Tooth loss during maintenance following periodontal treatment in a periodontal practice in Norway

Abstract

Compliance with maintenance following periodontal treatment was associated with very low levels of tooth loss in a referral practice in rural Norway. Male gender, older age (>60 years) and smoking were predictors of tooth loss due to progressive periodontitis.

Tooth loss in individuals under periodontal maintenance therapy: prospective study

“…The final adjusted model revealed that the odds of men to present TL was three times higher than women (OR = 3.16, 95% CI 1.28-7.78). This data is similar to that reported by Fardal et al (2004). 8 Individuals with 10% of sites with PD between 4 and 6 mm presented 5 times more chances for TL (OR = 5.13, 95% CI 2.04-12.9).…”

“…4,6,8,[13][14][15][16][17] In a similar way to other prospective studies of TL in periodontal susceptible individuals, the present study aimed to describe the TL for periodontal disease and to analyze possible predictors of risk to the occurrence of this event.…”

“…[3][4][5][6] The vast majority of studies reported TL only during the maintenance period. 3,5,[7][8][9][10][11] However, recent studies recommended the description of TL prevalence during the active therapy and its incidence during PMT as a mean of assessing the overall effectiveness of periodontal therapies. 12,13 Moreover, most of the studies on TL in programs of PMT have retrospective designs, 3,4,[6][7][8]14 and as a consequence, data may reflect the traditional bias related to the design methodology.…”

A comprehensive approach to assigning periodontal prognosis

“…The accuracy of the TLPD prediction has been identified with the actual percentage of TLPD of teeth being assigned a certain prognostic category (Becker et al., 1984; Fardal et al., 2004; McFall, 1982; McGuire & Nunn, 1996). This percentage also represents the probability of TLPD.…”

“…A baseline sample of 500 patients was required (Martinez‐Canut, 2015) for a final sample of 22 LTO index 4 and 5. Interestingly, these 22 patients would represent 4.4% of our baseline sample of 500 patients, which is consistent with the actual percentage of patients experiencing higher TLPD rates reported in the literature, with the use of genuine TLPD samples instead of overall tooth loss samples (Chambrone & Chambrone, 2006; Checchi et al., 2002; Fardal et al., 2004; Lü et al., 2013; Muzzi et al., 2006). …”
