Assessment of Bite Forces in Restored Teeth with Different Commonly Used Restorative Materials: A Comparative Study

ABSTRACT Objective: To evaluate and compare bite force (BF) in permanent first molars restored with glass ionomer cement (GIC), composite and amalgam, and normal contralateral permanent first molars. Material and Methods: BF was recorded in decayed permanent first molars, which were filled with GIC (n=30), composite (n=30), and amalgam (n=30), and in healthy contralateral first molars (n=90) with Force Transducer Occlusal Force Meter and compared. Results: BF was significantly higher in normal teeth on the contralateral side compared to teeth restored with GIC and composite. However, in patients with amalgam restoration, though it was less compared to that on the contralateral side, it was not statistically significant (p>0.05). Conclusion: Restoring teeth with various filling materials may improve bite force. In the present study, it was found that the teeth restored with amalgam had higher bite forces in comparison to the other restorative materials used. However, it was not comparable to that observed in the normal tooth (control) on the contralateral side.

Knowledge, Attitude and Practices Regarding Consumption of Carbonated Soft Drinks Among the Dental Students: A Cross-Sectional Study

Abstract Objective: To assess and evaluate the knowledge, attitude, and practices regarding the consumption of carbonated drinks among dental students. Carbonated drinks are pervaded by carbon dioxide and have more adverse effects since they are acidic in nature. Nowadays, these are consumed more widely globally, causing many systemic diseases; diabetes and obesity are common. Material and Methods: This study includes 204 individuals belonging to the age group of 18-26 years. A self-structured objective type cross-sectional questionnaire survey was conducted to assess the knowledge, attitude, and practice of dental students regarding carbonated drinks. The participants were instructed to mark the most appropriate correct answer from the given list of close-ended type questions. Results: Of 204 dental students, the study population includes 125 female and 79 male students. 98.5% of the students knew about carbonated drinks, while 1.5% were unaware. Conclusion: Most participants preferred to have carbonated drinks even with their awareness about the ill effects of these drinks. Possible implications by the government authorities may probably increase awareness among the population (AU).

Efficacy of laser photobiomodulation pulpotomy in human primary teeth A randomized controlled trial

Background: Laser photobiomodulation (LPBM), also called Low Level Laser Therapy (LLLT), has shown potential to reduce the pulpal inflammation and to preserve the dental pulp vitality, thereby improving healing. Lasers being minimally invasive, safe, and patient friendly prompt its application in pediatric dentistry. Aim: The aim of this study was to evaluate and compare the clinical and radiographic success rates of LPBM and formocresol pulpotomy at 9 months post intervention in human primary molars. Materials and Methods: A randomized controlled, split-mouth study design was followed involving children aged 4–7 years with at least two primary molars indicated for pulpotomy. Sixty-eight eligible primary molars were randomly allocated to two interventions – formocresol pulpotomy (Group I) and LPBM pulpotomy (Group II). Statistical Analyses: Chi-square test was used for statistical analysis fixing significance level at P ? 0.05. Results: There was no statistically significant difference in the clinical success rates between the formocresol group (97.05%) and the photobiomodulation group (94.1%) (?2 = 0.34, P = 0.55); however, the radiographic success rate was significantly high in the laser group (94.1%) compared to the formocresol group (58.82%) (?2 = 11.76, P = 0.001). Conclusion: LPBM could be a viable nonpharmaceutical alternative for formocresol pulpotomy in human primary teeth

In silico and in vitro cytotoxicity profile of hydroalcoholic extract/ fraction(s) of Pachygone ovata

Medicinal plants have been used in the past for the treatment of diseases and continue to be an important reservoirfor the development of new drugs. With the increasing burden of cancer globally, there is a need to find neweranticancer agents. The process of identification and evaluation of cytotoxic molecules from plants can be achievedconveniently by using simple yet reliable screening models and combining with in silico techniques. Pachygone ovata,least explored plant from Menispermaceae family, is known to be rich in alkaloids. This study aimed to identify thecytotoxic constituents from Pachygone ovata through bioactivity-guided fractionation using Brine shrimp lethalitybioassay as a screening model. The active fraction in this assay was evaluated for its in vitro cytotoxic activity onhuman tumor cell lines. Some reported alkaloids were studied for their binding affinities with topoisomerase II bymolecular docking. The study revealed the cytotoxic constituents from P. ovata. The study also revealed alkaloids withhigher binding affinity with topoisomerase II, and the scope for further use leads to the development of new drugs.

