introduction:mediastinum contains different vital structures that are located in the anterior and middle or posterior compartments. various types of mediastinal masses or tumors can be seen in the mediastinum. materials and methods:this case series study was performed on 95 patients who had referred to mashhad university of medical sciences between 1990 and 2010 were reviewed. the inclusion cri...

The primary goal of periodontal therapy is the removal of supra and subgingival bacterial deposits by mechanical debridement consisting in scaling and root-planing (SRP) using manual or power-driven instruments. The complete removal of bacteria and their toxins from periodontal pockets is not always achieved with conventional mechanical treatment. The use of lasers as an adjunctive therapy for ...

introduction: the efficiency of routine scaling and root planning is negatively influenced by the tooth anatomy and residual bacteria all possibly affecting the treatment outcomes in future. the present study compared the microbiologic effectiveness of the photodynamic therapy (pdt) as an adjunctive treatment modality for nonsurgical treatment in chronic periodontitis. methods: in this randomiz...

OBJECTIVES The aim was to answer three relevant questions: can systemic antimicrobials be efficacious if the biofilm is not disrupted? Can the type of debridement of the subgingival biofilm impact upon the clinical outcomes of the adjunctive antimicrobial therapy? Is the efficacy of the adjunctive systemic antimicrobial therapy dependent on the quality of the debridement of the subgingival biof...

PURPOSE The present study was performed to compare the treatment outcomes of non-surgical periodontal treatment according to the distribution of attachment loss of a given patient. METHODS Forty-five patients with moderate to severe periodontitis were divided in two subgroups; Group I patients with teeth manifesting attachment loss of ≥6 mm at one or more sites on the buccal/labial aspect whi...

This study aims to quantify and analyze the cost distribution of periodontal intervention that includes non-surgical surgical therapy in residual pockets management. Immediately after initial cause-related (ICRT), subjects were allocated into two treatment groups: (NS) or (S) therapy. Clinical data recorded at baseline (Phase I) review II). Direct indirect estimated from patients' perspective R...

BACKGROUND AND OBJECTIVE Prospective studies that investigated the influence of surgical and nonsurgical procedures in the recurrence of periodontitis and tooth loss in periodontal maintenance therapy (PMT) programs have not been previously reported. The objective of this study was to evaluate longitudinally the recurrence of periodontitis in regular compliers (RC) and irregular compliers (IC) ...
