Knowledge of undergraduate and postgraduate dental students about managing traumatic dental injuries based on the 2020 International Association of Dental Traumatology guidelines: A online survey of 10 dental schools from 10 countries.

BACKGROUND/AIM: The knowledge of dental students about managing traumatic dental injuries (TDIs) may not be uniform, depending on global location and dental education. The aim of this study was to evaluate the level of knowledge of undergraduate and postgraduate students specializing in endodontics and pediatric dentistry at 10 dental schools in 10 countries about the 2020 International Association of Dental Traumatology (IADT) guidelines regarding the management of TDIs. MATERIALS & METHODS: A previously published questionnaire was used in the current survey. It was an online survey with 12 questions regarding the management of TDIs and some additional questions regarding sociodemographic and professional profiles of the participants were added. The survey was distributed to final-year undergraduate students and postgraduate students in pediatric dentistry and endodontics from 10 dental schools. Simple frequency distributions and descriptive statistics were predominantly used to describe the data. Differences in the median percentage scores among the student categories were assessed using the Kruskal-Wallis test followed by Dwass-Steel-Critchlow-Fligner pairwise comparisons. RESULTS: A total of 347 undergraduates, 126 postgraduates in endodontics, and 72 postgraduates in pediatric dentistry from 10 dental schools participated in this survey. The postgraduates had a significantly higher percentage score for correct responses compared with the undergraduates. No significant difference was observed between the endodontic and pediatric dentistry postgraduates. CONCLUSION: The knowledge possessed by undergraduate and postgraduate students concerning the IADT-recommended management of TDIs varied across the globe and some aspects were found to be deficient. This study emphasizes the critical importance of reassessing the teaching and learning activities pertaining to the management of TDIs.

Minor physical anomalies including palatal rugae pattern and palatal dimensions in children with sickle cell disease: A cross-sectional analytical study.

Background: Sickle cell disease (SCD) is the most common hereditary hemoglobinopathy, which delays growth leading to an altered skeleton and craniofacial pattern. Palatal rugae patterning has been considered the regulator of the development of the palate. The purpose of the research work was to study the morphology of the palate, rugae pattern, and its dimensions in SCD children and compare them with healthy normal children, and to evaluate its role as minor physical anomalies (MPAs). Methods: A cross-sectional case-control study was designed as per STROBE guidelines. The sample comprised 50 children diagnosed with sickle cell disease (Group SCD) and 50 normal healthy children as control (Group C) belonging to the same age group (10-18 years). Dental impressions were made, followed by the pouring of dental casts. The length of the palatal rugae was measured and categorized into primary (>5 mm), secondary (3 mm-5 mm), and fragmentary rugae (<3 mm). The shape of each primary palatal rugae was identified and categorized as curved, wavy, straight, circular and non-specific. Linear and angular measurements of the palatal rugae patterns and palatal dimensions (width, height, area) were measured and recorded. Results: The total number of palatal rugae and fragmentary rugae was lesser in Group SCD than in Group C (p < 0.05). The depth of the palate was significantly increased, whereas the area of the palate significantly decreased in Group SCD. Conclusions: The children with SCD showed distinctive palatal rugae patterns and dimensions when compared with normal healthy children that can be attributed as potential MPAs for sickle cell disease. Children with SCD had an under-developed palatal rugae pattern with a deep, narrow and small palate when compared to healthy children.The dimensions of the palatal rugae pattern in SCD showed reduced distance between the incisive papilla and the first and last rugae, indicating a further decrease in the anteroposterior dimensions of the palate. These findings may aid in the early diagnosis and prevention of malocclusion in children with SCD by appropriate interceptive orthodontic treatment.

Antimicrobial Properties and Substantivity of Gentamicin, Amoxicillin and Metronidazole (GAM) Antibiotic Solution with Chitosan as a Root Canal Irrigant - A Preliminary Study.

