Results of Limited Initial Periodontal Therapy in Smokers and NonâSmokers
Eightyâseven adult patients (54 nonâsmokers and 33 smokers) with moderate to advanced periodontitis were treated with 1âhour fullâmouth subgingival scaling and root planing, with no maintenance recalls, during this 9âmonth study. Clinical parameters assessed at target sites included probing depth, clinical attachment level, bleeding on probing, gingival index, and plaque index. Data were collected at baseline, and 3, 6, and 9 months. Baseline probing depth for nonâsmokers was 5.46 ±.46 mm and for smokers 5.70 ± 0.66 mm. Data analysis (t test) revealed that both nonâsmokers and smokers had a statistically significant decrease (P \u3c 0.05) in probing depth at 3 months which was maintained throughout the study. At 9 months nonâsmokers maintained a mean decrease in probing depth of 0.60 mm and smokers a mean decrease of 0.65 mm. Both smokers and nonâsmokers displayed a significant gain (P \u3c 0.05) in clinical attachment level after initial therapy when compared to baseline readings. At 9 months the mean gain in clinical attachment level for nonâsmokers was 0.47 mm and 0.59 mm for smokers. Plaque index scores remained consistent for smokers and nonâsmokers for the duration of the study. The gingival index at baseline was significantly (P \u3c 0.05) lower in smokers (1.32 ± 0.45) than nonâsmokers (1.45 ± 0.40). By 9 months only the gingival index of nonâsmokers decreased significantly compared to baseline (1.26 ± 0.37). Bleeding on probing was a prerequisite for target sites at baseline. At 9 months both smokers (0.67 ± 0.39) and nonâsmokers (0.78 ± 0.30) had a significant decrease in bleeding on probing compared to baseline. At 9 months there were no significant differences between smokers and nonâsmokers comparing probing depth, clinical attachment level, plaque index, bleeding on probing, and gingival index. The data have shown that smokers and nonâsmokers responded similarly after 9 months to the limited amount of initial therapy provided
