Knochenbildung bei regenerativ behandelten Gingivarezessionen – Ein Fallbericht.
No full textDieser Fallbericht zeigt das Potenzial der Raumschaffung für die Knochenneubildung bei einem Rezessionsdefekt unter einer nicht resorbierbaren Barriere. Dabei wurde das Konzept der
Zellexklusion bewusst nicht berücksichtigt. Ein tiefer und breiter gingivaler Rezessionsdefekt, der mit einer 10 mm tiefen Knochendehiszenz vergesellschaftet war, wurde durch eine Lappenoperation mit
Koronalverschiebung im Zusammenhang mit einer titanverstärkten e-PTFE-Membran behandelt.
Beim Einsetzen wurde die Membran bewusst perforiert, um ein Einwachsen von Gewebe und eine
Kolonisierung des Zwischenraums zwischen Membran und Wurzeloberfläche durch Zellen zu ermöglichen,
die normalerweise durch GTR ausgeschlossen werden. Die klinische Untersuchung nach der
Phase der Gewebereifung zeigte eine deutliche Knochenregeneration und einen Attachmentgewinn
auf der zuvor exponierten Wurzeloberfläche, die auch langfristig erhalten blieben
Chronic Relapsing Allergic Contact Cheilitis from a Toothpaste. A Case Report.
No full textThe present case report describes the case of a 25 year-old Caucasian man whose Cheilitis was initially erratically diagnosed and treated as an Herpetic Cheilitis, and was then correctly identified as a Toothpaste Allergic Contact Cheilitis. The remission of the pathology was achieved through the elimination of the allergen, while the clinical symptoms were controlled by means of topic application of corticosteroids, with a complete and stable restitutio ad integrum of the perioral tissues
Flap design for periodontal healing.
No full textThe aim of this chapter was to describe flap designs aimed at establishing favorable circumstances which may eventually enhance the clinical outcome of reconstructive procedures in
periodontal intraosseous defects. The selection of a specific flap design and related suture technique must be based on the predictability to achieve optimal primary closure of the healing
wound, thus creating an essential biologic prerequisite for periodontal regeneration. The surgical reconstruction of the lost attachment apparatus is a highly technique-sensitive procedure,
where the choice and the technical performance of the flap design in a specific patient with a specific defect plays a key role. The clinical value to adapt the selection of the surgical approach to the anatomy of the treated area as well as the physical and biological
characteristics of the regenerative materials adopted has been emphasized (Trombelli et al.2002, 2006; Cortellini and Tonetti 2005; Trombelli 2005, 2010). Along with the use of the
appropriate regenerative technology, the surgical procedures should provide conditions for primary intention healing supporting adequate wound stability allowing uneventful tissue formation and maturation. In this respect, flap design and suture technique appear of paramount importance to maximize the reconstructive potential of membrane, graft biomaterials and biological agents

A review of factors influencing the incidence and severity of plaque-induced gingivitis
No full textAn individual variation in the gingival inflammatory response to the dental biofilm has been demonstrated. This variability can be observed between individuals with neither quantitative nor qualitative differences in plaque accumulation. The reported significant differences in gingival inflammatory response under quantitatively and/or qualitatively almost identical bacterial challenge suggest that the gingival response to plaque accumulation may be an individual trait, possibly genetic in origin. The most recent classification of periodontal diseases acknowledges that the clinical expression of plaque-induced gingival inflammation can be substantially modified by systemic factors, either inherent to the host or related to environmental influences. The aim of the present literature review is to describe (i) the factors influencing the development of plaque-induced gingivitis as well as (ii) those metabolic, environmental and systemic factors which have a direct impact on the etiopathogenetic pathway of plaque-induced gingivitis, thus altering the nature or course of the gingival inflammatory response to dental biofilm
Space provision ensures bone formation in gingival recession defects treated by GTR: a case report.
No full textThe present case report will show the potential of space-provision for bone regrowth underneath a non-resorbable barrier device in a recession defect where the concept of cell exclusion was intentionally neglected. A deep and wide gingival recession defect associated with a 10-mm deep bone dehiscence was treated by a coronally advanced flap in conjunction with a titanium-reinforced ePTFE membrane. At the time of membrane positioning, the device was intentionally perforated to allow for tissue ingrowth and colonization of the space between the membrane and the root surface by means of cell lines which are usually excluded under GTR provision. Clinical evaluation after tissue maturation phase revealed a substantial bone regeneration and attachment gain onto the previously exposed root surface which were maintained long-term
Prognosi parodontale: metodo di valutazione obiettiva e implicazioni clinico-pratiche.
