RESUMO
Although arthrocentesis is an accepted safe treatment modality for the management of temporomandibular disorders (TMD) in symptomatic patients, the benefit of hyaluronic acid (HA) injections remains uncertain. The aim of this study was to evaluate whether intra-articular HA injections adjunctive to arthrocentesis can be more effective than other medications for the improvement of TMD associated symptoms. Additionally, the impact of HA injections on quality of life of TMD patients was assessed with SF-36® questionnaire in a cohort of patients. An electronic search of Medline, Scopus and Cochrane databases was performed up to March 2020. The following search terms were used: "arthrocentesis", "hyaluronic acid", "intra-articular injections", "visco-supplementation", "temporomandibular disorders". Prospective and retrospective studies that reported the application of HA injections compared to other intra-articular drugs for the treatment of temporomandibular disorders were included. Systematic or narrative reviews and pre-clinical studies were excluded. Additionally, a retrospective clinical study was performed for evaluation of changes in quality of life before and after arthrocentesis with HA injections. In the systematic review, the initial search yielded 1327 articles. After screening of the titles, abstracts, and full texts, 29 studies were selected (26 randomized studies, 2 controlled clinical trials, 1 retrospective report). In the clinical study, 12 patients were included. Intra-articular injections of HA and other medications together with arthrocentesis seemed to be beneficial for improvement of functional symptoms of TMD and pain. The case series also supported the efficacy of HA injections showing an improvement of quality of life of these patients. However, from literature review, it was impossible to identify an optimum drug or a protocol for predictably improving the pain and/or functional symptoms of temporomandibular problems, due to different etiologies, diversity of treatment modalities and conflicting results. In conclusion, there is no consensus in the literature that HA injections shows better results in comparison with other treatment modalities. According to the results of the present clinical study, HA injections with/without arthrocentesis seems to be beneficial in terms of clinical symptoms and quality of life of the TMD patients.

The aim of this retrospective case series was to evaluate the clinical and radiographic outcomes of the patients that underwent implant surgery with a modification of the sinus lift summers protocol. Forty healthy patients in need for oral rehabilitation with dental implants were included in this study. Inclusion criterion was the need for extraction of one compromised tooth due to persistent abscess/ periodontitis/cyst in the atrophic posterior maxilla region. The treatment consisted of two stage surgery for all patients. In the first stage, after tooth extraction, the sockets were preserved with allogenic bone graft and equine collagen membrane. After 4-5 months, 40 implants with a sandblasted surface, were inserted with osseodensification technique and a modification of the Summers sinus lift protocol for fracturing the sinus floor. The implant survival rate was the primary outcome. Intra- and postoperative complications were additional criteria for success. The mean follow-up from implant surgery was 28.0±7.3 (standard deviation) months (range 17.8-43.4 months). One implant was lost before the delivery of the prosthesis. The overall implant survival rate was 97.5%. The overall mean peri-implant marginal bone level change after 6 and 12 months of function was, respectively, 0.26±0.24 mm (95% CI: 0.19, 0.34 mm) and 0.71±0.36 mm (95% CI: 0.60, 0.82 mm). Marginal bone loss was statistically significant at both time frames respect to implant placement, and also the difference between 6 and 12 months was significant (p<0.001 in both cases). No biological nor mechanical complications were recorded throughout the observation period. As a conclusion, the technique presented in this cohort study can be an effective and safe alternative to standard maxillary sinus floor augmentation procedures and immediate implant insertion protocol, especially in cases of periodontitis and infected sites, which can represent a high risk for implant failure in patients with atrophic posterior maxilla.

The objective of the research was to evaluate the location, size, variability, and morphologic features of mental foramen (MF) and the inferior alveolar nerve canal (IAN) on cone-beam CT. We evaluated the morphologic findings of mental foramen (MF) and inferior alveolar nerve (IAN) canal of 88 mandibular hemiarches of 65 Caucasian subjects (35 males, 30 females; age range 25-75 years) using cone beam CT. The most common horizontal position of MF was type 3 (53.4%), followed by type 4 (39.8%), type 1 (2.3%), type 2 (2.3%), and type 5 (2.3%). Regarding the vertical position, in 71.6% of cases (63/88) we found type 3 position, followed by type 2 (22.7%) and type 1 (5.7%). MF presented as oval in 51.1% and round in 42%, with double oval and triple foramens having been observed in 5.7% and 1.1% respectively. In 36.9% of cases, we found an anterior loop of the IAN. The mean depth of MF was 6.12±1.65mm; width and height were 3.7±0.83mm and 3.14±0.78mm. Width and height of the IAN distal to MF were 2.27±0.53mm and 2.74±0.51mm, while those of the incisive nerve canal mesial to MF were 1.37±0.44mm and 1.54±0.58mm, respectively. An increase in the width of MF was correlated to oval shape (r=0.45; P < 0.01), and there was a low but significant correlation (r=0.23; P < 0.05) between the round shape of MF and the size of the IAN. MF shape appears to be correlated to MF width and size of the IAN. The individual anatomical variability of this structure is a factor that must be considered when dealing with mandibular surgery.

