Clinical evaluation of oily calcium hydroxide suspension alone and in combination with β-tricalcium phosphate in the treatment of periodontal intrabony defects p. 70
Ankur G Shah, K Srikumar Prabhu, S Janitha
DOI:10.4103/ijmd.ijmd_27_19  
Background: An oily calcium hydroxide suspension (OCHS) has been proved to be efficient in promoting bone regeneration in periodontal intrabony defects. However, the outcome of regenerative therapy using an OCHS as an adjunct to open-flap debridement is believed to be compromised by its low consistency. Thus, the present study was carried out to evaluate an OCHS alone and in combination with β-tricalcium phosphate (β-TCP) as a bone graft material in the treatment of periodontal intrabony defects. Materials and Methods: Twenty-six intrabony defects in 10 patients were divided into experimental and control sites. The experimental sites were debrided and grafted with a combination of OCHS and β-TCP. The control sites were debrided and grafted with OCHS alone. Probing pocket depth (PPD), clinical attachment level (CAL), and gingival margin position were recorded at baseline and at 3, 6, and 9 months. Results: No differences in any of the investigated parameters were observed at the baseline between the two groups. At 9 months postoperatively, the experimental group showed a reduction in mean PPD from 7.56 ± 1.15 to 4.19 ± 1.42 mm (P < 0.001) and a change in mean CAL from 8.00 ± 1.67 to 5.06 ± 2.17 mm (P < 0.001). In the control group, the mean PPD reduced from 7.90 ± 1.10 to 5.90 ± 1.52 mm (P < 0.05) and the mean CAL changed from 8.30 ± 1.16 to 6.40 ± 1.35 mm (P < 0.05). The experimental group demonstrated significantly higher PPD reduction and CAL gain than control group. Changes in the gingival margin position were nonsignificant in both the groups. Conclusion: Overall, both therapies led to significant PPD reduction and CAL gain. The combination of an OCHS and β-TCP as a bone graft material was more effective in terms of improving clinical parameters than OCHS alone.

Manish Arun Ashtankar, Mala Baburaj Dixit, Sandeep K Pimpale
DOI:10.4103/ijmd.ijmd_29_19  
Introduction: Chronic periodontitis is one of the most prevalent diseases which affect patient's mastication and nutrition. Chronic inflammation of the gingiva also causes loss of serum albumin. Serum albumin is considered as a marker for general health as it has many functions in human body. Protein deficiency also accentuates the destructive effects of local irritants and occlusal trauma. Aims: The aim is to study the effect of surgical periodontal therapy (flap surgery) on serum albumin in chronic periodontitis patients. Subjects and Methods: Fifty participants of generalized chronic periodontitis were selected from the outpatient department. Clinical parameters were recorded at baseline, after 1 month, and 3 months. Venous blood was collected at baseline and 3 months after surgery from the participants to measure serum albumin by the bromocresol green albumin method. Statistical Analysis Used: Effect of surgical periodontal therapy on clinical parameters analyzed using one-way ANOVA (repeated-measures one-way ANOVA) followed by Tukey's multiple comparison tests for intragroup and intergroup comparison. A paired t-test was applied for serum albumin analysis. Results: Serum albumin level increased from baseline to follow-up period after surgical periodontal treatment, i.e., 3 months. This effect was found to be statistically significant (<0.001) in both groups as per the paired t-test. Conclusion: Surgical periodontal treatment (open flap debridement) has a positive effect on serum albumin level.

Nidhi Dinesh Sinha
DOI:10.4103/ijmd.ijmd_46_19  
Background: A good dimensional stability is a necessary prerequisite for successful complete denture retention and its functional efficacy. This study was conducted keeping in mind the cost factor and the need of a common man. Out of many available products, conventional heat cure resin (Dental Products of India [DPI] and Lucitone 199 [LUC]) are the standard of choice. For suitable understanding of these two products in accordance to the above-stated statement, the current study was conducted. Aim: This in vitro study was carried out to compare the dimensional stability of commercially available polymethylmethacrylate (PMMA) DPI and high-impact LUC denture base materials processed using a long curing cycle, with and without terminal boiling. Methodology: By using a chrome cobalt metal base plate, a total of forty specimens of acrylic base plates were fabricated. They consisted of two major groups of twenty specimens each, fabricated from conventional heat cure DPI and LUC heat cure resins. Each group so fabricated was further subdivided into two equal subgroups of ten specimens each, which were subjected to long curing cycle, with and without terminal boiling. The results for each group were compared by paired sample t-test for the studied objective, and data were analyzed by SPSS software version 20 (IBM Corporation, Armonk, NY USA). The level of statistical significance was fixed at the customary level ≤0.05. Results: The dimensional stability values of LUC were found superior (P < 0.05) for both curing processes as compared to DPI. Conclusion: PMMA reinforced with butadiene styrene fabricated using long curing cycle with terminal boiling showed the highest value of dimensional stability and the least was seen with conventional PMMA processed with long curing cycle without terminal boiling.

DOI:10.4103/ijmd.ijmd_47_19  
Statement of Problem: Very few studies have been conducted on the comparative evaluation of bond strength of elastomeric impression material to custom tray material using two different universal adhesive systems. Materials and Methods: A special mold was made for the fabrications of 24 samples of tray resin materials. They were divided into two main groups of 12. Perforations followed by adhesive application were done according to the grouping of samples. Polyvinyl siloxane material (medium body) was placed over the samples. A universal testing machine with a crosshead speed of 5 mm/min was used to determine the tensile bond strength of tray resin samples to medium body impression material by using different universal adhesives. Based on these values, Student's “t” test, group statistics, and ANOVA test were applied. Results: By using analysis of variance, there was no significant difference between the strength of bonding of tray resin material and medium body addition silicone by different adhesive systems. Conclusion: It was concluded that Medicept Universal tray adhesive system is as good as 3M™ universal tray adhesive system to achieve a good bond between tray resin and medium body addition silicone.

