Aesthetic perceptions and psychosocial impact of malocclusion: comparison between cleft and non-cleft patients and their parents.

Objective: To evaluate the influence of dentofacial attractiveness using the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ), Satisfaction with Life Scale (SWLS) and Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) in patients with cleft lip/palate (CLP), and non-cleft orthodontic patients (Non-CLP) and their parents.

Materials And Methods: Eighty patients (aged 11-19 years) comprising 40 CLP and 40 non-CLP were administered the PIDAQ and SWLS questionnaires to be rated individually by the patients, along with IOTN-AC rated by the patients and their parents, respectively. The subjects were also sub-divided according to their age, i.

Association of Genetic Polymorphisms in the VKORC1 and CYP2C9 Genes with Warfarin Dosage in a Group of Kuwaiti Individuals.

Background And Objective: Warfarin is the most widely prescribed oral anticoagulant worldwide. The narrow therapeutic index and the large variation in the inter-individual dose of warfarin are problematic, since the side effects can be lethal. Single nucleotide polymorphisms (SNP) in CYP2C9 and VKORC1 have been shown to significantly affect warfarin dosage toleration and this effect varies among different populations.

Establishment of a new relationship between posed smile width and lower facial height: A cross-sectional study.

Objective: The present study is intended to add a new parameter that would be useful in orthodontic clinical evaluation, treatment planning, and determination of vertical dimension (at occlusion).

Materials And Methods: Standardized videographic recording of 79 subjects during posed smile was captured. Each video was then cut into 30 photos using the free studio software.

In vitro evaluation of different methods of ligation on friction in sliding mechanics.

Aim: The aim of this study was to evaluate the effect of different methods of ligation in tie configurations on friction in dry and wet conditions.

Methods: Four methods of ligations were used: regular round tie, figure eight, twist, and diagonal. Materials used were Alastik (3M Unitek), Power O module (ORMCO), O-ring ligatures (JES), stainless steel ligatures (TP Orthodontics), 0.

Risk assessment for periodontal disease.

The prevention and treatment of periodontal disease is based on accurate diagnosis, reduction or elimination of causative agents, risk management and correction of the harmful effects of the disease. The practice of risk assessment involves dental care providers identifying patients and populations at increased risk of developing periodontal disease. This can have a significant impact on clinical decision making.

Antimicrobial photodynamic therapy: An overview.

Inflammatory periodontal disease caused by dental plaque is characterized by the clinical signs of inflammation and loss of periodontal tissue support. The mechanical removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have been the conventional methods of periodontal therapy. But the removal of plaque and the reduction in the number of infectious organisms can be impaired in sites with difficult access.