Pain, bad taste, and impaired daily activity after implant therapy are common sequelae. Concentrated growth factors (CGF) are a platelet concentrate with a favourable effect on wound healing, but there is still no evidence regarding its potential benefits for reducing postoperative pain and symptoms. Therefore, aim of this prospective comparative study was to determine the effect of CGF on quality of life (QoL) of patients after implant therapy. Fifty-two consecutive patients with one missing mandibular molar were included in the study and alternatively assigned to two groups. Control group received standard implant treatment, and test group received CGF associated with implants. Standard periapical radiographs were taken before and after procedure. Post-operative care consisted of 0.2% chlorhexidine digluconate solution twice daily for 10 days. A QoL questionnaire (OHIP-14) for bad taste, pain and limitation in daily activities was filled and returned one week post-operatively. Daily pain was also assessed through Visual Analogue Scale (VAS) on a 1-100 scale. Parametric test (chi-square) was performed to compare the results of the questionnaire between the two groups using STATA statistical software. All patients correctly filled and returned the questionnaire. Significantly higher proportions of patients of test group reported no bad taste, pain, and limited activity, (24/26, 13/26, and 25/26, respectively) respect to control. Postoperative pain with VAS score was significantly lower in the test group on day 1, 2, and 3 as compared to control. CGF positively influenced QoL when associated with implant rehabilitation of mandibular molars, minimizing post-operative discomfort.

Geographic tongue (GT) represents a localized type of psoriasis inversa and its burden of dermatological and oral comorbidities frequently conditions its severity and diagnosis. Currently, no epidemiological studies have evaluated GT muco-cutaneous comorbidities. We aimed to study oral and dermatological comorbidities in a large sample of GT patients. In this multicenter, cross-sectional study, involving 4 primary referral centers in Italy, we evaluated adult GT patients, who were assessed by board certified dermatologists and dentists for 5 months and collected demographics and medical history. GT was evaluated using Hume's classification together with Geographic tongue severity index (GTASI) to score its severity. The prevalence of oral and dermatological comorbidities was recorded. In the sample we enrolled 137 GT patients (M/F= 5:1) with a mean age of 48,2 ± 14,7 yoa and 33.6% had GT family history. The clinical evaluation found 96 (70.1%) GT type I, 7 (5.1%) type II, 13 (9.5%) type IIIa, 19 (13.9%) type IIIb, 2 (1.5%) type IV, following Hume's classification. The mean GTASI score was 23,7 ± 14,2 and the vast majority displayed a severe form of GT. Eighty-nine patients had oral comorbidities (burning mouth syndrome, caries, parulid and lichen planus) and 80 had dermatological concurrent conditions (plaque psoriasis, inverse psoriasis and atopic dermatitis). In GT patients, both dermatological and dental evaluation should be mandatory to identify previously undiagnosed mucocutaneous comorbidities.

Geographic tongue (GT), a form of inverse psoriasis, is frequently linked to plaque psoriasis. The objective of the study is to evaluate IL-17 blocker (secukinumab) effect on GT severity. This reallife, multicenter, retrospective observational pilot study evaluated patients with plaque psoriasis and concomitant GT that started in label treatment with secukinumab. Patients were evaluated twice (T0=baseline and T1=after 16 weeks) by a dentist and a dermatologist collecting data on cutaneous Psoriasis Area Severity Index (PASI) and oral statuses using Hume's classification of the Geographic Tongue Severity Index (GTASI). Twenty-nine psoriatic patients with GT treated with secukinumab were enrolled for the study. Seventeen patients display type I GT, 6 type II and 6 type III with an overall GTASI of 25.52±9.57 at the baseline (T0). No correlation was found between delta GTASI and delta PASI (r=-0.27, p=0.1551). GTASI decrement from T0 to T1 was statistically significant ([95%CI -26.64 to -19.56], t=-13.36, p<0.0001). Secukinumab may enter in GT therapeutic armamentarium as the first biologic IL-17 blocker in patients with concomitant moderate-to-severe plaque psoriasis.

