All endodontic canals were filled using gutta percha cones using the cold lateral condensation technique in combination using one of the mentioned sealers ( n  = 20 per group)...

AIM: To describe a clinical case of ultrasound (US) used to evaluate, before, post-immediately, and after 4 months, the facial application of a volumizing and biostimulating substance. BACKGROUND: Detecting the behavior of injected filler materials with high-frequency US-guided application is the future of natural facial rejuvenation with more predictable and satisfactory results. TECHNIQUE: A patient indicated for orofacial harmonization (OFH) procedures through volumizing and biostimulating material application was invited to participate...

AIM: This study aimed to evaluate the marginal microleakage and maximum occlusal fracture loads and fracture modes of two novel class II preparation designs, "infinity edge" and the "2.5 mm cusp reduction" preparations as compared to a traditional class II preparation without cuspal involvement. MATERIALS AND METHODS: Thirty extracted human mandibular molars were prepared for moderate-sized class II restorations with extensions into all occlusal grooves. Of these, ten class II preparations served as control...

AIM: To evaluate and compare the fracture toughness and flexural strength of four different core build-up materials. MATERIALS AND METHODS: A total of 60 samples were divided into four groups ( n = 15) group I: dual cure composite resin reinforced with zirconia particles (Luxacore Z), group II: light cure composite resin (Lumiglass DeepCure), group III: zirconia reinforced glass ionomer cement (GIC) (Zirconomer Improved), and group IV: chemically cure composite resin (Self Comp) respectively...

AIM: To compare oral hygiene (OH) differences during verbal or video OH instructions with or without images displaying poor oral health consequences. MATERIALS AND METHODS: Twenty-one healthy females (18-30 years) were randomly and equally divided into three intervention OH instruction groups: (1) verbal, (2) video-based, (3) video-based with image displaying the consequences of poor OH. Gingival bleeding on probing (BOP), gingival bleeding index (BI), and plaque score (PS) were assessed at baseline and after 4 weeks...

AIM: To evaluate the intensity of postendodontic pain (PEP) using final irrigation with side-vented needle (SV), EndoActivator (EA), and Ultra X (UX) in single-visit endodontics (SVE) with F-One rotary files. MATERIALS AND METHODS: A total 150 patients indicated for endodontic treatment were selected. Single-visit endodontics treatment was performed under local anesthesia. For the final irrigation protocol, they were divided into three groups: group I (SV), group II (EA), and group III (UX)...

AIM: This study aimed to explain the potential factors of dental and oral hygiene behavior as a predictor of dental caries status in children with visual impairments. MATERIALS AND METHODS: The prevalence of dental caries in visually impaired children was investigated through a cross-senal study conducted at a visually impaired special needs elementary school in Jakarta, Indonesia. The study included 25 visually impaired children aged 6-12 years, with dental caries status examined using the decayed, missing, and filled teeth (DMFT)/dmft index according to World Health Organization (WHO) criteria...
