RESUMO
AIM: The primary goal of the present comprehensive systematic review is to assess the treatment results attained through PSIO in individuals with NSCLP, as well as to explore its effectiveness. This will be accomplished by examining a range of existing published studies that focus on patient groups who have undergone PPIO. MATERIALS: A comprehensive search strategy was devised by a single author for each database without language restrictions. The databases searched were PubMed, Cochrane library Google Scholar, Web of Science and Scopus. The search period was limited to the years 2001 to 2023. Duration and study design filter was used. Furthermore, conference proceedings, abstracts, and reference lists of relevant studies were sought to obtain additional records. CONCLUSION: The examined protocols for passive presurgical infant orthopaedics (PPIO) in individuals with CLP typically did not reveal notable treatment outcomes when compared to a lack of treatment across a range of domains. These domains encompass feeding patterns, facial aesthetics, maxillary dentoalveolar factors, cephalometric measurements, speech and language-related aspects, dental arch alignments, economic assessments, as well as occurrences of adverse effects or complications associated with applied appliances or procedures.
RESUMO
AIM: This study aims to gauge the level of awareness among parents about the importance, timing, and benefits of early orthodontic assessments for their children. MATERIALS: A questionnaire consisting of 12 questions was created through Google Forms to measure the knowledge about early orthodontic treatment and consultation with the parents of 1821 patients aged 6-11 years admitted to the paediatric service of a training and research hospital and filled out by the parents. The distribution of variables was examined with the Shapiro-Wilk normality test; the independent t test was used in the comparison of paired groups of normally distributed variables; and the chi-square test was used in the comparison of qualitative data. A stepwise logistic regression analysis was performed to determine the effective factors for consultation with the orthodontist. CONCLUSION: The present study found a positive relationship between parents' education and monthly financial income and their knowledge of malocclusions for early orthodontic treatment. Conversely, there was a negative correlation between the number of children parents had and their awareness of malocclusions. The early identification of malocclusions allows orthodontic problems to be corrected with less complex treatment methods.
RESUMO
AIM: To explore the relationship between parents' education levels, children obesity, children oral health and oral-related sleep disorders. BACKGROUND: Prevention of oral diseases in children is important for their long-term health. Parents play a crucial role in the health and wellness of their children. As such, it is important for parents to be well-informed about the importance of their children's oral health, as well as the steps they can take to ensure that their children receive the best possible care. METHODS: Observational cross-sectional study. At the time of enrollment data regarding parents' employment status and parents' education level were collected. We also collected BMI and anamnestic data regarding the presence or not of oral-related sleep disorders in the last 3 months: snoring, chronic mouth breathing, sleep bruxism. Oral health was also evaluated for each subject through the DMFT (decayed, missing and filled teeth) index. CONCLUSION: Parents' education levels influence several health outcomes, including oral health and the risk of obesity. In turn, obesity can represent a risk factor for oral-related sleep disturbances. Parents play a crucial role in the health and wellness of their children. As such, it is important for parents to be knowledgeable about the importance of their children's health, as well as the steps they can take to ensure that their children receive the best possible care.

AIM: The aim of the present study was to evaluate the cephalometric changes in growing Class II patients with increased vertical dimension treated with cervical or high-pull headgear, by using an untreated control group with similar skeletal characteristics. MATERIALS: From the initial sample, 56 patients satisfied the inclusion and exclusion criteria; 20 patients were treated with cervical headgear (CHG), 15 with high-pull headgear (HHG), and 21 were not treated (CG). Cephalograms were available for each subject at baseline (T1) and after treatment/observation time (T2) for the three groups. A total of 17 measurements were taken on the lateral head films. Group comparison among CHG, HHG and CG was done using ANOVA test. CONCLUSION: In Class II high-angle growing patients, cervical headgear seems to be preferred in the correction of maxillary protrusion, molar relationship and increased anterior facial height. Extrusion of the upper molar may favour forward repositioning of the mandible and clockwise rotation in Class II patients with increased vertical dimension.

