Theories Of Eruption Of Teeth
There are three main theories for how teeth erupt: root formation theory, bone remodeling theory, and periodontal ligament (PDL) formation theory. The root formation theory states that tooth eruption is caused by root growth pushing the tooth upwards. The bone remodeling theory claims bone growth around the tooth pushes it upwards. The PDL formation theory argues that PDL fibers and fibroblasts contracting provide the main force for eruption. Ultimately, the document concludes that tooth eruption is best explained by the force theory, which is that all three theories—root formation, bone remodeling, and PDL formation—work together to erupt teeth.
486 theories of tooth eruption
This document discusses various theories of tooth eruption, including the root elongation theory, bone remodeling theory, periodontal ligament contraction theory, vascular pressure theory, and dental follicle theory. It provides details on each theory and their fallacies. Tooth eruption is a multifactorial process influenced by root formation, bone remodeling, the dental follicle, hydrostatic pressure in tissues, and other factors. No single theory fully explains the process, and tooth eruption likely involves elements from several theories working together.

Tooth eruption
The document discusses the phases of tooth eruption and theories of tooth eruption. It describes three phases of tooth eruption: 1) the preeruptive phase where the tooth germ moves within the jaw bone, 2) the eruptive or prefunctional phase where the root forms and the tooth emerges into the mouth, and 3) the functional or post-eruptive phase where the tooth reaches the bite and the roots continue to develop. Several theories for the mechanism of tooth eruption are mentioned, including the roles of vascularity, pressure changes, root formation, bone remodeling, the dental follicle, and the periodontal ligament.
Eruption Theory..root elongation theory
The document discusses several theories of tooth eruption, including the root elongation theory. According to this theory, the apical growth of roots results in axial forces that cause eruption. However, this theory was rejected for several reasons, including that teeth move farther than root growth, eruption does not coincide with root growth onset, and teeth without roots can still erupt. The document concludes that while root growth may play a role once the eruption pathway is established, it does not appear to be the primary driver of eruption.
tooth eruption
This document discusses tooth eruption and the mechanisms of tooth eruption. It describes the three phases of tooth eruption: preeruptive, eruptive, and functional phases. The preeruptive phase involves the tooth germ moving outward and upward/downward within the alveolar process due to jaw growth. The eruptive phase begins with root formation and ends when the tooth reaches the occlusal plane. The functional phase occurs after the tooth erupts and accommodates further root and jaw growth. Several theories are presented to explain the mechanism of tooth eruption, including vascularity, pressure changes, root formation, bone remodeling, the dental follicle, and the periodontal ligament.
Tooth eruption
Tooth eruption is the movement of developing teeth through the bone and gums to emerge in the mouth. It occurs in three phases: pre-eruptive, eruptive, and functional. In the pre-eruptive phase, the tooth germ moves outward and upward/downward as the jaws grow in length, width, and height. The eruptive phase begins with root formation and ends when the tooth reaches the biting surface, involving both movement within and above the bone. Finally, in the functional phase the tooth remains in the mouth as the root and jaws continue growing.
Tooth eruption
The document discusses the development of dentition from initiation through emergence and maturation. It describes the pre-eruptive, per-functional, and functional phases of tooth development. Eruption involves movement of the tooth from its developmental position into the mouth. Primary and permanent molars have two stages of eruption. Eruption rates differ by tooth type and involve surrounding tissues degrading and the tooth emerging.
Tooth eruption and shedding - complete package
Tooth eruption and shedding is a complex process involving three phases: pre-eruptive, eruptive, and post-eruptive. There are several theories for the mechanism of eruption, with the most accepted being the dental follicle theory involving bone remodeling. Primary teeth typically erupt in a set sequence between 6 months to 2.5 years and are later shed and replaced by permanent teeth according to Nolla's stages of eruption. Problems can occur during eruption like teething, eruption cysts, or ectopic/non-eruption of teeth which are typically managed through non-pharmacological or pharmacological means. Knowledge of normal eruption timing is important for treating dental issues in children

