RESUMO

BACKGROUND: Juvenile spongiotic gingival hyperplasia (JSGH) is a benign proliferation of non-keratinised stratified squamous epithelium with evident spongiosis, exocytosis leukocytes and dilated vessels with varying numbers of inflammatory cells. Although uncertain, it has been suggested that the epithelial proliferation is probably related to trauma and local irritants. It emerges as a painless erythematous patch or papule with an irregular surface. CASE REPORTS: We present a series of eight cases and a literature review of the clinical presentation and treatment approaches for JSGH. This series includes four females and four males with a mean age of 11.6 years, all complaining of injury to the gums. All lesions were painless and not bleeding. One patient associated the lesion with the onset of trauma and another with a previous history of an eruption cyst. Periapical radiographs of the adjacent area did not show any alteration of bone or teeth. Based on these findings, the diagnostic hypotheses were a non-neoplastic proliferative process or a factitious injury. Incisional biopsy was performed and histopathologic diagnosis was conclusive for JSGH. Surgical excision was conducted in three cases, and the other five cases were supported by clinical observation and plaque control in order to prevent gingival recession defects. After a follow-up period of 11 months (mean), no recurrence was observed for surgically treated cases and mild improvement was achieved with periodontal treatment. CONCLUSION: This case series illustrates the importance of diagnosis and follow-up of patients with JSGH. A conservative approach consisting of basic periodontal support instead of surgical excision may be indicated because of the risk of aesthetic defects at the involved areas.

RESUMO

Objective: This study aims to investigate the effects of different antiseptic mouthwash on microbiota around the mini-screw applied to patients undergoing fixed orthodontic treatment. Materials and Methods: From patients who have been undergoing fixed orthodontic treatment and who have mini-screws in their mouth, a total of 38 patients were selected for the study consisting of 4 groups, each of which has 15 mini-screws. The patients were selected from the following groups: no use of mouthwash (Group 1), use of 0.12% chlorhexidine gluconate-containing mouthwash (Group 2), use of essential oils-containing mouthwash (Group 3), and use of 7.5% povidone-iodine-containing mouthwash (Group 4). Plaque indices and gingival indices of the patients were measured at the beginning (T0) and at their appointments 3 weeks later (T1). In addition, biological samples were collected from the sulcus around the mini-screw with the help of sterile paper point. Results: The total number of microorganisms around the mini-screw in Group 2, Group 3, and Group 4 decreased significantly compared to Group 1. A significant decrease in Streptococcus oralis, Streptococcus mitis, Candida parapsilosis, total bacteria, plaque index, and gingival index count was observed in T1compared to T0. Conclusion: Antiseptic mouthwash in Group 2, Group 3, and Group 4 can be used to reduce the number of microbial microbiota around the mini-screw and to improve oral hygiene.

RESUMO

OBJECTIVE: To investigate the effect of two methods of propolis administration on plaque accumulation and microbial count as well as patient acceptance of each vehicle. STUDY DESIGN: A randomized clinical trial with two parallel arms was used with a sample of 60 high caries risk children 6-8 years old. Children were divided randomly into two groups. Group I: Children who received propolis chewing gum and instructed to chew it twice daily for at least twenty minutes, for two weeks. Group II: children who received propolis mouthwash and instructed to rinse twice daily for one minute. A plaque index was recorded and a plaque sample was collected from all participants at base line and after two weeks of treatment. All participants were asked to rate the preparation they received during treatment period on a Visual Analogue Scale chart. RESULTS: Data showed that propolis had a significant effect on reducing plaque scores and colony counts in both vehicles. There was no significant difference between both vehicles neither on plaque reduction nor on microbial count. However children preferred the gum formula. CONCLUSION: Propolis in both vehicles reduced plaque accumulation and microbial count which recommends its use as an antimicrobial agent in different vehicles.

