Malocclusion among patients at Agartala, Tripura, India.

Malocclusion is the mal-relationship of dental arches with or without an irregularity of the teeth. Therefore, it is of interest to estimate the rate of occurrence of malocclusion within the population of Agartala city, Tripura, India. The study included 850 individuals ranging from 16 to 24 years of age, which were categorized into five distinct classifications, namely normal occlusion, Angle's Class I malocclusion, Class II Division 1, Class II Division 2, and Class III malocclusion. Data shows that normal occlusal alignment was observed in 29.41% of the participants, whereas a majority of 70.59% exhibited various forms of malocclusion among this population.

Effect of different cavity liners on nanocomposite resin shear bond strength to dentine.

The effect of different cavity liners on the shear bond strength of nanocomposite to dentin is of interest. A total of sixty extracted caries-free maxillary, mandibular molars were randomly assigned to four groups in the following manner Group 1: control (no cavity liner), group 2: Biodentin, group 3: Apacal ART and Group 4: Giomer. Following the application of different cavity liners based on the groups, restoration was carried out using nanocomposite resin using the total-etch Tetric N bond adhesive. The samples were thereafter subjected to a shear bond strength test at a cross-head speed of 1 mm/min until bond failure occurred, utilizing the universal testing machine. The one-way ANOVA test and the post hoc test were used to evaluate the data for pairwise group comparisons. Compared to the control group, all groups showed lower shear bond strength to dentin, irrespective of the type of liner. Apacal ART showed higher shear bond strength followed by giomer and biodentin. However, there's no apparent statistical difference between the groups.

Comparison of two different caries risk assessment tools for infants and toddlers - A cross-sectional study.

CONTEXT: One of the essential components for successful caries management is caries risk assessment (CRA). Among CRA tools (CRATs) published in the literature: Caries management by risk assessment (CAMBRA) 123 and American Academy of Pediatric Dentistry (AAPD) CRATs are specifically designed for infants and toddlers. AIMS: The aim of this study is to compare readily available internationally accepted CRAT for infants and toddlers and check the usability of these tools in assigning caries risk among the Indian population. SETTINGS AND DESIGN: The study was conducted at Baby Oral Health Promotion Clinic, Department of Pediatrics, Tertiary Care Hospital using a cross-sectional study design. SUBJECTS AND METHODS: Data were collected using CAMBRA 123 and AAPD CRATs from 379 children aged 0-6 years. The caries risk of the children was recorded with each CRAT and a comparison was made between the two tools used. STATISTICAL ANALYSIS USED: The percentage of agreement and Cohen's kappa coefficient were used to know the agreement between the CAMBRA 123 and AAPD CRATs using the SPSS statistical tool. The significance level was set at 5% (α = 0.05). RESULTS: For children aged <2 years, the study showed slight agreement between the CAMBRA 123 and AAPD, whereas, for children more than 2 years, there was a fair agreement between the two methods which was statistically significant. This indicates that the agreement between the two methods is still not perfectly established, and AAPD CRA assigns a higher risk category than CAMBRA 123. CONCLUSIONS: CAMBRA 123 is a promising user-friendly quantitative method for CRA in clinical practice. Since there is ambiguity in assessing the caries risk in children <2 years, there is a need to establish a CRAT that can be used exclusively for children below 2 years.

Evaluation of the Relationship between Body Mass Index, Dental Caries, and Diet among a Group of 6-12 Years Old School Going Children.

Aim: These results are from research conducted on a sample of healthy school-aged children (ages 6-12) to determine whether or not there is a correlation between BMI, dental caries, and food. Method: About 500 kids are a part of the study. A stature meter was used to get the tallest possible measurement, and a small electronic scale was used to get the smallest possible weight. Body mass index was determined using the standard CDC growth charts (2000). The presence of caries was evaluated using an intraoral examination guided by WHO (1997) standards. For three days in a row, including the weekend, participants recorded what they ate and drank. Result: It was discovered that there is a huge gap in the body mass index (BMI) categories between sexes, with the vast majority of persons falling into the average weight category. The deft and DMFT caries scores of young men and women did not significantly differ across any of the BMI-for-age categories (P > 0.05). Consumption of supplements on a daily basis did not vary significantly between the BMI-for-age categories (P > 0.05). Conclusion: Pediatric dentists should play an active role in reducing this worldwide epidemic since pediatric obesity and dental caries have comparable causes and necessitate an all-encompassing, coordinated care strategy from interdisciplinary medical teams.

