Arrested eruption of the permanent lower second molar. (1/342)
The incidence of retention/impaction of the permanent lower second molar (M2inf) lies between 0.6/1000 and 3/1000. Therefore, the purpose of the present study was to investigate the craniofacial morphology, the frequency of dental anomalies and the inclination of the affected M2inf and the adjacent first molar in patients with arrested eruption of M2inf. The overall goal was to elucidate the aetiology of arrested tooth eruption and to present the characteristics of these patients in order to improve diagnosis and treatment planning. Radiographic material (profile radiographs and orthopantomograms) from 19 patients (nine females and 10 males; 13-19 years of age at the time of referral) were analysed. The ages of the patients when profile radiographs were taken for cephalometric analysis varied from 8 to 16 years. The study shows that this group of patients, compared with a reference group, had an increased sagittal jaw relationship (Class II). Specifically, the mandibular prognathism was less, the mandibular gonial angle smaller, the mandibular alveolar prognathism enlarged and the maxillary incisor inclination less than in the reference group. Furthermore, this group of patients had a more frequent occurrence of morphological tooth anomalies, such as root deflections, invaginations, and taurodontism. However, none of the patients with arrested eruption of M2inf had agenesis of the lower third molar. The study did not reveal an association between the degree of inclination of the M2inf and that of the first molar in the same region. The results of this investigation show that conditions such as the craniofacial morphology and deviations in the dentition are associated with arrested eruption of M2inf. Therefore, it is important to evaluate these conditions in future diagnosis and treatment planning of patients with arrested eruption of M2inf. (+info)Imaging of a Stafne bone cavity: what MR adds and why a new name is needed. (2/342)
Stafne bone cavities are asymptomatic radiolucencies seen at the angle of the mandible. Although plain films are often sufficient for diagnosis, confirmatory imaging is needed in atypical cases. We describe the MR imaging findings of a Stafne bone cavity, describe the contents, explain why a new name is needed, and discuss the relative merits of different radiologic techniques for establishing this diagnosis. (+info)Efficacy of mandibular topical anesthesia varies with the site of administration. (3/342)
This study compared the threshold of pain sensitivity in the anterior mandibular mucobuccal fold with the posterior. This was followed by a comparison of the reduction of needle insertion pain in the anterior mucobuccal fold and the pterygo-temporal depression by either topical anesthesia or nitrous oxide inhalation. The pain threshold was determined by an analgometer, a pain-measuring device that depends on pressure readings; additionally, pain caused by a needle inserted by a normal technique was assessed using a visual analog scale (VAS). The threshold of pain was significantly lower in the incisor and canine regions than in the premolar and the molar regions (P < 0.001). Compared to a placebo, topical anesthesia significantly reduced the pain from needle insertion in the mucobuccal fold adjacent to the mandibular canine (P < 0.001), but did not significantly reduce pain in the pterygotemporal depression. The addition of 30% nitrous oxide did not significantly alter pain reduction compared to a control of 100% oxygen. These results suggest that topical anesthesia application may be effective in reducing the pain of needle insertion in the anterior mandibular mucobuccal fold, but may not be as effective for a standard inferior alveolar nerve block. The addition of 30% nitrous oxide did not lead to a significant improvement. (+info)Mandibular shape and skeletal divergency. (4/342)
Pre-treatment lateral cephalograms of 41 skeletal Class I girls aged 11 to 15 were divided according to MP-SN angle: lower than 28 degrees (hypodivergent, 10 girls), between 31 and 34 degrees (normodivergent, 18 girls), or larger than 37 degrees (hyperdivergent, 13 girls). The mandibular outlines were traced and digitized, and differences in shape were quantified using the elliptic Fourier series. Size differences were measured from the areas enclosed by the mandibular outlines. Shape differences were assessed by calculating a morphological distance (MD) between the size-independent mean mathematical reconstructions of the mandibular outlines of the three divergency classes. Mandibular shape was different in the three classes: large variations were found in hyperdivergent girls versus normodivergent girls (MD = 4.61), while smaller differences were observed in hypodivergent girls (MD versus normodivergent 2.91). Mean size-independent mandibular shapes were superimposed on an axis passing through the centres of gravity of the condyle and of the chin. Normodivergent and hyperdivergent mandibles differed mostly at gonion, the coronoid process, sigmoid notch, alveolar process, posterior border of the ramus, and along the mandibular plane. A significant size effect was also found, with smaller mandibles in the hyperdivergent girls. (+info)Neural modulation of inflammatory reactions in dental tissues incident to orthodontic tooth movement. A review of the literature. (5/342)
