背景:

う蝕(DC)は、歯周病菌の一種であり、う蝕(DC)の病因および進行において重要な役割を担っている。その定量化および同定は、疫学的および早期介入対策に役立つ可能性がある。

BACKGROUND: and play an important role in the etiopathogenesis and progression of dental caries (DC). Their quantification and identification may be helpful for epidemiological and early intervention measures.

目的:

我々は、う蝕のコロニー数およびう蝕の発生部位を評価し、う蝕の有病率と患者の年齢との相関を検討することを目的とした。

OBJECTIVES: We conducted the study to evaluate the colony counts of and with the location of DC and correlate their prevalence with the age of the patient.

材料と方法:

DC患者60名を対象とした。年齢により2群に分け、さらに各群をエナメル質、象牙質、歯髄へのDCの浸潤により3つのサブグループに分けた。スワブサンプルを採取し、Mitis Salivarius Bacitracin（MSB）寒天培地とMRS寒天培地を用いて細菌を分離した。透過光で照らされたプレート上のコロニーを手作業でカウントした。結果は統計的にまとめられ、分析された。

MATERIALS AND METHODS: The study population comprised 60 patients with DC. They were divided into two groups according to age, and each group was further divided into three subgroups based on involvement of enamel, dentin, and pulp by DC. The swab samples were collected, and organisms were isolated using Mitis Salivarius Bacitracin (MSB) Agar and MRS Agar. Manual counting of colonies on plates illuminated by transmitted light was done. Results were summarized and analyzed statistically.

結果:

う蝕有病率は小児で高く、女性で多いことがわかった。両群とも齲蝕罹患率は臼歯部が高く、咬合面/切歯面齲蝕が多かった。平均コロニー数（61.3％）と（63.4％）は、II群に比べI群で有意に高かった。両群とも平均コロニー数はエナメル質で多く、次いで象牙質、歯髄であった。一方、両群とも歯髄のコロニー数が多く、次いで象牙質、エナメル質の順であった。

RESULTS: The caries prevalence was found to be higher in children, with females being more affected. In both groups, posterior teeth were more affected, and occlusal/incisal surface caries were more common. The mean colony count of (61.3%) and (63.4%) was significantly higher in group I compared to group II. In both groups, the mean colony counts of were higher in enamel, followed by dentin and pulp. In contrast, in both groups, the mean colony counts of were higher in pulp, followed by dentin and enamel.

結論:

細菌のコロニー数は、特定の菌に対する特定の対策を講じることで、新たなう蝕の発生を予防するのに役立つと考えられる。

CONCLUSION: Bacterial colony counts may help in taking specific measures against specific organisms and thereby prevent the development of new carious lesions.
