AIM: To assess the knowledge and awareness of nurses in handling maxillofacial injuries. METHOD: A cross-sectional questionnaire study was conducted among the staff nurses of the multi-specialty Gokul Newtech Hospital, Jamnagar, Gujarat. Forty nursing staff were included in the study. Kruskal-Wallis ANOVA, Spearman's correlation and Mann-Whitney U tests were applied for statistical analysis. RESULT: There was no statistically significant difference between the mean knowledge score concerning the study participant's age, work experience, and education. According to the survey, a majority of the nurses either did not know the answer or answered incorrectly. CONCLUSION: It can be concluded that there is a requirement of new guidelines and recommendations in the existing teaching and training modules being followed by the nursing schools across the country.

Techniques to Evaluate Dental Erosion: A Systematic Review of Literature.

This article reviews different techniques for evaluating dental erosion, weighs the advantages and disadvantages of these techniques, and presents the latest trends in the study of dental erosion. In May 2014, an initial search was carried out in the PubMed/MEDLINE database of indexed journals from 1975 to 2013 using the following keywords: dental erosion; dental erosion In-vitro; and dental erosion in-vivo. Bibliographic citations from the papers found were then used to find other useful sources. The authors categorize the techniques into three classes: in-vitro, in-vivo and in-vitro/in-vivo. The article discusses the instrumentation required to use each of these techniques, as well as their rationale, merits and applications. The emergence of in-vitro/in-vivo techniques offers the potential to accurately quantify tooth wear in clinical situations. Cross-sectional as well as longitudinal studies show that these techniques will improve diagnosis, treatment planning and management of dental erosion.

Comparative Evaluation of Antimicrobial Activity of Pomegranate-Containing Mouthwash Against Oral-Biofilm Forming Organisms: An Invitro Microbial Study.

INTRODUCTION: Pomegranate is considered "A pharmacy unto itself". Hydrolysable tannins called punicalagins which have free scavenging properties are the most abundant polyphenols found in pomegranate-containing mouthwash. AIM: To evaluate antimicrobial effect of pomegranate- containing mouthwash on oral biofilm-forming bacteria. MATERIALS AND METHODS: The mouthwashes used were divided into three groups- Group A: Chlorhexidine mouthwash (Hexidine); Group B: Herbal Mouthwash (Hiora) and Group C: Pomegranate-containing Mouthwash (Life-extension). Each mouthwash was diluted to five different concentrations. Reference strains of Streptococcus mutans (S.mutans) (ATCC 25175), Streptococcus salivarius (S.salivarius) (ATCC 7073), and Aggregatibacter actinomycetemcomitans (A.a) (NCTC 9710) were selected as being colonizers in dental biofilm formation. On each culture plate, five wells of 5mm were prepared and mouthwashes with different concentrations were added, followed by incubation in a CO2 jar for 24 hours at 37°C. Inhibition zone diameters were measured using a digital caliper. RESULTS: Chlorhexidine (0.12%) presented a zone of inhibition between 38.46% to 96.15% for all the three organisms, while Hiora presented zone of inhibition ranging from 33.33% to 69.23% but was resistant at <10 ml of dilution. Pomegranate mouthwash presented a zone of inhibition ranging from 38.48 to 57.69%, but was resistant at <10ml for S.mutans, and <25ml for A.a and S.salivarius. ANOVA test was done to compare the dilution of mouthwashes for a particular organism and Tukey's multiple comparison tests were done to find the exact difference. A significant difference was seen between all the three groups at 50ml and 75 ml of dilution. At 75 ml concentration, a statistical difference was found between Groups B & C and Groups A & B; and at 50 ml between Groups A&C. CONCLUSION: All the three types of mouthwash exhibit anti-microbial activity against biofilm forming organisms but at varying concentrations. Although Chlorhexidine still continues to be the gold standard, pomegranate-containing or herbal mouthwashes can be easily substituted for long term use, avoiding the side effects of chlorhexidine.

