Definitions
- This invention relates to endodontal surgery and particularly to instruments employed therein including absorbent pointed probes utilized as swabs in such as root canal surgery.
- the required treatment to arrest the continuing decay is likely a "root canal", known from its inclusion in the procedure.
- the decay of the tooth reaches the pulp, it likely becomes inflamed and may die. Involvement of the pulp usually results in root-end abscess and the associated infection may be passed by the blood stream to other parts of the body, producing inflammation, secondary abscess or other disease.
- Endodontic treatment if initiated immediately after injury or involvement of the pulp, can prevent formation of dental abscess, or if the abscess has developed, can usually eliminate the infection without extraction of the tooth.
- Removal of the pulp includes removal of the live tissue including the nerves and capillary vessels of the tooth. This procedure includes the cleaning of the hollow, canal-like portions of the tooth extending into the tooth's root, by which it is anchored into the jaw bone. Once the tooth, including the root canal, is completely cleaned, the hollow is filled with an air-tight sealer (commonly including medicaments to destroy microorganisms and promote healing) and the remaining cavity filled with the amalgam, or similar material.
- an air-tight sealer commonly including medicaments to destroy microorganisms and promote healing
- the process of adequately cleaning the root canal is a demanding one, requiring the absolute cleaning and sterilization of the canal, otherwise, a "dead cavity” may result.
- the "dead cavity” is one in which there is remaining tissue to decompose and cause further disease or abscess and may allow further decay within and adjacent the affected tooth including the surrounding periodontal tissue and occasioning the loss of supporting bone and, ultimately, the tooth.
- the meticulous process of the "root canal” begins with the removal of the diseased, decayed dentine by drilling and aspiration of that tissue and the underlying pulp.
- the capillaries and nerves contained in the interstices of the canals within the root are first loosened and scraped with narrow files. The canals are then cleaned and dried with absorbent dental points, the subject of the present invention.
- the adequate cleaning of the root canal requires the dentist to probe, scrape, clean and dry the full extent of the interstices of the canal. Subsequent to the cleaning and drying, a medicament is then applied, taking care that it too, reaches the full extent of the canal.
- Disease of the tooth once penetrating the dentine into the pulp, allows one or more of a variety of microorganisms and bacteria to quickly infiltrate the far reaches of the canal.
- the same type of absorbent dental point may be utilized to deliver the medicament to the extent of the canal as was used to dry it, being typically dipped into the medicament and then routed down into the canal.
- the treatment of the root canal is conducted to achieve the highest degree of asepsis as is possible. It is common for the dentist to utilize a dozen or more absorbent points during a procedure. On each occasion, the dentist must gauge the depth of the tip of point into the canal to ensure adequate cleaning, drying and medication to the particular depth desired. Commonly, the dentist has measured the depth of the canal (including branches and turns therein), or the several canals in the case of molars, with prior specialized instruments utilized in the drilling, scraping and filing process. Thus, it is important for the dentist to be reassured that the absorbent points are repeatedly inserted to the particular measured depths for selective treatment of the entire canal as the root canal procedure is conducted. Until the present invention, an absorbent dental point having the necessary measurement means has not been available to provide the assured, selective insertion of the absorbent dental point into a predetermined depth of the open root canal.
- Paper points as they are commonly called, are conventionally formed of special types of paper or synthetic materials exhibiting similar properties.
- the conventional paper point should exhibit a wicking action so as to imbibe exudates present in the root canal or pulp cavity.
- the paper point should also be capable of absorbing medicaments such that they may be subsequently delivered to the selected location of the root canal.
- the point must be sufficiently stiff to be insertable into the small opening of the root canal, yet sufficiently flexible to follow the tortious path of the canal to its end.
- An additional quality of a suitable paper point is lateral and longitudinal strength to withstand the manipulation of the tip as treatment is effected on the root canal. This lateral and longitudinal strength must persist though the paper point is saturated with exudate or medicament.
