These are radiographs of a 4 yo male Springer Spaniel named Rufus.
107 and 207 each have a 3rd root. I am concerned that this root is resorbing. Grossly the tooth appears normal with 2-3 mm periodontal pockets along palatal aspect, around the extra root. I chose to monitor these teeth, but wanted to get a 2nd opinion. I tend to be conservative and monitor early root resorption as long as it is not near the crown. However, after going to the Dental Forum, I question if I should be more pro-active.
Also, 409 had enamel hypoplasia on both the lingual and buccal aspects of the crown. This was first noted when he was about 9-12 mo old. I performed a restoration at that time. The restorative has held up well along the lingual aspect but has come off on the buccal aspect. I have 2 questions about this tooth. 1.Would you advise at least re-applying a bonding agent annually to these areas of hypoplasia? I have seen mixed opinions/answers to this question. Once the area has been bonded, doesn't repartive dentin form to protect the area? 2. There is a small rough area (catches with probe) along the mesial aspect of the tooth (right at interdental space of 408-409). This is seen as a lucency on radiograph as well. I reflected the gingiva to visualize and can see a subtle defect (with 2.5 x magnifying loopes). Thoughts on what this is and if any action should be taken?
