Background: Chronic periodontitis affects 47% of adult population over the age of 30. The first phase of periodontal treatment is always represented by scaling and root planning (SRP), that is a causal, non-surgical therapy that recognizes as primary aims the control of bacterial infection and the reduction of periodontal plaque-associated inflammation. Yet, another innovative causal therapy is represented by the irradiation of periodontal pockets with laser.
Aim: To evaluate the effect of a 940-nm diode laser as an adjunct to SRP in patients affected by periodontitis.
Materials and methods: Sixty-eight adult patients with moderate-to-severe periodontitis were sequentially enrolled and undergone to periodontal examination (V1) in order to detect gingival index (GI), plaque index (PI) and probing depth (PD). The patients were randomly divided into two groups: the first (n=34) received SRP treatment alone, the control group (n=34) received SRP and 940-nm diode laser therapy.
Results: Data were analyzed by Student's t-test, with two tails; for all clinical parameters, both groups reported statistically significant differences compared to basal values (p<0.0001). Both procedures were effective in improving GI, PI and PD, but the use of diode laser was associated with more evident results.
Conclusions: Considered the better clinical outcomes, diode laser can be routinely associated with SRP in the treatment of periodontal pockets of patients with moderate-to-severe periodontitis.

AIM To evaluate the impact of smoking and previous periodontal disease on peri-implant microbiota and health in medium to long-term maintained patients. METHODS A retrospective evaluation of partial edentulous patients restored with dental implants and enrolled in a regular supportive therapy was performed. Inclusion criteria were: medium to long-term periodontal and implant maintenance (at least 5 years), a minimum of 2 implants placed in each patient, absence of systemic diseases that may affect osseointegration. 30 implants in 15 patients were included in the study. Subjects were divided in smokers or non-smokers and between patients previously affected by periodontal disease and periodontally healthy. Peri-implant and periodontal parameters were assessed (PD,BoP, mPI). Microbiological samples were collected around implant and an adjacent tooth. Real- Time Polymerase Chain Reaction (RT-PCR) analysis was performed. RESULTS In all the three groups no differences in bacterial counts between dental and implant sites were observed. Non smoker, healthy patients: healthy clinical parameters, significant counts of spirochetes in isolated patients. Non smokers with previous periodontal disease: occasional positive BoP values, significant high counts of pathogenic bacteria. Smokers with previous periodontal disease: clinical signs of inflammation including deep pockets and slight bone resorption, significant counts of pathogenic bacteria. CONCLUSIONS Over a follow-up of 5 to 7 years, it is possible to state that the absence of smoking habit and previous periodontal disease positively influences the peri-implant microbiological and clinical conditions in partial edentulous patients restored with dental implants and enrolled in a strict regular supportive therapy.

AIM The aim of this research was to assess peri-implant bone remodeling of post-extractive implants over 2 years. MATERIAL AND METHODS 30 patients meeting pre-established inclusion criteria were enrolled for the study. One implant for each patient was inserted in the post-extraction sockets according to a defined surgical protocol (atramautic extraction, curettage of extraction socket, implant insertion, grafting with collagenated cortico-cancellous porcine bone, and a trimmed collagen membrane to completely cover the socket, suture). A temporary adhesive bridge, with an adequate profile, was bonded to the adjacent teeth. X-ray evaluation with a standardized stent was carried out at different times. Measurements were obtained from the implant edge to the bone peak. The values obtained at time 0 and at 2 years were compared by t-student test. RESULT Our results showed that after one year 73% of patient had 0 mm of bone reabsorption, 20% of patient had 0 mm ≤ x ≤ 0.5mm, 7% of patient had 0.5 mm ≤ x ≤ 2 mm of bone reabsorption. After two years 62% of patient had 0 mm of bone reabsorption, 24% had 0 mm ≤ x ≤ 0.5mm, 14% had 0.5 mm ≤ x ≤ 2 mm. CONCLUSIONS The results showed no significant differences in bone reabsorption in most patients over 2 years.

