Association between defect morphology and healing of intrabony defects treated with minimally invasive non-surgical therapy: A pilot exploratory analysis of two cohorts.

Objective: The aim of this study was to explore the associations between defect morphology (defined by clinical and radiographic parameters) and the healing of periodontal intrabony defects treated with minimally invasive non-surgical therapy (MINST).

Background Data: MINST has shown to result in favorable clinical and radiographic improvements in intrabony defects. However, it is not clear which types of intrabony defects are most suitable for this treatment.

Minimally Invasive Non-Surgical Technique in the Treatment of Intrabony Defects-A Narrative Review.

Intrabony defects occur frequently in periodontitis and represent sites that, if left untreated, are at increased risk for disease progression. Although resective or repair procedures have been used to treat intrabony defects, aiming at their elimination, the treatment of choice is surgical periodontal regeneration. The development of periodontal regeneration in the last 30 years has followed two distinctive, though totally different, paths.

Enamel matrix derivative as an adjunct to minimally invasive non-surgical treatment of intrabony defects: A randomized clinical trial.

Aim: To compare the efficacy of minimally invasive non-surgical technique (MINST) with or without enamel matrix derivative (EMD) in the treatment of intrabony defects ≤7 mm.

Materials And Methods: Thirty-six patients were randomly assigned to the two groups. The control group received MINST, while the experimental MINST+EMD.

Soft-Tissue Changes After Using Collagen Matrix Seal or Collagen Sponge With Allograft in Ridge Preservation: A Randomized Controlled Volumetric Study.

The objective of this study is to assess alterations in buccal soft-tissue contour after alveolar ridge preservation (ARP) using either a collagen matrix seal (CMS) or a collagen sponge (CS) as barriers with freeze-dried bone allograft (FDBA). Participants (28 total) were randomly assigned to the CMS group or CS group (14 participants each). The same clinical steps were used in both barriers.

Guided implant surgery risks and their prevention.

Ideal implant placement may reduce surgical complications, such as nerve injury and lingual cortical plate perforation, and minimize the likelihood of functional and prosthetic compromises. Guided implant surgery (GIS) has been used as the means to achieve ideal implant placement. GIS refers to the process of digital planning, custom-guide fabrication, and implant placement using the custom guide and an implant system-specific guided surgery kit.

Comprehensive Treatment of Severe Periodontal and Periimplant Bone Destruction Caused by Iatrogenic Factors.

Dental implant success requires placement after periodontal therapy, with adequate bone volume, plaque control, primary stability, control of risk factors, and use of well-designed prostheses. This report describes the surgical and prosthetic management of a patient with severe iatrogenic periodontal/periimplant bone destruction. A 55-year-old female smoker with fixed partial dentures (FPDs) supported on teeth and implants presented with oral pain, swelling, bleeding, and a 10-year history of multiple implant placements and implants/prosthesis failures/replacements.

Extraoral Uses of Autologous Oral Soft Tissue Grafts: A Different Bridge Between Mouth and Body Health.

Focused Clinical Question: Are there any extraoral uses for intraoral soft tissue grafts? Summary: Despite extensive literature on the intraoral uses of soft tissue autografts harvested from oral sites, the periodontal literature is lacking information on the extraoral uses of such grafts. The purpose of this article is to review the autologous use of certain oral soft tissue grafts for extraoral indications. A literature search revealed that several medical specialties, including otolaryngology, ophthalmology, dermatology, plastic surgery, and urology, have a track record of positive outcomes with the use of free gingival, buccal fat pad, and buccal mucosa grafts for a wide variety of reconstructive procedures at diverse body sites.

Efficacy of collagen matrix seal and collagen sponge on ridge preservation in combination with bone allograft: A randomized controlled clinical trial.

Aim: To test whether the use of collagen matrix seal (CMS) results in similar hard and soft tissue remodelling to that with collagen sponge (CS) used as barriers 4 months following alveolar ridge preservation (ARP), in combination with freeze-dried bone allograft (FDBA).

Materials And Methods: Twenty-eight patients were randomly assigned to the two groups. Clinical and radiographic measurements were recorded with the same stent at baseline and 4 months for standardization.