The aim of this study was to evaluate whether piezoelectric bone surgery (PBS) for impacted lower third molar extraction reduces the surgical time and risk of intra- and postoperative complications in comparison with conventional rotary instruments. This meta-analysis followed the PRISMA guidelines and was registered in the PROSPERO database. The PubMed, Embase, Scopus, and OpenGrey databases were screened for articles published from January 1, 1990 to December 31, 2018. Selection criteria included randomized controlled trials (RCTs) comparing PBS with conventional rotary instruments for impacted lower third molar extraction and reporting any of the clinical outcomes (intra- and postoperative complications and duration of surgery) for both groups. A risk of bias assessment was performed using the Cochrane Collaboration tool. A meta-analysis was performed, and the power of the meta-analytic findings was assessed by trial sequential analysis (TSA). Strong evidence suggests that PBS prolongs the duration of surgery and low evidence suggests that PBS reduces postoperative morbidity (pain and trismus) in comparison with rotary instruments. Data were insufficient to determine whether PBS reduces neurological complications and postoperative swelling in comparison with burs.

OBJECTIVE: To evaluate the different behavior of two different human adult adipocytes derived stem cells (hASCs) during proliferation and osteogenic differentiation. PATIENTS AND METHODS: Human adult adipocytes stem cells (hAT-SCs) from visceral (hAV-SCs) and subcutaneous (hAS-SCs) sites were obtained after surgery procedures of seven patients. All samples were fully investigated and the different proliferation rates were evaluated. All MSCs clusters were cultured with an osteogenic and adipogenic differentiation medium. Homogeneous pools of Mesenchymal Stem Cells (MSCs) were confirmed by Flow-Cytometry Analysis (FACS) and Spectrophotometric Assay. The differentiated cells were eventually assessed for the expression of Alkaline Phosphatase (ALP), Alizarin Red (AR) and Oil Red-O (OR-O) detection, and analyzed by the Spectrophotometric Assay. After osteogenic differentiation, the cell clusters were incubated and analyzed with Real Time-Polymerase Chain Reaction (qRT-PCR) and fluorescence microscopy. RESULTS: The FACS analysis performed on hAT-SCs confirmed the homogenous presence of MSCs in all samples. The ALP, AR stain confirmed the osteogenic differentiation capacity of MSCs towards osteoblast-like-cells. The colorimetric cell metabolic activity (MTS) assay showed an increase in the proliferation rate with different values in both sets hAS-SCs vs. hAV-SCs. CONCLUSIONS: These in vitro findings of both hAS-SCs and hAV-SCs suggested an important role of these stem cells for future clinical use in bone regeneration. Indeed, the final outcomes suggested a better performance of cells coming from subcutaneous adipose tissue vs. those from visceral fat tissue.

The objective of this study was to compare the efficacy of celecoxib and ibuprofen in reducing postoperative sequelae following the surgical removal of impacted mandibular third molars. Ninety-eight subjects who needed surgical extraction of an impacted mandibular third molar were selected for the study. All subjects were randomly allocated to receive one of the following treatments twice a day for 5days after surgery: placebo (n=32), ibuprofen (n=33), or celecoxib (n=33). The primary outcome chosen was postoperative pain, which was evaluated using the visual analogue scale (VAS) score recorded by each patient. The secondary outcomes chosen were changes in postoperative swelling and maximum mouth opening values compared to preoperative ones. Compared to placebo, treatment with celecoxib and ibuprofen resulted in improvements in the primary outcome. Furthermore, when compared to the other groups, patients in the celecoxib group showed a significant reduction in postoperative pain scores at 6h (P<0.001), 12h (P=0.011), and 24h (P=0.041) after surgery. Regarding swelling and maximum mouth opening values, there were no significant differences between the groups at each follow-up session. This study demonstrated that treatment with celecoxib decreased the incidence and severity of postoperative pain following third molar surgery compared to ibuprofen and placebo.