RESUMO

PURPOSE: Candida albicans is frequently detected together with Streptococcus mutans in the plaque or biofilms of children with early childhood caries (ECC). The aim of this study was to examine the association of the microbial counts of C. albicans and S. mutans in the supragingival plaque with the activity status of carious lesions and oral health practices in children with ECC. MATERIALS AND METHODS: 66 children aged 5 years were examined and their caries status recorded as per the ICDAS-II and the Lesion Activity Assessment (LAA) criteria. A questionnaire covering oral health practices was administered to parents. Plaque samples were collected and cultured on mitis salivarus bacitracin (MSB) agar and CHROMagar. Data was analysed using Spearman's rank correlation and Mann-Whitney U test. RESULTS: There was a statistically significant positive correlation between the levels of S. mutans and C. albicans (rs = 0.702, p <0.001). A positive correlation was seen between the percentage of active carious lesions with the colony counts of S. mutans (rs = 0.884, p <0.001) and C. albicans (rs = 0.785, p <0.001). Improper toothbrushing practices, dietary and feeding practices were statistically significantly associated with activity of caries lesions, S. mutans and C. albicans count. CONCLUSION: The total count of C. albicans and S. mutans in the supragingival dental plaque of children with ECC increases with an increase in the percentage of active carious lesions and the severity of dental caries. Improper oral health practices can lead to increased number of active carious lesions, as well as increased microbial load of both S. mutans and C. albicans.

RESUMO

BACKGROUND: Dental biofilm accumulation and poor personal oral hygiene are known major risk factors for gingivitis and halitosis. However, it is not clear how studies compare the effectiveness of hygiene regimens, associated with outcomes centered on patients. METHODS: A randomized, blind, controlled clinical trial involving 58 participants aged from 12 to 17 years, who search the Department of Pediatric Dentistry of Universidade Metropolitana de Santos, will be conducted. Immediately, the volunteers will be inserted into Group 1 (commercially available hygiene regimen) or Group 2 (tooth brushing alone). In Group 1, participants will receive Colgate Total 12 toothpastes, Plax mouthwashes and Colgate Ultrasoft toothbrushes, while Group 2 will use Colgate Cavity Protection toothpastes and Colgate Ultrasoft toothbrushes. The interventions will be conducted in the periods of 1, 3, and 6 months after the baseline, when the evaluations will also be performed. Biofilm and halitosis indexes will be evaluated. Data regarding discomfort, satisfaction and the socioeconomic/individual characteristics will also be computed. DISCUSSION: Although toothbrushing has shown positive effects in decreasing biofilm and in gingival health, there is no comparison in the literature of different brushing regimens with halitosis measurement in adolescents. In addition, the effectiveness of these protocols would be confirmed from the acceptability of the volunteers.

RESUMO

Studies on interdental cleaning have shown an advantage of interdental brushes (IDB) over other interdental care products. Sticks (STK) made of rubber are often recommended as an alternative, as they are considered user-friendly, gentle but nevertheless effective. This laboratory study aimed to compare the cleaning efficiency with the same application force between IDB and STK. Brushes with different geometries and diameters were tested. Two conical STK from two manufacturers of the sizes "XS/S" (0.7-2.6 mm) and "L" (0.9-3.4 mm) were tested. For the IDB, one conical (2.7-3.4 mm), two cylindrical (1.9 and 2.5 mm) and one waisted brush (4-2-4 mm) were assessed. A geometric model with parallel-walled metal blocks (black and coated with titanium oxide) was used. The brushes were tested with one and five cleaning cycles each in horizontal direction. The test surfaces were measured planimetrically for cleaning efficiency by calculating the areas freed from titanium oxide in relation to the maximum cleanable total area. The maximum cleaning efficiency of the IDB was 45% at 1 mm distance with one cleaning cycle and 95% with five cycles. For the sticks, the cleaning efficiency with one cleaning cycle was 30% and 67% with five cycles. At a distance of 2 mm, the maximum cleaning efficiency was 50% with one cleaning cycle and 87% with five cycles for the IDBs and only 10% for the STKs. Taking into account the limitations of this study, the IDBs showed an overall better cleaning efficiency with the same application force, compared to STKs, with the waisted IDB achieving better cleaning efficiency than the conical IDB. In conclusion, STKs can be used in narrow interdental spaces where app opriate, but overall IDBs are more preferable in narrow and wider contact point conditions.

