  • The Cementum: Its Role in Periodontal Health and Disease*
    THE JOURNAL OF PERIODONTOLOGY JULY, NINETEEN HUNDRED SIXTY ONE The Cementum: Its Role In Periodontal Health and Disease* by DONALD A. KERR, D.D.S., M.S.,** Ann Arbor, Michigan HE cementum is a specialized calcified tissue of mesenchymal origin which provides for the attachment of the periodontal fibers to the surface of the Troot. It consists of 45 to 50 per cent inorganic material and 50 to 55 per cent organic material with the inorganic material in a hydroxyl apatite structure. The primary cementum is formed initially by appositional growth from the dental sac and later from the periodontal membrane under the influence of cementoblasts. It is formed in laminated layers with the incorporation of Sharpey's fibers into a fibrillar matrix which undergoes calcification. Cementum deposition is a Continuous process throughout life with new cementum being deposited over the old cemental surface. Cementum is formed by the organiza• tion of collagen fibrils which are cemented together by a matrix produced by the polymerization of mucopolysaccharides. This material is designated as cementoid and becomes mature cementum upon calcification. The significance of the continuous deposition of cementum has received various interpretations. 1. Continuous deposition of cementum is necessary for the reattachment of periodontal fibers which have been destroyed or which require reorientation due to change in position of teeth. It is logical that there should be a continuous deposition of cementum because it is doubtful that the initial fibers are retained throughout the life of the tooth, and therefore new fibers must be continually formed and attached by new cementum.

  • Splitting of the Alveolar Process of the Lower Jaw
    SPLITTING OF THE ALVEOLAR PROCESS OF THE LOWER JAW. Peekskill, N. Y., Nov. 1, 1858. Messrs. Editors:—I send you the following communica­ tion, which I received from G. J. Fisher, M. D., of Sing Sing, New York, eminent as a surgeon in this part of the country, which you are at liberty to publish, if you think it of suffi­ cient interest to the dental profession, to be intitled to a place in your valuable journal. Respectfully, yours, E. D. Fuller, D. D. S. Sing Sing, N. Y., October 28, 1858. My Dear Friend :—I send you an account of a case which is so near the boundary line which separates dental from general surgery, that you may be interested with it, and even consider it worthy of insertion in some one of the journals devoted to your speciality. You are at liberty to use it as your own. Miss V., of Tarrytown, New York, a tall and comely lass, while engaged in juvenile sports with several children in the dining room, was tripped by her dress, causing her to fall, with great violence, striking the front teeth of the lower jaw against the margin of a mahogony table. On arising, she found the teeth driven into the mouth, and the jaw broken*. She applied to a physician, who directed her to a dentist for treatment. She came to Sing Sing the following day (Oct. 20th), and applied to Dentist Greenleaf, who, after examin­ ing the case, came to the conclusion that it was a little more surgical than dental, and therefore called me in to treat the injury.

The study describes two cases of this pathology occurring in several members of one family. This disease is inherited in an autosomal dominant or recessive way. Patients affected by this disease require a thorough diagnosis. In addition to basic medical history and dental examination, outside and inside oral cavity, additional study may be needed. The first reported case concerns a young mother with enlargement of gum tissue, which also appeared in her ​​children, mother and grandmother. In children, hyperplasia has caused the delay in the eruption of permanent teeth, diastema secondary, dental abnor- malities, changes in facial appearance and problems with oral hygiene. Similar changes were observed in the second case described a father and son for whom gingival hyperplasia was a serious problem, with respect to functional and aesthetic disturbances, deteriorating quality of life. The aim of this study is to present the problems associated with enlargement of the gums and the difficulty in the treatment this disease which is not always successful (Dent. Med.

  • Alveolar Process May Be Defined As That Part of the Maxilla and the Mandible That Forms and Supports the Sockets of the Teeth
    The alveolar process may be defined as that part of the maxilla and the mandible that forms and supports the sockets of the teeth. It developed with the eruption of teeth and disappears or lost after tooth extraction ALVEOLAR PROCESS BASAL BONE Alveolar (bone) process: is that part of the maxilla and the mandible that forms and supports the sockets of the teeth. Basal Bone. it is the bone of the facial skeleton which support the alveolar bone. There is no anatomical boundary between basal bones and alveolar bone. Both alveolar process and basal bone are covered by the same periosteum. In some areas alveolar processes may fuse or masked with jaw bones as in (1) Anterior part of maxilla (palatal). (2) Oblique line of the mandible. * Alveolar process is resorbed after extraction of teeth. Functions of alveolar bone – Houses and protects developing permanent teeth, while supporting primary teeth. – Organizes eruption of primary and permanent teeth. – Anchors the roots of teeth to the alveoli, which is achieved by the insertion of Sharpey’s fibers into the alveolar bone proper (attachment). – Helps to move the teeth for better occlusion (support). – Helps to absorb and distribute occlusal forces generated during tooth contact (shock absorber). – Supplies vessels to periodontal ligament. •DEVELOPMENT OF ALVEOLAR BONE •Near the end of the second month of fetal life, the maxilla as well as the mandible form a groove that is open towards the surface of the oral cavity. •Tooth germs develop within the bony structures at late bell stage. •Bony septa and bony bridge begin to form and separatethe individual tooth germs from one another, keeping individual tooth germs in clearly outlined bony compartments.

The alveolar bone comprises of two parts-alveolar bone proper which lines the socket of the tooth along with root, cementum and the periodontal ligament (periodontium) constitutes the Attachment apparatus; and the supporting alveolar bone. This attachment apparatus provides support to the tooth in the jaw as well as distributes forces generated by the teeth uniformly to the alveolar bone surrounding it. These functional changes are expressed by the process of ‘Bony remodelling’ in alveolar process. Therefore, this review provides an understanding of the anatomical aspect of alveolar bone and the molecular events that balance the formation and remodelling of alveolar bone.

Received 2 June, 2014; Accepted 8 October, 2014 The periodontium surrounds and supports the teeth and consists of four major components; gingiva, periodontal ligaments, cementum/dentin, and alveolar bone/lamina dura, with collective function of keeping the tooth in position despite varying changes and responses during mastication. A near-normal radiograph of periradicular tissues was used as the basis for evaluation of some common periradicular radiographic pathologies. Apical periodontitis was 70 (58.33%), alveolar abscess 32 (26.66%), and apical granulomas 15 (12.50%). A background anatomy of the periodontium is advocated as a precondition for accurate evaluation of periradicular pathologies. Key words: Periodontium, periradicular, pathology.