PURPOSE: To assess the clinical and radiographic success rate of microsurgical endodontic treatment of upper molar teeth in relationship with the maxillary sinus, with 12 months follow-up. METHODS: Patients treated with microsurgical endodontic treatment of upper molar teeth in the period between 2017 and 2019 were recruited from two dental clinics according to specific selection criteria. The outcomes were determined based on clinical and radiographic results taken three, six and 12 months post-operatively, compared with those taken immediately before and after surgery. Clinical and radiographic outcomes were recorded. The distance between the most apical part of the root and of the lesion to the maxillary sinus was measured on CBCT images before the surgery. Patient-related outcomes were recorded. RESULTS: Out of 35 patients evaluated, 21 were selected according with the selection criteria for a total of 27 roots and 29 canals treated. After 12 months, 18 patients showed a complete healing whereas three demonstrated incomplete healing. Consequently, the success rate in this study was 85.7% after one year. In 28.5% (6 patients) there was a perforation of the Schneiderian membrane that didn't seem to affect the outcome. All patients kept the molar one year later. The pain level decreased significantly over the time during the first week after surgery. CONCLUSION: Microsurgical Endodontic treatment of the upper molar teeth should be considered a valid and predictable treatment option even in case of Schneiderian membrane perforation. Future clinical studies with a larger sample size are needed to compare the results obtained.

Obstructive sleep apnoea syndrome (OSAS), which is characterised by repetitive episodes of pharyngeal collapse during sleep, is gaining much attention because of the important deleterious consequences it might have on the patient's health. We therefore organised a retrospective longitudinal study to report the long-term follow-up of maxillomandibular advancement (MMA) as a treatment for OSAS. A total of 19 patients with severe OSAS was treated during the period 2007-2016. They were followed up six months postoperatively (T1) and after a mean follow up of 6.7 (range 4-10) years (T2, between November 2017 and February 2018) for the polysomnography variables, and the Epworth sleeping scale (ESS) and body mass index (BMI) were recorded. All polysomnographic variables improved significantly from baseline to T1 and from baseline to T2. The ESS significantly improved from baseline to T2. Nearly all patients at T1 and over two-thirds at T2 had a 50% reduction of the apnoea/hypopnoea index when compared with baseline, and a value lower than 20 of the same index. The BMI did not change significantly from T0 to T2. Our long-term follow-up has documented the stability of the outcomes of the MMA for the treatment OSAS.

BACKGROUND: The aim of the study was to evaluate the use of enamel matrix derivative (EMD) alone or in association with deproteinized bovine bone mineral (DBBM) for the treatment of partially contained intrabony defects. METHODS: A total of 20 two-walled intrabony defects belonging to nine patients were included. Ten defects were treated with EMD alone (test group 1) and the other 10 were treated with EMD and DBBM (test group 2), applying either modified papilla preservation technique or simplified papilla preservation technique. RESULTS: Twelve months after surgery, in the test group 1, PD was 2.8 ± 0.8 mm, REC was 2.3 ± 2.4 mm and CAL was 5.0 ± 2.8 mm, significantly reduced from baseline values (P < 0.05). Likewise, in test group 2, PD, REC and CAL reduced to 3.0 ± 0.7 mm, 3.9 ± 1.5 mm and 6.9 ± 1.1 mm respectively, from baseline values at 12 months (P < 0.05). No significant differences between groups were found. CONCLUSIONS: The results showed that the use of EMD alone and the use of a combination of EMD and DBBM for the treatment of partially contained defects showed comparable clinical and radiographic outcomes after 12 months.

Aim of this retrospective study was to evaluate the one-year clinical and radiographic outcomes of implants with a triangular shaped neck inserted immediately after tooth extraction in esthetic zones. Patients in which immediate postextraction implants were placed and restored in the anterior maxilla, who underwent a Cone Beam Computed Tomograpy (CBCT) at baseline and after 12-16 months were included. The socket was preserved using deproteinized bovine bone to fill the buccal gap, and a resorbable collagen membrane. One-year implant survival and prosthesis success were evaluated. Hard and soft tissue stability was assessed by measuring various parameters on CBCT images. Clinical evaluation was also performed and Pink Esthetic Score (PES) assessed. Data from baseline and one-year follow-up were statistically compared using paired tests and a significance threshold of p=0.05. Twenty patients (13 males, 7 females, mean age 50.42±11.35 years) were included. Each contributed with one implant. No implant was lost. A significant improvement in PES was detected. Excellent hard and soft tissue preservation was observed after one year of function. Immediate placement of implants with a triangular shaped neck after tooth extraction, can be a suitable solution even for areas with a high aesthetic demand, such as the anterior maxilla.

