carried out in 29 patients, 2 working sessions were carried out in 6 patients and 3 working sessions were carried out in 7 patients. Success rate was 87.1%. In relation to success, there was no statistically significant difference between males and females, healthy and disabled patients, respectively; while there was a statistically significant difference between patients attending primary and secondary schools (p=0.023). No adverse events occurred. The most frequent side effect was nausea. In relation to side effects, there was no statistically significant difference between males and females, healthy and disabled patients, patients attending primary and secondary schools, respectively. In relation to e-mailed questionnaires on post-discharge children status, 29.6% of the patients had pain, 22.2% vomited, 14.8% had headache, 18.5% experienced drowsiness, 29.6% failed to eating normally, 35.2% needed to take drugs. None of the patients cried, had a fever, exhibited irritability and excitability. CONCLUSION: Inhalation conscious sedation is a safe, practical and effective procedure with minimal side effects to perform emergency dental treatments in uncooperative paediatric patients during COVID-19 outbreak.

Oral health conditions in Wilson's disease patients: A clinical diagnostic study.

AIM: The aims of this study were: To evaluate oral health conditions, oral health behaviours and eating habits in Wilson's disease (WD) patients; to assess the possible relationship between oral health status and long-term pharmacological therapies undertaken. METHODS: Sixty WD patients were selected and their data were compared to those of an age-matched control group of 62 subjects. Clinical examinations were carried out and a questionnaire on oral health behaviours and eating habits was submitted to both groups. WD patients were interviewed on long-term pharmacological therapies undertaken. Statistical analysis was performed. RESULTS: The mean DMFT value was 3.75±4.65 in the WD group and 2.81±4.65 in the control group. The difference in the mean DMFT value between the two groups was not statistically significant. Modified Dental Enamel Defects (DDE) Index showed significantly higher values in WD group than in control group. No statistical differences in Visible Plaque Index (VPI), Gingival Bleeding Index (GBI) and malocclusions were observed between groups. In relation to the questionnaire, the differences between groups were statistically significant for: dental visits in a year; brushing teeth after a snack; drinking soft beverages; using mouthwash. For WD patients no statistical correlation between oral health status and long-term pharmacological therapies undertaken was observed. CONCLUSION: WD patients did not show worse oral health conditions than the control group, despite worse oral health behaviours and eating habits. Nerveless, WD patients showed higher presence of dental enamel defects. Finally, for WD group oral health status was not correlated to the long-term pharmacological therapies.

Autism spectrum disorders and oral health status: review of the literature.

AIM: Autism Spectrum Disorder (ASD) is characterised by impairments in communication and social relationships and by a narrow, repetitive and stereotyped repertoire of activities, behaviours and interests. The aim of this work is to evaluate how these characteristics have an impact on oral health. MATERIALS AND METHODS: A search was conducted through MEDLINE/PubMed and Web of Science in order to evaluate the oral health status of children with ASD and the correlation between ASD and dental caries, periodontal disease, dental injuries, oral microbiota, as well as the different strategies, approach and treatments in ASD patients. Forty-six articles were selected. RESULTS: Children with ASD are at higher risk of caries, alteration of the periodontal status, alterations of the oral microbiota and increased risk of traumatic injuries. CONCLUSION: Since ASD is a haeterogeneous disease with a wide range of expressions in individuals, adapted and specific strategies are needed. ASD children represent a challenge for the dental community.

OSAS in developing age: Screening of a Southern Italy population.

AIM: The aim of this study was to determine the prevalence of OSAS' risk in children of the province of Catanzaro, Italy. MATERIALS AND METHODS: A sample of 2445 scoolchildren aged 6 to 12 years of the province of Catanzaro (Italy) were administered the Pediatric Sleep Questionnaires (PSQs) in its validated Italian version. A total of 1772 questionnaires were collected; however, 130 of them were excluded, and 1642 questionnaires were accepted and scored. RESULTS: According to final scores of questionnaires, 172 children (10.47%) were considered at risk for OSAS. No statistically significant association between sex and risk of OSAS was found (p = 0.189). The risk of OSAS was equally distributed in all ages (p = 0.984). It was found that the most common habits in children with risk of OSAS were: snoring, heavy or noisy breathing, oral breathing, xerostomia, difficulty waking up in the morning, behavioural disturbances during the day and excess weight. CONCLUSION: The study showed a high risk of OSAS, suggesting the importance of first-level screening and the need to pay special attention to the diagnosis of this syndrome.