Challenges of Autism Spectrum Disorders Families Towards Oral Health Care in Kingdom of Saudi Arabia

Abstract Objective: To assess the knowledge, attitudes, and practice regarding oral health care among parents of autistic children and also the challenges faced by them in providing dental care for their Autism Spectrum Disorders (ASD) children's in four regions of Kingdom of Saudi Arabia. Material and Methods: In total, 263 parents of autistic children participated in this cross-sectional study who were enrolled from 4 major regions of Kingdom of Saudi Arabia. A self-administered questionnaire formulated in simple Arabic was distributed to parents of children diagnosed with autism or any form of ASD. The questionnaires consisted of demographic questions and also to assess their knowledge on oral health, child's oral hygiene practices and visits to their dentist, oral hygiene, experience and challenges in waiting room area before the dental treatment, acceptance of treatment or rejection, accessibility to find non-dental centers either government or private for treatment and their recommendations. Results: All the parents brushed their child's teeth using a toothbrush and fluoridated toothpaste. A total of 29.7% of the parents informed that their child never brushes teeth. A total of 41.4% of the parents visit the dental clinic when the child complains about dental problems and 54% find difficulty in locating appropriate dental clinic to deal with their ASD children. Most parents reported taking their child to a private office (38.8%). Only 3.8% of parents reported that their children had seizures during dental procedures. Conclusion: The knowledge toward oral health was found to be inadequate among the majority of the parents. Parents of ASD children need to be educated about the consequences of oral health neglect and the importance of regular check-ups.

Oral Health-Related Quality of Life (OHRQoL) in Patients with Dental Prosthesis

Abstract Objective: To determine the Oral Health-Related Quality of Life (OHRQoL) for post-treated fixed dental prostheses in selected sample of patients. Material and Methods: 120 patients treated with fixed dental prostheses, either single crowns or fixed partial dentures in maxillary or mandibular arches were asked to express their views about their quality of life. Patients' files were randomly selected from the archives of Department of Prosthetic Dental Sciences, College of Dentistry, Jouf University, Saudi Arabia. For this purpose, a self-structured questionnaire was prepared and their responses recorded. The responses were categorized on a 5 point scale and frequencies calculated. Results: Of 120 patients approached, 79 responded with the mean age group of 37 years. From the survey, it was noted that only three variables were statistically significant, those relating to the importance of natural teeth over fixed prostheses (p=0.046), the ability to chew all kinds of foods (p=0.021) and satisfaction with the occlusion (p<0.001). Conclusion: Oral health remains important, which directly or indirectly is related to many systemic diseases. In the present study, the majority of patients were satisfied with the treatment given.

Clinical outcomes after percutaneous coronary intervention in patients with coronary artery disease: six months results from a single centre study

Background: The study aimed to evaluate clinical outcomes in patients with coronary artery diseases (CAD) who underwent percutaneous coronary intervention (PCI), to identify the factors associated with clinical outcomes and survival among such patients, to explore the procedure related complications, and to assess restenosis and stent thrombosis rates following PCI.Methods: This retrospective, single-center, observational study was conducted at a tertiary-care center in India, which included patients with CAD undergoing PCI from January 2016 to December 2016. Angiographic and clinical success and complications related to both procedural and vascular access were noted. Patient were followed-up for clinical outcomes up to 6-months. Primary outcome of the study was all-cause mortality. Secondary outcome measures were cardiovascular mortality, and event free survival, angina, cardiovascular events and restenosis and stent thrombosis.Results: A total of 831 patients were included of which majority were males (83.5%). Smoking was found in 33.7%, diabetes in 35.6%, and hypertension in 37.7%. At 6-months, follow-up was obtained for 711 patients. The clinical composite endpoint seen in 9.8% of patients. Angina (13.2%), acute coronary syndrome (3.1%), stent thrombosis (1.0%), in-stent restenosis (3.9%), cardiovascular and all-cause mortality (2.7%), heart failure (7.3%) and stroke (1.7%) were reported at 6-months follow-up.Conclusions: The PCI in a tertiary-care centre leads to low rates of periprocedural events and low rates of clinical outcomes at 6-months follow-up. Moreover, left ventricular ejection fraction was shown to be major predictor for cardiovascular mortality in post-PCI patients. Hypertension was significantly associated with stroke post-PCI.

