Background Amelogenesis Imperfecta (AI) is a syndromic entity comprising several clinical conditions, mostly genetic-based, affecting quality and quantity of enamel. The use of digital tools can be advantageous to enhance communication between the dental team and patients. Moreover, a full digital approach would allow to check each single clinical step according to the treatment plan with a backward approach. The aim of this case report is to describe a multidisciplinary treatment program of a young patient with severe open bite and amelogenesis imperfecta, whose restorative rehabilitation was planned in a full-digital workflow, from the initial communication phase up to the final prosthodontic rehabilitation. Case report An 8-year old female patient was diagnosed with a Class II division 1 malocclusion, severe open bite and AI. The treatment plan included 3 phases: the elimination of the tongue interposition habit and the anterior open bite, the orthodontic correction of dental deviation and leveling of both dental arches and a prosthetic rehabilitation. The extraction of the four first molars corrected the canine and molar Angle Class II relationships, deviation of the midline and repositioning of the maxillary incisors on the sagittal plane. Feldspathic ceramics was used in anterior sites to enhance the esthetic outcome. CAD/CAM hybrid ceramo-polymeric restorative material (PICN) was chosen for posterior regions. Conclusion The outcomes of the present case report proved that the planned objectives were satisfactorily obtained thanks to proper treatment planning, full digital workflow and the patient’s optimal compliance with the extraoral device.

Aim This study was conducted to evaluate the marginal crestal bone loss around immediately loaded one-piece vs. two-piece dental implants associated with two different loading protocols during the first year after implant insertion. Materials and methods Eighty-six patients participated in the study; 90 dental implants (Zimmer Dental) were used. Of those, 30 were Tapered Screw Vent (TSV) implants with an immediate loading protocol (TSVi), 30 TSV with delayed loading (TSVd), and 30 were one-piece implants with an immediate loading protocol (OP). Crestal marginal bone loss in the coronal area of dental implants was evaluated radiographically at three months and one year post-implant insertion. Results Marginal bone loss was significantly higher after one year post-surgery compared to three months post-surgery in all the study groups. The mean values of marginal bone loss obtained by TSV implants were higher than those obtained with OP implants at both follow-up points. TSVd implants experienced the higher crestal marginal bone loss among all the study groups at both three months and one year. Conclusions Crestal marginal bone loss in the most coronal part of one-piece implants is significantly less than the marginal bone loss observed in tapered screw vent implants with either immediate or delayed prosthetic loading protocols with single implant crown rehabilitations. However, further studies with a longer observational time and larger sample are necessary.

Aim The present study aimed to evaluate the feasibility and efficacy of neoadjuvant chemoradiotherapy (NACRT) followed by definitive surgery and free fibular transfer in advanced stage oral squamous cell carcinoma patients. Methods Patients diagnosed with resectable oral squamous cell carcinoma, Stage IVa were enrolled for the study. The patients underwent a planned protocol of neoadjuvant radiotherapy and concurrent chemotherapy, insertions of dental implants in fibula followed by curative and reconstructive surgery. Objective response rate, overall survival, disease free survival and patient quality of life assessments were carried out. Results A total of eight patients with Stage IVa oral squamous cell carcinoma were enrolled for the study and treated according to the planned protocol. All patients completed neoadjuvant chemoradiotherapy and surgery; 6 (75%) patients achieved complete response while 2 exhibited partial response (downstaging) on post surgical pathological analysis. After a median follow-up time of 24.6 months and maximal follow up of 34 months, the overall survival was 75% and disease free survival was 87%. Two patients suffered from trismus and are currently undergoing oral physiotherapy. Six patients had orocutaneous fistula which healed. One had extrusion of fibular graft and two patients died. Conclusion The present study elucidates a treatment strategy for patients with locally advanced squamous cell carcinoma validated for better functional and aesthetic outcome with improved quality of life. Further evaluation is required in a bigger cohort size.

