Herpes simplex virus infection: Management of primary oral lesions in children.

Primary herpetic gingivostomatitis (PHGS) represents the most observed clinical feature of primary herpes infection with the simplex virus (HSV). It is often caused by HSV-1 and affects children most of the time. Unlike, the majority of primary HSV infections that is asymptomatic.

Epidermoid cyst of the buccal mucosa-An uncommon entity: Case report and literature review.

Epidermoid cyst of the buccal mucosa is rare. Nevertheless, it must be included in the differential diagnosis of swelling in this area. The diagnosis is based on anatomopathological examination.

[The role of piezosurgery in the treatment of a rare case of superinfected cemento-osseous dysplasia caused by actinomyces: a case report].

Cemento-osseous dysplasia is a benign fibro-osseous lesion affecting the alveolar bone. It is classified into three forms: periapical, focal or florid dysplasia. It is often asymptomatic and fortuitously discovered during a routine radiological examination.

Mucosal coronally positioned flap technique for management of excessive gingival display.

Improvement of smile esthetics is a major goal of modern dentistry. Various treatment modalities have been proposed to correct excessive gingival display, depending on intraoral or extraoral etiologies. This report aimed to document the use of mucosal coronally positioned flap called surgical lip repositioning technique for the management of a gummy smile associated with vertical maxillary excess.

Piezoelectric-Assisted Removal of a Mandibular Cementoossifying Fibroma: An Innovative Technique.

Diagnosis of cementoossifying fibroma is oriented by the clinical and radiological aspects of the lesion. Histology confirms the diagnosis. Treatment is surgical with enucleation-resection depending on the lesion size or wider resection with bone reconstruction in cases of large fibromas.

Gingival Melanin Depigmentation by 808 nm Diode Laser: Report of a Case.

Gingival hyperpigmentation frequently poses an aesthetic problem, especially in patients with gingival smile. This paper presents the use of a 808 nm pulsed diode laser for gingival depigmentation in a 22-year-old male patient, with a frequency of 20,000 Hz, a peak power of 5 W, and a pulse width of 26 microseconds, using a 400 nm flexible optic fiber. The hyperpigmented gingival tissue was removed without bleeding or postoperative pain.

Antioxidant and antiproliferative potential of biosurfactants isolated from Lactobacillus casei and their anti-biofilm effect in oral Staphylococcus aureus strains.

Biosurfactants also called bioemulsifiers are amphipathic compounds produced by many microorganisms that allow them to exhibit a wide range of biological activities. The aim of this study was to determine the antioxidant and antiproliferative potential of biosurfactants isolated from Lactobacillus casei and to assess their anti-adhesive and anti-biofilm abilities against oral opportunistic Staphylococcus aureus strains. The antioxidant activity of biosurfactant was evaluated using the in vitro scavenging ability on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical.

Cone-beam computed tomography exploration and surgical management of palatal, inverted, and impacted mesiodens.

Supernumerary teeth are extra teeth or toothlike structures which may have either erupted or unerupted in addition to the 20 deciduous teeth and the 32 permanent teeth. Mesiodens is one of these located in the midline between the two central incisors. Their presence may give rise to a variety of clinical problems.

Assessment of adhesion, invasion and cytotoxicity potential of oral Staphylococcus aureus strains.

The oral cavity is regarded as a relevant site for Staphylococcus aureus colonization. However, characterization of virulence mechanisms of oral S. aureus remains to be uncovered.

Adhesive properties and extracellular enzymatic activity of Staphylococcus aureus strains isolated from oral cavity.

Staphylococcus aureus is one of prominent bacterial pathogen that occurs in oral region. In this study, 21 strains of S. aureus isolated from the oral cavity of Tunisian patients were investigated for slime production using Congo red agar method (CRA) and adherence assay.

Molecular detection of bacteria associated to dental caries in 4-12-year-old Tunisian children.

The occurrence of several microbial species in the oral cavity of 4-12-year-old Tunisian children was investigated. Samples were taken from 158 children (81 caries actives and 77 caries free). Genomic DNA was extracted and analyzed for the presence of 17 microbial species using a polymerase chain reaction assay.

Antibiotic resistance and adhesion properties of oral Enterococci associated to dental caries.

Background: Enterococci are increasingly associated with opportunistic infections in Humans but the role of the oral cavity as a reservoir for this species is unclear. This study aimed to explore the carriage rate of Enterococci in the oral cavity of Tunisian children and their antimicrobial susceptibility to a broad range of antibiotics together with their adherence ability to abiotic and biotic surfaces.

Results: In this study, 17 E.

Molecular investigation of macrolide and Tetracycline resistances in oral bacteria isolated from Tunisian children.

Objective: This study aims to investigate the antibiotic susceptibility of strains isolated from the oral cavity of Tunisian children.

Design: Strains were isolated from the oral cavity of Tunisian children (60 caries-actives and 30 caries-free). Molecular characterization was assessed by PCR assay to detect erythromycin methylase gene (ermB), macrolide efflux (mefI) and tetracycline resistance genes (tetM and tetO).

Cell surface hydrophobicity, biofilm formation, adhesives properties and molecular detection of adhesins genes in Staphylococcus aureus associated to dental caries.

Staphylococcus aureus is an important pathogen that forms biofilm. In this study, 22 S. aureus have been isolated from the oral cavity of Tunisian children and investigated for slime production using Congo red agar method (CRA) and semi quantitative adherence assay.

Adhesive properties and hydrolytic enzymes of oral Candida albicans strains.

Several virulence factors in Candida albicans strains such as production of hydrolytic enzymes and biofilm formation on surfaces and cells can contribute to their pathogenicity. For this, control of this opportunistic yeast is one of the factors reducing the nosocomial infection. The aim of this study was to investigate biofilm formation on polystyrene and polymethylmethacrylate and the production of hydrolytic enzymes in Candida albicans strains isolated from the oral cavity of patients suffering from denture stomatitis.
