This commentary has the aim of presenting the 10 statements of the Chart, from a perspective of Occupational health and safety.

Evaluation of dental demands and needs of people experiencing homelessness in the city of Rome, Italy.

OBJECTIVE: Poor oral health and oral diseases are common among people experiencing homelessness. The aim of this study was to evaluate the dental demands and needs of a population of homeless persons in the city of Rome, Italy. PATIENTS AND METHODS: The clinical records of 165 homeless patients admitted between October 2020 and October 2021 to the dental service of the Primary Care Services of the Eleemosynaria Apostolica, Vatican City, were retrospectively reviewed. The service employed dentists to evaluate dental needs and oral conditions in patients experiencing homelessness. The main dental and oral pathological conditions were noted. RESULTS: One hundred and sixty-five records of homeless patients were included in the study. The sample consisted in 138 males (76.97%) and 27 females (23.03%) with a mean age of 46.9 years (range 7-85 years). Acute tooth pain was reported by 132 (80%) patients, 42 (25.45%) had edentulism or missing teeth and 18 (10.91%) patients had oral lesions. Both dental and oral pathologies were intercepted and managed in secondary healthcare facilities. CONCLUSIONS: Given the specific peculiarities of this vulnerable population, it is important to implement strategies that facilitate the access of persons experiencing homelessness to dental evaluation with a preventive and curative perspective.

Prevalence of molar incisor hypomineralization among school children in Rome, Italy.

Molar incisor hypomineralization (MIH) is a highly prevalent condition associated with increased caries experience, dental pain and treatment need. Aim of this study was to determine the prevalence and severity of MIH in a group of 7-8 years old primary school children living in Rome, Italy; and to assess the association with caries experience and possible perinatal risk factors. A survey has been conducted in the city of Rome, between April 2019 and March 2020 with a total of 49 primary schools and 176 2nd grade primary school classes and a total of 3611 children being involved. Of these, a subset of 346 children of 21 primary schools was selected for the epidemiological investigation. The prevalence of MIH was of 18.2%, with girls showing twice the probability of being subject to a mild-severe condition. Molar location was present in 71.4%, while location on both molar plus incisor was present in 28.6% of cases. The mean DMFT was 0.44 ± 0.78, "D" was 0.17 ± 0.58; the mean dmft was 1.7 ± 2.56, "d" was 1.32 ± 2.21. Female gender, caries experience, insufficient oral hygiene were risk factors. The incidence of MIH is increasing in the pediatric population. Knowledge about diagnosis and treatment options should be disseminated among dental professionals.

The cornea as a reference point in orthodontic diagnosing, a retrospective study.

Background: The aim of the study is to provide scientific evidence on the possibility of using the Corneal point a skin point for measu-rements that can be made on both standard and three-dimensional photographs. Also, we want to demonstrate the stability of corneal point during the growth, to use it as a reference point. Methods: A sample of 105 radiographs was reached. A descriptive and longitudinal statistical analysis was performed. Results: By data analysis we obtained more variability inter-subject of the millimetrically value of the SC plan. For this reason, we consi-dered the relationship between the SN and SC values and not a single value. In the cross-sectional study the T- test analysis did not show a different significant result of variations between SC and SN in both sexes; therefore, we considered these as unique sample. Conclusion: Longitudinal study has a major importance for to esta-blishing the age-related changes. By cross-selection and longitudinal analysis we obtained an overlapping trend of the SN and SC plan. As the SN plan has always been used as a reference plan for cephalometric measurements, although its variations in growth, it can be concluded that the SC plan can be considered equally a reference plan.

Gnathological and osteopathic treatments with digital evalua- tions before and after therapies: a case report of a patient with ehlers-danlos syndrome.

BACKGROUND: Ehlers-Danlos syndromes (EDS) are inherited connective tissue disorders, requiring specific care along with a multidisciplinary approach by an expert medical staff, as for both the diagnosis and the treatment management. Chronic generalized pain and musculoskeletal dysfunctions due to joint hypermobility are common traits. Temporomandibular disorders (TMDs) are among the most frequent complaints. The authors report the diagnostic and therapeutic management of an EDS subject. CASE PRESENTATION: A 33-year old woman with Ehlers-Danlos syndrome, hypermobile type, was clinically evalu-ated and treated. She underwent a gnathological therapy with an anterior repositioning splint and proprioception ex-ercises, and a physical rehabilitation through an osteopathic manipulation treatment (OMT). Technology - surface Elec-tromyography (sEMG) of masticatory muscles, T-scan and stabilometric platform- supported diagnostic and therapeutic phases, giving objective and quantifiable information on the patient's assessment before and after treatments. CONCLUSION: According to a targeted therapeutic strategy, both the gnathological and the osteopathic therapy proved to be effective in improving patient's symptomatology and functionality, as confirmed by digital findings.