No full textLa valutazione del rischio è il processo nel quale vengono effettuate stime qualitative o quantitative sulla probabilità che un evento avverso ha di verificarsi come risultato dell’ esposizione a specifici fattori di rischio. La valutazione dei determinanti del rischio in Parodontologia è fondamentale per l’ identificazione precoce dei soggetti ad alto rischio di perdere denti a causa della parodontite e per la formulazione di strategie preventive e terapeutiche personalizzate che consentano il controllo mirato dei fattori di rischio. Scopo del presente lavoro è illustrare il metodo di valutazione del rischio parodontale elaborato e adottato dall’ Università di Ferrara. Tale metodo è di facile e rapido utilizzo e clinicamente applicabile a qualsiasi tipologia di paziente. Il metodo è basato sulla valutazione e sulla elaborazione dei rischi associati a 5 fattori/indicatori di rischio, ricavati da dati anamnestici (fumo, Diabete Mellito), da parametri parodontali clinici (numero di tasche parodontali con profondità di sondaggio uguale o superiore a 5 mm, Indice di Sanguinamento al sondaggio) e parametri derivati (rapporto perdita ossea/età). I fattori/indicatori di rischio considerati nel metodo sono quelli maggiormente validati dalle prove scientifiche disponibili. La applicazione clinica del metodo viene illustrata mediante un caso clinico paradigmatico
Efficacy of triclosan-based toothpastes in the prevention and treatment of plaque-induced periodontal and peri-implant diseases
No full textAim: To evaluate the efficacy of triclosan (T)-based toothpaste formulations in the prevention and treatment of plaque-induced periodontal and peri-implant diseases. Methods: A review of the existing literature was conducted with a systematic approach in order to retrieve pertinent articles. Results and conclusions: i) Compared with a control fluoride dentifrice, a fluoride dentifrice containing T formulations provides a more effective level of plaque control and gingival health in patients affected by gingivitis; ii) 0.3% T/2% copolymer/0.243% NaF formulation and 0.3% T/0.13% Ca glicerophosphate/1000 ppm F toothpaste in a natural Ca carbonate base seem the most effective T-based toothpaste formulations in controlling plaque and gingival inflammation in patients with gingivitis or mild/moderate periodontitis over a 6-month period; iii) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation can reduce clinical attachment loss in young adolescents when compared with a 0.243% NaF toothpaste formulation, the magnitude of the difference being greater for patients with deep periodontal pockets at baseline; iv) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation is either similarly or more efficacious in preventing the progression/recurrence of periodontal destruction when compared to a conventional fluoride toothpaste; v) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation seems to be more effective than a fluoride toothpaste formulation in controlling the severity of mucosal inflammation, the incidence of mucosal bleeding as well as reducing probing pocket depth around dental implants
Implementation of Patient-Based Risk Assessment in Practice
No full textThe wide heterogeneity in judgments generated by subjective risk assessment as observed among operators (even specialists in the periodontal field) and its negative impact on estimated treatment call for the use of standardized, objective tools for periodontal risk assessment. The use of such tools is currently recognized as a standard of care in dental practice and is encouraged by the influential institutions in the oral and dental field. Benefits related to their application are perceived by both practitioners (as improvements in the identification of the most relevant risk factors, effectiveness of communication, as well as patients’ education, satisfaction, and acceptance of treatment) and patients (as improved awareness of the nature and severity of their disease and higher intentions to adhere to instructions). To date, the use of four risk assessment tools (PRC, PRA, UniFe/PerioRisk, and DRS) in the periodontal field is supported by the results of longitudinal studies demonstrating the existence of a positive association between risk scores and the extent of disease progression. Although the amount and strength of evidence differ substantially between tools, they are designed for clinicians as validated instruments to apply either at first visit (based on the assumption that no periodontal treatment will be administrated) or during supportive periodontal therapy (assuming that conditions will be supervised through a personalized maintenance program). The extra time required for assessment and lack of sufficient validation to tailor preventive/therapeutic interventions on risk levels still represent major limitations for the application of risk assessment tools in daily practice. However, the use of novel, simplified tools is expected to overcome these barriers in the near future, making risk assessment standard and universally acceptable