RESUMO

Objective: To investigate of effects of using phase-contrast video technique on education in oral hygiene training. This one blind, parallel randomized controlled trial was conducted in a tertiary clinic. Fifty-three patients who presented to the orthodontics department aged 12-20 years were divided into two groups randomly by computer-generated assigned codes to receive oral hygiene education. The participants were blinded to type of education method. Before orthodontic therapy, the control group was trained only by the conventional method, while the test group was trained by phase-contrast video microscopy method in addition to conventional method. Some images and videos of moving microorganisms in dental plaque were shown to the patients in test group on a computer monitor. Subjects and Methods: The bacterial count, plaque index, and gingival index scores were compared. Measurements were obtained in baseline and follow-ups which were repeated with 1-month intervals after the training. Results: The plaque index scores (1.05 ± 0.1 vs. 1.43 ± 0.2; P < 0.001) and gingival index scores (0.90 ± 0.1 vs. 1.14 ± 0.2; P < 0.001) in test group was statistically lower than those in control group at the end of the study. The gingival index scores reduced by 39% in test group vs. 14% in control group. The number of bacteria significantly decreased in the group trained with phase-contrast video microscope technique (8,059,133 ± 3016 vs. 10,830,600 ± 4919; 0.018). Conclusions: The training with phase-contrast microscopy has a more positive effect than the traditional method in oral hygiene education.

RESUMO

Palatoradicular grooves are usually found on the palatal or lateral roots of maxillary central and lateral incisors. Since clinical identification of these grooves are inaccessible and arduous in routine oral hygiene practices and are susceptible alcoves for microorganism habituation and plaque accumulation, it may result in acute to severe periodontitis and, if untreated, periapical pathosis also. This paper discusses about a female patient who reported pus discharge in left upper lateral incisor. Based on history, clinical examination and IOPA (intra-oral periapical radiograph), a deep pocket of about 10-14 mm was noticed in the left upper lateral incisor. A timely investigation was made and was treated surgically with advanced modified procedures which include odontoplasty and restoration of the defect with Platelet Rich Fibrin. After follow up of 6 months, the patient reported no signs of disease progression, had good oral hygiene and the tooth remained to be vital.

RESUMO

PURPOSE: To compare the effectiveness in reducing plaque and gingivitis of a fluoride toothpaste with 20% baking soda and a fluoride toothpaste control. METHODS: 159 subjects, who met the entry criteria, participated in this single-center, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed after 4, 8, and 12 weeks use of the assigned test or control toothpaste. After 12 weeks, participants resumed 4 weeks of their customary oral hygiene after which they were re-evaluated using the same measures. RESULTS: Both toothpastes statistically significantly reduced MGI, GBI, and PI versus baseline at all-time points. Brushing with the 20% baking soda toothpaste statistically significantly reduced MGI, PI, and GBI compared to the control toothpaste at all time points. After 12 weeks, the reductions in MGI, PI, and GBI were 12.6%, 9.6%, and 44.2%, respectively. After the 4-week customary oral hygiene period, the benefits of the study period had begun to diminish, but statistically significant reductions in MGI and GBI for the test versus control were still evident. This 3-month clinical study shows that brushing with fluoride toothpaste containing 20% baking soda reduces dental plaque and concurrently reduces gingival inflammation and bleeding compared to toothpaste with fluoride alone. CLINICAL SIGNIFICANCE: Fluoride toothpaste with 20% baking soda has the potential to offer multiple oral health benefits when used as an adjunct to regular tooth brushing and, therefore, may be confidently recommended to patients.

RESUMO

PURPOSE: To compare the effectiveness in reducing plaque and gingivitis of two fluoride toothpastes containing baking soda (35% and 20%) with a fluoride toothpaste control. METHODS: 319 subjects, who met entry criteria, participated in this single-center, three-cell, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed at baseline, and after 6 weeks, 3 and 6 months. RESULTS: All three toothpastes significantly (P< 0.0001) reduced MGI, GBI, and PI versus baseline, and the two baking soda toothpastes significantly (P< 0.0001) reduced MGI, GBI, and PI compared to the fluoride control, at all three time points. After 6 months use, the 35% and 20% baking soda toothpastes had reduced MGI, GBI and PI by 15.0%, 46.9%, and 18.3%, and 9.4%, 25.9%, and 12.4%, respectively, compared to the control. In addition, the 35% baking soda toothpaste had reduced (P≤ 0.0005) MGI, GBI, and PI by 6.2%, 28.4%, and 6.8%, respectively, compared to the 20% baking soda toothpaste. This clinical study showed that brushing with fluoride toothpastes containing baking soda at 35% and 20% reduces plaque, gingival inflammation and bleeding more effectively than regular fluoride toothpaste. Further, it showed that 35% baking soda toothpaste was more effective in reducing these parameters than 20% baking soda toothpaste. CLINICAL SIGNIFICANCE: Fluoride toothpastes containing 20% or more baking soda can provide significant and meaningful gingival health benefits when used regularly as an adjunct to tooth brushing.

