caries management research & clinical application
present dentistry It is a sad fact of life that every dentist is trained that if there is an area of decay in a tooth, the only way to treat this is to drill the decay out or amputate it, and then place a filling, which will need replacement at some time in the future; at worse, the tooth may have to be removed.

No 1306 Clinical Reversal of Occlusal Pit and Fissure Carious Lesions (OPFCLs) Holmes J 1 and Lynch E 2. 1 Adentec & UKSmiles, Wokingham, Berkshire, UK 2 Health and Healthcare Group, School of Dentistry, Queen s University Belfast, Northern Ireland Introduction Recent reports in the UK national press have lead to an interest by the general public in ozone technologies. This study, Clinical Reversal of Occlusal Pit and Fissure Carious Lesions (OPFCLs) using Ozone in General Dental Practice was set up to assess the effects of the use of ozone on occlusal pit and fissure caries in a general dental practice. Aim The aim of this study was to observe and measure the Clinical Reversal, Stabilisation or Progression of Clinical Reversal of Occlusal Pit and Fissure Carious Lesions (OPFCLs) using Ozone in a General Dental Practice. Materials and Methods The data sets were obtained from 237 patients with 978 occlusal pit and fissure carious lesions (OPFCLs), who presented to UKSmiles, a general dental practice, near London, over a period from December 2001 through to the end of August 2002, and subsequently attended a 2-month recall. Each tooth was randomized and assigned to two groups; a, be treated with O 3 or b, left as a control. All surfaces to be measured were cleaned with the ProphyFlex (KaVo) and each lesion assigned an index number using a Clinical Severity Index (CSI) as shown in Table 1b. This Index value was recorded. Various indices have been used in past studies, and a Clinical Severity Index (CSI, Table 1), developed by Professor Edward Lynch (Queens University, Belfast) & Dr Julian Holmes (UKSmiles, Wokingham) was used to determine how long each lesion was to be treated with ozone. This treatment time varied from 0 seconds for the lowest (0) CSI score to 40 seconds with the highest (5) CSI score. The CSI used in this study was based on the Ekstrand index for clinical caries detection. The Ekstrand Index was modified to allow easy and fast indexing of lesions in a general dental practice environment, so that once this pilot study is completed, other general dental practices could send in data for an extended study using reproducible criteria. Table 1; Clinical Severity Index Table 2; DV & CSI Data Table 3 & 4; Changes in the DV & CSI Data Results - Statistics The mean DIAGNOdent (DV) and CSI values are shown in Table 2. The mean DV in the O 3 group decreased compared to baseline measurements (p < 0.01) showing remineralisation. There was no statistical difference between start DV s and finish DV f in the control group. There were statistically significant differences in the changes in DIAGNOdent readings between the treated lesions after an average of 2 months, and between the O 3 group / control group at the 2-month review (p < 0.001). The table shows that the O 3 group averaged DV s reading of 65 at the start and at recall, the O 3 group had a DV f average of 16. The control group averaged DV s reading of 63 at the start of the study period & at recall this changed to 66. The majority of the control lesions showed little improvement or signs of remineralisation. Discussion The Clinical Severity Index above was the primary outcome variable. Three Ozone treated lesions showed increased DIAGNOdent values at the recall visit. These lesions consisted of exposed dentine which had become darker in colour. In these lesions, it is postulated that the remineralisation process has led to an increase in the stain or colouration of the lesions. The DIAGNOdent is very sensitive to stains, which is why the cleaning protocol prior to DIAGNOdent assessment is so important. The results acquired from this ozone study mirror those from other clinical research trials in other research centres. By increasing the O 3 Tx time up to 40 seconds, the remineralisation observed has become more predictable. Conclusions Over 99% of the ozone treated primary occlusal fissure carious lesions had clinically reversed based on the clinical severity index and the DIAGNOdent readings (P<0.001). The control primary occlusal fissure carious lesions, which had not received any ozone treatment, did not significantly change.

