AbstractThe measurement of hydrogen–methane breath gases is widely used in gastroenterology to evaluate malabsorption syndromes and bacterial overgrowth. Laboratories offering breath testing provide variable guidance regarding oral hygiene practices prior to testing. Given that oral dysbiosis has the potential to cause changes in breath gases, it raises concerns that oral hygiene is not a standard inclusion in current breath testing guidelines. The aim of this study was to determine how a pre-test mouthwash may impact hydrogen–methane breath test results. Participants presenting for breath testing who had elevated baseline gases were given a chlorhexidine mouthwash. If a substantial reduction in expired hydrogen or methane occurred after the mouthwash, breath samples were collected before and after a mouthwash at all breath sample collection points for the duration of testing. Data were evaluated to determine how the mouthwash might influence test results and diagnostic status. In 388 consecutive hydrogen–methane breath tests, modifiable elevations occurred in 24.7%. Administration of a chlorhexidine mouthwash resulted in significantly (p ≤ 0.05) reduced breath hydrogen in 67% and/or methane gas in 93% of those consenting to inclusion. In some cases, this modified the diagnosis. Mean total gas concentrations pre- and post-mouthwash were 221.0 ppm and 152.1 ppm (p < 0.0001) for hydrogen, and 368.9 ppm and 249.8 ppm (p < 0.0001) for methane. Data suggest that a single mouthwash at baseline has a high probability of returning a false positive diagnosis. Variations in gas production due to oral hygiene practices has significant impacts on test interpretation and the subsequent diagnosis. The role of oral dysbiosis in causing gastrointestinal symptoms also demands exploration as it may be an underlying factor in the presenting condition that was the basis for the referral.

Pregnancy is a unique, exciting time in a woman's life, and there are so many changes going on in human body during pregnancy and mouth is no exception , so good oral hygiene is extremely important during pregnancy . Usually oral health is often the most neglected form of health during all stages of life & the most important cause for this neglection is lack of awareness among people & this problems also increases when a lady is pregnant because of mis-perceptions and mis-leading information in the society or due to lack of knowledge. But the fact is during pregnancy many complex physiologic changes occur in the women’s body, which can adversely affect oral health and in turn those oral health problems may lead to pregnancy outcomes like preterm birth or low birth weight. Proper oral care is of utmost importance during pregnancy to avoid these complications. Avoiding foods that may cause oral problems, proper brushing and flossing and having dental consultations on a regular basis are steps to ensure good oral health during pregnancy.

Since the 1990s numerous international experts have reported about the somatic complications of eating disorders including those having a dental and stomatological nature. Several reports emphasised that deformations in the oral cavity resulting from this grave nutritional disease typical of the young generation could already appear in the early stage and, therefore, dentists are among the first to diagnose them. Dentists are still often unaware of the importance of their role in multidisciplinary treatment. Even if they knew what the disease was about and recognised it on the basis of deformations in the oral cavity in time, their advice that their patients should brush their teeth more often would fail to eliminate the root cause of the problem. Not only the earliest possible treatment of the complications of the bingeing-purging mechanism and the maintenance of oral hygiene are important, but controlling and curing pathological habits with active participation of psychiatrists are also required to ensure full recovery. Due to the multidisciplinary nature of the disease, manifold communication is required. For this reason, publishing the dental ramifications of organic and systemic diseases at dental conferences and in technical journals, as well as providing information about oral complications of eating disorders for general practitioners and specialists are particularly important.

Elderly patients often find it challenging to remove plaque accumulated on the attachments of implant overdentures (IOD) using conventional cleaning instruments. Further, excessive plaque accumulation can lead to peri-implant diseases and occasionally to respiratory diseases. Therefore, here, we aimed to compare the effectiveness of waist-shaped interdental brushes (WIB) with that of straight-shaped ones (SIB) in plaque removal from the locator attachments of IOD. Twenty participants with two locator attachments retaining mandibular IOD participated in this study. After the baseline cleaning, the participants refrained from oral hygiene maintenance for 3 days. A dentist cleaned one of the attachments using the WIB and the other attachment using the SIB. The pre- and post-cleaning modified plaque index (mPLI) scores were recorded. Following another 3 days free from oral hygiene maintenance, the trained participants repeated the same cleaning procedure using the WIB and SIB. Pre- and post-cleaning mPLI scores were recorded. Regardless of the type of brush used, the post-cleaning mPLI scores were lower than the pre-cleaning ones. After the cleaning procedure, the overall mean mPLI score was lower in the WIB group than in the SIB group. The post-cleaning mPLI scores at the line-angles and on the axial surfaces of the attachments were also lower in the WIB group than in the SIB group. There was no difference in the cleaning effectiveness between the dentist and participants when they used the same type of interdental brush. The WIB was significantly more efficient in plaque removal than the SIB, especially at the line-angle sites.