Assessing changes in oral health-related quality of life and body growth in 3-5 years old children following dental treatment under general anaesthesia due to severe dental caries.

AIM: To evaluate the impact of oral treatment under general anaesthesia (GA) on oral health-related quality of life (OHRQoL) in children with severe dental caries; to assess the effect of dental treatment under general anaesthesia on children's weight (Wt), height (Ht) and Body Mass Index (BMI). METHODS: One hundred uncooperative 3-5 years old children were selected. OHRQoL, assessed with the Early Childhood Oral Health Impact Scale (ECOHIS), Ht, Wt and BMI were measured at baseline and after 1 year from dental treatment under general anaesthesia. STATISTICS: All statistical procedures were performed using the Statistical Package for the Social Sciences (SPSS for Windows). ANOVA analysis was made to assess the effect of GA procedures on oral health quality of life in uncooperative children. RESULTS: After 1 year, the reductions for the ECHOIS components were statistically significant (P < 0.0001). Children showed a significant improvement in relation to pain, eating, sleeping and behavioural problems. At follow-up, there was a significant improvement in the anthropometric measures: 55% of children increased the percentile curves for weight and BMI; 44% for height. CONCLUSIONS: One year after a complete treatment under GA, both the OHRQoL and the growth improved.

Oral health status and Unmet Restorative Treatment Needs (UTN) in disadvantaged migrant and not migrant children in Italy.

AIM: Despite a global decline in caries experience in children, dental caries remains a common and persistent public health problem, being more prevalent among socioeconomically disadvantaged groups. The aim of this survey is to evaluate DMFT index, caries prevalence and Unmet Restorative Treatment Needs (UNT) index in migrant and not migrant children with low income, in Campania region (Italy), in order to plan and build up strategies for promoting dental health in children and adequate health care for vulnerable groups. MATERIALS AND METHODS: A sample of 553 children (age range: 12-14 years old) were recruited from volunteer patients at a charitable foundation in Naples (Italy) and were categorised into 2 subgroups, according to their status of "migrant" or "not migrant". Parents completed a questionnaire in order to investigate demographic and oral health behaviour. The participants were healthy and from low family income levels. DMFT scores and caries prevalence were calculated; UNT index was also calculated [D?(D + F)]%. The mean DMFT values related to the examined variables were calculated using one-way ANOVA. RESULTS: Mean DMFT and UTN index were 3.92±2.92 and 86.3% for migrants, and 3.29±3.21 and 68.4% for not migrants, respectively. The difference in the mean DMFT between the two groups was statistically significant (p=.027). Caries prevalence was 77.5% and 55.9% in the migrant group and in the not migrant group, respectively. High DMFT values were statistically associated to history of previous dental visit, sugar intake, brushing teeth once a day, and low mothers' educational level for both groups. CONCLUSION: Economically disadvantaged children showed high levels of dental caries. Furthermore, DMFT values, caries prevalence and unmet restorative treatment needs index among migrant children were higher than that of not migrant. In order to reduce inequalities in dental caries experience, there is a need to design policies aimed at primary prevention through health promotion programmes.

Disease progression in blepharospasm: a 5-year longitudinal study.

BACKGROUND AND PURPOSE: The clinical manifestation of dystonic spasms in blepharospasm (BSP) patients may be heterogeneous. Whether the varying phenomenology of eyelid spasms becomes manifest sequentially during the course of the disease or aggregates in separate clusters according to different disease courses is still unclear. For this purpose, the clinical features in BSP patients were evaluated longitudinally over a 5-year period and also the blink reflex recovery cycle was tested in a subgroup of BSP patients. METHODS: Sixty BSP patients were videotaped at time 0 and after approximately 5 years of follow-up. Two experts in movement disorders, who were blinded to the video order, reviewed the videotapes and scored the severity of BSP using the Blepharospasm Severity Rating Scale. Changes in the R2 recovery index were also evaluated in 18 patients twice, i.e. upon enrolment and at the follow-up. RESULTS: The severity of BSP worsened significantly over the 5-year follow-up period owing to the appearance or the increased duration and frequency of prolonged spasms. It was also found that the blink reflex recovery cycle worsened at follow-up in comparison with the baseline. CONCLUSIONS: This study shows that the disease progression of BSP is characterized by the appearance or worsening of prolonged spasms. Prolonged spasms are accompanied by changes in the excitability of brainstem interneurons. Aging-related effects may exacerbate the pathophysiological mechanisms underlying spasms.

Paediatric oral surgery: endoscopic approach in ameloblastic fibroma management. A preliminary report.

