Resin bonded bridge technique was first introduced in 1963 by Rochette. It was the first type of non-invasive fixed dental prosthesis because the abutment tooth didn’t undergo any prior preparation. As early as 1996, Hussey and Linden studied cantilever resin bonded bridges and showed that there was no significant difference in the survival rates of a conventional bridge and cantilever resin bonded bridges. The main indications for a resin bonded bridge in children are post-traumatic edentulousness, during the early detection of agenesis and pre-implant temporization situations. Resin bonded bridges are also recommended in adults when the implant context is unfavourable or contraindicated (periodontal diseases and / or anatomical and prosthetic obstacles). Cantilever resin bonded bridge has many advantages compared to the traditional bridge: simpler and faster to make, more economical for the patient, easier hygiene and absence of partial detachment that can lead to secondary caries lesion.The preparation criteria will be adapted to the clinical situation, which will take into account the patient's age, the extent of edentulousness, the extent of occlusal loads and dental mobility. Thus, when the joint is subject to excessive stress, retention devices will complete the preparation. With the continuous development of materials as well as new minimally invasive treatment modalities, the alternative solution of the bonded bridge in the anterior region now corresponds to the realization of an all-ceramic zirconia cantilever bridge with a single wing.

Background. Conventional mechanical debridement alone cannot eliminate bacteria and their products from periodontal pockets. Adjunctive therapies improve tissue healing through detoxification and bactericidal effects. Photodynamic therapy (PDT) is a non-invasive treatment procedure that involves the use of a dye as a photosensitizer to attach to the target cell and be activated by a photon of an appropriate wavelength. This study aimed to assess the effectiveness of PDT in treating periodontitis as an adjunct to scaling and root planing. Methods. Fifteen subjects with chronic periodontitis were treated randomly with scaling and root planing (SRP), followed by a single PDT (test) or SRP (control) episode alone. Full-mouth plaque index (PI), sulcus bleeding index (SBI), probing depth (PD), and clinical attachment level (CAL) were assessed at baseline and 1-month and 3-month intervals. Microbiological evaluation of Porphyromonas gingivalis (Pg) in subgingival plaque samples was performed using a commercially available real-time polymerase chain reaction. Results. The results revealed a significant difference in PI, SBI, PD, CAL, and microbiological parameters between the groups one and three months after treatment. Conclusion. A combination of PDT and SRP gave rise to a significant improvement in clinical and microbiological parameters in patients with chronic periodontitis.

Background:The development of ceramics during the last years was overwhelming. However, the focus was laid on the hardness and the strength of the restorative materials, resulting in high antagonistic tooth wear. This is critical for patients with bruxism.Objectives:The purpose of this study was to evaluate the clinical performance of the new double hybrid material for non-invasive treatment approaches.Material and Methods:The new approach of the material tested, was to modify ceramics to create a biomimetic material that has similar physical properties like dentin and enamel and is still as strong as conventional ceramics.Results:The produced crowns had a thickness ranging from 0.5 to 1.5 mm. To evaluate the clinical performance and durability of the crowns, the patient was examined half a year later. The crowns were still intact and soft tissues appeared healthy and this was achieved without any loss of tooth structure.Conclusions:The material can be milled to thin layers, but is still strong enough to prevent cracks which are stopped by the interpenetrating polymer within the network. Depending on the clinical situation, minimally- up to non-invasive restorations can be milled.Clinical Relevance:Dentistry aims in preservation of tooth structure. Patients suffering from loss of tooth structure (dental erosion, Amelogenesis imperfecta) or even young patients could benefit from minimally-invasive crowns. Due to a Vickers hardness between dentin and enamel, antagonistic tooth wear is very low. This might be interesting for treating patients with bruxism.