Quantitative Assessment of Tumor Associated Macrophages in Head and Neck Squamous Cell Carcinoma Using CD68 Marker: An Immunohistochemical Study.

INTRODUCTION: Oral Squamous Cell Carcinoma (OSCC) is one of the most prevalent cancers in India. Clear evidence regarding inflammation being an etiological factor of cancer was found only in the last few decades. A major inflammatory component in the tumor tissue is Tumor-Associated Macrophages (TAMs). The CD68 antibody is a marker for staining TAMs. AIM: The aim of this study is to quantify the macrophage count in healthy oral mucosa and OSCC and comparing TAMs in different histopathological grades of OSCC immunohistochemically. MATERIALS AND METHODS: Thirty archival specimens of OSCC patients and 10 healthy biopsy samples were collected. Immunohistochemical staining was done using a CD68 marker. Statistical analysis was done using Kruskal-Wallis ANOVA and Mann-Whitney U test. RESULTS: Comparing CD68 expression in various study groups showed a significant difference (p=0.000). The pair-wise analysis showed different grades of OSCC, which differed significantly for CD68 expression from the normal oral mucosa. CONCLUSION: The most significant cells present in tumor stroma are TAMs, which remain in close proximity to neoplastic cells and interact with them via several chemical mediators, which may serve to increase the invasiveness of the malignant epithelium. Dense infiltration of TAMs adjacent to tumor cells and islands vividly implies their role in tumor progression.

To Splint or Not to Splint: The Current Status of Periodontal Splinting.

Loss of tooth-supporting structures results in tooth mobility. Increased tooth mobility adversely affects function, aesthetics, and the patient's comfort. Splints are used to over-come all these problems. When faced with the dilemma of how to manage periodontally compromised teeth, splinting of mobile teeth to stronger adjacent teeth is a viable option. This prolongs the life expectancy of loose teeth, gives stability for the periodontium to reattach, and improves comfort, function and aesthetics. Although splinting has been used since ancient times, it has been a topic of controversy because of its ill effects on oral health, including poor oral hygiene and adverse effects on supporting teeth. There have been considerable advancements in the materials used for splinting, resulting in fewer ill effects. This article is intended to provide the clinicians with an updated overview of splinting, types and classification of splints, with their indications, contraindications,rationale and effects on oral health.

Dental knowledge and awareness among grandparents.

AIM: To investigate grandparent's knowledge and awareness about the oral health of their grandchildren. METHODS: Grandparents accompanying patients aged 4-8 years, who were living with their grandchildren and caring for them for a major part of the day, when both their parents were at work were included in the study. A 20-item questionnaire covering socio-demographic characteristics, dietary and oral hygiene practices was distributed to them. The sample comprised of 200 grandparents (59 males, 141 females). χ(2) analysis and Gamma test of symmetrical measures were applied to assess responses across respondent gender and level of education. RESULTS: Oral health related awareness was found to be low among grandparents. In most questions asked, grandparents with a higher level of education exhibited a better knowledge about children's oral health. Level of awareness was not related to their gender. CONCLUSION: Oral hygiene and dietary habits are established during childhood. There is a great need for dental education of grandparents as they serve as role models for young children.

Comparative Evaluation of Coronally Advanced Flap with and without Bioactive Glass Putty in the Management of Gingival Recession Defects: A Randomized Controlled Clinical Trial.

