Postoperative pain and discomfort with and without periodontal dressing in conjunction with 0.2% chlorhexidine mouthwash after apically positioned flap procedure
No full textThe purpose of this study was to evaluate patient postoperative pain experience and discomfort with and without the use of a periodontal dressing in combination with a 0.2% chlorhexidine mouthwash after internal bevelled, full thickness, apically positioned flap procedure. Twenty-four patients requiring comparable bilateral flap procedures were selected. Using a split-mouth design, one site received a periodontal dressing while the other site did not. A 0.2% chlorhexidine mouthwash (10 ml for 1 minute twice daily) was prescribed postoperatively for all patients. Pain assessment was made according to a structured, categorized scale (0 = no pain; 1 = mild pain; 2 = moderate pain; and 3 = severe pain). Analgesic drug consumption was recorded during the first postoperative week. After at least a one-month period, the second flap procedure was performed using the alternate postoperative treatment. At the conclusion of the trial, a self-administered questionnaire on postoperative experience was administered. Results indicated a similar trend for mean pain scores as assessed by patients for both dressed and undressed sides during the 7-day postoperative period. Statistical analysis revealed no significant differences between treatment groups with respect to frequency distribution of patients who did or did not take analgesics or the daily and total consumption of analgesic drops. Although patients with dressing frequently experienced eating difficulty, most stated a psychological feeling of protection and well-being with its use

Postoperative infections and tetracycline prophylaxis in periodontal surgery: A retrospective study
No full textThe aims of this retrospective study were to assess the incidence of infection after periodontal surgery, in relation to the type of surgical procedure, and the effectiveness of prophylactic tetracycline administration. Nineteen (4.4%) of 445 surgical procedures in patients who were given no tetracycline resulted in signs of infection, while two (3.8%) in patients who were treated with tetracycline resulted in signs of infection. There was no statistically significant difference between these incidences, suggesting that there is no reason for routine tetracycline prophylaxis in periodontal surgery. There was no statistically significant difference in the incidence of infection whether or not bone (ostectomy or osteoplasty) or tooth extraction was involved in the surgical procedure

Combined guided tissue regeneration, root conditioning, and fibrin-fibronectin system application in the treatment of gingival recessions. A 15-case report.
No full textThis paper describes a surgical technique to achieve root coverage in deep, wide gingival recessions using a root isolation procedure with ePTFE membrane, combined with tetracycline conditioning of the root surface and fibrin-fibronectin sealing system application. The technique was used on 15 patients with isolated mucogingival defects 4 to 6 mm deep. A large trapezium-shaped flap was raised 3 to 4 mm apical to the margin of the bone dehiscence. The root surface was thoroughly scaled by hand and rotating instruments. Tetracycline HCl solution (100 mg/ml) was topically applied for 4 minutes. Expanded polytetrafluoroethylene (ePTFE) membrane was adapted at least 1 mm coronal to the CEJ and retained in position by sling sutures. A film of fibrin-fibronectin sealing system was injected between the membrane and the root surface. The flap was sutured coronally and the membrane removed 6 weeks later. The patients were reevaluated 6 months after the reentry procedure. The mean recession depth decreased from 4.7 mm initially to 1.1 mm at the final postoperative appointment. This represents a mean root coverage of 77.4%. Mean probing depth reduction was 0.9 mm and the mean width of keratinized tissue increased from 1.8 mm preoperatively to 2.9 mm 6 months after surgery. These findings show that the treatment of buccal gingival recession using guided tissue regeneration procedure plus tetracycline root demineralization and fibrin-fibronectin glue application results in a consistent and predictable improvement of mucogingival defects
A Trabecular Metal Implant 4 Months After Placement: Clinical-Histologic Case Report
No full textINTRODUCTION: The aim of this case report was to histologically evaluate the behavior of a trabecular metal (TM) implant composed of titanium and spatial 3-dimensional tantalum (Ta) trabeculae. This study is the first human histologic case report of this implant.; CASE PRESENTATION: A TM implant was placed in a 54-year-old woman exhibiting moderate chronic periodontitis. After periodontal treatment, the implant was inserted under favorable clinical conditions. Patient was not seen for 4 months because of unrelated breast reduction surgery. At the surgical reopening, periimplant inflammation affecting the coronal third of the implant was observed 4 months after implant placement. With patient's consent, the implant was removed for histologic analysis. Histology highlighted a greater amount of bone in close contact with Ta trabeculae than titanium surfaces.; CONCLUSION: The finding of bone formation around the Ta trabeculae suggests that trabecular metal material promotes bone ingrowth for secondary implant stability. Additional evidence is needed to confirm this observation
Il grande rialzo del seno mascellare: ricerca clinica e buon senso
No full textIl posizionamento di impianti corti contestualmente alla procedura di rialzo del seno mascellare appare come una procedura sicura e predicibile, associata ad una netta riduzione dei tempi riabilitativi. Dal confronto, in termini di sopravvivenza implantare e di complicanze, tra impianti lunghi posizionati nel contesto di un grande rialzo del seno mascellare e posizionamento di impianti corti (senza alcun rialzo di seno), qesti ultimi sembrano rappresentare una valida alternativa, in quanto abbreviano in modo considerevole i tempi di trattamento e riducono i costi. Tuttavia rimangono molteplici aspetti relativi al grande rialzo del seno mascellare che devono essere ulteriormente investigati. Risulta, a distanza di 30 anni, ancora di estrema attualità l'appello della "Consensus Conference" del 1996 a realizzare studi clinici controllati randomizzati di tipo prospettico che forniscano risposte conclusive