Irrigation is one of the steps that is very crucial in a high-quality endodontic treatment. Hence, irrigant with good substantivity is essential which must not only be effective for the dissolution of the organic tissues but also effectively eliminate bacterial contamination. The aim of the study was to investigate and compare the antimicrobial efficacy of gentamicin, amoxicillin, and metronidazole (GAM) antibiotic solution, chitosan and their combination (GAMC), and analyze their sustained release property. Mueller-Hinton agar medium was inoculated with E. faecalis. The medicaments were then poured at the center of the plate in the prepared wells and incubated at 37°C. Antibacterial property of each medicament was evaluated by measuring the diameter of the zone of inhibition at the end of 48 hours. The substantivity of GAM antibiotic solution and the GAMC was checked using an ultraviolet spectrophotometer. The GAMC demonstrated the strongest antimicrobial activity and good sustained-release properties. Distilled water showed no activity, and chlorhexidine acted as the positive control. Conclusion: The combination of gentamicin, amoxicillin, and metronidazole (GAM) solution with chitosan (GAMC) can be used as an alternative intracanal irrigant as it was found to be a potent antibacterial agent.

Reporting Quality of the Abstracts for Randomized Controlled Trials in Pediatric Dentistry.

OBJECTIVES: The purpose of this study is to systematically appraise the reporting quality of abstracts for randomized controlled trials (RCT) published in pediatric dentistry using Consolidated Standards of Reporting Trials (CONSORT) for abstracts and to analyze the relationship between the characteristics of the RCT to the quality of abstracts. MATERIALS AND METHODS: RCTs published in Pediatric Dentistry were retrieved from the PubMed database from 2016 to 2021. The quality of abstracts was appraised using CONSORT for abstracts checklist by two independent reviewers. STATISTICAL ANALYSIS: In descriptive statistics, frequency and percentage analysis were used for categorical variables, whereas mean and standard deviation were used for continuous variables. To find the significant difference between the bivariate samples in independent groups, Mann-Whitney U test was employed. Multivariate analysis was performed using Kruskal-Wallis test and Mann-Whitney U tests. Probability value of p-value less than 0.05 was considered as statistically significant. RESULTS: Two hundred abstracts were included in the study. All the abstracts adequately reported the "objective" item, whereas only 2 and 4% of abstracts adequately addressed "randomization" and "harms" items, respectively. A significant relationship was observed between the continent of first author/corresponding author, number of authors, impact factor, adherence to CONSORT guidelines, word count, focus of study, and a priori protocol registration to the quality of abstracts (p < 0.05). CONCLUSION: The abstracts of the RCT included in the study did not adequately follow the CONSORT for abstract guidelines. Adherence to the reporting guidelines would improve the overall reporting quality of abstracts of RCT published in Pediatric Dentistry. The overall mean score of the abstracts was 6.80 out of 15 indicating that the abstracts did not adequately follow the CONSORT for abstract reporting guidelines.

Antibacterial and Antibiofilm Efficacy of Copper-Doped Phosphate Glass on Pathogenic Bacteria.

This study aimed to investigate the antibacterial [minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC)] and antibiofilm activity [log10 colony forming unit/mL (CFU/mL) and biofilm disruption] of copper-doped phosphate glass (CDPG) against Streptococcus oralis, Enterococcus faecalis, Lactobacillus casei, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. METHODS: the antibacterial activity was determined using microbroth dilution and time-kill assay. The antibiofilm activity was investigated using crystal violet and confocal laser scanning microscopy. Bacteria growing in absence of CDPG were used as controls. RESULTS: the MIC was ≥125 mg of CPDG/mL; the log10 CFU/mL reduction ranged from 2.66-3.14 to 6.23-9.65 after 4 and 24 h respectively. Generally, no growth was observed after 24 h of treatment with CDPG; the MBC was 250 mg/mL for L. casei and S. oralis while 500 mg/mL for the rest of the bacteria. The highest and lowest antibiofilm activity was observed against S. oralis and E. coli respectively. Three patterns of complete biofilm disruption were seen: (i) large areas with E. fecalis and S. oralis, (ii) medium-size pockets with S. aureus and P. aeruginosa, or (iii) small areas with E. coli and L. casei. CONCLUSION: CDPG can be potentially used as an antibacterial and an antibiofilm agent against oral biofilm-forming bacteria.

