I have a strange problem hier, I'm trying to use this two libraries, but every time I call the function dht.readTemperature() and dht.readHumidity() looks like the Arduino restart the communication with the I2C, I am using an Arduino UNO.

Please define what that sentence mean. Most DHT implementations block interrupts while talking to the sensor. If you have that Arduino listening on I2C this may seriously disturb that communication. If you use I2C as a master only, it shouldn't be related.