A Study of Prevalence of Microalbuminuria and Diabetic Retinopathy in Rural Patients Presenting to a Tertiary Care Hospital in North India

Introduction: Diabetic nephropathy is the leading causeof End Stage Renal Disease in the world, accounting formore than one third of the cases. Micro albuminuria isa marker of wide spread micro vascular damage in Type 2Diabetes Mellitus and an earliest marker for nephropathy.The correlation between presence of overt proteinuria andproliferative diabetic retinopathy have been demonstrated inboth Type 1 and Type 2 diabetic patients. There is an increasingevidence that micro albuminuria could be used as a marker forearly diabetic retinopathy. However, this relationship has notbeen established in our setting. Hence, we planned to evaluatethe prevalence as well as correlation of micro albuminuria andretinopathy in patients of Type 2 Diabetes Mellitus.Material and Methods: 100 Type 2 diabetic patients willingto participate, were enrolled in the study after due approvalfrom the Institutional Ethical committee. Prevalence of microalbuminuria was checked using Micral test. Body Mass Indexand Glycosylated Hemoglobin were also measured. Patientswere evaluated by direct and indirect ophthalmoscopy to lookfor evidence of retinopathy.Results: 56% patients were male with majority of them(70%) were in the age group of 40-60 years. In 39%patients, duration of diabetes was less that 5 years and equalpercentage of patients had micro albuminuria. 45% patientsshowed signs of diabetic retinopathy, whereas, both microalbuminuria and retinopathy were observed in 32% ofpatients (p <0.001). Compared to overall prevalence of microalbuminuria and retinopathy, patients with age more than50 years showed higher prevalence of 51.61% and 56.45%(p=0.001) respectively. Micro albuminuria (52.45%) anddiabetic retinopathy (57.37%) were more likely with durationof diabetes above 6 years (p=0.001). Other factors whichwere statistically significant were Glycosylated Hemoglobin(HbA1c) more than 7% and Body Mass Index (BMI) >25kg/m2.Conclusion: The study showed that there is significantcorrelation between the presence of micro albuminuria anddiabetic retinopathy. Several factors like increase in age,duration of diabetes, HbA1c levels on admission and bodymass index are associated with increased prevalence of microalbuminuria and diabetic retinopathy

Anthropometric Study Of External Ear In North Indian Population

Introduction: Anthropometry is a series of systematize measuring techniques that express quantitatively thedimensions of human body and skeleton which shows variation according to age, gender and race. Theidentification of an individual by age and sex possesses difficulty in revealing its identify. Various parametershave been used to establish the identification of individuals. Anthropometry of external features of the pinna isone of them.Objective: The aim of study to differentiate the morphometric features of external ear among males and femalesand also between the right and left ear in each gender.Materials and Methods: The study was conducted on 100 students which consist of 62 males and 58 female MBBSstudents with the age between 18-25 years in Rama Medical College, Hospital & Research Centre, Kanpur.Following anthropometric parameters used were: Height of ear (HE), Width of ear (WE), lobular height (LH),Lobular width (LW), Auricular index (AI) and Lobular index (LI).Results: In the present study, that all the parameters of right ear slightly greater than left ear among malepopulation except LW and LI. All the parameters of left ear slightly greater than right ear among female populationexcept HE and WE. The mean of HE,WE and AI of right ear slightly greater than left ear among combined (male +female) population whereas LH, LW and LI which were slightly lesser on right side than left side. All the parametersof external ear greater in males than female except LH on both sides which were greater in females than males.Conclusion: This anthropometric study is useful in the plastic reconstructive surgeries to correct the deformitiesand also useful in making the hearing aids or prosthesis, ear phones and head phones.

