Abstract
BACKGROUND During the debonding phase every clinician has to take care of preserving the enamel structure and tooth temperature. The objective of this study was to analyze in vitro the increase of the pulp chamber temperature and the wearing of enamel surface, during adhesive removal after debonding. METHODS Sixty extracted human teeth were selected. An orthodontic bracket was bonded on each tooth and after bracket removal, intraoral scanner pictures were used to evaluate ARI for each tooth. Three different burs were tested: tungsten-carbide multiple blades, arkansas stone and ceramic bur. A mechanical arm controlled by a dedicated software was used to reproduce a repeatable act of composite removal. To analyze in vitro the pulp chamber temperature during the composite removal procedure, teeth were treated endodontically placing a thermocouple through the root canal from the apex. A software registered temperature changes in a continuous manner. The enamel surface of every tooth was tested after the removal of composite with an optical stereoscopic microscope. RESULTS An association existed between maximum internal pulp chamber temperature variation and irrigation (P<0.0001) and between maximum internal pulp chamber temperature variation and bur type (P=0.0133), with a significantly lower temperature increase produced by the arkansas bur. A significant difference among groups was detected for ESI and EDI assessment (P=0.002, P=0.010). CONCLUSIONS Considering the initial setup, temperature variation analysis showed more conservative results using the arkansas burs with irrigation. ESI and EDI indexes showed significant enamel surface damage using tungsten-carbide burs.

Abstract
AIM To compare the effects on permanent or deciduous anchorage dental units in patients treated with a digitally designed palatal expander. METHODS Inclusion criteria were the following: presence of maxillary transverse deficiency, no previous orthodontic treatment, no extractions, absence of agenesis, congenital pathologies and cranio-maxillofacial malformations. Twenty patients (11 males, 9 females, 11 ± 1.8 years) received a digitally designed and metal printed palatal expander anchored on first permanent molars and 1 activation per day for 30 days (Group 1). Twenty-one patients (12 males, 9 females, 8.6 ± 1.4 years) received a digitally designed and metal printed palatal expander anchored on second deciduous molars and 2 activations per day for 14 days (Group 2). Digital intraoral scans were taken before expansion and after device removal, and torque and the palatal transverse diameter were digitally measured. The FDI notation was used to indicate each tooth CONCLUSION: Less dental torque augmentation was produced in Group 2. RESULTS Significant intragroup differences over time were found in Group 1 considering the torque of teeth 1.6, 1.4, 1.3, 2.1, 2.4, 2.5, 2.6. Significant differences between groups were found regarding the longitudinal change in torque of teeth 1.5, 2.4 and 2.5. Significant intragroup differences over time were found in both groups considering all transverse diameter parameters. No significant differences were found between groups in the transverse diameter modifications over time. CONCLUSION Less dental torque augmentation was produced in Group 2.

Abstract
INTRODUCTION Maxillary expansion in patients at the end of their growth relies on the possibility to use miniscrew supported expanders to apply expansion forces directly to the midpalatal suture. Although miniscrews provide a stable anchorage unit, several studies have reported that they do not remain in exactly the same position during treatment. The aim of the present study was to analyze miniscrew position changes after the expansion using bone-borne appliances in late adolescent patients. METHODS Nineteen patients (13 females, 6 males), with a mean age of 17.81 (SD = 4.66), were treated with a Bone-Borne Expander Device. The appliance was designed with 4 miniscrews: 2 in the anterior palatal area, at the third rugae level; 2 in the posterior area. A CBCT and an intraoral scan were obtained before treatment (T0), and then, a second CBCT was obtained after the expansion (T1). Data on peri-suture bone thickness were collected at T0, then the CBCTs were superimposed, and changes between mini-screws position on T0 and T1 were evaluated, both by linear and angular displacements. RESULTS Significant longitudinal differences were found in the distance of the head and the tip of miniscrews measured at the occlusal plane, as well as angular changes. Correlations between displacement measurements and peri-suture bone thickness and height measurements were found as well. CONCLUSIONS While acting as bone anchor units, miniscrews do not remain in the same position during bone-borne expansion. The amount of displacement was related to peri-sutural total bone height and cortical thickness, especially in the anterior area of the naso-frontal maxillary complex.

Abstract
INTRODUCTION To compare the clinical outcomes of anterior single maxillary implants placed using conventional or guided implant surgery. METHODS In this retrospective clinical study 44 patients rehabilitated with a single anterior implant in the maxillary arch were included. Twenty-four implants were inserted applying a guided surgery approach (GS), and 20 applying a conventional freehand approach (CS). Outcome measures were: implant survival rate and complications; mean bone level (MBL) evaluated at surgery (T0), after 6 weeks (6 W), and after 1 year (1Y), 2 years (2Y), 3 years (3Y), 4 years (4Y), and 5 years (5Y); patients' satisfaction evaluated through a questionnaire filled out before surgery (BS) and at 1 week, 6 W, 2Y and 5Y; Pink esthetic score (PES) and white esthetic score (WES) evaluated at 1Y, 3Y and 5 Y. Significance of differences between groups were tested by Fisher's exact test, Mann-Whitney U test, and Wilcoxon's signed rank test. RESULTS During the 5-year follow-up there were no drop-outs and no implant failed. No significant differences between groups were found in MBL. A significant difference between groups was found in VAS scores regarding speech at 2 years, aesthetics at 6 weeks, confidence at 1 week and 6 weeks, satisfaction at T0 and at 1 W, pain/comfort at 1 W and at 6 W; all VAS scores resulted significantly improved compared to baseline. No significant differences in WES were found, while significant differences in PES scores between CS and GS groups were found at 3 and 5 years (p value = 0.023 and 0.004 respectively) with better outcomes for GS. A significant difference over time was found in PES between 5-year and one-year values. CONCLUSIONS Guided surgery and conventional surgery implants did not show any difference in MBL during the 5-year observation period. Guided surgical procedure guarantee optimal esthetic outcome and seems able to guarantee better soft tissue result over time, even though more long-term studies are necessary to confirm this data.

