“…Regarding the results of Matuliene et al., FI significantly impairs tooth survival most likely due to deeper residual pockets following NST, leading to persisting attachment loss 17 . These results confirm that due to well‐known difficulties in the access and cleanability of the furcation area that is frequently further complicated by anatomical variations FI represents one of the greatest challenges in periodontal therapy causing persistence and recurrence of infection 44–46 …”

“…17 These results confirm that due to well-known difficulties in the access and cleanability of the furcation area that is frequently further complicated by anatomical variations FI represents one of the greatest challenges in periodontal therapy causing persistence and recurrence of infection. [44][45][46] Increased tooth mobility has been previously shown to be associated with initially higher PPD. 19 Regarding PPD reduction, however, no significant difference was evident herein when values were adjusted for baseline depth.…”

BackgroundTo investigate tooth‐related factors that influence the reduction of probing pocket depths (PPD) after non‐surgical periodontal therapy (NST).MethodsSeven hundred forty‐six patients with a total of 16,825 teeth were included and retrospectively analyzed. PPD reduction after NST was correlated with the tooth‐related factors; tooth type, number of roots, furcation involvement, vitality, mobility, and type of restoration; using logistic multilevel regression for statistical analysis.ResultsNST was able to reduce probing depth overall stratified probing depths (1.20 ± 1.51 mm, p ≤ 0.001). The reduction was significantly higher at teeth with higher probing depths at baseline. At pockets with PPD ≥ 6 mm, PPD remains high after NST. Tooth type, number of roots, furcation involvement, vitality, mobility, and type of restoration are significantly and independently associated with the rate of pocket closure.ConclusionsThe tooth‐related factors: tooth type, number of roots, furcation involvement, vitality, mobility, and type of restoration had a significant and clinically relevant influence on phase I and II therapy. Considering these factors in advance may enhance the prediction of sites not responding adequately and the potential need for additional treatment, such as re‐instrumentation or periodontal surgery, to ultimately achieve the therapy end points.

“…In addition to intrabony defect morphology, the degree of furcation involvement is a major risk factor influencing the long-term outcomes and tooth mortality [ 39 , 40 ]. According to a meta-analysis, the relative risk of tooth loss due to the presence of furcation involvement is 2.21 (95% confidence interval = 1.79–2.74, p < 0.001) up to 15 years of follow-up [ 39 ].…”

Background The aim of this retrospective cohort study was to evaluate the long-term clinical and radiographic outcomes and survival of teeth in periodontal regenerative treatment of intrabony defects using combined enamel matrix protein derivative (EMD) and deproteinized porcine bone mineral (DPBM) compared to EMD alone. Methods A total of 333 intrabony defects in 176 patients (mean age: 54.7 ± 8.9 years) were followed-up for 58.6 ± 11.2 (range, 25–78) months after periodontal regenerative treatment. Changes in clinical (pocket probing depth and clinical attachment level) and radiographic (defect depth and defect width) parameters were analyzed using serial periapical radiographs. Kaplan–Meier and multivariate Cox proportional-hazards regression analyses for tooth loss were also performed. Results Compared to periodontal surgery with EMD alone with a mean follow-up of 5 years, combined EMD and DPBM showed significantly better gain in clinical attachment level (EMD and DPBM: 2.8 ± 2.3 mm vs. EMD alone: 2.2 ± 2.2 mm) and reduction in probing pocket depth (EMD and DPBM: 2.8 ± 1.8 mm vs. EMD alone: 2.3 ± 1.8 mm), defect depth (EMD and DPBM: 2.5 ± 2.4 mm vs. EMD alone: 2.0 ± 2.4 mm) and defect width (EMD and DPBM: 0.6 ± 1.0 mm vs. EMD alone: 0.2 ± 1.3 mm). The overall survival rates of the teeth were 91.48% and 95.20% in the patient- and tooth-based analyses, respectively, showing no statistically significant difference. Conclusions Within the limitations of the current study, combined EMD and DPBM offered additional clinical and radiographic benefits over a mean of 5 years compared to EMD alone. However, tooth loss did not differ significantly between the two groups. Clinical relevance Compared to EMD alone, combined EMD and DPBM for intrabony defects has additional clinical advantages; however, patient- and tooth-related risk factors must be considered when performing periodontal regenerative surgery.

“…The grade of the horizontal and/or vertical component of the furcation defect affects the prognosis of molars with FI and is a key parameter when evaluating the outcomes of periodontal regeneration [22,23]. Tonetti in 2017 [7] evaluated bone loss by using periapical radiographs taken with the parallel technique and conducted clinical examination of PD and CAL.…”

Background The relationship between the anatomy of the interradicular space and success in regenerative therapy of furcation defects is discussed in this paper. The goal of this retrospective, multicenter clinical study is to clinically evaluate the relationship between the interradicular conformation and regenerative therapy success with the use of a novel measurement method. Methods One hundred thirty-eight radiographs of mandibular molars with furcation defects that had been treated with regenerative therapy were collected from six clinical centers. Data on the type of therapy and clinical parameters before and after treatment (follow-up of at least 12 months) were collected. The radiographs (before surgery and at least 12 months postoperatively) were measured with a visual evaluation method by a blind operator using graphics software. Results Success, defined as a reduction in horizontal and vertical furcation involvement, decrease in probing depths, and increase in clinical attachment level, was statistically assessed on 138 regenerated molars sites and were related to clinical variables such as age, sex, center, and treatment. No correlation was found between success in regenerative therapy and the conformation of the interradicular space, measured with a visual ratio method and a standard linear measurement. At the univariate analysis, the parameters that had a correlation with success were center, extent of furcation involvement, treatment, and sex. The use of enamel matrix derivative (EMD) seemed to be the most favorable therapy, with increase in CAL gain and reduction of vertical or horizontal furcation involvement. Conclusions The regenerative outcome was not significantly influenced by the anatomy of furcation. The center, the degree of furcation involvement, sex, and treatment (EMD) were significantly associated with higher success of periodontal regeneration.
