Data collection tools were demographic checklist and oral health assessment checklist which were completed by interview and observation. Data were analyzed using SPSS software version 22 and independent t-test.

The patients in both intervention and control groups were homogeneous in terms of demographic and clinical characteristics.

The miswak group improved significantly; in other words, the effect of miswak on oral health was more than chlorhexidine mouthwash.