Abstract
INTRODUCTION The anterior area of the palate is widely used as an insertion site for orthodontic miniscrews. These temporary anchorage devices can be placed either directly or using an insertion guide, and various kinds of digital planning and guides are currently available. This study aimed to verify if the guided procedure can guarantee the correct position of the miniscrews on the patient compared with the digital project. METHODS Twenty-five consecutively treated patients were included in the study. Angular and linear displacements of the miniscrews were evaluated among 3 groups: the planned position, the model position, and the achieved position. RESULTS The median achieved angle between 2 digitally planned screws was 6.22° (interquartile range: 4.35°, 9.08°) and the difference between the angles in the planning and the achievement groups was significant (P <0.001). Lateral and vertical differences were also found among the 3 groups. CONCLUSIONS Results show that the examined workflow is clinically efficient. Differences between the digitally planned position of the orthodontic miniscrews, the control position, and the achieved position were detected both for angular and linear measurements but were not clinically significant.

Abstract
BACKGROUND Surface treatment of miniscrews was implemented to determine whether its application increased bone-to-surface contact and enhanced the interlock between the device and the surrounding bone. OBJECTIVES To compare the success rate of surface-treated and non-treated orthodontic miniscrews used as reinforcement of anchorage during treatment with the Herbst appliance. TRIAL DESIGN Split-mouth design with an allocation ratio of 1:1. METHODS Eligibility criteria to enrol patients were skeletal and dental class II patients with a retrusive chin, use of the Herbst appliance to correct malocclusion, need for skeletal anchorage using a miniscrew both in the left and right side of the mouth, absence of systemic diseases, absence of using drugs that alter bone metabolism, and good oral hygiene. Patients received self-drilling miniscrews without surface treatment and with surface treatment. Both types presented a 1.4 or 1.2 mm diameter. Miniscrews were inserted between the first molar and second premolars or between the two premolars. The force applied to the screws was an elastic chain from the head of the miniscrews to a direct button applied on the canines. The success rate of each type of miniscrew was considered the primary outcome, and the association of success with demographical, clinical, and geometrical characteristics was investigated. Differences were tested by the generalised linear mixed effects model for the split-mouth design. Differences with a P-value < 0.05 were selected as significant. RANDOMISATION A randomisation list was created for the mouth side assignment. BLINDING The study was single blinded with regard to the statistical analysis. RESULTS Thirty-nine miniscrews of the non-treated type and 39 miniscrews of the surface-treated type were inserted in 39 patients (23 female and 16 male, mean age: 15.55 ± 7.91) recruited between March 2018 and December 2020 with a split-mouth study design. The mean therapy duration was 9.3 months (SD = 1.31). No differences in failure rate were observed between miniscrew types. No serious harm was observed. CONCLUSIONS The success rate of surface-treated and non-treated miniscrews showed no significant differences. REGISTRATION This trial was not registered.

Abstract
ABSTRACT Introduction: Rowers are especially prone to oral health problems due to the massive consumption of supplements and isotonic drinks that lead eating disorders, due to the need for weight control, and to the development of teeth clenching caused by the constant activation of the chewing muscles during sports activity. Objective: To evaluate the oral health status of a group of Brazilian rowers and to identify the main risk factors influencing their oral health. Methods: One hundred and twenty rowers (84 men and 36 women) with an age of 24.16 ± 5.74 years participated in this study; an average height of 1.79 ± 0.09 cm and body mass of 75.02 ± 11.64 kg were detected by means of a questionnaire focused on the main factors that influence the deterioration in athletes’ oral health. Results: The dental results revealed a significant number of rowers with the oral breathing pattern (46.7%), malocclusion (65.8%), bruxism (33.3%) and noise and/or pain in the TMJ (temporomandibular joint) (20.8%). The use of supplements and isotonic drinks (48.3%) and the incidence of bleeding gums (30.83%) were also found. Conclusion: The results show the importance of making rowers aware of the relevance of oral health and the need for prevention systems, ideally including sports dentistry specialists within the sports medicine departments of rowing clubs. Level of evidence II; Retrospective study.

