The gum resin exuding from the leaf buds of Gardenia gummifera was investigated. Eight new cycloartane triterpenes, 1-6, 8, and 10, together with two known triterpenes, 25-hydroxycycloart-23-en-3-one (7) and cycloartenone (9), were isolated and identified by extensive NMR spectroscopy. For cycloartenone (9), full NMR assignments are given as these data were not available in the literature. Eight compounds possess a C(3)=O group, two are 3,4-secocycloartanes bearing a free C(3)OOH group; in one of the cycloartanes, gummiferartane-9 (10), ring A occurs as a seven-membered lactone.

Statement Of Problem: Staining at the gingival margin could impact denture longevity, but the behavior of gingival colored composite resins (GCCs) in this area remains unclear.
Purpose: This in vitro study evaluated surface staining, microleakage, and push-out bond strength at the gingival margin of artificial teeth, comparing two consistencies of GCCs with two resin base materials.
Material And Methods: Specimens included artificial teeth (Ivostar; Ivoclar AG) and two acrylic resin base materials: conventional (Ondacryl; Clássico) and high-impact (Diamond D; Keystone Industries) (n=300).

Background: Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non-carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics. There is limited evidence regarding tunnel-based procedures combined with connective tissue grafts (CTGs) for treating recession-associated NCCLs.
