COENZYME Q10: ANTIOXIDANT AS USEFUL TREATMENT ADJUNCT: A REVIEW: Part III
by- Dr.Vinayak Joshi
Periodontal Disease: Periodontal disease is primarily an inflammatory disease, which is initiated by the gram negative bacteria present in the plaque, which the in combination with certain host immune response leads to further progression. The presence of malnutrition or systemic disease acts as an adjunct to the primary factor i.e. plaque in the progression of the periodontal disease. It is well documented by various studies that deficiency of folic acid and vitamin A, C, and B complex along with poor oral hygiene results in increased periodontal inflammation. The activity of bacteria agglutinating glycoprotein in saliva is decreased in malnutrition, and this may promote enhanced formation of dental plaque and an overgrowth of potential perio-pathogens in malnutrition may contribute to periodontal disease occurrence. The malnutrition also affects the host response by suppressing production and cellular activation of cytokines, inverts the helper-suppressor T cell ratio, thereby affecting the natural defense mechanism. The CoQ10 are specifically utilized in energy production in cells. It has been shown that human gingival tissue contain coQ10 enzyme. The debate on the influence of CoQ10 in inflamed periodontal disease has been a long one. In 1960’s Tsunemitsu et al, and Matsumura et al studied effects of CoQ10 administration on hypercitricemia, showed that prolonged administration of CoQ10 alleviated the histopathologic alterations found in citrated rats. Lttarru et al 1971, found that gingival biopsies from patients having diseased periodontal tissues showed a deficiency of CoenzymeQ10 in control to those of the normal periodontal tissue which showed no deficiency. Nakamura et al in 1973 found that about 60% of the diseased gingival tissues showed deficiency of CoQ10 as compared to 20% of the control tissues. He concluded from the result that there was a deficiency of CoQ10 in the diseased gingival. However there have been studies conducted in animals and humans which showed the contrary results. Several studies have shown varying results like, Periodontal disease dose not affect CoQ10 levels, no affect of administration of CoQ10 on the specific activity or the mitochondrial enzymes in gingival, minimal or no affect of CoQ10 administration on plaque or gingival indices, pocket depth or periodontal disease. The effects of CoQ10 on the immune system of patients with periodontal disease were also studied. The T4/T8 ratio increased after 2 months of CoQ10 administration, while IgG levels increased significantly after 6months according to the study by Hanioka et al 1993. The affect of topical application of CoQ10 was studied by McRee et al 1993, and Hanioka et al 1994.The results of former suggested a very limited use effect after CoQ10 administration, while the results of the latter were inconclusive. Further Research: CoQ10 is known to improve the immune system by increasing the T4/T8 ratio and IgG levels. IgG is one of the important defense mechanism of gingival tissue as this immunoglobulin is found in high concentration in this tissue. CoQ10 is also known to improve the phagocytic activity of macrophages. CoQ10 can be combined with other host modulating agents like Sub antimicrobial Dosage of Doxycycline (e.g. Periostat), or Non steroidal anti-inflammatory agents (flubriprofen). The SDD is known to decrease the metalloproteinase enzymes in periodontal disease animal and human models. The CoQ10 which acts as a bioenergetic in the cellular function can act in combination with these drugs to give a combined or a synergistic affect. CoQ 10 could also be combined with other treatment modalities. Conclusion: The importance of CoQ10 as a bioenergetic in the cellular functions is established by previous research. The multifactor etiology in the periodontal disease makes the treatment a challenge. CoQ10 can be used an additional armor in the treatment protocol of this complex disease. The use of CoQ10 alone or in combination with other agents and treatment procedures is potential area of further research. Refrences:

RASHA RECOMMENDS .............
EVENTS:-
INDIA INTERNATIONAL DENTAL CONGRESS
The best of Indian Dentists will be meeting the World's best Dentists at the forthcoming India International Dental Congress [IIDC] to be held at Nehru Centre, Mumbai, India from February 22nd - 25th 2007. For the first time in India an offer to earn internationally recognized credits of 18 class hours from New York University - American Dental Association [ADA]. As these words are read, only a few months remain before the commencement of this international event. Such a convention takes years of planning and the collaboration of a multitude of professional organizations and associations, the generous participation of the international dental industry without whom the realization of a meeting of this magnitude would be difficult if not impossible. Never before seen in India, be sure not to miss the pre symposiums and the main symposium on the latest developments in dentistry that will take place daily throughout the four convention days. With the participation of eleven international experts, who will be here to share and discuss the latest technologies and recent materials. The dental exhibition will be the largest ever seen in India with outstanding pavilions showing the latest products on the dental market. Allow me to remind you to pre-register at the earliest, with the risk of disappointment due to lack of space. Many pre-conference courses and workshops are sold-out, however, you must absolutely reserve your place in advance with the number of available seats being limited.

In 1997, internet was considered as a very modern service in my dental school and we were not able to estimate to have such an advance information source in our rooms 24 hours of day! Technology provides faster than what we could imagine !!! At the same year (1997) the Food and drug Administration (FDA) in US approved the Erbium:YAG lasers for cavity preparation and I received that news by YAHOO ALERT, so decided to learn it earlier to prevent the LACK OF KNOWLEDGE, as what happened about INTERNET in our school. Till 2002 mostly did just laboratory researches with some BIG Nd:YAg lasers and working with lasers in my daily dental treatments was as a dream, but by entering to the RWTH Hospital, understood that it is more than 10 years, every body was using the LASERS for different applications daily and routine! as we use K-file! Now, on 2007 the year of CHANCE and LOCK, I thank god that I do 70% of my treatments without giving the stress of INJECTION to myself, my staff and my patients! Just now, there was a call from a patient, who came to me with an ABSCESS at the apex of tooth 21 (Upper left central). I made the cavity with Er:YAG laser (300 mJ, 15-20 Hz, 200 microseconds pulses) and sterilized the CANAL with Nd:YAG, after flaring that with normal finger files till ISO 45! The Nd:YAg setting was 1.5 Watt and 15 Hertz (Hz). The next step that I did is not possible to be done without laser! I entered the Nd:YAG fiber to the LESION at the soft tissue directly on the APEX area and patient although did not receive any anesthesia but did not feel at all when the full procedures were done and wondered at home how the ABSCESS is HIDED!!!
