A 22-year-old female presented with intermittent epigas- tric pain for 6 d after swallowing a broken toothbrush. The swallowed toothbrush could not be removed from the second portion of the duodenum by endoscopy. Laparotomy revealed a perforation in the anterior wall of the duodenal bulb. The toothbrush was removed via the perforation which was debrided and closed. There were no postoperative complications.展开更多

We decided to study the effectiveness of natural toothbrush in prevention of dental caries and plaque formation. Methods: This analytic, semi-experimental clinical trial included 390 individuals. Subjects were divided into 3 groups: using natural toothbrush, using artificial toothbrush and using both natural and artificial toothbrush. The plaque index and DMFT was assessed at the beginning of the study until 1 year. ANOVA, Kruskal Wallis, LSD, Paired t-test, chi square, Fisher exact and Mc-Nemar tests were used for data analysis. Results: The plaque index in all three groups showed a mean reduction of 0.71. The mean DMFT in the samples before intervention was 8.38 ± 4.14 and increased to 9.1 ± 4.56. At the end of the study, the lowest plaque index was observed in the group using both the natural and artificial methods. During one year follow-up, the plaque index decreased 1.16, 0.83, and 0.21 degrees in the first, second and third groups. Conclusion: The increase in DMFT in the group that used artificial toothbrush was more than other groups. Thus, use of natural toothbrush leads to a decrease in growth rate of DMFT. Therefore natural toothbrush can be used for the cleaning of teeth and prevention of dental caries.展开更多

This study aims to assess toothbrushing techniques using a technical and physical model, clarifying how children and pre-adults learn to brush their teeth. Materials and Methods: Data were recorded from 23 participants, both male and female of various ages, using a proposed electronic toothbrush equipped with X-Y-Z axes pathways. The data, collected before and after training experiments, were processed with MATLAB to generate plots for the three axes. Results: The study revealed that most parameter values, such as Mean Difference Between Amplitudes (MAV, 6.00), Wilson Amplitude (WAMP, 179.419), and Average Amplitude Coupling (AAC, 1.270), decreased from before to after the experiments. Furthermore, the average overall epoch lengths (AVG) showed a 75% reduction in movement amplitude between the two experiments. Conclusion: Dentist observations indicated which brushing methods were acceptable or not. Analytical values suggest that individuals learn the toothbrushing technique effectively, and medical observations clearly demonstrate the success of the proposed method.展开更多

They constitute an important resource permanently exploited by the populations of the Kpakpamè District. This research aims to identify the different plants used by the populations of Kpakpamè as toothbrushes and their therapeutic values. To reach this objective, documentary research, direct observation, and data collection from hundred and ninety-five (195) people randomly chosen but following well-defined criteria were carried out. The consensus value for plant parts noted CPP, is calculated to find the number of times a plant part is cited (Px) divided by the total number of times all parts are cited (Pt), and also to determine the most frequent collection sites, the consensus value for collection sites is calculated. In total, nineteen (19) species have been cited and grouped into nineteen (19) genera and eleven (11) families. Pseudocedrella kostchyi and Zanthoxylum zanthoxyloides are the most cited species with respective citation frequencies of 0.27 and 0.14. They come more from village lands with a Consensus value for collection sites (CCS) of 0.49 and are used to cure about twelve (12) diseases including dental caries (33.33%). These species are now almost threatened with extinction according to the IUCN. It is therefore important to develop safeguarding and sustainable conservation actions for these plant species. This work has made it possible to identify the different species used by the populations of the Kpakpamé district as toothbrushes despite the urbanization and modernization of this locality formerly known in the Zou department as the most endogenous region. Several studies have focused on the diversity of plants used for oral hygiene and even the phytochemical properties of the species identified without taking into account the phytodistrict, social and perceptions of local populations.展开更多

The aim in this study was to investigate if a toothbrush with incorporated blue light used in daily oral care can reduce dental plaque and gingival inflammation. An 8-week single-blinded randomized controlled clinical study including 48 subjects compared effects of toothbrushes with/without 450 nm blue LED light emission, on clinical parameters (plaque index, gingival index, bleeding on probing), and on inflammatory markers in saliva and gingival crevicular fluid. Significant reductions in dental plaque and gingival inflammation (p < 0.001), and in some inflammatory markers (p ≤ 0.05), matrix metalloproteinase (MMP)-8, tissue inhibitor metalloproteinase inhibitor (TIMP)-1, interleukin (IL)-1β and interleukin (IL)-8, were detected within both groups from baseline to follow-up. For all subjects dental plaque was reduced with 57%, and a reduction in gingival inflammation was demonstrated by a decrease in gingival index (GI) with 46% and in bleeding on probing (BOP) with a decrease of 15%. No significant differences were found between the groups at a level of p = 0.05. However, the amount of plaque was reduced by 62% in the blue light group and 51% in the control group, a difference established at a level of p = 0.058. A toothbrush with a 450 nm LED did not show any statistical significant adjunctive effect of toothbrushing regarding reduction in measurements of dental plaque and gingival inflammation.展开更多