No 2752 Introduction There is a great deal of interest by the general public in ozone technologies, following press reports of this new treatment modality for tooth decay. This study, Clinical Reversal of Occlusal Carious Lesions (OCLs) using Ozone in General Dental Practice is based on a previous study, Clinical Reversal of Pit & Fissure Carious Lesions, published in 2002 by Holmes J et al, with extended data. Aim The aim of this study was to observe and measure the Clinical Reversal, Stabilisation or Progression of Occlusal Carious Lesions (OCLs) using Ozone in a General Dental Practice. Materials and Methods The data sets were obtained from 376 patients with 2364 occlusal carious lesions (OCLs), who presented to UKSmiles, a general dental practice, near London, over a period from July 2001 through to the end of December 2002. All these patients have been reviewed for a minimum of 6 months. The early patients have now been followed for 18 months.(table 1) Each tooth was randomized and assigned to two groups; a, be treated with O3 or b, left as a control. All surfaces to be measured were cleaned with the ProphyFlex (KaVo) and each lesion assigned an index number using a Clinical Severity Index (CSI) as shown in Table 2. This Index value was recorded. Various indices have been used in past studies, and a Clinical Severity Index (Table 2), developed by Holmes et al, 2002 was used to determine treatment time with o2one. This treatment time varied from 0 seconds for the lowest (0) CSI score to 40 seconds with the highest (5) CSI score. The CSI used in this study is based on the Ekstrand index.the CSI & DIAGNOdent (KaVo) allow easy and fast indexing of lesions in a general dental practice environment, so that other general dental practices can contribute data for an extended European study using reproducible criteria. Results Statistics The increased data sets have confirmed the earlier study results published in 2002, with no change in the results. The mean DIAGNOdent (DV) and CSI values are shown in Table 3. The mean DV in the O3 group decreased compared to baseline measurements (p < 0.01) showing remineralisation. There was no statistical difference between start DVs and finish DVf in the control group. There were statistically significant differences in the changes in DIAGNOdent readings between the treated lesions after an average of 2 months, and between the O3 group / control group at the 2-month review (p < 0.001). The table shows that the O3 group averaged DVs reading of 65 at the start and at recall, the O3 group had a DVf average of 16. The control group averaged DVs reading of 63 at the start of the study period & at recall this changed to 66. The majority of the control lesions showed little improvement or signs of remineralisation. Clinical Reversal of Occlusal Carious Lesions (OCLs) Holmes J. Health and Healthcare Group, School of Dentistry, Queen s University Belfast, Northern Ireland Results Statistics (ctd) The CSI scores are shown in Table 4. The majority of lesions reversed from CSI 4 to 0 in the ozone group, when compared to the control group (p < 0.001). The control group overall showed no improvement. At the first assessment, 90% of all lesions for O3 Tx fall into categories 3, 4 & 5, & 67% of all lesions for O3 Tx fall into CSI groups 5 & 4. After O3 treatment, the CSI data shows 93% of the O3 Tx lesions falling into CSI 0 & 1. There is a clear shift in the distribution of DVs, to DV f in Table 4, showing a clear trend towards remineralisation. 61% of all lesions were assessed with a DVs of >50, compared to a DVf at recall where 97% of all lesions had changed to a DVf of <30. This finding is supported by earlier studies where the treatment time was limited to 10 or 20 seconds (1,2). Discussion The Clinical Severity Index has continued to prove a valuable assessment tool, and is now used in dental practices which offer ozone treatment in the UK. Three Ozone treated lesions showed increased DIAGNOdent values at the recall visit. These lesions consisted of exposed dentine which had become darker in colour. In these lesions, it is postulated that the remineralisation process has led to an increase in the stain or colouration of the lesions. The DIAGNOdent is very sensitive to stains, which is why the cleaning protocol prior to DIAGNOdent assessment is so important. The results acquired from this ozone study mirror those from other clinical research trials in other research centres. By increasing the O3 Tx time up to 40 seconds, the re-mineralisation observed has become more predictable. Conclusions Over 99% of the ozone treated occlusal fissure carious lesions had clinically reversed based on the clinical severity index and the DIAGNOdent readings (P<0.001). The control primary occlusal fissure carious lesions, which had not received any ozone treatment, did not significantly change. Patients who are offered this treatment modality, as an alternative to conventional amputation therapy have embraced this new technology. Research by Domingo H (2002) has shown there is little anxiety and fear associated with this treatment method, and it has wide application in the treatment of patients of all ages. Treatment is pain free, fast, and patients are happy to pay for this treatment modality References Baysan A., Whiley RA., Lynch E.