Prevalence, Etiology and Treatment of Peri-Implant Mucositis and Peri-Implantitis: A Survey of Periodontists in the United States.

Background: Currently, information available on the exact prevalence and standard therapeutic protocol of peri-implant diseases is insufficient. The aim of this survey was to investigate the perceived prevalence, etiology, and management of peri-implant mucositis and peri-implantitis by periodontists in the United States.

Methods: A twenty-question survey was developed.

Generalized Aggressive Periodontitis Associated With a Plasma Cell Gingivitis Lesion: A Case Report and Non-Surgical Treatment.

Introduction: Plasma cell gingivitis (PCG) is an unusual inflammatory condition characterized by dense, band-like polyclonal plasmacytic infiltration of the lamina propria. Clinically, it appears as gingival enlargement with erythema and swelling of the attached and free gingiva and is not associated with any loss of attachment. The aim of this report is to present a rare case of severe generalized aggressive periodontitis (GAgP) associated with a PCG lesion that was successfully treated and maintained non-surgically.

Alveolar ridge preservation using xenogeneic collagen matrix and bone allograft.

Alveolar ridge preservation (ARP) has been shown to prevent postextraction bone loss. The aim of this report is to highlight the clinical, radiographic, and histological outcomes following use of a bilayer xenogeneic collagen matrix (XCM) in combination with freeze-dried bone allograft (FDBA) for ARP. Nine patients were treated after extraction of 18 teeth.

Severe Localized Gingival Recession Developing During Pregnancy.

Introduction: Gingival recession typically develops over a long period of time. Development or progression of gingival recession in a short time and in the absence of acute trauma is exceedingly rare. The aim of this case report is to present a case of severe gingival recession developing in a systemically healthy patient during the last trimester of a routine pregnancy.

Enamel matrix derivative in intrabony defects: prognostic parameters of clinical and radiographic treatment outcomes.

Background: The purpose of this retrospective case series study is to identify possible preoperative parameters that could predict postoperative probing depth (PD), clinical attachment level (CAL) gain, or radiographic defect resolution in intrabony defects treated with enamel matrix derivative (EMD).

Methods: Sixty-one chronic periodontitis patients, each contributing a 2- or 3-wall intrabony defect treated with EMD, were included. Clinical parameters recorded included the following: PD; CAL; gingival margin position; supracrestal soft tissue (SST); surgical distances of cemento-enamel junction (CEJ) to bone crest (CEJ-BC), CEJ to base of the defect (CEJ-BD), and BC to BD (BC-BD); and depth of 2- and 3-wall components.

Subepithelial connective tissue graft for root coverage: a case report of an unusual late complication of epithelial origin.

Background: The subepithelial connective tissue graft (SCTG) is one of the most used and predictable periodontal plastic surgery procedures; reports of late complications are very rare. This article presents an SCTG case with a previously unreported late complication of epithelial origin, and we suggest a potential link between the patient's dermatologic condition and this complication. Late SCTG complications also are reviewed.

EDTA gel root conditioning: lack of effect on clinical and radiographic outcomes of intrabony defect treatment with enamel matrix derivative.

Background: The adjunctive use of enamel matrix derivative (EMD) in the surgical therapy of intrabony defects results in improved outcomes compared to surgical debridement alone. However, the role of EDTA root conditioning in EMD therapy has not been investigated. The purpose of this study was to compare the 12-month outcomes of EMD application with and without EDTA root conditioning in intrabony defect surgical therapy.

Clinical and radiographic comparison of three regenerative procedures in the treatment of intrabony defects.

The purpose of this study was to compare clinically and radiographically the results obtained following application of (1) commercially available demineralized freeze-dried bone allograft (DFDBA), (2) guided tissue regeneration (GTR) using a bioabsorbable polylactic acid softened with citric acid ester barrier, and (3) enamel matrix derivative gel (EMD), in the treatment of two- and three-walled intrabony defects. The study included 39 patients--12 in the DFDBA group, 12 in the GTR group, and 15 in the EMD group--each with one treated defect. Clinical measurements, Plaque Index, Gingival Index, probing depths, clinical attachment levels, and recession were comparable in the three groups at baseline.
