Dent will be in charge of the Time Warner-owned magazine firm's biggest revenue-earning division.
Dent's promotion is the first significant appointment made by IPC's new chief executive, Evelyn Webster.
Webster ran the women's division, which houses titles including Look and Woman, before her promotion to the top job in December last year.
As part of the change, Charlie Meredith, current publishing director of What's on TV and TV Easy, will take on Dent's previous role, overseeing its TV brands such as TV Times and TV & Satellite Week.
Dent, who joined IPC in 1992, has been managing director of IPC TX since April 2007. She has held a variety of senior marketing and publishing roles and between 2003 to 2006 was publishing director of Country Life and Horse & Hound.
Meredith joined IPC TX soon after the launch of What's on TV in 1992. He was the publishing director behind the launch of TV Easy, the UK's first compact TV weekly, in 2005.
The appointments will be effective from 1 February, when Meredith will join the IPC board, which Dent already sits on.
Both of the new appointments will report directly to Webster.
IPC announced in December that Webster was to replace Sylvia Auton as chief executive with the appointment effective from 1 January. Auton is now chairman of IPC Media and executive vice president of Time Inc.
Webster's promotion follows the departure of IPC's managing director of advertising, Caroline McDevitt, in November. Webster now combines McDevitt's duties as well as her chief executive role.
Webster said the two internal appointments indicated the talent that IPC houses within its business, adding that Dent's experience across the weekly division will prove crucial.
