| ==Prevention==
| | {{Periodontitis}} |
| Daily [[oral hygiene]] measures to prevent periodontal disease include:
| | {{CMG}} |
| *[[toothbrush|brushing]] properly on a regular basis (at least twice daily), with the patient attempting to direct the toothbrush bristles underneath the gum-line, so as to help disrupt the bacterial growth and formation of subgingival plaque and calculus.
| |
| *[[flossing]] daily and using interdental brushes (if there is a sufficiently large space between teeth), as well as cleaning behind the last tooth in each quarter.
| |
| *using an antiseptic [[mouthwash]]. [[Chlorhexidine gluconate]] based mouthwash or [[hydrogen peroxide#Therapeutic use|hydrogen peroxide]] in combination with careful oral hygiene may cure gingivitis, although they cannot reverse any attachment loss due to periodontitis. (Alcohol based mouthwashes may aggravate the condition).
| |
| *regular dental check-ups and professional teeth cleaning as required. Dental check-ups serve to monitor the person's oral hygiene methods and levels of attachment around teeth, identify any early signs of periodontitis, and monitor response to treatment.

| Typically dental hygienists (or dentists) use special instruments to clean (debride) teeth below the gumline and disrupt any plaque growing below the gumline. This is a standard treatment to prevent any further progress of established periodontitis. Studies show that after such a professional cleaning (periodontal debridement), bacteria and plaque tend to grow back to pre-cleaning levels after about 3-4 months. Hence, in theory, cleanings every 3-4 months might be expected to also prevent the initial onset of periodontitis. However, analysis of published research has reported little evidence either to support this or the intervals at which this should occur.<!--

| Instead it is advocated that the interval between dental check-ups should be determined specifically for each patient between every 3 to 24 months.<!--

| Nonetheless, the continued stabilization of a patient's periodontal state depends largely, if not primarily, on the patient's [[oral hygiene]] at home if not on the go too. Without daily [[oral hygiene]], periodontal disease will not be overcome, especially if the patient has a history of extensive periodontal disease.

| [[Image:Generalized perio -touched up.jpg|450px|thumb|left|This section from a panoramic [[radiograph|X-ray film]] depicts the teeth of the lower left quadrant, exhibiting generalized severe bone loss of 30-80%. The '''red line''' depicts the existing bone level, whereas the '''yellow line''' depicts where the bone was originally, prior to the patient developing [[periodontal disease]]. The '''pink arrow''', on the right, points to a ''furcation involvement'', or the loss of enough bone to reveal the location at which the individual roots of a molar begin to branch from the single root trunk; this is a sign of advanced periodontal disease. The '''blue arrow''', in the middle, shows up to 80% bone loss on tooth #21, and clinically, this tooth exhibited gross mobility. Finally, the '''peach oval''', to the left, highlights the aggressive nature with which periodontal disease generally affects mandibular incisors. Because their roots are generally situated very close to each other, with minimal [[Commonly used terms of relationship and comparison in dentistry|interproximal]] bone, and because of their location in the mouth, where plaque and calculus accumulation is greatest because of the pooling of [[saliva]], mandibular anteriors suffer excessively. The '''split in the red line''' depicts varying densities of bone that contribute to a vague region of definitive bone height.]] | |
| If good [[oral hygiene]] is not yet already undertaken daily by the patient, then twice daily [[toothbrush|brushing]] with daily [[flossing]], [[mouthwash]]ing and use of an interdental brush needs to be started. Technique with these tools is very important. Aged persons may find that use of these interdental devices more necessary and easier, since the gaps between the teeth may become larger.

|
| A dental hygienist or a [[periodontist]] can use professional scraping instruments, such as scalers and currettes to remove bacterial plaque and [[Calculus (dental)|calculus]] (formerly referred to as tartar) around teeth and below the gum-line. There are devices that use a powerful ultra-sonic vibration and irrigation system to break up the bacterial plaque and calculus. Local anesthetic is commonly used to prevent discomfort in the patient during this process.
| | ==[[Periodontitis pathophysiology|Pathophysiology]]== |
|
| |
|
| It is difficult to induce the body to repair bone that has been destroyed due to periodontitis. Much depends on exactly how much bone was lost and the architectural configuration of the remaining bone. '''Vertical defects''' are those instances of bone loss where the height of the bone remains somewhat constant except in the localized area where there is a steep, almost ''vertical'' drop. '''Horizontal defects''' are those instances of more generalized bone loss, resulting in anywhere from mild to severe loss of initial bone height.
| | ==[[Periodontitis causes|Causes]]== |
| Sometimes [[bone graft]]ing [[surgery]] may be tried, but this has mixed success. Bone grafts are more reliable in instances of vertical defects, where there might be a sufficient "hole" within which to place the added bone. Horizontal defects are rarely if ever able to be grafted properly, as there is nowhere to secure the bone.
| |
|

