RIGO, Lilian et al. Periodontal conditions and factors associated with the probing depth in patients from a faculty in southern Brazil. Int. j interdiscip. dent. [online]. 2020, vol.13, n.3, pp.135-139. ISSN 2452-5596.


To evaluate periodontal clinical signs and investigate the probing depth levels (PD) and associated factors in patients attending the Dental Clinics of the Faculty IMED, located in a municipality in southern Brazil.

Material and Methods:

The data were collected of 193 records of patients who demand dental care in the Dental Clinics for periodontal treatment, in the period 2017- 2018: sociodemographic data, oral hygiene habits, tobacco use and chronic diseases. The clinical data were: gingival bleeding index (GBI), visible plaque index (VPI) and PD. The statistical analyzed the relationship between probing depth and exposure variables, using a linear regression linear model (p-value<0.05).


The majority of the patients attended were female (63.2%) and 40.8 years old on average (± 14.58). The descriptive results of VPI, GBI e PD were: 39.11 ± 32.28%, 21.81 ± 22.43%, and 2.91 ± 1.09mm, respectively. After adjustments in the multiple regression model, it was observed that diabetes and quantity of cigarettes smoked had an influence on PD.


The results obtained in this research allowed to verify a high index of VPI and GBI in the patients. The mean PD of the individuals was low, however, it was possible to verify that having diabetes and smoking a large amount of cigarettes daily were predictive factors of higher levels of PD.
