Long-term success of prosthetic dental implants treatments is provide by both of surgical time of implant insertion and the proper prosthetic treatment itself (implants "loading"). For this it is necessary to know the risk factors involved in such work, and the adjustment of clinical prosthetic case according to their occurence. The treatment plan will include ways to reduce stress tensions appering at prosthetic implant complex and the minimize their effects both in short and long term. [ABSTRACT FROM AUTHOR]

Adhesion of dental materials to the dental hard tissue is dependent on a number of factors relating both to the material used and the type of approach to dental substrate. The purpose of this study was to demonstrate that the size of the hybrid layer (HL) in the cavity by class II prepared mechanic (M) and kinetic (K) with laser, evaluated by scanning electron microscopy (SEM) restored with giomer (PRG-Prereacted Glass-Ionomer) Beautiful (Shofu) is different. Method: The study was realized in vitro on a sample of 20 human teeth premolar and molars extracted for orthodontic or periodontal reasons. Permission was obtained from a institutional ethical committee of University of Medicine and Pharmacy Gr.T. Popa, Iasi, and that subjects gave written, informed consent. The teeth were divided at random into equal two groups (Gr). There have been Class II cavities with a depth of 2 mm with a width of 3 mm and height of 4 mm M at high and low speed with cylindrical diamond No.1 and globular carbide and K-LASER peaks MZ6-5, 5W+20 Hz, 30% water, 60% air. The teeth were restored using 3M™ Schotchbond Etch, Single Bond Dental Adhesive System 3MTM, giomer Beautiful (Shofu). Gr.1:(M) (n=10)-Beautiful(Shofu); Gr.2:(K)(n=10) Beautiful(Shofu). The materials were placed in a single layer and photo activated with source halogen (3M), term cycled 500cycles (50-550), stored (48h), cut lengthwise (diamond), polished, conditioned (H3PO4-37% -5s), analyzed by SEM (JEOLJSM 6390), SPSS 14.00 statistically analyzed (ANOVA, p ≤ 0.05). Results: Analysis of the HL has highlighted differences between groups only in the enamel p = .000 average size HL being Gr.1:8,68 (± 0.97)μm, Gr.2:5,99 (± 0.39)μm. Conclusions: Mean of size of HL made between giomer and dental hard tissue was influenced by the cavity preparation method in favor in samples prepared mechanically especially in the enamel.

The purpose of this paper is to present one of the many choices in prosthodontics treatments which concernes the direct reconstructions, using fiber-quartz reinforced endodontic posts and core systems. The method began to be used very often due to the biocompatibility, radioopacity, elasticity module very close to that of dentina, easy technique and fast to set (15-20 minutes), their combination with dualcure omposites permeeting an homogen mechanical and fizical-chemical reconstruction. They satisfy with succes the esthetical demands, permeeting the apliccation of integral- ceramic crowns. [ABSTRACT FROM AUTHOR]

Mesiodens is the most common supernumerary tooth. Mesiodens tends to run in families suggesting a genetic cause. Objectives: To describe clinical variability of mesiodens as observed in our cases; to analyze the pattern of inheritance in families. Methods: Investigation of mesiodens was carried out on 23 Caucasian patients ranging in age from 8 to 23 years; based on the shape, size and location of mesiodens we classifi ed the patients in three groups: normal size palatally erupted conical mesiodens, normal size well aligned erupted conical mesiodens and rudimentary mesiodens; the diagnosis of mesiodens has been made by oral and radiographic examinations; family study was also performed. Results: All patients have had normal primary dentition except for one case; patients presented mesiodens as an isolated trait or in association with other dental anomalies; the isolated form of mesiodens occurred familial; the affected members within the same family often exhibited variability in clinical presentation; positive family history of the patients suggested different modes of inheritance. Conclusions: Mesiodens is an inherited developmental abnormality that alters the number of teeth; intrafamilial variability observed could be explained by variable expressivity of a single gene or the effect of modifi er genes; interfamilial variability could be explained by locus heterogeneity. Early diagnosis of familial mesiodens minimizes the treatment required and prevents the associated clinical problems. [ABSTRACT FROM AUTHOR]

The study of bacteraemia after stomatologic interventions and oral surgery is difficult to do, requires minutia, technical accuracy and scientific rigorousness, because numerous clinical and laboratory data need to be corroborated: the oro-dental pathological variety, oral microbiocenosis complexity, low oral hygienical standard, dental procedures variety and quality of blood prelevations for hemoculture, quality and utilised laboratory techniques.