Transport mechanisms in Co-doped ZnO (ZCO) and H-irradiated ZCO polycrystalline thin films.

In the present study, the electrical resistivity (ρ) as a function of the temperature (T) has been measured in polycrystalline ZnO, Co-doped ZnO (ZCO) and H irradiated ZCO (HZCO) samples, in the 300-20 K range. The achieved results show impressive effects of Co doping and H irradiation on the ZnO transport properties. The Co dopant increases the ZnO resistivity at high T (HT), whereas it has an opposite effect at low T (LT). H balances the Co effects by neutralizing the ρ increase at HT and strengthening its decrease at LT. A careful analysis of the ρ data permits to identify two different thermally activated processes as those governing the charge transport in the three materials at HT and LT, respectively. The occurrence of such processes has been fully explained in terms of a previously proposed model based on an acceptor impurity band, induced by the formation of Co-oxygen vacancy complexes, as well as known effects produced by H on the ZnO properties. The same analysis shows that both Co and H reduce the effects of grain boundaries on the transport processes. The high conductivity of HZCO in the whole T-range and its low noise level resulting from electric noise spectroscopy make this material a very interesting one for technological applications.

Knowledge of Emergency Management of Avulsed Teeth among Italian Dentists-Questionnaire Study and Next Future Perspectives.

(1) Background: In Italy, about one fourth of all schoolchildren experience a trauma to the permanent dentition. Management of avulsion trauma is challenging and requires adherence to clinical protocols. The aim of this study was to investigate the management knowledge of avulsed teeth among Italian dentists and to promote the guidelines' dissemination through the use of new social media. (2) Methods: The survey was carried out during the COVID-19 lockdown in Italy (March-May 2020). The questionnaire was sent anonymously to a total of 600 dentists. The questionnaire consisted of two parts. Part A-demographic and professional data and Part B-management of traumatic avulsion. (3) Results: The response rate was 50.6% and the mean fraction of correct responses was 0.524. Issues related to the therapeutic management of avulsed teeth were shown to be not well understood by the respondents. Professionals with qualifications in dentistry and those who declared to know the guidelines responded better, while other demographic and professional factors were insignificant. (4) Conclusions: Italian dentists' knowledge of the management of avulsion trauma should be improved. Educational programs and campaigns must be undertaken to improve their awareness and adherence to the Italian and international guidelines.

Impact of COVID-19 pandemic on otolaryngology, ophthalmology and dental clinical activity and future perspectives.

OBJECTIVE: Since the COVID-19 outbreak, otolaryngologists, ophthalmologists and dentists have been severely affected, both for the transmission routes and for the diagnostical and therapeutic procedures typical of these disciplines. MATERIALS AND METHODS: In this article, we discuss the transmission routes, the potential risk of contagion for patients and healthcare providers during procedures, and comment on the changes that will affect head and neck clinical practice in the future of outpatient and surgical activities. RESULTS: Otolaryngologists, ophthalmologists and dentists are at high risk for infection contagion and spread because they perform diagnostic and therapeutic procedures that generate aerosol and droplets thus facilitating virus transmission. Furthermore, examination involves close doctor-patient contact and otolaryngologists and dentists have to remove patient's protective devices during the visit. CONCLUSIONS: Special attention to prevention protocols for diagnostic and therapeutic procedures and the use of protective equipment is of utmost importance to limit contagion and prevent a new virus spread in the near future.

Subjects with temporomandibular joint disc displacement and body posture assessment via rasterstereography: a pilot case-control study.

