The lesions did not respond to conventional periodontal treatment. The clinical appearance was consistent - with vesiculo-bullous conditions, such as Pemphigus Vulgaris and Mucous Membrane Pemphigoid. These conditions have an auto- immune etiology, whereby pathologic auto-antibodies are generated against structures that constitute the epithelial cell-cell or cell-connective tissue attachment systems. Accurate diagnosis is mandatory due to the high risk, at least in part of them, to spread to extra- oral sites, such skin, eyes and other types of mucosae and cause severe morbidity and even death. Diagnosis is based on routine biopsy aimed to identify the characteristic histomorphological features and on direct immunofluorescence that highlights the type and pattern of the deposition of the auto-antibodies with the affected tissue. The present biopsy did not show features of a vesiculo-bullous condition. However, the presence of a foreign material in the form of fine granules was highlighted by polarized microscopy. Immunofluorescence revealed a %pattern of auto-antibodies that was supportive of Mucous Membrane Pemphigoid. In lack of involvement of any other oral site, the patient has been treated with local agents, as commonly accepted. The present case emphasizes the need to consult specialists from various disciplines, especially in those cases where the clinical response to a common practice is not as expected.

The reconstruction of atrophic alveolar ridges using autologous Onlay Bone Grafting (AOBG) was originally reported in 1975. It's still considered as the 'gold standard' bone-grafting material, as if combines all properties required in a bone graft material; osteogenesis, osteoinduction, and osteoconduction. The use of intraoral donor sites, such as the mandibular symphysis, and ramus, offers no cutaneous scarring, minimal discomfort, and less morbidity compared with the extraoral sources. In addition, intraoral sites comprises good bone quality, convenient surgical access, good incorporation with a short healing time, high biocompatibility and embryological proximity. Furthermore, recent studies describe extensive bone deficiency reconstruction using solely intraoral block bone grafts by means of the multities technique, possibly by re-harvesting bone from the same donor site. the anatomic configuration in the atrophic site, influences the surgical choices, i.e. when surgical reconstruction is performed in the anterior atrophic maxilla, the reference standard of care would be to perform subnasal augmentation procedure for vertical augmentation with additional vertical and/or horizontal AOBG augmentation if necessary. For the AOBG to be accepted in the augmented area, other elements are introduced for support and rehabilitation; Growth Factor (GFs) for example, are expressed during different phases of tissue healing and are therefore a key element in promoting tissue regeneration. Platelet Rich Plasma (PRP) is an inexpensive way to obtain many GFs in physiological proportion and therefore has gained wide interest as a therapy for both soft and hard tissue injuries. In addition, Platelet-Poor Plasma (PPP) is composed of acellular plasma containing fibrinogen and growth factors, and is used as a \"biological membrane\" to cover the entire augmented area and donor sites that were filled with bone substitutes saturated in PRP or BMAC (Bone Marrow Aspirate Concentrate)as scaffold. Mesenchymal stem cells (originated from the BMAC) can be differentiated into diverse tissues, including bones. It has been suggested that transplantation of autologous stem cells from bone marrow can as well enhance bone healing. Patient satisfaction is a key factor in the success of implant therapy, especially in the anterior maxilla. Defect in the gingival continuity of shape cannot be always compensated by the quality of the dental restoration only. The challenge is that hard and soft tissue augmentation is necessary to achieve a successful result. The challenge is that hard and soft tissue augmentation is necessary to achieve a successful result. The aesthetics of the patient can be improved using sub-epithelial connective tissue graft.

Data were collected from dental school records, followed by an online questionnaire Results: Between 2001 and 2013, 268 out of 925 students left and did not return the following year, reflecting a dropout rate of 29%. A total 98 dropouts responded to the survey. The academic achievements of the dropouts were higher than average. The primary reason for quitting dental school was attraction to a different professional field (70%) and lack of interest in dentistry (11%). Almost all the dropouts left in the first three years: 80% of them transferred to medical school, 17% transferred to a profession other than medicine, and 4% continued their dental studies in another institution. Conclusion: Dropout was clearly not due to academic reasons, but rather attributable to pursuit of medical studies. The present findings imply that the admission process failed to identify students who do not intend to graduate.
