Effect of irradiation with CO2 laser on dog periodontal tissues. 1984

J F Barahona

The effects of CO2 laser irradiation on the premolar and molar vestibular gingiva of twenty-one mongrel dogs were studied. The relationship between the irradiated energy, damage due to the radiation and the healing process were observed macroscopically and microscopically. Bleeding was not observed during radiation. The ray did not reach the bone, and damages to the soft tissue could heal easily at less than 10 J irradiation. When the irradiation energy was increased higher than 20 J the healing process was significantly delayed, and irreversible damage to the tooth, partial loss of the alveolar crest and sequestra formation were observed in some cases.

UI	MeSH Term	Description	Entries
D007834	Lasers	An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
