Changes in , and oral health conditions following Prenatal Total Oral Rehabilitation among underserved pregnant women.

OBJECTIVES

To assess the oral health condition and oral microbial outcomes from receiving an innovative treatment regimen - Prenatal Total Oral Rehabilitation (PTOR).

METHODS

This prospective cohort study included 15 pregnant women in the PTOR group who had a baseline visit before PTOR and three follow-up visits (immediate after, 2 weeks and 2 months) after receiving PTOR. A historical control group of additional 15 pregnant women was matched from a separate study based on a propensity score. Along with demographic and medical background, oral health conditions and perinatal oral health literacy were assessed. Oral samples (saliva and plaque) were analyzed to identify and quantify and species by culturing-dependent and -independent methods.

RESULTS

Significant reductions of salivary were observed following PTOR, the effect remained until 2-month follow-up ( < 0.05). The carriage of salivary and plaque at the 2-month visit of the PTOR group was significantly lower than that of the control group ( < 0.05). Oral health conditions reflected by BOP and PI were significantly improved upon receiving PTOR ( < 0.05). Receiving PTOR significantly improved the perinatal oral health literacy score, and the knowledge retained until 2-month follow-up ( < 0.05).

CONCLUSIONS

PTOR is associated with an improvement in oral health conditions and perinatal oral health literacy, and a reduction in carriage, within a 2-month follow-up period. Future clinical trials are warranted to comprehensively assess the impact of PTOR on the maternal oral flora other than and , birth outcomes, and their offspring's oral health.
