By performing a comprehensive medical and dental history, using precise terms and concepts, and utilizing the Revised Schema of Pathodynamic Mechanisms, the dentist may successfully identify and treat the etiology of root surface lesions. Preventive measures may be instituted if the causative factors are detected and their modifying factors are considered.

The prevalence of carious cervical lesions among the five archaeological populations studied ranged from 0 to 65%. Non-carious cervical lesions were not prevalent among these populations, being found predominantly in Mexicans (26%). CLINICAL SIGNIFICANCE Historically, carious and non-carious cervical lesions can be found in individuals with no access to modern oral hygiene tools. The findings of this study are not conclusive, however, as the associations described are not causal. (J Esthet Restor Dent 21:324-335, 2009).

This manuscript presents hypothetical and literary information that the combined effects of stress concentration and biocorrosion contribute to the formation as well as progression of cervical and root caries.

This chapter introduces the Air Indexing method for detecting and quantifying cervical dentin hypersensitivity as a companion to the T-Scan Occlusal Analysis System, which evaluates occlusal force and timing values of contacting teeth. The chapter discusses detection, diagnosis, and treatment of clinical signs and/or symptoms of Cervical Dentin Hypersensitivity (CDH). A 17-year-long retrospective study conducted between 1979 and 1996 is presented that illustrates the correlation between Cervical Dentin Hypersensitivity and its resolution following occlusal adjustment. Resulting stress from occlusal contact force is etiologic for non-carious cervical lesion formation and root degradation. This chapter details how biocorrosion and lost protective glycoproteins hasten the effects of applied force, creating CDH symptoms and cervical abfractions. Lastly, the Air Indexing method of CDH diagnosis is melded with T-Scan occlusal analysis to diagnose and treat CDH symptoms. Together, these two methods yield more CDH/occlusal insight than either method can alone.