Good Local Control

Aneurysmal bone cysts are benign bone tumors that usually present in childhood and early adulthood. They usually manifest as expansile osteolytic lesions with a varying potential to be locally aggressive. Since their first description in 1942, a variety of treatment methods has been proposed. Traditionally, these tumors were treated with open surgery. Either intralesional surgical procedures or <em>en</em> <em>bloc</em> excisions have been described. Furthermore, a variety of chemical or physical adjuvants has been utilized in order to reduce the risk for local recurrence after excision. Currently, there is a shift to more minimally invasive procedures in order to avoid the complications of open surgical excision. Good results have been reported during percutaneous surgery, or the use of embolization. Recently, sclerotherapy has emerged as a promising treatment, showing effective consolidation of the lesions and functional results that appear to be superior to the ones of open surgery. Lastly, non-invasive treatment, such as pharmaceutical intervention with denosumab or bisphosphonates has been reported to be effective in the management of the disease. Radiotherapy has also been shown to confer good local control, either alone or in conjunction to other treatment modalities, but is associated with serious adverse effects. Here, we review the current literature on the methods of treatment of aneurysmal bone cysts. The indication for each type of treatment along reported outcome of the intervention, as well as potential complications are systematically presented. Our review aims to increase awareness of the different treatment modalities and facilitate decision-making regarding each individual patient.

The significant growth in scientific and technological advancements within the field of dentistry has resulted in a wide range of novel treatment modalities for dentists to use. Photodynamic therapy (PDT) is an emerging, non-invasive treatment method, involving photosensitizers, light of a specific wavelength and the generation of singlet oxygen and reactive oxygen species (ROS) to eliminate unwanted eukaryotic cells (e.g., malignancies in the oral cavity) or pathogenic microorganisms. The aim of this review article is to summarize the history, general concepts, advantages and disadvantages of PDT and to provide examples for current indications of PDT in various subspecialties of dentistry (oral and maxillofacial surgery, oral medicine, endodontics, preventive dentistry, periodontology and implantology), in addition to presenting some images from our own experiences about the clinical success with PDT.

Objective: To assess the safety and efficacy of the Pellevé Wrinkle Treatment System as compared to LipiFlow, for treatment of dry eye syndrome due to meibomian gland dysfunction (MGD). Materials and Methods: In this split face, randomized study, ten patients who met specific criteria for inclusion were followed after treatment with the Pellevé Wrinkle Reduction System (what the authors have dubbed the "thermaLid Procedure") and a standard LipiFlow procedure performed the same day, with 1 and 3 months follow-up. Pre- and post- treatment MGD was assessed using a variety of subjective and objective measurements.   Results: The function of the meibomian glands improved significantly from baseline to 3 months for both thermaLid and Lipiflow treated eyes, with no significant difference between them, as measured by MGE grading, wax plug scoring, Standard Patient Evaluation of Eye Dryness (SPEED) and Ocular Surface Disease Index (OSDI) scoring. A significant change in conjunctival staining was found after both treatments at the 1-month time point but not the 3-month time point. thermaLid but not Lipiflow treatment, significantly decreased MARX line measurements at 3-months. Lipiview, Non-Invasive Tear Breakup Time (NITBUT), corneal surface staining, Tear Osmolarity, and anesthetic Schirmer's testing did not show statistically significant improvement, nor differences between treatment modalities. Conclusions: thermaLid treatment of the eyelids appears to show efficacy similar to Lipiflow treatment in reducing symptoms, reducing wax plugging and improving the number of functioning MGs as well as reducing conjunctival staining in MGD related dry eye disease.

