TI - Biocompatibility of resin-modified filling materials. SO - Critical Reviews in Oral Biology & Medicine Vol 11(3) (pp 333-355), 2000. AB - Increasing numbers of resin-based dental restorations have been placed over the past decade. During this same period, the public interest in the local and especially systemic adverse effects caused by dental materials has increased significantly. It has been found that each resin-based material releases several components into the oral environment. In particular, the comonomer, triethyleneglycol di-methacrylate (TEGDMA), and the 'hydrophilic' monomer, 2-hydroxy-ethyl-methacrylate (HEMA), are leached out from various composite resins and 'adhesive' materials (e.g., resin-modified glass-ionomer cements [GICs] and dentin adhesives) in considerable amounts during the first 24 hours after polymerization. Numerous unbound resin components may leach into saliva during the initial phase after polymerization, and later, due to degradation or erosion of the resinous restoration. Those substances may be systemically distributed and could potentially cause adverse systemic effects in patients. In addition, absorption of organic substances from unpolymerized material, through unprotected skin, due to manual contact may pose a special risk for dental personnel. This is borne out by the increasing numbers of dental nurses, technicians, and dentists who present with allergic reactions to one or more resin components, like HEMA, glutaraldehyde, ethyleneglycol di-methacrylate (EGDMA), and dibenzoyl peroxide (DPO). However, it must be emphasized that, except for conventional composite resins, data reported on the release of substances from resin-based materials are scarce. There is very little reliable information with respect to the biological interactions between resin components and various tissues. Those interactions may be either protective, like absorption to dentin, or detrimental, e.g., inflammatory reactions of soft tissues. Microbial effects have also been observed which may contribute indirectly to caries and irritation of the pulp. Therefore, it is critical, both for our patients and for the profession, that the biological effects of resin-based filling materials be clarified in the near future.

TI - A clinical evaluation of plaque accumulation and gingival reaction following bonding with fuji IX glass ionomer cement and right on composite resin. SO - Biomedicine Vol 19(1) (pp 79-83), 1999. AB - The gingival/periodontal health status of young patients undergoing orthodontic treatment has been the focus of attention by orthodontists and periodontists. It is widely believed that an important rationale for performing orthodontic treatment is to promote the health of the periodontium thereby enhancing longevity of the dentition. It is therefore assumed that adults with untreated malocclusion would be subject to o greater prevalence of periodontal disease than if their malocclusions had been corrected orthodontically. Although there is no scientific basis to support the concern that orthodontic tooth movement may initiate gingivitis or cause periodontal attachment loss. It is generally conceded that the greater plaque-retentive nature of orthodontic appliances aids in the plaque accumulation at the gingival margin and thus may contribute to the incidence of severity of gingival inflammation. The ongoing monitoring of gingival and periodontal health by orthodontists through out the treatment period and repeated reinforcement of acceptable oral hygiene routines have become an integral part of modern practice. Numerous clinical studies have demonstrated the beneficial effect of an oral hygiene programme carried out in conjunction with orthodontic treatment.

SO - Journal of Biomedical Materials Research Vol 45(3) (pp 192-197), 1999. AB - Although pit and fissure sealants have been utilized extensively in dentistry as a way of preventing occlusal caries, results described by Olea et al. (1996) raised concerns about the safety of sealants and other resin- based dental materials due to the reported presence of bisphenol A (BPA) and its dimethacrylate ester (BPA-DM). Although the release of these compounds from dental materials has not been substantiated by two subsequent studies, we believed it was important to confirm or refute the report that BPA and BPA-DM have estrogenic activity in vitro. We grew breast cancer cells (MCF- 7, T-47D, ZR-75-1) known to proliferate under estrogenic stimulation in phenol red-free DMEM containing human serum and concentrations of BPA or BPA- DM ranging from 10-8M to 5 x 10-6M. After 1 week, plates were harvested for crystal violet or sulforhodamine-B assays, and the optical densities of groups of treated cells were compared with values from control cells. At concentrations at or above 10-6M, both BPA and BPA-DM significantly increased cell proliferation (p < 0.05), comparable to the increase seen with 10-9M of estrogen. Flow cytometric methods demonstrated that these mitogenic effects occurred within 24 h of exposure to estrogen, BPA, or BPA- DM. The increase in DNA synthesis was analogous to that seen with estrogen stimulation. Thus, we confirmed that BPA and BPA-DM cause cell proliferation at micromolar concentrations that exceed the effective concentrations of estrogen by 1 to 10,000-fold.

