Abstract
Bone is a complexly structured tissue and hierarchically organized from macro to nano levels of dimensions. Biomaterial devices developed to replace and interact with bone tissues have been designed from the macro to nano perspective to provide suitable performance in acquiring primary and biological stability. Macro level designed features provide mechanical interlock and primary stability to implants inside the bone. Surface micro and nano structures influence cells behavior to promote the secondary or biological stability, reaching successful osseointegration.

Abstract
Bilateral coronoid process hyperplasia is a rare condition defined as an abnormal elongation of the mandibular coronoid process, formed of histologically normal bone. Coronoid process hyperplasia usually develops progressively, and the clinical symptoms are often similar to those of temporomandibular joint disorders (TMD). Therefore, it is often misdiagnosed as TMD initially. From 2013 to 2016, six patients were referred to our maxillofacial surgery unit by their dentist, to evaluate mouth opening with suspected TMJ disorder. Average age was 30 years No hypertrophy of the masseter muscles was found and the patient had no history of pain and/or dysfunction of the temporomandibular joint. Average maximal incisal opening was 16.3 mm. (Rance 13-20 mm). At the end of surgery the average mouth opening achieved was of 40.3 mm. After 6 months from surgery an average mouth opening of 41 mm was obtained, with no recidivism in the coronoid process growth or decrease in the mouth opening. The only successful treatment to restore the mouth opening caused by coronoid process hyperplasia is surgical correction of coronoid-malar interference by coronoidectomy or coronoidotomy. Commencement of physiotherapy is recommended to begin between three days and one week after surgery. We also recommend the use of the TeraBite®, a simple manual physiotherapy device.

Abstract
Eyelid reconstruction, though challenging, can produce a functional, esthetically pleasing lid. This should preferably be accomplished with a one-stage procedure, using robust, well-vascularized tissues similar to those being replaced, with minimal associated donor morbidity. According to the experience with Bichat pedicled flap in oral reconstruction, the authors propose the use of pedicle infraorbital fat pad for repair of conjunctival defect. Seven patients underwent eyelid reconstruction of full-thickness oncological or post-traumatic defects. In all cases, the reconstruction involved an orbital fat pad flap for the posterior lamella in addition to local flaps for the anterior lamella. All of the flaps survived. The transferred fat flap had a complete epithelization, histologically documented. No tumor relapse occurred in oncological cases. The results have been satisfactory both for clinical evaluation and for the patients. Reconstruction of the palpebral inner lamella with the orbital fat pad is a simple and low-morbidity procedure that has good morphological and functional results.

Abstract
The aim of this study is to present a new approach to the surgical treatment of fractures of the middle third of the face, based on the use of resorbable materials and stereolithographic models. From 2009 to 2014, we treated 10 cases of orbitozygomatic trauma mostly as secondary surgery. For each case, an anatomical replica had been produced simulating the expected result and was then used to contour the resorbable plates on its surface, even before the beginning of the surgical procedure itself. The plates and meshes already bended act as a guide to bony reduction procedure. No complications occurred: all patients healed well, without inflammatory reactions. The results obtained corresponded to the expected results. This technique has been employed for primary or secondary treatment of fracturesof the middle third facial, where it is not always easy to understand the displacement of bony segments and where the use of resorbables plates could be particularly beneficial, as they do not interfere with the maxillofacial skeleton physiology and avoid the necessity to remove plates and screws. Combined use of stereolithographic model and resorbable materials allow a new surgical approach based on the realization of the surgical procedure on the model, then transferred from the patient to the model, thanks to plates and meshes. This technique helps to overcome many of the limits of the conventional technique: the need of minimal surgical access, in order to minimize facial scarring and the vasculo-nervous structures that cross the head and neck district and the obligation to restore not only the morphology but also the biological functions.

Abstract
Diabetic patients are more prone to develop infections such as periodontal diseases. Bacteriotherapy with the concept of using good bacterial strains to replace the pathogenic ones emerged as a fascinating field due to the increasing incidence of antibiotic resistance. The aim of this study was to evaluate if a particular combination of probiotics (Lactobacillus Reuteri DSM 17938 and Lactobaciullus Reuteri ATCC PTA 5289) is useful in treating gingivitis in diabetic patients. Eighty adult patients with diagnosis of controlled diabetes type II and gingivitis were enrolled for this study and randomized in two groups. Only oral hygiene instructions were given. Bacteriotherapy (Lactobacillus Reuteri) was administered to test group. Outcome measures were presence of Plaque (P.I.) and Bleeding on Probing (B.O.P.). Data were collected at baseline and after 30 days. At 30 days, both groups showed a statistically significant clinical indexes reduction from baseline. More reduction was present in the test group for P.I. (14%±6) and for B.O.P. (18%±4) and was statistically significant (p less than 0.05). Within the limitations of this study, bacteriotherapy can be considered effective in reducing plaque and BOP in patients with controlled diabetes type II and gingivitis.

