Aim. The aim of the study is to evaluate the therapeutic efficacy of a probiotic containing Lactobacillus reuteri DSM 17938 and Lactobacillus reuteri ATCC PTA 5289 in a sample of adult subjects affected by chronic periodontitis, associated with the periodontal treatment of Scaling and Root Planing (SRP).
Methods. The enrolment of 40 patients, aged between 18-70 years (mean age 46.55±14.33), was carried out at Department Diagnosis, Hygiene and Oral Prevention, University of Rome “Tor Vergata”, Rome, Italy. The subjects were assessed at baseline (T0) and after 1 month from the SRP (T1). The periodontal evaluation included: last data of Supportive Periodontal Therapy (SPT), Bleeding on Probing (BOP), Pocket Probing Depth (PPD), Clinical Attachment Level (CAL).
The sample of the subjects was randomly divided into two groups: Group 1 (case group), who received the probiotic, and Group 2 (control group).
Statistics. A randomized, single centre, controlled, parallel-group clinical study was conducted. Chi-Square test was used to evaluate statistical differences between gender and Groups. The Anova’s one-way analysis and Paired Sample t-test were applied to interpret the changes observed between the groups and in pre and post probiotic assumption for the clinical variables. The significance level was accepted 0.05. All statistical analyses were performed with the SPSS package.
Results. 40 patients aged between 18 and 70 years, with mean age of 46.55±14.33 were analysed. The Groups 1 and 2 were homogeneous, equal distributed for sex (p=0.21) and last data of SPT (p=0.09).
There was a statistically significant difference, between the clinical parameters examined at T0 and T1, for Group 1 and 2: BOP (p=<0.001), PPD (p=<0.001), CAL (p=<0.001). The analysis of the Groups 1 and 2, in relation to the three clinical parameters, at the time T1, shows that for the BOP and PPD there were statistically significant differences (BOP p<0.001), (PPD p=0.02). There was no statistically significant difference between the Groups 1 and 2 in relation to CAL at the time T1 (CAL p=0.11).
Conclusions. The subjects with CP, treated with SRP and probiotic, show some beneficial effect of Lactobacillus reuteri with significant reduction of BOP and PPD.

Purpose. The purpose of this study was to evaluate the effect of bone augmentation by periosteum extension using 3-dimensional memory nickel-titanium mesh sheets in rabbit nasal bone.
Materials and methods. Twenty four rabbits (aged 12-16 weeks; 2.5-3.0 kg) were used in this study. In the experimental group, the 3-dimensional memory nickel-titanium mesh sheet was inserted under the periosteal membrane and kept in place for 3 weeks using a screw. The screw was then removed and the mesh recovered its shape gradually. In the control group, the mesh was kept inserted under the periosteal membrane. Four animals were sacrificed in each period in both groups at 6, 9 and 11 weeks postoperative. The carcasses were prepared for immunological assessment and histological assessment. The bone area and expression of bone morphogenetic protein 2 (BMP-2) were evaluated.
Results. Bone ratio and bone area were significantly higher in the experimental group higher values than the control group after 9 and 11 weeks (P=0.0337, P=0.0027). Monoclonal anti-BMP-2 antibody stained cell number was significantly higher in the experimental group than the control group after 6 weeks (P=0.0001).
Conclusion. The results suggested that periosteum extension using a 3-dimensional shape memory nickel-titanium mesh sheet will likely induce new bone regeneration more than a titanium mesh sheet.

The current retrospective controlled trial aimed to compare the dentoskeletal effects of the Bite-Jumping (BJ) and the Twin-Block Appliance (TB) in the treatment of skeletal Class II malocclusion. The sample was screened for eligibility criteria including skeletal and dental Class II malocclusion; Cervical Vertebral Maturation at Stage 3 at treatment start, and Functional orthopedic treatment with either a TB or BJ appliances. Twenty-three patients treated with TB, and twenty-three treated with BJ were included. Cephalometric data were compared with a control group of 15 untreated subjects retrieved from the American Association of Orthodontists Foundation Craniofacial Growth Legacy Collection. Baseline characteristics were similar between groups. A significant increase for the AO-BO dimension, and a significant decrease in the overjet, were registered for both study groups respect to controls. TB was more effective than BJ in increasing the mandibular length (Co-Gn), in reducing the ANB angle and changing the SNB angle. The resulting differences between the two groups could be attributed to the different appliances. In conclusion, both appliances demonstrated a clinical efficacy in treating Class II. TB seems therefore better indicated, respect to BJ, in Class II cases with a predominant component of
mandibular hypoplasia.

Objectives. Adolescent patient treated for bilateral impaction of permanent maxillary canines with adjacent lateral incisors roots resorpted.
Methods. M.T., 13 years, male, shows a Class II molar relationship with the persistent of both upper deciduous canines and the unerupted successors. Analysis of CBCT confirms the impaction of maxillary canines and the root resorption of both maxillary lateral incisors. The treatment plan provided an orthodontic-surgical approach for adequate space management in dental arch, evaluation of eruption movements, choice of anchorage device, surgical exposure and application of Quad Helix Canine System and brackets.
Results. A functional occlusion with Class II molar relationship was obtained, the impacted maxillary canines were recovered into the arch preserving the lateral incisors. Good intercuspation was achieved and midlines were coincident.
Conclusion. 3D images are important to control the eruption movements of impacted canines, orthodontic mechanics and forces. In this clinical case, good esthetic and stable results were obtained. Resorpted lateral incisors were maintained as well as the periodontium.

