Deciduous don't have any molars. The I stands for incisor teeth. _________ is not high in fiber and does not encourage the grinding motions of the jaw that benefit tooth attrition in rabbits. There is a small pair of incisors called "peg teeth" that some rabbit herds may be missing as a dominant trait. The laterolateral view often yields the most valuable information regarding dental disease.1,7 The incisor teeth, cheek teeth, and supporting structures are easily evaluated for malocclusions.1,7 The appearance of the bone surrounding the teeth may also be assessed.1,6 The dorsoventral view is particularly helpful for evaluating the palatal and buccal margins of the cheek teeth and the zygomatic bone.1,7 Oblique projections of the skull are useful for separating individual cheek teeth of the mandible and maxilla, which are directly superimposed in laterolateral views.1 In 2009, Boehmer and Crossley introduced the use of anatomic reference lines when evaluating dental radiographs (BOX 2).1,7. More hay please...Prolonged chewing of tough, abrasive foods such as hay causes rapid tooth wear in rabbits and herbivorous rodents. Assessing pain in small mammals can be a difficult task, but it is not impossible. Their deciduous teeth are smaller in size and they erupt while the kit is still in the mother’s womb and they are replaced by permanent adult teeth. Assessing pain in small mammals can be a difficult task, but it is not impossible. The formula for permanent rabbit teeth is: 2 (I2/1 C0/0 P3/2 M2-3/3). 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). Their irregular occlusal surface gives them a rough surface over which fibrous and course food is ground using side-to-side chewing movement (to crush and shear food). 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. B. Spatulas. 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. Radiography is an essential diagnostic tool that should be performed for all patients with suspected dental disease.1 The bulk of the teeth and the supporting structures is below the gumline, hidden from view during gross oral examination. However, the endoscope permits substantial magnification, making small lesions easily detectable. Dorsoventral view, normal anatomy Vet Times November 1, 2011. vettimes.co.uk/article/recognising-and-managing-pain-in-small-mammals-and-exotics/. Manicinelli E. Recognising and managing pain in small mammals and exotics. Dental attrition of rabbit cheek teeth. This is due to anisognathism (mandible is narrower than the maxilla). Guinea pigs and rodents may display piloerection. All have a diastema between the incisors and cheek teeth. Dental Anatomy. Growing rabbits are especially susceptible to congenital malocclusions and metabolic bone disease if fed inappropriate, low-calcium food items early in life.5. Common dentistry equipment. Rabbits are a prey species, so they tend to hide clinical signs of illness until they are remarkably debilitated.2 Clinical signs of dental disease are directly related to the severity of the disease.2 If the dental disease is mild, the rabbit may not show any signs. Otherwise, their teeth will be overgrown if they do not have fibrous diets. Overgrooming, chewing at the location of pain, and self-mutilation are observed in small mammals, most commonly in rodents and sugar gliders. To compensate for the wearing down, all their permanent teeth are termed as eval(ez_write_tag([[300,250],'petsmentor_com-medrectangle-4','ezslot_2',110,'0','0']));elodont, i.e., they are ever-growing with open roots, i.e., they have open apices that do not form true roots (they are aradicular). Consequently, dental problems, if not treated, often lead to more generalized illness. Because the formula is for one side of the mouth the total number of teeth is the total in the formula x 2. 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. 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 other hand to pull the upper lip up and aside. iasp-pain.org/Taxonomy#Pain. Congenital causes are conditions present at birth. As prey species, small mammals mask signs of illness and injury, especially when in an unfamiliar environment. Bruxism, a loud tooth grinding, is a common clinical sign of pain 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). Powered by WordPress. FIGURE 5. 