Clinical efficacy of green tea, aloe vera and chlorhexidine mouthwashes in the treatment of dental biofilm induced gingivitis: A multi-arm, double-blinded, randomized controlled clinical trial.

OBJECTIVE: This multi-arm, randomized, double-blinded, controlled clinical trial was designed to evaluate the clinical efficacy of 0.5% green tea (GT), 0.2% chlorhexidine (CHX) and aloe vera (AV) mouthwash as compared to the control (CNT) group (scaling and polishing alone with no mouthwash) in the management of dental biofilm induced gingivitis among 18-40-year-old patients. MATERIAL AND METHODS: Sixty patients with generalized dental biofilm-induced gingivitis were randomly allocated to four study groups (n = 15 each) for treatment, namely Group GT, Group CHX, Group AV and Group CNT after scaling and polishing were administered to all the patients. Plaque index (PI), gingival index (GI) and sulcular bleeding index (SBI) were recorded at baseline, 14th and 21st day. RESULTS: PI, GI and SBI at various time intervals (baseline, 14th and 21st day) showed high statistically significant differences within the group (p < 0.01). Among these, the maximum percentage change was found in the CHX group followed by GT when evaluated from baseline to 21st day. The least percentage change was found in the AV group for PI and GI while the CNT group showed the least percentage change for sulcular index when evaluated from 14th to 21st day. Inter-group results showed high statistically significant differences (p < 0.01) for PI and GI when evaluated between baseline to 14th day and baseline to 21st day. SBI also showed statistically significant differences (p < 0.05) when evaluated between baselines to 14th day and baseline to 21st day. CONCLUSION: Green tea mouthwash displayed a significant reduction in plaque index, gingival index and sulcular bleeding index. 0.5% green tea catechin has equivalent anti-plaque efficacy as 0.2% chlorhexidine gluconate and can be considered a potent alternative to prevent and treat gingival diseases.

Parents' and Children's Acceptance of Silver Diamine Fluoride Application on Primary Teeth in the United Arab Emirates.

PURPOSE: To assess the acceptance of silver diamine fluoride (SDF) application on children's teeth among parents and children in the United Arab Emirates (UAE). MATERIALS AND METHODS: A pre-tested questionnaire and clinical photographs of SDF-treated teeth were employed to determine preferences among 370 parents for its use in managing dental caries in their children's teeth. A similar number of children ages 4 to 8 years were also interviewed, and their reaction to SDF was assessed through a facial image scale after showing pictures of pre- and post-SDF treated primary teeth. RESULTS: 265 mothers and 105 fathers participated in this study. The Χ2 test was used to test for the statistically significant differences between parental perceptions. Almost all parents responded that SDF was either unacceptable or extremely unacceptable for their children's anterior teeth in comparison to 63% for posterior teeth (p = 0.009). Fathers were more comfortable with SDF treatment for posterior teeth on a scale of 3.1 out of 4, in comparison to 1.8 for mothers (p = 0.007). Parents with limited education (up to primary school) showed greater SDF acceptance in comparison to college-graduate parents (p = 0.000). The level of parental SDF acceptance increased with the children's behavioural barriers. The older children had a lower acceptance rate, at 1.2 and 2.5 for anterior and posterior teeth, respectively (p = 0.000). CONCLUSIONS: SDF was acceptable to UAE-based parents for posterior teeth; however, they preferred it for anterior teeth only when advanced behavioural management (e.g., sedation) was advocated. Socioeconomic factors moderated their SDF preference regarding the location of tooth and treatment difficulty. Younger children were relatively more receptive to SDF use than were older children.

