Rabbits that eat a diet high in calcium are at risk for. However, during chewing (side to side movement), they do come in contact to help grind food by “the movement of the mandible caudally and shifting of the condyloid process into a step of the temporal joint surface.” [3]. Pull the front legs caudally. A cursory examination of the cheek teeth may be performed without sedation by using a bivalve nasal speculum or an otoscope cone. Her interests include avian anatomy, physiology, behavior and enrichment; wildlife rehabilitation; and anesthesia. Causes of dental disease are categorized as congenital or acquired.

(C) Four maxillary incisors, including the 2 smaller peg teeth situated directly behind the larger set of incisors, and 2 mandibular incisors. Use foam or rolled hand towels to support the neck of the patient and tilt the patient’s nose toward the table top, achieving a ventrodorsal position. Therefore, these animals must eat a lot of these grasses for survival. Diagnosis and treatment of dental disease in pet rabbits. These animals do not have canines. The crowns of the cheek teeth are relatively simple, with transverse basins separated by enamel ridges. Cheek teeth should not extend outside of these reference lines. However, the endoscope permits substantial magnification, making small lesions easily detectable. If applicable, position the affected side nearest to the cassette. VeterinaryPartner.com/Content.plx?P=A&A=472. The roots of the maxillary cheek teeth are in close proximity to the periorbital space. Another black line (B) extends from the lateral margin of the mandibular incisors to the lateral wall of the tympanic bulla on the opposite side. The palatal-lingual aspect of the maxillary cheek teeth wear more than the buccal aspects of these teeth. Dental Anatomy. Right and left 40˚ oblique Rabbit owners should be instructed to feed unlimited high-fiber foods.3,5 Grass, a good-quality timothy hay, and fibrous, green, leafy vegetables are favorable foods that are high in fiber and encourage the grinding motions of the jaw that benefit attrition of the teeth.7 Rabbits require a diet that provides enough calcium for sufficient mineralization of their continually growing teeth and surrounding bone structures, but not so much calcium that urinary tract disease is a risk.5 The ideal amount of dietary calcium for a rabbit is 0.5% to 1.0%.5, Barn-dried hay may not contain as much vitamin D as sun-dried hays.5 Alfalfa hay is very high in calcium.7 It is a good choice for rapidly growing young rabbits but should not be fed as a sole source of hay for adult rabbits.5 If possible, rabbits should be allowed to graze outside on a variety of grasses and weeds while basking in the sun, which helps prevent a vitamin D deficiency.5, Pellets are not a necessary part of a rabbit’s diet. Bunnies teeth i.e., they are diphyodont. Ferrets are reluctant to curl up while resting and commonly squint their eyes. Get the latest business resources on the market delivered to your inbox. The animal also has a rounded braincase, and a dental formula of 2/1, 0/0, 3/2, 3/3 with rather large molariform teeth. Every rabbit that presents to the veterinary hospital should undergo a physical examination that includes an oral examination. If positioned correctly, both of the patient’s eyes will be horizontal to the table. Masses or swellings palpated along the ventral mandible could be an indication of. A black line (A) extends from the tip of the nasal bone to the occipital protuberance. Rotate the patient’s head 40˚ away from the table. History and husbandry information about the patient should be obtained from the owner using open-ended questioning techniques upon arrival at the veterinary clinic. The occlusal surface of the cheek teeth will appear to match this line in healthy rabbits. When the jaw is at rest, the mandibular incisors should meet the peg teeth directly behind the maxillary incisors.1, The oral cavity of rabbits is small, making it impossible to examine the cheek teeth without instrumentation and sedation. Systemic disease that causes any change in a rabbit’s normal diet and eating patterns may lead to dental disease.1–4 A systemic disease characterized by altered calcium levels may result in changes in jawbones and altered tooth placement.3,5, Improper nutrition is the most common cause of dental disease in pet rabbits.3 Improper food items prevent normal tooth wear, eventually leading to dental disease.3,5. Another black line (B) extends from the lateral margin of the mandibular incisors to the lateral wall of the tympanic bulla on the opposite side. The roots of anatomically normal maxillary cheek teeth will not extend past this line. Other animals, frequently rodents, spend more time than normal curled up and may have bulging eyes. The length of the first upper incisor is generally less than 7.5 mm (0.30 in). Rabbit is herbivorous animal and depends on cellulose based food. The success of performing an oral examination on an unsedated rabbit varies depending on the stress level and cooperation of the rabbit. However, once one tooth is affected, over time, the dental disease will affect all the other teeth. The interview process also allows time for the animal to become accustomed to the veterinary clinic setting. Guinea pigs, which normally give high-pitched squeals when handled, also tend to be quiet during handling while painful. The dental formula of rabbit is 2 (I2/1 C0/0 PM3/2 M3/3). The diastema is typical in not only lagomorphs but also in rodents. Some rabbit herds may be missing these peg teeth, as a dominant trait Rabbit teeth are hypsodont, meaning they continue to grow throughout life - open roots Manicinelli E. Recognising and managing pain in small mammals and exotics. Recognizing and assessing pain in small mammals can be challenging. The animal may be less active or even completely immobile. As prey species, small mammals mask signs of illness and injury, especially when in an unfamiliar environment. Veterinary technicians play a critical role in educating rabbit owners about early clinical signs of dental disease, as well as diagnostic modalities and treatment options for a pet rabbit with suspected dental disease. As with an otoscope cone or bivalve nasal speculum, the endoscope does not allow a thorough evaluation of the cheek teeth in an awake patient. Dental Anatomy of Rodents Rodents are a very diverse order that include the large capybara, squirrels, beaver, chinchillas