Abstract
BACKGROUND Direct and 3D-assisted methods are an available alternative when inserting temporary anchorage devices (TADs) in the anterior palate for orthodontic anchorage. This study aimed to evaluate the differences between a planned insertion versus a direct method on digital models. SETTINGS AND SAMPLE POPULATION Seventy TADs were inserted by the direct insertion method in 35 patients who needed palatal TADs for orthodontic anchorage. For each patient, placement was independently planned by the superimposition of lateral cephalograms and corresponding plaster models. After mini-implant placement, impressions were taken with scanbodies. For the measurement of both linear and angle deviations, virtual planning models and postoperative oral scans were compared using 3D software for automatic surface registration and calculations. RESULTS Comparing TADs positioned by the direct method and the digitally planned method, a mean linear distance was found of 2.54 ± 1.51 mm in the occlusal view and 2.41 ± 1.33 mm in the sagittal view. No significant difference has been found between TADs positioned in the right and left palatal sides. A mean distance of 7.65 ± 2.16 mm was found between the tip of the digitally planned TAD and the central incisors root apex. CONCLUSIONS Both direct and 3D-assisted TAD insertion methods are safe and accurate in the anterior palate. However, the use of insertion guides facilitates TAD insertion, allowing less-experienced clinicians to use palatal implants.

Abstract
INTRODUCTION Rapid palatal expansion is a common therapy during orthodontic treatment and could be a preliminary step for correcting different malocclusions; furthermore, this treatment could be necessary at any age. Different anchorage approaches have been proposed to obtain an effective skeletal result, although every device produces both dental and skeletal effects. This study aimed to compare the dentoskeletal effects of a bone-borne palatal expander considering 2 groups of patients of different ages. METHODS Twenty-four patients consecutively treated were included in the study; patients were divided into 2 groups according to their age: group 1 with age ≤16 years and group 2 patients >16 years. All patients had a preexpansion cone-beam computed tomography scan; a second scan was required at the end of activations. All patients received a bone-borne appliance anchored on 4 miniscrews. RESULTS Significant intragroup differences were found for maxillary width and dental diameters. No significant differences were found between groups with regard to longitudinal changes, except for the maxillary right plane. CONCLUSIONS The use of bone-borne maxillary expansion was effective in generating palatal widening both in growing and young adult patients. No significant skeletal or dental differences were found between groups.

Abstract
BACKGROUND The aim of the present study was to compare two different anchorage systems efficiency to disinclude impacted maxillary canines using as evaluation tool superimposed Cone Beam Computed Tomography (CBCTs). METHODS The study has been conducted with two parallel groups with an allocation ratio of 1:1. Group test received treatment using as anchorage a miniscrew, control group was treated using an anchorage unit a trans palatal arch (TPA). Both groups received a calibrated traction force of 50 g. CBCT before treatment and 3 months after traction were superimposed and canine tip and root movement were evaluated in mm/month ratio. RESULTS No differences were observed between groups for apex displacement, tip displacement and observation timespan. Twenty-two patients (12 female, 10 male, mean age:13.4 years) undergoing orthodontic treatment for impacted maxillary canines were recruited for this study. No differences were observed between groups for apex displacement, tip displacement and observation timespan. CONCLUSIONS The present pilot study provided no evidence that indirect anchorage on miniscrews could make canine disimpaction faster than anchorage on a TPA. An apex root movement of 0.4-0.8 mm per month was found, while average canine tip movement ranged between 1.08 mm and 1.96 mm per month. No miniscrews failures were observed. TRIAL REGISTRATION The study reports the preliminary results of the randomized clinical trial registered at www.register.clinicaltrials.gov (registration number: NCT01717417 ).

Eligibility criteria were needs of fixed orthodontic treatment, no systemic disease and absence of using drugs altering bone metabolism. MATERIAL AND METHODS Patients received miniscrews, 2.0 mm diameter and 10 mm length. All miniscrews underwent inter-radicular placement, and they were placed in the maxilla or in the mandible, palatally or buccally. No pre-drilling was performed. Miniscrews were loaded immediately after the insertion and were used for distalization, intrusion, extrusion, mesialization or indirect anchorage. Patients were randomly divided into three groups. For each patient, Maximum Insertion Torque (MIT) was evaluated at baseline. MIT was measured again after 2 weeks and after 4 weeks by tightening the screw a quarter of turn in Groups 1 and 2, respectively. At the end of the treatment, maximal removal torque was evaluated in Group 3. Torque variation with respect to insertion time was considered as the primary outcome. Baseline and longitudinal differences were tested using the linear mixed-effects (LME) model. RESULTS Forty seven patients and 74 miniscrews were followed up. An association existed between maximum insertion torque and the observation time. A torque decrease of 26.9% and 30% after 2 weeks was observed for mandibular and maxillary miniscrews, respectively. After 1 month, torque values were similar to the baseline records. The overall success rate was 79.7%. No serious harm was observed. CONCLUSIONS Maximum insertion torque undergoes a loss during the first 2 weeks, and its values may depend on the insertion site and the anchorage purpose. Removal torque value is almost the same as the initial torque after 1 month.