AIM: Ameloblastic fibroma (AF) is a rare benign odontogenic tumor of slow-growing behaviour characterised by proliferation of both epithelial and mesenchymal odontogenic tissues. Treatment of AF is usually conservative by means of enucleation, curettage and long term follow-up. CASE REPORT: This report describes a case of AF in a 12-year-old boy. Examination of the oral cavity revealed absence of tooth 3.7 and mild swelling in the same mandibular area. Orthopantomography and Cone Beam Computed Tomography (CBCT) showed a wide multilocular radiolucent lesion at the left mandibular angle, extending from the first molar to the lower part of the mandibular branch; agenesis of tooth 3.7 and displacement of tooth 3.8. Surgical excision was performed under general anaesthesia. A fiberscope was used to perform a more conservative bone removal and extraction of tooth 3.8. Furthermore, an accurate curettage of the bone site was performed. The histological investigation showed an AF pattern: an epithelial cell component arranged in nests and tubules immersed in a stroma of low differentiated mesenchymal tissue. No sign of recurrence has been observed during the 6-month follow-up period. CONCLUSION: Although AF is a rare tumor, it is more prevalent in children's jaw. A new intra-operative visual technique could provide a conservative treatment by minimising bone deformities and permitting an accurate bone curettage.

Dental Sealants Part 4: Bisphenol A: What dentists should know.

BACKGROUND: Bisphenol A (BPA) is a synthetic chemical resin used worldwide to produce plastic products. It is also a component of the bisphenol A diglycidylether methacrylate (Bis-GMA), which is a monomer found in dental resin-based materials (including resin-based dental sealants, RBSs). The controversy about its possible toxicity begins around the early '30s. Even if the amount of BPA released by dental sealants is well below the limit proposed by the U.S. Environmental Protection Agency and the European Food Safety Authority, we can reduce the risk of exposure, particularly for children, following precautionary measures.

Is there an association between various aspects of oral health in Southern Italy children? An epidemiological study assessing dental decays, periodontal status, malocclusions and temporomandibular joint function.

AIM: To describe the current oral health status of primary school children in Southern Italy, to investigate if there is an association between malocclusions and temporomandibular disorders (TMDs), and to investigate if there is an association between dental caries and periodontal disease. MATERIALS AND METHODS: Study design: Transversal epidemiological study. We examined 1086 children, considering them of the same socioeconomic status (medium). The Decayed, Missing, Filled (DMF) index and the Community Periodontal Index (CPI) were used to assess decay and periodontal status. Moreover, orthodontic and gnathologic evaluations were performed. RESULTS: Children had a mean age of 10.3±0.72 yrs, 41.6% had active dental caries in permanent teeth and 54.8% experienced periodontal problems. The 54.3% of patients had Angle Class I, 40.1% Class II and 5.5% Class III. The 13.8% of children had a deviated opening pattern of the mandible, and 2.2% of them had TMJ pain. DMF indices greater than 0 were associated with positive CPI. Males were more susceptible to periodontal disease, compared to females. TMJ pain was found associated with a decreased overbite. STATISTICS: Descriptive statistics for continuous data, and frequencies and percentages for categorical and ordinal data were calculated. Univariate linear and logistic regression model, with ? calculations, was used to assess associations between dental caries status and CPI, and between malocclusions and gnathologic aspects. CONCLUSIONS: This study found a noticeable prevalence of oral diseases among children of Southern Italy and an association between malocclusions and TMDs, periodontal disease and dental decay. Thus, a higher number of preventive interventions are recommended in the area.

Spread of dystonia in patients with idiopathic adult-onset laryngeal dystonia.

BACKGROUND AND PURPOSE: Adult-onset laryngeal dystonia (LD) can be isolated or can be associated with dystonia in other body parts. Combined forms can be segmental at the onset or can result from dystonia spread to or from the larynx. The aim of this study was to identify the main clinical and demographic features of adult-onset idiopathic LD in an Italian population with special focus on dystonia spread. METHODS: Data were obtained from the Italian Dystonia Registry (IDR) produced by 37 Italian institutions. Clinical and demographic data of 71 patients with idiopathic adult-onset LD were extracted from a pool of 1131 subjects included in the IDR. RESULTS: Fifty of 71 patients presented a laryngeal focal onset; the remaining subjects had onset in other body regions and later laryngeal spread. The two groups did not show significant differences of demographic features. 32% of patients with laryngeal onset reported spread to contiguous body regions afterwards and in most cases (12 of 16 subjects) dystonia started to spread within 1 year from the onset. LD patients who remained focal and those who had dystonia spread did not show other differences. CONCLUSIONS: Data from IDR show that dystonic patients with focal laryngeal onset will present spread in almost one-third of cases. Spread from the larynx occurs early and is directed to contiguous body regions showing similarities with clinical progression of blepharospasm. This study gives a new accurate description of LD phenomenology that may contribute to improving the comprehension of dystonia pathophysiology.

