[1354 freshmen's dental investigation]

1354 freshmen have been investigated to discover the relationship between dental diseases and environments,living habits and personal sanitary conditions,because urban young men like sweet foods and snacks,the incidence of caries is greater in the cities than in the country,more people with tetracycline discolored tooth live in urban areas than in the rustic ones,which is due to dense living conditions, vulnerable to respiratory organs disease,medical conditions and convenience of taking tetracycline when ill;on the other hand,gingivitis is more common within the country students than within the city students,for those students from the country are used to brush their tooth after adolescence and usually have more dental calculus which is harmful to the gingiva.More than half of the investigated freshmen are ignorant of correct method of brushing and oral health and that is important factors of high rate of dental disease,according to the above reasons,the effective measures should educated to prevent dental disease.

Restoring tetracycline-stained teeth with a conservative preparation for porcelain veneers: case presentation.

Tetracycline exposure in utero and in early childhood often results in intrinsic tooth staining that varies in severity based upon timing, duration, and form of tetracycline administered. Traditionally, dental aesthetics compromised by tetracycline staining have been restored with modalities requiring aggressive tooth preparation. In this case involving a patient with extremely severe staining of healthy and aesthetically shaped dentition, a conservative tooth preparation strategy and porcelain veneers were utilized to preserve tooth shape and arch form while restoring natural color.

Green pigmentation of deciduous teeth: report of two cases.

The purpose of this paper was to present 2 cases of green pigmentation in primary teeth caused by hyperbilirubinemia, from different pathologies during the neonatal period. Medical history revealed systemic problems during the neonatal period of an infectious, neurological, renal, respiratory, and cardiological nature, as well as a high amount of bilirubin in both cases and hepatitis in the first. The staining in the teeth was due to hyperbilirubinemia, caused by these systemic conditions. The clinical characteristics of teeth may help in the diagnosis of present current or past systemic diseases. The reported cases confirm the relevance of past medical history in establishing the diagnosis of the etiology of green pigmentation as a result of high levels of bilirubin serum.

Longevity of composite restorations of traumatically injured teeth.

PURPOSE: To evaluate clinically the long-term (7-year) behavior of resin-based composite restorations and original fragment reattachments. METHODS: From an initial number of 130 young subjects (8-18 years old), only 60 fulfilled the inclusion criteria and consented to the evaluation of long-term follow-up of their restorations. Out of a total of 90 injured teeth, 70 were treated with direct composite restorations, and 20 with the original fragment reattachment technique. These 90 teeth were divided according to traditional (Andreasen, Ellis) classifications and according to a new classification (Spinas-Piroddi). Then the restorations were examined according to a modified version of USPHS method during the 7-year follow-up. RESULTS: Three-year old composite restorations needed some kind of treatment (ranging from polishing to the replacement of the restoration); in the period between 3-5 years, all the restorations (belonging to all of the injury types) needed a complete replacement. The results indicated that a restoration can probably be replaced three or four times before the tooth shows severe reduction of its adhesive properties. Composites cannot be used for long-term restorations; if the subject has completed his growth, the mandatory therapeutic alternatives are prosthetic restorations (crowns, porcelain veneers).

Dentists' and parents' perceptions of health, esthetics, and treatment of maxillary primary incisors.

PURPOSE: Dentists' and parents' assessment of primary maxillary incisors regarding attractiveness, perceived health, and treatment preferences were investigated in this study. METHODS: Sample groups of 103 general dentists, 67 pediatric dentists, 97 parents of children in low-income families and 112 parents of children in high-income families completed questionnaires presenting color photographs and radiographs of maxillary incisors. Questions addressed treatment need, health beliefs, and demographics. RESULTS: All groups recognized grossly carious teeth and carious teeth with visible sinus tracts as unhealthy and unattractive. All agreed that grossly carious teeth warranted extraction (dentists = 92%, parents = 73%). For carious teeth with sinus tracts, dentists favored extraction and restorations while parents favored fluoride application. Dentists rated a dark incisor as healthy and not requiring treatment. Parents rated a dark incisor as neutral for attractiveness and health, but favored extraction or restoration. All groups found anterior steel crowns esthetically unacceptable. Trust of the dentist, pain for the child, and dentist skill was important for parents in treatment plan acceptance. CONCLUSIONS: A dentist's inexperience in pediatrics may result in a failure to diagnose or recognize the significance of some conditions. Proper parental education can better inform parents on dental conditions requiring prompt professional attention. Although parents today are more involved in clinical decision-making, they still rely on the dentist's expertise and advice.

