Background: Dental caries is one of the most common oral problems affecting children globally involving the people of all region and society. It can be seen in all age groups of children involving both deciduous and permanent teeth. Dental caries is a lifetime disease, and the highest priority risk group is between 6 and 12 years of age. Aims: The aim of the study was to evaluate the prevalence of dental caries in both primary and permanent dentition among the school-going children in Mahbubnagar district. Materials and Methods: A cross-sectional study was carried out in 2000 children in different areas of Mahbubnagar district in age group 6–12 years. The dental caries status was assessed by decayed, missing, and filled teeth (DMFT)/dmft index using the World Health Organization criteria 1997. Statistical Analysis: Collected data from each patient is subjected to statistical analysis to know the prevalence of dental caries. Results: Dental caries in both primary dentition and permanent dentition was 64.2% and 26.6%, respectively. The prevalence of dental caries in primary dentition was more in 7–8-year-old children and less in 11–12-year-old children (P > 0.05). Overall, mean dmft score of both males and females is 1.49 ± 1.56, the overall mean DMFT score of both males and females is 0.57 ± 1.23. Conclusion: The present study showed that the frequency of caries was found to be a higher in the Northern region of Mahbubnagar district. The dental caries was more in 7–8 years and less in 11–12 years children, whereas less in local villages of Mahbubnagar.

Aim: This study aims to evaluate and compare the fracture resistance of endodontically treated teeth obturated with gutta-percha using two sealers, AH Plus, and mineral trioxide aggregate (MTA) Fillapex. Materials and Methods: Twenty single-rooted mandibular premolars, decoronated at cementoenamel junction, were divided into two groups (n = 10 each). Cleaning and shaping of root canals were done using ProTaper rotary files and 3% sodium hypochlorite irrigation. Obturation was done using sealers, AH Plus (Dentsply, Germany) in Group 1 and MTA Fillapex (Angeles, Brazil) in Group 2 and gutta-percha. The teeth were subjected to vertical loading using a universal testing machine, and the readings were recorded at the point at which fracture of the roots occurred. The data were subjected to statistical analysis followed by pairwise comparison using Tukey's post hoc test. Results: According to the study, it was found that AH Plus showed better fracture resistance than MTA Fillapex. Statistically, no significant difference was found between the two groups. Conclusion: AH Plus and MTA Fillapex gave comparable results as root canal sealers.

Background: An adequate width of the attached gingiva helps in maintaining esthetics and proper plaque control. A thin gingiva may lead to recession after trauma or surgical and inflammatory injuries, thus sufficient thickness of the attached gingiva is desirable. Studies have shown considerable intra- and inter-examiner variation in both width and thickness of attached gingiva, which might be due to the presence of different gingival biotypes present in the adult population. By ascertaining gingival thickness, we can diagnose periodontal diseases and plan a proper treatment which is important for a good prognosis. Aims: The aim of the study is to evaluate the variations in the thickness of gingiva with respect to age, gender, and location in the dental arch. Materials and Methods: A total of 90 (45 males and 45 females) periodontally healthy subjects were divided into three different age groups. These individuals were examined for their gingival thickness in the maxillary and mandibular arches. Results: It was observed that the thickness of gingiva significantly decreased with age in both the arches and was significantly higher in females than males. The maxillary arch had thicker gingiva as compared to mandibular arch. Conclusion: In the present study, we concluded that the thickness of the gingiva varies with age, gender, and arch location.

