Specific staining of the extracellular matrix components is especially helpful in studying tissue remodeling, particularly case connective pathologies. As developed by Junqueira and colleagues 1979, specific Picrosirius red one most important stains to study collagen networks different tissues. Under polarized light, bundles appear green, or yellow, are easily differentiated from black background, thus allowing for quantitative morphometric analysis. point out, many studies use color...

The respective abilities of the GOHAI and OHIP-14 to discriminate between aged patients with different levels oral diseases have rarely been studied in developing countries. aim this study was compare discriminative an elderly Lebanese population, particularly identify persons masticatory function.

Direct sinus procedure performed 22 patients intended for implant placement. Two types were used (Bio-Oss Cerabone) after 8 months healing time implants inserted. Radiographic assessment over period four years. Particle size, calcium release, size type crystal structure each evaluated. Results. average particle Bio-Oss (1 mm) much smaller...

To determine if resonance frequency analysis (RFA) correlated with insertion torque (IT), bone volume (BV), and clinical osseointegration at 6 weeks.For 18 patients, BV was evaluated histologically by retrieving core biopsies before placement of 40 dental implants. Peak IT recorded implant placement, RFA values (implant stability quotient [ISQ]) were noted baseline, 3 weeks, weeks. Osseointegration weeks when torquing abutments to 30 N. ISQ IT, abutment results. Data statistically...

Buccal measured at 4, 6, 8, 10 mm apical cement-enamel junction (CEJ).At 4 from CEJ, mean buccal 1.0 it decreased gradually significantly in direction (6, mm). A thin associated with a labial plate half...

To radiographically monitor sinus membrane swelling after lateral floor elevation surgery at short and long healing periods.For 26 patients seeking posterior maxillary implant-supported reconstruction, 32 elevations were performed using Piezosurgery. Sinus membranes grafted synthetic calcium phosphate bone substitutes, graft volume was measured in cubic centimeters for each case. Cone beam computed tomography (CBCT) examination conducted preoperatively all 1 day (n = 8), 2 days 9), 3 or 7 7)...

Abstract The purpose of this study was to investigate the relationship between osteoblastic cells behavior and biotribocorrosion phenomena on bioactive titanium (Ti). Ti substrates submitted anodic oxidation etching treatments were cultured up 28 days with MG63 osteoblast‐like cells. Important parameters in vitro bone‐like tissue formation assessed. Although no major differences observed surfaces topography (both rough) wettability hydrophobic), a significant increase cell attachment...

Root resection and hemisection is a well-documented treatment option for extending the life span of furcated molars. The aim present study was to retrospectively evaluate long-term results root 195 patients with up 40 years follow-up. Records who had undergone or were reviewed. A minimum follow-up 5 needed. molar recorded as survival if it still functional without any signs discomfort, pain, pathology from restorative, endodontic, periodontal points view. Ninety-eight excluded not...

Introduction: The aim of this study was to evaluate the prevalence musculoskeletal disorders and identify their associated factors among a group Lebanese dentists. Materials Methods: A total 314 Lebanese, dentists completed an anonymous questionnaire that focused on occupational health problems. This approved by ethics committee Saint-Joseph University Beirut, Lebanon. statistical analyses were performed using SPSS for windows. alpha error set 0.05. Results: mean age participants 39.2...

The aim of the present study was to evaluate bone formation after maxillary sinus augmentation using bovine substitute material Bio-Oss alone by means clinical, histological, and histomorphometrical examination human biopsies. Deproteinized (DPBB, Bio-Oss) used fill cavities elevation mucosa following major pneumatization. Twenty patients with edentulous posterior maxillae were treated 20 procedures a 2-stage technique. Residual lateral height less than 3 mm. Forty-nine Straumann endosseous...

Primary stability is evaluated using resonance frequency analysis (RFA) and insertion torque (IT). Although there a strong correlation between RFA IT, studies failed to find bone implant contact (BIC) or IT BIC.To compare RFA, BIC of SLA, SLActive, Euroteknika, TiUnite surfaces evaluate the them.Thirty-two implants were placed in 8 sheep. recorded. Animals killed at 1 2 months.A significant difference was found 4 surfaces. No for IT. Mean different all A positive with SLA. months.Implants...

To compare prospectively the effect of different insertion torques (ITs) on marginal bone stability and study soft-tissue buccal thickness as confounding factors while using a 3-dimensional radiographic evaluation.Thirty-nine implants were placed in 22 patients. IT, thickness, recorded at implant placement. Marginal loss was evaluated individualized periapical radiographs cone-beam computed tomography 1 year after loading.Three groups emerged based their IT: group I (<30 Ncm), II (between...

Bone substitutes alone or supplemented with platelet-derived concentrates are widely used to promote bone regeneration but their potency remains controversial. The aim of this study was, therefore, compare the regenerative potential preparations containing autologous platelet lysate (APL) and particles either deproteinized bovine mineral (DBBM) biphasic calcium phosphate (BCP), two different resorption patterns. Rabbit APL was prepared by freeze-thawing a suspension. Critical-size defects in...

Clinically evaluate implants placed after ultrasonic implant site preparation (UISP) and standard drilling (SD).Ten patients received 21 using UISP (n = 11) or SD 10). Bone quality was hand assessed final insertion torque (IT), resonance frequency analysis (ISQ) at baseline ISQ, removal values (RTV) 4 weeks were recorded compared.Mean IT 70.91 72.40 N/cm in groups, respectively, not statistically different. significantly correlated to bone quality. Mean ISQ different 74.72 74.73 for 76.70...

Dentistry is a well-respected healthcare profession in Arab countries. An increase the number of applicants led to students seeking dental education abroad and, lately, establishments dozens private schools, whereas had traditionally been public, with subsidised tuition fees. Dental educators have therefore faced challenges maintaining standards and ensuring appropriate oral provision.

Background: This case report discusses the treatment of an iatrogenic periodontal defect caused by inadequate orthodontic appliance in a 9‐year‐old girl . Methods: The multidisciplinary approach to this consisted using bone grafting technique restore 10 mm dehiscence. Three months later was initiated straighten and level central incisors. Six mucogingival surgery performed cover 2 3 gingival recession Results: bony defects were completely filled dehiscence reduced 4 mm. connective tissue...

Heparan sulfate glycosaminoglycans are key players of tissue repair and can be regarded as useful compounds for regenerative medicines. Unfortunately, their therapeutic uses face many technical, industrial, regulatory hurdles due to animal origin. So, some non-animal sulfated polysaccharides mimic heparan properties offer interesting solutions replace them. Among them, dextran derivatives, seaweed polysaccharides, or marine bacterial the best known have demonstrated pro-regenerative...
