PeriodonticsSubgingival scaling and root planing (SRP) is a non-surgical procedure used to treat periodontal disease by removing plaque and calculus from below the gum line. The procedure significantly alters the microflora of the periodontal pocket. It shifts the microbial composition from a predominantly anaerobic, gram-negative population associated with disease to a microflora with a higher proportion of aerobic, gram-positive bacteria, which is indicative of periodontal health. This change is a primary goal of the treatment, as the reduction of pathogenic bacteria helps to reduce inflammation and infection.

Oral PathologySystemic sclerosis (scleroderma) causes contracture of facial skin giving a masklike appearance due to excessive collagen deposition and skin tightening. This leads to loss of facial expressions and a characteristic "pinched" facial appearance with microstomia and radial furrows around the mouth. Craniofacial dysostosis, achondroplasia, and solar elastosis do not cause this specific masklike facial contracture.

ProsthodonticsThe lingual bar has a half-pear shape with the broadest portion at the inferior border. This design provides maximum strength and rigidity in the lower portion while maintaining a smooth, rounded superior border that is comfortable for the tongue. The bulk is placed inferiorly where it is less intrusive to tongue function.
