Background The main goal of root coverage procedure is complete coverage of the recession defect with a good esthetic result related to the adjacent soft tissues and minimal probing depth after the healing process. Purpose The aim of this study was to compare the efficiency of surgical and nonsurgical treatment options in patients with gingival recession and dentin hypersensitivity (DH). Material and methods 60 patients with gingival recession Miller Class I and II with hypersensitivity and esthetic concerns were included. 30 of them were treated with free soft-tissue graft procedures and control group of 30 people were treated with anti-hypersensitivity gel. Surgically treated patients were separated in two groups: 20 of them- with coronally advanced flap with sub-epithelial connective tissue graft and 10 of them- with free gingival graft. Results We achieved full coverage on the exposed root surfaces in 18 patients treated with coronally advanced flap and de-epithelized graft and partial root coverage in two of them. Patients treated with free gingival graft procedure achieved full root coverage in 6 of them and partial on 4 of them (GR=1 mm after surgery). Surgical treatment led to resolution of the esthetic issues of the patients and elimination or reduction of the DH. In control group there were partial elimination of root sensitivity. Conclusion: In surgical treated group with both techniques we achieved resolution of DH and coverage of the root surface with healthy keratinized tissues. Surgery may be considered for treatment options of DH depending on the indications.

ABSTRACT:Because of its close anatomic relations with nosal and oral cavitis, the maxillary sinus is the place of most frequent inflammatory diseases of all paranasal sinuses.Introduction: The aim of this study was to establish differences in etiology and treatment of rhinogenic and odontogenic maxillary sinusitis.Materials and methods: In this study, we analyzed the etiology, clinical characteristics of the disease, x-ray findings, clinical course and treatment of 188 cases, which were diagnosed and treated as odontogenic or rhinogenic maxillary sinusitis in the Departments of Maxillofacial surgery and Otorhinolaringology -"St. Anna" Hospital, Sofia from 2005 to 2010. Patients were divided according to age and sex. Data was systematized and analyzed.Results: This study clearly showed that rhinogenic diseases of maxillary sinus are three times more frequent than odontogenic diseases. Also the etiology of odontogenic sinusitis most often is due to mistakes in the treatment of the upper teeth (alien corpuses, perforation after extraction), which is completely different from rhinogenic sinusitis. In the surgical treatment of rhinogenic maxillary sinusitis usually endonasal polypectomy was followed by operation according to Caldwell-Luc or functional sinus endoscopy. During the surgical treatment of odontogenic sinusitis the most frequent intervention was surgical plastic of oral-antral communication with mucogingival vestibular flap followed by operation according to Caldwell-Luck what is different from the treatment of rhinogenic sinusitis.Conclusion: Maxillary sinus often suffers from inflammatory diseases and should always be examined carefully by means of anamnesis, clinic exam and x-rays to identify its origin. Upper teeth should be treated carefully in everyday's dental practice to avoid being cause of sinusitis. Key words: Odontogenic Maxillary Sinusitis, Rhinogenic Maxillary Sinusitis PURPOSE:In the present study, we report our clinical investigations of cases of maxillary sinusitis caused by odontogenic and rhinogenic factors in order to establish the similarities and the differences in theirs etiology, diagnosis and treatment. METHODS:In our study we used the data gathered from the medical records of 188 patients whit maxillary sinusitis that underwent treatment (both surgical and conservative) in our clinic for the period of June 2005 to February 2010. Cases were divided according to several factors (diagnosis, etiology, underwent treatment, age, gender, etc.). RESULTS:Most of the patients treated in our clinic with maxillary sinusitis where directed to us either by their general practitioner or by their dentist. Very few of them sought medical help directly into the clinic.The common complaints for the odontogenic cases were oral symptoms such as swelling, pain and discomfort, and the formation of oroantral communication or fistula into maxillary sinus. The most common causative tooth was the first molar, followed by the second molar and the second bicuspid. We classified the causative factors of the d...

Regenerative medicine is based on advanced in research in biomaterials one of which is dentin autograft, which can have a major impact on the patient's treatment plan and for improving the quality of life. This review has been designed to investigate the effects of alveolar ridge preservation of alveolar bone with dentin autograft. The success of implant-supported restorations depends on the interaction between a number of anatomical, technical, surgical and prosthetic factors. Restorative-driven implant placement allows the optimal support of the surrounding soft and hard tissues and a satisfactory emergence profile of the final prosthesis. Ridge preservation is any procedure that takes place at the time of, or shortly after an extraction, prior or simultaneously with implant placement to minimise resorption of the ridge and maximise bone formation within the socket.Alveolar ridge preservation procedures with dentin autograft may decrease the need for further ridge augmentation during implant placement in comparison with u