Aims Granulomatosis with polyangiitis (GPA) is one of the three primary systemic autoimmune vasculitis associated with anti-neutrophil cytoplasmic antibodies. In particular, GPA is characterized by inflammation of small and medium-sized blood vessels that may affect different organs, such as kidneys, lungs and, most commonly, upper respiratory tract. Lesions of the oral cavity, are represented by a group of non-specific lesions that include deep ulcers of tongue, cheek and palate with the presence of oro-antral fistulae, osteonecrosis of hard palate and labial mucosal nodules. However, the most pathognomonic GPA oral lesion is the so called “strawberry” gingival hyperplasia, a gingival swelling of reddish colour with scattered darker petechiae. Generally, such lesions are present in about 6-13 % of GPA patients; however, the recognition of oral lesions can help in establishing early diagnosis and treat the disease avoiding severe systemic involvement. Methods A literature review consisting of a thorough literature search was performed. Granulomatosis with polyangiitis (GPA) and oral lesions publications were selected from PubMed/Medline. The following keywords and MeSH headings were used for the search strategy: Granulomatosis with Polyangiitis, Wegener granulomatosis, antineutrophil cytoplasmic antibody associated vasculitis, mouth lesions, and strawberry gingivitis. Results Clinical and radiological features are important tools in early diagnosis, but mucosal biopsies of the upper respiratory tract are still the “gold standard” of GPA. Proper diagnosis is mandatory in order to successfully treat the pathology. Conclusions These findings underscore the importance of performing a complete oral examination, along with complete anamnesis and clinical evaluation, in all patients in whom GPA is suspected.

Aim The goal of this in vitro study was to evaluate the bond strength to radicular dentin of a new post in combination with two different luting resin materials and comparing it with a well known translucent post available on the market. Materials and methods A pilot study was conducted on 30 single-rooted extracted teeth, in order to study the link between the dentine-cement interface on the one hand and the post-cement interface on the other hand. Push out bond strength test was perfomed on two types of cement: Kuraray Panavia (Japan) and Gradia Core (GC Tokyo Japan) in combination with two types of fiber posts: Edelweiss post (Edelweiss Dentistry Products GmbH, Wolfurt, Austria) and GC Fiber Post (GC Gradia Core Tokyo Japan). Results According to the results of this study, the GC Post / Gradia Core group recorded push-out forces significantly higher than those of the groups in which the new post was used (p <0.05). Conclusion Within the limits of this in vitro study, it can be concluded that the highest values of adhesive strength in the push-out test were achieved by GC post/Gradia Core GC. Regarding the area of root that can produce the best push out bond strength, it clearly resulted that the coronal third of the root was the best substrate to lute posts.

Aim The present review was aimed to identify the surgical procedures to enhance the prosthetic prognosis in patients with mandibular defects. Methods A literature search was performed on the databases PubMed/Medline, Scopus, Embase, Google Scholar, Dynamed and Grey Literature, in addition to congress proceedings and books written in Italian or English language. The literature search was conducted using the following keywords: (“prosthesis” or “prosthetic”) AND “prognosis” AND “mandibulectomy”; (“prosthesis” or “prosthetic”) AND “prognosis” AND (“defect” or “reconstruction” or “resection”) and (“mandibular” or “mandible”). Results The selection process yielded 43 papers after the databases search, while 7 books and 3 congress proceedings were included after the manual search. Conclusion To enhance the prosthetic prognosis, the surgeons must preserve the tongue mobility and as many teeth as possible; vestibuloplasty could be needed, while intraseptal bone cuts and specific resection lines are recommended. The use of fibula graft, osseointegrated implants, and digital technologies can improve the prosthetic prognosis.

Aim The aim of the present study was to evaluate in an adult population the correlation between different methods for the evaluation of halitosis and investigate the influence of prosthetic rehabilitation on halitosis level. Materials and methods A sample of 50 adult patients was selected at the Dentistry Unit of the University of Rome Tor Vergata, Italy, who were divided in Group 1 (absence of prosthesis), Group 2 (fixed prosthesis), and Group 3 (removable prosthesis). The assessment of oral malodor was carried out by organoleptic evaluation, measuring the concentration of H2S, CH3SH, and (CH3)2S with Oral ChromaTM and quantification of salivary β-galactosidases (Sβ-g) activity through the spectrophotometric method. Statistics: Anova, Postdoc LSD test, Pearson’s correlation coefficient (P) and Spearman’s correlation coefficient (Rho) were used; p values less than 0.05 were considered significant. Results A positive and significant correlation between organoleptic evaluation, Sβ-g, levels of volatile sulfur compounds Oral ChromaTM measurements was found (p<0.05). By stratifying patients with and without a dental prosthesis, it was possible to show a significant increase of organoleptic scores (p<0.05), β-galactosidase (p<0.05), food stagnation (p<0.01) and a higher scores of H2S (p<0.05) and CH3SH (p<0.05) in patients wearing a prosthesis. Stratifying results between Groups 1-2-3, it was possible to see that some parameters were higher in Group 3, followed by Group 2. Conclusion The presence of prosthetic rehabilitation negatively affected halitosis in the patients according to both clinical and self-reported evaluations.