The present study comes with a detailed presentation of the causes that lead to the apparition of the chronic maxillary sinusitis of odontogenic origin and also with a presentation of the best way of treatment of this affection. For this study we selected a lot of 183 pacients, from a total of 8,695 who have been treated in our clinic during a period of 5 years. From an etiological point of view, the periapical septic processes (40.98), followed by the oroantral fistulae are the main factors responsible for the apparition of the maxillary sinusitis. The teeth most frequently involved into the apparition of the maxillary odontogenic sinusitis are the maxillary first molar followed by the maxillary second molar. The surgical treatment by mucosal stripping proved to be the elective treatment of the chronic maxillary sinusitis, the postoperative recurrence appeared only in three cases. [ABSTRACT FROM AUTHOR]

The management of patients receiving long-term oral anticoagulant therapy during dental procedures is a controversial issue. Continuation of anticoagulation exposes the patient to serious hemorrhage, whereas cessation of therapy increases the risk of thromboembolism. There is now considerable evidence that many patients can safely be managed without stopping or altering their oral anticoagulation. The consensus from reviews on the management of dental that patients taking oral anticoagulant, with International Normalised Ratio (INR) below 4.0 should continue oral anticoagulant therapy without dose adjustment.

The dental abfraction theory is studied in the last two decades based on finite element method (FEM) and photo elasticity methods. These techniques showed that the concentration of the resultant occlusion force as a stress in the cervical area of the tooth. Following the study through FEM, resulted that the maximum cervical tensions are influenced by: size of the forces applied in different areas of the crown and increase in intensity after the lacuna phenomenon of the package level.

Chronic apical periodontitis have a great importance in the framework of odontal pathology through its frequency and local and general complications that it may generate. Physiologic, functional or iatrogenic aggression over the pulpal tissue leads to the apparition of degenerative processes that may amplify until becoming pathologic, producing an acute or chronic pulpitis, simple gangrene or its complications in the periapical aria - acute and chronic apical periodontitis. Periapical lesions usually have a chronic evolution as a connective, epithelial or cystic granuloma, forms under which local reactionary proliferative processes of the connective tissue are accompanied by degenerative forms.

Aim: Examination of parodontal status in patients with partial removable dental prostheses in comparison with the patients with fixed prostheses or without. Material and method: 60 patients were clinically examined, divided in 3 groups: patients with partial removable dental prostheses, patients with fixed dental prostheses and patients without prostheses. Parodontal exam was made, the bleeding, plaque and gingival indices were determined and the insertion loss and dental mobility were measured. Results and discussions: A more important parodontal affection was observed in patients with partial removable dental prostheses in respect to the other groups. Maximum values of parodontal indexes appear at the abutmant teeth of partial removable dental prostheses, no metter if they are covered by fixed restaurations or not. Abutmant teeth present greater values of the parodontical indexes than the remaining teeth. Conclusions: Abutmant teeth of partial removable prostheses present more often parodontal affection than the rest of the teeth. Through a careful supervision and proper hygiene, the degradation of the prosthetic field can be prevented. [ABSTRACT FROM AUTHOR]

Juxtabulbar optical nevritis and orbitar cellulitis are frequently associated to oral affections and are found in many cases from Oradea Emergency County Clinical Hospital, Ophtalmological Department. Until today there is no statistics of these affections by possible causes, therefore we consider useful to study their frequency between years 2000-2006, eventualy to determine the disease source and to present specific therapies (ophtalmic and dental treatments).

