General [[anaesthesia]] is required for radiography. Ideally, [[Oral Examination Under General Anaesthesia|clinical examination]] and [[Dental Recording|recording]] should precede the radiographic evaluation. It is also useful to clean the teeth before any radiographs are taken. Dental calculus, because it is radiodense, can obscure pathological lesions on a radiograph.

*Intra-oral techniques should produce radiographs without superimposition of the contralateral side which occurs if an extraoral technique is used.

*Use the correct size film allowing the best possible positioning.

*Use the correct size film allowing the best possible positioning.

*Position the film inside the mouth as close to and as near parallel to the structures to be radiographed without bending the film. This minimizes the risk of distortion.

*Position the film inside the [[Oral Cavity Overview - Anatomy & Physiology|mouth]] as close to and as near parallel to the structures to be radiographed without bending the film. This minimizes the risk of distortion.

*Use paper towel, foam or cotton-wool behind the film to wedge it and maintain its position.

*The xray beam is positioned perpendicular to the film and subject.

*The xray beam is positioned perpendicular to the film and subject.

*The animal is placed in lateral recumbency with the side to be radiographed uppermost. The intra-oral film is placed [[Dental Terminology|lingual]] to the [[Dental Formula - Dog#Premolars|premolar]] or [[Dental Formula - Dog#Molars|molar]] with the dimple facing towards the [[:Category:Teeth - Anatomy & Physiology|teeth]]. The film needs to gently be pushed ventrally to get the lower edge of the film as close to the ventral border of the [[Skull and Facial Muscles - Anatomy & Physiology#Mandicle (mandibula)|mandible]] as possible.
