Diamond-coated sonic tips are more efficient for open debridement of molar furcations

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 5 2000
A comparative manikin study
Abstract Background/aims: The aim of this study was to compare the efficacy of open debridement of class II and III furcations by a new diamond-coated sonic instrument tip (Sonicparo) with a conventional sonic insert (Sonicrecall) and hand instruments (Gracey curettes). Method: Open debridement was simulated using a manikin head and standardised plastic teeth. The efficacy of debridement was examined by 3 parameters: residual root surface marker, ,tooth' weight loss and time taken for debridement. The teeth used were 1st and 2nd upper and lower molars. Upper left and lower right molars were chosen to represent class II furcation involvements and upper right and lower left molars class III furcation involvements. Each tooth was debrided 4 times with each instrument for both class of furcations. Results: The results of this study showed significantly less residual marker area comparing Sonicparo with Gracey curettes (mean difference 2.52 mm2, p<0.001). However, no significant differences in marker removal were observed between Sonicrecall inserts and the other instruments. Sonicparo inserts also took significantly less time to debride the furcation than Gracey curettes (mean difference 98.3 s, p<0.001) or Sonicrecall instruments (mean difference 74.3 s, p<0.001). However no significant differences were found between instruments concerning weight loss of the plastic teeth. Conclusions: It was concluded from this in-vitro study that the Sonicparo insert was a more efficient instrument for open molar furcation debridement than Sonicrecall and hand instruments (Gracey curettes) when considering both marker removal and debridement time.

Re-osseointegration on previously contaminated surfaces: a systematic review

CLINICAL ORAL IMPLANTS RESEARCH, Issue 2009
Stefan Renvert
Abstract Objectives: The aim of this review was to search the literature for the existing evidence of re-osseointegration after treatment of peri-implantitis at contaminated implant surfaces. Material and Methods: A search of PubMed as well as additional hand search of articles were conducted. Publications and articles accepted for publication up to November 2008 were included. Results: A total of 25 animal studies fulfilled the inclusion criteria for this review. Access surgery with closed healing has been observed to positively influence the rate of re-osseointegration when compared with non-surgical decontamination of the implant surface with open healing. Open debridement including surface decontamination may result in re-osseointegration and this integration was more pronounced on rougher than on smooth implant surfaces. The adjunctive use of regenerative procedures resulted in varying amounts of re-osseointegration. Conclusions: Re-osseointegration is possible to obtain on a previously contaminated implant surface and can occur in experimentally induced peri-implantitis defects following therapy. The amount of re-osseointegration, varied considerably within and between studies. Implant surface characteristics may influence the degree of re-osseointegration. Surface decontamination alone can not achieve substantial re-osseointegration on a previously contaminated implant surface. No method predictably accomplished complete resolution of the peri-implant defect. [source]

A retrospective analysis of two independent prospective cartilage repair studies: autogenous perichondrial grafting versus subchondral drilling 10 years post-surgery

JOURNAL OF ORTHOPAEDIC RESEARCH, Issue 2 2002
Phianne S. J. M. Bouwmeester
Background: Experimental data indicate that perichondrial grafting to restore articular cartilage defects will result in repair with hyaline-like cartilage. In contrast, debridement and drilling results in repair with fibro-cartilage. In this retrospective study the longterm clinical results of both procedures were compared to evaluate the theoretical benefit of repair with hyaline-like tissue. Methods: From two independent studies patients were selected with a cartilage defect in their knee. The selection was performed using strict inclusion criteria published elsewhere [Bouwmeester et al. Int. Orthop. 21 (1997) 313]. The patients were treated with either a perichondrium transplantation (PT group, n = 14) or with an ,open' debridement and drilling procedure (DD group, n = 11). The results of both procedures after 10,11 years were evaluated using the Hospital for Special Surgery Knee Score (HSSS), X-ray examination, clinical examination and visual analogue scales (VAS) for pain during walking and at rest. Results: Both procedures resulted in a general improvement compared to the situation before the operation. After an average of 10 years in the PT group there were three failures, in the DD group none, success rates were 78% and 100%, respectively. When comparing the successful PT patients with the DD patients, there were no differences in HSSS and VAS data. Both groups showed an equal number of irregular operation surface sites on X-ray (PT 9/11 versus DD 8/10). Conclusions: This study shows that clinically at 10 years follow-up no difference was observed between debridement and drilling and perichondrium transplantation for treatment of an isolated cartilage defect. This raises questions about ongoing research to develop methods in order to improve the results of debridement and drilling as therapy for an isolated cartilage defect in a young patient (, 40 years). © 2002 Orthopaedic Research Society.