TI - Barodontalgia: A review, and the influence of simulated diving on microleakage and on the retention of full cast crowns. SO - Military Medicine Vol 164(3) (pp 221-227), 1999. AB - This paper reviews the causes of barodontalgia and reports on a study that indicates a possible cause of barodontalgia in the diver. In the study, extracted teeth had full cast crowns cemented with either a zinc phosphate, a glass ionomer, or a resin cement, and simulated diving to 30 m (3.0 atmospheres) was performed. During simulated diving, the teeth were pressure cycled 15 times to 3 atmospheres and microleakage was monitored. The force required to dislodge the crown was then tested; a significant difference was found between the zinc phosphate and the glass ionomer cement groups (p < 0.01). No difference was found between the resin cement groups. Microleakage was also detected in the zinc phosphate and glass ionomer cement groups and was found to occur sooner, and to a greater extent with zinc phosphate. No microleakage was detected in the resin cement experimental group. This study showed that the retention of full cast crowns to extracted teeth is reduced after pressure cycling and that microleakage does occur if the crowns are cemented with either zinc phosphate cement or glass ionomer cement.

TI - A longitudinal study of schoolchildren's experience in the North Carolina dental Medicaid program, 1984 through 1992. SO - American Journal of Public Health Vol 88(11) (pp 1669-1673), 1998. AB - Objectives. This evaluation of a state Medicaid dental program describes dental treatment received, relates treatment needed to treatment received, and describes enrollment and use over an 8-year period. Methods. Three databases were linked: (1) clinical records from a 1986/87 statewide epidemiological survey, providing data on treatment need; (2) Medicaid dental claims from 1984 through 1992, providing data on treatment received; and (3) Medicaid enrollment flies from 1984 through 1992. Results. Half of Medicaid- enrolled children never used dental services. Among users of dental services, 45% and 25% of children needed restorations in primary and permanent teeth, respectively. In this group, 29% had all needs met, 28% had needs partially met, and 43% had no needs met. Forty-six percent of children sought care for only 1 year. Conclusions. Federal guidelines for dental care are not met in this typical Medicaid population of short-term enrollees who use services sporadically. Programs should aim to increase use and ensure that all needed services, especially preventive procedures such as sealants, can be completed within the short period of time a child attends for care.

SO - Journal of Clinical Laser Medicine & Surgery Vol 16(4) (pp 211-215), 1998. AB - Objective: The present in vivo study was performed to examine the long- term effects of combined CO2 laser treatment and fluoridation on hypersensitive dental necks. Summary Background Data: Attempts have been made to treat dental hypersensitivity by sealing exposed dentinal tubules, primarily using fluoride preparations, strontium chloride, and hydroxyapatite. However, these treatment methods have the disadvantage that the preparation is effective only for a limited period of time and must be applied repeatedly, at short intervals. The CO2 laser has been shown to have an excellent sealing effect on hypersensitive dentinal surfaces. Methods: Test subjects suffering from dentinal hypersensitivity were recruited from the patients of the Department of Conservative Dentistry, School of Dentistry of the University of Vienna, Austria and treated with combined laser irradiation and fluoridation with stannous fluoride gel. The patients were followed up for a period of 18 months. In vivo examinations were supplemented by atomic absorption spectroscopy (AAS) of tiny dentin samples obtained from the dental necks 6 weeks and 18 months after laser treatment and by scanning electron microscopy (SEM). Results: Compared to conventional fluoridation, combined laser irradiation and fluoridation was shown to be effective in the treatment of hypersensitive dental necks. When success was defined as complete freedom from pain, the success rate in the laser group was 96.5%. Furthermore, examinations of irradiated teeth under the scanning electron microscope still revealed complete closure of the dentinal tubules four and six months after laser treatment. AAS showed that tin was present in the samples, which indicates that combined laser treatment and fluoridation result in permanent integration of fluoride in the dentin surface. Conclusions: Based on these results, the CO2 laser can be recommended as an ideal tool for desensitization of dental necks.