Abstract

Purpose. The World Health Organization estimated edentulism rates ranging from 6 to 69% all over the world, and from 15% to 78% in Europe. In Italy, edentulism is more diffuse among women, especially from the age of 70. Since, women with an average age of 75 or above may reach rates of up to 52.2%, against the 47.6% of men. Non-rehabilitated edentulous people represent a scarce percentage in our country, only the 5% between over 70s. Total conventional removable prostheses remain the main treatment for edentulism, even though alternative techniques such as implant-prosthesis exist. Our study evaluated the patients’ masticatory efficiency and the quality of both superior and inferior total mobile removable prostheses implanted in those 12 individuals. Furthermore, the relationship between prosthesis quality, prosthesis age and masticatory strength and efficiency has been taken into consideration.
Materials and methods. Our study analysed total removable superior and inferior prosthetic rehabilitation in 12 completely edentulous patient cured by the Dental School’s prosthesis department of Bari University. Our analytic methods comprehended: state evaluation criteria to assess objective prosthesis quality; subjective questionnaire about masticatory ability; colour mixing test, a colorimetric test of the chewing gum with double colour to evaluate masticatory efficiency. We found a direct connection between prosthesis quality, prosthesis age and masticatory efficiency.
The subjective evaluation questionnaires gave a general idea about patient's masticatory ability, although biased
towards the adaptation level of each patient. The relation between prosthesis’ quality and its age-related usage has highlighted a decrease in total removable prostheses’ quality accompanied by its increasing age-related usage.
Results. From the colorimetric test, we can infer that the analysed masticatory efficiency is correlated with prosthesis quality and age. The data obtained about the prosthesis’ quality are based on subjective evaluation through a questionnaire, which is influenced by the adaptation of the patient’s alimentary habits over time; the questionnaire consistedin asking the patient about the difficulty level in chewing food of low, medium or hard consistency. Patients tend to substitute aliments they cannot chew/ingest with another aliment. Our study has emphasised a correlation in the relationship between the prosthesis’ quality and its age-related usage, showing a decrease in the total mobile prosthesis’ quality accompanied by its increased age-related usage. In particular, the quality is noticeably reduced after 10 years, which can be considered the average life of a prosthetic artefact if exposed to periodic checkups and maintenance.
Conclusions. Prosthesis quality needs to be evaluated over a wider range of cases. Hopefully in the near future, both quality evaluation criteria of total mobile prosthesis and the test to determine their masticatory efficiency will be effectively and broadly used in an objective manner, with the goal of improving prosthesis performances.

Objectives. We analysed the results of free-flap surgery in the head-and-neck area performed in a tertiary-care Italian hospital; we focus on the evolution of our approach toward bony reconstructions.
Methods. We retrospectively studied all patients who underwent free-flap reconstructive surgery in our institution from April 2010 to June 2018. Flap harvesting, disease aetiology, defect site, success and complication rates, demographic data, and comorbidities were analysed.
Results. A total of 134 free flaps was harvested in 127 patients. Fibular and radial forearm flaps were the most commonly used (45.5 and 26.1%, respectively). The overall free flap placement success rate was 96% and the complication rate was 16.4%.
Conclusion. Free tissue transfer has become a safe and reliable means of repairing soft tissue and bony defects of the head-and-neck region. Tailored surgery optimises outcomes and patient satisfaction.

Objectives. The aim of this pilot split-mouth controlled human study is to evaluate histologic and histomorphometric results of a highly purified xenogenic grafting material in maxillary sinus floor augmentation after six months of follow-up.
Methods. This pilot split-mouth study was conducted on 11 patients, 7 females and 4 males (mean age 53 +/- 7.9 years; range 41-68 years), who underwent maxillary sinus floor augmentation. The following biomaterials were used: Laddec: a highly purified bovine xenograft, that was the test material; and Bio-oss a natural bone mineral, that was the control material.
Six patients (4 females, 2 males) were treated with unilateral major maxillary sinus floor augmentation with Bio-oss, and five patients (3 females, 2 males) were subjected to bilateral major maxillary sinus floor augmentation, with Bio-oss in one side and Laddec in the other side. Consequently, the test group (Laddec) included 5 samples, while the control group (Biooss) included 11 samples.
Results. For the Laddec, the newly formed bone was 36% ± 2.3; the intertrabecular spaces were 34% ± 1.6, and the residual material was 30% ± 1.4. For the Bio-Oss, the newly formed bone was 38% ± 1.6; the intertrabecular spaces were 26% ± 1.6, whereas the residual material was 36% ± 3.1.
Conclusions. Both the xenoimplants obtained a good bone regeneration with a satisfying quantity of newly formed bone and reduced quantity of fibrous bone. The Laddec showed a better absorbability compared with Bio-Oss, whose residual percentage is greater for the same elapsed time.