Abstract
BACKGROUND Class II is one of the most common malocclusions. The prevailing aspect in Class II patients is a mandibular deficiency. Various removable and fixed functional therapies are used in order to enhance the mandibular growth or position. The aim of this prospectively controlled study was to evaluate long-term dentoskeletal changes obtained by a functional appliance for Class II. METHODS Prospective controlled study, based on a sample size calculation. 26 Class II Division 1 patients (11.8±1.5 years) were consecutively treated with the propulseur universal light (PUL) appliance and a multi bracket appliance (PG), they were compared to a sample of 26 Class II untreated patients (11.5±0.8 years) (CG). Lateral cephalograms were taken before and after the PUL therapy, and after multibracket treatment. Interaction analysis was carried out to test whether the PUL parameters in treatment groups were different according to the acquisition times, using the Linear Mixed-Effects Model. RESULTS Significant ANB, Overjet and WITS differences existed in treatment groups according to the time. In particular, comparing to T1 vs. T0, the relative difference (RD) means in the control group were -0.34, -0.31 and 0.17 for ANB, Overjet and WITS, respectively. The corresponding RD means in the treated group PG were -1.58, -4.27 and -2.38. Comparing to T2 vs. T0, the RD means in the control group were -0.36, -0.51 and 0.63 for ANB, Overjet and WITS, respectively. While the corresponding RD means in the treated group were -2.08, -5.12 and -2.50. CONCLUSIONS The PUL appliance successfully corrected class II malocclusion. The long term correction was mainly due to dentoalveolar effects: therapy success was 91% for overjet correction and 76% for ANB correction. During the post functional appliance period, overjet was stable in 77% of the treated subjects, and ANB in 74% of the treated subjects.

Abstract
BACKGROUND An alternative approach to surgery for treating class II adult borderline patients is the non-extraction and multiloop edgewise archwire (MEAW) technique. The aim of the present study is to compare dentoskeletal effects of the orthognathic surgery with the MEAW technique. METHODS Thirteen adults (ten women, three men; mean age, 27.8 years) were consecutively treated using the MEAW approach. The control group was made of 13 adults (nine women, four men; mean age, 26.2 years) treated by orthognathic surgery and the multibracket appliance before and after surgery. Lateral headfilms before and after all the treatments were traced for linear and angular measurements, and data were blindly analyzed. ANOVA was conducted to compare any difference over time between the two treatments. Differences over time for each variable, separately for surgery and MEAW, were assessed by Wilcoxon test. RESULTS No significant differences between the two groups were detected at baseline. Both treatments were effective in correcting dental discrepancies. A significant difference over time between the two treatments was found in several cephalometric measurements. CONCLUSIONS Considering the limits of the present sample the following conclusion emerged: in the MEAW group, the malocclusion correction was predominantly dentoalveolar, and a significant profile change was observed. Significant skeletal and occlusal plane changes were obtained with the orthognathic surgery approach.

Abstract
Little is known about the course of the plasma concentration and the bioavailability of non-steroidal anti-inflammatory drugs (NSAIDs) contained in dermal patches. We compared an etofenamate prototype patch (patent EP 1833471) and a commercially available diclofenac epolamine patch regarding the bioavailability of the active ingredients relative to respective i.m. applications and regarding their plasma concentration-time course. Twenty-four healthy human volunteers were treated using a parallel group design (n = 12 per group) with a single dermal patch (removed after 12 hr) followed (after a latency of 48 hr) by eight consecutive dermal patches every 12 hr to reach steady-state conditions. The patches were generally well tolerated, but one volunteer treated with etofenamate developed an allergic contact dermatitis. After the first patch, Cmax was 0.81 ± 0.11 (mean ± S.E.M.) ng/mL (reached 12 hr after patch removal) for diclofenac and 31.3 ± 3.8 ng/mL for flufenamic acid (reached at patch removal), the main metabolite of etofenamate. Etofenamate was not detectable. After repetitive dosing, trough plasma concentrations after the eighth dose were 1.72 ± 0.32 ng/mL for diclofenac and 48.7 ± 6.6 ng/mL for flufenamic acid. Bioavailabilities (single dose) relative to i.m. applications were 0.22 ± 0.04% for diclofenac and 1.15 ± 0.06% for flufenamic acid. In conclusion, the relative bioavailability (compared to the respective i.m. application) of both drugs is low. The maximal plasma concentrations after topical administration of these drugs are well below the IC50 values for COX-1 and COX-2, explaining the absence of dose-dependent toxicities.

Abstract
BACKGROUND The aim of this study was to analyze the psychological aspects of patients during their orthodontic treatment, evaluating their expectations during treatment comparing Greek patients to Italian patients. METHODS This cross sectional descriptive study involved a sample of 228 patients (113 Italians -115 Greeks) undergoing fixed or removable orthodontic treatment. A questionnaire comprising of six questions was used and patients scored each question on a 0-10 Scale. Participants completed a validated questionnaire measure of orthodontic expectations that was tested for reliability. Descriptive analysis of the responses was undertaken, and comparisons between boys and girls, as well as between Greek and Italian patients, was made. The expectation score was calculated by summarizing the 6 items (A1 to A6). Reliability Analysis was performed using the Item-test, Item-rest correlation and the Cronbach's α. Items with a Cronbach's α coefficients greater than 0.7 are considered acceptable. To investigate the effect of the City and Gender on the expectation score, an univariate analysis was carried out by the Wilcoxon Rank Sum Test. Differences, with a P value less than 0.05, were selected as significant. RESULTS Overall expectation Cronbach's α coefficient (internal consistency) was 0.73 (95% CI: 0.64-0.81). The mean of expectation items was 7.8 (SD=1.8). A significant slight correlation was found between motivation (item A1) and main reason of treatment (item A3) (r=0.17; P=0.0122). Moreover, there was a significant moderate correlation between compliance (item A4) and expectation (item A6) (r=0. 58; P<0.0001). CONCLUSIONS Male showed a significant higher overall score compared to female sample, as well as Greek patients compared to Italians.

