The force applied by the orthodontist to facilitate orderly movement of teeth their new position may have deleterious effects on most important structure involved in procedure—the periodontium. This chapter endeavors provide an overview biological processes that play a role achieving patient’s as well orthodontist’s objective.

Introduction: Periodontal disease, an inflamma- tory and infectious disease in adults and anemia associated with chronic infection, is one of the most common types of anemia. Considering the similarity of pathogens causing periodontal dis‌ease and anemia, this study aims to investigate the correlation between hematologic para‌meters associated with anemia and modera‌te chronic periodontitis. &...

statement of the problem : fixed retainers were developed to maintain incisor alignments after orthodontic treatments. although the effects of fixed retainers on periodontal health are clinically studied, no studies have still evaluated the histological changes in the periodontium after the placement of thefixed retainers. purpose: the aim of this study was to evaluate the effects of customised...

Periodontal disease in Down's syndrome (DS) population seems to be a more common and serious problem than caries. The aim of this study was to assess the state of periodontal structures in patients with DS. The Community Periodontal Index of Treatment Needs was used for periodontal status assessment in 71 DS subjects aged 9-34 years. A control group consisted of 71 age- and sex-matched healthy ...

The periodontium, which is responsible for the retention of teeth in the maxilla and mandible, consists of four tissue types. Cementum and alveolar bone are the hard tissues to which the fibrous periodontal ligament anchors the tooth into the skeleton, and the gingiva is the covering tissue of the periodontium (Fig. 42.1). The gingiva is a unique body tissue in that it allows the penetration of...

Introduction:There are conflicting reports on the effects of surgical removal of impacted mandibular third molars on the periodontium of the adjacent teeth. The aim of this study was to compare the condition of the periodontium six months after extraction of impacted mandibular third molars with baseline values. Methods: Fifty patients with mesioangular impacted mandibular third molarsparticipa...

OBJECTIVES Sex hormones have long been considered to play an influential role on periodontal tissues, bone turnover rate, wound healing and periodontal disease progression. The objectives of this review article are to (1) address the link between sex hormones and the periodontium, (2) analyse how these hormones influence the periodontium at different life times and (3) discuss the effects of ho...