22. Rabbits have 2 on top and one on the bottom jaw. Place the patient in lateral position. She has fostered birds for the Des Moines Animal Rescue League since 2014. An increase in the frequency and depth of respirations or rapid, shallow breathing is also a sign of distress. However, this is not the case for baby rabbits. This answers the question, how teeth do bunnies have. The animal may be less active or even completely immobile. The dental formula of rabbits and hares is: I2/1; C0/0; P3/2; M3/3. These signs may include anorexia, lethargy, lameness, reduced grooming, abnormal vocalizations, aggression when usually docile, or any deviation from normal behavior.3 Many small mammals in pain hide under bedding or substrate. The most widely accepted dental formula for rabbits is 2× (I 2/1; C 0/0; P 3/2; M 3/3) = 28 [5 21–23]. • List the equipment needed for dental care of rodents, lagomorphs, and ferrets. The goals of treatment are to return teeth to their normal anatomy and to control inflammation and infection, thereby returning the teeth to normal function. On the other hand, domestic ones which to do not graze have grassy hays forming the bulk of their diet with some amounts of alfalfa-based hays, a few treats of non-leafy vegetables and fruits given to them. Appropriate multimodal analgesia techniques can and should be used in small mammals. Vet Clin Exotic Anim Pract 2007;(10):293-315. doi:10.1016/j.cvex.2006.12.002 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. 1 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. Once they have sensed their food, they use their prehensile lips to grasp the food before incisors cuts or bites it and moves it to premolars and molars using their tongue for grinding, chewing or mastication. The roots of anatomically normal maxillary cheek teeth will not extend past this line. Cheek teeth should not extend outside of these reference lines. Causes of dental disease are categorized as congenital or acquired. The part embedded into the jaw is often referred to as a reserve crown. 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]. Other animals, frequently rodents, spend more time than normal curled up and may have bulging eyes. As we have mentioned, they are elodont (grow continuously) and are aradicular (open-rooted). Sarah has written numerous articles and lectured extensively on exotic animal topics. The diastema is typical in not only lagomorphs but also in rodents. The Veterinary Technician’s Oath. Yes. However, the cheek ones (premolars and molars) grow at a slower rate with the mandibular ones growing at about 3-4 mm a month while the maxillary erupts much slower [1] than mandibular ones.eval(ez_write_tag([[336,280],'petsmentor_com-box-4','ezslot_16',129,'0','0'])); One research[2] has placed the growth rate at 1.9mm per week and 2.2mm per week for upper and lower incisors respectively while premolars at 2.14 mm per week with a plus or minus margin of 0.28 mm per week. Pull the front legs caudally and extend the head. All teeth are hypsodont (constantly growing) and grow about 2 mm weekly. Pull the front legs caudally. FIGURE 6. FIGURE 2. These pets have a total of six unpigmented incisors. Copyright © 2021 Today's Veterinary Nurse. What is the difference between the deciduous and adult dental formula of rabbits? 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. Various species and individuals have different pain responses and pain tolerance.4 Rats have a harderian gland that secretes red, porphyrin tears when they are ill or stressed, giving the appearance of bleeding eyes. 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]. Teeth are very important to an animal as they are used for eating, grooming and defense. Accessed October 2016. Place the patient in lateral recumbency. 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. • List the dental formulas of the hamster, rat, gerbil, guinea pig, ferret, and adult rabbit. Hence the teeth can be expressed by using the initials - I, C, Pm and P4. Get the latest business resources on the market delivered to your inbox. Various species and individuals have different pain responses and pain tolerance.4 Rats have a harderian gland that secretes red, porphyrin tears when they are ill or stressed, giving the appearance of bleeding eyes. Craniocaudal view of rabbit skull. E. Dental handpiece and cheek guard. Repeat with the patient in lateral position on the opposite side. Guinea pigs, which normally give high-pitched squeals when handled, also tend to be quiet during handling while painful. Harcourt-Brown F. The progressive syndrome of acquired dental disease in rabbits. Lennox A. Healthy incisors will be white and cylindrical, with a horizontal, chisel-shaped edge. The success of performing an oral examination on an unsedated rabbit varies depending on the stress level and cooperation of the rabbit. Lagomorphs have special adaptations to help obtain nutrients from a diet comprising large quantities of grasses. Rotate the patient’s head 40˚ away from the table. Place the patient in sternal recumbency. Place the patient in sternal recumbency. Since the patient will most likely be masking any signs of illness or discomfort, information obtained from the owner about how the animal has been acting in its normal environment will be helpful. However, the last deciduous premolars may take up to 35 days before they are all shed (about a month). Pull the front legs caudally. The dental formula is 2 x (I 2/1, C 0/0, P 3/2, M 3/3) = 28. 