Acute dental abscess is a frequent and sometimes underestimated disease of the oral cavity. The acute usually occurs secondary to caries, trauma, or failed endodontic treatment. After intact pulp chamber opened, colonization root canals takes place with variable set anaerobic bacteria, which colonize walls necrotic forming specialized mixed biofilm. Asymptomatic necrosis common. However, formation when these bacteria their toxic products breach into periapical tissues through apical foramen...

To examine the distribution of bacteria into internal and external surfaces failed implants using histologic analysis.There were 10 pure titanium 5 hydroxyapatite-coated consecutively removed various years after their placement. Criteria for fixture removal peri-implant radiolucency clinical mobility. The mobile fixtures retrieved with patients under local anesthesia. Fixtures maintaining abutments aim to observe bacterial infiltration at level abutment/implant interface on implant surface.A...

Abstract Background Implant stability is commonly related to insertion torque. Recently, it has been suggested that higher torque may lead greater bone resorption. Purpose The aim of the present randomized clinical study was evaluate role different values in terms implant success, marginal loss, and facial soft tissues recession. Materials Methods Patients requiring a single dental were recruited receive one two implants with same macro‐geometry but cutting designs. First group consists 90...

Background: Genes involved in different biologic processes form complex interaction networks. However, only a few have high number of interactions with the other genes network. In previous bioinformatics and experimental studies concerning T lymphocyte cell cycle, these were identified termed “leader genes.” this work, human periodontitis tentatively ranked according to their obtain preliminary, broader view molecular mechanisms plan targeted experimentation. Methods: interrelated queries...

The purpose of the present study was to evaluate clinical efficacy placing implants in fresh extraction sites with simultaneous connective tissue grafting. teeth selected for this treatment showed gingival recession and/or absence attached gingiva.Ten patients (five men and five women), 42 55 years age, were included study. After initial examination planning, all underwent periodontal that deemed necessary favor wound healing. Subsequently, extracted, placed without reflection a...

Background: Immediate implant placement has several advantages, such as reduction in the number of surgical treatments and time between tooth extraction definitive prosthesis. However, there are still some situations that could jeopardize success aforesaid therapy, presence an infection caused by periodontal disease or periapical lesions. The aim this case series is to evaluate clinical implants placed fresh sockets showed signs disease. Methods: Thirteen patients (six males seven females,...

This study discussed a 3-year retrospective survey of clinical and esthetic outcomes immediate implants placed by experienced senior surgeons residents in implant dentistry.The chart review included patients who received single-tooth extraction placement at the Tuscan Stomatology Institute between 2009 2011. Treated independent postextraction areas were divided into two groups according to operator's experience: expert versus nonexpert group. Patient satisfaction with aspect, chewing,...

Periodontal infection may contribute to poor glycemic control and systemic inflammation in diabetic patients. The aim of the present study is evaluate efficacy non-surgical periodontal treatment patients by measuring oxidative stress outcomes.

Abstract Background Consistent bone changes occur after tooth removal, often compromising the success of implants placed within socket left to natural healing The long‐term effect ridge preservation on implant outcomes is still unclear. Purpose aim study was assess and survival rates in extraction sockets, with spontaneous healing, or grafted cortical porcine bone, collagenated corticocancellous bone. Materials methods Ninety patients need for a single premolar/molar an treatment were...

Periodontal diseases are characteristic for the excessive release of oxidant free-radicals by host. The aim present study was to evaluate efficacy an anti-oxidant-based formula containing propolis and herbs as adjunctive therapy standard non-surgical periodontal treatment (NSPT) when compared domiciliary use chlorhexidine-based formulae.Forty patients were enrolled in randomly allocated either a control (NSPT plus chlorhexidine gel formula) group or test anti-oxidant group. Clinical...

The healing process of the tooth extraction socket often leads to significant resorption alveolar bone, eventually causing clinical difficulties for future implant-supported rehabilitations. aim present animal study was evaluate bone remodeling after in a rabbit model, either with or without use plain collagen plug inside socket, by means micro-computed tomography. included micro-tomography analysis 36 rabbits’ incisor sockets, left empty filled plug. All animals were euthanized staggered...

The placement of implants immediately after tooth extraction has proven to be a predictable treatment strategy with very high success rate.The aim the present 7-year prospective single cohort study was evaluate rate, marginal bone level (MBL), soft tissue stability placed in fresh sockets and restored.This included 37 32 patients (19 females 13 males) an average age 40.1 ± 13.3 (range: 21-63 years) who received immediate unit restorations. Outcome evaluations were: implant failures,...

Patient-centered outcomes are being given great attention by the dental scientific community. The Oral Health Impact Profile -14 questionnaire (OHIP-14) has been introduced to address patients' success criteria when describing impact of oral rehabilitations on quality life (OHrQoL).Thirty-five patients wearing a full-arch implant-prosthesis in place between 4 and 6 years before this analysis were considered eligible then enrolled present retrospective study. According their prosthetic...

After tooth extraction, the alveolar bone tends to shrink in volume, especially on vestibular side. The role of myofibroblasts remodeling has not been sufficiently investigated. aim present study was explore gene expression related presence and activity during a 90-day healing period after extraction. included 36 rabbits, single extraction performed each rabbit. extractive sockets were randomly distributed natural or scarification wound. sacrifices staggered such manner that animals...

The aim of this study was to test a new collagen matrix (Mucoderm) positioned during oral implant abutment connection. A patient previously treated with Le Fort I for bone augmentation and 8 implants showing minimal amount keratinized tissue selected an extensive deepening the vestibule by apically positioning split palatal flap grafting Mucoderm. Clinical data at 9 14 days 1 2 months showed resorption graft, around implants, vestibule, morbidity reduced surgical treatment time. However,...