BACKGROUND: The need-of-the-hour is a material that can support coronally advanced flap (CAF) procedures in treatment of gingival recession. Recent literature shows that various bone substitutes are being used for this procedure. This study clinically evaluates the outcomes of CAF with and without bioactive glass putty (NovaBone®) in terms of root coverage, gains in keratinized tissue height, and root coverage esthetic score in multiple gingival recession defects. METHODS: Ten healthy patients (age range 18-45 years) with multiple bilateral (n = 40 test 20; control 20) and comparable Miller's Class I or Class II gingival recession defects were selected. The defects were randomly assigned by a computer-generated list to either test (CAF + bioactive glass putty) or control (CAF alone) groups. Clinical parameters included gingival recession (GR), probing pocket depth (PPD), clinical attachment level (CAL), keratinized tissue height (KTH), root coverage esthetic score (RES) evaluated at baseline and at 6 months post-surgery CAF with or without bioactive glass putty. RESULTS: Six months post-surgery all clinical parameters showed significant reductions. Gingival recession showed significant reduction both in test and control groups (2.0 ± 0.47 mm and 2.3 ± 0.48 mm, respectively; p < 0.05) with no intergroup difference. The exposed root was covered by 72% (test) and 79% (control). CAL gain was also significant in both groups (test: 2.7 ± 0.67 mm; control: 2.8 ± 0.78 mm; p < 0.05) with no intergroup difference. Keratinized tissue height gain was significant in both the groups (test group: 1.2 ± 0.42 mm; control group: 0.9 ± 0.57 mm) with no intergroup difference. Also, the RES was significant for both the test and control groups (7.2 ± 2.78 and 7.7 ± 1.41 respectively) with no intergroup differences. CONCLUSIONS: In isolated Class I/II GR defects, CAF associated with bioactive glass putty provided no significant difference in root coverage, CAL, KTH or RES compared to CAF alone. However, statistically significant gains were seen in all the parameters in both groups as compared to baseline. We refute the claims of the recent studies using a bone substitute for root coverage. Further long-term clinical trials are warranted to substantiate our results.

Evaluation of efficacy of a novel resorbable collagen membrane for root coverage of Miller's Class I and Class II recession in the maxillary anteriors and premolars.

BACKGROUND: There are several surgical techniques in literature that have been used to perform root coverage (RC). Currently, the use of a resorbable collagen membrane (RCM) as a guided tissue regenerative material is one of the highly sought treatment modalities. The present study aimed at evaluating the clinical outcome of RC in the treatment of Miller's Class I and II recession defects in maxillary anteriors and premolars by coronally advanced flap (CAF) with and without RCM. MATERIALS AND METHODS: This split-mouth study (bilateral buccal recession defects) was randomized to include 15 test (CAF + membrane) and 15 control (CAF alone) sites. Clinical parameters included gingival recession depth (RD), probing pocket depth (PPD), clinical attachment level (CAL), and keratinized tissue height (KTH) measured at baseline and 9 months postoperatively. RESULTS: Both test and control groups showed statistically significant (P < 0.05) reductions in RD (1.54 ± 0.46 mm and 1.60 ± 0.07 mm), PPD (0.53 ± 0.15 mm and 0.94 ± 0.10 mm), increase in KTH (0.67 ± 0.90 mm and 0.73 ± 0.14 mm) and CAL (1.94 ± 0.27 mm and 2.60 ± 0.19 mm) when comparing the 9-month data from baseline. The present study showed that mean improvement in RD was 1.60 ± 0.507 and 1.53 ± 0.64 mm in both test and control groups, respectively. Mean percent RC was 58.33% ±12.19% and 56.22% ±10.22% for test and control groups, respectively. However, there were no statistically significant differences between groups for RD, PPD, KTH, and CAL. CONCLUSION: The results of this study suggest that both the groups CAF (control) and CAF and RCM (test) could be successfully used to treat Miller's Class I and II gingival recession defects and also demonstrated an overall significant improvement in all the assessed clinical parameters. However, there was a greater reduction of gingival RD with the use of RCM when compared with the group of CAF alone.

Dietary antioxidants and their indispensable role in periodontal health.