Abstract
TheraCal LC (TLC, Bisco Inc., Schaumburg, IL, USA) is a light-cured, resin-modified, calcium silicate-filled base/liner material designed for direct and indirect pulp-capping. In this study the result of the evaluation in vitro of the biocompatibility and chemical-physical properties of TLC are reported. TLC specimens were prepared under aseptic conditions in strict compliance with the manufacturers instructions and sterilized. Osteoblast-like cells (MG63) were used. For different time points, solubility, water uptake, alkalinizing activity and cytotoxicity were evaluated. In ddH20 and in DMEM+FBS, TLC showed a loss of material increasing simultaneously with the absorption capacity. The increase of water uptake of the material promoting the solubilization of mineral ions in medium is a requisite for a bioactive material. The alkalinizing activity is correlated to antimicrobial/bacteriostatic activity and to the ability to favor the formation of apatite deposits. The pH values for water absorption after immersion of the disks ranged between 8 and 9 at each times of evaluation. Cytotoxicity was not observed in MG63 cells treated with TLC and after 5 days, the cells were organized to form a confluent monolayer as demonstrated by fluorescence microscopy observation. TLC showed biocompatibility on MG63 cells allowing a physiologic cell growth and differentiation. The chemical-physical properties and biocompatibility of TLC observed in vitro in the present study, allows considering this cement as an innovative pulp-capping material for the vital pulp therapy.

Abstract
Osteocartilagineous differentiation within malignant melanoma is a rare occurrence with several implications for diagnosis. Most of the reported cases have occurred in acral lentiginous malignant melanomas. In this paper, the authors describe the clinical, morphological, immunohistochemical features and surgical treatment of a case of primary oral mucosal melanoma with osteocartilaginous differentiation and they review the existing literature. The clinical history of a 67-year-old man affected of oral malignant melanoma was described from the first presentation to the second recurrence. FISH analysis on primary lesion and on relapses showed positive results both in epithelioid and in osteocondroblastic areas. Because of the scarcity of literature in osteogenic melanoma, histological identification may be problematic and prognostic factors and therapeutic protocols are nor well established. Immunohistochemical and molecular techniques can help to diagnosis this rare lesion.

Abstract
The nose is a critically important aesthetic and functional portion of the face. We can explore nasal defects following trauma or tumor resections. Reconstructive techniques based on primary closure, skin graft, local flap, regional flap and microvascular free tissue transfer provides an algorithmic framework applicable to any reconstructive problem. From 2010 to 2016, 33 patients were treated with nasal reconstruction. Malignant tumor resection was the main cause of nasal defect. The most common tumor resected was BCC (basal cell carcinoma) followed by SCC (squamous cell carcinoma). Recurrence of malignant tumor were also treated. As described in the literature, we used the most common reconstructive techniques to handle post-resection defects. Most of the defects involved the dorsum and the ala of the nose, only rarely had the skeleton been affected by the resection. When the cartilage had been sacrificed, a graft from the septum or from the ear flap was harvested. All patients resulted in optimal reconstruction. In any case, a second surgery was needed. All the surgical procedures were performed in one single stage except for the paramedian forehead flap that required a second stage for division and inset of the flap. All donor sites did not show functional and aesthetic damage. All patients resulted in a morpho-functional restoration of the area affected by the resection with a high success rate. Following the algorithm when restoring the anatomical subunit is the base purpose has determined satisfactory results.

Abstract
The use of minimally invasive surgical techniques undoubtedly represents a huge advantage for both the clinician and the patient. This case report shows the possibility of making an implant-prosthetic rehabilitation in an upper jaw in a patient who presented dental elements 1.3 and 2.3 in bone inclusion. The use of computer-guided surgery offers us the possibility to carry out this type of implant rehabilitation without performing the extraction of the above-mentioned dental elements combined with the bone regeneration of the extraction sockets. Consequently, surgery invasiveness and post-surgery complications are reduced to a minimum. Additionally, the predictability of the methodology is evaluated with specific software that enables a comparison between what is virtually planned and what occurs in clinical practice.