Clinical considerations for densely sintered alumina and zirconia restorations: Part 1.

Densely sintered alumina- and zirconia-based restorations were introduced to dentistry in the early 1990s and became a popular treatment modality, especially in situations requiring complete-coverage restorations. The use of industrial technologies for the fabrication of the restoration, simple clinical management, and pleasing esthetic outcome have made these restorations an attractive treatment alternative. This article reviews the nature of the materials used and the technologies involved and provides indications for clinical case selection and tooth preparation.

Patterns of tooth surface loss among winemakers.

There are a few documented case studies on the adverse effect of wine on both dental hard and soft tissues. Professional wine tasting could present some degree of increased risk to dental erosion. Alcoholic beverages with a low pH may cause erosion, particularly if the attack is of long duration, and repeated over time. The purpose of this study was to compare the prevalence and severity of tooth surface loss between winemakers (exposed) and their spouses (non-exposed). Utilising a cross-sectional, comparative study design, a clinical examination was conducted to assess caries status; the presence and severity of tooth surface loss; staining (presence or absence); fluorosis and prosthetic status. The salivary flow rate, buffering capacity and pH were also measured. Thirty-six persons, twenty-one winemakers and fifteen of their spouses participated in the study. It was possible to show that there was a difference in terms of the prevalence and severity of tooth surface loss between the teeth of winemakers and those who are not winemakers. The occurrence of tooth surface loss amongst winemakers was highly likely due to frequent exposure of their teeth to wine. Frequent exposure of the teeth to wine, as occurs among wine tasters, is deleterious to enamel, and constitutes an occupational hazard. Erosion is an occupational risk for wine tasters.

The effect of different fluoridation methods on the red wine staining potential on intensively bleached enamel in vitro.

PURPOSE: To study the effect in vitro of different fluoridation methods after intensive bleaching on the color of enamel slabs during a severe staining challenge with red wine. METHODS: 75 specimens were equally divided among five groups. Group 1 (no bleaching, no wine) served as control. Groups 2, 3 and 4 underwent bleaching with 35 % H2O2 for 10 minutes followed by home-bleaching for 8 hours/day with 10% carbamide peroxide on 14 consecutive days. Groups 2 and 3 were fluoridated for 1 hour with either Elmex gelée or Duraphat, respectively whereas Group 4 remained without fluoridation. Group 5 (no bleaching, no fluoride, wine) served as control for the influence of red wine on the color of untreated enamel. Color determination was accomplished using the CIE-Lab System. RESULTS: Nine successive cycles of wine saliva treatment (10 minutes wine, 23 hours 50 minutes saliva) for Groups 2-5 revealed the highest changes of a-values (deltaa= 4.17) (towards red) for the Duraphat-treated group (bleaching, Duraphat, wine) with significantly higher deltaa-values compared with Group 4 (bleaching, no fluoride, wine) (deltaa= 2.97). After final cleaning no differences were found between the three bleached groups (Groups 2, 3 and 4) for deltaL, deltaa, deltab and deltaE, respectively. Exposure to red wine led to an increase in a-values (deltaa= 0.44) of the intrinsic tooth color in Group 5 (no bleaching, no fluoride, wine) that was significantly different from baseline.

A novel dentifrice technology for advanced oral health protection: A review of technical and clinical data.

Throughout the world, dentifrices have played a key role in the practice of good oral hygiene and promotion of better oral health. In addition to providing general dental cleaning, toothpastes also have served as an excellent vehicle for the introduction of new agents that deliver therapeutic and cosmetic benefits. Key examples of using dentifrices to provide added benefits include the introduction in 1955 of the first fluoridated toothpaste clinically proven to fight caries (Crest Cavity Protection) and the launch of the first tartar-control dentifrice (Crest Tartar Control) in the mid-1980s. To continue expanding the health and esthetic benefits offered by a single dentifrice, a multitude of agents have been investigated over the past 3 decades. The focus of these investigations has been in the multibenefit segment, the most widely used among US consumers.