Comparison of clinical outcomes of non-surgical adjunctive use of the 980-nm diode laser to conventional periodontal flap procedure-a randomised controlled split-mouth clinical trial.

Lasers have been found to be effective as an adjunctive in periodontal therapy. The objective of the study was to compare the outcomes of non-surgical adjunctive use of 980-nm diode laser to that of conventional flap surgery in terms of clinical outcome measures and radiographic osseous defect depths. This study was designed as a double-blinded split-mouth randomised controlled clinical trial. A total of fifteen patients (30 quadrants) with generalised periodontitis stage III grade B were randomly assigned test group (diode laser) and control group (conventional flap surgery). Both test and control groups had 15 quadrants each. At 3 months, the probing pocket depth (PPD) was 3.46 ± 0.19 mm (test) and 4.20 ± 0.20 mm (control), with a statistically significant difference between the groups (p = 0.01). Similarly, at 6 months re-evaluation, PPD was 1.46 ± 0.12 mm (test) and 2.33 ± 0.13 mm (control) with a highly significant statistical difference (p = 0.001). Plaque index showed a difference between both test and control groups at baseline, 3 months and 6 months (p = 0.001) while gingival index, modified sulcular bleeding index and radiographic osseous defect depth showed a difference at 3 months and 6 months (p = 0.001). Within the study's limitations, 980-nm diode laser can result in significant improvements in the clinical and radiographic parameters and is very well tolerated by the subjects.

Comparison of Time-kill Assay to Evaluate the Antimicrobial Efficacy of Garlic (Allium sativum) and Guava (Psidium guajava) Extracts on Periodontal Pathogens.

BACKGROUND: The role of Gram-negative anaerobic periodontal pathogens in periodontal diseases has led to the loss of tooth-supporting structures. These diseases can be prevented by the inhibition of bacterial biofilm on the tooth surfaces. Many treatment modalities have been tried to prevent periodontal diseases. With the rise in resistance to synthetic antimicrobials, there is a requirement to develop natural antimicrobials for the control of periodontitis. AIM: The aim of the study was to evaluate and compare the efficacy of garlic (Allium sativum) and guava (Psidium guajava) extracts on Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans using time-kill assay. MATERIALS AND METHODS: Aqueous garlic extract (AGaE), ethanolic garlic extract (EGaE), aqueous guava extract (AGuE), and ethanolic guava extract (EGuE) were prepared. Time-kill assays were performed on P. gingivalis and A. actinomycetemcomitans. The aqueous and ethanolic extracts of guava and garlic were compared to assess the maximum bactericidal potency. RESULTS: The comparison of time-kill assay of AGaE and AGuE on P. gingivalis showed a statistically significant difference at 2 h (t = 5.29, P < 0.01), 4 h (t = -4.867, P < 0.01), and 6 h (t = -3.647, P < 0.001). The comparison of time-kill assay of EGaE and EGuE on A. actinomycetemcomitans showed a statistically significant difference at 2 h (t = 4.54, P < 0.01) and highly significant difference at 4 h (t = 6.57, P < 0.001). CONCLUSIONS: The, judicious use of these phytomedicinal products could be cost-effective and also the adverse effects caused due to the long-term usage of synthetic antimicrobials can be avoided.

Efficacy of Psidium guajava and Allium sativum Extracts as Antimicrobial Agents against Periodontal Pathogens.