Abstract
To evaluate torque loss a week after insertion, both in an in vivo and an in vitro experimental setup were designed. In the in vivo setup a total of 29 miniscrews were placed in 20 patients who underwent orthodontic treatment. Maximum insertion torque (MIT) was evaluated at insertion time (T1). A week later, insertion torque was measured again by applying a quarter turn (T2); no load was applied on the screw during the first week. In the in vitro setup a total of 20 miniscrews were placed in pig rib bone samples. MIT was evaluated at insertion time (T1). Bone samples were kept in saline solution and controlled environment for a week during which the solution was refreshed every day. Afterwards, torque was measured again by applying a quarter turn (T2). The comparison of MIT over time was done calculating the percentage difference of the torque values between pre- and post-treatment and using the parametric two independent samples t-test or the non-parametric Mann–Whitney test. After a week unloaded miniscrews showed a mean loss of rotational torque of 36.3% and 40.9% in in vitro and in in vivo conditions, respectively. No statistical differences were found between the two different setups. Torque loss was observed after the first week in both study models; in vitro experimental setup provided a reliable study model for studying torque variation during the first week after insertion.

Abstract
INTRODUCTION The aim of this randomized clinical trial was to compare torque recordings at insertion time and 1 week post-placement between immediately loaded orthodontic miniscrews and an unloaded control group. TRIAL DESIGN This RCT was designed as parallel with an allocation ratio of 1:1. METHODS Eligibility criteria to enroll patients were: needs of fixed orthodontic treatment, no systemic disease, absence of using drugs altering bone metabolism. All patients were consecutively treated in a private practice and the miniscrews were placed by the same author. Patients received ORTHOImplant (3M Unitek) miniscrews and they were blindly divided in two groups: group 1 screws were unloaded between T0 and T1, group 2 received immediately loaded screws with NiTi coil. For each patient, maximum insertion torque (MIT) was evaluated at T0. After 1 week, without loading, the screw torque was measured again (T1) and at the end of the treatment maximal removal torque was evaluated (T2). Torque variation in the first week was considered as the primary outcome. RANDOMIZATION A randomization list was created for the group assignment, with an allocation ratio of 1:1. BLINDING The study was single blinded in regard of the statistical analysis. RESULTS Patients enrolled in the clinical trial were 51 for a total of 81 miniscrews. The recruitment started in November 2012 and the observation period ended in August 2014. Twenty-six and twenty-five patients were analysed in group 1 and 2, respectively. The MIT mean in each placement time was 18.25 Ncm (SD = 3.00), 11.41 Ncm (SD = 3.51) and 10.52 Ncm (SD = 5.14) at T0, T1, and T2 time, respectively. In group 1, the torque decrease between T1 and T0 was statistically higher compared to group 2 (P value = 0.003). Statistically significant effects of the placement times on MIT were found (P value <0.0001). No serious harm was observed. LIMITATIONS This study was performed using only direct force on the miniscrew and not using the miniscrew as an indirect anchorage. It was not possible to obtain quantitative data on bone quality or root proximity to miniscrews. CONCLUSIONS A significant stability loss was observed in the first week in both groups; Group 1 showed a statistically higher torque loss in the first week when compared to the immediately loaded group. There were statistically significant effects of the measurement times on MIT and of the miniscrew location on MIT. The overall failure rate was 7.4%. TRIAL REGISTRATION This trial was not registered. PROTOCOL The protocol was not published before trial commencement.

Abstract
INTRODUCTION The purpose of this study was to evaluate the correlations between bone characteristics, orthodontic miniscrew designs, and primary stability. METHODS Four different miniscrews were placed in pig ribs. The miniscrews were first scanned with a scanning electron microscope to obtain measurable images of their threads. Subsequently, the maximum insertion torque of the screws and the maximum load value in the pullout force tests were measured; furthermore, bone specimen characteristics were analyzed by using cone-beam computed tomography. For each bone sample, the insertion site cortical thickness as well as both cortical and marrow bone density were evaluated. The nonparametric Kendall rank correlation (tau) was used to evaluate the strength of the associations among the characteristics measured. The nonparametric Kruskall-Wallis test was used to evaluate the differences among the groups, and post-hoc comparisons were assessed by using the Nemenyi-Damico-Wolfe-Dunn test. RESULTS A significant dependence was found between pitch and maximum insertion torque (tau, -0.49). Positive correlations were also found between pullout force and maximum insertion torque (tau, 0.64), cortical thickness (tau, 0.36), and marrow bone density (tau, 0.35). CONCLUSIONS In this in-vitro experimental study, strong correlations were observed among miniscrew geometry, bone characteristics, and primary stability.