Aim This research was performed to evaluate the in vivo accuracy of flapless, computer-guided implant placement by comparing the three-dimensional position of planned and placed implants. Materials and methods In this retrospective study the results from a 1-year follow-up of a single-cohort of 15 patients (30 implants) are reported. A 3D planning software was used to determine the correct placement, considering the bone volume, the functional and the aesthetic prosthetic result. CAD/CAM technology was used to turn the virtual plan into the surgical guide. Results The statistical analysis showed a mean radial deviation of the implant head of 0.3 mm (SD 0.21), a mean radial deviation of the implant apex of 0.58 mm (SD 0.33), a mean depth deviation of the implant head of 0.37 mm (SD 0.29), a mean depth deviation of the implant apex of 0.43 mm (SD 0.25) and a mean angular deviation of the long axis of 2.87° (SD 1.99); the mean actual translation between the planned and the placed implant was 0.66 mm (SD 0.35) at implant platform and 1.04 mm (SD 0.47) at apex. Conclusion Flapless and computer-guided implant placement proved to be a reliable clinical option for an accurate implant insertion.

Transmigration of mandibular canine is an uncommon clinical condition in which impacted canine crosses the midline. Etiology of this phenomenon is unknown, but in some cases the presence of follicular cyst may be one of the causes. Canine transmigration is more prevalent in the mandible and women seem to be more affected than men. Mandibular canines play a crucial role in the oral cavity. Therefore, an early diagnosis is required, by the use of radiographs, especially orthopantomography or computed tomography. In case of transmigrated canine associated with follicular cyst, although several treatment options are described in literature, surgical extraction along with the enucleation of the cyst is the only treatment of choice. The present study describes the case report of a transmigrated canine associated with a follicular cyst located near the inferior border of the mandible in a 15-year-old female patient.

Aim Lithium disilicate is available in two formulations: press and block. The first requires an analog workflow, the latter a full digital workflow. The aim of this study was to evaluate clinical performance of two lithium disilicate systems by means of the novel Functional Index for Teeth (FIT) after one year of clinical service. Materials and methods Partial adhesive crowns on posterior teeth were made on 60 patients, who were randomly divided into two groups: Group 1 Initial LiSi Press and Group 2 Initial LiSi Block (GC Co., Tokyo, Japan), which therefore followed full analog and digital workflows respectively. The restorations were followed-up for 1 year, and the FIT evaluation was performed at baseline and at last recall. The FIT includes 7 variables: Interproximal, Occlusion, Design, Mucosa, Bone, Biology and Margins, that are investigated using an intraoral radiograph and occlusal and buccal pictures and evaluated using a 0-1-2 score as follows. The presence or not of major, minor or no discrepancy (‘Interproximal’, ‘Occlusion’ and ‘Design’), presence or not of keratinized and attached gingiva (‘Mucosa’), presence of bone loss >1.5 mm, <1.5 mm or not detectable (‘Bone’), presence or not of Bleeding on Probing and or Plaque Index (‘Biology’), presence of detectable gap and marginal stain or not (‘Margins’). The Mann-Whitney ‘U’ test was used and a level of significance at p<0.05. Also, “success” of the crowns (restoration in place without any biological or technical complication) and “survival” (restoration still in place with biological or technical complication) were evaluated. Results All FIT parameters had high scores, between 1.85 and 2, and no statistically significant differences between the two groups were found (p>0.05). No statistically significant difference was found between baseline and recall scores. All FIT scores were compatible with the clinical success and not one restoration was replaced or repaired. The success rate at 1 year was 100%. Conclusions The FIT can be a viable standardized evaluation of the quality of prosthodontic therapy. The two materials showed similar results at 1 year. Longer observation times are needed to confirm these preliminary results.
目的二硅酸锂有两种配方:压型和块型。前者需要模拟工作流，后者需要全数字工作流。本研究的目的是通过新型牙齿功能指数(FIT)在临床服务一年后评估两种二硅酸锂系统的临床性能。材料与方法对60例患者进行后牙部分粘接剂冠的制作，随机分为两组:第一组Initial LiSi Press和第二组Initial LiSi Block (GC Co.， Tokyo, Japan)，分别采用全模拟和全数字化的工作流程。修复体随访1年，并在基线和最后回忆时进行FIT评估。FIT包括7个变量:近端间、咬合、设计、黏膜、骨、生物学和边缘，使用口内x线片和咬合和颊片进行调查，并使用0-1-2评分如下。是否存在严重、轻微或无差异(“近端间”、“咬合”和“设计”)，是否存在角化和附着的牙龈(“粘膜”)，是否存在骨质流失>1.5 mm, 0.05)。基线和回忆得分之间没有统计学上的显著差异。所有FIT评分与临床成功相符，没有一个修复体被替换或修复。1年的成功率为100%。结论FIT是一种可行的、标准化的义齿治疗质量评价方法。两种材料在1年后显示相似的结果。需要更长的观测时间来证实这些初步结果。
