Crowded and Rotated Teeth Crowded Teeth Are Common in Small Breed Dogs, While Crowded and Rotated Premolars Are Typically Seen in Brachycephalic Breeds
1 Crowded and rotated teeth Crowded teeth are common in small breed dogs, while crowded and rotated premolars are typically seen in brachycephalic breeds. To some this might suggest that the propensity for crowded, rotated teeth have a hereditary link. Studies show that the smaller the dog, the larger the teeth are in proportion to the mouth when compared to the teeth and mouths of larger dogs. Rotated and/or crowded conditions can occur in a single tooth, in multiple teeth, or in any combination. It is not uncommon to find crowded mandibular incisors in brachycephalic breeds. (Figure 1). Another common finding in many breeds, but especially in brachycephalics, is maxillary third premolars crowded with maxillary fourth premolars or the mandibular fourth premolars crowded with first molars. The maxillary third premolars and mandibular fourth premolars are usually also rotated in this condition .(Figure 2) Another common condition is incisors crowded together but also against the canine teeth Figure 1: Crowding of the mandibular incisors. Treatment included extracting the right and left mandibular second incisors. Figure 2: Crowded and rotated maxillary third premolars in a brachiocephalic dog 2 Rotation and crowding can cause pain from chronic tooth on tooth contact. This might be compared to the pain that humans experience from a caries that has been overfilled. It is a condition that generally does not result in clinical signs; however, it can be quite painful. The chronic trauma resulting from tooth on tooth contact can lead to tooth non vitality. Rotation and crowding can also result in tooth on soft tissue contact, which can be not only painful but can result in soft tissue defects. -
Veterinary Dentistry Extraction
Veterinary Dentistry Extraction Introduction The extraction of teeth in the dog and cat require specific skills. In this chapter the basic removal technique for a single rooted incisor tooth is developed for multi-rooted and canine teeth. Deciduous teeth a nd feline teeth, particularly those affected by odontoclastic resorptive lesions, also require special attention. Good technique requires careful planning. Consider if extraction is necessary, and if so, how is it best accomplished. Review the root morphology and surrounding structures using pre-operative radiographs. Make sure you have all the equipment you need, and plan pre and post-operative management. By the end of this chapter you should be able to: ü Know the indications for extracting a tooth ü Unders tand the differing root morphology of dog and cat teeth ü Be able to select an extraction technique and equipment for any individual tooth ü Know of potential complications and how to deal with them ü Be able to apply appropriate analgesic and other treatment. Indications for Extraction Mobile Teeth Mobile teeth are caused by advanced periodontal disease and bone loss. Crowding of Teeth Retained deciduous canine. Teeth should be considered for extraction when they are interfering with occlusion or crowding others (e.g. supernumerary teeth). Retained Deciduous Teeth Never have two teeth of the same type in the same place at the same time. This is the rule of dental succession. Teeth in the Line of a Fracture Consider extracting any teeth in the line of a fracture of the mandible or maxilla. Teeth Destroyed by Disease Teeth ruined by advanced caries, feline neck lesions etc. -

Feline Dentistry: Cats Are Not Small Dogs Matt Lemmons, DVM, DAVDC Medvet Indianapolis Carmel, IN
Basics for Practitioners: Oral Anatomy and Pathology Matt Lemmons, DVM, DAVDC MedVet Indianapolis Carmel, IN Dentistry is truly a branch of medicine and surgery. A strong knowledge of normal anatomy and pathology is cornerstone to adequate diagnosis and treatment of diseases of the oral cavity. The majority of oral related disease is inflammatory (periodontal disease) or traumatic (fractured teeth, orthopedic injuries) in nature. However other causes are not rare and need to be recognized. The basic dental unit is the tooth and surrounding periodontium. The tooth consists of the crown and root. The crown is covered in enamel and the root by cementum. Deep to the crown and cementum is the dentin. Dentin is a porous hard tissue which continuously grows toward the center of the tooth as long as the tooth is vital. Deep to the dentin is the pulp which consists of nerves, blood vessels, connective tissue, fibroblasts and odontoblasts. The periodontium is composed of the cementum, periodontal ligament, alveolar bone, and gingiva. The periodontal ligament serves to anchor the cementum to the alveolar bone, act as a shock absorber and aid in sensation. The gingiva is attached to the bone (attached gingiva), tooth by connective tissue and the most apical extent is not attached and is known as the free gingiva. The potential space between the free gingiva and tooth and ending apically at the sulcular epithelium is the gingival sulcus. In health this should be less than 3mm in depth in dogs and 1mm in cats. When addressing the teeth and periodontium, directional nomenclature is not similar to directional nomenclature of the rest of the body. -