OBJECTIVE: The possible relationship between temporomandibular disorders (TMDs) and body posture is still controversial. Rasterstereography has been introduced as a radiation-free, reliable and non-invasive method to analyze three-dimensional spinal posture. The aim of this case-control study is to evaluate, through rasterstereography, body posture parameters in a group of patients with reducible unilateral dislocation of the articular disc, compared to healthy volunteers. PATIENTS AND METHODS: Rasterstereographic recordings obtained were compared between the two groups with a paired t-student test. Furthermore, the relationship between Rasterstereographic recordings and clinical data in the TMD group were analyzed by means of multiple regression analysis. RESULTS: Only lateral deviation was statistically significant different between the two groups (rms VPDM Control group 40% > TMD group, p=0.02; 43% control group VPDM max > TMD group, p<0.02). In the TMD group, a significant relationship (p<0.05) was found out between lateral and rotational deviations of the column and muscular pain, therefore suggesting a possible overactivity of the masticatory muscles, especially of lateral pterygoids' bilaterally and the left masseter. CONCLUSIONS: Patients with reducible unilateral disc displacement showed limited postural alterations compared to healthy volunteers, only lateral deviations (VPDM rms and VPDM-max) were statistically significant (Π<0.05) between the two groups.

Muscular pattern in patients with temporomandibular joint disc displacement with reduction: an electromyographical assessment.

OBJECTIVE: Surface Electromyography of masticatory muscles (sEMG) is used as a tool to support diagnosis and treatment of Temporomandibular disorders (TMDs). The study aimed at examining jaw muscles pattern in individuals with temporomandibular joint disc displacement with reduction (TMJ/DDR). This sort of subjects was supposed to have a different muscular pattern compared to the control group. MATERIALS AND METHODS: Sixty-four women with unilateral TMJ/DDR and forty TMD-free women underwent a sEMG assessment of masticatory muscles. Descriptive statistics were performed. Student T-Test assessed differences between the two groups. Statistical significance was set at ρ < 0.05. RESULT: The t-test showed statistically significant results only in BAR and SMI scores (ρ value < 0,0001). The other measurements did not differ between the two groups. BAR index values of all healthy subjects were within the reference range. Almost the entire TMJ/DDR group had BAR index out of reference range and anteriorly placed. CONCLUSION: Women with TMJ/DDR showed an altered recruitment of the jaw muscles, with significant difference between the activity of the couple of temporalis and the one of masseters, compared to the control group. A lower chewing efficiency was found in the DDR group compared to the control one.

Dental Monitoring Application: it is a valid innovation in the Orthodontics Practice?

AIM: The aim of research is to show the effectiveness of 0.014X0.025 CuNiTi wires in self-ligating straight-wire appliance in the working time of 10 weeks, the treatments are monitored with the Dental Monitoring® Applications. A statistical significance analysis of the correspondence between the results of the first phase of fixed orthodontic treatment (alignment), according to the type of wires used, compared to the time (about 8 weeks) suggested by the manufactory house is therefore useful to fully understand the power of these arches in the orthodontic treatment. MATERIAL AND METHODS: The study provides for the recruitment of 35 cooperating patients with different degrees of crowding, all treated with Damon System(ORMCO), monitoring them through pictures, taken in the Dental Monitoring(DM®) sequence technique, as follows: Time0: Arch-Wire Insertion (0.014x0.025CuNiTi), Time1: Four Weeks, Time2: Eight Weeks, Time3: Ten Weeks. RESULT: The results obtained will be compared with records reported by manufactory house. Our results showed that the manufacture information does not correspond to the real efficiency of the device tested. Statistical Analyses performed by T test student. CONCLUSIONS: In Our experience, applying DM Application with self-ligating technique has reduced in term of number of appointments for each patient from 3 appointments in 10 weeks to 2 appointments, when the indirect bonding was effectuated and when we have inserted a 014X025 CuNiTi. This means that there is a reduction in the mean period of chair time, of material 'costs, number of visits; moreover, there is an increase in term of frequency of patient' s monitoring, resulting in a more precise evaluation of treatment by orthodontist. The limits of the present study are presented by the variable patient's compliance and by the small number of patients. This device is an instrument advantageous for the orthodontist's work. In literature, there are few articles inherent to Digital application Mobile, we will hope that this our experience represents a valid support to a major use of this application in the clinical practice.

Prevalence of oral disease and treatment types proposed to children affected by Autistic Spectrum Disorder in Pediatric Dentistry: a Systematic Review.