RESUMO

PURPOSE: Currently, there is no consensus on recommendations for manual toothbrushing techniques between dentists, oral health therapists and dental companies. The aim of this systematic review is to identify and assess the quality of evidence of the effectiveness of manual toothbrushing techniques in the existing literature. METHODS: A broad search was conducted on the electronic databases Medline via Ovid, PubMed and EBSCO Dentistry & Oral Sciences. Included studies examined manual toothbrushing technique efficiency. Articles were assessed utilising the Cochrane Collaboration's tool for assessing risk of bias. Thirteen studies met the inclusion criteria and were included in this review. These included five randomised controlled trials (RCT), seven experimental non-randomised control studies and one in vitro study. RESULTS: Of the 3190 articles identified, 40 were relevant to manual toothbrushing and 13 were included in the final review. Studies indicating statistically significantly superior plaque removal for a given technique were Bass (one), modified Bass (one), Charter's (two), Fones (two), scrub (two), roll (one), modified Stillman (one), toothpick method (one). Four studies exhibited no statistically significant difference in effectiveness of plaque removal. Unfortunately, considerable variation was found between studies, making a definitive conclusion impossible in terms of an ideal manual toothbrushing technique that would promote plaque removal and reduce gingivitis. CONCLUSION: There is still insufficient evidence for suggesting that one toothbrushing method is more effective than another in plaque removal and reduction of gingivitis. Excessive variability in many aspects of the design and methodology of the selected studies hinder conclusions on an ideal manual toothbrushing technique. Experimental randomised controlled trials that follow the CONSORT guidelines are required to provide adequate-quality evidence and make any definitive conclusions on the relative effectiveness of manual toothbrushing techniques.

RESUMO

AIMS: The purpose of the present study was to compare the effect of a new mouth wash formulation consisting of chlorhexidine and chitosan on dental plaque and its reduction to that of chlorhexidine or chitosan alone. MATERIALS AND METHODS: This study was a single-blind randomized clinical trial with a parallel group design of 3 months duration. Patients (20-40 years) who fulfilled the inclusion and exclusion criteria were assigned equally to group 1: chlorhexidine (0.2%), group 2: chitosan (0.5%) or group 3: chlorhexidine - chitosan combination group. The clinical parameters were recorded at baseline, 6weeks and at 3months. All patients received thorough oral prophylaxis and were instructed to rinse with 10ml of mouthwash twice daily for 1 minute. RESULTS: The combination of chitosan and chlorhexidine showed a statistically significant reduction (p less than0.05) in plaque indices from baseline at all time intervals when compared to that of chlorhexidine or chitosan alone. CONCLUSIONS: Our study demonstrates that by unifying the properties of chitosan and chlorhexidine may result in a superior antiplaque effect than that of chlorhexidine alone.

RESUMO

AIMS: The purpose of this study was to evaluate the impact of fullfixed orthodontic appliances on the periodontium in adult patients. METHODS: Seventeen periodontally and systemically healthy subjects were selected from the Periodontal Clinic of Guarulhos University, 7 males and 10 females (mean age: 38.3 ± 6.3 years). The patients undergoing orthodontic treatment were submitted a clinical examination, a cone beam computed tomography at baseline and after 12 months of treatment. Subgingival biofilm samples were analyzed by Checkerboard DNA-DNA hybridization. Statistical analysis was performed by a Wilcoxon test. RESULTS: The percentage of sites with visible plaque increased (p =0.003), but no significant reduction in marginal bone was observed. The mean periodontal pocket depth was reduced (p=0.001) and the clinical attachment level significantly improved (p =0.001). There was a significant reduction in the mean proportions of the Actinomyces sp and an increase in the orange complex species. The proportions of the red complex species remained unchanged. CONCLUSIONS: In spite of increase in plaque accumulation no significant clinical or tomographic iatrogenic changes in periodontally healthy adults undergoing orthodontic full-fixed appliance treatment could be detected. The microbiological changes did not affect the periodontal parameters in monitored adult patients that received short period of orthodontic treatment.