This document discusses tooth eruption, including its definition, phases, and mechanisms. It begins by defining tooth eruption as the movement of developing teeth through bone and gum tissue to emerge in the mouth. It then describes the three phases of eruption: pre-eruptive (tooth development below gum), eruptive (root formation and emergence), and post-eruptive (teeth in function). The mechanisms of eruption involve bodily movement and growth changes. Teeth can be categorized based on their eruptive characteristics as continuously growing, continuously extruding, or continuously erupting.
Eruption sequence of primary teeth
The document summarizes the sequence of eruption of primary teeth. It begins by defining tooth eruption as the movement of a tooth from development within the jaws to its functional position in the oral cavity. It then outlines the order of eruption of primary teeth as central incisors, lateral incisors, first molars, canines, and second molars. Finally, it briefly discusses the importance of primary teeth for functions like chewing, speech development, and guiding permanent teeth into place.
3 shedding future
Primary teeth, also known as baby teeth, are naturally shed and replaced by permanent teeth according to a predictable pattern. Anterior primary teeth are shed from the lingual root surface inward, while posterior primary teeth are initially resorbed at interradicular areas before being fully replaced. Genetic and local factors like pressure from erupting permanent teeth influence the timing and rate of shedding. Histologically, specialized cells called odontoclasts resorb dental tissues while the pulp and periodontium degenerate in a programmed manner. Ankylosed primary teeth fuse to bone and may become submerged, interfering with permanent tooth eruption. Retained primary teeth fail to shed by the usual age due to issues like missing permanent successors
Erruption 2017
Tooth eruption involves three phases: pre-eruptive, eruptive, and post-eruptive. In the pre-eruptive phase, tooth germs develop and move within the jaw as it grows. The eruptive phase begins with root formation and ends when teeth reach the occlusal plane. Teeth emerge through the gums via bone resorption. In the post-eruptive phase, teeth continue moving axially and mesially to accommodate jaw growth and wear. Several theories attempt to explain eruption mechanisms, including root formation, bone remodeling, dental follicle activity, and periodontal ligament traction.
ERUPTION AND SHEDDING
This document discusses the eruption and shedding of teeth. It defines eruption as the process of a tooth moving through the alveolar bone into the oral cavity. Shedding is defined as the physiological process that eliminates the deciduous dentition. The document outlines the different patterns of tooth movement during eruption, including pre-eruptive, eruptive, and post-eruptive movement. It also discusses the histological changes that occur in the surrounding tissues to facilitate tooth eruption and shedding.

Tooth eruption ppt
Tooth eruption is a complex process involving the movement of teeth from their development position in the jawbone to their functional position in the mouth. The key structures involved are the root follicle, periodontal membrane, and crown follicle. Multiple theories have been proposed to explain the mechanism of eruption, including root formation theory, vascular pressure theory, and dental follicle theory. Clinically, natal and neonatal teeth as well as eruption cysts can occur during the eruption process.

Eruption power point
1. Tooth eruption is the movement of tooth germs from their developmental sites until they emerge into the oral cavity and reach occlusion. This movement occurs through various stages, including pre-eruptive movement before emergence and eruptive movement after emergence.
2. During pre-eruptive movement, tooth germs move in response to jaw growth through mechanisms like bodily movement and eccentric growth. They also move in relation to each other through the gobernacular canal.
3. Eruptive pre-functional movement occurs after tooth emergence and involves axial and other movements to bring teeth into occlusion. Eruptive post-functional movement allows teeth to compensate for jaw growth and occlusal wear throughout life
Eruption
The document discusses the phases and mechanism of tooth eruption. It describes the three phases as:
1) Pre-eruptive phase where tooth germs grow and the jaw bones remodel to make space.
2) Eruptive phase where the roots form and the teeth move from their crypts to their functional positions through bone resorption and deposition guided by the periodontal ligament fibers.
3) Post-eruptive phase where teeth continue moving to accommodate growth and compensate for wear.
The key theories discussed for the mechanism of eruption are: bone remodeling around the crypt, the role of the dental follicle in providing cells for bone formation and resorption, the eruptive forces
New rich text document (3)
This document discusses the mechanism of tooth eruption through reviewing various theories and clinical observations. It is proposed that tooth eruption involves alveolar bone remodeling regulated by the dental follicle, requiring bone resorption in the direction of eruption and bone formation on the opposite side. While root formation accommodates eruption, it does not cause it. Eruption speeds vary at different stages, from slow intraosseous movement to faster pre-occlusal eruption to very slow post-occlusal eruption. Understanding local bone metabolism regulation is key to managing eruption clinically.
Tooth eruption n shedding
This document discusses tooth eruption and shedding. It begins by describing the formation of the dental lamina during embryonic development, from which the primary teeth and permanent successors develop. It then covers the developmental stages of teeth, the theories of eruption, and the phases of eruption including pre-eruption, eruption, and post-eruption. It also provides the chronology of human dentition development and shedding of teeth. In summary, it provides a comprehensive overview of tooth development from the embryonic stage through eruption and shedding.

