Background and Objective: Photodynamic therapy has been advocated as an alternative to antimicrobial agents suppress subgingival species treat periodontitis. Bacteria located within dense biofilms, such those encountered in dental plaque, have found be relatively resistant therapy. In the present study, we investigated ability of photodynamic reduce number bacteria biofilms by comparing effects methylene blue on human plaque microorganisms planktonic phase biofilms. Material Methods: Dental...

Background: This study compared erbium‐doped: yttrium, aluminum, and garnet (Er:YAG) laser irradiation (100 mJ/pulse; 10 Hz; 12.9 J/cm 2 ) with or without conventional scaling root planing (SRP) to SRP only for treatment of periodontal pockets. Methods: Nineteen patients pockets from 5 9 mm were included. In a split‐mouth design, each site was allocated group: 1) SRPL, laser; 2) L, 3) SRP, only; 4) C, no treatment. Clinical parameters probing depth (PD), gingival recession, clinical...

Abstract Background Piezosurgery is an osteotomy system used in medical and dental surgery. Manystudies have proven clinical advantages of piezosurgery terms quality ofcut, maneuverability, ease use, safety. However, few investigations havetested its superiority over the traditional systems dynamicsof bone healing. Therefore, aim this study was to evaluate dynamics ofbone healing after osteotomies with compare them thoseassociated drilling. Methods One hundred ten rats were divided into two...

Various procedures have been proposed to treat gingival recession, but few studies compare these each other. The purpose of this study was evaluate a clinical comparison subepithelial connective tissue graft (SCTG) and guided regeneration (GTR) with collagen membrane in the treatment recessions humans.Twenty-four defects were treated 12 patients who presented canine or pre-molar Miller Class I and/or II bilateral recessions. Both treatments performed all patients, measurements obtained at...

Abstract Objective Inflammatory diseases often coincide with reduced bone mass. Mechanoresponsive osteocytes regulate mass by maintaining the balance between formation and resorption. Despite its biologic significance, effect of inflammation on osteocyte mechanoresponsiveness is not understood. To fill this gap, we investigated whether inflammatory cytokines tumor necrosis factor α (TNFα) interleukin‐1β (IL‐1β) modulate response to mechanical loading. Methods MLO‐Y4 were incubated TNFα...

BackgroundAlthough previous studies have shown the presence of Porphyromonas endodontalis in chronic periodontitis associated with periapical lesions, occurrence this pathogen diseased periodontal sites without lesions has been poorly investigated.ObjectiveThe aims study were to quantify P. patients evaluate potential correlation gingivalis and Tannerella forsythia, ability treatment reduce these pathogens.DesignPatients generalized selected by recording clinical attachment level (CAL),...

ABSTRACT Background: In the absence of autologous bone for harvesting, fresh‐frozen allografts turned into an alternative reconstruction procedures. Purpose: The purpose this study was to make a histological analysis onlay (ALs), compared with autografts, in patients who needed maxillary prior dental implants placement. Materials and Methods: Twelve deficiencies (width inferior 4 mm) sites where were planned enrolled study. From these, six elected be treated autogenous (AT) grafts AL. This...

Background: Smoking is a well‐known risk factor for destructive periodontal disease, but its relationship with status and subgingival microbiota remains unclear. Inherent limitations of microbiological methods previously used may partly explain these mixed results, real‐time polymerase chain reaction (PCR) has been presented as valid alternative. The aim the present study was to investigate clinical condition profile patients chronic periodontitis related habit smoking. Methods: Fifty (33 59...

ABSTRACT Background: Polymorphisms found in the IL‐1 family genes have been associated with susceptibility of periodontal disease. However, very little is known about relationship between polymorphisms on inflammatory mediators' and peri‐implant Purpose: The aim present study was to evaluate interleukin‐1β (IL‐1β) interleukin‐6 (IL‐6) concentration crevicular fluid, impact gene healthy diseased implants comparison teeth. Materials Methods: We examined 47 teeth patients grouped as: 31...

Halitosis has been correlated with the concentration of volatile sulfur compounds (VSC) produced in oral cavity by metabolic activity bacteria colonizing periodontal area and dorsum tongue. The aim this study was to determine whether there is some relationship between presence N-benzoyl-DL-arginine-2-napthylamide (BANA)-positive species Treponema denticola, Porphyromonas gingivalis, Bacteroides forsythus clinical malodor parameters.Twenty-one subjects (21 59 years old) probing depths (PD) >...

The aim of the present study was to evaluate effect strict supragingival plaque control on subgingival microbiota in smokers and never-smokers. Research into impact number bacteria has resulted contradictory findings. Real-time polymerase chain reaction (PCR) been suggested as a valid alternative current microbiologic methods based cultures.Forty-five subjects with chronic periodontitis were selected. Twenty-four them had never smoked, 21 active smokers. Four sites per patient selected for...

Background: Recently, the erbium‐doped:yttrium, aluminum, and garnet (Er:YAG) laser has been used for periodontal therapy. This study compared Er:YAG irradiation (100 mJ/pulse, 10 Hz, 12.9 J/cm 2 ) with or without conventional scaling root planing (SRP) to SRP only treatment of pockets affected chronic periodontitis. Methods: Twenty‐one subjects from 5 9 mm in non‐adjacent sites were studied. In a split‐mouth design, each site was randomly allocated group: (SRPL), (L), (SRP), no (C). The...

ABSTRACT Objectives: The aim of this study was to assess a suggested association between periodontitis and renal insufficiency by assaying kidney disease markers. Methods: Variables used diagnose were: (i) probing pocket depth (PPD), (ii) attachment loss (AL), (iii) bleeding on (BOP), (iv) plaque index (PI) (v) extent severity index. Blood urine were collected from 60 apparently healthy non-smokers (men women), consisting test group 30 subjects with (age 46±6 yrs) control 43±5 yrs). Kidney...

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a clinical condition characterized by presence exposed bone in maxillofacial region. Its pathogenesis still undetermined, but may be associated with risk factors such as rheumatoid arthritis (RA). The aim this paper to report two unpublished cases BRONJ patients RA and conduct literature review similar view describe main issues concerning these patients, including demographic characteristics therapeutic approaches applied. Two case...

Abstract Objectives The aim of this study was to evaluate the effect a hydrophilic surface on osseointegration in grafted areas with deproteinized bovine bone (DBB) and biphasic ceramics hydroxyapatite/β‐tricalcium phosphate (HA/TCP). Material methods Fifty‐six rats were randomly allocated four groups 14 animals each: DBB: DBB+Machined surface; HA/TCP: HA/TCP+Machined DBB‐H: DBB+Hydrophilic HA/TCP‐H: HA/TCP+Hydrophilic surface. defects performed at proximal epiphysis tibia. Then, filled...