This article reviews the current knowledge of the biological aspects of dental tissue changes incident to orthodontic tooth movement. The inflammatory nature of these tissue changes was first recognized in the early 1970s, and since then a number of morphological and quantitative investigations have been published in support of this view. The studies dealing with vascular and cellular dental tissue changes, as well as those concerned with inflammatory mediators present at sites of orthodontic tooth movement are systematized and presented accordingly. Special emphasis is placed upon the role of the sensory nerve fibres and their neuropeptides in the control, and development of an inflammatory process, i.e. their role in tooth movement. (+info)Osteometry of the mandible performed using dental MR imaging. (6/342)
BACKGROUND AND PURPOSE: On cross-sectional and panoramic reformatted images from axial (dental) CT scans of the mandible it may be difficult to identify the inferior alveolar neurovascular bundle (IANB) in patients lacking a clear-cut bony delimitation of the mandibular canal. Dental MR images are comparable to dental CT scans, which directly show the IANB; however, measurements of length may not be reliable owing to susceptibility artifacts and field inhomogeneities in the oral cavity. Therefore, the accuracy of length measurements on dental MR images was compared with that on dental CT scans and direct osteometry. METHODS: Dental T1-weighted MR imaging using a high-resolution turbo gradient-echo sequence and dental CT were performed in six anatomic specimens. The axial scans were reformatted as panoramic and cross-sectional reconstructions on a workstation and characteristic cross sections were obtained from all mandibles. The longest axis in the bucco-lingual and apico-basal directions, the distances from the top of the mandibular canal to the top of the alveolar ridge and from the bottom of the mandibular canal to the base of the mandible, and the diameter of the bone cortex at the alveolar ridge were measured with direct osteometry on the cross sections and compared with measurements on corresponding MR and CT reformatted images. RESULTS: The correlation between direct osteometry and dental MR and CT was strong, except for the bone cortex diameter at the top of the alveolar ridge, where only a moderate correlation was found. Means of comparable length measurements were not significantly different among the three methods. CONCLUSION: The accuracy of length measurements in the jaw bones obtained using dental MR is comparable to that of dental CT and is not significantly different from direct osteometry. Thus, dental MR is a potential alternative to CT for dental imaging. (+info)A 5-year post-operative review of secondary alveolar bone grafting in the Yorkshire region. (7/342)
The objective of this study was to determine the quality of secondary alveolar bone grafting in the Yorkshire region, and consisted of a retrospective review of patients case notes and radiographs at five surgical units within the Yorkshire region. The subjects were 109 patients who had secondary alveolar bone grafting between 1.9.91. and 31.8.96. The quality of outcome was assessed using a four-point radiographic scale from occlusal radiographs taken at least 3 months post-operatively: Grade 1 = > 75 per cent bony in-fill, Grade 2 = 50-75 per cent bony in-fill, Grade 3 = < 50 per cent bony in-fill, and Grade 4 = no bony bridge. The radiographic assessment scale was assessed for reliability: inter-examiner weighted kappa = 0.622-0.715 and intra-examiner = 0.818-0.943. Grade 1 results were achieved in 63.2 per cent patients receiving orthodontic expansion and in 40 per cent without expansion before grafting. The four-point radiographic scale described is a useful tool in assessing alveolar bone grafting, Orthodontic expansion. (+info)Blood vessel response to pan-endothelium (RECA-1) antibody in normal and tooth loaded rat periodontal ligament. (8/342)
Immunolabelling of the normal rat molar periodontal ligament (PDL) with RECA-1 antibody, an endothelial cell surface marker, demonstrated the endothelium in the different categories of blood vessels. The intensity of immunolabelling was similar for venous capillaries (VC), post-capillary-sized venules (PCV), and collecting venules (CV). Arterial capillaries (AC) and terminal arterioles (TA) showed a different response, both having a high intensity of endothelium and smooth muscle cell labelling, whether they were located in the PDL or alveolar bone. An experimental, continuous loading of approximately 100 g was applied unilaterally to the mandibular molars for 10 minutes. In the PDL apical compression zone this load resulted in a loss of RECA-1 immunolabelling of the VC, PCV, and CV. Adjacent to the alveolar crest, where shear and tension loads were judged to have occurred, there was enhanced immunoreactivity of VC, PCV, and CV. In the loaded PDL, the AC and TA, irrespective of their location in the ligament or bone, showed strong immunofluorescence of their endothelium and the enveloping smooth muscle layer. Vessel and PDL immunofluorescence were analysed with standardized grey scale densitometry, and the data subjected to ANOVA. Comparison between individual vessel means showed significant differences (P < 0.05). Control teeth showed no immunostaining difference between the coronal and apical region vessels, whereas in the loaded teeth the overall cervical vessel endothelium had a significantly higher value than the apical vessel endothelium (P < 0.001). These findings demonstrate that the endothelium of this microvascular bed can undergo significant immunoreactivity changes when exposed to short-term, continuous, tooth loading. (+info)The alveolar process is the curved part of the jawbone (mandible or maxilla) that contains sockets or hollow spaces (alveoli) for the teeth to be embedded. These processes are covered with a specialized mucous membrane called the gingiva, which forms a tight seal around the teeth to help protect the periodontal tissues and maintain oral health.
