Full text linkAmelogenesis imperfecta(AI) is an inherited enamel dysplasia involving both dentitions with no other systemic effects. Here it is presented a case of a hypocalci ed enamel dysplasia(type III according to Wiktop classi cation) in a 21 year old male who was successfully treated with disilicate veneers and overlays
Oral Surgical Treatment of Patients With Chronic Liver Disease: Assessments of Bleeding and Its Relationship With Thrombocytopenia and Blood Coagulation Parameters
No full textPurpose Cirrhotic patients awaiting liver transplantation require eradication of infectious oral foci to prevent septic episodes after transplantation; however, cirrhosis can hinder hemostasis and can result in severe bleeding. The present study assessed the bleeding risk factors connected with the clinical history of these patients and the characteristics of the extractions. Materials and Methods We retrospectively analyzed 1183 extractions in 318 patients, including 47 with severe end-stage liver disease who were outside of our intention-to-treat bracket (ie, platelet count [PLT] >40 × 103/μL and international normalized ratio [INR] <2.5). Follow-up examinations included inspection of the oral cavity on the first, third, and seventh days, with reparatory surgery in the case of severe bleeding. Continuous variables were compared using the Mann-Whitney U and Kruskal-Wallis tests, and categorical variables were compared using Fisher's exact test. Binary logistic regression analysis was also performed. Results Within the intention-to-treat bracket, 1 of the 271 patients (0.4%) required surgical repair. The bleeding rate for an INR of 2.5 or more was significantly greater than that for a PLT of 40 × 103/μL or less (4 of 10 [40%] versus 2 of 34 [6%]; P = .02]. All 3 patients with both an INR of 2.5 or more and a PLT of 40 × 103/μL or less exhibited severe bleeding. No significant association between the occurrence of bleeding with either liver disease etiology or the number of molars extracted was found. No patient required hospitalization. Conclusions Patients with a PLT greater than 40 × 103/μL and an INR of less than 2.5 can be considered relatively low-risk patients. However, an INR of 2.5 or more and, to a minor degree, a PLT of 40 × 103/μL or less represent significant risk factors
La determinazione dei rapporti intermascellari sul piano orizzontale nel paziente edentulo
No full textLa corretta registrazione dei rapporti intermascellari orizzontali conferisce alla protesi la capacità di distribuire i
carichi masticatori su una superficie più ampia delle creste edentule, garantisce una masticazione efficace ed efficiente
e favorisce una migliore stabilità dei manufatti protesici. Poiché nel paziente edentulo viene meno qualsiasi
parametro intra-orale utile alla definizione dei rapporti intermascellari, è necessario ricorrere a parametri
anatomici e funzionali presenti in strutture extra-orali. La relazione centrica è una posizione limite e può essere
utilizzata come posizione di riferimento; il centro neuromuscolare è una posizione funzionale e può essere utilizzato
ai fini della riabilitazione protesica. Tra le tecniche per la determinazione dei rapporti intermascellari sono
da preferire i metodi non guidati. Tra questi, la deglutizione può essere utilizzata nella maggior parte dei casi; in
alcune condizioni cliniche (segni e sintomi di DCM, condizioni anatomo-funzionali sfavorevoli, ecc.) è necessario
utilizzare la tecnica del central bearing point
METODO RADIOMETRICO DI VALUTAZIONE IN VITRO DELLA QUANTITA' DI PLACCA BATTERICA ADESA AD UNA SUPERFICIE
No full textThe effect of glycine-powder airflow and hand instrumentation on peri-implant soft tissues: a split-mouth pilot study.
No full textFifteen edentulous patients with overdentures supported by two implants in the mandibular canine regions received periodontal therapy using both hand instrumentation with Teflon curettes and a glycine-based airflow system. Periodontal probing depth (PPD), bleeding on probing (BOP), and bacterial content (BC) within the gingival sulcus were analyzed. A significant effect modification of the glycine airflow with respect to time was found for PPD (P = .01), BOP (P < .001), and BC (P = .004), which were treated as ordered categorical variables. Glycine airflow may be more effective than Teflon curettes for the maintenance of periimplant soft tissues
The incidence of craniomandibular disorders in patients with cervical dysfunctions. A clinico-statistical assessment
No full textThe aim of this research was to measure the incidence of craniomandibular disorders in a group of patients with functional-type cervical alterations. The group consisted of 50 patients undergoing treatment for disorders of the cervical sectors of the spine. Each patient was subjected to a medical examination to investigate the presence of CMD signs or symptoms. From the data statistical analysis a higher percentage of cases with muscular and joint pain, limited mouth opening, deviation and deflection, were found in comparison with the percentage found among the general population. This demonstrates an overloading of the entire masticatory apparatus. Joint noise was less frequent, probably due to its exclusion from our sample of patients with arthrosis-type degenerative pathology
