Given the importance of sterilizing human teeth before using them in research, the effects of a 25 kGy dose of gamma radiation on the mechanical properties of enamel and its resistance to demineralization were evaluated. Thirty human teeth were sectioned longitudinally, and while one half of each tooth was irradiated, the other half was kept as a control. Abraded and unabraded enamel slabs were...

Dental caries is a common chronic disease affecting humans in all age groups. Various factors can affect the formation of including demineralization and remineralization processes with oral flora; dietary hygiene habits; salivary composition, flow rate, pH buffering capacity; morphological features teeth; fluoride exposures, environmental socioeconomic factors. One most important causing inter-...

This study was conducted to evaluate the effect of fluoride varnishes containing different calcium phosphate sources on demineralization of initial primary enamel lesions. Forty-eight sound primary incisors were completely coated with nail varnish except for two 1x1 mm windows before being placed in demineralizing solution for 4 days. After demineralization, one of the windows in each tooth was...

Background: Development of white spot lesions (WSLs) around orthodontic brackets compromises esthetics and necessitates additional dental treatments. Objectives: This study aimed to assess the efficacy fluoride mouthwash combined with Er:YAG laser irradiation for prevention WSLs brackets. Methods: Orthodontic were bonded 50 bovine incisors. The entire tooth surface was coated acid-resistant var...

Minimal intervention is a key phrase in today's dental practice. Minimal intervention dentistry (MID) focuses on the least invasive treatment options possible in order to minimize tissue loss and patient discomfort. Concentrating mainly on prevention and early intervention of caries, MID's first basic principle is the remineralization of early carious lesions, advocating a biological or therape...

Periodontal disease is one of the most frequent conditions in individuals, having major health and social implications. Progressing as a chronic inflammation at the level of tooth support tissues, untreated chronic periodontitis may lead to a premature loss of the dental organ. Even though the main lesions caused by the periodontal disease affect the alveolo-dental ligaments, we tried to highli...

Sweeteners are divided by their sources into natural and synthetic and by their nutritional values into nutritive and non-nutritive. Xylitol is a five carbon natural sweetener found in fibrous vegetables and fruit, which offers many health benefits to human. On oral health xylitol prevents dental caries, retards demineralization of tooth enamel, promotes remineralization of tooth enamel, increa...

The Institute of Medicine, the Healthy People 2020 initiative, and the U.S. Surgeon General agree that oral health directly affects overall health.1-3 Fluoride is an important aspect of good oral care. It is inexpensive, easy to deliver, and effective. With 181 million Americans not visiting the dentist annually,4 family physicians have an essential role in oral health care. Fluoride is used in...

BACKGROUND The incorporation of fluoride into sealants has been viewed as a viable way to prevent pit-and-fissure caries by potential inhibition of demineralization through the release of fluoride to enamel. The authors conducted a study to examine the effect of a recently introduced fluoride-releasing sealant (ProSeal, Reliance Orthodontic Products, Itasca, Ill.) on enamel demineralization in ...