Abstract
Alzheimers disease (AD) is a very common cause of dementia in developed countries and increases its prevalence progressively with age. AD etiopathogenesis is not yet understood. However, it is recognized that neuroinflammation plays a key role in its pathogenesis with the activation of microglia and the secretion of proinflammatory cytokines triggering irreversible neurodegenerative deterioration. This paper is a short review of the relationship between AD and periodontal disease (PD). Both processes may have common causes: both are inflammatory diseases and the prevalence and progression increases with ageing. However, we must consider that AD begins to develop many years before its clinical diagnosis. It is thought that in this prodromal period a connection could be established between both processes, both sustained by low intensity inflammation. There are several studies that relate both processes such as the possible systemic exposure to certain periodontopathogenic bacteria or the proinflammatory cytokines and other elements. It is argued that there are no modifiable factors such as age, or genetic factors, but that there are other factors that could be avoided, modified or controlled such as periodontal peripheral inflammation.

Abstract
Osseointegrated implants are very popular dental treatments today in the world. In osseointegrated implants, the occlusal forces are transmitted from prosthesis through an abutment to a dental implant. The abutment is connected to the implant by mean of a screw. A screw is the most used mean for connecting an implant to an abutment. Frequently the screws break and are lost. There is an alternative to screw retained abutment systems: the cone-morse connection (CMC). The CMC, thanks to the absence of the abutment screw, guarantees no micro-gaps, no micro-movements, and a reduction of bacterial leakage between implant and abutment. As P. gingivalis and T. forsythia penetration might have clinical relevance, it was the purpose of this investigation to evaluate molecular leakage of these two bacteria in a new CMC implants systems (Leone Spa®, Florence, Italy). To identify the capability of the implant to protect the internal space from the external environment, the passage of genetically modified Escherichia coli across implant-abutment interface was evaluated. Four cone-morse Leone implants (Leone® Spa, Florence, Italy) were immerged in a bacterial culture for 24 h and bacteria amount was then measured inside implant-abutment interface with Real-time PCR. Bacteria were detected inside all studied implants, with a median percentage of 3% for P. gingivalis and 4% for T. forsythia. Cone-morse connection implant system has very low bacterial leakage percentage and is similar to one-piece implants.

Abstract
Among all different types of cutaneous scleroderma, Parry Romberg syndrome and linear scleroderma “en coup de sabre” typically involve the visage. Gradual degeneration of the tissues, from the skin up to the bone, is the stigmata of the diseases and the range of clinical manifestations is wide. They typically start during childhood and slowly progress before stabilizing. Considering the gravity of the associated deformity and its impact on facial function and appearance, we strongly advocate a prompt intervention that however must be tailored on paediatric patients. There is not a general consensus on hemifacial atrophy treatment, but autologous fat grafting has been proved to be a suitable technique, due to its low morbidity, repeatability and efficacy in correcting volume defects and in improving skin texture. Following the same concept of safeness and non-invasiveness we propose 3D stereophotogrammetric acquisitions as a possible tool for the pre- and post-surgical follow up, indispensable to evaluate the surgical results. We present our case series composed of 8 paediatric patients, aged between 11 and 17 years, who underwent several lipofilling procedures, from 2012 to 2016. Starting from 2015, 3D stereophotgrammetric data has been obtained.

Abstract
A study was made of the correlation between the serum and salivary glucose levels in healthy subjects and in patients with type 2 diabetes, in order to establish the validity of salivary glucose determination in monitoring glycemia. Ninety-seven subjects were included in the study: 47 diabetic patients and 46 controls, aged between 40- and 80-years-of-age. Venous blood and saliva samples were collected in both groups under fasting conditions and after administering a test meal (15% proteins, 55% carbohydrates and 30% lipids). The glucose levels were measured using the glucose oxidase technique. The salivary glucose levels were seen to be greater in the diabetic group vs the controls both under fasting conditions (baseline) and after the meal (postprandial) (p=0.023 and p=0.008, respectively). A significant positive correlation was found between the serum and salivary glucose levels at baseline and under resting conditions, particularly in the diabetic group (r=0.389, p=0.002). The coefficient of determination of the simple linear regression model was R2=0.042, showing salivary glucose to be related to the blood glucose levels. In conclusion, salivary glucose concentration is correlated to serum glucose, particularly in type 2 diabetics.

