Bone resorption is a natural phenomenon and can occur due to old age, loss of teeth, prolonged denture wear, or as a result of systemic conditions. For the replacement of teeth by fabrication of prosthesis or the use of implants, a minimum amount of bone density is required. Bone grafting is a method by which bone-deficient areas are built up, with the use of different materials, such as autografts, allografts, alloplasts, and xenografts. Over recent times, the use of frozen bone matrix formulations and synthetic ceramics has been used in greater frequency. This article discusses the use of human bone material (allografts), synthetic materials (alloplasts) and blood components as successful grafting materials. Their use has shown an effective amount of bone formation and proliferation in the defective sites and proves to be a beneficial choice in bringing back lost bone.

The concept of conventional tooth-retained overdentures is a simple and cost effective treatment than the implant overdentures. When few firm teeth are present in an otherwise compromised dentition, they can be retained and used as abutments for overdenture fabrication. This helps improve the retention and stability of the final prosthesis significantly. Bone is a dynamic tissue. The extraction of teeth results in the initiation of the bone resorption pattern. However, when tensile stress is received by bone, additional bone formation takes place. Such stresses occur when occlusal forces are transmitted to the alveolar bone by the periodontal ligament. This principle helps preserve bone. The concept of overdentures may not be the elixir, but it is a positive means for delaying the process of complete endentulism and helps in the preservation of bone. To top it all, it gives the patient the satisfaction of having prosthesis with his natural teeth still present. In this article, case reports with three different types of Overdentures are discussed: Overdenture with cast copings with short dowels, O-ring attachments, and a customized bar supported overdenture with copings.

Objective: The objective of the study was to assess and compare the oral health knowledge, attitude, and behavior of medical, pharmacy, and nursing students at the University of Port Harcourt, Nigeria. Subjects and Methods: A total of 189 students including 94 males and 95 females involved in the cross-sectional surveyed. Data were collected using pretested, self-administered, structured questionnaire. The mean percentage scores, standard deviation, and frequency distribution were calculated. The Student's t-test and ANOVA test were used to test the association between variables. The linear regression analysis was used to establish any association of behavior with knowledge and attitude. Results: The total mean percentage scores for knowledge, attitude, and behavior were more than 50% among the students. The mean percentage scores for knowledge, attitude, and behavior were significantly higher for the medical students compared to pharmacy and nursing students. All the scores were significantly higher in females than in males except for the mean score of knowledge. There was no significant association between knowledge, attitude, and behavior with age. Linear regression analysis showed a significant linear relationship between behavior and attitude, but there was no significant linear relation between behavior and knowledge. Conclusion: The present study indicates that although the mean scores for knowledge, attitude, and behavior were more than 50% among the participants, the students' oral health knowledge, attitude, and behavior was inadequate and needs to be improved upon. The study also revealed that attitude is a determinant of oral health behavior among the students.

Nonsurgical therapy aims to eliminate both living bacteria in the microbial biofilm and calcified biofilm microorganisms from the tooth surface and adjacent soft tissues. Complete elimination of such pathogenic microorganisms is perhaps over-ambitious. However, a reduction in inflammation of the periodontium due to a lesser bacterial load leads to beneficial clinical changes. In addition, nonsurgical therapy aims to create an environment in which the host can more effectively prevent pathogenic microbial recolonization using personal oral hygiene methods. The concept of critical probing depth was consistently found to be greater for the surgical approach than for the nonsurgical treatment. The various methods used in nonsurgical therapy, such as hand instrumentation, ultrasonic and sonic scalers, and ablative laser therapy.