Periodontitis is an increasing area of interest due to its global prevalence. This inflammatory condition results due to the loss of the critical balance between the virulence factors produced by microorganisms and the inflammatory host response. A number of efforts have been made in the past to address this condition and regain periodontal health. Targeting the root cause by nonsurgical debridement has been considered the gold standard. However, research has shown the possible effects of nutrient deficiency and an imbalanced diet on the periodontium. Therefore, an effort toward the maintenance of optimal conditions as well as improvement of the oral health necessities the introduction of adjunctive nutritional therapy, which can benefit the patients. Antioxidants in the diet have some remarkable benefits and valuable properties that play an irreplaceable role in the maintenance of periodontal health. These have emerged as excellent adjuncts that can enhance the outcomes of conventional periodontal therapy. The aim of this review article is to highlight some of these dietary antioxidants that can make a notable difference by striking a balance between health and disease.

Dynamic role of myofibroblasts in oral lesions.

Fibroblasts are the most abundant cellular components of connective tissue. They possess phenotypical heterogenicity and may be present in the form of smooth muscle cells or myofibroblasts (MFs). MFs are spindle-shaped cells with stress fibres and well-developed fibronexus, and they display α-smooth muscle actin immunohistochemically and smooth-muscle myofilaments ultrastructurally. MFs play a crucial role in physiological and pathological processes. Derived from various sources, they play pivotal roles not only by synthesizing and producing extracellular matrix components, such as other connective tissue cells, but also are involved in force production. In the tissue remodelling phase of wound closure, integrin-mediated interactions between MFs and type I collagen result in scar tissue formation. The tumour stroma in oral cancer actively recruits various cell types into the tumour mass, where they act as different sources of MFs. This article reviews the importance of MFs and its role in pathological processes such as wound healing, odontogenic cysts and tumours, salivary gland tumours, oral preneoplasia, and oral squamous cell carcinoma. Research oriented on blocking the transdifferentiation of fibroblasts into MFs can facilitate the development of noninvasive therapeutic strategies for the treatment of fibrosis and/or cancer.

Anti-carcinogenic and Anti-bacterial Properties of Selected Spices: Implications in Oral Health.

"Let food be thy medicine and medicine be thy food", as said by the father of medicine, Hippocrates in 431 B.C. Nature has provided us with a variety of treatment modalities in the form of food. For the first 5,000 years of civilization, humans relied on herbs and foods for medicine. Only in the past 60 years have we forgotten our medicinal "roots" in favor of patented medicines. While pharmaceutical ingredients have their value, we should not overlook the well-documented, non-toxic and inexpensive healing properties of food. As an individual we consume food several times a day without a complete understanding of its innate qualities. As part of a daily diet, food plays a significant role in helping our bodies function at their best. There are hundreds of extremely nutritious foods, but the items in this article do more than providing healthy nutrients. Many of them consist of ingredients with hidden pharmaceutical qualities ranging from anti-inflammatory to anti-carcinogenic agent. They not only boost our innate immunity but also act as an adjunct to medicines for specific treatment. Prevention and management of symptoms can often be improved significantly through the foods we consume regularly. This paper overviews these beneficial traits of food ingredients, consumed on a daily basis, in various oral diseases.

Association of Postmenopausal Osteoporosis and Periodontal Disease: A Double-Blind Case-Control Study.

BACKGROUND: Both osteoporosis (OP) and periodontitis are chronic inflammatory diseases associated with bone loss mediated by local and systemic factors. The two diseases share common risk factors. Previous studies have suggested that OP in itself is a predisposing factor for periodontal tissue destruction in postmenopausal women. However, only a moderate correlation has been shown between the two conditions. In this study, we compared the severity of periodontal disease in postmenopausal osteoporotic women and postmenopausal women without OP. MATERIALS AND METHODS: The study group consisted of 100 postmenopausal women in the age group of 50-65 years: Group 1 (50 osteoporotic) and Group 2 (50 non-osteoporotic women). Periodontal parameters included sulcus bleeding index, oral hygiene index simplified, probing pocket depth (PPD), and clinical attachment loss (CAL), interproximal alveolar bone loss (ABL), and number of missing teeth. The correlation of periodontal disease status with systemic bone mineral density (BMD) was evaluated by dual-energy X-ray absorptiometry. RESULTS: The results indicated that osteoporotic (Group 1) women had a significantly greater PPD, CAL, and ABL when compared with the non-osteoporotic Group 2 (P < 0.0001). There was no significant correlation between BMD and various parameters between the groups. CONCLUSIONS: Within the limitations of the present study it was noted that postmenopausal OP is associated with an increased incidence and severity of periodontal disease. Educating postmenopausal osteoporotic women regarding the importance of good oral care should be part of their management regime. Hence, it could be inferred a possibility of a probable relationship between OP and periodontal disease, but long-term prospective studies are warranted in the future in order to provide definitive evidence.