Effect of NaOCl on cyclic fatigue resistance.

The impact of 5.25 percent NaOCL on the resistance offered by TruNatomy, Hero Gold and ProtaperGold against cyclic fracture as against the treatment of NiTi rotary files with distilled water is of interest to dentists. Inside the stainless steel blocks, man-made canals were created for the purpose of testing the cyclic fatigue. 60 endodontic files were taken as study specimens. It was observed that values of number of cycles to fracture in NaOCl among three file systems were in the order of TruNatomy (1053.50 ± 134.81)>Hero Gold (652.66 ± 58.66) > ProtaperGold (494.50 ± 47.69). The TruNatomy file system reflected greatest cyclic fatigue resistance. It was also found that cyclic fatigue resistance in NiTi rotary files studied here is not hampered by 5.25% NaOCl.

Comparative Evaluation of Adhesive Bond Strength of Conventional GIC and Cention N to Enamel and Dentin of Primary Teeth: An In Vitro Study.

Aim: The aim of this in vitro study was to evaluate and compare the adhesive bond strength of conventional glass ionomer cement (GIC) and Cention N to the primary enamel and dentin using an accelerated fatigue test. Materials and methods: A total of 30 sound human primary molars were collected and were mounted on a metal cylindrical block using acrylic resin, embedding the root up to cemento-enamel junction (CEJ). Proximal box was prepared on both mesial and distal surfaces, one of the cavity was restored with GIC (Type 9) and the other proximal cavity with Cention N. A nonretentive cavity design was followed for both the materials so as to maintain the uniformity between the two specimens were then placed under a universal testing machine (Instron) and subjected to accelerated cyclic loads till a separation fracture occurs at the tooth-restoration interface. The number of endured cycles a particular restoration could withstand before getting fractured was registered. Results: Cention N resisted significantly more number of endured cycles before separation from the cavity as compared to GIC (p < 0.001). Conclusion: Within the limitations of the study, it can be concluded that newly developed material Cention N is preferred alternative over conventional GIC for the restoration of proximal cavities in primary molars.

Quantification and Measurement of Changes in Anxiety Level in Preschool Children and Their Mothers through Multiple-visit Dental Treatment.

AIM: The aims of the present study were to quantify anxiety and find the level of anxiety in the very 1st day of dental treatment and the pattern of change in the following visits and to find possible impact of maternal anxiety during dental treatment of their wards. MATERIALS AND METHODS: The study was conducted on 297 children aged 3-6 years visiting the Department of Pedodontics and Preventive Dentistry of Dr. R. Ahmed Dental College and Hospital for treatment. In addition, accompanying parents were also included in the study. The blood pressure and heart rate of the participants were recorded at three visits with a digital blood pressure and heart rate monitor with wrist cuff (Omron; Japan). The same instrument and the same procedure were employed for the mothers also. Blood pressures and pulse rates so recorded were tabulated according to age and were made ready for statistical analysis using the SPSS version 12 (Statistical Package for Social Sciences, SPSS Inc., Chicago, Illinosis, USA) software. RESULTS: There was a significant difference in blood pressure and heart rate of children in the subsequent visits. CONCLUSION: The majority of the children suffered from anxiety on the 1st day of treatment which gradually diminished in the subsequent visits. Maternal anxiety was also highest in the initial visit which gradually came down in the subsequent visits.

Knowledge, Attitude and Practice toward Infant Oral Healthcare among the Pediatricians of Mysore: A Questionnaire Survey.

