Aarskog-scott syndrome (AAS): a case report
No full textBackground Aarskog-Scott syndrome (AAS) is a rare developmental disorder characterised by facial dysmorphism, genital and limb anomalies as well as disproportionate acromelic short stature. Clinical diagnosis is based on physical examination and the presence of the most characteristic clinical signs. The diagnosis can be finally confirmed by molecular tests, which identify mutations in the FGD1 gene.Case Report The report outlines the orthodontic treatment of a 6-year-old male patient, who was diagnosed with AAS syndrome. He presents all facial and oral clinical signs of this syndrome. The extent of maxillary hypoplasia and early dental crowding are so significant that immediate expansion therapy is required.Conclusions Dental management of patients with AAS syndrome represents a challenge for paediatric dentists. The key to improving a patient's aesthetic, functional and psychological condition is making the correct orthodontic decision
Histological characterization of Sacco’s concentrated growth factors membrane [Caracterización Histológica de la Membrana de los Factores de Crecimiento Concentrados Sacco]
Full text linkAlong with the emerging needs of the dental patients, numerous techniques for oral tissue stimulation and regeneration were developed to be employed in the modern implant rehabilitation therapies. The Concentrated Growth Factors (CGF) are a relatively new therapeutic presidium that can be used for this purpose, enhancing the regenerative potential property of blood cells. Although literature presents numerous studies evaluating the CGF for their clinical uses and efficacy, data regarding their biological characteristics are very few. The present study evaluates and describes the CGF structural morphology by means of classical histological methods, using haematoxilin-eosin and azan mallory stains. A three layers organization with a fibrin complex network was noted, with blood corpuscular elements entrapped, especially in the most external layer. These descriptions enrich the knowledge about this new type of membrane, showing the bio-morphological side of the regenerative techniques. These findings will be useful in clinical practice for the choice of the most suitable technique in each implant rehabilitationAlong with the emerging needs of the dental patients, numerous techniques for oral tissue stimulation and regeneration were developed to be employed in the modern implant rehabilitation therapies.

Association between periodontal disease and adverse outcomes in pregnancy
No full textObjectives. Aim of this paper is to evaluate the possible effects of periodontal status on the pathogenesis of preterm low birth weight (PLBW), given the suspected correlation between periodontal diseases and PLBW. Acting as a source of bacteria, endotoxins and inflammatory mediators, periodontal diseases might cause effects both on the foetus and on his physiological environment. Materials and methods. This study enrolled a sample of 50 pregnant women who filled out an anamnestic questionnaire and went through a periodontal examination. Results. The results obtained demonstrate that periodontal conditions of pregnant women have improved in the last years and that the risk of PLBW increases in primiparous and multipa- rous women with previous spontaneous abortions. Conclusions. Periodontal condition seems to influence neither pregnancy duration nor baby weight at birth
Oral rehabilitation of maxilla: Technical consideration
No full textOral rehabilitation of edentulous maxilla is particularly difficult because of the lack of bone in correspondence of maxillary sinuses, therefore, the surgeon is forced to place implants in sites where bone is more prevalent. In addition, patients require more frequent oral immediate rehabilitation in order to reduce the discomfort related to wearing a total denture. A viable solution to provide stability and retention of the prosthesis in a short time is represented by the technique of intraoral welding supporting total denture or fixed prosthesis. This goal may be achieved thanks to the technique of welding titanium bars onto implant abutments. In fact, the procedure can be performed directly in the mouth, eliminating the possibility of errors or distortions due to prosthetic procedures. This paper describes a case report and the most recent data regarding long-term success and high predictability of intraorally-welded titanium bar in immediate loading implants
