Classification systems of gingival recession: An update
Sanjeev Jain, Harjit Kaur, Ridhi Aggarwal
January-March 2017, 9(1):52-59
DOI:10.4103/0976-4003.201632  
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.

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.

Platelet-rich fibrin or platelet-rich plasma – which one is better? an opinion
Shweta Bansal, Arun Garg, Richa Khurana, Parul Chhabra
September 2017, 9(5):49-52
DOI:10.4103/IJDS.IJDS_55_17  
The healing of hard and soft tissue in mediated by a wide range of intracellular and extracellular events that are regulated by signaling proteins. Platelets can play a crucial role in periodontal regeneration as they are the reservoirs of growth factors and cytokines which are the key factors for regeneration of bone and maturation of soft tissue. Platelet-rich plasma (PRP) is first generation platelet concentrate. However, the short duration of cytokine release and its poor mechanical properties have resulted in search of new material. Platelet-rich fibrin (PRF) is a natural fibrin-based biomaterial prepared from an anticoagulant-free blood harvest without any artificial biochemical modification (no bovine thrombin is required) that allows obtaining fibrin membranes enriched with platelets and growth factors. The slow polymerization during centrifugation, fibrin-based structure, ease of preparation, minimal expense makes PRF somewhat superior in some aspect to PRP.

DOI:10.4103/IJDS.IJDS_18_17  
Plaque control is the daily removal of dental plaque, oral biofilm and also prevention of their accumulation on the teeth and other parts of oral cavity. Dental plaque is the major etiology of maximum gingival and periodontal diseases. It is also related with various dental problems. Mechanical plaque control is a very effective method to get rid of plaque accumulation in oral cavity. In 3000 BC there was the first toothbrush invented by human beings. With time several modifications came in toothbrushes to make mechanical plaque control more effective in day to day oral hygiene practice. This article emphasizes on the advanced and emerging tools in mechanical plaque control methods in attaining an optimal level of oral hygiene standards and maintenance of oral health.

Smoking and its effect on periodontium – Revisited
Gurparkash Singh Chahal, Kamalpreet Chhina, Vipin Chhabra, Amna Chahal
January-March 2017, 9(1):44-51
DOI:10.4103/IJDS.IJDS_96_16  
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.

Nazia Masoom Syed
July-September 2016, 8(3):176-182
DOI:10.4103/0976-4003.191726  
Vascular lesions are among the most common congenital and neonatal abnormalities. These anomalies can occur throughout the whole body, with 60%, however, being located in the head and neck region probably due to its intricate vascular anatomy of region. There is a significant confusion in the literature because of the use of confusing descriptive terminology for the same vascular entity and eponyms. Correct naming of lesion, appropriate classification, and clinical appearance of vascular lesions have a direct impact on understanding of etiologies of these complex lesions, diagnosis, and in treating patients. Thus, the aim of this article is to provide comprehensive knowledge about classifications and to have an insight of various important vascular lesions affecting head and neck region based on its pathogenesis, clinical presentation, and management.

Vipin Agarwal, Sunny , Nidhi Mehrotra, Vivek Vijay
January-March 2017, 9(1):12-15
DOI:10.4103/0976-4003.201639  
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.

Oral fluid-based biosensors: A novel method for rapid and noninvasive diagnosis
K Roja Lakshmi, Hasini Nelakurthi, A Sudarshan Kumar, Amrutha Rudraraju
January-March 2017, 9(1):60-66
DOI:10.4103/IJDS.IJDS_6_17  
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.