The alveolar process is composed of both compact and spongy bone tissue. The compact bone forms the outer layer, while the spongy bone is found inside the alveoli and provides support for the teeth. When a tooth is lost or extracted, the alveolar process begins to resorb over time due to the lack of mechanical stimulation from the tooth's chewing forces. This can lead to changes in the shape and size of the jawbone, which may require bone grafting procedures before dental implant placement.
The maxilla is a paired bone that forms the upper jaw in vertebrates. In humans, it is a major bone in the face and plays several important roles in the craniofacial complex. Each maxilla consists of a body and four processes: frontal process, zygomatic process, alveolar process, and palatine process.
The maxillae contribute to the formation of the eye sockets (orbits), nasal cavity, and the hard palate of the mouth. They also contain the upper teeth sockets (alveoli) and help form the lower part of the orbit and the cheekbones (zygomatic arches).
Here's a quick rundown of its key functions:
1. Supports the upper teeth and forms the upper jaw.
2. Contributes to the formation of the eye sockets, nasal cavity, and hard palate.
3. Helps shape the lower part of the orbit and cheekbones.
4. Partakes in the creation of important sinuses, such as the maxillary sinus, which is located within the body of the maxilla.
The mandible, also known as the lower jaw, is the largest and strongest bone in the human face. It forms the lower portion of the oral cavity and plays a crucial role in various functions such as mastication (chewing), speaking, and swallowing. The mandible is a U-shaped bone that consists of a horizontal part called the body and two vertical parts called rami.
The mandible articulates with the skull at the temporomandibular joints (TMJs) located in front of each ear, allowing for movements like opening and closing the mouth, protrusion, retraction, and side-to-side movement. The mandible contains the lower teeth sockets called alveolar processes, which hold the lower teeth in place.
In medical terminology, the term "mandible" refers specifically to this bone and its associated structures.
Alveolar macrophages are a type of macrophage (a large phagocytic cell) that are found in the alveoli of the lungs. They play a crucial role in the immune defense system of the lungs by engulfing and destroying any foreign particles, such as dust, microorganisms, and pathogens, that enter the lungs through the process of inhalation. Alveolar macrophages also produce cytokines, which are signaling molecules that help to coordinate the immune response. They are important for maintaining the health and function of the lungs by removing debris and preventing infection.
Pulmonary alveoli, also known as air sacs, are tiny clusters of air-filled pouches located at the end of the bronchioles in the lungs. They play a crucial role in the process of gas exchange during respiration. The thin walls of the alveoli, called alveolar membranes, allow oxygen from inhaled air to pass into the bloodstream and carbon dioxide from the bloodstream to pass into the alveoli to be exhaled out of the body. This vital function enables the lungs to supply oxygen-rich blood to the rest of the body and remove waste products like carbon dioxide.
A tooth socket, also known as an alveolus (plural: alveoli), refers to the hollow cavity or space in the jawbone where a tooth is anchored. The tooth socket is part of the alveolar process, which is the curved part of the maxilla or mandible that contains multiple tooth sockets for the upper and lower teeth, respectively.
Each tooth socket has a specialized tissue called the periodontal ligament, which attaches the root of the tooth to the surrounding bone. This ligament helps absorb forces generated during biting and chewing, allowing for comfortable and efficient mastication while also maintaining the tooth's position within the jawbone. The tooth socket is responsible for providing support, stability, and nourishment to the tooth through its blood vessels and nerves.
The periodontal ligament, also known as the "PDL," is the soft tissue that connects the tooth root to the alveolar bone within the dental alveolus (socket). It consists of collagen fibers organized into groups called principal fibers and accessory fibers. These fibers are embedded into both the cementum of the tooth root and the alveolar bone, providing shock absorption during biting and chewing forces, allowing for slight tooth movement, and maintaining the tooth in its position within the socket.