Background: The aim of the study was to evaluate the management and outcomes of the patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a secondary hospital. Methods: A total of 699 hospitalized patients who had positive rRT-PCR for SARS-CoV-2 and/or typical findings of COVID-19 at chest computed tomography (CT) were enrolled in this study. Demographics, comorbities, initial laboratory tests on admission, treatment modalities, complications and outcomes were evaluated retrospectively. Results: The mean age was 57.0±15.6 (range:16-94 years), and male:female ratio was 1.24. 58.7% of the patients had at least one underlying comorbidity, the most common was hypertension. 72.8% of the patients had positive RT-PCR. 18.1% of the patients had lymphopenia, 35.7% hyperferritinemia, 58.3% increased lactate dehydrogenase, and 58.5% increased D-dimer. Chest CT revealed moderate and severe stage in 57.9% of the patients, and bilateral lung involvement in 78.7%. Hydroxychloroquine was given to 37.2% and favipiravir 67.1% of the patients. No significant difference was observed between treatment groups in terms of mortality (P=0.487). 5.8% of the patients were transferred to the ICU, of whom 75.6% were needed non-invasive and 36.5% invasive mechanical ventilation. The overall case fatality rate was 0.9. Conclusions: Older age, male sex, low lymphocyte count, CT findings including bilateral involvement and severe stage were significantly associated with poor prognosis and mortality.

e18544 Background: Malignant pleural mesothelioma (MPM) is a aggressive tumor that causes high mortality. Treatment of MPM remains disappointing, even new approaches are present today. Methods: The present study retrospectively examined the data related to 150 patients with MPM who were examined and treated in our center in Turkey from 2005 to 2012. The aims of this study were; to investigate clinicopathologic characteristics, treatment modalities and potential prognostic factors. Results: There were 87 males (58%) and 63 females (42%), 92 of the patients (61.3%) had an asbestos contact and this contact was generally environmental. Surgical resection (EPP or P/D) was used in 32 patients, 87 patients (58%) received only chemotherapy. The median progression free and overall survival (PFS and OS) for all patients were 10.6 and 14.8 months. There was no statistically significant difference between the patients who received pemetrexed/cisplatin (54 patients) and gemcitabine/cisplatin (28 patients) regimens in terms of the PFS and OS (p=0.145, p=0.244). The comparison between patients who were operated on and those who were not did not reveal any statistical difference in PFS and OS (p=0.416, p=0.095). There was no difference in both PFS and OS rates in comparison of patients who had P/D or EPP (p=0.87, p=0.652). Log rank analysis, ECOG performance status (p=0.018), histology (p<0.001), stage (p<0.001) and leukocytosis (p=0.005) were found to be significant prognostic factors in OS. At multivariate analysis, ECOG performance status (p=0.016), and stage (p<0.001) remained independently associated with OS. Conclusions: In survival analysis revealed significant differences in terms of both the PFS and OS, performance status, histology, stage and leukocytosis. EPP or P / D surgical options did not provide difference in term of survival. Survival rates in patients who received combining platinum analogues with pemetrexed or gemcitabine as front-line chemotherapy were found similar.

461 Background: Hypofractionated stereotactic Radiosugery (HFSR) is a non-invasive focused radiation treatment that delivers high dose therapy to cancer. HFSR for treatment of HepatocellularCarcinoma is analyzed in this prospective study. Methods: Twenty-three Hepatocellular Carcinomas (HCCs) were treated in 19 patients. All patients were prospectively evaluated before and after treatment. Age at treatment ranged from 11 to 84 years (mean 57) with 12 males and 6 females. Twenty-two percent of patients had prior chemotherapy, 17% had prior surgery and one patient had embolization. Tumor volumes ranged from 3 to 1,684cc (mean 312). The HCCs were treated with 500-800 cGy per fraction (median 600), in 5 or 6 fractions (median 5). For a total of 2,500-4,000 cGy (median 3,000). Cancers were followed with contrast CT and/or MRI scans and reviewed independently by radiologists. Control of the treated cancer is defined as cessation of growth, shrinkage or disappearance of the cancer after treatment. Results: Follow up ranged from 2 to 52 months. There was a 95.6% control rate at 14 months. By dose, volume, age, sex and prior treatment, there was no statistically significant difference in outcome. Conclusions: HFSR for HCCs is a generally well tolerated, non-invasive treatment modality with a high rate of local tumor control. Patients continue to be evaluated for longer follow up, progression free survival and overall survival. HFSR remains an attractive option for those in whom standard approaches have not produced desired results and for patients seeking an alternative to surgical or chemotherapeutic treatment.