BACKGROUND: Class II malocclusion is the most common sagittal skeletal discrepancy, with a prevalent skeletal pattern of mandibular retrusion. The correction of mandibular retrusion with functional removable appliance needs a good patient's compliance; for this reason, some clinicians prefer to use no compliance apparatus. OBJECTIVE: Objective of the present therapy note is to demonstrate that the use of no compliance apparatus can provide a good correction of skeletal class II malocclusion. METHODS: In the present study, authors report a therapy note referred to a 10 years old patient, woman, affected by Class II, with mandibular retrusion and deep bite, treated in 2013 at the Dep. of Orthodontics of Messina University. An orthodontic treatment has been planned with the aim of stimulating mandibular growth; an Herbst appliance with a cantilever design, bonded on first maxillary and mandibular molars, has been used. After eleven months of functional therapy a bilateral molar class I have been obtained. RESULTS: In the therapy note proposed, authors obtained a resolution of mandibular retrusion, a correction of overjet, overbite and dental crowding in both arches, and a bilateral molar and canine class I has been achieved. CONCLUSION: Herbst appliance seems to be efficient in the correction of II Class Malocclusion, independently from patient's cooperation; moreover , early correction of Class II malocclusion with functional appliances produces several clinical advantages.
RESUMO
Numerous studies have established statistical associations of the IL-1 gene cluster polymorphisms with various inflammatory diseases. Deriving from that, the present study was intended to determine whether single-nucleotide polymorphisms (SNPs) in these gene are also associated with periodontal disease in a Linkage disequilibrium analysis. This investigation also created two haplotype blocks, both consisting of two different SNPs. Recent theoretical analyses indicate that research with an interpretation of periodontal disease as a complex, oligogenic disorder, with IL-1 genetic variation contributes an important but not exclusive influence on disease risk. Further studies are needed to confirm these results and to understand the mechanisms behind the observed association between IL-1 SNPs and periodontal disease.

Pseudoaneurysm of the internal maxillary artery due to a traumatic event is a rare condition. Pseudoaneurysms are usually directly produced by arteries break with extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. Then, this sac gradually expands and can be damaged. It is rare to see pseudoaneurysms of IMA. They are usually associated with fracture of the neck of the mandible. To the best of our knowledge the pseudoaneurysm of the internal maxillary artery related to maxillofacial trauma is an event extremely rare in the literature and if not quickly managed can lead to the patient's death. This case underlines how the close cooperation between surgeons and radiologists results in a quick diagnosis and management of such pathological events.
RESUMO
Aim. The aim of this study was to assess the success and the survival rate of dental implants placed in augmented bone after sinus lifting procedures. Material and Methods. 31 patients were mainly enrolled for a residual upper jaw crest thickness of 3 mm. CBCT scans were performed before and after the augmentation technique and at the follow-up appointments, at 3, 6, 12, 24, and up to 60 months. The follow-up examination included cumulative survival rate of implants, peri-implant marginal bone loss, and the height of sinus floor augmentation. Results. This retrospective study on 31 patients and 45 implants later inserted in a less than 3 mm crest showed excellent survival rates (99.5%), one implant was lost before loading due to an acute infection after 24 days, and two implants did not osteointegrate and were removed after 3 months. The radiological evaluation showed an average bone loss of 0.25 mm (±0.78 mm) at the first follow-up appointment (3 months) up to 0.30 mm (±1.28 mm) after 60-month follow-up. Conclusion. In this study it was reported how even in less than 3 mm thick crest a transcrestal technique can predictably be used with a long-term clinical and radiological outcome, giving patients excellent stability of the grafted material and healthy clinical results.
RESUMO
Custom-cast posts and cores are usually used to treat endodontically treated teeth. However, several researches have underlined how these devices may be a much higher elastic modulus than the supporting dentine and the difference in the modulus could lead to stress concentrating in the cement lute, leading to failure. The role of the cement seems to play a fundamental role in order to transfer the strength during the chewing phases. Aim of this research is to record the rate of cytotoxicity of five different dual-cured resin cements used for fiber posts cementation. We tested the cytotoxicity of this five materials on MG63 osteoblast-like cells through two different methods: MTT ([3-4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide succinate) assay which tests for mitochondrial enzyme activity(6) and xCELLigence® system.
RESUMO
AIM: The aim of this study was to evaluate the oral health status in patients with vascular dementia (VaD). Moreover, the association of the disease severity and the patients' cognitive and functional impairment with the oral findings have been recorded. METHODS: The study was directed on the study group (86 VaD patients) and the control group (82 healthy volunteers of the same age) from the IRCSS Neurolesi Bonino-Pulejo in Messina, Italy. Cognitive status was evaluated with the MMSE scoring system. Oral parameters, such as decaying, missing, filled teeth (DMFT) index, plaque index (PI), periodontal probing depth (PPD) and bleeding on probing (BOP) were evaluated in all patients. Denture condition and denture-induced stomatitis were also analysed. The frequency of untreated caries, periodontal diseases and missing teeth of the Study Group was significantly higher than in Control Group. RESULTS: Particularly, VaD patients presented higher number of decayed teeth and deeper periodontal pockets. Decreased cognitive functions in VaD patients have been demonstrated to result in a decline of denture care and increased denture-related mucosal lesions. CONCLUSION: These results underlined that clinicians should direct high attention to oral hygiene of patients with VaD in order to prevent the evolution of those pathologic dental and periodontal conditions, especially in patients with decreased cognitive functions.