Abstract
The thread shape factor (TSF) to evaluate the relationships between geometrical characteristics and mechanical properties of the temporary anchorage devices (TADs) has recently been introduced. This in vitro experimental study evaluated in 30 different tests with three TADs: ORTHOImplant (1.8 mm diameter and 10 mm length; 3M Unitek), Tomas (1.6 mm diameter and 10 mm length; Dentaurum), and Orthoeasy (1.7 mm diameter and 10 mm length; Forestadent). Scanning electron microscopy images were acquired for each TAD to measure the TSF; afterwards, the maximum insertion torque (MIT) was evaluated and thereafter pull-out tests on two differently designed organic bone analogs were carried out using a testing machine with a crosshead speed of 2 mm/minute being applied. One-way analysis of variance with group as factor was performed. Post hoc multiple comparisons Bonferroni test was used. Rank-transformed data were used when asymmetry of data was shown. To assess correlation between characteristics, load, and MIT, Spearman's rank correlation coefficient was used. A P-value of 0.05 was considered statistically significant. Significant direct correlations were found between TSF and depth and both load and MIT. Particularly, a correlation of 0.90 (P < 0.001) was found between depth and MIT for 2.2 mm cortical thickness. The authors conclude that MIT and maximum load values of pull-out test are statistically related to depth of the thread of the screw and to TSF.

Abstract
BACKGROUND Data on the burden of rotavirus gastroenteritis in Europe are needed to help understand the potential impact of introducing new rotavirus vaccines. MATERIALS AND METHODS As part of prospective observational study (Rotavirus gastroenteritis Epidemiology and Viral types in Europe Accounting for Losses in Public Health and Society Study, REVEAL) conducted in 2004--2005 in seven European countries, we studied, the characteristics of acute gastroenteritis and rotavirus gastroenteritis in children less than 5 years in primary care, emergency room and hospital settings (Padova, Italy). RESULTS A total of 757 children with acute gastroenteritis were included and enzyme-linked immunoabsorbent assay (ELISA) results were available for 725 cases. The overall estimated annual incidence for rotavirus gastroenteritis was 4.7%. Overall, rotavirus gastroenteritis was estimated to account for 43.6% of acute gastroenteritis cases. Among children with acute gastroenteritis (AGE) aged 6-23 months, 61.2% were rotavirus positive. Rotavirus gastroenteritis (RVGE) was responsible for 68.8% of hospitalizations, 61% of emergency consultations, and 33% of primary care consultations. The most prevalent serotype was G9 (84.4%) followed by G1 (11.8%). The relative risk for rotavirus gastroenteritis of being referred to hospital after an initial consultation in primary care was 3.37 (95% CI: 1.77-6.43) and 3.38 (95% CI: 2.28-5.01) for emergency room referral. Children with rotavirus gastroenteritis generally had more severe disease than children with rotavirus-negative gastroenteritis. CONCLUSION Rotavirus accounts for a significant proportion of acute gastroenteritis cases in children less than 5 years in Italy, many of whom require frequent primary care consultations, or care in emergency room or hospital settings.

Abstract
Prosopis alba (algarrobo) is an important indigenous specie, which fruits are used as food and feed since ancient times. Cookies containing algarrobo pulp (AP) with increased iron and calcium availabilities were formulated and sensory evaluated. AP is preferred as food ingredient because of its high sugar content and pleasant flavour. Formulated cookies mean proximal composition was 8.9 g/100 g protein, 7.2 g/100 g dietary fiber, 25 g/100 g total sugar, and 18.5 g/100 g crude fat with iron and calcium contents 30 ppm and 340 ppm, respectively. Ascorbic (AA) and citric (CA) acids at different mM acid: mM Fe were added in order to increase mineral availabilities being evaluated by an in vitro method. Those ratios were 5:1 and 10:1 for AA:Fe whereas for CA:Fe were 50:1 and 100:1 and combinations of them. After chosen the best AA:Fe and CA:Fe ratios (5:1 and 50:1, respectively), sensory evaluation with trained sensory panel and a consumer acceptability test with one hundred and seventy untrained judges were carried out. Acceptability test showed that 77.65% of the people (< 25 years old 41.76%, 25-50 years old 20.00% and > 50 years old 15.89%) tasting final formulated cookies indicated that they "like very much" or "moderately like" and there were not consumers rejecting them.

Abstract
BACKGROUND AND AIMS Despite the progress made in understanding the immunological aspects of the pathogenesis of coeliac disease (CD), the early steps that allow gliadin to cross the intestinal barrier are still largely unknown. The aim of this study was to establish whether gliadin activates a zonulin dependent enterocyte intracellular signalling pathway(s) leading to increased intestinal permeability. METHODS The effect of gliadin on the enterocyte actin cytoskeleton was studied on rat intestinal epithelial (IEC-6) cell cultures by fluorescence microscopy and spectrofluorimetry. Zonulin concentration was measured on cell culture supernatants by enzyme linked immunosorbent assay. Transepithelial intestinal resistance (Rt) was measured on ex vivo intestinal tissues mounted in Ussing chambers. RESULTS Incubation of cells with gliadin led to a reversible protein kinase C (PKC) mediated actin polymerisation temporarily coincident with zonulin release. A significant reduction in Rt was observed after gliadin addition on rabbit intestinal mucosa mounted in Ussing chambers. Pretreatment with the zonulin inhibitor FZI/0 abolished the gliadin induced actin polymerisation and Rt reduction but not zonulin release. CONCLUSIONS Gliadin induces zonulin release in intestinal epithelial cells in vitro. Activation of the zonulin pathway by PKC mediated cytoskeleton reorganisation and tight junction opening leads to a rapid increase in intestinal permeability.