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 the maxillary cheek teeth are in close proximity to the periorbital space. RADIOGRAPHIC VIEW Boehmer E, Crossley D. Objective interpretation of dental disease in rabbits, guinea pigs and chinchillas. A thorough understanding of normal oral anatomy and physiology is necessary for prevention and treatment of dental disease in rabbits. 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). Web Design by PHOS Creative, BAS, RVT, VTS (Exotic Companion Animals), ISU Lloyd Veterinary Medical Center, Ames, IA, Canine Uveitis and the Veterinary Technician, Luxating Patellas: Pathology and Treatment Options. Accessed October 2016. There is no one objective way to tell if a small mammal is feeling pain, as individual animals display different clinical signs. A yellow line (C) highlights the mandibular cortical bone. The quiz is still a good way to test your knowledge! Recognizing and assessing pain in small mammals can be challenging. Mammalian heterodont dentition is expressed by a ‘dental formula’. The length of the first upper incisor is generally less than 7.5 mm (0.30 in). ... Eastern Cottontail Rabbit (Sylviagus floridanus) I 2/1 C 0/0 P 3/2 M 3/3=28 Swamp Rabbit (Sylvilagus aquaticus) Lateral view, normal anatomy Diagnosis and treatment of dental disease in pet rabbits. They consist of the premolars and molars. The dental formula is 2/1, 0/0, 3/2, 2-3/3 = 26-28. For instance, the incisors can grow at a rate of about 2mm to 2.4mm per week. Appropriate multimodal analgesia techniques can and should be used in small mammals. How many teeth do adult rabbits have? 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. FIGURE 4. Two yellow lines (C) highlight the medial cortex of the mandible, which should appear straight, smooth, and symmetric. Lichtenberger M, Ko J. Anesthesia and analgesia for small mammals and birds. The lack of canine teeth creates an elongated diastema between the incisors and premolars. The roots of anatomically normal mandibular cheek teeth will not extend past this line. We have included the below rabbit teeth diagram (images and pictures) to help you see how the incisors, premolars, and molars are placed on these animals’ upper and lower jaws. The I stands for incisor teeth. The dental formula for different species are as follows where I = incisors, C = canines, P = premolars and M = molars : Man (adult) I - 2/2 C - 1/1 P - 2/2 M - 3/3 = 16 x 2 = 32 . They have incisors, premolars and molars, and lack canines. Masses or swellings palpated along the ventral mandible could be an indication of. Use foam pads, rolled hand towels, or tape to assist with positioning the rabbit’s skull perfectly horizontal to the table. POSITIONING GUIDELINES Use sandbags to apply gentle pressure to the back of the patient’s neck to ensure the head is not tilted ventrally. Ferrets are reluctant to curl up while resting and commonly squint their eyes. To help handle these kinds of foods, their teeth are functionally and anatomically adapted. The dental formula of the rabbit is: 2 x ( I 2 / 1 C 0 / 0 P 3 / 2 M 3 / 3). Observation of the patient during the interview or in a quiet room before handling may reveal signs of pain or discomfort. Pull front limbs caudally and extend the head. The formula for permanent rabbit teeth is: 2 (I2/1 C0/0 P3/2 M2-3/3). The roots of anatomically normal maxillary cheek teeth will not extend past this line. This is indicated, for example, as follows: Rangifer (32/34) (which means that they will have either 32 or 34 teeth in total), or Dasypus (28-32) which means that they will have between 28 and 32 teeth in total. Ferrets are reluctant to curl up while resting and commonly squint their eyes. She currently works at ISU Lloyd Veterinary Medical Center in Ames, Iowa. Therefore a baby rabbit has a total of 16 deciduous teeth with the dental formula is 2 (2/1  0/0 3/2). The occlusal surface of the cheek teeth will appear to match this line in healthy rabbits. 2001. 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. Rabbits have six unpigmented incisor teeth. The animal may be less active or even completely immobile. She is a member of the National Association of Veterinary Technicians in America and International Association of Animal Behavior Consultants. Pollock C. Pain management in small mammals. Therefore, an adult’s rabbit dental formula is 2(2/1  0/0  3/2 3/3) = 28. A second black line (B) runs parallel to the first, extending from the rostral end of the hard palate to one-third of the height of the tympanic bulla. History and husbandry information about the patient should be obtained from the owner using open-ended questioning techniques upon arrival at the veterinary clinic. A. Molar cutters. Although it cannot be prevented in all pet rabbits, feeding a high-fiber diet and providing objects to encourage chewing are positive preventive practices. What is the deciduous dental formula for rabbits? Accessed October 2016. They also segregate themselves from their cage mates, positioning themselves on opposite ends of their enclosure. 