Effectiveness Of Surgical Management Of Ankle Fractures In Attaining The Stability Of Ankle

Introduction:Ankle injuries comprise a major group of lower limb trauma. Many of these injuries can be treated by manipulative reduction and conservative treatment and some of these yield satisfactory results, so present study was undertaken to know the effectiveness of surgical management of ankle fractures. Method:42 surgically treated dis-placed fractures are included and studied in detail of age, sex, occupation, type of fracture, mode of injury, type of treatment, Clinical evidence of fracture union, Radiological evidence of fracture union, Relation of talus in the ankle mortise, Range of mobility of the ankle, Residual disability and pain, Ability to walk and time of return to duty and complications were noted. Result:42 cases were surgically treated, most of the patients were operated on an emer-gency basis within 24 hours of injury. Based on the mechanism of injury Pronation-External Rotation (30.9%) and Based on Ao Classification Type B -B2 (53.3%) were the major type of fractures. In the majority of cases, Malleolar screws type of implants used.In overall the final status of patients is good (ability to walk).Conclusion:Displaced ankle fractures need accurate open reduction and internal fixation and postoperative immobilization for 6 weeks. This will suffice to get good results. Post-operative rigid immobilization and protected weight bearing for 12 weeks is mini-mal to achieve good union followed by physiotherapy to restore the maximum range of movements

Prevalence and Molecular Analysis of Novel Newly Identified Periodontal Pathogens in Subgingival Plaque Samples of Saudi Patients with Chronic Periodontitis

Objective: To evaluate the prevalence of novel newly identified periodontal pathogenic strains in subgingival plaque samples and relate it with bleeding on probing, probing pocket depth and age. Material and Methods: 268 chronic periodontitis patients with a mean age of 46.0 ± 6.0 years were included. The following microorganisms were evaluated: Campylobacter gracilis (Cg), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg), and Tannerella forsythia (Tf). Full mouth examination was registered; the probing pocket depth and clinical attachment level were assessed at six sites per tooth. Dental subgingival plaque samples were taken in the deepest pocket per arch in the maxilla and mandible. DNA analysis was performed using DNA-strip technology. Pearson's correlation coefficient was used for statistical analysis. Results: Porphyromonas gingivalis and Tannerella forsythia were detected at high level of 80% and 82% respectively. F nucleatum revealed a rate of 94%. Bacterial load significantly increased by increasing mean probing depth of the examined sites. Pearson's coefficient was the highest for Pg (r=0.62, p=0.0001) and the lowest for Cg (r=0.08, p=0.04). The bacterial load significantly increased by increasing the number of bleeding sites; Pearson's coefficient varied from r= 0.14 for Pg (p=0.01) to r=0.39 for Tf (p=0.001). Conclusion: It was confirmed the presence of main putative periodontal pathogens detectable in Saudi periodontal subjects, also providing a comprehensive view for correlation of these putative periodontal pathogens with the increase in probing pocket depth to the presence and load of all the bacterial species.

Socket preservation using eggshell-derived nanohydroxyapatite with platelet-rich fibrin as a barrier membrane: a new technique

OBJECTIVES@#Socket grafting is vital to prevent bone resorption after tooth extraction. Several techniques to prevent resorption have been described, and various bone graft substitutes have been developed and used with varying success. We conducted this pilot study to evaluate the performance of nanohydroxyapatite (nHA) derived from chicken eggshells in socket preservation.@*MATERIALS AND METHODS@#This was a prospective, single center, outcome assessor-blinded evaluation of 23 sockets (11 patients) grafted with nHA and covered with platelet-rich fibrin (PRF) membrane as a barrier. Bone width and radiographic bone density were measured using digital radiographs at 1, 12, and 24 weeks post-procedure. Postoperative histomorphometric and micro-computed tomography (CT) evaluation were performed. The study protocol was approved by the Institutional Ethics Committee.@*RESULTS@#All patients had uneventful wound healing without graft material displacement or leaching despite partial exposure of the grafted socket. Tissuere-epithelialized with thick gingival biotype (>3 mm). Width of the bone was maintained and radiographic density increased significantly with a trabecular pattern (73.91% of sockets) within 12 weeks. Histomorphometric analysis showed 56.52% Grade 3 bone formation and micro-CT analysis revealed newly formed bone with interconnecting trabeculae.@*CONCLUSION@#Use of a PRF membrane with nHA resulted in good bone regeneration in sockets. Use of a PRF membrane prevents periosteal-releasing incisions for primary closure, thereby facilitating the preservation of keratinized mucosa and gingival architecture. This technique, which uses eggshell-derived nHA and PRF membrane from the patient's own blood, is innovative and is free of disease transfer risks. nHA is a promising economic bone graft substitute for bone regeneration and reconstruction because of the abundant availability of eggshell waste as a raw material.
