Effects of phosphates in acid-containing beverages on tooth erosion.

Rat studies demonstrated that low-pH powdered beverage mixes containing monocalcium phosphate caused less molar erosion than reconstituted frozen orange juice and grape juice when these beverages were consumed at excessive levels. A number of sodium phosphate supplements in low-pH beverages were not as effective as monocalcium phosphate in preventing molar erosion. Total acidity or pH values of the beverages could not be used with reliability to predict their potential to cause molar erosion.

Status report on acid etching procedures. Council on Dental Materials and Devices.

The introduction of acid etching techniques into many dental disciplines has resulted in safe, simple, conservative, and sometimes more economic methods of treatment. Further, in some instances, it has extended greater opportunities for treating such groups as those physically and emotionally handicapped in whom preventive and restorative procedures are often difficult. It is a significant departure from conventional, established techniques and may supersede some and may share with other established techniques an adjunctive relationship. By many, acid etching techniques are viewed with cautious optimism. It is deceptively simple. Strict adherence to the basic principles of application is important to its success.

[Condition of the oral cavity in workers of Siarkopol in Gdańsk].

The purpose of the study was to investigate the clinical state of the mucosa of the oral cavity, the paradontium and dentition in workers of Siarkopol in Gdańsk. Stomatologic examinations were performed in 105 workers who had been exposed to the action of sulphur dust. The subjects examined, showed inflammatory changes in the mucosa of the oral cavity (72,4%) and nontypical erosion of tooth enamel (11,4%). 74,28% of the subjects examined showed changes in the paradontium. The oral cavity of all Siarkopol workers was found to be in a poor state of hygiene.

Cervical enamel: a danger zone.

The British Standards Institutions's document (1974) recommending toothpaste specifications states that 'There is no evidence that any toothpaste ever produces a level of abrasion causing harm to dental enamel'. This paper questions the assumption that the enamel crown, especially at the cervical margin, is able to cope with modern dietary insult and a 'good' oral hygiene regimen, regardless of the enamel abrasivity of the dentifrice used. Once the enamel crown is breached the underlying dentine is sensitive and vulnerable to physical damage. In this work the potential rates of erosive and abrasive loss are related to the thickness of the protective enamel and to the relevance of fluoride treatments for adults. It is suggested that improvements in dental care and an increased tooth life expectancy now make the loss of tooth tissues at the cervical margin more important than is apparent at first sight.

Saliva and salivary pellicle composition and proteomic profile in smokers vs. non-smokers and its effect on dental erosion.

OBJECTIVE: To analyse the salivary composition and proteomic profile of saliva and the salivary pellicle in smokers compared to non-smokers, and to examine potential differences in the erosion-protective capacity of the salivary pellicle. METHODS: Twenty-five smokers and 25 non-smokers were included. Unstimulated and stimulated saliva samples were analysed regarding flow rate, pH, buffer capacity, calcium, phosphate, fluoride, and protein content. Saliva and salivary pellicle samples were analysed by data-independent acquisition mass spectrometry (DIA-MS) for proteome profiling. In an in situ experiment, intraoral splints were loaded with bovine enamel and dentine specimens for 120 min. Pellicle-covered specimens were extraorally eroded (HCl, pH 2.3, 60 s). Calcium release was determined photometrically and compared to pellicle-free controls. RESULTS: Except for phosphate in stimulated saliva (padj.=0.003), salivary parameters were not significantly different between smokers and non-smokers. Proteome profiling detected 1759±154 proteins (cumulative 1963) in saliva, and 4262±362 proteins (cumulative 4625) in the salivary pellicle. The relative abundances of 282 (unstimulated saliva), 338 (stimulated saliva), and 4 (salivary pellicle) protein groups differed significantly between smokers and non-smokers. Functional enrichment analysis of differentially abundant human proteins revealed biological processes such as coagulation, immune response, and carcinogenic reactive oxygen species processes to be impacted by smoking. The salivary pellicle had a significant erosion-protective effect in enamel compared to the control (41.4 ± 6.3 nmol/mm2), but no differences between smokers (33.2 ± 10.6 nmol/mm2, padj.=0.001) and non-smokers (32.7 ± 8.6 nmol/mm2, padj.=0.001) were found. CONCLUSION: The proteomic profiles of both unstimulated and stimulated saliva and the salivary pellicle differ between smokers and non-smokers. CLINICAL SIGNIFICANCE: Despite the different proteomic profiles indicating a significant impact of smoking on the oral cavity, the erosion-protective capacity of the salivary pellicle of smokers and non-smokers does not differ.
