“…1 According to the glossary of terms published by the American Academy of Periodontology, a furcation involvement exists whenever periodontal disease has caused resorption of bone into the bifurcation or trifurcation of a multirooted tooth. 2 Several classifications of furcation involvement based on the degree of horizontal and/or vertical probe penetration have been developed.…”

“…8 Nonetheless, little is known about the practical extraction methods for IR, except that an elevator should not be used and the beak of the conventional extraction forceps should be placed on the crown above the cementoenamel junction. 5 Many clinicians regard IR difficult because of the scant information on specific extraction methods.…”

Purpose: Intentional replantation (IR) is a suitable treatment option when nonsurgical retreatment and periradicular surgery are unfeasible. For successful IR, fracture-free safe extraction is crucial step. Recently, a new extraction method of atraumatic safe extraction (ASE) for IR has been introduced. Patients and Methods: Ninety-six patients with the following conditions who underwent IR at the Department of Conservative Dentistry, Seoul National University Bundang Hospital, in 2010 were enrolled in this study: failed nonsurgical retreatment and periradicular surgery not recommended because of anatomical limitations or when rejected by the patient. Preoperative orthodontic extrusive force was applied for 2-3 weeks to increase mobility and periodontal ligament volume. A Physics Forceps was used for extraction and the success rate of ASE was assessed. Results: Ninety-six premolars and molars were treated by IR. The complete success rate (no crown and root fracture) was 93% (n = 89); the limited success rates because of partial root tip fracture and partial osteotomy were 2% (n = 2) and 5% (n = 5), respectively. The clinical and overall success rates of ASE were 95% and 100%, respectively; no failure was observed. Conclusions: ASE can be regarded as a reproducible, predictable method of extraction for IR.

“…However, in spite of compliance with SPT regimes, residual and relapsed pocketing after ICRT has been shown in a number of long-term studies (> 10 years) to develop in risk patients and at certain sites even when compliance with SPT is given (20). The at-risk sites are especially those that are ≥ 6 mm in dept (21,22), molars and premolars (21), furcations and root concavities (23); all parameters that hinder adequate plaque removal. According to the 5th European Workshop on Periodontology (22), this constitutes periodontal disease progression (also as a factor of a suboptimal ICRT outcome), whose treatment has yet to be satisfactorily resolved.…”

OBJECTIVE: To evaluate a novel device for its efficacy in removing experimental biofilm from root surfaces and its potential for concomitantly removing/roughening the surface substance. METHODS AND MATERIALS: A novel acrylic rotary device (biofilm remover, BR) was tested in vitro in three experiments: surface loss, surface roughness [positive controls: Perioset (PS) and Proxoshape (PR)] and biofilm removal [positive controls: ultrasonic (US) and PS]. Surface loss/surface roughness was evaluated for dentin samples instrumented for three 20 s periods. The calcium removed during instrumentation was analysed after each interval and cumulatively, using atomic absorption spectrophotometry (AAS). Surface roughness was measured using profilometric analysis. Biofilm removal was evaluated on dentin specimens coated with a 64.5 h 6-species in vitro formed biofilm, after one 20 s treatment. Surface loss was analysed using anova with Scheffé post hoc test, and surface roughness/biofilm removal was analysed using Mann-Whitney test (all P 0.05). RESULTS: Significantly less substance loss [g (±1 SD)] was observed with the novel device at all time points, both interval and cumulative (1.0 (±0.5) versus 9.3 (±3.2) PS and 9.9 (±1.9) PR at 60 s). Surface roughness [m (95% CI)] was significantly lower for BR than for PS and PR [0.00 (-0.01, 0.08) 0.20 (0.16, 0.27) and 0.21 (0.19, 0.24) at 60 s]. Significantly less biofilm bacteria remained after treatment with both BR 4.5 (-0.1, 16.2) and US 1.9 (-0.2, 14.3), compared to PS 52 (27.9, 82.1). CONCLUSIONS: The novel biofilm remover was less damaging to dentin surfaces, while removing biofilm at least as effectively as devices used in this study.
