Periodontal disease is one of the most prevalent afflictions
affecting the human beings. When occurs, it destroys the tooth
supporting structures like periodontal ligament, cementum and
alveolar bone. If untreated, tooth may become mobile and finally
may get exfoliated. The ultimate goal of periodontal therapy is
creation of an environment that is conducive to maintaining the
patient's dentition in health, comfort and function. Periodontal
therapy is directed not only at inflammation control but also at
pocket reduction and associated bone defect. The shift in
therapeutic concepts from resection to regeneration has
significantly impacted the practice of periodontology. Regeneration
of lost bone and periodontal attachment improves the support of the
tooth and its prognosis. Bone replacement grafts have been shown to
produce greater clinical bone defect fill from flap debridement
alone. In most of the clinical studies, the osseous grafted sites
have outperformed the non grafted sites in the regeneration of the
lost periodontal structures. This research work evaluated the
efficacy of -tricalcium phosphate plus hydroxyapatite in the
treatment of periodontal infrabony defects."
One of the important goals of periodontal therapy is the
restoration of the lost periodontium and conversion of the
periodontitis affected root surface into a substrate, which is
biologically hospitable for epithelial and connective tissue cell
adherence and attachment. An objective of periodontal treatment is
the predictable regeneration of the periodontium in areas
previously affected by periodontal disease. Periodontitis affected
root surfaces show many changes and the root is commonly referred
to as 'pathologically exposed'. The traditional treatment of
pathologically altered root surfaces has relied on mechanical
removal of plaque and calculus, root bound toxins and contaminated
cementum. It is not possible to decontaminate a periodontitis
affected root surface completely by mechanical means alone. The
instrumented surface will inevitably be covered by a smear layer
which is usually comprised of remnants of dental calculus, necrosed
root cementum, flecks of hydroxyapatite crystals, microorganisms
and their products. The root surface serves as a wound margin
during regeneration so it is necessary to rehabilitate the root
surface for cell attachment and fiber insertion.
Establishing the identity of a person may seem like an easy task;
the person, or their friends or family, can simply be asked their
name. In medicolegal cases, however, there are often reasons why
people are either unable to give accurate answers or purposefully
give inaccurate ones. In cases of death, a body may also be too
disfigured due to trauma to allow for easy identification. Though
sometimes difficult, identification remains a necessary task.
Identification of an individual can be confirmed by several
different methods. However when the number of victims increases,
the forensic experts have to depend on more specific extensive
information and at this point the dental tissues become an
encyclopedia of information. Through this book, author aims to draw
the attention that these methods cannot always be used, sometimes
simple techniques can be used successfully in human identification,
such as "Palatal rugoscopy." Palatoscopy is a name given to the
study of palatal rugae in order to establish a person's identity as
no two palates are alike and palatal rugae appear to possess the
features of ideal identification parameters - uniqueness,
individuality and stability.
Local drug delivery has gained wide acceptance as an adjunct to
mechanical debridement for the treatment of chronic periodontitis.
A variety of delivery vehicles have been utilized for intrapocket
administration of antimicrobial agents with variable success.
Varnishes, which accomplish a reservoir of drug on the tooth
surface are one of the recently developed vehicles used to deliver
antimicrobial agent such as chlorhexidine, being utilized for the
treatment of periodontitis. They allow application of a sufficient
dose of antimicrobial agent over a longer period of time. So,
varnishes seem to be an appealing vehicle for delivery of
chlorhexidine (a gold standard anti-plaque agent) in periodontal
milieu. From the results of present investigation, it can be
concluded, within limitations of the study, that multiple
applications of 1% chlorhexidine varnish have an added benefit over
single application in treatment of chronic periodontitis.
