The aim was to compare the efficacy of plaque control and potential effects on gingival recession of the toothbrushes with angled and straight bristles. A total of 40 healthy dental students (25 females and 15 males; age range: 23-25 years) participated and two study groups were constituted. Participants were randomly distributed into two groups to use either angled or standard design manual tooth brushes with soft bristles. Oral hygiene indicators and soft tissue levels were monitored for 6 months. Plaque index, gingival index (GI), probing depth, clinical attachment level, and bleeding on probing were measured at six sites. Vertical recession (VR) and horizontal recession (HR) were also recorded. All measurements were repeated at 3 and 6 months. Plaque scores were reduced significantly at 6 months compared to baseline in both groups (P < 0.05 and P < 0.005 in criss …
