There was a significantly greater reduction in horizontal furcation depth and a comparatively lower incidence of postoperative pain/swelling following enamel matrix derivative compared to membrane therapy.

Systemic diseases affecting the host response as primary immunodeficiencies or secondary defects caused by lack of nutrients or changes in the local tissues are very often accompanied by early-onset prepubertal periodontitis. Local treatment in combination with systemic antibiotics may in milder forms improve the situation, but in many cases the success is questionable and premature loss of teeth occurs. Since the genetic basis of many of the diseases has been identified, future developments permit the correction of at least some of these defects by gene therapy.

The aim of this prospective controlled randomized clinical trial was to evaluate the additional effect of platelet-rich plasma (PRP) in attachment gain. Twenty-two patients showing contralateral intrabony defects were included. Defects were randomized to beta-TCP (Cerasorb) in combination with PRP (test) or alone (control). Probing pocket depth (PPD), clinical attachment level (CAL), and relative AL (RAL) were assessed at the first, initial, re-evaluation (or basis examinations) and 6 months after surgery. Defect dimensions were recorded at baseline surgery (day 0) and during re-entry surgery (after 6 months), with vertical depth of the defect as primary outcome variable. An early healing index (EHI) was assessed 3 days, 1, 2 and 4 weeks after surgery. Both treatments led to clinical improvements. The median reduction of open vertical depth was 1.9 mm (interquartile intervals, 0.75 and 2.5 mm) at test sites, compared with 2.6 mm (1.8 and 3.5 mm) at control sites (p = 0.19, Wilcoxon). The median reductions of PPD and CAL at the four sites in close proximity to the defect in the interproximal area at test sites were 0.8 and 0.28 mm, and at control sites 0.4 and 0.13 mm, respectively. The EHI showed a reduction from grade 3 after 3 days to grade 1 after 4 weeks. PRP did not improve the results achieved with beta-TCP in the treatment of intrabony defects.