Aim: To compare the effect of brushing motion on torsional and cyclic fatigue resistance of TF Adaptive instruments after clinical use.
Methods: 20 packs of TFA small sequence (SybronEndo, Orange, CA, USA) were used for this study and divided into two groups. Each instrument prepared one resin tooth, consisting in 4 canals with a complex anatomy. In group A, no brushing motion was performed. In group B, after the green instrument reached the working length, brushing motion with circumferential filing was performed for 15 seconds in each canal (overall 1 minute). All the instruments were then subjected to cyclic fatigue test and mean values and standard deviation for time to fracture were evaluated. Data were subjected to one-way analysis of variance and Bonferroni t-test procedure with a significance set at P < 0.05.
Results: No instruments were broken during preparation of root canals. Two TF Adaptive green and 5 yellow showed unwinding after intracanal clinical use. No statistically significant differences were found between green instruments of both groups (P > 0.05), while a statistically significant difference was found between the yellow instruments (P < 0.05), with group B showing an higher resistance to cyclic fatigue.
Conclusions: A prolonged passive brushing motion did not adversely affected mechanical resistance of the instrument used for this purpose. Resistance to both deformations and cyclic fatigue of the second instrument within the TFA small sequence was enhanced by the coronal flaring provided by the brushing action of the first instrument used.

AIMS To define if the new portable appliances, like smartphone, iPad, small laptop and tablet can be used in cephalometric tracing without dropping out the validity of any measurement. METHODS We investigated and compared the reproducibility and the speed of landmarks identification process on lateral X-rays in two input devices: a mouse-driven cursor and a pen used as input means in mobile devices. One expert located 22 landmarks on 15 lateral X-rays in a repeated measure design two times, at time T1 and T2, after at least one month. The Intraclass Correlation coefficient was used to evaluate the reproducibility for each landmark tracing and the agreement between the value derived from both input devices. Also, the mean errors in measurements, the standard deviation and the Friedman Test significans (P < 0.05) between both input were statistically evaluated. RESULTS All landmarks had a high agreement and the Friedman Test indicated statistically significant differences (P<0.05) for the identification of Na, Po, Pt, PNS, Ba, Pg, Gn, UIE, UIA, APOcc and PPOcc landmarks. CONCLUSIONS Even if the mouse input give higher agreement for landmark tracing the differences are really minimal and they can be ignored in private practice. We suggest the adequacy of pen input in clinical setting.

Background: Overheating during implant site preparation negatively affects the osseointegration process as well the final outcome of implant rehabilitations. Piezoelectric techniques seem to provide to a gentle implant preparation although few scientific reports have investigated the heat generation and its underlying factors.
Purpose: To investigate, through a proper methodological approach, the main factors influencing temperature rise during piezoelectric implant site preparation.
Materials and methods: Different piezoelectric tips (IM1s, IM2, P2-3, IM3, Mectron Medical Technology, Carasco, Italy) have been tested. The experimental set-up consisted in a mechanical positioning device equipped with a load cell and a fluoroptic thermometer.
Results: The first tip of the sequence (IM1s) generated the highest temperature increasing (ΔT). The diamond tips (IM1s and P2-3) determined higher ΔT values than the smooth tips (IM2 and IM3). Further tests with IM1s suggested that the temperature elevation during the first thirty seconds may be predictive of the maximal temperature as well as of the overall thermal impact.
Conclusions: Working load, working movements management and bone features resulted to be the main factors influencing temperature rise during piezoelectric implant site preparation. Irrigant temperature and clogging effect may also synergically contribute to the heat generation.
背景:种植体准备过程中的过热会对骨整合过程以及种植体康复的最终结果产生负面影响。压电技术似乎提供了一种温和的种植体制备，尽管很少有科学报道研究了热量的产生及其潜在因素。目的:通过合理的方法，探讨影响压电种植体部位制备过程中温升的主要因素。材料和方法:已经测试了不同的压电尖端(IM1s, IM2, P2-3, IM3, Mectron Medical Technology, Carasco, Italy)。实验装置包括一个配有称重传感器和荧光光学温度计的机械定位装置。结果:序列的第一尖端(IM1s)产生了最高的升温(ΔT)。金刚石尖端(im1和P2-3)比光滑尖端(IM2和IM3)确定更高的ΔT值。对im1的进一步测试表明，前30秒的温度升高可以预测最高温度以及总体热影响。结论:工作负荷、工作动作管理和骨骼特征是影响压电种植体部位制备过程中温升的主要因素。灌溉温度和堵塞效应也可能协同促进热的产生。