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. These signs may include anorexia, lethargy, lameness, reduced grooming, abnormal vocalizations, aggression when usually docile, or any deviation from normal behavior.3 Many small mammals in pain hide under bedding or substrate. Dentition pertains to the development of teeth and their arrangement in the mouth.In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. A black line (A) extends from the tip of the nasal bone to the occipital protuberance. Can Rabbits Eat Nuts Including Monkey Nuts? The roots of anatomically normal mandibular cheek teeth will not extend past this line. Every rabbit that presents to the veterinary hospital should undergo a physical examination that includes an oral examination. We will answer that shortly. Accessed October 2016. Cheek teeth should not extend outside of these reference lines. The dental formula for rabbits is 2 x (12/1, C 0/0, P 3/2, M 3/3) = 28. The number and arrangement of teeth in each half of the upper and lower jaws is constant and identical. A yellow line (C) highlights the mandibular cortical bone. Manicinelli E. Recognising and managing pain in small mammals and exotics. The deciduous teeth have little clinical significance. References Before we state their dental formula, we need to elaborate. VeterinaryPartner.com. The fiber in bunnies diet is also important in ensuring gut motility and a healthy gut while eliminating the chances of GI stasis.eval(ez_write_tag([[580,400],'petsmentor_com-medrectangle-3','ezslot_11',126,'0','0'])); Since they have a small blind spot angle right in front of their mouth area, due to their eye location, they use their sensitive whiskers (vibrissae) on their lips to find food. okvta.org/veterinary-technicians-oath.html. Understanding the rabbit dental formula, anatomy, facts, and so on is essential in dealing with various rabbit teeth problems including disease or overgrowth as well as how to care for and ensure that these pets have healthy teeth. They also have a long crown (hypsodont). Therefore, you need to ensure you include enough of the fibrous foods to your bunny’s diet. Repeat with the patient in lateral position on the opposite side. Observation of the patient during the interview or in a quiet room before handling may reveal signs of pain or discomfort. The term _________ means the teeth have open apices, never forming true tooth roots. They also segregate themselves from their cage mates, positioning themselves on opposite ends of their enclosure. BOX 2 Boehmer and Crossley Radiographic Anatomic Reference Lines1,7 Dorsoventral Guinea pigs and rodents may display piloerection. Her interests include avian anatomy, physiology, behavior and enrichment; wildlife rehabilitation; and anesthesia. When rabbits are fed an inappropriate diet, their teeth can overgrow, resulting in malocclusions and other abnormalities. Rodents have enlarged chewing muscles that allow their jaw to work in a vertical, forward and backward motion. Accessed October 2016. Some authors use the term aradicular hypsodont, indicating that the teeth have Article #2 ABSTRACT: CE Pollock C. Pain management in small mammals. Occasionally, an abscess is detectable only on radiography or CT.1 Treating a rabbit with an abscess can be difficult because the pus has a remarkably thick-to-solid consistency.1 Primary treatment of an abscess is to remove the cause, which is 1 or more infected teeth.1 Further treatment of the abscess varies by veterinarian preference but may include repeated lancing and flushing of the abscess, systemic antibiotics, complete surgical excision of the abscess, and antibiotic bead impregnation.1,3 Analgesia and nutritional support may be indicated in patients that have an abscess.1, Proper nutrition and husbandry are essential for the prevention of dental disease. Place the patient in dorsal recumbency. There is a small pair of incisors called "peg teeth" directly caudal to the primary maxillary incisors.

