The purpose of this study was to determine if Moxibustion stimulus influence on the circulation in the sacral area.
In the first phase of this study, the influence of indirect Moxibustion stimulus (using‹SEN-NEN-KYU›) on the amount of blood flowing to the sacrum was investigated using laser Doppler Perfusion Imager PeriScan PIM II.
Significant increase in the amount of blood flow in radial directions were observed around the area where Moxibustion was applied. Immediately after the stimulus, significant differences in the amount of blood flow were observed within 2.5cm to the right and left and 1.5cm above and below the stimulated spot.
With increasing time after the Moxibustion stimulus, the amount of blood flow gradually decreased concentrically returning to the original state over time. However, the amount of blood flow at the Moxibustion spot was significantly higher than the original state 32 minutes and 52 seconds after the Moxibustion treatment.
Increased blood flows to pressure ulcers area induced by Moxibustion stimulus are considered to restrict or arrest the progress of pressure ulcers (according to Stage I of the International Association for Enterostomal Therapy (IAET) classification) on in-home care.

OBJECTIVE: The objective of this study is to investigate the eruption pattern and root resorption of the bovine anterior dentition in relation to growth-related parameters based on dental maturity. METHODS: A cross-sectional study was conducted on 110 bovine anterior mandibles by using standard radiography, cone-beam computed tomography (CBCT), and actual measurements. We determined the relationships between the stages of dental maturity by using a modification of Demirjian's method and various growth-related parameters, such as the activity of the root-resorbing tissue and mobility of the deciduous teeth. The correlation of growth-related parameters with interdental spacing and distal unusual root resorption (DRR) of the deciduous fourth incisor was assessed. The cause of mesial unusual root resorption (MRR) of the deciduous fourth incisor was determined on the basis of the arrangement of the permanent third incisor. RESULTS: An independent t-test and chi-square test indicated significant differences in growth-related parameters associated with dental arch length discrepancy and factors related to the shedding of deciduous teeth between the low and high dental maturity groups. The samples with interdental spacing and DRR showed a larger sum of mesiodistal permanent crown widths and higher dental maturity than did the respective controls. Samples with MRR tended to show a lingually rotated distal tip of the adjacent tooth crown. CONCLUSIONS: Dental maturity has relevance to the interdental spaces and unusual root resorption of mixed dentition. The position of the adjacent tooth crown on CBCT may be correlated with the occurrence of unusual root resorption of the incisor.

OBJECTIVE: The purpose of this study was to clarify the effects of continuous force application for extrusive tipping movement and occlusal interference on periapical root resorption in the rat mandibular first molar. METHODS: We constructed an appliance comprising a titanium screw implant with a cobalt-chromium post as the anchorage unit and a nickel-titanium closed coil spring (50 cN) as the active unit. Force was applied on the mandibular left first molar of rats for 8 (n = 10) and 15 days (n = 10; experimental groups), with the tooth in occlusion. Five rats were included as a non-treated control group to examine the body effect of the appliance. Active root resorption lacunae, identified using tartrate-resistant acid phosphatase, were evaluated in terms of the length, depth, and area. RESULTS: The rat mandibular first molars were mesially tipped and extruded in the occlusal direction. This mesio-occlusal tipping movement and occlusion resulted in the formation of a compression zone and active root resorption lacunae in the distoapical third of the distal roots. However, there was no significant difference in the amount of root resorption between the two experimental groups. The control group did not exhibit any active root resorption lacunae. CONCLUSIONS: Periapical root resorption was induced by continuous extrusive tipping force and occlusal interference in rat mandibular molars. These data suggest that we orthodontists had better take care not to induce occlusal interference during our orthodontic treatment.