Malignant melanoma of gingiva: Report of a rare case.

According to the World Health Organization, oral malignant melanoma (OMM) is a rare disease, accounting for only 0.8% of all melanomas, 8% of head and neck melanomas, and up to 0.5% of all oral malignancies. OMM presents as a pigmented lesion with asymmetrical borders, irregular surface characteristics, and a distinct color. Melanoma-associated pigmented lesion of the oral cavity does not possess clinical specificity and frequently divert the clinical diagnosis; hence, differential diagnosis becomes mandatory. Furthermore, the unpredictable pathophysiological behavior and delayed detection, contributes for poor prognosis of the disease. As a result, the 5 years survival rate is only 10-25%. Commonly OMM is seen in maxillary gingiva of males. However, we report a rare case of a middle-aged female having pigmentations and growth over mandibular gingiva.

Comparative evaluation of platelet-rich fibrin biomaterial and open flap debridement in the treatment of two and three wall intrabony defects.

BACKGROUND: Platelet-rich concentrates are the most widely used regenerative biomaterials. Stimulation and acceleration of soft and hard tissue healing are due to local and continuous delivery of growth factors and proteins, mimicking the needs of the physiological wound healing and reparative tissue processes. This article aims to evaluate the clinical efficacy of open flap debridement (OFD) with or without platelet-rich fibrin (PRF) in the treatment of intrabony defects. MATERIALS AND METHODS: Twenty subjects with forty intrabony defects were treated with either autologous PRF with open-flap debridement (test, n = 20) or open-flap debridement alone (control, n = 20). Soft tissue parameters included: Plaque index, sulcus bleeding index, probing depth, relative attachment level and gingival marginal level (GML). The hard tissue parameters included-distances from: Cement enamel junction to the base of the defect (CEJ-BOD): Alveolar crest to the base of the defect (AC-BOD): And CEJ to AC. The parameters were recorded at baseline and at 9 months postoperatively calculated using standardized radiographs by image-analysis software. RESULTS: Statistically significant (0.005*) intragroup improvements were seen with all the hard and soft parameters in both test and control groups, except for GML. Statistically significant improvements were seen with the mean defect fill (CEJ-BOD and AC-BOD) (P = 0.003*) when intergroup comparisons were made. CONCLUSIONS: Adjunctive use of PRF with OFD significantly improves defect fill when compared to OFD alone. PRF has consistently been showing regenerative potential; it is simple, easy and inexpensive biomaterial compared with bone grafts.

The effect of alloplastic bone graft and absorbable gelatin sponge in prevention of periodontal defects on the distal aspect of mandibular second molars, after surgical removal of impacted mandibular third molar: a comparative prospective study.