RESUMO

OBJECTIVE: The objective of this systematic review and meta-analysis was to compare powered and manual toothbrushes for oral hygiene maintenance in orthodontic patients. METHODS: Electronic databases, including MEDLINE, Scopus, Google scholar, PubMed, Web of Science, the Cochrane Oral Health Group's Trials Register, and CENTRAL, were searched without language restrictions. Randomized clinical trials directly comparing manual and powered toothbrushing including patients with fixed orthodontic appliances reporting predefined outcomes with a follow-up period of at least 4 weeks were included. Using predefined data extraction forms, 2 authors independently undertook data extraction with conflict resolution by the third author. Quality assessment was based on the Cochrane Risk of Bias tool, and overall evidence base was assessed using the Grading of Recommendations Assessment, Development and Evaluation system. A random effects meta-analysis combined the treatment effects across studies. RESULTS: Five trials were considered appropriate for inclusion in the meta-analysis with 8 trials excluded. There are slight differences in plaque index reduction of 0.05 (-0.04, 0.13) and 0.11 (-0.10, 0.33) at 4 week and 8 week follow up, respectively, favoring manual toothbrushing, but this was not statistically significant. There are slight differences in gingival index reduction of -0.02 (-0.06, 0.02) and -0.01 (-0.05, 0.02) at 4 week and 8 week follow up, respectively, favoring powered brushing, but again, this was not statistically significant. The overall quality of evidence was very low to moderate for the primary outcomes. CONCLUSIONS: Using manual or powered tooth brushing with fixed orthodontic appliances does not reduce plaque or gingival indexes at 4 weeks and 8 weeks. This conclusion is, however, based on low quality of evidence from few studies. Greater standardization of the methodology used is desirable in future trials to increase our confidence in these findings.

RESUMO

The aim of this study was to evaluate changes in periodontal status and maxillary buccal bone by considering clinical and tomographic parameters during the first year of orthodontic expansion with Invisalign® aligners. Upper first (1PM) and upper second (2PM) premolars of 19 patients with orthodontic expansion requirement treated with Invisalign® aligners were evaluated. Plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and cone beam tomographic (CBCT) records were collected at 76 sites before starting treatment (T0) and at 12 months (T1). Bone height was measured from cementoenamel junction (CEJ) to the crest cortical bone (CC). Bone thickness was measured at two levels: 4 mm (CEJ+4) and 6 mm (CEJ+6) apical to the CEJ. A descriptive analysis was made of the variations of bone thickness and height in a series of cases. The average expansion was 1.93 mm for 1PM and 167 mm for 2PM. Arithmetic mean of distance CEJ-CC in 1PM was 3.05 mm at T0, and remained at 3.05 mm at T1. Arithmetic mean of distance CEJ-CC in 2PM was 2.06 mm at T0 and 2.31 at T1. Post-expansion, most of the analyzed sites (86%) exhibited a bone thickness of ≥0.5 mm. The greatest variations between T0 and T1 were observed at the level of 1PM CEJ+ 4 and 2PM CEJ+ 6. The minimal changes in the clinical records (GI, PI, PPD and CAL) between T0 and T1 were compatible with the maintenance of gingivalperiodontal health. Invisalign® for expansion movements did not produce substantial changes in the evaluated periodontal clinical parameters or in the bone measurements. Removable appliances reduce plaque retentive factors and favor adequate oral hygiene.

RESUMO

Purpose: The purpose of this study was to determine the relative plaque reduction efficacy of powered versus manual toothbrushes in children. Methods: A systematic review and meta-analysis were conducted based on a literature search that included Medline, Embase, FDA publications, Cochrane Database of Systematic Reviews, Dentistry and Oral Science, and Berman Medical Library, Hebrew University. Studies were chosen that were randomized controlled trials and published between 1980 to 2019 in English that compared plaque reduction with manual and powered toothbrushes in children. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence. Results: From a search of 1,502 articles, nine articles were selected for meta-analysis. A statistically significant plaque reduction benefit for a powered toothbrush versus manual toothbrush (P<0.001): combined mean difference (MD) was 0.590 and the 95 percent confidence interval was 0.352 to 0.828 (random-effects model). Two tests revealed considerable heterogeneity (I² equals 96 percent; Cochran's Q, P<0.001). A low possibility of bias was indicated by Begg-Mazumdar and Egger tests (P>0.1 for both). Evidence quality was given a GRADE score of moderate. Conclusions: Powered toothbrushes were more effective than manual toothbrushes for plaque removal in children.

