BACKGROUND The deleterious effects of chewing betel quid (BQ) with or without tobacco on periodontal health are poorly addressed. The aim of this study was to investigate the severity and extent of periodontal disease among individuals chewing BQ with and without tobacco. METHODS One hundred twenty individuals (70 BQ chewers: 35 with tobacco and 35 without tobacco) and 50 control individuals ...

OBJECTIVES To evaluate the effect of hyperbaric oxygen therapy (HBO2) as an adjunct to scaling and root planing (SRP) in the treatment of severe cases of chronic periodontitis. MATERIALS AND METHODS In 20 patients diagnosed with severe generalized chronic periodontitis (pockets>7mm) with bleeding on probing, SRP was rendered in all pockets. Additionally, five consecutive hyperbaric sessions w...

Salivary flow rate, immunoglobulin, and periodontal status were affected during a simulated Skylab mission. The effect is more prominent after long-duration space flights and can persist for several weeks after landing. The objective of this study was to determine the effect of a simulated Mars environment on periodontal status and levels of salivary microorganisms and immunoglobulins in the hu...

The purpose of the present case report was to describe the surgical treatment of a peri-implantitis lesion associated with a regenerative approach. A 48-year-old patient came to authors' attention 36 months after the placement of a dental implant (ITI-Bonefit Straumann, Waldenburg, Switzerland) in position 46. A swelling of the peri-implant soft tissues was observed, associated with bleeding on...

At present, there are no diagnostic tools that permit early detection of peri-implantitis. The purpose of this cross-sectional study was to evaluate the correlation of aspartate aminotransferase (AST) levels with traditional periodontal clinical parameters around dental implants, since AST has been associated with destruction of cardiac, hepatic, and periodontal tissues. Twenty healthy voluntee...

OBJECTIVE To compare the periodontal health of maxillary and mandibular anterior teeth retained with two types of fixed retainers. MATERIALS AND METHODS A fixed straight retainer (SR) group had 39 subjects, and a fixed wave retainer (WR) group had 35 subjects. Subjects were between the ages of 13 and 22 years and had been in fixed retention for 2 to 4 years. Pocket probing depths, bleeding on...

Background and aims. Only half to two-thirds of cardiovascular diseases can be explained by the classic risk factors. It is believed that chronic oral inflammation is a potent risk factor for systemic diseases. Studies show that electrocardiogram ST segment changes can be predictive of myocardial infarction outcome. In this study the relation between electrocardio-gram ST segment changes and or...

background and aims. the aim of this study was to compare the effectiveness of adjunctive photodynamic therapy (pdt) in the treatment of aggressive periodontitis. materials and methods. a total of 24 patients with clinical diagnosis of aggressive periodontitis received scaling and root planing (srp) for periodontal treatment. in a split-mouth design study, the teeth of one quadrant of each arch...

Subgingival margins are often required for biologic, mechanical, or esthetic reasons. Several investigations have demonstrated that their use is associated with adverse periodontal reactions, such as inflammation or recession. The purpose of this prospective randomized clinical study was to determine if two different subgingival margin designs influence the periodontal parameters and patient pe...
