Overinstrumentation during root canal treatment is one of the causes for iatrogenic enlargement of the root apex. It also leads to unwarranted coronal third widening, which results in thinning of the dentinal walls and makes the tooth susceptible to fracture. Another difficulty arises during control of obturation material within the canal. Such cases can be managed with obturation using mineral...

New and innovative surgical techniques are necessary to help the clinician ensure the best results and satisfy patient's expectations. One such periodontal problem that has been challenging to the dental practitioners and impacts the oral health quality of life of patients has been gingival recession. When present anteriorly where esthetics is a major concern, patient centric parameters too bec...

Self-assembled monolayers (SAMs) of octanethiol and benzeneethanethiol were deposited on clean Pt(111) surfaces in ultrahigh vacuum (UHV). Highly resolved images of these SAMs produced by an in situ scanning tunneling microscope (STM) showed that both systems organize into a super-structure mosaic of domains of locally ordered, closely packed molecules. Analysis of the STM images indicated a (s...

Amidst several controversies involving orthodontic treatment and gingival recession, periodontal complications of tongue thrust habit especially in adults have not yet been fully investigated. This case report presents a successful clinical case of progressive spacing of incisors (PSI) with gingival recession treated with proper alveolar root housing and autogenous grafting. A 24 year old girl ...

The objective of this literature review was to critically review the evidence available in the literature regarding the expediency of erbium family of lasers for root bio modification as a part of periodontal therapy. The literature search was performed on the Pubmed using MeSH words such as "lasers/therapeutic use, scaling, dental calculus, tooth root/anatomy and histology, ultrasonic therapy"...

Background: Gingival recession is a condition where the root surface of tooth exposed due to migration gingival margin and junctional epithelium in an apical direction. The problem that patients often complain about aesthetic problem, especially if occurs upper anterior teeth. In addition, can also cause dentine hypersensitivity exposure was previously covered by gingiva. One treatment options ...

In case-based reasoning (CBR) there are compelling arguments in support of large case-bases; greater target problem coverage, better solution quality, improved system efficiency. However a problem known as the utility problem dictates that the last of these arguments is not necessarily true. In fact, adding more cases to an already "saturated" case-base will reduce rather than improve system ef...