Introduction: Dental caries and periodontal diseases are multifactorial oral health problems that have dental bacterial plaque as their main etiological agent. Dental plaque removal plays an important role in oral health maintenance, which could be achieved by either mechanical or chemical plaque control. Disclosing agents in dentistry are being used to identify bacterial plaque for instruction, evaluation and research purposes. Hence, the current study is aimed at evaluating the effect of at home use of disclosing agent in improving the quality of daily oral hygiene. Materials and Methods: The present randomized, prospective case-control study was conducted among 100 subjects who were selected from the outpatient department of periodontology and divided into two groups. Group A (n = 50) is the case group who were instructed to use a disclosing agent and Group B (n = 50) is the control group who were not instructed to use a disclosing agent. Plaque status of the subjects was assessed using "Turesky-Gilmore-Glickman Modification of the Quigley Hein Plaque Index" at baseline. Both the groups were trained to perform the similar brushing technique along with same oral hygiene instructions. After 21 days, both groups were recalled, and their plaque status was re-assessed by the same method. The pre and postplaque scores of both the groups were evaluated by unpaired t-test and value of P < 0.05 was considered significant. Results: Preevaluation plaque score of Group A was 2.02 ± 0.24 and postevaluation score was 1.08 ± 0.26. Similarly in Group B, the preevaluation plaque score was 1.80 ± 0.92 and postevaluation score was 1.62 ± 0.48. The difference in the plaque scores was statistically significant with a P = 0.00001. Conclusion: The result shows that usage of plaque disclosing agent improves the quality of daily oral hygiene measures performed at home.

Aim: The distribution and severity of oral diseases are significantly influenced by oral hygiene practices. The aim of this study was to assess the oral health practices among secondary school students in Lagos State, Nigeria and investigate the influence of oral hygiene practices on caries experience. Materials and Methods: Questionnaires were administered and dental examinations conducted on 598 schoolchildren aged 11–20 years. The students were recruited from two Local Government Areas of Lagos State. Statistical significance was determined at P < 0.05 using Chi-square tests. Results: Majority of the participants (57.6%) had never visited the dentist. “Lack of pain” (31.1%) and “no reason” (42.5%) were recorded as the reason for not visiting the dentist. While toothbrush alone was used as a cleaning item by 73.9% of the students, 70.4% used fluoride-containing toothpaste, and 76.9% brush their teeth twice daily. The prevalence of dental caries was 9.7%. Caries prevalence was significantly associated with the use of fluoride-containing toothpaste (P = 0.015) and frequency of cleaning (P = 0.04). Respondents who used fluoride-containing toothpaste were about 2 times less likely to develop dental caries (odd ratio [OR] = 0.425 95% confidence interval [CI]: 0.45–1.32) and those who brush twice or more daily were 2.4 times less likely to develop caries (OR = 0.44 95% CI: 0.20–0.94). Conclusion: The oral health practices of the participants were not satisfactory. Although the prevalence of dental caries was low, it was significantly influenced by frequency of toothbrushing and the use of toothpaste containing fluoride.

Neopterin is a catabolic product of guanosine triphosphate, a purine nucleotide and belongs to the group pteridines. When the cytokine interferon gamma stimulates the human macrophages, they synthesize the neopterin. It is an indicative of a pro-inflammatory immune status and hence serves as a cellular immune system marker. In most of the diseases, in which the cellular immune system is involved, we find that the neopterin concentrations are usually high. In the periodontal diseases, the levels of neopterin usually fluctuate which is proved by its increase in disease progression and a decrease after treatment. Periodontal diseases are characterized by enhanced macrophage infiltration to the periodontal lesion, so neopterin being a macrophage activation marker may be seen in higher levels. This review deals with neopterin and its mechanism and its use as a marker in the diagnosis of the periodontal diseases.

The periodontal epithelium neighboring the tooth is precise to form a seal and attachment around the tooth. This exclusive function imparts unique challenges to the tissue and leads to certain vulnerabilities allied with periodontal disease, particularly in view of the continual exposure to the bacterial biofilm (dental plaque) that form that is formed on the tooth surface at the junction of the soft tissue. It is obvious that oral epithelial cells can counter unbroken microbial challenges from dental plaque by the production of antimicrobial peptides (AMPs), chemokines and cytokines that boost inflammation and immune response in periodontal tissues. AMPs are early responders of the innate immune system that search and destroy invading pathogens. The large variety of AMPs presumably allows for an effective response to the large variety of microorganisms that invade the mouth and airways. The present paper portrays the association between altered expression of AMPs and some types of periodontitis along with AMPs and their clinical significance in other oral diseases.