PURPOSE: The aim of this investigation was to assess bone healing of sinus lift procedure in which the augmentation has been performed by using calcium sulphate like bone substitutes. The methods of this investigation how the use of Cone Beam Computed Tomography (CBCT) may be a valid instrument to support reconstructive surgery of the jaws. PATIENTS AND METHODOLOGY: 25 Patients presented large bone defects after tooth extractions located in the upper jaw posterior area. Vertical bone volume was assessed by CBCT examinations before and about six months after sinus lift surgery. RESULTS: Examined defects treated with sinus lift surgery and evaluated by CBCT showed a strong increasing on the bone volume at 6 months follow up control. CONCLUSION: Calcium sulphate application in sinus lift surgery represent a safe and predictable option in the place of autologous bone. Therefore the application of CBCT investigation may give the clinicians the opportunity of evaluating with high precision value, the consistence of the bone defects before the surgery.
RESUMO
Prosthetic rehabilitation of total edentulous jaws patients is today a common technique that clinicians approach in their daily practice. The use of dental implants for replacing missing teeth is going to be a safe technique and the implant-prosthetic materials give the possibility of having long-term clinical success. Aim of this work is to evaluate the mechanical features of three different prosthetic retention systems. By applying engineering systems of investigations like FEM and von Mises analyses, how the dental implant material holds out against the masticatory strength during the chewing cycles has been investigated. Three common dental implant overdenture retention systems have been investigated. The ball attachment system, the locator system, and the common dental abutment have been processed by Ansys Workbench 15.0 and underwent FEM and von Mises investigations. The elastic features of the materials used in the study have been taken from recent literature data. Results revealed different response for both types of device, although locator system showed better results for all conditions of loading. The data of this virtual model show all the features of different prosthetic retention systems under the masticatory load. Clinicians should find the better prosthetic solution related to the patients clinical condition in order to obtain long-term results.

The computer-guided flapless surgery for implant placement using stereolithographic templates is going to be considered a daily practice technique. The advantages of this kind of surgery are related with its no flap opening, with the precision of the implant positioning and with the possibility of having a quick rehabilitation and low post-surgical discomfort. The introduction of digital planning programs has made it possible to place dental implants in preplanned positions and being immediately functionally loaded by using prefabricated prostheses. This case presented a 12-year follow-up of a maxillary prosthesis supported by dental implant immediately loading and positioned with the first kind of guided flapless surgery technique. Aim of this paper was to report how the guide surgery implant position technique can be considered a predictable and safe technique giving the surgeon excellent long-term results.

Oral squamous cell carcinoma (OSCC) is one of the most debilitating cancers in the world and while its causes have been heavily researched, the outcome remains grim. Most of these cancers are identified in the late stage and as a result treatment options are limited. Therefore, researchers have focused their efforts on recognizing and identifying dysplastic tissue that has an increased chance of progressing to cancer. Research has begun to look at cell cycle dysfunctions and in particular, aberrant protein functions as a way of identifying the cellular mechanism at fault. The overexpression of a group of regulatory proteins called cyclins has been demonstrated in many types of dysplasia and carcinomas. Although researchers have identified several different types of cyclins as potential culprits, we chose to focus our study primarily on the overexpression of cyclin A. While most research on oral dysplasia and OSCC has been focused on cyclin D, studies have been done on cyclin A. While the etiology of oral dysplasia/SCC appears to be multifactorial, we chose to compare our results with those of similar studies performed across the globe. The social factors, such as the increased use of tobacco that may have contributed to our results, were compared with similar studies performed in Europe and Asia. While our results were remarkably similar and demonstrated a link between the overexpression of cyclin A in oral dysplasia, there exists some differences and thus may require a multicenter, longitudinal study.

