Assessment of periodontal health status in patients with Parkinson's disease-A systematic review and meta-analysis of cross-sectional studies.

Introduction: Parkinson's disease (PKD) is neurodegenerative disorder marked by tremors, bradykinesia, muscle rigidity and reduction in precise hand movements which could lead to improper oral hygiene and Periodontal disease. Current systematic review aims to review existing literature and provide assessment of periodontal health in PKD patients through a meta-analysis METHODS: Review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and registered in PROSPERO-CRD42023451700. Databases were searched for studies having sufficient data on periodontal health in patients with PKD compared to healthy controls and reporting outcomes in terms of various periodontal parameters of probing depth (PD), plaque index (PI), clinical attachment level (CAL), presence of bleeding on probing and gingivitis.

Porous polymer film formation by water droplet templating using polystyrene.

Studies show that the formation of breath figures over polystyrene is not clearly understood-sometimes the patterns are regular and sometimes they are barely formed. In an attempt to understand this process a little more, breath figures over polystyrene of three molecular weights and on the smooth and grooved DVD surfaces are prepared and studied. The microporous films are prepared by the evaporation of the chloroform solution of the polymers in a humid environment.

Assessment of anterior malar projection using visual photographs and lateral cephalograms: A comparative study.

Background: The association between maxillary development and vector relationships is used in the field of plastic surgery, but the validity of this principle has not been tested yet.

Aim: The aim of this study is to determine whether visual classification of anterior malar projection using vector relationships is supported by cephalometric analysis.

Materials And Methods: Normal, healthy 40 subjects aged 10-15 years with no history of orthodontic treatment, craniofacial syndromes, or trauma formed the study group.