Apexification using calcium hydroxide has many disadvantages, such as, it needs more time for the treatment, chance for fracture of the tooth, and incomplete calcification of the bridge. There are many alternative treatments introduced, which have gained popularity, such as, forming an apical plug using mineral trioxide aggregate (MTA), for excellent results. In cases of wide open apices, it is difficult to limit the restoration to the working length, as such situations lead to the apical extrusion of the material into the periapical region, which prevents further healing. Such conditions can be best treated with the use of a resorbable collagen membrane, which limits the restoration till the working length and prevents the extrusion of the material beyond the apex. The present case reports highlight the non-surgical management of immature teeth by using a membrane as a barrier, with an MTA apical plug, followed by crown rehabilitation.

Human teeth may show variations which may be found on the crown, either in the form of anomalous cusps or in an increased number of roots which, in some instances, are associated with an anomalous cusp. This paper describes the incidental finding of an uncommon dental trait like “Bolk cusp” or “tuberculum paramolare” or “paramolar tubercle.” Paramolar tubercle is an additional cusp occurring on the buccal surface of a permanent maxillary molar. The presence of these extra cusps may be associated with dental problems such as caries, sensitivity, occlusal interference, and hence, there is a need for continuous dental surveillance.

Background: Class ll sandwich restorations are routinely performed where conventional Glass ionomer cement (GIC) or Resin-modified GIC (RMGIC) is used as a base or dentin substitute and a light curing composite resin restorative material is used as an enamel substitute. Various authors have evaluated the microleakage of composite resin restorations where glass ionomer cement has been used as a base in class II sandwich restorations, but a literature survey reveals limited studies on the microleakage analysis of similar restorations with biodentine as a dentin substitute, as an alternative to glass ionomer cement. The aim of this study is:

1. To evaluate the marginal sealing efficacy of a new calcium-silicate-based material (Biodentine) as a dentin substitute, at the cervical margins, in posterior class II sandwich restorations.
2. To compare and evaluate the microleakage at the biodentine/composite interface with the microleakage at the resin-modified GIC/composite interface, in posterior class II open sandwich restorations.
3. To compare the efficacy between a water-based etch and rinse adhesive (Scotch bond multipurpose) and an acetone-based etch and rinse adhesive (Prime and bond NT), when bonding biodentine to the composite.
4. To evaluate the enamel, dentin, and interfacial microleakage at the composite and biodentine/RMGIC interfaces.

Materials and Methods: Fifty class II cavities were prepared on the mesial and distal surfaces of 25 extracted human maxillary third molars, which were randomly divided into five groups of ten cavities each: (G1) Biodentine group, (G2) Fuji II LC GIC group, (G3) Biodentine as a base + prime and bond NT + Tetric N-Ceram composite, (G4) Biodentine + scotchbond multi-purpose + Tetric N-Ceram composite, (G5) Fuji II LC as a base + prime and bond NT+ Tetric-N Ceram composite. The samples were then subjected to thermocycling, 2500× (5°C to 55°C), followed by the dye penetration test. Scores are given from 0 to 3 based on the depth of penetration of the dye at the cervical, dentin, and interfacial surfaces. The data was analyzed with the nonparametric Kruskal-Wallis and Mann Whitney U test. Results: No statistically significant differences were found between the five groups in the enamel, dentin, and interfacial regions. Conclusion: Within the limits of this in vitro study, biodentine is a new calcium-silicate-based material, which can be used as a dentin substitute in class II open-sandwich restorations, where its scores better than resin-modified GIC.

Background: Disease transmission and barrier techniques are the key concerns during ultrasonic instrumentation as this procedure has the hazard of aerosol production which has a multitude of deleterious effects on the body. The aerosol produced can affect both the patient and the clinician. The aim of this study was to assess the importance of pre-procedural rinsing before scaling by ultrasonic instrumentation and to compare the efficacy of commercially available herbal mouth rinse and a Chlorhexidine gluconate mouth rinse with a control group. The study was conducted from 1 ^st February to 15 ^th April 2012 in a tertiary referral care hospital. The study was approved by the institutional ethical committee. This was a randomized single blinded interventional study, where in 36 patients equally divided into three groups participated. Material and Methods: Thirty six patients were recruited in this study aged between 18-35 years. All patients had plaque index scores between1.5-3.0, and were categorized into three groups. Patients with systemic diseases and on antibiotic therapy were excluded. Group A or control group underwent scaling with water as pre-procedural rinse, Group B used 20 ml of 0.2% Chlorhexidine and group C were administered 18 ml of a herbal pre-procedural rinse. Aerosol splatter produced during the procedure were collected on blood agar plates and sent for microbiologic analysis for the assessment of bacterial Colony Forming Units (CFUs). The mean CFUs and standard deviation (SD) for each group were measured. Post hoc test was used to compare the differences between three groups, Control (A) Chlorhexidine (B) and Herbal (C). Results: The mean Colony Forming Units (CFUs) for control group was 114.50, Chlorhexidine group was 56.75 and herbal rinse group was 47.38. Conclusion: Pre-procedural rinsing was found to be effective in reducing aerosol contamination during ultrasonic scaling though no statistically significant difference was found between the two test groups Chlorhexidine and Herbal mouth rinse.

