Subjects were chosen by consecutive sampling method. The subject’s teeth except Molar III were evaluated for probing depth, bleeding on probing, calculus, and the results were interpreted according to CPITN (WHO,1997). Evaluation were conducted at Dental and Oral Health Clinic at Sanglah Hospital and Gianyar Hospital. Results: The subjects characteristic was not different between the two groups, hence its influence could be avoided. Using Chi-Square test, we found that periodontal disease on pregnant women was associated with preterm birth, with prevalence ratio of 2.30 (CI 95% 1.69-3.13, p=0.011). Conclusion: Diseases on pregnant mother is associated with the incidence of preterm labor.
