Try:
$date = date_parse_from_format("Y.m.d", $row['DMT_DATE_DOCUMENT']);
$time = mktime($date['hour'], $date['minute'], $date['second'], $date['month'], $date['day'], $date['year']);
echo "<p><h6>".date('d/m/Y', $time)."</h6></p>";
(Using date_parse_from_format()instead strtotime())
Or simply:
$date = date_parse_from_format("Y.m.d", $row['DMT_DATE_DOCUMENT']);
echo "<p><h6>{$date['day']}/{$date['month']}/{$date['year']}</h6></p>";
