W e previously reported the lack of effect periodontally‐treated teeth prognosed “hopeless” and retained for 3.4±1.5 years have on the proximal periodontium of adjacent teeth. We now report our findings for the same group of subjects following 8.4±0.7 years of “hopeless” tooth retention. Of the 17 “hopeless” and adjacent teeth originally measured in 17 subjects, 14 of the subjects were still available for re‐evaluation. Measures used to assess the periodontium of proximal surfaces of adjacent teeth included pocket depths (PD), radiographic alveolar bone level (R‐BL), and periodontal ligament space width (W‐PL). Treatment for the subjects consisted of surgical therapy (N = 15) and scaling and root planing (N = 2). Of the 14 subjects re‐examined, 2 were eliminated due to loss of adjacent tooth reference points and 2 due to extraction of the “hopeless” tooth (N = 10). Differences in measurements (i.e., nonadjacent to “hopeless” tooth value minus adjacent to “hopeless” tooth value) were analyzed using a repeated measures ANOVA. There were no significant differences for PD ( P = 0.20), R‐BL ( P = 0.29), or W‐PL ( P = 0.16). These data confirm our original findings that retained periodontally “hopeless” teeth do not significantly affect the proximal periodontium of adjacent teeth following therapy.