DOI:10.4103/IJDS.IJDS_33_17  
Objectives: The study aimed to check the age- and gender-wise prevalence of oral habits in the children of 7–16-year-old Indian children. Materials and Methods: A cross-sectional survey involving 1029 (661 males and 368 females) children of age 7–16 years was done to record the presence or absence of the oral habits with the aid of the anamnestic questionnaire. The recorded oral habits were tongue thrusting, thumb or digit sucking, mouth breathing, bruxism, lip biting or lip sucking, and nail biting. The collected data were subjected to Pearson's Chi-square statistical analysis to know the overall difference in the prevalence rate of different oral habits and to evaluate the gender- and age-wise difference in the prevalence of oral habits. Results: Oral habits were present in 594 participants (57.73%). The highest prevalence rate was registered for tongue thrusting habit (28.8%), which was followed by nail biting (201/19.5%) and thumb sucking (128/12.4%), mouth breathing (109/10.6%), lip biting (85/8.3%), and bruxism (29/2.8%). The male participants showed a greater prevalence rate for the oral habits than the female participants (58.55% vs. 56.25%). There was a significant difference in the age-wise prevalence of oral habits with older children showing greater prevalence of oral habits than the younger ones. Conclusion: The prevalence of oral habits in the current group of children is high. It warrants the need for the community-based educational preventive and interceptive programs to spread the awareness regarding the deleterious effects of these oral habits.

Prosthetic rehabilitation of an amputated finger
Meenu Garg, Chetan Pathak, Sonal Batra Tangri, Amit Gupta
July-September 2016, 8(3):163-167
DOI:10.4103/0976-4003.191734  
Amputation of finger causes devastating physical, psychosocial, and economic damage to an individual. The concealment of an amputated part with the help of prosthesis can shield an amputee from social stigma. Prosthesis for such patient must be comfortable to wear lightweight, durable, cosmetically pleasing easy to put on and remove. The restoration of finger amputations depends on the amount of tissue involved, the involvement of bone, the angles and levels of amputation, and the involvement of other fingers. The microsurgical reimplantation helps to save many severely injured and traumatically amputed finger. The prosthetic rehabilitation of an amputated finger is considered when microvascular reconstruction is not possible, unavailable, unsuccessful, or unaffordable. Most accepted material is silicones because of their better esthetics, ease of manipulation, and availability. This paper presents prosthetic rehabilitation of index finger of the right hand with custom made silicon prosthesis.

Can infection with the dental caries pathogen, Streptococcus mutans, be intercepted or modified immunologically? Resolving this question requires answer to many questions: What are the pathways by which this cariogenic streptococcus enters and accumulates in the dental biofilm? Can bacterial components associated with virulence induce immune responses? What is the level of maturity of immune pathways in the oral cavity of the young child at the time of infection? Many such questions have been answered. For example, preclinical application of modern methods of mucosal vaccine design and delivery has routinely resulted in protection from dental caries caused by S. mutans infection, using antigens involved in the sucrose-independent or sucrose-dependent mechanisms of infection by these cariogenic streptococci. Passive administration of antibody to functional epitopes of S. mutans virulence antigens has also provided a degree of protection in preclinical studies and small-scale human investigations. The caries-protective capacity of active immunization with dental caries vaccines now awaits proof of principle in pediatric clinical trials.

DOI:10.4103/IJDS.IJDS_34_17  
Maxillary Antrolith is a rarely found calcified mass that occurs in the maxillary sinus formed by exogenous or endogenous origin. Stones arising in the antral cavities are uncommon, and their development is similar to that of a sialolith. We report a case of 55 yr. old male who came with h/o heaviness on right cheek region, nasal discharge and headache since 1 month. On evaluating the PNS radiograph shows the radiopacity in the right maxillary sinus. Caldwell-luc operation was done and the calcified masses (antroliths) along with antral polyps were removed. We report this case because of its rarity. The etiology, clinical and radiographic aspects and differential diagnosis of antrolith are also discussed.

DOI:10.4103/0976-4003.196813  
Background: The purpose of the study was to compare clinical efficacy of nonsurgical periodontal therapy with hand scaler, conventional ultrasonic scaler, and Vector ultrasonic system in patients with generalized chronic periodontitis. Materials and Methods: Sixty patients with generalized chronic periodontitis fitting the inclusion and exclusion criteria were assigned to one of the three treatment groups (n = 20 in each group). Group I – hand scalers, Group II – conventional ultrasonic scalers, and Group III – Vector™ ultrasonic system. Before oral prophylaxis, clinical parameters (gingival index [GI], plaque index [PI], calculus index [CI], periodontal probing depth [PPD], clinical attachment loss [CAL], and hypersensitivity) were recorded. GI, PI, CI, and hypersensitivity were reevaluated at 1, 3, 6 and 12 weeks. PPD and CAL were reevaluated at 6 and 12 weeks. Results and Conclusion: The results showed that nonsurgical therapy with Vector ultrasonic system is clinically comparable in all the parameters, to hand and conventional ultrasonic scalers, suggesting that it can be used as a gentle root debridement device for supportive periodontal therapy, as an alternative to other ultrasonic or sonic scalers.