PURPOSE: To investigate the prevalence of dental caries and periodontal disease in children with ASD, and to analyse the necessity of treatment and the prevalence of using general anaesthesia in order to perform it. MATERIALS AND METHODS: A search was performed covering the last 10 years utilising the following databases: Pubmed, Scopus, Medline, BASE, Science Citation Index, Science Direct, Web of Science. Four reviewers evaluated each study. Review findings were summarised using the PRISMA Statement for reporting. Thirteen articles were included in this systematic review. RESULTS: When analysing the articles selected, the evidence turned out did not show a common DFMT and dmft for the groups of children affected by Autism Spectrum Disorder considered. When compared to group of unaffected children, groups of ASD children not always showed a higher prevalence of caries but always higher Periodontal Indexes (PI and GI), resulting in higher prevalence of periodontal disease. Where the treatment was performed and taken into consideration, there was a high incidence of necessity of General Anaesthesia due to the lack of collaboration of the children. CONCLUSION: The high prevalence of treatment under general anaesthesia and the often-reported negative behaviour evidence how there is a lack of protocols specifically designed for these patients, in order to better improve their collaboration and subsequently their oral health and so additional strategies for a preventive care should be applied for these patients.

Bisphosphonate-related osteonecrosis of the jaws and dental surgery procedures in children and young people with osteogenesis imperfecta: A systematic review.

BACKGROUND: Bisphosphonates (BPs) contrast the bone fragility and improve bone density in some metastatic cancers and bone diseases, such as Osteogenesis Imperfecta (OI). BPs use has been associated with osteonecrosis of the jaws (BRONJs) in adults needing for invasive dental procedures. AIM: To conduct a systematic review on BRONJ occurrence after dental surgery in paediatric population under BPs therapy for OI, so as to identify the pre-surgical protocols adopted. DESIGN: According to PRISMA guidelines, Pubmed, Web of Science (WoS) and Cochrane were investigated on September 2018, and re-checked on July 2019. Inclusion criteria were English-language papers on children/young adults (until 24 years old) reporting dental/oral surgery procedures. RESULTS: Totally, 60 articles were found. After title/abstract reviews and duplicates exclusion, 22 eligible titles underwent full-text evaluation. Finally, 10 studies were included. CONCLUSIONS: The lack of BRONJ occurrence in paediatric population suffering OI and treated with BPs, was confirmed, but the reasons are still debated, being the BPs therapies and the surgical strategies various and not standardized. Longitudinal studies should evaluate what happens to those former children once adult, to evaluate the delayed BRONJs onset associated with the occurrence of comorbidities during the adulthood.

Epidemiological characteristic of Orofacial clefts and its associated congenital anomalies: retrospective study.

BACKGROUND: To evaluate the relationship between gender, ethnicity/citizenship, clinical phenotype, total prevalence, and the various congenital malformations associated with oral clefts (OC) in Italy across the period 2001-2014. METHODS: A retrospective analysis (2001-2014) was conducted based on the National Congenital Malformation Registries network of Italy (Emilia-Romagna Registry of Birth Defects [IMER] and Registro Toscano Difetti Congeniti [RTDC]), which were analyzed to investigate time trends, geographical/ethnic clusters, topography, sex ratio, and associated congenital anomalies of OC phenotypes. RESULTS: Among 739 registered cases, 29.8% were syndromic or had multi-malformed associated anomalies, compared with 70.2% having isolated orofacial cleft. Cleft lip (CL) was observed in 22%, cleft palate (CP) in 40%, and cleft lip and palate (CLP) in 38% of live births, stillbirths, and terminations of pregnancy for fetal anomaly cases. Other associated conditions were major anomalies of cardiovascular defects (39%), followed by defects of the limbs (28%), neuroectodermal defects (23%), and urogenital malformations (10%). Male-to-female sex ratio was 1:1.14 in CP, 1.22:1 in CL, and 1.9:1 in CLP. Foreigners were represented by 29% from Southeast Asia, 25% from Balkans, 25% from North-Central Africa, 9% from the East, 7% from Western Europe, and 5% from South America. Total prevalence of OC cases ranged from 0.9 (RTDC) to 1.1 (IMER) of 1000 births. CONCLUSIONS: This retrospective study provides a population-based, clinical-epidemiological description of the orofacial cleft phenomenon. As a relatively frequent congenital malformation, its social and economic impact is worthy of further study. These abnormalities can cause significant problems that may be solved or minimized by early diagnosis and treatment.