Rabbits that eat a diet high in calcium are at risk for. Two yellow lines (C) highlight the medial cortex of the mandible, which should appear straight, smooth, and symmetric. Oklahoma Veterinary Technician Association. If positioned correctly, both of the patient’s eyes will be horizontal to the table. Also, the auxiliary incisors prevent the lower incisors from injuring the palate. Annual physical examinations of pet rabbits assist in early detection of dental disease. 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. Congenital causes include prognathism, brachygnathism, and other jaw malformations.2 For example, a malformation of the incisors may cause improper wear of the cheek teeth, eventually leading to the development of sharp points and overgrowth of the cheek teeth. A cursory examination of the cheek teeth may be performed without sedation by using a bivalve nasal speculum or an otoscope cone. Rabbit dental formula for those really interested; 2 (I2/1 C0/0 PM3/2 M3/3) = 28 The 2 in the front of the formula indicates the left and right side of the mouth. History and husbandry information about the patient should be obtained from the owner using open-ended questioning techniques upon arrival at the veterinary clinic. Treatment of dental disease consists of returning teeth to their normal length, restoring normal occlusion, extracting diseased teeth, and treating associated abscesses. Accessed October 2016. Acquired dental disease is not inherited but rather the result of external factors.2. There is no one objective way to tell if a small mammal is feeling pain, as individual animals display different clinical signs. This study is linked to diets given. It may display a hunched posture, arch its back, or press its abdomen to the floor.3 If you did not know or you assumed that they have 32 teeth like human beings, the truth is that an adult rabbit has 28 teeth forming a natural curve. If applicable, position the affected side nearest to the cassette. BOX 1 Positioning Guidelines for Dental Radiography in Rabbits7,8 LafeberVet; April 23, 2011. lafeber.com/vet/pain-management-in-small-mammals. LafeberVet; April 23, 2011. lafeber.com/vet/pain-management-in-small-mammals. These types of teeth serve various functions such as cutting up, crushing, tearing and shredding the food. While checking and caring for your rabbit’s teeth, a dental chart may be handy. Check Ans It may display a hunched posture, arch its back, or press its abdomen to the floor.3. Four on their top jaw (maxilla ) and two on their mandible (lower jaw). In lagomorphs, the location of the two smaller rudimentary maxillary incisors (peg teeth) directly caudal to the two large grooved incisors is a double-row dentition. Two yellow lines (C) highlight the medial cortex of the mandible, which should appear straight, smooth, and symmetric. Use tape or foam wedges on either side of the head to prevent rotation if necessary. They have 6 incisor teeth and 22 cheek teeth (molars and premolars). The rabbits weigh between 0.7 kg and 1.2 kg and are between 35 cm and 39 cm in body length. 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. They continually grow. Laterolateral There is a small pair of incisors called "peg teeth" that some rabbit herds may be missing as a dominant trait. The lateral and dorsal surfaces of the cheek teeth are difficult or impossible to evaluate in this fashion, and small dental lesions are easily missed.1, An endoscope may also be used to view the cheek teeth. 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. _________ skull radiographic views often yield the most valuable information regarding dental disease in rabbits. In some patients, it may be useful to open the mouth slightly with a small cotton prop to separate the occlusal surfaces of the maxillary and mandible teeth. 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. In some patients, it may be useful to open the mouth slightly with a small cotton prop to separate the occlusal surfaces of the maxillary and mandible teeth. Pain Assessment in Small Mammals Sarah Kolb, RVT, VTS (Clinical Practice–Exotic Companion Animals) Vertically position ventral margins of the mandible and both eyes. Pull the front legs caudally and extend the head. To compensate for this, these species have permanent teeth that grow and erupt continuously, never producing anatomical roots. Overgrooming, chewing at the location of pain, and self-mutilation are observed in small mammals, most commonly in rodents and sugar gliders. 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. Yes. Vertically position ventral margins of the mandible and both eyes. Note the chisel-like appearance of the incisors and the occlusion of the mandibular incisors to the peg teeth. However, once one tooth is affected, over time, the dental disease will affect all the other teeth. Another advantage of the endoscope is the ability to take pictures, allowing owners and other members of the veterinary team to see the oral cavity.1, Blood analysis is indicated if systemic disease is suspected or anesthesia is required for a dental procedure.5.