Infant oral health care: An invaluable clinical intervention
Kanika Singh Dhull, MD Indira, Rachita Singh Dhull, Bhavya Sawhney
July-September 2016, 8(3):183-186
DOI:10.4103/0976-4003.191736  
Dental assessments and evaluations for children during their 1st year of life have been recommended by the American Academy of Pediatric Dentistry and the American Association of Pediatrics. Early dental intervention evaluates a child's risk status based on parental interviews and oral examinations. These early screenings present an opportunity to educate parents about the medical, dental, and cost benefits of preventive rather than restorative care and may be more effective in reducing early childhood caries than traditional infectious disease models. A comprehensive infant oral care program includes: (1) risk assessments at regularly scheduled dental visits, (2) preventive treatments such as fluoride varnishes or sealants, (3) parental education on the correct methods to clean the baby's mouth, and (4) establishment of dental home and use of anticipatory guidance. The present article highlights the important guidelines of infant oral health care.

Bilateral buccal exostosis evaluated by cone-beam computed tomography: A rare accidental finding
Humaira Siddiqui, Dhirendra Kumar Singh, Silpiranjan Mishra, Arnab Mandal
January-March 2017, 9(1):34-37
DOI:10.4103/IJDS.IJDS_95_16  
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.

DOI:10.4103/IJDS.IJDS_26_17  
Aim: This study aims to evaluate the flexural strength, hardness, and impact strength of heat-cured high-impact denture base resins with different polymer/monomer ratios. Materials and Methods: A total of 150 acrylic samples were prepared using high impact denture base resin (Travelon Hi). The samples were divided into five groups based on different powder/liquid ratios (g/ml) with 30 samples in each group. The P/L ratio in Group 1 (Ratio - 2.2:1) was the manufacturer's recommended ratio and was used as control. In Group 2, the ratio was 2.7:1, in Group 3, the ratio was 3.2:1, in Group 4, the ratio was 1.9:1, and Group 5 the ratio was 1.6:1. Each group with 30 samples was further subdivided into three different subgroups comprising 10 samples each, based on the properties to be evaluated, i.e., for flexural strength, hardness, and impact strength evaluation. The samples were tested for flexural strength, Vicker's hardness number (VHN) and impact strength. One-way ANOVA including post hoc-Tukey's tests was used to calculate the difference of means for quantitative variables and for intergroup comparison as well. Results: The results showed that the flexural strength values and VHN values showed a similar trend. The values decreased significantly as the ratio was increased or decreased from the control group. The results also showed that there was nonsignificant difference between the mean impact strength values for all the groups. Conclusion: For reinforced resins or high impact resins, the manufacturer's recommended polymer/monomer mixing ratio should be used to obtain the appropriate strength of the material.

DOI:10.4103/IJDS.IJDS_62_17  
Cosmetic surgery is not a new thing. The boom of cosmetic surgery is at its pace in India; people have been getting habituated to esthetics for so many years. Esthetic adjustment of various body parts such as rhinoplasty and lip modifications are more common nowadays. A dimple is a small depression on the surface of the body which can be easily noticeable; people appreciate the presence of dimple on the face and believe that it is a sign of good fortune and prosperity. With the advancements in the cosmetic surgery, there has been a upsurge in having artificial dimple on face. With this increased demand in having facial dimples in people, surgeons now are in an idea of creating an artificial dimple with dimple surgery or “dimpleplasty.” The procedure of dimpleplasty is as simple as making a cut in the skin, suturing the underside of the skin to a deeper layer to create a small depression. The suture creates a permanent scar which maintains the dimple. It is a thumb rule that any surgery has minor risks which are avoidable; the current review enumerates the various procedures for dimpleplasty and their outcomes. This article emphasizes on routine as well as recent procedures used for dimpleplasty and its relative complications.