BACKGROUND: The accumulation and maturation of bacterial plaque at the gingival margin is widely recognized as the primary etiological factor in the development of chronic periodontitis. With the rise in bacterial resistance to antibiotics, there is considerable interest in the development of other classes of antimicrobials for the control of infection. AIM: The aim of this study was to evaluate the efficacy of Psidium guajava (guava) and Allium sativum (garlic) on Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. MATERIALS AND METHODS: Aqueous guava extract (AGvE), ethanolic guava extract (EGvE), aqueous garlic extract (AGE), and ethanolic garlic extract (EGE) were prepared. The inhibitory effects of these extracts for the periodontal pathogens were tested by agar well diffusion method. Minimal inhibitory concentration (MIC) of the aqueous and ethanol extracts of guava and garlic was determined by macrobroth dilution method. Minimum bactericidal concentration (MBC) was done to observe the bactericidal effect of the guava and garlic extracts against the organisms. RESULTS: Of the AGE, 25, 50, and 75 µL showed 16, 20, and 25 mm zone of inhibition, respectively, on P. gingivalis. The AGE showed greater bacteriostatic activity against the P. gingivalis with MIC determined at 16.6 µL/mL. MIC determined for AGvE and EGvE was at 75 µL/mL concentration for P. gingivalis, whereas EGvE showed the activity at 75 µL/mL on P. gingivalis. MIC determined for AGvE was at 50 µL/mL, whereas MIC determined for EGvE was at 3.12 µL/mL for A. actinomycetemcomitans. CONCLUSION: P. guajava and A. sativum displayed a significant antibacterial effect. A. sativum was found to be most effective against P. gingivalis, whereas P. guajava showed the highest efficacy on A. actinomycetemcomitans.

RMS-MP3 Classification: A Newly Proposed Digital MP3 Classification in Assessing Skeletal Maturity.

BACKGROUND: Growth is a crucial inconsistent parameter, which is a primary requisite in diagnosing and planning orthodontic and orthopedic treatment. The use of the epiphyseal development of the middle phalanx of the third finger (MP3) radiograph is advisable instead of hand and wrist radiographs for growth assessment. AIM: (1) To propose a simple, precise, and reliable classification system of MP3 staging-RMS MP3 classification and (2) to check the reliability of newly proposed RMS-MP3 classification in assessing the skeletal maturity. MATERIALS AND METHODS: Standardized MP3 digital radiographs of 276 children between 5 years and 13 years of age were included in the study. The epiphysis and diaphysis were measured, and the percentage of epiphysis formed when compared to diaphysis was obtained using our formula. A new classification was designed and proposed. The assessment of the MP3 developmental stages was carried out by all the four investigators (two pedodontists and two nonpedodontists) according to the older classification by Liete et al. and the newly proposed RMS-MP3 classification. RESULTS: Among nonpedodontists, there was 51% perfect agreement of maturity stages according to old classification and 90% perfect agreement according to newly proposed classification. Among pedodontists, there was 90% perfect agreement of maturity stages according to old classification and 99% perfect agreement according to the newly proposed classification. An estimated 89% of agreement was seen in RMS-MP3 classification among all the four observers when compared to 38% of agreement in the old classification. CONCLUSION: The newly proposed RMS-MP3 classification can be an alternative and perfect aid in assessing growth with accuracy, precision, ease, and an increased reliability.

Effectiveness of Distraction Techniques in Managing Pediatric Dental Patients.

AIM: Children having dental anxiety usually hesitate to seek dental care which can result in poor oral health and may lead to expensive and complex dental treatment in the future. The aim of the present study is to compare and evaluate the effectiveness of various distraction techniques in managing pediatric dental patients. MATERIALS AND METHODS: Eighty healthy children selected for the study were randomly divided into 4 groups with 20 children in each group. Group I was termed as the control group; in group II, the audio distraction technique was used. Group III received audio-video distraction (AVD) by means of a chair-mounted audio-video device and group IV received AVD by means of a ceiling-mounted television. Each child had four dental visits. Child's anxiety in each visit was assessed using four parameters: RMS pictorial scale (RMS-PS), Venham picture test (VPT), pulse rate, and oxygen saturation. RESULTS: Ceiling-mounted AVD was found to be the most effective in reducing the anxiety followed by chair-mounted AVD. Audio distraction was found to be the least effective but was better than the control group. CONCLUSION: The AVD technique is simple, passive, and noninvasive means of behavior management and can be used alternatively in managing anxious pediatric dental patients.