Tooth eruption and shedding involve complex movements of teeth through bone and tissue as the primary and permanent dentitions develop and replace each other. There are three phases of tooth eruption - pre-eruptive, eruptive, and post-eruptive - which involve remodeling of bone and surrounding tissues. The primary teeth are shed and replaced by the permanent teeth due to progressive root resorption caused by the erupting permanent tooth buds applying pressure and inducing resorption. The periodontal ligament contraction theory is currently the most accepted explanation for the mechanism of tooth eruption.
shedding of the teeth.PPT
Tooth eruption is a continuous process involving three phases - preeruptive, eruptive, and posteruptive. During the eruptive phase, teeth emerge through the gums in four stages: root formation, movement, penetration, and occlusal contact. Primary teeth are eventually shed and replaced by permanent teeth during the transition from primary to mixed to permanent dentition. Tooth eruption involves constant movement of developing crowns, root formation, bone remodeling by the dental follicle, and traction from the periodontal ligament. Posteruptive movement further accommodates jaw growth and compensates for tooth wear through alveolar bone formation.
Tooth Eruption Dr Mona Denewar
This document discusses tooth eruption, including:
1. Tooth eruption involves the axial movement of teeth from their developmental position in the jaw bone to their functional position in occlusion.
2. There are three phases of eruption - pre-eruptive, eruptive, and post-eruptive phases. The eruptive phase involves both intraosseous and extraosseous stages as the tooth moves from within the bone to reaching the occlusal plane.
3. Several theories have been proposed to explain the mechanism of tooth eruption, including root formation theory, bone remodeling theory, periodontal ligament traction theory, and dental follicle theory. However, it is now believed
Eruption
Tooth eruption involves three phases:
1. The pre-eruptive phase involves tooth germ development and movement within the jaw bone.
2. The eruptive phase is when the tooth emerges into the mouth through the gums and reaches the bite.
3. The post-eruptive phase occurs after the tooth has reached the bite, and involves minor movements like accommodating jaw growth and bite wear.
Tooth eruption is guided by several theories centered around root formation, bone remodeling, the dental follicle, and ligament and blood vessel forces, but is likely multifactorial. Clinical considerations for eruption include early or delayed timing.
Eruption of teeth ( Hesham Dameer )
Tooth eruption is a complex process involving three phases: preeruptive, prefunctional eruptive, and functional. During the preeruptive phase, developing teeth move within the jaw bone through bodily movement, tilting, or drifting as the jaws grow. In the prefunctional eruptive phase, teeth move from within the bone to their functional positions through both intraosseous and extraosseous movement. The final functional phase involves minor axial movements to maintain occlusion throughout life. Tooth eruption is believed to be mediated by cellular signaling between the dental follicle and surrounding bone, leading to selective bone resorption and deposition to guide eruption.

TRAUMA FROM OCCLUSION
When occlusal forces exceed the adaptive capacity of the tissues, tissue injury results the resultant injury is termed as trauma from occlusion.
delayed eruption in dentistry.pdf
This document discusses delayed tooth eruption (DTE). It defines various types of DTE and outlines the normal process of tooth eruption. It identifies several potential local and systemic causes of DTE, including supernumerary teeth, ankylosed deciduous teeth, premature loss of deciduous teeth, arch length deficiencies, nutritional deficiencies, endocrine disorders, and genetic syndromes. The document also provides details on the typical chronology and sequence of primary and permanent tooth eruption.
Alveolar bone
This document provides an overview of alveolar bone. It discusses the development, anatomy, histology, radiographic features, and pathologies of alveolar bone. Alveolar bone forms the bony housing for teeth and provides attachment for the periodontal ligament. It develops during fetal growth via intramembranous ossification. Anatomically, it consists of cortical plates and inner cancellous bone with trabeculae. Histologically, it is composed of osteoblasts, osteocytes, and osteoclasts. Common pathologies involving alveolar bone loss include periodontal disease, trauma from occlusion, and systemic factors like osteoporosis.
Trauma From Occlusion.pptx
This document discusses trauma from occlusion (TFO), which refers to injury to the periodontium resulting from excessive occlusal forces. It defines key terms, classifies TFO, and describes the stages of tissue response and role of occlusion in periodontal disease pathogenesis. Several human and animal studies are summarized that investigated the relationship between occlusal forces and periodontal disease, generally finding that excessive forces alone do not cause attachment loss but may alter the pathway of destruction in the presence of plaque. The document provides an overview of TFO and its relationship to periodontal disease.
