I agree with the conclusion of Dr. Walter Loesche and colleagues that patients now have a choice in treatment options: surgery or extraction, or treatment based on an antimicrobial approach ("The Nonsurgical Treatment of Patients With Periodontal Disease: Results After Five Years," March JADA).
I have been treating patients with moderate to advanced periodontal disease since 1979 with an antimicrobial approach, and I know that teeth can be saved without surgery. While metronidazole and doxycycline are extremely useful toward this end, a successful reduction of periodontal pathogens can be accomplished without the use of systemic or local antibiotics. This is especially important when private-practice patients refuse antibiotics or cannot take them.
Metronidazole, for example, is contraindicated if a patient uses alcohol or is taking lithium or coumadin. Doxycycline is contraindicated if a patient takes digoxin, while antacids and gastroesophageal reflux disease medications may impair doxycycline absorption. And antibiotics, as we know, can decrease the efficacy of oral contraceptives.
Periodontal microorganisms can be reduced effectively with preliminary pocket irrigation using PVP-iodine,1 followed by full-mouth (not quadrant) scaling and root planing, or SRP,2,3 utilizing ultrasonics4,5 with an antiseptic irrigant such as chlorhexidine.6 The use of non-steroidal anti-inflammatory drugs, both topical and systemic, also has been shown to reduce the alveolar bone loss of periodontal disease.7 As Dr. Loesche indicated, during the active periodontal treatment phase, SRP should take place several times over a period of several months. I typically see patients every two to three weeks over a three-to four-month period.8
Then, to maintain low levels of bacteria commensurate with periodontal health, supportive periodontal treatments should be scheduled every three months. A rigorous but realistic home care program including pulsed oral irrigation9,10 is essential. This nonsurgical protocol is extremely effective in eliminating periodontal infection and inflammation and arresting moderate to advanced periodontitis without the use of antibiotics.
During both the treatment and the maintenance phase, Dr. Loesche makes no mention of any home care regimen or patient compliance. It has been my observation that nonsurgical periodontal treatment, either with or without antibiotics, will not be successful without a structured, detailed and compliant home care schedule that includes dietary recommendations or supplements.11,12