AIM: The aim of this review was to analyze the data in the available literature regarding aspects of periodontally accelerated orthodontic therapy such as reduction in treatment time, variation in surgical techniques, and patient satisfaction. MATERIALS AND METHODS: An internet-based search was performed for the articles published between January 2008 and August 2018 using keywords periodontal accelerated orthodontic tooth movement, corticotomy, bone grafting, tooth movement, and treatment duration. A total of 84 articles were obtained from MEDLINE and Embase search engines, of which 31 articles were eligible to be included for the systematic review. RESULTS: On analysis, it was observed that the earlier studies were predominantly pertaining to case reports. In the later part of the decade considered in this review, it was observed that the emphasis was given to clinical and animal studies. CONCLUSIONS: Most of the studies included in the review concluded that there was a significant reduction in orthodontic treatment duration using periodontal accelerated techniques compared to conventional orthodontic treatment.

A Newly Proposed Regression Equation for Mixed Dentition Analysis Using the Sum of the Width of Permanent Mandibular Central Incisors and Permanent Mandibular First Molars as a Predictor of Width of Unerupted Canine and Premolars

Objective: To determine linear regression equation to predict the mesiodistal widths of the permanent canines and premolars based on the sum of the widths of the two permanent mandibular first molars and two mandibular central incisors. Material and Methods: The sample consisted of 800 (400 males and 400 females) permanent dentition casts of Chhattisgarh population. Mesiodistal crown widths of teeth were measured with digital caliper. The correlation and linear regression equations between the calculated four teeth (two permanent mandibular first molars and two central incisors) and the canine-premolars segments of both the arches were developed. Results: No significant differences were found in right and left side of the arch. Sexual dimorphism was significant in teeth sizes with higher mesiodistal dimension in males. A good correlation values varying from 0.51 to 0.67 was found. New standardized regression equations were formulated for the prediction of the mesiodistal widths of unerupted canines and premolars for Chhattisgarh population. Conclusion: Calculating mesiodistal widths of unerupted canine and premolars with help of two permanent mandibular molars and two mandibular central incisors, which erupt early in the oral cavity, can be an alternative and best predictor for the mixed dentition analysis.

Evaluation of the Efficacy of Guava Extract as an Antimicrobial Agent on Periodontal Pathogens.

AIM: The present study was undertaken to assess the inhibitory effect of guava extracts on Porphyromonas gingivalis and Aggregatibacteractinomycetemcomitans, to assess the time-kill curve of P. gingivalis and A. actinomycetemcomitans, and to determine the antiproteolytic activity of guava on P. gingivalis. MATERIALS AND METHODS: Kanamycin blood agar was used to isolate P. gingivalis and A. actinomycetemcomitans. Ethanolic guava extract (EGE) and aqueous guava extract (AGE) were prepared and the inhibitory effects of these extracts for two periodontal pathogens were tested by minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) procedures. Antibacterial activity of guava extracts was determined by well diffusion method. Antiproteolytic activity of guava on protease of P. gingivalis was determined by gelatin liquefaction test. RESULTS: The MIC determined for AGE and EGE was at 75 µL/mL concentration for P. gingivalis, whereas EGE exhibited the activity at 75 µL/mL on P. gingivalis. The MIC determined for AGE was at 50 µL/mL for A. actinomycetemcomitans, whereas MIC determined for EGE was at 3.12 µL/mL for A. actinomycetemcomitans. Porphyromonas gingivalis was susceptible to EGE compared with AGE. Aggregatibacter actinomycetemcomitans was more susceptible to guava extracts compared with P. gingivalis. CONCLUSION: Guava extract may be a potential therapeutic agent for periodontitis as it shows significant activity against both P. gingivalis and A. actinomycetemcomitans. CLINICAL SIGNIFICANCE: Guava leaves extract can be used as economical and suitable adjuvant to synthetic drugs and can be a potential therapeutic agent for periodontitis.

RMS tactile scale: An innovative tactile anxiety scale for visually impaired children.