Dental Sealants. Part 2: Who should get dental sealants and when.

BACKGROUND: Despite the remarkable achievements in recent decades in oral prevention, sealants are still underused even if their efficacy is well documented and clinical practice guidelines are available in almost every developed country. The clinician should know who needs dental sealants and when, with particular focus on high risk patients and pre-school children.

Re-emergent tremor in Parkinson's disease: the effect of dopaminergic treatment.

BACKGROUND AND PURPOSE: Patients with Parkinson's disease (PD) with resting tremor may be affected by a tremor that appears after a varying latency while a posture is maintained, a phenomenon referred to as re-emergent tremor (RET). The aim of the study was to evaluate the occurrence and clinical features of RET in patients with PD tested off and on treatment, and to compare the effect of dopaminergic treatment on RET with the effect on resting and action tremor. METHODS: We consecutively enrolled 100 patients with PD. Patients were clinically evaluated 24 h after withdrawal of therapy (off-treatment phase) and 60 min after therapy administration (on-treatment phase). We collected the demographic and clinical data of patients with PD. The severity of the disease was assessed by means of the Hoehn and Yahr scale and Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale part III. We evaluated the latency, severity and body side affected both off and on treatment in patients with RET. RESULTS: Re-emergent tremor was present in 24% of the patients with PD off treatment and in 19% of the patients on treatment. Dopaminergic treatment reduced the clinical severity of RET. Dopaminergic treatment increased the number of patients with unilateral RET and reduced the number of those who had bilateral RET. RET and resting tremor responded similarly to dopaminergic treatment, whereas action tremor was less responsive. Patients with RET had milder motor symptoms than patients without RET both off and on treatment. CONCLUSIONS: Dopaminergic treatment modified RET occurrence, severity and body distribution. Dopaminergic depletion plays a role in the pathophysiology of RET.

Multidisciplinary approach to the treatment of double bilateral upper permanent incisors in a young boy.

BACKGROUND: A double tooth is a rare developmental anomaly referring to the fusion of two adjacent tooth buds or the gemination of a single bud. CASE REPORT: This case report describes the multidisciplinary approach to an 11-year-old patient with two double upper permanent incisors. The clinical intraoral examination showed a mixed dentition with bilateral double maxillary central incisors, molar Class I malocclusion and palatal ectopy of two lateral upper incisors. Computed tomography of the upper dental arch revealed the presence of double central incisors with two distinct roots. The clinical choice consisted of an innovative treatment including surgical, endodontic, orthodontic and restorative treatments. This management protocol produced good aesthetic, healthy and functional results that were stable also two years post-treatment.

Clinical heterogeneity in patients with idiopathic blepharospasm: A cluster analysis.

BACKGROUND: Idiopathic blepharospasm is a clinically heterogeneous condition. It is not known whether the various manifestations become manifest sequentially during the course of the disease or aggregate in separate clusters identifying subpopulations of patients. METHODS: Eighty-nine patients with idiopathic blepharospasm were assessed using k-means cluster analysis to identify relatively homogeneous groups on the basis of low-intragroup/high-intergroup differences across a set of selected variables. RESULTS: The results suggest that there may be three groups of patients. Group 1 included patients who had prolonged muscle spasms leading to complete rim closure associated with brief and/or prolonged spasms with incomplete rim closure, the most severe blepharospasm, and a greater tendency to spread to adjacent segments. Group 2 included patients characterized by prolonged spasms with partial rim closure, either alone or associated with brief spasms whereas Group 3 included patients with brief spasms with complete rim closure, the least severe blepharospasm, and the lowest tendency to spread. The severity of Group 2 blepharospasm was between that observed in Group 1 and Group 3, while the tendency to spread was similar to Group 3. The three groups did not differ for disease duration, age of onset, sex and other clinical features. The observation that inhibition of the R2 component of the blink reflex recovery cycle was more abnormal in Groups 1/2 2 than in Group 3 at least in part validates our classification. CONCLUSIONS: The present study suggests that blepharospasm patients may be classified in different subtypes according to the type of spasms, severity of the condition and tendency to spread.