|
| Dentists sometimes attempt to treat patients with periodontitis by placing tiny wafers dispensing antibiotics underneath the gumline in affected areas. However, the general scientific consensus is that antibiotic treatment is of minimal value in treating bone loss due to periodontitis. It may help to recover about one millimeter of bone, but it is questionable if this is of significant therapeutic value.

|
| Alternatively, regular subgingival flushing with an anti-calculus composition can dissolve subgingival calculus (tartar) thus facilitating natural healing without surgery. This process is widely used for supragingival tartar via tartar-control toothpastes. Subgingival application of an anti-calculus composition requires a subgingival syringe or an oral irrigator.
| | ==[[Periodontitis epidemiology and demographics|Epidemiology and Demographics]]== |
|
| |
|
| One such anti-calculus composition (Periogen) contains Sodium Tripolyphosphate, Tetrapotassium Pyrophosphate, [[sodium bicarbonate]], [[Citric Acid]] and [[sodium fluoride]].
| | ==[[Periodontitis risk factors|Risk Factors]]== |
|
| |
|
| In the composition, tetrapotassium pyrophosphate (TKPP) is a cleaning agent designed to clear away [[biofilm]]s in order to facilitate chemical access to [[calculus]]. [[sodium tripolyphosphate]] (STPP) acts as the anti-calculus agent, activated by Sodium Fluoride (.04%), providing a chelating action on the structure of the calculus.
| | ==[[Periodontitis natural history, complications and prognosis|Natural History, Complications and Prognosis]]== |
|
| |
|
| Sodium Bicarbonate and Citric Acid are product activators which assist in dissolving the composition in water for periodontal delivery via a subgingival syringe or oral irrigator with a periodontal tip.

| == Assessment and prognosis == | | ==Treatment== |
| Dentists or dental hygienists "measure" periodontal disease using a device called a [[periodontal probe]]. This is a thin "measuring stick" that is gently placed into the space between the gums and the teeth, and slipped below the gum-line. If the probe can slip more than 3 millimetres length below the gum-line, the patient is said to have a "gingival pocket" around that tooth. This is somewhat of a misnomer, as any depth is in essence a pocket, which in turn is defined by its depth, i.e., a 2 mm pocket or a 6 mm pocket. However, it is generally accepted that pockets are self-cleansable (at home, by the patient, with a toothbrush) if they are 3 mm or less in depth. This is important because if there is a pocket which is deeper than 3 mm around the tooth, at-home care will not be sufficient to cleanse the pocket, and professional care should be sought. When the pocket depths reach 5, 6 and 7 mm in depth, even the hand instruments and cavitrons used by the dental professionals cannot reach deeply enough into the pocket to clean out the bacterial plaque that cause gingival inflammation. In such a situation the pocket or the gums around that tooth will always have inflammation which will likely result in bone loss around that tooth. The only way to stop the inflammation would be for the patient to undergo some form of gingival surgery to access the depths of the pockets and perhaps even change the pocket depths so that they become 3 or less mm in depth and can once again be properly cleaned by the patient at home with his or her toothbrush.

|
| If a patient has 5 mm or deeper pockets around their teeth, then they would risk eventual tooth loss over the years. If this periodontal condition is not identified and the patient remains unaware of the progressive nature of the disease then, years later, they may be surprised that some teeth will gradually become loose and may need to be extracted, sometimes due to a severe infection or even pain.
| | ==Case Studies== |
| | | [[Periodontitis case study one|Case #1]] |
| According to the Sri Lankan Tea Labourer study, in the absence of any oral hygiene activity, approximately 10% will suffer from severe periodontal disease with rapid loss of attachment (>2 mm/year). 80% will suffer from moderate loss (1-2 mm/year) and the remaining 10% will not suffer any loss.<!--
