Do You Want A Copy of George Washington's False Teeth?

Description

While George Washington did have dental troubles for much of his life, the story that his false teeth were made of wood is false. George Washington had dentures made of many materials, including human teeth. In the 18th century, it was common practice for dentists to purchase teeth from poor people for use in dentures or tooth transplants. 1784, Washington purchased nine teeth for 122 shillings, which is less than a third of the payment advertised to poor white Americans. They were likely enslaved people living at Mount Vernon.

The STL files are available for you to print the dentures for yourself.

Abstract

Background

The biomechanical behavior of implant-supported titanium and zirconia full-arch fixed dental prosthesis (FAFDP) frameworks require further investigation.

Purpose

Strains transferred by implant-supported titanium (Ti) and zirconia (Zr) FAFDP frameworks were analyzed.

Materials and Methods

Maxillary 14-unit FAFDPs supported by 6 implants and 12-unit FAFDPs supported by 4 implants were tested. One-piece frameworks were fabricated by computer-aided design/computer-aided manufacturing. Four groups were divided (n = 3): G1, Ti-6 implants; G2, Zr-6 implants; G3, Ti-4 implants; G4, Zr-4 implants. A 250 N single-point load was applied on the second premolar. A three-dimensional digital image correlation system recorded framework and maxilla model surface deformation.

Results

The following strains (μS) averaged over the length of the second premolar were calculated: frameworks, G1 (321.82 ± 111.29), G2 (638.87 ± 108.64), G3 (377.77 ± 28.64), G4 (434.18 ± 132.21); model surface, G1 (473.99 ± 48.69), G2 (653.93 ± 45.26), G3 (1082.50 ± 71.14), G4 (1218.26 ± 230.37). Zirconia frameworks supported by 6 implants (G2) presented higher surface strains (P < .05). FAFDPs with titanium frameworks transferred significantly lower strains to the supporting maxilla when 6 implants were used (G1) (P < .05). Both framework materials transferred similar strains when supported by 4 implants (G3 and G4) (P > .05).

Conclusions

Zirconia frameworks supported by 6 implants showed higher strains. FAFDPs supported by 6 implants transferred less strains to the supporting maxilla, irrespective of framework material.

Comparison of periodontal evaluation by cone-beam computed tomography, and clinical and intraoral radiographic examinations

Oral Radiology

pp 1–11

Abstract

Objectives

Cone-beam computed tomography (CBCT) has been widely used in many fields of dentistry. However, little is known about the accuracy of CBCT for evaluation of periodontal status. The objective of this study was to compare and correlate periodontal assessments among CBCT, clinical attachment loss (CAL) measurement, and periapical (PA)/bitewing (BW) radiography.

Methods

Eighty patients (28 males, 52 females; age range, 19–84 years) from the University of Texas School of Dentistry at Houston were evaluated retrospectively. Measurements were taken on the central incisors, canines, and first molars of the right maxilla and left mandible. CAL was extracted from periodontal charts. The radiographic distance from the cementum–enamel junction (CEJ) to the alveolar crest was measured for tooth mesial and distal sites on PA/BW and CBCT images using MiPacs software and Anatomage Invivo software, respectively. One-way ANOVA and Pearson analysis were performed for statistical analyses.

Results

The CEJ–crest distances for CBCT, PA/BW, and CAL were 2.56 ± 0.12, 2.04 ± 0.12, and 2.08 ± 0.17 mm (mean ± SD), respectively. CBCT exhibited larger values than the other two methods (p < 0.05). There were highly significant positive correlations among CBCT, PA/BW, and CAL measurements at all examined sites (p < 0.001). The Pearson correlation coefficient was higher for CBCT with CAL relative to PA/BW with CAL, but the difference was not significant (r = 0.64 and r = 0.55, respectively, p > 0.05).

Conclusions

This study validates the suitability of CBCT for periodontal assessment. Further studies are necessary to optimize the measurement methodology with CBCT.

Effect of conventional irrigation and photoactivated disinfection on Enterococcus faecalis in root canals: An in vitro study

Abstract   Aims: A study was done to evaluate the antimicrobial efficacy of sodium hypochlorite (NaOCl) and photoactivated disinfection (PAD) on Enterococcus faecalis.   Settings and Design: Random sampling, in-vitro study. Subjects and Methods: Access opening and biomechanical preparation were performed on fifty freshly extracted mandibular second premolars. The specimens were sterilized; 15 μm of E. faecalis was inoculated into each canal and incubated at 36°C for 24 h. Later, specimens were randomly divided into two groups of fifty each and following procedures was carried out: (i) conventional irrigation with 2.25% NaOCl (ii) PAD using diode laser, and toluidine blue photosensitizer. Samples were collected from each canal using sterile paper points which were deposited in brain heart infusion broth, and microbiological evaluation was carried out. Statistical Analysis Used: Student's t-test was used to find the significant difference in the reduction of colony forming unit (CFU) between the groups. Results: The mean CFUs of the two groups showed statistically significant difference (P = 0.001). Improved antibacterial efficacy was seen with PAD group compared to conventional NAOCL irrigation. Conclusions: NaOCl alone was not effective in eliminating E. faecalis completely from the root canals. PAD compared to conventional irrigation showed the best results in removing E. faecalis from root canals. Balakrishna N, Moogi P, Kumar G V, Prashanth B R, Shetty NK, Rao KR.

Abstract

Objective

To evaluate the accuracy of CBCT images for bone/implant interface diagnosis in comparison to periapical radiographs.

Study Design

Titanium implants were inserted in 74 bovine rib blocks in intimate contact to the bone walls, and with a gap of 0.125 mm (simulating a failure in the osseointegration process). Periapical radiographs were taken with conventional film, and CBCT scans were acquired with i-CAT (0.2mm and 0.125mm voxel) and Kodak (0.2mm and 0.076mm voxel) units. Three examiners evaluated the images using a 5-point scale. Diagnostic accuracy was analyzed through sensitivity, specificity, and the area under the ROC curve (AUC) with 95% confidence intervals (CI). Intra- and inter-examiner agreements were analyzed through Kendall's concordance test.

Results

Intra- and inter-examiner agreements showed satisfactory results. The greatest accuracy was observed with conventional radiographs (AUC = 0.963 / CI 95% = 0.891-0.993). I-CAT 0.125mm images showed good accuracy (AUC = 0.885 / CI 95% = 0.790-0.947), with no significant difference compared to conventional radiography. Kodak images had high specificity and low sensitivity, presenting more false-negative results.

Conclusion

Conventional radiographs showed the highest accuracy for bone/implant interface diagnosis. However, CBCT scans (i-CAT 0.125 mm voxel), if available or if performed for pre-surgical assessment of another implant site, may provide similar accuracy.
