Tooth shortening and endodontic therapy

27 Tooth shortening and endodontic therapy




INITIAL PRESENTATION


Inability to close mouth.



PATIENT DETAILS


An 11-month-old, male, bearded collie.



CASE HISTORY


The owner was concerned that the dog didn’t seem to be able to close his mouth completely and drooled continuously. Also, he would not play with toys and would only eat soft food.


The dog had been involved in a slow speed accident with a car when 6 months old (the owner had accidentally backed into him). He had seemed unhurt at the time. The problem with jaw closure was noted roughly a month after the accident and had been getting progressively worse.


The dog was seen by its own veterinarian, who referred the case to us for evaluation and treatment.



ORAL EXAMINATION – CONSCIOUS


This was a nice-tempered dog that allowed thorough oral examination and occlusal evaluation (Figs 27.1 and 27.2).

Figure 27.1 Wry bite – rostral view in the conscious animal. Occlusion is best examined in the conscious animal. The dog does not allow closure of the mouth and drools continuously. There is obvious saliva staining of the fur. Note the midline deviation of the incisors. Tooth 404 is flared out, and there is space in the diastema between 103 and 104 for this tooth to fit in normal occlusion if the jaws were able to close.

The following were noted:


1. Saliva-soaked and saliva-stained fur around jaws

2. Would not allow full closure of jaws

3. Generalized gingivitis

4. Complicated crown fracture (CCF) of 101

5. Occlusion:
• The upper jaw was longer on the left than on the right side

• The lower jaw was of normal length and width for the breed

• There was an obvious midline deviation of incisors

• Tooth 304 was upright in position and occluded with the palate, causing a 14-mm-deep ulcerated indentation

• Tooth 404 flared laterally and fitted into the diastema between 103 and 104.


ORAL EXAMINATION – UNDER GENERAL ANAESTHETIC


A thorough oral and dental examination, including investigating periodontal parameters, was performed. All findings were noted on the dental record sheet.


In summary, examination under general anaesthesia identified the following:


1. Generalized gingivitis

2. Complicated crown fracture (CCF) of 101

3. Occlusion:
• The upper jaw was longer on the left than on the right side, with obvious midline deviation

• The lower jaw was of normal length and width for the breed

• Tooth 304 was upright in position and occluded with the palate, causing a 14-mm-deep ulcerated indentation, which was filled with debris