as well as porcupines and of course rats and mice. Veterinary technicians play a vital role in educating rabbit owners about prevention and early detection, as well as assisting veterinarians with diagnosing and treating dental disease. G. Incisor luxator. The incisors are examined by pulling the lower lip down with the thumb and forefinger of one hand while using the thumb and forefinger of the other hand to pull the upper lip up and aside in similar fashion (FIGURE 5). If dental disease is suspected, a more thorough oral examination should be performed with the patient under anesthesia.1 Rabbits with advanced dental disease commonly present with anorexia, pain, gastrointestinal stasis, or other secondary illness. When the jaw is at rest, the cheek teeth do not touch. As we have mentioned, they are elodont (grow continuously) and are aradicular (open-rooted). Lateral view, normal anatomy Observation of the patient during the interview or in a quiet room before handling may reveal signs of pain or discomfort. The veterinary technician oath states, “I solemnly dedicate myself to aiding animals and society by providing excellent care and services for animals, by alleviating animal suffering, and promoting public health.”5 Veterinary technicians play an integral role in recognizing pain in patients and act as patient advocates to alleviate pain and suffering in all animals. They are ever growing because they have a germinal tissue found on the teeth’ apices whose role is to continuously form enamel which covers the root making part of the tooth beneath and above gumline similar (white). Other animals, frequently rodents, spend more time than normal curled up and may have bulging eyes. All humans have four types of teeth: incisors, canines, premolars, and molars. Therefore, you need to ensure you include enough of the fibrous foods to your bunny’s diet. The deciduous incisors will begin to shed just before or immediately after birth. Although the underlying cause of dental disease can be congenital or traumatic, husbandry is a major influence in the prevention, onset, and treatment of dental disease. The deciduous teeth have little clinical significance. In place for canines, they have a long gap or diastema. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Merskey H, Bogduk N, eds. The upper incisors are set in a way that there are a longer outer curved set of two incisors and right behind them, there are shorter peg-like incisors often referred as to ‘peg teeth’ or auxiliary incisors, typical to most lagomorphs.eval(ez_write_tag([[300,250],'petsmentor_com-banner-1','ezslot_17',132,'0','0'])); Although both the upper and lower incisors are chisel-like, the upper ones shorter than the lower ones. By inserting the speculum or cone through the diastema into the oral cavity, the occlusal surface of the cheek teeth may be briefly examined, although the viewing window is limited. The 2 in the front of the formula indicates the left and right side of the mouth. Cheek teeth should not extend outside of these reference lines. An increase in the frequency and depth of respirations or rapid, shallow breathing is also a sign of distress. Use tape or foam wedges on either side of the head to prevent rotation if necessary. This means that all of the species listed have that particular dental formula. Rabbits are unique in that they have 4 maxillary incisors (101, 102, 201, and 202) and 2 mandibular incisors (301 and 401) (FIGURE 1).1–5 Two of the maxillary incisors (102 and 202) are significantly smaller and are called the peg teeth.1–5 The peg teeth are located directly behind the larger set of 2 incisors (101 and 201).1–5 The maxillary incisors are typically shorter than the mandibular incisors and have a longitudinal groove on the labial surface that runs the length of each incisor tooth.1–5, When the jaw is at rest, the mandibular incisors are situated behind the first larger set of maxillary incisors in occlusion with the peg teeth, and the cheek teeth do not touch (FIGURE 2).1–5 Lack of contact between the molars is due to anisognathism, meaning the mandible is narrower than the maxilla.1,5. The animal may be less active or even completely immobile. Oklahoma Veterinary Technician Association. Pull front limbs caudally and extend the head. What is the deciduous dental formula for rabbits? Also, the auxiliary incisors prevent the lower incisors from injuring the palate. Sarah earned a Bachelor of Applied Science in Veterinary Nursing from St. Petersburg College and the Veterinary Technician Specialty (Exotic Companion Animals). More hay please...Prolonged chewing of tough, abrasive foods such as hay causes rapid tooth wear in rabbits and herbivorous rodents. Guinea pigs and rodents may display piloerection. When rabbits are fed an inappropriate diet, their teeth can overgrow, resulting in malocclusions and other abnormalities. Computed tomography (CT) is becoming a widely accepted alternative to dental radiography in specialty and academic facilities.1,2 CT allows 3-dimensional reconstruction of the skull, viewing of finer detail than can be seen on radiographs, and isolation of areas or teeth of interest.1 CT is especially advantageous for evaluating intranasal structures, surrounding soft tissue structures, abscesses, and neoplasia.1. It may display a hunched posture, arch its back, or press its abdomen to the floor.3. LafeberVet; April 23, 2011. lafeber.com/vet/pain-management-in-small-mammals. Dental formula of rabbit is (A) (2/1) (0/0) (3/2) (3/3) (B) (2/1) (1/0) (3/2) (3/3) (C) (2/1) (0/0) (2/2) (3/3) (D) (1/1) (3/2) (0/0) (3/3). The formula for permanent rabbit teeth is: 2 (I2/1 C0/0 P3/2 M2-3/3). In these animals, the incisors and molars have different functions, i.e., there is the “cheeks fold in behind the incisors separating the front of the oral cavity from the more caudal section, thereby permitting separate function of the incisors and back teeth.”[1]. We will answer that shortly. FIGURE 4. If pellets are fed, they should be timothy hay based, not alfalfa based.5 Pellets require a less desirable chewing motion of the jaw, not the grinding motion required for fibrous grasses and hays.5 Mixed-cereal foods are also not recommended because it is impossible to prevent rabbits from selectively feeding.5, In addition to proper nutrition practices, owners can be educated about acquiring their pet rabbits from breeding stock without a history of dental disease in their lineage.