BACKGROUND: The aim of this study was to study the knowledge, attitude and practice of the pediatricians toward infant oral healthcare and the objective was to determine what can improve the knowledge, attitude and practice toward infant oral healthcare. MATERIALS AND METHODS: A systematic random survey of pediatricians in Mysore received a questionnaire pertaining to individual details, knowledge level and approach toward infant oral healthcare. RESULTS: Most of pediatricians acknowledged the importance of pediatric dentistry. Pediatricians agree that it is important to do dental examination before 1 year. The importance of initiating oral hygiene practice before the eruption of first tooth was not seen to be prevalent among the pediatricians. Most of them were less aware of the first dental visit including early childhood caries (ECC). All pediatricians agree that both medical and dental professionals together are responsible for infant oral healthcare. They should work together to appropriately educate and train themselves to be able to provide risk assessment and to provide preventive oral health services.

Does Hollowing of Complete Denture Enhance Retention? - A Pilot Study.

INTRODUCTION: Prosthetic rehabilitation is an extremely challenging task in extreme resorption cases of the maxillary denture-bearing area. Reducing the weight of a maxillary obturator has been seen as beneficial. But whether reducing the weight of conventional complete denture also increases retention or not, is still very dubious. The aim of this pilot study was to determine the effect of maxillary denture weight on denture retention and stability. MATERIALS AND METHODS: For this study, a total of 10 patients were considered for the pilot study (06 female and 04 male) with an average age of 70 y. Each patient was provided with two sets of maxillary complete dentures, one hollow labeled as A and one conventional maxillary denture labeled as B. RESULTS: It was shown that mean values for retention using MKIS for retention for hollow dentures (A) was 7.8 and for conventional dentures (B) it was 8.2 and the stability for maxillary dentures was more with conventional dentures (B) than hollow maxillary dentures (A) and it was significant as p-value was 0.015 (p<.1). CONCLUSION: The denture retention and stability, chewing and comfort values of conventional dentures and hollow dentures were slightly better for conventional dentures.

Evaluation of the Load-bearing Capacity of Fractured Incisal Edge of Maxillary Permanent Central Incisors restored with a Glass Fiber-reinforced Nanocomposite: An in vitro Study.

OBJECTIVES: The aim of this study was to evaluate and compare the load-bearing capacity of fractured incisal edge of maxillary permanent central incisors restored with a nanocomposite and a glass fiber-reinforced nanocomposite. MATERIALS AND METHODS: Thirty-six extracted sound maxillary central incisors randomly divided in three groups were used for the present study. Group I (control) contained untreated teeth. Samples in experimental groups II and III were prepared by cutting the incisal (one-third) part of the crown horizontally and subjected to enamel preparations and restored with a nanocomposite and a glass fiber-reinforced nanocomposite respectively. All restored teeth were stored in distilled water at room temperature for 24 hours. Fracture resistance was evaluated as peak load at failure (Newton) for samples tested in a cantilever-bending test using Hounsfield universal testing machine. Failure modes were microscopically examined. RESULTS: Highest mean peak failure load (Newton) among experimental groups was observed in glass fiber-reinforced nano composite group (863.50 ± 76.12 N) followed by nanocomposite group (633.67 ± 40.14 N). One-way analysis of variance (ANOVA) revealed that the restoration technique significantly affected the load-bearing capacity (p < 0.001). Scheffe's post-hoc comparison test (subset for α = 0.05) revealed that there was significant difference in the mean peak failure load values of nanocomposite and glass fiber-reinforced nanocomposite groups when considered together (p < 0.001). Experimental groups showed similar types of failure modes with majority occurring ascohesive and mixed type. Fifty-eight percent of the teeth in glass fiber-reinforced nanocomposite group fractured below the cementoenamel junction. CONCLUSION: By using fiber-reinforced composite substructure under conventional composites in the repair of fractured incisors, the load-bearing capacity of the restored incisal edge could be substantially increased.

Bilateral mandibular paramolars.

Supernumerary tooth is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. They can cause a variety of complications in the develo-ping dentition. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. Here is the presentation of a case of unusual location of supernumerary teeth located in between mandibular first and second molar region bilaterally.