Abstract
To correct skin imperfections, aesthetic medicine today makes use of injectable dermal fillers that allow filling skin by increasing the volume of soft tissue. Currently, there are many fillers usable for their excellent biocompatibility and low allergic reactions that ensure good results and good compliance. Among these, the most widely used filler is Human Plasma, obtained by centrifugation from patient blood and processed through cycles of centrifugation and heating, until it becomes a gel. In this work, we evaluated the effect of the Plasma on fibroblasts behavior in terms of cell viability, survival, growth and collagen production. To this aim, the expression levels of some adhesion and traction-resistance related genes (COL11A1, ELN, GDF6, IGF1, DSP, ELANE, HAS1, HYAL1, COL1A1 and COL3A1) were analyzed using real time Reverse Transcription-Polymerase Chain Reaction (real time RT-PCR). All genes, except for COL1A1, COL3A1 and COL11A1, were up-regulated after 24 h of treatment. Altogether, our results point out the good potential of Plasma. In particular, we appreciated an up-regulation in some of the most important genes involved in bio-revitalization, such as elastin and hyaluronic acid.

Abstract
BACKGROUND We present a series of 10 patients with osteonecrosis of the jaws (ONJ) that appeared following cancer chemotherapy. MATERIAL AND METHODS Of the 10 cases with ONJ, six had bone metastases from breast cancers and the other four had multiple myeloma. We analysed the location of bone metastases, as well as the characteristics of the ONJ, and the drugs with which they had been treated for their bone metastases. RESULTS Of the 10 patients, all had ONJ in the mandible; 50% also had maxillary involvement. The average number of areas of painful exposed was 2.1 per patient (range 1-5). In seven patients a tooth extraction preceded the onset of ONJ. Two patients developed oroantral communications and another a cutaneous fistula to the neck with suppuration. In all the 10 patients the histopatholological diagnosis was of chronic osteomyelitis without evidence of metastatic disease to the jaws. All the patients had received treatment for their malignant bone disease with bisphosphonates. These were the only drugs that all patients had received. CONCLUSION ONJ appears to have a relationship with the use of bisphosphonates.

Abstract
OBJECTIVE To study the prevalence of oral lesions in 35 patients diagnosed with generalized recessive dystrophic epidermolysis bullosa (RDEBg), with a quantification of their microstomia in comparison with a control group. MATERIAL AND METHODS The presence of oral mucosal lesions and interincisal maximum oral aperture (MOA) was determined, classifying microstomia according to the method of Naylor, Douglass and Mix (1984). RESULTS Blister lesions were identified in 92% of the patients at the time of exploration--the tongue being the most affected location. Microstomia and palatal atrophy were the most prevalent sequelae (100%), while ankyloglossia, vestibular obliteration and lingual depapillation were recorded in over 90%. In 80% of the patients interincisal MOA was <30 mm (severe microstomia), while in the remaining cases maximum aperture was in the range of 31-40 mm (moderate microstomia). CONCLUSIONS Blister lesions were found throughout the oral mucosa in our series of patients with RDEBg, the most frequently affected location being the tongue. These lesions in turn led to invalidating sequelae such as microstomia and ankyloglossia.

Abstract
Ischemic heart disease is the most common cause of death in developed countries. The classical protocols for providing dental care in these patients with chest angina or myocardial infarction were based on the classification of the American Society of Anesthesiologists (ASA), postponing therapy for a minimum of 6 months after infarction in order to ensure safer dental treatment. However, advances in diagnostic techniques and medical and surgical treatments in patients with heart disease have led to the development of more precise risk assessment protocols, thus allowing earlier post-infarction dental treatments and oral surgery, with acceptable safety margins.

Abstract
INTRODUCTION Vasoconstrictors associated to local anesthetics habitually used in dental practice have been reported to influence arterial pressure, in the same way as other factors such as patient anxiety or stress. OBJECTIVES The present study investigates the variations in systolic and diastolic arterial pressure in three groups of patients subjected to conventional dental treatment in the form of molar extraction, with the aim of determining whether such variations are attributable to the use of a vasoconstrictor or to other factors such as patient anxiety. MATERIALS AND METHODS A total of 43 healthy males with normal blood pressure readings were grouped according to the type of anesthetic solution employed: Group I (2% lidocaine with epinephrine 1:80,000), Group 2 (3% mepivacaine with epinephrine 1:100,000) and Group 3 (3% mepivacaine with no associated vasoconstrictor). In all cases the Hamilton Anxiety Scale was applied, with blood pressure recordings before and after anesthetic injection, during dental extraction, and at the end of treatment. RESULTS No statistically significant differences were observed in the blood pressure variations among the groups according to whether or not a vasoconstrictor was associated to the anesthetic solution in these healthy subjects. In increased systolic pressure was observed during extraction in all three study groups. CONCLUSION Our findings suggest that the use of a vasoconstrictor in association to the local anesthetic solution does not substantially modify blood pressure. On the other hand, the observed increase in systolic pressure in all three treatment groups may be attributed to patient anxiety.

