The OHI-S index was calculated using the following formula:
OHI-S = sum of vestibular and lingual indexes/total of examined surfaces
OHI-S index scores were analyzed on day one (baseline), before the use of dentifrices for each specific group.
OHI-S index scores were initially submitted to the D'Agostino-Pearson normality test, and a normal distribution was detected.
The mean and standard deviation values of the OHI-S index scores in each evaluated group and time are illustrated in Figure 1 and are described as follows:
The statistical analysis demonstrated that the OHI-S index scores are affected by time (p < 0.
Even though the OHI-S index score means of G2 and G3 were lower than G1, the results at day 45 suggest that this amount of time using the tested toothpastes was not sufficient to promote a statistically significant difference in dental biofilm control.
The OHI-S showed a great association with oral hygiene habits.
The OHI-S index devised by Green and Vermillion (1964) was used to assess the degree of oral hygiene.
The present study also concluded that the CPI and OHI-S have a great association with the caloric intake value by Jain monks because, according to their caloric intake, all the Jain monks were considered to be malnourished.