Molariform mesiodens in primary dentition: a case report.

A supernumerary tooth is a developmental anomaly and it has been argued to arise from multiple aetiologies. Mesiodens is a midline supernumerary tooth which is commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause an ectopic or a delayed eruption of permanent central incisors, which will further alter occlusion and may compromise aesthetics and formation of dentigerous cysts. This paper reports a rare case which had the presence of a molariform mesiodens in the primary dentition. The treatment plan consisted of extraction of the supernumerary tooth and regular observation of permanent central incisors for proper eruption and alignment.

Pathogenesis and nomenclature of odontogenic carcinomas: revisited.

Odontogenic carcinoma is rare group of malignant epithelial odontogenic neoplasms with characteristic clinical behavior and histological features, which requires an aggressive surgical approach. The pathogenesis of this rare group remains still controversial and there have been many varied opinions over the classification of this rare group of lesions. As there have not been many reviews on odontogenic carcinoma, the existing knowledge is mostly derived from the published case reports. This review is discussing the pathogenetic mechanisms and is updating the knowledge on nomenclature system of less explored odontogenic carcinomas. This review might throw light on the pathogenesis and nomenclature system of odontogenic carcinoma and this knowledge may be applied therapeutically.

Oro-facial-digital syndrome type 1: a case report.

Oro-Facial Digital Syndrome (OFDS) is a generic term for group of apparently distinctive genetic diseases that affect the development of the oral cavity, facial features, and digits. One of these is OFDS type I (OFDS-I) which has rarely been reported in Asian countries. This is the case report of a 13 year old patient with OFDS type I who reported to the Department of Pedodontics and Preventive Dentistry, with the complaint of discolored upper front teeth.

Bilateral maxillary paramolars: a case report.

Supernumerary teeth are a common clinical and radiographic finding and may produce occlusal and dental problems. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. The purpose of this paper was to present a case of supernumerary teeth located in the maxillary molar region bilaterally.

Modified distal shoe appliance for the loss of a primary second molar: a case report.

Preservation of primary teeth until their normal exfoliation plays a crucial role in preventive and interceptive dentistry. Premature loss of the primary second molar prior to the eruption of the permanent first molar in the absence of the primary second molar can lead to mesial movement and migration of the permanent molar before and during its eruption. In such cases, an intra-alveolar type of space maintainer to guide the eruption of the permanent first molar is indicated. In certain cases, however, the conventional design is not practical. This paper describes a new design for distal shoe appliances in cases of primary second molar loss prior to the eruption of the permanent mandibular first molar.

Comparative evaluation of fluoride release from PRG-composites and compomer on application of topical fluoride: an in-vitro study.

AIMS AND OBJECTIVE: To determine the fluoride release from Giomer and Compomer, using different topical fluoride regimes, and to compare the amount of fluoride release from giomer with that of compomer. MATERIALS AND METHOD: Forty-eight specimens of each giomer and compomer were divided into four treatment groups, namely, control group, fluoridated dentifrice (500 ppm) once daily group, fluoridated dentifrice (500 ppm) twice daily group, fluoridated dentifrice (500 ppm) once daily + fluoridated mouthwash (225 ppm) group. Each specimen was suspended in demineralizing solution for six hours and remineralizing solution for 18 hours. Fluoride release was measured in both the demineralizing solution and remineralizing solution daily for seven days. Total daily fluoride release for each specimen was calculated by adding the amount released in the demineralizing solution to that released in remineralizing solution. RESULTS AND CONCLUSION: The fluoride release (ppm) was found to be more in Giomer when compared to Compomer. The fluoride released from Giomer and Compomer was significantly greater in the acidic demineralizing solution than in the neutral remineralizing solution. It was found that increasing fluoride exposure significantly increased fluoride release from the giomer and compomer. It was found that the fluoride release from the subgroups of giomer and compomer was in the following order: fluoridated dentifrice twice daily > fluoridated dentifrice once daily + fluoridated mouthwash > fluoridated dentifrice once daily > control group. It was found that the giomer showed a greater fluoride uptake than the compomer.
