Clinical and histological study of a xenogenic bone substitute used as a filler in postextractive alveolus.

AIM: The development of oral implant techniques and the demand for the treatment of increasingly complex cases have drawn the attention of researchers and clinicians towards those systems and materials able to promote bone regeneration. The aim of this paper is to evaluate the clinical behavior and in particular the resorption times of the material used as a filler in postextractive alveolus with the intent of preserving the ridge volume, a prerequisite for successive insertion of osteointegrated fixtures. METHODS: A group of 12 patients, aged between 30-40 years, have been selected at the Oral Surgery Unit of the San Giovanni Calibita Hospital in Rome. They all required an endosseous implant following the loss of a dental element due to radicular fracture of periodontal pathology. The grafting material used is OsteoBiol Putty, an antigen-free bone paste composed of 80% granulated mix and 20% pure collagen. RESULTS: The results emerging from the histological analysis show that 3 months after insertion of this osteoconductive material in the receiving site it can no longer be detected in the samples collected and it has been completely substituted by trabecular bone tissue. CONCLUSIONS: The conclusion is drawn that the heterologous material used in this study shows excellent manageability allowing the operator to easily and accurately remove and shape it in the receiving site.

Bilateral anesthesia into Spix's spine. Ten years' experience.

AIM: This study examines 10.112 cases in 10 years of bilateral block anaesthesia to Spix's spine. The aim of this study is therefore to eliminate any doubt about executing a bilateral anaesthesia to Spix's spine for the extraction, in inclusion and impacted of the inferior wisdom teeth. METHODS: A retrospective study was carried out on 10,112 operations (59% females, 41% males,) regarding the removal of the lower 3 molar teeth undertaken in the past 10 years. Locoregional anaesthesia and standard instruments and protocol were applied to all operations. The anaesthetic used was mepicavina at 2% with epinefrine 1:100,000 with a 4 x 25 mm, 27 Gauge needle. In order to completely anaesthetize the areas subject to surgery a quantity of approximately 3-ml on each side was injected. Local anaesthetics used were the same throughout the study; all the patients were in good health and not undergoing any pharmaceutical treatment. RESULTS: The onset of complications was 3 times less when using local anaesthesia (LA) compared to general anaesthesia (GA). It was also proven that local anaesthesia was advantageous, as the operation time was considerably less (24 min for LA and 46 min for GA). CONCLUSIONS: The paper shows that LA offers a significant reduction in complications, psychological advantages for the patients and facilitation of the operational position too, so that GA is to be preferred only for non-cooperative patients.

[Impacted third molars and facial typology].

BACKGROUND: The increasingly frequent removal of asymptomatic or pathology free lower third molars raises several questions. In this paper, the relationships between inclusion of impacted third molars and facial typology, in studied in order to have a further evaluation parameter for their removal. METHODS: The study was carried out an 50 cephalometric radiographs. The patients, 25 males and 25 females, have been submitted to surgical treatment at our oral Surgery Department to remove the lower impacted third molarst. RESULTS: Among patients admitted for impacted third molars removal there was a larger percentage of brachyfacial (84% of the males, 71% of the females) in comparison with normofacial (8% of the males, 19% of the females) and dolichofacial (8% of the males, 10% of the females). CONCLUSIONS: The facial type, characterised by a shortened vertical dimension of the lower third of the face and an anticlockwise mandibular growth, presents a greater risk of included wisdom teeth.

Supernumerary teeth diagnosis and treatment approach. Six case reports.

Supernumerary teeth are relatively common in the general population, affecting the primary and the permanent dentition and have been reported in many genetic syndromes. They are classified according to form and shape. Seven different examples of hyperodontia are presented to highlight the numerical and morphological variation in dental abnormalities manifestations, empathising the importance of thorough clinical and radiological examination and of a correct therapeutic approach. The patients presented single or multiple hyperodontia, with particular interest for a 12 supernumerary teeth case. The clinical problems linked to supernumerary teeth were: impaction or ectopic eruption, crowding, possible root resorption of adjacent teeth. The therapeutical approach of supernumerary teeth varied on the position of the element in excess and on the complexity of the clinical case. In some cases the single extraction of the supernumerary tooth was indicated, while in other cases the extraction of the tooth was needed in addition to orthodontic treatment to gain sufficient space for the tooth with delayed eruption.

Seroprevalence of hepatitis A virus and Helicobacter pylori infections in the general population of a developed European country (the San Marino study): evidence for similar pattern of spread.

OBJECTIVE: To evaluate the role of faecal-oral transmission in the spread of Helicobacter pylori. DESIGN: A cross-sectional comparison of the patterns of hepatitis A and H. pylori seropositivity. METHODS: At interview, blood samples and questionnaire data were collected from a random sample of 1528 healthy subjects aged 20-85 years from the Republic of San Marino. Serum samples from each subject were then tested for anti-H. pylori and anti-hepatitis A antibodies. RESULTS: Overall, 529 of 670 H. pylori-seropositive subjects (78.9%) and 460 of 858 H. pylori-seronegative subjects (53.6%) were hepatitis A seropositive (P<0.01; odds ratio=3.2; confidence interval 95%=2.6-4.1). This association remained after adjustment by a multiple logistic regression analysis for the confounding effect of age and length of schooling, as surrogate for socio-economic status (OR=2.0; CI 95%=1.3-3.3). The age-specific prevalence curves for H. pylori and hepatitis A infections showed a parallel increase by age, although to a lesser extent for H. pylori. CONCLUSION: These findings provide evidence that in the community studied H. pylori may have spread in a manner similar to that of hepatitis A.