- U.S. Patent 2, 846,927 describes the manufacture of absorbent dental points of fibrous sheets of manila hemp, being tightly wound from a triangular sheet into an elongated, round shaft of slightly decreasing diameter from the held end to the operative or tip end.
- the principal objective of the present invention is to provide an absorbent dental point instrument which includes a graduated depth scale on the shaft of the instrument by which a dentist may readily identify the depth of insertion of the tip of the instrument.
- a still further object of the present invention is the inclusion of an inventive graduated depth scale on an absorbent dental point which promotes rapid and reliable reading of the depth of the tip of such a dental point.
- Figure 1 is a pictorial view, partially in section, of a tooth, illustrating the tooth structure and root canal into which the present invention is inserted during use.
- Figure 2 is an elevational view of the absorbent dental point of the present invention.
- Figure 3 is a sectional view of the embodiment of the embodiment of the present invention illustrated in Figure 2, taken along the line 3-3 in that view.
- Tooth 2 is anchored into gum 4 and adjacent jaw bone 6. Surrounding the tooth 2 is a periodontal membrane 8 which forms an envelope around the roots 10 of tooth 2. At the surface of the jaw bone, the periodontal membrane merges into the gum as at 12. Tooth 2 includes enamel 14, forming the hard, exterior of the tooth 2, and is composed mostly of the mineral calcium. Under enamel 14 is dentin 16 which forms the main core of tooth and it is composed generally of calcified tissue, calcium and phosphorous. The dentin 16 is highly sensitive and includes a labyrinth of tubules for the circulation of lymph.
- the central structure of the tooth 2 is the nerve or, more commonly, the pulp
- Pulp 18 is contains nerves, lymph, blood vessels and fibrous tissue.
- the pulp 18 is connected to the life systems through the pulp (or root) canal 20 which extends about 75 % of the length of the tooth, down into the root 10 via the pulp canal 24.
- the pulp canal terminates in apical foramen (holes) 26 at the tip of roots 10 and through which the nerves, blood vessels and lymph join their respective systems in the body.
- Lining the pulp cavity is a layer of odontoblasts, whose original function was to produce the dentine and which may be activated again by such as injury or tooth decay to again begin producing a secondary, protective layer of dentin.
- the present invention may be better appreciated as providing an instrument which can assist the dentist in removing all of the soft tissue and contained microorganisms from the canal and dry it such that a successful sealing and immobilization of the canal may be achieved.
- the present invention is embodied in an absorbent dental point 30
- Absorbent dental points are conventionally 28 mm to 30 mm in length, as measured from tip 32 to head end 34, and are available from a variety of sources such as Johnson & Johnson, Caulk, Kerr and Dident.
- Absorbent dental point 30 according to the present invention is illustrated as including a graduated depth scale 36 having indicators 38 disposed in ascending or descending relation on shaft 40 of point 30. Indicators may be placed upon point 30 in a variety of ways, well known in the art, including marking by dyes or inks or by such as scribing an imprint or indentation (e.g., engraving) into the surface of the shaft 40.
- scale 36 is made up of depth indicators 38, placed on point 30 in separated groupings, 42a and 42b.
- indicators 38 are spaced at locations indicating a depth (or operational length of point 30 below the specific indicator) of 18, 19, and 20 mm and
- the observation and distinguishing the depth value of a particular indicator 38 on scale 36 as determinative of the depth of tip 32 is readily accomplished. Since the depth indicators 38 of grouping 42a are at one millimeter increments, this grouping is readily differentiated from grouping 42b, in which lines are spaced in two millimeter increments. Likewise, since the numbers of depth indicators 38 within each grouping are limited to two and three indications (i.e., a different number), the distinguishing of the relevant indicator 38 on scale 34 and the accurate measurement of the depth of the canal is readily accomplished.
- the absorbent dental point of the present invention allows the dentist to quickly and reliably measure the depth of the root canal on each and every insertion of a point
- the effective cleaning, drying and coating of a canal may be reliably performed.