Objective: Specific regulations about education and training for body piercing licensure courses have to be considered due to the great increase in oral piercing practices. The aim of the present survey was to assess the local and systemic risk awareness in the practice of oral piercing and their prevention in a sample of Italian piercers.
Materials and methods: An anonymous 20-item questionnaire was administered to 30 body licensed piercers in a small town of central Italy. Licenses certificates were issued by Lazio Region after the completion of an approved training program for standard body piercing including 90 hours of course and a final examination as provided by regional law. The questionnaire surveyed on oral cavity anatomy, local and systemic risks as result of oral piercing, piercing maintenance and need of a dental visit.
Results: Response rate was 66.6%. Only 20% of respondents was aware about oral cavity anatomy and none had knowledge about tongue and gums anatomy. Only 10% enlightened the need of a dental visit and 30% was aware about piercingrelated temporary paralysis. The piercing maintenance was habitually proposed only by 40% of respondents.
Conclusion: The study participants showed a low level of awareness regarding the potential health risks of oral piercing. Poor knowledge of anatomy and local and systemic risks and poor awareness of the importance of piercing maintenance explanation.

Aim: The aim of this study is to present 18 months follow-up results of porous tantalum trabecular metal-enhanced titanium dental implant (PTTM) in implant supported prosthesis in post-oncological patients.
Materials and methods: A total of 25 PTTM implants were placed in each jaw of 6 patients that met specific inclusion and exclusion criteria. Resonance Frequency Analysis (RFA) was conducted and Implant stability was recorded in ISQ values (Osstell ISQ, Osstell AB, Goteborg, Sweden) at implant placement and after 2,4,6,12 and 18 months of functional loading. Mean bone loss was also evaluated at the same interval of time on each periapical radiographs, bone levels were calculated by measuring the distance from the implant shoulder to the first bone to implant contact.
Results: Cumulative implant survival rate is 100% (n=25/25) to date and mean ISQ values recorded were: 72.14±5.61 (range= 50-81) at surgery, 64.39±8.12 (range=44-74) after 2 months, 74.26±7.14 (range=44-74) after 4 months, 76.84±7.65 (range=60-83) after 6 months, 78.13±4.14 (range=64-84) after 12 months and 80.22±6.23 (range=68-89) after 18 months of functional loading. Mean crestal marginal bone loss was 0.19±0.25 mm after 2 months of functional loading on periapical radiographs, 0.22±0.4 mm at 4 months, 0.3±0.46 mm at 6 months, 0.57±0.62 at 1 year and 0.64±0.60 mm after 18 months.
Conclusions: The results of this study, even if limited by the number of implants placed indicate that PTTM dental implants have a clinical efficacy in prosthetic rehabilitation of post-oncological patients, due to trabecular structure of the porous Ta metal that increases bone-implant connection values.
目的:观察多孔钽小梁金属增强钛牙种植体(PTTM)在肿瘤后种植体支持修复中的18个月随访结果。材料和方法:6例符合特定纳入和排除标准的患者，每个颌骨共放置25个PTTM种植体。进行共振频率分析(RFA)，并记录种植体放置时和功能负荷2、4、6、12和18个月后的ISQ值(Osstell ISQ, Osstell AB, Goteborg, Sweden)。在每个根尖周x线片上评估相同时间间隔的平均骨质流失，通过测量从种植体肩部到种植体接触的第一根骨的距离来计算骨水平。结果:到目前为止，累积种植体存活率为100% (n=25/25)，记录的平均ISQ值为:手术时72.14±5.61(范围= 50-81)，2个月后64.39±8.12(范围=44-74)，4个月后74.26±7.14(范围=44-74)，6个月后76.84±7.65(范围=60-83)，12个月后78.13±4.14(范围=64-84)，18个月后80.22±6.23(范围=68-89)。根尖周x线片显示，2个月功能负荷后的平均嵴边缘骨损失为0.19±0.25 mm, 4个月0.22±0.4 mm, 6个月0.3±0.46 mm, 1年0.57±0.62 mm, 18个月后0.64±0.60 mm。结论:本研究结果表明，即使受植入数量的限制，PTTM牙种植体在肿瘤后患者的修复康复中具有临床疗效，因为多孔Ta金属的小梁结构增加了骨-种植体的连接值。