Knowledge, awareness, and practices in relation to potentially malignant disorders of the oral cavity in a rural area of Western Maharashtra, India p. 100
Kshipra Chandrakant Deshpande, Sanmay Parakh, Kiran Jadhav
DOI:10.4103/ijmd.ijmd_58_19  
Background: It has been well established by researchers that virtually all oral cancers are preceded by visible clinical changes in the oral mucosa mostly in the form of white or red patch. The prevention and early detection of such potentially malignant disorders (PMDs) have the potential of not only decreasing the incidence but also in improving the survival of those who develop oral cancer. The lack of knowledge and awareness of public about the signs, symptoms, and risk factors is responsible for the diagnostic delay in identifying the PMDs. This study aimed to evaluate the knowledge, awareness, and practices in relation to the early detection of PMDs. Materials and Methods: It was a cross-sectional, community-based survey where 600 participants were enrolled in the study. A semi-structured preset, pretested questionnaire was used to elicit information about tobacco-associated oral habits, their knowledge and awareness toward PMDs, and to elicit information regarding practices in relation to these deleterious oral effects. The results obtained were statistically analyzed using the SPSS (version 11) software and Chi-square test. Results: This study showed that there is a lack of knowledge and awareness about the early signs and common symptoms of PMDs. The level of knowledge and awareness was directly proportional to the education level, whereas it was inversely proportional to the prevalence of risk habit. Conclusion: Lack of knowledge and awareness of early signs of oral cancer and oral PMDs was observed in studied population. As their general awareness about oral cancer and oral PMDs was good, a redirection of focus is warranted toward implementing intensive oral health education programs for the recognition of risk habits, warning signs of PMDs, and early detection of oral cancer.

DOI:10.4103/ijmd.ijmd_1_20  
Background: India has the highest usage of smoked and smokeless tobacco around the globe. Various studies already showed that when smoking and chewing tobacco used together, it increases the risk for developing various cancerous and precancerous lesions in the oral cavity. Context: The study was conducted among the population of Kolkata and the surrounding districts in West Bengal, India. Aim: This study aimed to know the prevalence of cancer-causing habits and to find their pattern of use as well as to assess the prevalence of oral mucosal changes due to the use of these habit products(Tobacco in any form,arqqecanut and Alcohol). Materials and Methods: Three hundred and seventy-four individuals aged 15 years and above were selected. Face-to-face interview was conducted using structured questionnaire. The data were summarized, and statistical analysis was done. Statistical Analysis: Percentage calculation was done. Results: About 42.24% of individuals (33.15% men and 9.09% women) above 15 years of age have any one or more than one cancer-causing habit. Among the study population, smoking was 26.20%, chewing was 20.32%, and drinking was 13.36%. The most prevalent oral lesion was leukoplakia (3.2%). Conclusion: The study of this nature could help clinicians, researchers, and policy makers to identify their target population.

Isolated postinflammatory perioral hyperpigmentation: A rare case report p. 115
Tibin K Baby
DOI:10.4103/ijmd.ijmd_28_19  
Postinflammatory hyperpigmentation (PIH) is an acquired hypermelanosis occurring after cutaneous inflammation or injury that can affect all skin types but more in dark-skinned patients. Etiologies for facial PIH include infections, allergic reactions, papulosquamous diseases such as psoriasis or lichen planus, medication-induced hypersensitivity reactions, and cutaneous injury from irritants, burns, or cosmetic procedures. PIH results from the melanocyte's response to the cutaneous insult causing increased production and/or redistribution of melanin. Literature search could show that this is the first case report on isolated acute perioral PIH following perioral contact dermatitis.

Jessica Paola Flor Calero, Danielle Gregorio, Elcia Maria Varize Silveira, Luciana Prado Maia
DOI:10.4103/ijmd.ijmd_55_19  
Gingival recessions (GRs) in anterior teeth are the most common complaint of patients for disharmony in the smile. The objective is to show a clinical case of GR treatment by the tunnel technique associated with subepithelial connective tissue graft (SCTG). We report a patient of 56-year-old, female, frequents specialization clinic of periodontics to treat Miller's Class I GR of 11 and 21 teeth. It was used tunnel technique because it does not result in scarring. This technique was associated with SCTG to guarantee increase the gingival thickness. After 14 days, the gingival margin was over the cemento-enamel junction with esthetic harmony. The position stability was maintained for 90 and 180 days. It is possible to conclude that a modified tunnel technique can be considered as a treatment of multiple GR on esthetic area.

Balasubramaniam Anuradha, Rajendran Devakar, Jagadeesan Aarthi, Suresh Mitthra
DOI:10.4103/ijmd.ijmd_59_19  
The composition of smile architecture includes pink gingiva and white tooth structure which gives an esthetic appearance. As age advances, gingival recession is seen which contributes to dentinal hypersensitivity and unsightly smile esthetics. Due to this, increasing number of patients are seeking dentists for the absence of pink-colored gingiva. Pink composites are gingival-colored composites that help to create a life-like tooth easily by reconstructing the red-white boundary with superior esthetics. This material provides long-lasting, high esthetic restorations with low abrasive values and high compressive and transverse strength. This shares a case report on how pink composites help in reconstructing the red-white boundary.