INTRODUCTION: Inadequacy of residual bone height due to sinus pneumatization and alveolar bone remodeling could jeopardize the option for implant supported rehabilitation in posterior atrophied maxillae. AIM: The aim of this prospective, multi-centric clinical study is to investigate and assess the survival rate of short implants in single posterior maxillae atrophied sites with adjacent natural teeth, when augmented with leukocyte and platelet-rich fibrin (L-PRF) alone using a minimally invasive trans-crestal approach. MATERIALS AND METHODS: Seventy-four short implants were installed in 53 patients with residual bone height (RBH) <4mm using piezoelectric ultrasonic guided sinus elevation by transcrestal approach. Six perforations of the sinus membrane occurred (11.3% perforation rate), out of which five were managed by using just L-PRF as grafting material. Postoperatively, the implants were clinically evaluated for survival rate. The cumulative implant survival rate was 93.3% at the end of first year of follow-up. Considering 2 dropouts by the end of 2nd year follow-up, and no further implant loss, the cumulative survival rate remained 93.3% up to 5 years follow-up period. DISCUSSION: The use of L-PRF plug as grafting and careful preparation of osteotomy site with piezoelectric ultrasonic device could allow for simultaneous crestal sinus floor elevation and short implant installation in posterior atrophied maxillae with RBH <4mm, extending the indications for implant rehabilitation.

This study investigates the characteristics of load transmission to bone of alternative treatments for posterior maxilla edentulism with relatively limited available bone volume. Implant shape (conical and cylindrical), augmentation technique and the effect of bone-graft stiffness were taken into consideration. The finite element models of the atrophic sinus implanted with short implant were compared to two grafted-sinus models implanted with longer implants, engaged bicortically. Bone-graft stiffness was varied to describe different stages of graft-maturation (from short-term to long-term). Stress and load distributions due to axial and bending loads were compared on the bony structures. In the short-term, axial force is supported almost equally by the cortical layers and the trabecular core, while a bending load is mainly supported by the crestal cortical layer and secondarily by the cortical floor, the bone-graft supported a negligible load. Bicortical engagement produces higher load transfer to the cortical floor under axial load. In the long-term, as the stiffness of the bone-graft increases, the load is transferred progressively towards the grafted region, progressively unloading other structures, particularly the internal cortical layer.

The aim of this study was to investigate the success of the combination of short implants, osteotome sinus floor elevation technique (OSFE) and pure platelet rich plasma (P-PRP), for the rehabilitation of atrophic posterior maxilla. Fifty-one patients were included in this study, receiving a total of 88 short implants in three different lengths (6.5 mm, 7.5 mm, 8.5 mm), depending on the residual bone height level. A total of 39 standard implants were also inserted when judged necessary, and splinted with one or more short implants in order to support a fixed prosthesis. Data were recorded in a one-year and five- year follow-ups. No statistically significant difference was found between short implants with different length, nor between short and standard length implants in terms of both bone level change and bone height. Based on the present results, the use of short implants combined with OSFE technique for the rehabilitation of atrophic posterior maxilla can be recommended.

The only cutting technique used for osteotomies in orthognathic surgery for many years has been a saw, but recently piezoelectric surgery has been introduced as a possible alternative. The aim of this study was to find out if piezoelectric surgery can be more comfortable for patients having orthognathic surgery. A total of 25 patients with dentofacial deformities (seven male and 18 female), were treated from January 2016 to September 2017. In 11 patients, osteotomies were made using a conventional saw, while in 14 a piezoelectric device was used. The variables assessed were: operating time, postoperative swelling, postoperative pain, and cutaneous sensitivity of the upper and lower lips. The duration of operation for the piezosurgery group was significantly longer than that for controls, but the patients had less swelling at all follow-up visits, and the difference was significant at the 30-day follow-up (p=0.045). Those who had piezosurgery had significantly less pain at the three-day follow up (p=0.035). There was a significant difference in cutaneous sensitivity only for the right side of the upper lip and only at the one-day follow-up. We conclude that piezoelectric surgery offers some advantages in lessening swelling and the perception of pain after orthognathic surgery, but further investigations are required.

Objectives The aim of this study was to evaluate the patients' willingness to pay (WTP) values and preference for the treatment of a tooth with very poor prognosis, among two options: root canal therapy and crown positioning or tooth extraction, implant insertion and crown positioning.Methods A total of 103 patients were recruited from a private dental clinic and interviewed. A questionnaire measured individuals' preferences among the two alternative treatments for a tooth with poor prognosis and the maximum amount of money they would be willing to pay for their choice with a starting bid of [euro]2,000 in [euro]100 increment/decrement. Demographic data, patient choice, median values and WTP association with socio-demographic factors (Student ttest and one-way ANOVA) and correlation between variables (Pearson chi-square test) were revealed.Results Seventy-six percent of patients expressed a preference for root canal therapy, while the remaining 24% chose the dental surgery. A fair agreement between previous experience and current therapeutic choice was found (P = 0.0001). The WTP median value was [euro]2,000 and 46% of participants would pay an additional sum of money for the therapy (median: [euro]300). The preferred treatment was influenced by previous experience, but no association was found between WTP values and socio-demographic factors.Conclusion Patients tend to prefer a conservative approach for the treatment of a tooth with poor prognosis and are willing to pay an additional fee to receive their treatment choice.

