He researched many important topics to dentistry, including the best composition for dental amalgams and the cause of dental fluorosis. One of his many inventions was a foot-driven dental drill. Black was the first to use nitrous oxide for "extracting teeth without pain." He is also known for his principles of tooth preparations, in which he outlines the proper methods to prepare teeth for fillings. The phrase, "extension for prevention," is still famous in the dental community today and represents Black's idea that dentists should incorporate more grooves and pits than those currently exhibiting decay as a preventive measure against those grooves and pits developing tooth decay in the future.
Further, he organized 'Black's Classification of Caries Lesions' which is still in use today. Since that time, only one more category has been added to his classification system.
Black's Classification of Caries Lesions:
* Class I: Caries affecting pit and fissure, on occlusal, buccal, and lingual surfaces of posterior teeth, and Lingual of anterior teeth.
* Class II: Caries affecting proximal surfaces of molars and premolars.
* Class III: Caries affecting proximal surfaces of central incisors, lateral incisors, and cuspids.
* Class IV: Caries affecting proximal including incisal edges of anterior teeth.
* Class V: Caries affecting gingival 1/3 of facial or lingual surfaces of anterior or posterior teeth.
* Class VI: (never described by Black, added later by others) Caries affecting cusp tips of molars, premolars, and cuspids.