INTRODUCTION: Behavior guidance is considered to be the backbone of pediatric dentistry which differentiates us from the other fields in dental sciences. Anxiety and fear being the primary concern in pediatric patients, has to be taken into consideration for the visually impaired children too. In the present study, an innovative anxiety scale RMS tactile scale (RMS-TS) was designed for the visually impaired children. Introducing newer concept other than Braille in the dental clinic for such patients can help in coping up and bringing out positive behavior in the special children. AIMS AND OBJECTIVE: The study aimed to validate and assess the efficacy of RMS-TS for visually impaired child and compare it with modified dental anxiety scale (MDAS) and Braille scale. MATERIALS AND METHODS: A total of hundred children of age 12-15 years from the special school were selected for the study. MDAS, RMS-TS, and Braille scale were used to determine the pretreatment anxiety scores in the visually impaired children. RESULTS: The validity of the RMS-TS in the pretreatment anxiety in the assessment of child's dental anxiety is supported by its strong correlation with both the scales. CONCLUSIONS: The RMS-TS can be reliable anxiety assessment scale for measuring child's dental anxiety in visually impaired children. It can be used alone or in combination with other methods to improve assessment of dental anxiety.

Role of Intelligence Quotient (IQ) on anxiety and behavior in children with hearing and speech impairment.

AIM: To assess and compare the role of IQ on anxiety and behavior of children with and without hearing and speech impairment. MATERIAL AND METHODS: A total of 120 children of age group 7-14 years were included in the study, of which control group comprised of 60 normal healthy children and 60 hearing and speech impaired children formed the study group. The study was done in two consecutive sessions. First appointment for Culture Fair Intelligence Test and second appointment for RMS pictorial anxiety score (RMS-PS) and Frankl behavior rating which were assessed during oral prophylaxis. RESULTS: IQ of children with hearing and speech impairment was lower as compared to normal healthy children. There was a positive correlation between IQ and anxiety in children with hearing and speech impairment while no correlation was found with behavior. CONCLUSION: Children with hearing and speech impairment are less anxious and more cooperative compared to normal healthy child in the dental setting and are, therefore, easier to manage.

A New Regression Equation Proposed For Mixed Dentition Analysis in Chhattisgarh, Central India Population

Objective: To develop and propose a new regression for mixed dentition analysis in Chhattisgarh, Central India population. Material and Methods: The permanent dentition dental casts of 800 (400 males and 400 females) Chhattisgarh subjects were selected. Digital caliper was used to measure the mesiodistal crown widths of teeth. The linear regression equations and correlation between four mandibular incisors and the canine-premolars segments of maxillary and mandibular arches were developed (modified Tanaka-Johnston equation) and proposed for Chhattisgarh population. Results: New standardized regression equations were formulated to predict the mesiodistal widths of unerupted canines and premolars especially for Chhattisgarh, Central India population. The equation in males for maxillary arch was Y = 11.90 + 0.39 (X) and for mandibular arch was Y = 12.23 + 0.36 (X). Similarly, the equation in females for maxillary arch was Y = 14.40 + 0.26 (X) and for mandibular arch was Y= 10.26 + 0.43 (X). A significant sexual dimorphism in teeth sizes was seen with higher mesio distal dimension in males in Chhattisgarh population. Conclusion: Sum of the mesiodistal diameter of permanent mandibular incisors can be used reliably to predict/estimate the sum of mesiodistal diameters of unerupted canines and premolars with the new regression equations.

Three-Alarm System: Revisited to treat Thumb-sucking Habit.

Thumb and digit-sucking habits or non-nutritive sucking are considered to be the most prevalent among oral habits. Most children stop thumb sucking on their own. If the habit continues beyond 3 to 4 years of age, it not only affects the dental occlusion, but the shape of the thumb/digit may be altered as well. This article presents the management of thumb sucking by modified RURS, elbow guard incorporated with revised 'three-alarm' system.
