Pediatric Obstructive Sleep Apnea Syndrome: Emerging Evidence and Treatment Approach.

ScientificWorldJournal 2021 23;2021:5591251. Epub 2021 Apr 23.

Department of Surgical, Medical and Molecular Pathology and Critical Area, Dental Clinic, University of Pisa, Pisa, Italy.

OSA pediatric subjects suffer from episodes of upper airway obstruction that can be partial or complete, with atypical sleep patterns and blood-gas level alteration. If poor treated and/or diagnosed, it can cause cardiovascular disease, learning difficulties, behavioural issues, and retardation of growth. In the literature, there are conflicting evidence about OSA assessment and treatment in pediatric age, so the aim of this paper is to highlight the multidisciplinary approach in the management of sleep disorders, stressing the role of the pediatric dentist in both diagnosing and treating the OSAS in children, according to the current evidence of the treatment options effectiveness of the syndrome itself. . Scientific evidence shows that OSAS management requires a multidisciplinary approach in order to make an early diagnosis and a correct treatment plan. The orthodontic treatment approach includes orthopedic maxillary expansion and mandibular advancement using intraoral appliances. Hence, the orthodontist and the pediatric dentist play an important role not only in early diagnosis but also in the treatment of pediatric OSAS.

Development and validation of the Italian version of the 'Parental Perceptions of Silver Diamine Fluoride Dental Color Changes' questionnaire.

Int J Paediatr Dent 2021 May 12. Epub 2021 May 12.

Department of Biomedical and NeuroMotor Sciences (DiBiNeM), Unit of Dental Care for Special Needs Patients and Paediatric Dentistry, University of Bologna, Bologna, Italy.

Background: The original English version of the questionnaire 'Parental Perceptions of SDF's 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.

Experimental Evaluation of Aerosol Production after Dental Ultrasonic Instrumentation: An Analysis on Fine Particulate Matter Perturbation.

Int J Environ Res Public Health 2021 03 24;18(7). Epub 2021 Mar 24.

Hygiene and Epidemiology Unit, Department of Translational Research and the New Technologies in Medicine and Surgery, University of Pisa, 56126 Pisa, Italy.

Aerosol production represents a major concern during the majority of dental procedures. The aim of the present study is to investigate the dynamics of aerosol particles after 15 min of continuous supragingival ultrasonic instrumentation with no attempt of containment through particle count analysis. Eight volunteers were treated with supragingival ultrasonic instrumentation of the anterior buccal region. A gravimetric impactor was positioned 1 m away and at the same height of the head of the patient. Particles of different sizes (0.3-10 µm) were measured at the beginning of instrumentation, at the end of instrumentation (EI), and then every 15 min up to 105 min. The 0.3-µm particles showed non-significant increases at 15/30 min. The 0.5-1-µm particles increased at EI ( < 0.05), and 0.5 µm remained high for another 15 min. Overall, all submicron aerosol particles showed a slow decrease to normal values. Particles measuring 3-5 µm showed non-significant increases at EI. Particles measuring 10 µm did not show any increases but a continuous reduction ( < 0.001 versus 0.3 µm, < 0.01 versus 0.5 µm, and < 0.05 versus 1-3 µm). Aerosol particles behaved differently according to their dimensions. Submicron aerosols peaked after instrumentation and slowly decreased after the end of instrumentation, whilst larger particles did not show any significant increases. This experimental study produces a benchmark for the measurement of aerosol particles during dental procedures and raises some relevant concerns about indoor air quality after instrumentation.

Application of IBM Watson to Support Literature Reviews: A Preliminary Experience in Restorative Dentistry.

Stud Health Technol Inform 2020 Jun;270:1201-1202

Università degli Studi di Trieste, Trieste, Italy.

Literature reviews are crucial in the choice of the best personalized material type and restauration type in restorative dentistry. We developed an IBM-Watson based system to support literature search for restorative dentistry, and compared its results to a literature search performed by a trained professional. We found that our system could assist the researcher in performing a literature review, but the grounding semantic model needs to be refined in order to provide more extensive results.

Simplified basic periodontal examination in adolescents before and after a tailored treatment dental program.

Minerva Stomatol 2020 Apr;69(2):72-78

Unit of Pediatric Dentistry, Department of Surgical, Medical, Molecular Pathology and Critical Area, University of Pisa, Pisa, Italy.

Background: The aim of this study was to evaluate the effectiveness of a tailored treatment dental program in adolescents in combination with a professional oral hygiene.

Methods: Ninety-three adolescents (43 males and 50 females; mean age: 14±1.1 years) were included in this study and Plaque Index (PI) and simplified basic periodontal examination (BPE) were measured for each patient at T0 (screening) and at T1 (after 30 days). At T0 a professional dental hygiene treatment was performed and a tailored oral hygiene instruction protocol was adopted. All data were statistically analyzed using Student's t-test and the level of significance was set at P<0.05.

Results: A statistically significant decrease of PI was found from T0 (2.3±0.6) to T1 (0.9±0.3) (P<0.05). Moreover, also a significant decrease (P<0.05) of BPE was observed after 30 days. Girls exhibited a higher significant BPE index improvement (0.47±0.2) in comparison to boys (0.3±0.1) at the end of the follow-up (P<0.05).

Conclusions: A tailored oral hygiene instruction protocol has resulted in a decreased plaque accumulation and gingival inflammation.

Investigation of Clinical Characteristics and Etiological Factors in Children with Molar Incisor Hypomineralization.

Int J Dent 2018 9;2018:7584736. Epub 2018 May 9.

Department of Surgical, Medical, Molecular Pathology and Critical Area, Dental and Oral Surgery Clinic, Unit of Pediatric Dentistry, University of Pisa, Via Savi 10, 56126 Pisa, Italy.

Aim: The purpose of the present study was to evaluate the clinical defects and etiological factors potentially involved in the onset of MIH in a pediatric sample.

Methods: 120 children, selected from the university dental clinic, were included: 60 children (25 boys and 35 girls; average age: 9.8 ± 1.8 years) with MIH formed the test group and 60 children (27 boys and 33 girls; average age: 10.1 ± 2 years) without MIH constituted the control group. Distribution and severity of MIH defects were evaluated, and a questionnaire was used to investigate the etiological variables; chi-square, univariate, and multivariate statistical tests were performed (significance level set at < 0.05).

Results: A total of 186 molars and 98 incisors exhibited MIH defects: 55 molars and 75 incisors showed mild defects, 91 molars and 20 incisors had moderate lesions, and 40 molars and 3 incisors showed severe lesions. Univariate and multivariate statistical analysis showed a significant association ( < 0.05) between MIH and ear, nose, and throat (ENT) disorders and the antibiotics used during pregnancy (0.019).

Conclusions: Moderate defects were more frequent in the molars, while mild lesions were more frequent in the incisors. Antibiotics used during pregnancy and ENT may be directly involved in the etiology of MIH in children.