Implant placement in oral squamous cells carcinoma patients treated with chemoradiotherapy: "Sapienza Head and Neck Unit" clinical recommendations.

OBJECTIVE: To date, the treatment of patients affected by head and neck squamous cell carcinoma (HNSCC) is highly challenging for clinicians. Possible therapies are surgical resection of the tumor mass, radiotherapy, chemotherapy or, more often, a combined treatment that inevitably affects both normal and tumor cells. Consequently, patients' anatomy and functions become reduced or altered. Nowadays the functional restoration is significantly improved thanks to the innovation in prosthetic rehabilitation and in radiotherapy. The current IMRT (Intensity Modulated Radiation Therapy) allows planning adequate treatments evaluating different tissues' involvement and radiation dosage. It is possible to define the most suitable sites for implant insertion, using data provided by dose-volume histogram (DVH). This study aims to illustrate the idea of obtaining a unique CT image by blending radiation-planning CT and Cone Beam CT. PATIENTS AND METHODS: Five patients among 54 candidates were selected for this study. Selection criteria were: good general health (PS0-1), age between 18 and 72 years, absence of metastatic disease or local recurrence, disease-free interval of at least 18 months. Radiation planning CT scan and maxillo-facial CT Cone Beam of every patient were overlapped and merged. Only one CT for every evaluated patient was obtained in order to plan the most suitable areas for implant placement. RESULTS: The placement of 10 implants in 5 patients was programmed using the explained method. Patients (all male) were aged between 48 and 72 years old, with a median age of 64.4 years. In every case of this study, a modification of the initial program of implant placement was necessary. The new imaging method we are proposing was able to provide information about radiation isodoses received in the planned osseointegrated implants' positions. CONCLUSIONS: This new method allows operators to correct their own therapy plans and choices, customizing the treatment plan on the actual condition of the patient. Moreover, it makes all the rehabilitation process safer and can reduce the risk of failure, side effects and inconveniences for the patients.

Assessment of Masticatory and Cervical Muscles' Thickness by Ultrasonography in Patients with Facial Asymmetry.

OBJECTIVE: The aim of this study was to determine the relationship between the thickness of masticatory and cervical muscles (temporalis, masseter and sternocleidomastoid) and facial asymmetries in young patients. METHODS: 21 subjects were selected, through a detailed anamnesis and clinical examination, in order to assess the normality of oral tissues, the presence of normal occlusion, the absence of alteration in tooth dimensions and of congenital or developmental anomalies of lips, mouth or face. RESULTS: The present investigation showed that temporalis, masseter and sternocleidomastoid muscles in untreated and growing individuals with facial asymmetries are thinner on the omolateral side when compared with controlateral normal side, but in the untreated one this value is more statistically significantly. CONCLUSIONS: In conclusion, the cervical muscle's thickness resulted increased in young patients Ultrasound is beginning to be recognized to have potential use in dentistry as a safe, noninvasive, comfortable and cost-effective adjunct to diagnosis by producing high-resolution images more easily than magnetic resonance (MRI) and computed tomography (CT) (27-kubo).

Using of modified rapid palate expander with miniscrews in a patient affected by ectodermic dysplasia.

OBJECTIVES: To show the orthodontic treatment in a 8-year-old patient affected by Ectodermal Dysplasia (hypohidrotic type) and presenting multiple agenesiae, contraction of the maxilla and skeletal Class III malocclusion. STUDY DESIGN: Because of both oligodontia of primary and secondary dentition and no good retention and anchoring, a hybrid modified rapid palatal expander (RPE) was used. It presented dental anchoring with two bands on first upper molars and skeletal anchoring with two miniscrews in the anterior palate. The project included the use of a CBTC for the bone examination and precise silicon dental impression for the insertion of miniscrews. RESULTS: The procedure was successful and the patient solved the expansion in few days, so RPE has been embedded throughout 6 months in order to develop the bone at the median suture. CONCLUSIONS: This case report can be considered as a valid example for approaching patients affected by Ectodermal Dysplasia with multiple agenesiae and palatal contraction because of the difficult retention.