Gerodontology 2003; 20: 106-114. ~ to assess the efficacy of an ozone delivery system combined with the daily use of a remineralising toothpaste, mouthrinse and spray for the management of non- cavitated leathery primary root carious lesions (PRCL s) in an ageing patient group (>60, mean 70.8yrs, SD+ 6).
research in dental care results: the detail ~ Progression 0 1 2 3 4 Hard Leathery Reversal Soft Holmes J showed that 3 months after ozone treatment (40 seconds) 69% of caries had reversed to hard from CSI 2. Re-treatment at 3, 6, 12 and 18 months, resulted in 100% of caries reversing to hard by the 18 month and 24 month reviews. It is difficult to hypothesise whether all caries would have reversed to hard without re-treatment, although Baysan et al showed that 81% of caries (CSI 1 or 2) had reversed to hard 3 months after a single 20-second ozone treatment.
Economic Savings Treating Root Caries with Ozone or Air Abrasion H. DOMINGO, J. HOLMES, L. ABU-NABA'A, H. AL SHORMAN, A. BAYSAN and R. FREEMAN Queen's University of Belfast, United Kingdom Introduction Ozone treatment has been shown to significantly arrests root carious lesions (1-4). However no direct time and cost comparison has been completed comparing Ozone treatment with conventional dental treatment methods. Aim To assess if a new technology in a dental practice (HealOzone 5, Fig.1) could reduce the treatment time and cost for treatment of primary root caries at the baseline treatment visit. Materials and Methods Ozone, produced by the HealOzone device was selected for a time comparison with either Air Abrasion (Fig.2 PrepStart, Danville, USA), and a glass ionomer filling material (Fig 3. FujiVII, GC Corp, Japan 6), or traditional drill and fill (D&F) procedures (using a conventional glass-ionomer cement) for the management of primary root caries (PRCL s) in an ageing patient group (>60, mean 70.8yrs, SD 7) in a general dental practice. A total of 68 subjects with 3 lesions each (204 PRCL s in total) were recruited. The lesions were randomly assigned into three groups; treatment with; 1.Ozone, or; 2. Air abrasion and filling (A&F), or; 3. Traditional drilling and filling (D&F). In groups 1 & 2 PRCL preparation was carried out without the need for local anaesthetics. All lesions were finished with hand instruments (excavators), before restoration with a glass ionomer filling material (FujiVII). This modified ART technique is the subject offurther research. Results and Discussion 64 subjects completed this study. There were no observed adverse events. The mean time required for ozone treatment was 40 seconds (SD 5 seconds) for each lesion. The mean time required for A&F 9 minutes (540 seconds (SD 90 seconds). The mean time required for D&F was 27 minutes (1620 seconds (SD 8 minutes)) (overall p < 0.01). Ozone treatment was faster than traditional D&F by a factor of 40 and faster than A&F by 21. Air abrasion decreased the mean time for cavity preparation by 4 times when compared to traditional rotary drills (67 seconds (SD 12) compared to 4.5 minutes (SD 1.75 minutes) (p < 0.05)). The cost* of the treatment was assessed. The average cost to treat a lesion with ozone was 6.90, with A&F, 13.90; and with D+F 31.10. The potential NHS fee was assessed as 44.00. The gross potential profit for Ozone T x 37.10, for AA 30.10 and D&F 13.50 *Assumes 3 lesions treated at same appointment, surgery costs of 60.00/hour & UK NHS Fee Scale (Schedule of Fees June 2003) Products Used Fig.1 The HealOzone device CurOzone Inc USA & KaVo GmbH Germany Fig.2 The PrepStart Danville Engineering USA Fig.3 FujiVII GC Corp Japan Conclusion The combination of modern technologies, such as air abrasion, with Ozone offer economic savings for dental practices and patients. Compared with conventional drilling and filling of root caries, Ozone treatment offers potential cost savings in the treatment of caries. References 1. Lynch E, Baysan A, Silwood C, Grootveld M.

research in dental care Does ozone damage dental nerve / pulp tissue? Chou J, Boyd D, Tompkins G. Effect of Ozone Treatment on Interleukin Levels in Dental Pulp IADR Abstract 0036, 2005 Objective: To determine whether therapeutic levels of ozone stimulate production of the inflammatory cytokines interleukin-2 (IL-2) and interleukin-6 (IL-6) in healthy teeth. Conclusion: From the experiment, there was no evidence that ozone treatment stimulated an increase in the levels of IL-6 and IL-2 in healthy dental pulp. This suggests that ozone elicits negligible inflammatory responses (if not reduces levels of inflammation) when applied to healthy teeth, and may have potential for prophylactic treatment of patients with high caries risk.