SO - Military Medicine Vol 163(3) (pp 155-158), 1998. AB - This paper explores the need for and the prevalence of dental sealants in active duty U.S. military personnel. The data come from the 1994 Tri- Service Comprehensive Oral Health Survey. Data were collected on 13,050 Army, Air Force, Marine Corps, and Navy active duty personnel at 26 sites. Women and minorities were oversampled. Both bivariate and logistic regression analyses were done on the need for at least one dental sealant and the prevalence of at least one dental sealant in service members. Weighted data (1,669,662) were used for the bivariate analyses; unweighted data were used for the regressions. Results show that 3.6% of service members need dental sealants and that 6.8% have dental sealants. The need for dental sealants varies across age, rank, and branch of service. The prevalence of dental sealants varies across age, race, rank, and branch of service. The cost- effectiveness of dental sealants in this population should be established.

SO - Forensic Science International Vol 88(2) (pp 163-168), 1997. AB - We assessed the value of an alternative light source for detecting white composite dental materials in burned and unburned teeth. Teeth filled with 18 different restorative materials (composite, glass ionomer or hybrid composite), were viewed with a Polilight(TM). Between 415 nm and 555 nm, the glass ionomers showed distinctly different optical properties from the other materials: they either fluoresced or appeared darker. Wavelengths 415 nm to 530 nm gave a general enhancement in composite detection (17 of 18 materials). Light above 590 nm was of little value, enhancing detection in only 2 of 18 materials. After simulated burning of the teeth, there was enhanced visibility of 8 of 18 materials at wavelengths under 350 nm. Burning destroyed the previously distinct optical properties of the glass ionomers. Overall, this alternative light source aids the identification of white composite dental materials and could be used in routine forensic odontology practice.

TI - The advantage of CO2-treated dental necks, in comparison with a standard method: Results of an in vivo study. SO - Journal of Clinical Laser Medicine & Surgery Vol 14(1) (pp 27-32), 1996. AB - Various methods are used for treatment of hypersensitive dental necks. They all aim to seal exposed dentinal tubules, which are open toward the oral cavity and transmit stimuli to the sensitive nerve endings of the tooth pulp. The main sealing materials are fluoride preparations, strontium chloride, and hydroxyapatite. However, these materials must be applied periodically to achieve permanent freedom from pain. Since the introduction of laser technology into dentistry, efforts have been made to treat dentine hypersensitivity with the laser. An in vitro study revealed that CO2 laser irradiation results in almost complete closure of the dentinal tubules in the dental neck region. In the present in vivo study, the efficacy of laser treatment was examined in 72 patients with dentine hypersensitivity and 72 control patients over a period of 12 weeks. When success was defined as complete freedom from pain, the success rate in the laser group was 94.5%; when marked pain relief was included in the definition of treatment success, 98.6% of the patients were treated successfully. Treatment of the control group with conventional dental neck fluoridation resulted in no marked improvement. Laser Doppler measurements of pulpal blood flow immediately before and after treatment revealed no effects of laser irradiation on pulpal blood flow. Dentine samples were obtained from the dental necks 6 weeks after laser treatment and examined with atomic absorption spectroscopy (AAS). Tin was present in the samples, which suggests that the combined laser treatment and fluoridation result in permanent integration of fluoride in the dentine surface. <10> UI - 1995067224 AU - Akehurst R AU - Sanderson D IN - SCHARR, Management School, University of Sheffield, 9 Mappin Street,Sheffield S1 4DT; United Kingdom.

