A New System for Choosing the Form and Size of Complete Denture Anterior Teeth

Introduction: In the absence of pre-extraction records, the choice of the size an form of anterior complete denture teeth can be extremely subjective. Several clinical and statistical parameters are usually used for choosing the correct size and form of the complete denture anterior teeth. Clinical Innovation: The technique consists of a system that allows the dentist to choose and, if necessary, easily change the dental mold during maxillomandibular recording session. The unique feature of the system is that six teeth of each mold are represented by veneers, which are connected to each other on the lingual surface by a fiber that allows each veneer some degree of movement. Discussion: This…

LESIONI ORALI E CERVICALI ASSOCIATE A PAPILLOMA VIRUS UMANO

The aim of this review is to carry out a quick excursus on the epidemiological and clinical aspect of oral and cervical lesions induced by human papillomavirus (HPV) infection and on the way this virus is transmitted. HPV infection is transmitted above all through vaginal or anal sexual relations with partners carrying the virus. Also other types of sexual relations, such as oral sex, can be a vehicle of transmission, though much more rarely. In literature there is not enough data proving that oral-genital contact can really be a vehicle of transmission for human papillomavirus. It can be concluded, therefore, that evidences in further studies with a large sample group of patients who pract…

APPRAISAL AND PROMATION OF THE ORAL HEALTH IN A GROUP OF VISUALLY IMPAIRED PATIENTS

Transverse Asymmetries of the Maxilla Even in Healthy and Apparently Symmetrical Subjects

In the formulation of an orthodontic treatment plan, the three-dimensional analysis of the dental arches represents a fundamental moment for the evaluation of all the morphological parameters necessary in order to have a correct and complete diagnosis. In this regard, the study of the dental arches on the horizontal plane is sometimes neglected or not thorough enough. When evaluating the transverse dimensions of the dental upper arche, the presence of an asymmetry is frequently found, and it means that an hemiarch is larger than the other. Furthermore, any variation in one of the three planes of space always involves an alteration also on the other two planes in order to have compensation. …

Methods. The authors examined 28 subjects, of whom 14 (10 women and four men) had BMS and 14 (nine women and five men) were healthy control subjects. They performed videocapillaroscopic examination with a capillaroscope with a fiber-optic probe at a magnification of ×200, which allowed them to examine the morphological characteristics within the capillaroscopic area accurately. Results. The ca…

OSTEONECROSIS OF THE JAW: AN UNUSUAL CASE REPORT

Study of microcirculation in oral lichen planus by video-capillaroscopy.

Objective The aim of this study was to evaluate “in vivo” the oral microcirculatory characteristics in patients with oral lichen planus (OLP) and to discover any differences in microcirculation in comparison with healthy patients. Study design Twenty patients with established diagnosis of OLP and 20 healthy patients were examined in our laboratory by means of contact optical probe videocapillaroscopy. The examined areas for each patient were the right and the left buccal mucosae. Capillary density and total capillary diameter, as well as afferent and efferent loop diameter were studied; the discovery of characteristic (tortuous, branched) loops was also investigated. Results The results wer…

Modifications of interdental papilla microcirculation: A possible cause of periodontal disease in Hashimoto's thyroiditis?

Summary Background Hypothyroidism is defined by a decrease in thyroid hormone production and thyroid gland function. The aim of the present research has been to evaluate the morphologic interdental papilla microcirculation of patients suffering from Hashimoto thyroiditis (HT) and to evaluate a possible correlation with the associated periodontal disease. Methods Fifteen healthy subjects and 15 patients suffering from HT were examined. The patients who showed conditions known to compromise microcirculation, such as diabetes, hypertension and pharmacological treatments, were not included in the group of healthy patients. All patients were non-smokers. Gingival capillaroscopy was used to inves…

VASIDILATATION OF HUMAN GINGIVA AND NEUROGENIC INFLAMMATION

Plywood Jig—A New Technique for Root Canal Curvature Measurement

The successful outcome of endodontic treatment is dependent on complete cleaning, shaping as well as three dimensional obturation of the root canal system. A conventional radiograph is a two-dimensional replication of a three-dimensional object and does not provide any conclusive evidence for canal curvatures. An accurate knowledge of the tooth anatomy and curvature is essential to avoid procedural errors. 100 freshly extracted human teeth were used in this study. Digital images were obtained using the plywood JIG and Schneider’s technique. These images were analyzed using the VixWin Pro digital image analyzing software (Gendex system). Statistical analysis was done using paired t test. The…

Dentinal microcracks after root canal instrumentation using instruments manufactured with different NiTi alloys and the SAF system: A systematic review

Aim: The aim of this systematic analysis was to assess the prevalence of dentinal microcracks at various levels (3, 6, and 9 mm from the apex) after using instruments made with conventional, R-Phase, and M-Wire NiTi alloys and the SAF system. Materials and Methods: Electronic searches were conducted in the databases Embase, Cochrane Library, Scopus, PubMed, and Web of Science. To arrange search methods, “MeSH” terms and/or keywords typically associated with the subject were paired with the Boolean operators “AND” and “OR.” Additional searches were conducted on the websites of four separate endodontic journals. After reading the titles and excluding duplicates, 1000 of the 1343 documents ori…