Background and Aims: Removable complete denture is one of the most common treatment modalities for completely edentulous patients. After denture insertion, patient very often faces problems with the denture even after complete care is taken during fabrication procedure. Most common complaint is traumatic ulcers. The present study aimed to locate the most common areas of ulcerations due to complete dentures, how frequently they occur and how many times patient visits for adjustment after insertion of complete denture. Materials and Methods: Two hundred and twenty-one patients were selected and were delivered complete dentures. Dentures were fabricated for all the patients. Each step of denture fabrication was controlled and guided by a prosthodontist. After placement of dentures, patients were evaluated at every recall visit and their dentures were adjusted. All the details of each visit (area of ulceration) and number of visits were recorded in a self-designed format. Descriptive statistical analysis was done using SPSS version 13 software. Chi-squared test was used to evaluate the correlation between mucosal injuries and postinsertion day and the relationship between lesions, patient age, and patient gender. Results: All the 221 patients required denture adjustment due to mucosal injuries. No significant difference was found between denture-related injuries between males and females. Injuries related to mandibular dentures were significantly higher than those related to maxillary dentures. In mandible, the most common area of mucosal injury is posterior one-third of alveololingual sulcus; while in maxilla, the most common area of mucosal injury is labial frenum. Conclusion: Postinsertion adjustments are an important aspect of rehabilitating patient with complete dentures. Most of the denture-related injuries were in limiting areas. Proper border molding techniques, accurate secondary impressions, and use of pressure indicating paste during denture insertion are main requisites for decreasing denture-related mucosal injuries.

Context: Oral health is essential for elderly person's general health and well-being. The most common oral problem in elderly is tooth loss which results due to periodontal diseases and caries. Prosthetic status is very important as it is related to dietary intake and maintaining nutritional status. Hence, to promote the oral health of the elderly, we need to know their prosthetic status and need. Aims: The aim of this study is to find the prosthetic status and need of 65–74 years old elderly residing in old age homes of Delhi, India. Settings and Design: A cross-sectional study was conducted among a total of 464 residents of 20 old age homes of Delhi, India. Material and Methods: Residents with age group of 64–75 were included in the study. The prosthetic status with treatment need was recorded using the World Health Organization Oral Health Assessment Form (1997). Statistical Analysis Used: Chi-square test and t-test were used to find significance of variables. P < 0.05 was considered significant. Results: Full removable dentures were worn by 7.30% of participants with predominance in upper arch, and one bridge was seen in 9.10% of participants with predominance in lower arch. Full removable denture was required in 25.20% of participants. Most of participants required multiunit prosthesis in both upper as well as lower arch (42.20% and 36.20%, respectively). Conclusion: The present study underlines a considerable need for dental treatment in elderly as the prosthetic status of participants was poor, and prosthetic needs were high.

Background: Calcium hydroxide (Ca(OH)₂) is the most commonly used intracanal material; it needs to be removed in entirety before obturation. Several techniques have been used for the same including use of various hand and rotary files. Aim: This study was carried out to compare the efficacy of Hand K files and single and multiple rotary file system in removal of Ca(OH)₂. Methodology: Distobuccal root of 45 maxillary molars were selected on the basis of specified inclusion and exclusion criteria. They were divided into three groups - Group 1 (H and K file), Group 2 (HERO Shaper), and Group 3 (One Shape). Biomechanical preparation (BMP) was carried out as per the manufacturer's instructions; 2.5% sodium hypochlorite was used as the irrigant and 17% ethylenediaminetetraacetic acid as the penultimate irrigant. Ca(OH)₂powder was mixed with normal saline to obtain a paste; canals were filled with this paste using a Lentulo spiral and were sealed. After 7 days, Ca(OH)₂was removed, using the same file system as that used for BMP. Samples were sectioned longitudinally and evaluated under a stereomicroscope. Statistical Analysis: Statistical analysis of the obtained data was carried out using one-way analysis of variance test. Results: HERO Shaper displayed better removal of Ca(OH)₂than One Shape and Hand K file. Moreover, removal was better in the middle third of canal than apical third. Conclusion: Multiple rotary file system (HERO Shaper) is more effective in removal of Ca(OH)₂than the single file system (One Shape)

