Constrained independent component analysis (CICA) is capable of eliminating the order ambiguity that is found in the standard ICA and extracting the desired independent components by incorporating prior information into the ICA contrast function. However, the current CICA method produces constraints that are based on only one type of prior information (temporal/spatial), which may increase the ...

Maxillary premolars exhibit variable root canal morphology, but it is quite rare to find three canals in their root system. The aim of this case report is to present the diagnosis and clinical management of a patient with anatomical variation of having three root canals in the maxillary first premolar. Three-canalled maxillary premolars are quite an endodontic challenge. A discussion is provide...

Periapical lesions of endodontic origin may develop asymptomatically and become extensive. Treatment options to manage such lesions range from non-surgical root canal treatment and/or apical surgery to extraction. A high percentage of complete and partial healing of extensive perapical lesions following conventional endodontic therapy has been reported. The case reports in this article describe...

THE pressure relationships in the anterior chamber, the canal of Schlemm, and the episcleral venous plexus are of obvious importance to the understanding of the drainage of aqueous humour. Episcleral venous pressures have been estimated by several workers (Thomassen, 1947 ; Linner, 1954 ; Bain, 1954), but so far no direct measurements of the pressure in the canal of Schlemm have been attempted....

Biofilms and microbial aggregates are the common mechanisms for the survival of bacteria in nature. In other words, the ability to form biofilms has been regarded as a virulence factor. Microbial biofilms play an essential role in several infectious diseases such as pulp and periradicular pathosis. The aim of this article was to review the adaptation mechanisms of biofilms, their roles in pulpa...

Objective. The study was to evaluate impacted mandibular third molars (IM3M) for their angulation, level of eruption, third molar space and relation of inferior alveolar canal with their roots. Methods. Total 988 IM3M were studied in 578 individuals of age 18 years and above, dividing them into three groups i.e. symptomatic, asymptomatic and radiographic only. Individuals were also divided acco...

Objective: The purpose of this research was to evaluate the effectiveness various root canal sealers in reducing postoperative pain and need for analgesics. Methods: asymptomatic necrosis apical periodontitis 60 single-rooted teeth were studied by randomly assigning them 2experimental groups (n=30) according sealer: AH Plus MTA Fillapex. Two appointments needed complete endodontic treatment, ca...

Introduction: Endodontic therapy aims at shaping, cleaning, and disinfecting the root canal, being performed by removing all pulp tissue or necrotic remains microorganisms present in canal system. Among substances proposed as a delay dressing endodontic treatment of teeth with chronic periapical reaction, calcium hydroxide stands out. Objective: It was to demonstrate, through comprehensive revi...