Abstract
Celiac disease (CD) or gluten-sensitive enteropathy is an autoimmune disorder triggered by gluten ingestion in genetically predisposed subjects. The presence of gluten in these patients leads to a self-perpetuating mucosal damage, while the elimination of gluten results in a full mucosal recovery. The prevalence of CD in the general population is between 0.3% and 1%. The clinical manifestation of CD is variable; in addition to the classical gastrointestinal form a variety of other clinical manifestation of the disease have been described, including atypical and asymptomatic form. The diagnosis of CD is still based on the small intestinal biopsy findings, but can be suspected using serological testing, e.g. the antigliadin antibody (AGA), the antiendomysial antibody (EMA) and the anti-tissue transglutaminase antibody (tTG). The keystone treatment of CD patients is a life-long gluten-free diet.

Abstract
The aim of the present study was to clarify the mechanisms by which a sucrose-rich diet (SRD) produces an increase in the pancreatic beta-cell mass in the rat. Normal Wistar rats were fed for 30 weeks either an SRD (SRD rats; 63% wt/wt), or the same diet but with starch instead of sucrose in the same proportion (CD rats). We studied body weight, serum glucose and triacylglycerol levels, endocrine tissue and beta-cell mass, beta-cell replication rate (proliferating cell nuclear antigen; PCNA), islet neogenesis (cytokeratin immunostaining) and beta-cell apoptosis (propidium iodide). Body weight (g) recorded in the SRD rats was significantly (P<0.05) larger than that of the CD group (556.0+/-8.3 vs 470.0+/-13.1). Both serum glucose and triacylglycerol levels (mmol/l) were also significantly higher (P<0.05) in SRD than in CD rats (serum glucose, 8.11+/-0.14 vs 6.62+/-0.17; triacylglycerol, 1.57+/-0.18 vs 0.47+/-0.04). The number of pancreatic islets per unit area increased significantly (P<0.05) in SRD rats (3.29+/-0.1 vs 2.01+/-0.2). A significant increment (2.6 times) in the mass of endocrine tissue was detected in SRD animals, mainly due to an increase in the beta-cell mass (P=0.0025). The islet cell replication rate, measured as the percentage of PCNA-labelled beta cells increased 6.8 times in SRD rats (P<0.03). The number of apoptotic cells in the endocrine pancreas decreased significantly (three times) in the SRD animals (P=0.03). The cytokeratin-positive area did not show significant differences between CD and SRD rats. The increase of beta-cell mass induced by SRD was accomplished by an enhanced replication of beta cells together with a decrease in the rate of beta-cell apoptosis, without any evident participation of islet neogenesis. This pancreatic reaction was unable to maintain serum glucose levels of these rats at the level measured in CD animals.

Abstract
BACKGROUND Coronary artery reoperation represents about 20% of coronary artery operations. In this study we compared mortality and morbidity of first intervention and redo operation. METHODS EXPERIMENTAL DESIGN a retrospective study. SETTINGS patients who underwent coronary artery reoperations in a University Cardiac Surgery Division in 1991-1994. PATIENTS our clinical survey was composed of two groups: group A included 44 consecutive patients (mean age 60+/-7 years, males/females=41/3) who underwent a coronary artery reoperation in the years 1991-1994 at the University Cardiac Surgery Division of Turin; group B included 344 patients (mean age 58+/-8 years, males/females=289/55) randomly selected among those who underwent a first coronary operation in the above indicated period of time and centre. All patients had angina pectoris refractory to maximal medical therapy. INTERVENTIONS all patients underwent a coronary artery operation in extracorporeal circulation (ECC), under mild hypothermia (30-32 degrees C), during a single aortic clamp period, with antegrade cold crystalloid cardioplegia (St. Thomas). MEASURES comparison of clinical preoperative features, risk factors and postoperative mortality and morbidity between the two groups. RESULTS In reoperated patients we observed a greater mean akinesis score (p<0.001) and severe left ventricular dysfunction presence (p=0.014). Reoperation mortality was 11.4% against first operation mortality of 3.2% (p=0.03). Female gender (p=0.03), intra-aortic balloon counterpulsation need (p=0.002), adrenaline use (p=0.004) and low cardiac output syndrome (p=0.007) were all perioperative risk factors in group A. CONCLUSIONS Coronary artery reoperation involves a higher mortality and morbidity compared to the first operation, especially related to the reduced left ventricular function which characterises the population that undergoes reoperation.

Abstract
Transesophageal echocardiogram is the procedure of choice in the evaluation of masses located in the cardiac chambers. In this paper three cases of atrial thrombosis are presented: a) a free floating ball thrombus in the left atrium in a patient with moderate mitral stenosis; b) three thrombotic masses adherent to a central venous catheter; c) three thrombotic masses attached to Chiari s network in a patient operated for an ostium secundum atrial septal defect one year before. In all cases transesophageal echocardiogram has played a key role in the diagnosis. Medical therapy has been inadequate and so surgical removal has been performed. Unsuccessful medical therapy, a new episode of thrombosis, intracardiac permanent catheter infections and high risk of systemic and pulmonary embolism are indications for thrombectomy.

