These guidelines include changes in personal protective equipment and, under some guidelines, the institution of a fallow period after any aerosol-generating procedure (AGP). This study aimed to investigate the effect of both ventilation and 4-handed dentistry in clinical practice with patients undergoing supportive periodontal therapy (SPT) by air polishing, ultrasonic and hand instrumentation in a closed operatory. We studied 34 patients during SPT using either 2- or 4-handed dentistry in an operatory with either 0 or 20 additional air changes/h (ACH). Under clinical conditions, 20 additional ACH are adequate to eliminate aerosols produced during an SPT and before the cessation of the AGP. The presence of an assistant had no significant effect on the time needed for aerosol particles to return to baseline values following the AGP. This study supports the efficacy of 20 additional ACH during the process of AGP, but does not support the need for an extended fallow period or 4-handed dentistry to provide additional high-volume evacuation throughout the procedure.</p>","PeriodicalId":50005,"journal":{"name":"Journal of the Canadian Dental Association","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9977165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, fluoridation monitoring in Canada has historically been fragmented, and recent national estimates give little indication of trends at the provincial or municipal levels. We aimed to quantify fluoridation exposure trends in Alberta from 1950 to 2018 at both the population and municipal levels. Insights have implications for dental public health surveillance.</p><p><strong>Methods: </strong>Drawing from various public sources, we compiled a list of all Alberta municipalities, noting type of municipality and annual population count from 1950 to 2018. We recorded fluoridation status (excluding naturally occurring fluoride) by year for each municipality, based on the start and end (if ever) dates. We calculated annual fluoridation exposure at the population level (% of Alberta population exposed) and the municipality level (number of municipalities exposed) to visually assess trends over time.</p><p><strong>Results: </strong>Population exposure to fluoridation in Alberta generally increased from 1950 to 2010. A sharp drop occurred in 2011, after which exposure fluctuated at around 43-45%.

The high prevalence of hypertension coupled with its lack of initial clinical symptoms can make managing a hypertensive patient in a dental setting difficult. The dentist's role in managing hypertensive patients encompasses more than simple treatment modifications. Because of the frequency of dental checkups, dentists play an integral role in the detection of elevated blood pressure and appropriate subsequent referral. As such, it is imperative that dentists are aware of risk factors associated with hypertension to council patients early. In addition, antihypertensive medications pose a risk in dental treatment. Such drugs may produce various oral presentations and interact negatively with drugs commonly prescribed by the dentist. It is critical to recognize these changes and avoid possible interactions. Furthermore, dental treatment can often induce fear and anxiety resulting in an increase in blood pressure; this can further complicate management of patients with pre-existing hypertension. As research and recommendations are constantly changing, dentists must stay informed on how to appropriately administer care. This article is intended to provide the dental team with clear guidelines on the overall management of a hypertensive patient in a dental clinic.</p>","PeriodicalId":50005,"journal":{"name":"Journal of the Canadian Dental Association","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9383901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
