![]() The epithelial covering of the col consists of the marginal gingiva of the adjacent teeth, and because it is not keratinized, this area is much more fragile and vulnerable to periodontal breakdown. Attached gingiva is resistant to masticatory forces and is always keratinized but the col varies in depth and width, depending on the size and form of the contacting tooth surfaces and is not keratinized. The interdental embrasure can be pyramidal or have a “col” shape. The interdental gingiva occupies the gingival embrasure, which is the interproximal space between the teeth, apical to the tooth contact. The interdental area is the part of gingiva which extends in between two teeth up to the contact point. Furcations, root and pocket concavities: hardest areas to clean Contact Area: large, small/wide, narrowĦ. Embrasure sizes: tight, moderate, wide / long, shortģ. In order to better evaluate interdental cleaners, the anatomical characteristics that make this area difficult for patients to clean and for professionals to treat must be highlighted ( Figs. The PerioTwist interdental cleaner and delivery device has been developed to address the shortcomings of floss and the existing floss alternatives. The floss alternatives used to clean the interdental space have both benefits and limitations. Dexterity also diminishes with age, necessitating a floss alternative. Furthermore, salivary flow decreases, allowing for more food and plaque accumulation. Embrasures and interdental spaces become larger and a thin dental floss can no longer adequately clean this space. Teeth typically do NOT erupt but the receding gingiva gives that impression. According to the ADA, only 12-40% of Americans floss daily 20% never floss.1,2 More than a third of people surveyed would rather be doing unpleasant chores than flossing their teeth daily: 14% would rather clean the toilet 9% would rather sit in gridlock traffic for an hour, and 7% would rather listen to small children crying on a plane.Īlternatives to dental floss have recently been introduced to address problems and limitations of dental floss (non-compliance, shedding, tearing, complicated instructions for using both, preferably clean, hands, and inefficient cleaning of larger embrasures and deeper pockets, indentations and furcations).Īs individuals age, they are perceived to “get longer in the tooth”. The drawback of dental floss, however, is that most people dislike the process. ![]() ![]() The first dental floss patent was granted to J&J in 1898. ![]() Levi Spear Parmly in 1815, is the benchmark interdental cleaning device. Neither the bristles of the toothbrush nor mouthwash can effectively access and clean this area an alternate device must be used to clean the interdental space.ĭental floss, invented by Dr. In fact, the most difficult, complicated, and expensive therapy that a dentist performs daily is caused by the pathology of the interdental space. Its anatomy provides the perfectly inaccessible environment for dental plaque to accumulate and fester, thereby causing great harm to both teeth and periodontium. The interdental space is the most neglected area of the mouth, yet the most vulnerable. A new innovative interdental cleaner and delivery device called a “PerioTwist”™ is also introduced. There are many floss alternatives that are currently available that are much easier to use than floss, which would not only encourage more compliance, but may even clean more efficiently. ![]() The interdental space is the most vulnerable yet most neglected area of the mouth because of its anatomy and the fact that most people hate to floss. ![]()
