None of the procedures managed to completely remove the Ca(OH)

from artificial grooves. There was no significant difference between the groups (p = 0.053). The scores were significantly lower in PUI group compared to the other techniques between NaOCl groups (p = 0.021).

Dual Rinse HEDP does not make a difference on elimination of Ca(OH)

. PUI is more efficient than both methods when NaOCl solution is used.

The prescription of antibiotics as an adjunct to mechanical periodontal therapy in patients with severe periodontitis is recommended; however, the side effects of antibiotics are a major concern. The aim of this study was to evaluate the efficacy of lycopene (Lyc) antioxidant gel versus minocycline hydrochloride microspheres (ARISTIN) as an adjunct to the nonsurgical treatment of periodontitis.

Three identical periodontal pockets/patient received root surface debridement followed by the random application of either ARISTIN, Lyc, or placebo gel (control, Ctrl). Clinical parameters, plaque index, bleeding on probing, probing pocket depth, and clinical attachment loss, were recorded at the baseline and after 30 days. Additionally, the levels of interleukin-8 (IL-8), matrix metallopeptidase 9, and tissue inhibitor of metalloproteinases 1 (TIMP1) in gingival crevicular fluid samples were assessed at the same time points.

Twenty-three patients with periodontitis completed the study. Both ARISTIN and Lyc treatments showed significantly greater gains in attachment (1.94 ± 1.33 and 1.72 ± 0.88, respectively) than the Ctrl treatment (1.04 ± 0.96). Compared with those in the Ctrl, only ARISTIN showed a significant reduction in IL-8 level, whereas TIMP1 levels were significantly upregulated in the Lyc gel and ARISTIN sites. The effect size estimation indicated that Lyc gel exhibited considerably greater efficacy than the Ctrl gel.

Lyc gel and ARISTIN offer almost equal improvement in both clinical and biochemical parameters of periodontitis.

Taiwan is facing a huge urban-rural gap in the human resources of dentists between cities and counties. Although the postgraduate year training program for dentists (PGYD) was implemented in Taiwan in 2010, the uneven distribution of dentists is still a serious problem. The purpose of this study was to evaluate the distributions of overall dentists and dental training institutions and their dentists (so-called institutional dentists) in each city and county in 2019 to further analyze the regional distributions of overall dentists and institutional dentists in Taiwan.

This study collected the numbers of dentists, dental training institutions, and institutional dentists in each city and county in 2019 for evaluating the regional distributions of dentists and institutional dentists in Taiwan.

The numbers of dentists and institutional dentists in municipalities were significantly higher than those in non-municipalities in Taiwan, respectively. The coefficient of variation was greatest for dentists in the single-system institutions (1.72) and program-management institutions (1.87). The coefficients of correlation between the dentist index and institutional dentist index were R

 = 0.9805 (

 < 0.001) for municipalities, R

 = 0.4523 (

 < 0.01) for non-municipalities, and R

 = 0.7691 (

 < 0.001) for nationwide.

The dentist manpower and dental training institutions are concentrated in municipalities of Taiwan. The quantitative and qualitative improvement of collaborating institutions in the PGYD system may have an influence on the distribution of new-entry dentists and contribute to establishment of an effective regional dental health care service.

Bruxism affects the stomatognathic system and causes tissue damage by the excessive jaw movements. The purpose of this study was to evaluate the effects of sleep bruxism on jaw bone density, mineralisation and morphology by comparing bruxers and non-bruxers.

60 bruxers and 60 non-bruxers (control) patients were included in the analysis. Cortical width at the gonion (GI), at the mental foramen (MI), at the antegonion (AI), the panoramic mandibular index (PMI), the mandibular cortical index (MCI) and antegonial notch depth (AND) were measured bilaterally on 120 panoramic radiographs. The measurements were evaluated for repeatability, correlation with age, gender and correlation between the variables.

A significant association was observed between cortical shape (MCI) and bruxism status (p = 0.012). The MI was significantly different between the bruxers and non-bruxers (p = 0.006). There was a significant but weak correlation between the MI value and age in bruxers and the control (p = 0.003, p = 0.04). check details The AI was not associated with bruxism status and did not vary by age or gender (p > 0.05). The AND was higher in bruxers than non-bruxers (p = 0.001). Male bruxers had a significantly higher AND value than female bruxers (p = 0.001). The GI was higher in male bruxers (p = 0.001).

Defects in the endosteal margin of the cortex and cortical thickening in the mental region were detected in bruxer patients. Furthermore, AND was increased in bruxers. Tiny bone peaks accompanied the cortical thickening seen in the gonial region. Male bruxer patients had higher GI and AND values than female bruxers.