Abstract
Colchicine was introduced in 1987 for the treatment of recurrent pericarditis. Up to the present, papers have been published on a total of 117 patients treated with colchicine after the failure of treatment with FANS, corticosteroids and repeated pericardiocentesis. Here two cases of chronic pericardial effusion, one secondary to pericardiotomy, the second idiopathic, are reported. Both were recalcitrant to conventional therapy. Both patients were treated with 2 mg/die colchicine for 1 month followed by 1 mg/die for a further 5 months, without recurrence of the effusion after follow-up of 12 and 24 months respectively. No side-effects were observed. Colchicine is an anti-inflammatory drug which, by inhibiting various leukocyte functions, depresses the action of the leukocytes and of the fibroblasts at the site of the inflammation. We conclude that colchicine is effective in post-pericardiotomic and idiopathic chronic pericardial effusion as already reported in cases of recurrent pericarditis. Given the lack of side-effects, it could be considered as a drug of choice alternatively to FANS and corticosteroids.

Abstract
Colon cancer is the second leading cause of death for cancer disease, after lung cancer, with nearly 18,000 deaths per year in Italy. In spite of the progress that have taken place over the past 30 years, little improvement has been gained in this dismal outcome, and the 5-year survival remains around 50%. Over one half of the patients will suffer from recurrence after a potentially curative resection. A major challenge lies in better detection of recurrences in order to diagnose those patients still amenable to curative resection. Locoregional recurrence is of particular interest and its frequency, diagnostic limitations and surgical treatment are herein discussed.

Abstract
The aim of the present investigation was to study normal rats fed a sucrose-rich diet (SRD) for a prolonged period (up to 30 weeks) (1) to obtain additional data on the hormonal and metabolic patterns induced by this treatment and (2) to provide information on changes taking place in the pancreatic islet cell populations. We found that long-term feeding with a SRD resulted in a steady state of hypertriglyceridemia and hyperglycemia in which insulin levels remained unchanged and unable to compensate for the increased demands of the developing metabolic changes. The endocrine pancreas showed a significant increase of both islet number and B-cell area, as well as changes in the profile of islet cell distribution. However, these changes were not accompanied by an increase in the pancreatic content of immunoreactive insulin (IRI). It may therefore be postulated that the newly emerged B-cell mass has some sort of derangement with the increased insulin demand resulting from insulin resistance induced by the long-term SRD feeding. Thus, feeding a SRD to normal rats may prove to be an attractive animal model for studying the role of environmental nutritional factors in the unsettled issue of the relationship between insulin resistance and relative insulin deficiency. The model might provide key information for understanding the pathophysiology of human diseases such as type II diabetes, dyslipidemia, and a number of entities included in so-called syndrome X.

Abstract
BACKGROUND To determine whether administration of erythromycin (E) could facilitate passage of a nasoenteric feeding tube into the duodenum for postpyloric feedings, this randomized, double-blind, placebo-controlled trial was performed. METHODS Fifty-seven patients were accrued from the surgical intensive care units (ICUs) of a tertiary-care university hospital. Patients enrolled were categorized as to the presence or absence of diabetes mellitus (DM). Those patients without DM were then subdivided into those with normal or depressed mental status. The three groups, normal (NMS), depressed mental status (DMS), or diabetes mellitus (DM), were then randomized independently to receive either E or placebo (P), followed by blind placement of a feeding tube. Tube placement was verified by an abdominal radiograph. RESULTS Overall, the rate of postpyloric placement was 61% (19/31) in the E group, significantly better than 35% (9/26) in the P group (p < .05). In patients with NMS, the success rate with E was improved (64%, 9/14) compared with that with P (9%, 1/11) (p < .0005). In the DMS group, there was a 50% success rate (6/12) with E versus 63% (5/8) with P (not significant [NS]). In the DM group, 80% (4/5) of the patients had placement of the tube in the duodenum with E and 43% (3/7) with P (NS). CONCLUSIONS These data suggest that, overall, E is effective in facilitating placement of a nasoenteric feeding tube into the duodenum in ICU patients. It is clearly beneficial in those patients with normal mental status and may be useful in patients with diabetes mellitus.

Abstract
Patients with esophageal atresia (EA) or choanal atresia (CA) manifest similar clinical and pathophysiological features. To determine the significance of this observation, the clinical records of 80 patients with EA and 57 with CA were reviewed. This survey showed that similarities between the two conditions included inspiratory and expiratory dyspnea, episodes of reflex apnea and/or bradycardia, oropharyngeal dysphagia, vomiting, convulsions, hyperhydrosis, hyperthermia, sialorrhea, and sudden death. After the second year of life most symptoms disappeared spontaneously. In both conditions, respiratory effort resulted in partial or complete obstruction affecting both the inspiratory and expiratory phases of the respiratory cycle. Support for this finding was obtained by studying the breathing pattern of 3 patients with EA and 3 with CA, before and during postural respiratory loading. The data suggest that patients with EA are similar to those with CA, having upper airway instability that may result in obstructive hypopnea or apnea associated with expiratory grunting. It is possible that this upper airway instability is a manifestation of more general maturational dysautonomia previously not recognised in patients with EA.