Abstract
We present 3 patients who had episodes of orofacial pain compatible with cluster headache, the differential diagnosis being established with pulp pain of dental origin. Cocaine inhalation triggered pain in the premolar zone of the upper jaw, followed by spread of pain to the periorbital region on the same side. The pain episodes were very intense and lasted between 30 and 120 minutes. The patients presented conjunctival injection and lacrimation of the affected eye during these episodes. The crises were always unilateral. In one patient, pain shifted sides from one crisis to another within the same symptomatic or cluster period, affecting the side through which the drug was inhaled. Pain usually appeared 1 to 2 hours after cocaine consumption, though it disappeared 5 to 10 minutes after again inhaling the drug. None of our patients acknowledged cocaine consumption at the first visit; drug inhalation was only admitted at subsequent visits, once a degree of confidence had been established with the physician.

Abstract
The strong relationship between the pineal gland and the immune system continues to establish itself more and more. In situations of a pinealectomy or in those of inhibition of the production of melatonin, a state of immunosuppression is produced which disappears when the patient receives this hormone. Likewise, melatonin counteracts the negative effects that immunosuppressive drug treatment produce over the immunity. It is due to these facts that one postulates the possibility of utilizing melatonin in primary and secondary immunodeficiency states as well as in cancerous immunotherapy. The action of this hormone over the immune system is carried out through the T-helper lymphocytes, lymphokines and also it seems through certain pituitary hormones. On the other hand, lymphokines such as gamma-interferon and interleukin-2, as well as the thymus, can modulate the synthesis of melatonin at the level of the pineal gland. Without doubt, all these actions have important consequences at the time of treatment of our high-risk dental patients who have, in one way or another, an altered immunologic system. The altered immune system has direct implications in primary oral pathologies, or in others derived directly from our dental treatment.

Abstract
Forty-nine patients with burning mouth syndrome were simultaneously evaluated through a psychiatric interview and a psychopathologic questionnaire (SCL-90). The same protocol was applied to a control group (n = 47) free of oral complaints and with a similar age and sex distribution. The subgroup with burning mouth syndrome and associated psychiatric disorders differed from the subgroup of patients without psychiatric disorders in that the former exhibited significantly more symptoms of anxiety, depression, obsession, somatization, and hostility. This latter parameter appears to be present particularly among depressed persons. No significant psychopathologic differences were observed between the subgroup with BMS who exhibited no psychiatric disorders and the controls who were free of oral disorders.

Abstract
Seventy-four patients with burning mouth syndrome underwent a psychiatric interview; Hamilton's Depression and Anxiety Scales were applied independently. A psychiatric diagnosis was established in 38 cases (51.35%). Depression was the predominant disorder. The evaluation scales showed that when present, anxiety greatly influences the psychiatric condition of these patients. The differences in the results obtained with the two methods are discussed.

Abstract
We studied the clinical characteristics of 93 patients with recurrent aphthous stomatitis (RAS); 66 corresponded to minor aphthae (MiRAS), 20 to major aphthae (MaRAS), and 7 to herpes-like ulcerations (HU). MiRAS was seen to present the lowest rate of recurrences, as well as the shortest duration and the fewest lesions per episode. In turn, MaRAS presented the longest duration per recurrence, along with a number of lesions and recurrences that was lower than in HU but greater than in cases of MiRAS. Finally, HU developed the greatest number of lesions and recurrences. When we classified RAS according to the rate of episodes, no statistically significant differences were observed among the three types in terms of patient age, number and duration of lesions, or evolution time of the oral disorder.

Abstract
We studied 66 heroin-addicted patients from Valencia Community, comparing them with a control group of 30 healthy subjects. In all cases the CAO index and gingival state were analysed, including possible pathology of oral mucous. It was revealed that the major oral deterioration was in the experimental group. This was directly related to oral hygiene deficiency, which was brought about in the period of active addiction. At the same time the difference in oral mucous pathology between the two groups was not significant.

Abstract
Seven patients with lichen planus of the oral mucosa (four with erosive and three with reticular types of the disease) were studied; they were treated with 500 mg of griseofulvin twice daily for 2 1/2 months. In no case was improvement observed; on the contrary, in four patients (two with erosive and two with reticular forms) the condition worsened.