Background: Search for a root-end filling material fulfilling all the ideal characteristics is an ongoing process. The present study aimed to evaluate the marginal seal of the following materials when used as root-end filling materials, MTA Angelus, White ProRoot MTA, Biodentine and Glass ionomer cement (GIC). Materials and Methods: Sixty single-rooted maxillary central incisors were included in the study. The crowns were resected followed by cleaning and shaping with hand files and protaper rotary files followed by obturation of the roots. The root ends were resected at 3 mm level. Then, root-end cavity preparation of 3 mm depth was done using ultrasonic tips. The samples were randomly divided into four groups of 15 each and cavities restored with, such as (1) Group 1: MTA Angelus, (2) Group 2: ProRoot MTA, (3) Group 3: Biodentine, and (4) Group 4: GIC. The root samples were coated with two coats of nail varnish and immersed in methylene blue dye 2% for 48 h. Longitudinal root resection was done. The depth of dye penetration was evaluated under the stereomicroscope to examine the extent of microleakage. The amount of dye penetration was measured in millimeters. The results were then statistically analyzed using one-way analysis of variance and post-hoc Tukey's test. Conclusion: Microleakage was present in all the samples. Least amount of apical dye microleakage was seen in biodentine with mean value of 0.16 mm followed by ProRoot MTA 0.68 mm, MTA Angelus 0.74 mm, and GIC 1.53 mm. The best sealing ability was seen in biodentine, and this difference was statistically significant.

It was only toward the close of the last century that women emancipated themselves from their former small territory of usefulness in a strictly domestic life, and pushing forward, proved themselves often the business equal to men and sometimes their superior. If was long before this progression, when a women in business or professional ranks was almost a curiosity. When women first entered the profession, they faced many obstacles. Mentors or faculty in the dental organizations majority were male restraining women by all means. In the beginning, men were resentful because they feel women are inferior. It took a long time for women to become a consistent presence in dental schools. In the beginning, dental schools used to admit one or two women each year, later the number increased slowly. Olden day's women used to relieve not even the tooth ache but also used to relieve others fret also. But histories of dentistry were not acknowledged the talent of women whatsoever. The efforts and achievements of women punch the clock in the future dentistry. The current scenario has totally changed now. Nearly, half of all dental students' are women and 25% of them are practicing dentists. Only 3% women dentists were there before the 1970s. ^[1] Women struggled to obtain a degree, to establish practices, and are respected as professionals. Some women choose this rewarding occupation as career followed by their family members. The population tally of chosen work upbringing has changed over time. This paper reports in a delineative way of the amelioration, staggering presence, and intendment of dentistry practicing by worldwide women.

The acute-phase response (APR) is a prominent systemic reaction of the organism to local or systemic disturbances in its homeostasis caused by infection, tissue injury, trauma or surgery, or immunological disorders. The tissue macrophage is most commonly regarded as initiating the APR through direct stimulation and secretion of various cell communicating factors. Proinflammatory cytokines and mediators are significantly elevated with gingival inflammation and during the destructive phase of periodontitis. Cytokines appear to play a major role in the clinical symptoms and tissue destruction associated with progressing periodontitis. Many of these cytokines are derived from activated macrophages and can act both locally and distally to amplify cytokine production from other cell types. The host responses to periodontal disease and cardiovascular diseases were reflected by an increase in the acute-phase proteins (serum amyloid A and C-reactive protein).