AIM: Recent studies claim that haemostatic agents can be used as bone graft substitutes. The aim of this study was to compare the efficacy of alloplastic bone graft with absorbable gelatin sponge in prevention of periodontal defects distal to mandibular second molar after the surgical removal of impacted mandibular third molars. MATERIALS AND METHODS: A prospective, randomized, single-blind split-mouth study was designed. The study consisted of 25 patients requiring surgical removal of bilateral impacted mandibular 3rd molars. The surgical sites were randomly divided into 2 groups: group I: G-graft (hydroxyapatite + collagen, study group) and group II: Abgel (absorbable gelatin sponge, control group). Patients were recalled on lst and 7th postoperative days and 3rd and 6th postoperative months. Probing depth, alveolar bone levels and soft tissue wound healing were evaluated. Paired t test was used to compare pre and post-operative alveolar bone levels and probing depth (PD). Wilcoxon signed ranks test was used to compare the wound healing. RESULTS: The soft tissue wound healing, PD and the distance between the cemento-enamel junction on the distal aspect of mandibular second molar (point A) and the alveolar crest on the distal aspect of the same tooth (point B) were significantly higher in group I as compared to group II. CONCLUSION: This study reveals an increase in the alveolar bone level, improvement of PD and better wound healing in group I. Group II subjects required longer healing time than the normal. The authors disagree the claim that the haemostatic agents can be used as bone graft substitutes. However, long-term, multicenter, randomized controlled clinical trials are required.

To pack or not to pack: the current status of periodontal dressings.

Surgical wound dressings have been employed over several centuries for the purpose of protection of surgical sites, to prevent postoperative infection and to accelerate healing. Periodontal dressings, also known as periodontal packs, provide similar benefits when applied after periodontal surgical procedures. They can broadly be categorized as eugenol-based dressings and noneugenol dressings. Over the years, many modifications have been made to the composition of such dressings to improve their physical and therapeutic properties. Controversies surrounding the rationale for their use, advantages and disadvantages of the most commonly employed periodontal dressings and their current status in clinical practice are described in this comprehensive review. From the evidence-based literature presented here, we have also attempted to answer the question of whether there is a universal need for the application of periodontal dressings.

Complete oral rehabilitation in a case with severe dental fluorosis.

The authors have presented a technique of full occlusal rehabilitation in a case of severe dental fluorosis. In this technique, maxillary and mandibular anterior teeth were simultaneously prepared and restored first. This was followed by simultaneous preparation of maxillary and mandibular posterior teeth that were restored in canine guided occlusion. The technique and sequence followed here is unique and is not available in dental literature. This technique reduces number of appointments while fulfilling all objectives. Periodontal follow-up over 3 years was satisfactory. A restorative treatment protocol has been devised for fluorosis which will act as a guide for the dental practitioners.

Comparison of 4% articaine and 0.5% bupivacaine anesthetic efficacy in orthodontic extractions: prospective, randomized crossover study.

AIM: Articaine and bupivacaine are both amide-type local anesthetic (LA) agents, of almost equal potency. However, lidocaine is considered the gold standard and is the most widely used anesthetic agent because of its potency, safety, and efficiency. Articaine is fast acting and bupivacaine is a long-lasting LA. The aim of this randomized controlled crossover clinical study was to evaluate and compare the clinical anesthetic efficacy of 4% articaine and 0.5% bupivacaine in orthodontic extractions models. METHODS: Forty systemically healthy patients (age range: 10-18 years), requiring premolar extraction for orthodontic reasons (all 4 premolars) were included. Patients were categorized into two groups (4% articaine and 0.5% bupivacaine) in a crossover manner (160 premolars). Parameters recorded included: time of anesthetic onset, duration of postoperative analgesia, time to first rescue analgesic medication, and visual analog scale (VAS). At the first appointment, both upper and lower premolars were extracted on one side of the jaws (right or left). A fixed volume of 1.4 mL of 4% articaine or 0.5% bupivacaine (based on a computer-generated list) was infiltrated in the buccal vestibule (local infiltration) for extraction. At the second appointment, after a washout period of 15 days, the anesthetic agent that was not administered at the first appointment was administered in a crossover manner. Each patient was evaluated using a 100-mm VAS during and after extraction. RESULTS: The results showed that 4% articaine had significantly faster onset of action and lower VAS scores when compared with bupivacaine. However, the duration of analgesia and time to first rescue analgesic medication was longer in the bupivacaine group. CONCLUSION: Articaine seemed to have better potency and efficacy in terms of onset of action and lower pain scores compared to the bupivacaine group. Further studies are required to confirm these results.