The periodontal ligament plays a crucial role in the health and maintenance of the periodontium, which includes the gingiva (gums), cementum, alveolar bone, and the periodontal ligament itself. Inflammation or infection of the periodontal ligament can lead to periodontal disease, potentially causing tooth loss if not treated promptly and appropriately.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Alveolar bone loss refers to the breakdown and resorption of the alveolar process of the jawbone, which is the part of the jaw that contains the sockets of the teeth. This type of bone loss is often caused by periodontal disease, a chronic inflammation of the gums and surrounding tissues that can lead to the destruction of the structures that support the teeth.
In advanced stages of periodontal disease, the alveolar bone can become severely damaged or destroyed, leading to tooth loss. Alveolar bone loss can also occur as a result of other conditions, such as osteoporosis, trauma, or tumors. Dental X-rays and other imaging techniques are often used to diagnose and monitor alveolar bone loss. Treatment may include deep cleaning of the teeth and gums, medications, surgery, or tooth extraction in severe cases.
A bone fracture is a medical condition in which there is a partial or complete break in the continuity of a bone due to external or internal forces. Fractures can occur in any bone in the body and can vary in severity from a small crack to a shattered bone. The symptoms of a bone fracture typically include pain, swelling, bruising, deformity, and difficulty moving the affected limb. Treatment for a bone fracture may involve immobilization with a cast or splint, surgery to realign and stabilize the bone, or medication to manage pain and prevent infection. The specific treatment approach will depend on the location, type, and severity of the fracture.
Fracture healing is the natural process by which a broken bone repairs itself. When a fracture occurs, the body responds by initiating a series of biological and cellular events aimed at restoring the structural integrity of the bone. This process involves the formation of a hematoma (a collection of blood) around the fracture site, followed by the activation of inflammatory cells that help to clean up debris and prepare the area for repair.
Over time, specialized cells called osteoblasts begin to lay down new bone matrix, or osteoid, along the edges of the broken bone ends. This osteoid eventually hardens into new bone tissue, forming a bridge between the fracture fragments. As this process continues, the callus (a mass of newly formed bone and connective tissue) gradually becomes stronger and more compact, eventually remodeling itself into a solid, unbroken bone.
The entire process of fracture healing can take several weeks to several months, depending on factors such as the severity of the injury, the patient's age and overall health, and the location of the fracture. In some cases, medical intervention may be necessary to help promote healing or ensure proper alignment of the bone fragments. This may include the use of casts, braces, or surgical implants such as plates, screws, or rods.
A hip fracture is a medical condition referring to a break in the upper part of the femur (thigh) bone, which forms the hip joint. The majority of hip fractures occur due to falls or direct trauma to the area. They are more common in older adults, particularly those with osteoporosis, a condition that weakens bones and makes them more prone to breaking. Hip fractures can significantly impact mobility and quality of life, often requiring surgical intervention and rehabilitation.
A femoral fracture is a medical term that refers to a break in the thigh bone, which is the longest and strongest bone in the human body. The femur extends from the hip joint to the knee joint and is responsible for supporting the weight of the upper body and allowing movement of the lower extremity. Femoral fractures can occur due to various reasons such as high-energy trauma, low-energy trauma in individuals with weak bones (osteoporosis), or as a result of a direct blow to the thigh.
Femoral fractures can be classified into different types based on their location, pattern, and severity. Some common types of femoral fractures include:
1. Transverse fracture: A break that occurs straight across the bone.
2. Oblique fracture: A break that occurs at an angle across the bone.
3. Spiral fracture: A break that occurs in a helical pattern around the bone.
4. Comminuted fracture: A break that results in multiple fragments of the bone.
5. Open or compound fracture: A break in which the bone pierces through the skin.
6. Closed or simple fracture: A break in which the bone does not pierce through the skin.
Femoral fractures can cause severe pain, swelling, bruising, and difficulty walking or bearing weight on the affected leg. Diagnosis typically involves a physical examination, medical history, and imaging tests such as X-rays or CT scans. Treatment may involve surgical intervention, including the use of metal rods, plates, or screws to stabilize the bone, followed by rehabilitation and physical therapy to restore mobility and strength.
A spinal fracture, also known as a vertebral compression fracture, is a break in one or more bones (vertebrae) of the spine. This type of fracture often occurs due to weakened bones caused by osteoporosis, but it can also result from trauma such as a car accident or a fall.
In a spinal fracture, the front part of the vertebra collapses, causing the height of the vertebra to decrease, while the back part of the vertebra remains intact. This results in a wedge-shaped deformity of the vertebra. Multiple fractures can lead to a hunched forward posture known as kyphosis or dowager's hump.
Spinal fractures can cause pain, numbness, tingling, or weakness in the back, legs, or arms, depending on the location and severity of the fracture. In some cases, spinal cord compression may occur, leading to more severe symptoms such as paralysis or loss of bladder and bowel control.