AB - Oral health currently represents an appreciable drain on NHS resources, accounting for 4% of total NHS expenditure each year, In order to effect an improvement in overall dental health, policies need to be targeted towards those most at risk of poor oral status. This paper explores a number of strategies available for preventing caries: - promoting improved self-administered oral hygiene - encouraging better use of the General Dental Service - reducing sugar consumption - fluoridation of water - making use of the community dental service - prophylactic fissure sealants. The evidence available on which to base decisions is less than perfect. However, the most effective and cost effective approach appears to be the fluoridation of water supplies. <11> UI - 1994125032 AU - Herrstrom P AU - Hogstedt B IN - Hertig Knut Health Centre, Bryggaregatan 1,S-302 43 Halmstad; Sweden. TI - Dental restorative materials and the prevalence of eczema, allergic rhino- conjunctivitis, and asthma in schoolchildren: Dental amalgam and allergy in schoolchildren. SO - Scandinavian Journal of Primary Health Care Vol 12(1) (pp 3-8), 1994. AB - Objective - To study the association between allergic diseases (eczema, allergic rhino-conjunctivitis, and asthma) and different types of dental restorative materials (amalgam, composite, and glass ionomer) in Swedish schoolchildren. Design - Cross-sectional survey with a questionnaire asking for symptoms of allergic disease during the previous year. This information was combined with current dental status (number and type of filled tooth surfaces). Setting - Primary care and a school in the centre of a middle- sized Swedish town (approx. 80,000 inhabitants). Participants - 348 pupils of both sexes 13 - 15 years old. Outcome measures - The occurrence of allergic disease in pupils with and without dental fillings of different types. The mean number and type of filled tooth surfaces in diseased and healthy pupils. Results - 44% of the pupils had no amalgam fillings. This group of children reported significantly more often asthmatic symptoms than the group with amalgam (P=0.02). The asthmatic children had a lower mean number of amalgam surfaces than the other pupils (P=0.002) and also a lower mean number of filled tooth surfaces of all types. Conclusion - The results of this study do not support the theory that amalgam fillings increase the prevalence of allergic diseases or allergic reactivity as such in schoolchildren. Neither do composite and glass ionomer seem to cause such complications. <12> UI - 1993091185 AU - Alhadainy HA AU - Himel VT IN - College of Dentistry, University of Tennessee, 875 Union Avenue,Memphis, TN 38103; United States.

Measurements of cuspal flexure using linear variable displacement transducers were carried out for 90 min after the placement of two types of reinforced glass ionomer cement. The measurements demonstrated that no movement occurred except in cases where the materials were allowed to dehydrate. Under these circumstances the opposing cusps moved toward one another. This movement was observed to be directly related to time. Microleakage was very much less than that observed for composite materials evaluated under the same test conditions. <14> UI - 1993022370 AU - Hansen EK IN - Helsingorsgade 7,DK-3400 Hillerod; Denmark.

The use of a poorly radiopaque material as a base under other restorative materials can mislead the dentist to a diagnosis of recurrent decay. This study investigates the radiopacity of these materials and proposes a minimal radiopacity under which a material should not be used as a base of liner. All base, liner, and core formulations of glass ionomer under investigation were more radiopaque than dentin. All restorative and luting formulations of glass ionomer under investigation were less radiopaque than dentin and therefore should be avoided as bases of liners. <19> UI - 1990168595 AU - Forss H AU - Seppa L IN - Faculty of Dentistry, University of Kuopio, POB 6, SF 70211 Kuopio; Finland.
