Background

Both periodontitis and dental caries have a multifactorial pathogenesis caused by complex interactions between environmental, etiologic, and host factors combined with genetic predisposition. Bacterial colonization of tooth surfaces plays an essential role in the development of periodontal diseases, and acid production by bacteria in the oral biofilm is a direct causative factor for the demineralization of tooth surfaces in caries development. With prolonged acidic conditions, the amount of

Methods

The 136 patients (mean age 54.6 years, range 26 to 77 years) had undergone periodontal treatment, then were re-examined after 10 years. Thirty-six patients had AgP, 37 moderate ChP, and 69 severe ChP. For each patient, dental status and periodontal health were determined. Patients’ charts were assessed for diagnosis, compliance with supportive periodontal treatment (SPT), and patient’s DMF-T/S at baseline compared to 10 years later. The change in DMF-T/S was calculated, and factors that might

Results

Seventy-two patients (27.2%) were compliant with therapy, 32 (23.5%) smoked, and 47 (34.6%) smoked formerly. Gingival bleeding index (GBI) ranged from 0% to 43%, with a mean of 7% during follow-up. Plaque control record (PCR) ranged from 2% to 64%, with a mean of 25%. The two groups did not differ in mean PCR.

Baseline mean DMF-T was 16.27; at reevaluation it was 18.34. DMF-T showed a mean difference of 2.07 over the period of follow-up. Lower DMF-T was found in patients with AgP at baseline,

Discussion

Patients with AgP and ChP diagnoses have statistically significant differences in DMF-T and DMF-S at baseline, with AgP patients having less DMF-T and DMF-S than ChP patients. Over the course of 10 years, DMF-T and DMF-S both increased similarly in both groups, with no statistically significant differences. Regularity of maintenance and compliance with treatment contribute significantly to improved general dental status.

Clinical Significance

Intuitively it seems plausible that a decline in