Introduction: Amalgam, the most commonly used restorative material, is composed of nearly 50% mercury and 69% silver. It cannot be disposed along with biomedical waste (BMW) because mercury-contaminated waste cannot be incinerated or autoclaved. Objectives: To assess the knowledge and observance of proper mercury hygiene and amalgam waste management among general dental practitioners (GDPs). Materials and Methods: A confidential questionnaire containing 14 questions regarding handling and disposal of amalgam was randomly distributed to 175 GDPs in Chandigarh, Panchkula, and Mohali. A response rate of 78% was obtained, and results were statistically analyzed. Results: Out of total dentists surveyed, 71% were found to be using amalgam as restorative material, 63% were doing <5 amalgam restorations per week. Only 6.5% of dentists placed rubber dam during removal and replacement of amalgam restorations. Fifty-five percent of dentists used high-volume evacuation. Filter was used only by 6% dentists. For 98%, dentists' evacuation drained into regular drain. Eighty-six percent of dentists never used amalgamator. Only 31% of dentists stored leftover amalgam scrap in radiographic fixer. Fifty-one percent of dentists disposed the bottle of leftover amalgam scrap along with BMW. One hundred percent of dentists disposed amalgam-contaminated gloves and cotton along with BMW. Only 17% of GDPs periodically monitored mercury vapors in their dental operatories. Conclusion: There exists a significant lack of knowledge regarding mercury hygiene and amalgam waste disposal among GDPs. Guidelines on mercury management need to be strongly implemented to prevent contamination of environment by mercury.

Buccal exostoses are broad-based, non-malignant surface growth occurring on the outer or facial surface of the maxilla and/or mandible, found usually in the premolar and molar region. Etiology is still not established, but it has been suggested that the bony overgrowth can be because of abnormally increased masticatory forces to the teeth. Compensatory response to periodontal disease has been proposed to explain some cases of exostoses; they tend to appear in early adolescence and may very slowly increase in size with time. They are painless, self-limiting and may increase patient concern about poor esthetics, inability to perform oral hygiene procedures, and compromised periodontal health by causing food lodgment. The following article presents a very rare case of bilateral buccal-sided maxillary and mandibular exostoses in the anterior region which was an accidental finding in a chronic generalized periodontitis patient.

The history of operative dentistry dates back to the era when Babylonians, Assyrians, and Egyptians (4500–4000 BC) were familiar with gold, and Etruscans and Phoenicians (2700 BC) were practising gold crowns. Since then, there have been numerous advances, developments, and researches which have proceeded continuously. These inventions have transformed the practice of operative dentistry into one which is more efficient and more comfortable for the patients as well as for the operating team. This article highlights the significant advancements in the field of operative dentistry which have occurred over a period of time and have helped us to serve our patients better.

Cigarette smoking represents a major preventable cause of human disease. Smokers have significantly elevated risks of all-cause mortality and developing a variety of pathological conditions. A direct causal relationship between smoking exposure and the prevalence and the severity of periodontal disease has been firmly established. Although the direct cause for periodontitis is oral bacterial infection, smoking is arguably the strongest behavioral risk factor for the incidence and progression of periodontitis. Smoking has a deleterious effect on all the aspects of periodontium. Smokers have been shown to respond less well to nonsurgical as well as surgical therapy than nonsmokers. Based on this evidence, dental health professionals should advise patients about tobacco's negative health effects as well as the benefits of quitting tobacco use, and tobacco cessation counseling should be a part of the armamentarium of the dental office.

Gingival recession is defined as “the displacement of marginal tissue apical to the cementoenamel junction (CEJ)”. Various classifications have been proposed to classify gingival recession. Miller's classification of gingival recession is most widely followed. With a wide array of cases in daily clinical practice, it is often difficult to classify numerous gingival recession cases according to defined criteria of the present classification systems. This article outlines the limitations of present classification systems and also the new classifications that have been proposed to classify gingival recession.

In the recent times, chair-side/bed-side monitoring tests have gained importance over the routine laboratory tests as they are easier and faster to perform without requiring skilled personnel. Biosensors refer to such type of point-of-care devices that are developed to help in the early diagnosis, periodic monitoring, and treatment of disease. These devices utilize biological reactions for detecting and measuring a particular substance (analyte) of interest. Till date, blood has been the gold standard diagnostic fluid for various diseases. However, oral fluids such as saliva and gingival crevicular fluid offer advantages such as noninvasive collection of sample, smaller sample aliquots, easy storage and transportation, repeated sampling for monitoring over time, and greater sensitivity, making them an alternative clinical tool over serum and tissues for many biomedical diagnostic assays. This review highlights the use of oral fluid-based biosensors for diagnosis of caries, periodontitis, oral cancer, and various systemic diseases.