AIM: This study presents the use of a modern surgical endodontic technique for the treatment of altered sensation following extrusion of endodontic filling materials. CASE PRESENTATION: A patient presented with an altered sensation following a root canal treatment and extrusion of root filling material at the mandibular canine and lateral incisor. She was treated using a modern surgical technique that included removal of the extruded filling materials followed by root-end management and obturation. The treatment resulted in complete periapical and neurosensory healing. CONCLUSIONS: Modern endodontic surgery may be beneficial for patients with nerve injury due to extruded endodontic filling materials, since it enables a relatively safe removal of the irritating extruded endodontic materials, proper root-end management and preservation of the natural tooth.

AIM: To compare the impact of rotary and reciprocating instrumentation on postoperative quality of life (POQoL) after single-visit primary root canal treatment. METHODOLOGY: A randomized controlled clinical trial was designed and carried out in a University endodontic practice in northern Italy. Healthy subjects with asymptomatic irreversible pulpitis, symptomatic irreversible pulpitis or pulp necrosis with or without apical periodontitis (symptomatic or asymptomatic) scheduled for primary root canal treatment were enrolled. Single-visit root canal treatment was performed with ProTaper™ S1-S2-F1-F2 (rotary group, n = 23) and WaveOne™ Primary (reciprocating group, n = 24). Irrigation was performed with 5% NaOCl and 10% EDTA. Root canal filling was performed with the continuous-wave technique and ZOE sealer. POQoL indicators were evaluated for 7 days post-treatment. The variation of each indicator over time was compared using anova for repeated measures (P < 0.05). The impact of each variable on POQoL was analysed with a multivariate logistic regression model (P < 0.05). RESULTS: Pain curves demonstrated a more favourable time-trend in the rotary group (mean, P = 0.077; maximum, P = 0.015). Difficulty in eating (P = 0.017), in performing daily activities (P = 0.023), in sleeping (P = 0.021) and in social relations (P = 0.077), was more evident in the reciprocating group. Patients' perception of the impact of treatment on POQoL was more favourable in the rotary group (P = 0.006). Multirooted tooth type and pre-existing periradicular inflammation were associated with a decrease in POQoL. CONCLUSION: Reciprocating instrumentation affected POQoL to a greater extent than rotary instrumentation.

OBJECTIVES: The aim of this study was to make a comparative evaluation of professional oral hygiene with or without the adjunct of glycine air-powder system for the treatment of peri-implant mucositis. METHODS: After the application of inclusion and exclusion criteria, patients were divided in two groups: in control group, patients were treated with professional oral hygiene manoeuvres (POH) while in the test group, glycine air-powder system (SGA) was adjuncted to professional oral hygiene. Probing depth (PD), bleeding index (BI) and plaque index (PI) were measured at baseline, and 3 and 6 months after the treatment. RESULTS: A total of 30 patients (15 per group) were selected for the study. In POH e SGA group, PD was, 2.86 ± 0.37 and 3.00 ± 0.36 mm at baseline, 2.90 ± 0.53 and 2.62 ± 0.50 mm after 3 months, 2.96 ± 0.56 and 2.41 ± 0.54 mm after 6 months, respectively, significantly lower in SGA group in the last follow-up visit. In both groups, both PI and BI decreased over time. CONCLUSIONS: The present reports showed that both techniques were useful for the treatment of peri-implant mucositis. In the test group (with glycine powder), a significant reduction of probing depth was observed.

AIM: Aim of this paper was to present the therapeutical approaches to the management of the immature apex and discuss the evolution of materials and techniques. METHODS: A Medline search was performed limited to human studies published. The keywords searched were apexogenesis, apexification, pulp regeneration, revascularization. RESULTS: Apexogenesis and apexification techniques using Calcium hydroxide or MTA give a high succes rate. Recent regeneration procedures may be helpful for apexification in non vital elements. CONCLUSION: Calcium hydroxide is the gold standard material used in apexogenesis and apexification. New technologies are promoting the growing interest in strategies used for vitality preservation and pulp regeneration.
