Composites, cements, root canal procedures
Bis-GMA = most common resin matrix. Hybrid = best overall. Microfill = best polish. Nanofill = latest. Depth of cure = 2mm per increment. C-factor = bonded/unbonded surfaces.
Total etch = 4th & 5th gen (gold standard). Self-etch = 6th & 7th gen. 5th gen one bottle = most popular. 7th gen = all-in-one. Etch & rinse still best for enamel.
Chemical bond to tooth. Fluoride release. Resin-modified GIC = improved strength. Type I = luting. Type II = restorative. Type III = liner. Biocompatible = no pulp irritation.
Maxillary molar = triangular access. Mandibular molar = trapezoidal. Most common extra canal = MB2 (maxillary molars). Lower incisors = often 2 canals.
Apex locator = most accurate. Working length = 0.5-1mm short of radiographic apex. Crown-down technique = most popular. ProTaper sequence: S1→S2→F1→F2→F3.
NaOCl = most commonly used irrigant (dissolves organic). EDTA = removes smear layer (inorganic). CHX = substantivity. Ca(OH)2 = most popular intracanal medicament.
Lateral condensation = gold standard. Warm vertical = Schilder technique. Gutta percha = most common core material. AH Plus = most popular sealer (epoxy resin).
Tetracycline = most common intrinsic. In-office = 35% H2O2. Home = 10% carbamide peroxide. Walking bleach = non-vital teeth (sodium perborate).
