Lasers in minimally invasive periodontal and peri-implant therapy.

Laser therapy has the potential to be an effective, minimally invasive procedure in periodontal therapy. The aim of the present review was to survey the relevant literature on the clinical application of lasers as a minimally invasive treatment for periodontitis and peri-implant disease. Currently, there are a large number of published clinical studies and case reports that evaluate the adjunctive use of diode, carbon dioxide, neodymium-doped yttrium aluminium garnet (Nd:YAG), erbium-doped yttrium aluminium garnet (Er:YAG) and erbium, chromium-doped: yttrium, scandium, gallium, garnet (Er,Cr:YSGG) lasers or antimicrobial photodynamic therapy for nonsurgical and minimally invasive surgical treatment of periodontal pockets.

Periodontal and peri-implant wound healing following laser therapy.

Laser irradiation has numerous favorable characteristics, such as ablation or vaporization, hemostasis, biostimulation (photobiomodulation) and microbial inhibition and destruction, which induce various beneficial therapeutic effects and biological responses. Therefore, the use of lasers is considered effective and suitable for treating a variety of inflammatory and infectious oral conditions. The CO2 , neodymium-doped yttrium-aluminium-garnet (Nd:YAG) and diode lasers have mainly been used for periodontal soft-tissue management.

Background: Efficient calculus removal is a primary goal in periodontal therapy. Diamond-coated ultrasonic inserts (DIs) offer promise for improved scaling and were evaluated in vitro.

Methods: Extracted human teeth with moderate to severe calculus had areas of calculus ( approximately 5 x 5 mm) delineated with small burs.

Evaluation of allogeneic bone graft substitute for treatment of periodontal osseous defects: 6-month clinical results.

This article is an initial clinical evaluation of the use of Puros, a specially processed allogeneic bone graft substitute, for treatment of periodontal osseous defects. Nine patients with chronic periodontitis contributed 1 osseous defect each. Clinical and surgical measurements were taken at the time of the initial grafting and 6 months later at the time of a surgical re-entry.

Periodontal regeneration with peptide-enhanced anorganic bone matrix in particulate and putty form in dogs.

Background: Peptide-enhanced (using the peptide 15 [P-15] synthetic peptide) anorganic bone matrix (ABM) particulate (PPart) grafts have demonstrated clinical and histologic success in human periodontal defects. Dispersion of ABM/P-15 in sodium hyaluronate carrier (PPutty) improves the handling properties of the graft material. The healing of ABM/P-15 particulate and ABM/P-15 putty was compared in critical-sized fenestration defects in 16 mongrel dogs.

Effect of locally delivered doxycycline hyclate on human fibroblast attachment to subgingival calculus.

Background: Clinical studies using locally applied doxycycline hyclate (DHV) have demonstrated significant probing depth reduction and gain in clinical attachment as a monotherapy without scaling and root planing. The mechanism for this attachment level gain to the non-root planed tooth is not understood. The purpose of this study was to investigate the effect of locally applied doxycycline hyclate on human gingival fibroblast attachment to subgingival calculus on contaminated root surfaces.

Outer membrane vesicles from Porphyromonas gingivalis affect the growth and function of cultured human gingival fibroblasts and umbilical vein endothelial cells.

Background: The purpose of this study was to examine the effects of outer membrane vesicles (OMV) obtained from Porphyromonas gingivalis (Pg) on the growth and function of human gingival fibroblasts (HGF) and human umbilical vein endothelial cells (HUVEC).

Methods: OMV were obtained from a cell-free growth medium of Pg ATCC 33277 by 40% NH2SO4 precipitation and ultracentrifugation. Cell proliferation was measured by 3H-thymidine incorporation into growing HGF and HUVEC.

Root surface removal and resultant surface texture with diamond-coated ultrasonic inserts: an in vitro and SEM study.

Background: A new diamond-coated ultrasonic insert has been developed for scaling and root planing, and it was evaluated in vitro for the amount of root surface removed and the roughness of the residual root surface as a result of instrumentation.

Methods: 48 extracted single-rooted human teeth were ground flat on one root surface and mounted (flat side up) in PVC rings of standard height and diameter with improved dental stone. Each tooth surface was treated with either a plain ultrasonic insert (PI), an ultrasonic insert with a fine grit diamond coating (DI) or sharp Gracey curettes (HI).

Comparative evaluation of decalcified and non-decalcified freeze-dried bone allografts in rhesus monkeys. I. Histologic findings.

Background: Controversy exists regarding the relative merits of decalcified (DFDBA) and non-decalcified (FDBA) freeze-dried bone allografts when used in periodontal or other oral surgical procedures.

Methods: Under typical sedation, six rhesus monkeys had nylon mesh cylinders containing either DFDBA or FDBA implanted into surgically created vertical grooves on the facial aspects of all posterior quadrants. Each quadrant received three cylinders containing one type of bone, plus one empty cylinder (E) as negative control, and the full thickness flaps were closed to completely cover the cylinders.

Gingival/soft tissue abscess following subepithelial connective tissue graft for root coverage: report of three cases.

Background: The subepithelial connective tissue graft (SCTG) is a predictable technique for root coverage. The small number of potential postoperative problems make SCTG the current treatment of choice for reversing gingival recession.

Methods: The purpose of this article is to report three cases of complications after the use of an SCTG where an abscess occurred following the initial healing phase.

Use of HTR synthetic bone grafts in conjunction with immediate dental implants.

Immediate placement of dental implants in fresh extraction sockets is associated with remaining voids around the implants and often a partial dehiscence or thinning of the facial alveolar plate. Nine patients had Bioplant HTR synthetic bone used as a ridge preservation/augmentation material in conjunction with immediate placement of 10 implants. Hard tissue replacement (HTR) was used to fill the remaining socket void and enhance the facial ridge width, and the wound closed as completely as possible.

Periodontal disease in HIV-positive individuals: association of periodontal indices with stages of HIV disease.

Background: Periodontal disease has been previously associated with human immunodeficiency virus (HIV) infection, and HIV infection has been considered a modifier of periodontal disease. The aim of this study was to report the prevalence and severity of periodontal disease in a population of HIV-positive individuals and to investigate the association between clinical periodontal indices and the stage of HIV disease, as expressed by CD4 cell counts.

Methods: Thirty-nine male HIV-positive patients were recruited and a medical history was taken.

Evaluation of hard tissue replacement composite graft material as a ridge preservation/augmentation material in conjunction with immediate hydroxyapatite-coated dental implants.

Background: Immediate placement of dental implants (DI) in fresh extraction sockets is associated with remaining voids around the DI and often a partial dehiscence or thin facial alveolar plate. Bone replacement grafts are often used to correct these problems. This study evaluated the use of a layered composite of PMMA (poly-methyl-methacrylate), PHEMA (poly-hydroxyl-ethyl-methacrylate), and calcium hydroxide grafts (HTR) as a ridge preservation/ augmentation material used in conjunction with an immediate DI placement technique.