[Wall elasticity of the ascending aorta in ischemic heart disease].

M-mode echocardiography was used to examine in male subjects the physical properties of the ascending aorta, 3 cm above the valvular plane. Subjects were divided into three groups based on age, lifestyle and presence or absence of vascular disease: Group A (10 recruited military young men, age 20.87 +/- 0.834 years) in good health; Group B (14 senior competitive athletes, age 49.92 +/- 8.17 years); Group C (10 patients with effort-angina, age 53.1 +/- 11.18 years). We observed that: the inner diastolic diameter of the ascending aorta was different between Group A and B (p < 0.001) and between Group A and C (p < 0.001), and it increased with aging (r = 0.7) whereas no relationship to body surface was seen (r = 0.3); the elasticity-stiffness parameters (aortic wall distensibility, aortic wall stress, wall stiffness index, wall elasticity index and modulus) of major vessels in senior athletes (Group B), were not different (p > 0.05) from military young men (Group A), although they were significantly lower (p < 0.001) in Group C patients; wall elasticity was lower in Group C patients (versus both Group A and B). Altered compliance might be the consequence of vessel structural changes and may contribute to reduce blood flow to the coronary arteries. Our data suggest that sports activity has beneficial effects; physical characteristics of great vessels do not show age-related changes.

[Comparative echocardiographic and vectorcardiographic study of 17 patients with Duchenne muscular dystrophy (author's transl)].

Cardiac impairment in Duchenne muscular dystrophy (DMD) is well known since many years. Degeneration of myocardial fibers and progressive scarring of the left ventricle, especially in the postero-basal and lateral portions, represent the habitual cardiac pathologic features of post-mortem investigations. Nevertheless many questions about etiopathogenesis and pathophysiology of "DMD cardiomyopathy" are still debated. Clinical, vectorcardiographic (VCG) and echocardiographic (ECO) data of 17 patients suffering from DMD are here reported. Patients were subdivided in two groups according to age: A) subjects from 4 to 10 yrs. (mean 0.22 +/- 1.82 yrs.), 10 cases; B) subjects from 11 to 20 yrs. (mean 15.2 +/- 2.8 yrs.), 7 cases. Both patients groups were compared with age-matched normal controls (group A1 and B1). Our results show: 1) cardiac clinical symptoms and signs, even if is present in infancy, become more evident in adult age; 2) echocardiogram allows an early diagnosis and accurate follow-up of such cardiac pathology. Group A patients, in comparison with his own control group, exhibited a significant impairment of the left ventricular function indexes (PWE, IVSE, SV, Vcf, EF%, delta S%). Moreover the older group of patients (group B), besides the alteration of the above mentioned indexes, exhibited a significant decrease of the PWT and an impairment of DEVM. This, in agreement with other Authors, gives evidence to the progressive deteriorating of cardiac function in DMD. 3) A significant correlation between ECO and VCG data is lacking. Nevertheless VCG also displays a clear tendency to get worse with age. Vectorcardiographic features well agree with the post-mortem findings of a progressive but scattered myocardial fibrosis with elective localization in postero-basal and lateral (free wall) portions of left ventricle. 4) For the most part, in our patients, cardiological instrumental findings (ECO and VCG) are well in agreement with clinical data and natural history of "DMD cardiomyopathy". The afore said methods of investigation appear very useful in the diagnostic and therapeutic management of such patients.

Suture in oral surgery. A comparative study.

AIM: The aim of the present paper is to continue the previous study, with 52 new additional cases, confronting in vivo the behavior of 4 different suture materials (Ethibond Excel, Monocryl, silk and Vicryl) in oral surgery. METHODS: The clinical aspects have been particularly underlined: the intraoperative easy handling, the estate of the nodes and the resistance of the thread, the plaque accumulation, the tissue response in the short term (within 3 weeks) as well as in the long term (90 days), all estimated with objective parameters. RESULTS: Fifty-two out of a total of 55 new subjects included in the program have been followed throughout all the experimentation. Of the remaining 3, 1 didn't come for the suture removal, the second had a bleeding phenomenon 2 days after surgery and he went to the emergency department where sutures were replaced. The last one refused to come back for the 90 days control. These patients have been excluded from the experimentation. Data regarding the 52 patients are: plaque index recorded on the suture (Visible Plaque Index), number and percentage of sutures lost before 7/10 days, adverse reactions observed on the surgical site (14/20 days), total plaque index, and healing level and dental-periodontal status at 90 days. CONCLUSIONS: The clinical healing at 90 days was the same for all the different threads, differently from what happened in the critical postoperative period (within the 3 weeks).