The rehabilitation of edentulous patients is today a challenge for the clinicians. The healthy of the hard and soft issue may be considered a fundamental element for having long-term results. The dental implant progresses about the predictable and safe results made this technique chosen from a large group of practitioners. However some problems related intra-operative and postoperative conditions may create discomfort on the patients and consequently to the clinician. The unfavourable results are often related to the bone tissue quality but sometime the dental implant shape and the prosthesis framework may undergo to technical difficulties. The purpose of this work is, through the use of appropriate FEM models, to analyse the effect of all these parameters in the construction of a prosthesis type "Toronto", evaluating all the surgical and prosthetic components in order to direct the choices made by the surgeon and to optimize the distribution of loads reducing the patient's discomfort and having a long term clinical success.
RESUMO
OBJECTIVES: The aim of this study was to measure the Oral Health-Related Quality of Life (OHRQoL) before and after a prosthodontic implant therapy so to determine the physical and psychological impact of implant-supported fixed partial dentures (IFPD) rehabilitation among edentulous patients. METHODS: 50 partially edentulous patients aged 40-70 years, treated with IFPD, completed the OHRQoL questionnaire before the implant surgery (Time 0) and 2 years after their whole implant-prosthetic rehabilitation (Time 1). The questionnaire was proposed in a short version of Oral Health Impact Profile (OHIP-14, range 0-56) and analyzed through the 'additive method'. We evaluated statistical mean, standard deviation, median, variance and mode of all OHIP-14 domains and the statistical significance about oral changes at Time 0 and Time 1 using the Chi-square test (p-values < 0.05). RESULTS: Patients reported significant changes in mean OHIP scores (Time 0: 2.15; Time 1: 0.65; p < 0.01). The most prevalently affected domain was "functional limitation", followed by "psychological discomfort" and "physical pain". There were no significant differences dependent on age, gender and antagonistic teeth (p > 0.05). Patients with I and IV Kennedy's class edentulism showed better improvement (p < 0.05). CONCLUSIONS: Preoperative and post-treatment assessments of OHRQoL exhibited significant differences. The IFPD treatment had a positive effect on the OHRQoL, which improved better in patients with I and IV Kennedy's edentulous class.
RESUMO
BACKGROUND: Stevens-Johnson syndrome (SJS) is a rare genetic disorder. The syndrome presents with severe purulent conjunctivitis, stomatitis with mucosal necrosis, and purpuric macules. This syndrome is associated with hypersensitive reaction usually stimulated by infection, vaccination, systemic diseases, physical agents, foods or drugs. However, only few cases reported can be related to infectious agents, but the causative role of infectious microorganisms seems relevant in paediatric patients. Authors want to underline the positive response of a new way of therapy by immunoglobulin injection. CASE REPORT: This case describes a 10-year-old girl with several erosions disseminated in the oral cavity mucosa. The girl had skin erosions that led to the clinical diagnosis of SJS. The past medical history of the patient revealed that those symptoms occured every 6 months over the last 2 years with 2 consecutive weeks of acute manifestations. At that moment, the paediatrician decided for cortisone administration in order to manage the acute symptoms, but after 6 months a new acute episode was observed. For this reason the patient was referred to the Department of Genetics and Immunological Paediatrics. TREATMENT: Oral ulcers had been topically treated with an oral balance gel. Intravenous injection of immunoglobulin was then applied and the patient was discharged after 5 days of treatment with the total symptoms in remission. FOLLOW-UP: The patient was followed up 3 monthly over the next 24 months. At that time no relapse of the SJS was observed. CONCLUSION: The seriousness of this condition imposes a prompt recognition. Paediatric dentists should recognise the clinical signs of possible SJS as soon as possible in order to perform a quick diagnosis and initiate treatment.
