Mucocele is a common lesion of the oral mucosa that results from an alteration of minor salivary glands due to a mucous accumulation. Mucocele involves mucin accumulation causing limited swelling. Two histological types exist -extravasation and retention. Mucoceles can appear at any site of the oral mucosa where minor salivary glands are present. Diagnosis is principally clinical; therefore, the anamnesis should be carried out correctly, looking for previous trauma. The most common location of the extravasation mucocele is the lower lip, while retention mucoceles can be found at any other site. Mucoceles can affect the general population, but most commonly young patients (20-30 years old). Clinically they consist of a soft, bluish and transparent cystic swelling which normally resolves spontaneously. Treatment frequently involves surgical removal. Never-theless micro marsupialization, cryosurgery, steroid injections and CO2 laser are also described. Mucocele is a common lesion and affects the general population. For this reason we felt it would be interesting review the clinical characteristics of mucoceles, and their treatment and evolution in order to aid decision-making in daily clinical practice.

Introduction: Oral bisphosphonates (BFFs) are frequently used in the treatment of progressive systemic pathologies such as osteoporosis or Paget's disease. They are the first choice due to their ability to inhibit osteoclast activity, prevent resorption and modulate bone turnover rate. The plethora of clinical studies that analyses multiple variables to estimate the feasibility of dental implants between users oral BBF, agree that the failure rate is minimal, and generally there are multiple elements, classified into four categories: bacterial factors, factors biomechanical, psychological factors and systemic factors. Its late effects include pain, swelling, paresthesia, discharge, ulcers, fistulas, periodontal pockets, tooth loss, radiolucent osteolytic lesions, among others. Case report: We documented an exceptional case of the loss of two dental implants osseointegrated and charged rightly, 15 years ago in a 66 years-old patient with osteoporosis who has been taking ibandronic acid orally once a month for the last eight years. Conclusion: The clinician must cover all preventive and interceptive aspects prior to dental implant treatment in order to prevent failure thereof, despite being low incidence among users of bisphosphonates.

Background: In recent years the use of orthopantomography has been proposed as a low-cost, reliable and noninvasive diagnostic medium for detecting atheromatous plaque. The purpose of this study was to correlate the presence of carotid calcifications (atheroma) in orthopantomographs with specific risk factors for cerebrovascular accidents (previous cerebrovascular accidents, arterial hypertension, and diabetes). Patient and Methods: The methods used in this observational study of cases and control subjects followed STROBE (Strengthening the Reporting of Observational studies in Epidemiology) recommendations. The study analyzed a total of 1,602 panoramic radiographs taken for dental diagnostic purposes between January 2010 and February 2014. The main variables analyzed were the incidence of atheromatous plaque and other cardiovascular risk factors. Epidat 3.1 statistical software was used to determine minimum sample sizes and the results were analyzed using PASW (Predictive Analytics Software) Statistics 10.0.0. Results: For all the variables analyzed, the correlation between radiographic detection of atheromatous plaque and the presence of cardiovascular disease risk factors was found to be statistically significant (RR>1.5). Conclusions: The presence of cardiovascular risk factors is related to the incidence of radiopaque lesions at the carotid artery bifurcation, indicating the presence of atheromatous plaque.

S25The patient carried out posterior follow ups showing a positive healing of the bone around the surgical area. Conclusions: radiographic exploration of non erupted third molars is crucial for the early diagnosis of possible pericoronal cystic pathology associated. Objectives: Review the indications, surgical problems, complications and results related to the placement of zygomatic implants in elderly patients and anatomical changes associated with age. Material and method: A literature review of the literature of the last 10 years consulting sources in medline via pubmed database. Selecting interesting articles that respond to key words: ¨elder zigomatic implants¨. Results: The success of zygomatic implants does not decrease with age, conserving a survival rate above 95%. the negative points of other treatment options are avoided such as donor site morbidity in bone grafts in compromised health patients. However this technique also has risks. The prosthetic part allows functional, aesthetics and soft tissues rehabilitation, in less time for the patient. There are anatomical age-related changes in the maxilla and the zygomatic bone, which affect the placement of these implants. Conclusions: Zygomatic implants are a recommended but complicated treatment option for the geriatric population in cases of large maxillary atrophy when treatment options by conventional implants are not posible. Primary Sjögren`s syndrome (pSS) is a systemic chronic autoinmune disease that is characterized by lynphocytic infiltration of the exocrine glands, which causes dry mucosas, especially mouth and eyes's. SSp prevalence in >70 years patients is 15% and for its diagnosis it's used two main tests: salivary glands scintigraphy (gS) and minor salivary glands biopsy (gB). Objectives: 1) To report senile onset pSS prevalence in some patients with sicca complaints 2) To describe diagnostic validity of gS and/or gB in sPSS patients 3) To describe affectation patterns in salivary gland scintigraphy. Patients and Methods: Retrospective observational study of >60 years patients with xerostomia and/or recurrent mayor salivary glands swelling referred for pSS screening in 2006-2012 Results: 57 patients (52 W), mean age 73.3 years + 5.7. Recurrent gland swelling 12.3%; associated comorbidity 75% and with xerostomia causal drugs 42%. Altered scan gS findings: 58% patients, 52% uptake predominantly vs 9% washout and 26% submandibular location. gB was performed in 18 patients: normal 72%; non-specific alterations 21%; focal sialoadenitis 7%. It was diagnosed sPSS in 17 (29.8%), of which just 17.6% had focal sialoadenitis and 23% non-specific alterations. 32% of non-sPSS patients presented non-specific alterations. Conclusions: 1) 30% patients >60 years with sicca complaint were diagnosed sPSS 2) gS showed salivary function impairment in 58% patients, 3) gS alteration in uptake and submandibular predominance were the most commonly findings in sPSS. 3) 17.6% sPSS patients had focal sialoadenitis and bG was normal in 59%. -Oral Presentation