A human frozen-tooth and/or a human frozen-bone block were put into the Zirconium oxide (ZrO2) ceramics vessel of the machine, and crushed for 1 minwith 20 saline- 3 ice blocks (1 © 1 © 1cm /block) at 12000 rpm of ZrO2 blade. The crushed granules were demineralized completely in2% HNO3 solution for 20 min, and rinsed incoldsaline. We named each biomaterial after the acid treatment and washing, demineralized dentin matrices (DDM), demineralized bone matrices (DBM). Five wisdom teeth (total wet volume: 10.0 g) were crushed, decalcified, and lyophilized. The distribution offreeze-dried DDM granules was fine granules (0.51.0 mm: 0.27 g), moderate (1.02.0 mm: 0.46 g), and large (2.05.0 mm: 0.64 g). The fine granules of human DDM or DBM were implanted into the subcutaneous tissue of 4 week-old nude mice, and theirtissue-inductive properties were estimated at 4 weeks after implantation histologically. -
Third Molar (Wisdom) Teeth
Third molar (wisdom) teeth This information leaflet is for patients who may need to have their third molar (wisdom) teeth removed. It explains why they may need to be removed, what is involved and any risks or complications that there may be. Please take the opportunity to read this leaflet before seeing the surgeon for consultation. The surgeon will explain what treatment is required for you and how these issues may affect you. They will also answer any of your questions. What are wisdom teeth? Third molar (wisdom) teeth are the last teeth to erupt into the mouth. People will normally develop four wisdom teeth: two on each side of the mouth, one on the bottom jaw and one on the top jaw. These would normally erupt between the ages of 18-24 years. Some people can develop less than four wisdom teeth and, occasionally, others can develop more than four. A wisdom tooth can fail to erupt properly into the mouth and can become stuck, either under the gum, or as it pushes through the gum – this is referred to as an impacted wisdom tooth. Sometimes the wisdom tooth will not become impacted and will erupt and function normally. Both impacted and non-impacted wisdom teeth can cause problems for people. Some of these problems can cause symptoms such as pain & swelling, however other wisdom teeth may have no symptoms at all but will still cause problems in the mouth. People often develop problems soon after their wisdom teeth erupt but others may not cause problems until later on in life. -

Lance Canines: an Illustrated Exploration I Would Like to Discuss a Recent Case of a Young Sheltie with a Couple of Dental Problems
Lance Canines: An Illustrated Exploration I would like to discuss a recent case of a young sheltie with a couple of dental problems. The first problem was a common one in shelties and is variably called lance canines, rostrally displaced maxillary canines or mesially displaced maxillary canines. Whatever name you choose, the problem is that the permanent maxillary canine teeth erupt pointing in the wrong direction. To understand a problem, you must first understand normal so I will review the normal relationship of the canine triad. The canine triad is composed of the maxillary lateral incisor and the canine teeth on one side and is depicted in Figure 1. In this picture, you can see that the crowns of the canine teeth are basically vertical. There is a large space between the maxillary lateral incisor and the maxillary canine and this space is known as a diastema. When the mouth is closed, the mandibular canine crown resides in the centre of the diastema so that it does not contact either of the other teeth in the triad. Figure 1: The normal canine triad. In affected shelties, one or both of the maxillary canines is malpositioned so that it is lying more horizontally. As such, the crown crosses the diastema and blocks the mandibular canine out as in Figure 2. Now on closure, the mandibular canine contacts the maxillary canine and is often forced to tip labially. Owners notice this because the mandibular canine then starts to catch on the upper lip. There is variability in the degree to which the maxillary canine is malpositioned. -

Wisdom Teeth Patient Information 1 About Your Wisdom Teeth
Wisdom Teeth Patient Information 1 About Your Wisdom Teeth What You Need to Know Also known as “third molars”, wisdom teeth don’t usually push through the gums until individuals reach their late teens, early 20’s or sometimes even older. Wisdom teeth are usually the last teeth to push through the gums. Most individuals have four wisdom teeth while some individuals have none. For many, there is not enough space at the rear of the jaw for wisdom teeth to easily push through the gums. When the jaw lacks space for the wisdom tooth to push through, the tooth becomes “impacted” or wedged in. Impacted wisdom teeth may not necessarily be a problem for some people while others may experience severe problems. If any wisdom teeth cause problems, they must be removed as soon as possible before the situation worsens. Sometimes, if it appears that the wisdom teeth will be difficult to remove, your dentist may refer you to an oral and maxillofacial surgeon. Depending on the shape and position of some wisdom teeth and the shape of the jaws, it’s occasionally recommendable that an oral and maxillofacial surgeon removes the wisdom teeth. When to Remove Teeth Your dentist will need to inspect your mouth, jaws and x-rays before discussing the diagnosis with you. It may be required that one or more of your wisdom teeth are removed, or other options are needed to be discussed. If there has been an infection, it may need to be treated before the surgery is performed. Sometimes, even if the wisdom tooth has caused problems, the situation may remedy once it has pushed through the gum.