RESUMO

It is well established that dental plaque on teeth leads to gingivitis and periodontitis, and that several mechanical and chemical methods of plaque control can prevent gingivitis. The aim of the current review is to summarize and synthesize the available scientific evidence supporting practices for mechanical oral hygiene to prevent periodontal diseases. Evidence for contemporary practices of mechanical oral hygiene to prevent periodontal disease relies on studies of gingivitis patients. General recommendations concerning the ideal oral hygiene devices and procedures are still inconclusive. However, toothbrushing and interdental cleaning remain the mainstays of prevention of periodontal diseases. The primary approach requires individually tailored instruction for implementation of a systematic oral hygiene regimen.

RESUMO

There is increasing public interest in natural or herbal-based healthcare products. This trend is not only visible in supermarkets and dental practices, but also in the scientific world. An improving number of clinical trials are being conducted to validate the claims made about these products in regards to periodontal health. Among single component preparations, Aloe vera and green tea are the most studied natural ingredients. Concerning polyherbal mixtures, triphala has garnered great interest. The effects of these natural products on periodontal health is encouraging, with almost all studies showing an inhibitory effect on plaque accumulation and an improvement in gingival health. However, more studies are needed to be able to design clinical guidelines to guide the use of these natural products in periodontal practice. For most of these products, few studies are available and, moreover, the available studies are limited in duration, the number of participants, and the specific composition of the natural product is often not described in detail.

RESUMO

Purpose: The purpose of this study was to evaluate the effects of using mobile text messages and a novel floss holder as compared to finger flossing or the novel floss holder alone, on the psychological, behavioral, and clinical parameters of patients with gingivitis.Methods: A total 165 adults were assessed for eligibility and 144 met the criteria for randomization into three groups: Finger Floss (FF, n=43), Novel Floss Holder (NFH, n= 40), and Novel Floss Holder plus Text Messages (NFH+TM, n= 61) following a dental hygiene consultation appointment. Gingival bleeding points were measured on probing (BOMP) at baseline and four months later by a calibrated dental hygienist, blinded to the experimental groups. Participants also self-reported their oral hygiene behaviors, and indicated psychological determinants of behavior change prior to the dental hygiene consultation and at four months. Descriptive statistics and repeated measures analysis of variance (ANOVA) were used to compare groups over time.Results: Two subjects dropped out of the study making the total number of participants 142. At the four month follow-up, the NFH group and the NFH+TM groups demonstrated significantly higher levels of self-reported flossing, action self-efficacy, intention, action planning, and action control. The NFH+TM group showed lower levels of bleeding and higher levels of oral hygiene and recovery self-efficacy than the other groups, in addition to higher levels of maintenance self-efficacy as compared to the FF group.Conclusions: The use of a novel floss holder, NFH, was shown to improve the behavioral and psychological determinants of periodontal health four months after introduction of the device. However the clinical measures of BOMP only improved significantly when used in conjunction with text messages (NFH+TM). The use of a consciousness awareness technique,TMs, in combination with a novel device, may help patients to reach therapeutic objectives and contribute to the management of periodontal pathologies such as gingivitis.

RESUMO

Background and Aims: Although Streptococcus mutans has been implicated as the major etiologic agent in the development of dental caries, however, this organism has not been found to be present in all children with caries. Thus it remains to be elucidated whether a single or specific consortium of bacteria is responsible for the caries process. The aim of this study is to evaluate the oral microflora of Indian children suffering from dental caries and to compare the same in children with no caries. Methods: The study was carried out on 67 out-patient 2-14 years old children who reported to the department of Paediatric Dentistry. Dental plaque samples from superficial and deep carious lesions and caries free surfaces in caries active children (n = 35) were collected using a sterile excavator in storage vials and subjected to various conventional and molecular microbial techniques. Caries free children (n = 32), who did not have any carious lesion served as controls. The data obtained was subjected to Pearson's Chi Square/Fischer's Exact tests to determine the statistical difference between the microflora of groups. Results: Main organisms isolated were: Streptococcal species mainly S anginosus, S salivarius, S gordonii: Lactobacilli spp; Coagulase negative Staphylococci, Staph epidermidis, Staph aureus. Other organisms such as Klebsiella spp, Acinetobacter, Enterococcus, E coli could also be found. There was a statistical difference in the frequency of isolation of non-mutans Streptococcal species (P = 0.008) and Lactobacilli species (P = 0.0001) in the two groups. Conclusions: The study suggests that caries activity in this population of children is associated with a diverse microbial flora without detectable S mutans. Main organisms associated with dental caries in this population are: Gram-positive cocci and bacilli mainly the non-mutans Streptococcus and Lactobacilli. Frequent consumption of sugar containing food promotes the presence and growth of cariogenic organisms.