The ubiquitous use of latex gloves and other latex products in healthcare has resulted in a parallel incease in larex-asoociated reactions. To provide for a safe environment for both oral healthcare providers and patients alike, clinicians must understand the basis for latex-related adverse reactions, recognize associated signs and symptoms, and initiate appropriate preventive and therapeutic strategies. The recommendations for preventing/minimizing latex allergy in the oral healthcare setting are based on current knowledge and a common sense approach to the problem. Evolving manufacturing technology and improvements in measurement methods for latex proteins may lead to changes in these recommendations in the future. [ABSTRACT FROM AUTHOR]

Deep, covered occlusion, being characterised by the increased occlusion and by the retro dentition of all superior incisors, can sometimes raise esthetic problems in elder patients who, because of various reasons, cannot undertake an orthodontic treatment adequate to the clinical situation. Oral reabilitation of the patients with this type of anomaly is applied only in certain clinical situations, having as purpose the reconstruction of the maxillary system, normalising the guides as much as possible.

Objective: The purpose of this study was to compare the accuracy of the working length determined by two methods: using exclusively an apex locator or using an apex locator associated to a radiological exam. Method: The study was made on 59 radicular canals, divited in 2 groups depending on the method used to determine the working length. For the first group (25 radicular canals) the working length was determined using just the apex locator. For the second group (34 canals) the working length determined by the apex locator was confirmed by the radiological exam. The distance between the canal obturation limit and the radiological apex was measured in millimeters for each canal and we calculated and registered the average. The registered data were statistically analyzed. Results: For the first group we obtained an average of 0,447 mm of the distance between the canal obturation limit and the radiological apex. For the second group the average was 0,368 mm, the average of the total number of necessary radiographies was 3,2. There were no significant differences between the 2 groups. Conclusions: The use of an apex locator to determine the working length is important in endodontics and this study indicates that there are no major differences for the canal obturations realized after the determinate working length between the two methods. A correct working length determination with a well-calibrated apex locator can avoid the necessity of radiological control during the endodontic treatment. This method can be used for patients that cannot be exposed to repeated radiation. [ABSTRACT FROM AUTHOR]

Objective: The objective is to emphasize the existence of some correlations between the age of the diabetes, the type of medication and the apparition of apical periodontitis after an endodontic treatment. Material and method: The study included patients suffering from type II diabetes mellitus and it was made over a two-year period, when we evaluated the periodontal status of the patients that had an endodontic treatment due to gangrene diagnose. Results: The registered data were statically analyzed. We followed the evolution of the endodontically treated teeth depending on the age of the diabetes and the type of anti-hyperglycemic treatment. Conclusions: The level of glycemic control has an influence on the evolution of the endodontic treatments, as the decrease of the metabolic control may determine a long period endodontic failure.

Because every person is different, they'r response to aggresion is diversified, generating unidentified pathologies as ‟The fatigue sindrom„, polyalergies, autoimmune disease. At the oral's cavity level the aggresion can form because of 3 tipes of alloy: mercury, chromium, nikel, ball, cadmium, titanium which can start gingival methalosis as well as the growth of concentracion of the metal in blood. To counteract this symthoms Prof.Sami Sandhaus replaced metals with zirconium, which proved to have real qulities of immunologic biocompatibility. [ABSTRACT FROM AUTHOR]

Introduction: Third molar morphology is very complex due to the variety of shapes and also to the number of roots and canals, which makes its treatment a real challenge and trial for the practitioner. Objectives: This study aims to analysing the internal radicular morphology of three molars, using a contrastive substance injected on the channel and the technique of teeth transparency. Materials and method: 38 teeth extracted on various reasons were studied after removing the dental pulp. An intracanalicular injection of a contrast substance (China ink) followed. The teeth were decalcified using nitric acid and were subsequently made transparent by using methil salicilate in order to point out aspects of internal radicular anatomy. Results: Third maxillary molars presented Ventucci types II and IV canals for mesio-vestibulary root, Ventucci I type canals for disto-vestibular and palatal roots. Intercanalicular communication was frequntly found at the level of the mesio root and lateral canals were found especially in the apical third. Conclusions: Knowledge of internal radicular morphology considerably improves the therapeutic vision leading to the suceess of endodontic treatment. [ABSTRACT FROM AUTHOR]
