Background: Based on the present global burden of oral diseases, unmet dental needs affect a more significant population worldwide. It is characterised by the need for dental care but receiving delayed or no care. The contributing factors include lack of knowledge about oral health, its consequences, and the availability of dental services. We need to find out the scale of the problem of unmet dental needs for the south Indian population. Therefore, the objective was to determine the relationship between the presence of oral disease and the quality of life-related to oral health using the OHIP-14 tool. Methods: The unmet dental requirements of the south Indian population were determined using a cross-sectional questionnaire survey. Close-ended questions were used to obtain data from two investigators trained to record the answers from the patients. The data was collected using the OHIP-14 questionnaire, which consists of 14 items divided into seven domains with two questions each. Physical pain, psychological impairment, physical disability, psychological disability, social disability, and disability were all considered. An additional analysis of artificial neural network (ANN) was done. Results: The response rate was 100 per cent. N = 1029 people replied to the questionnaire about their unmet dental needs. N = 497 (48.3%) were men, whereas N = 532 (51.7%) were women. The average age was 31.7811.72. As their current occupation, most of the included subjects (60.1%) were students. The respondents had no known personal habits and a mixed diet (94.93%). The average BMI was 24.022.59 (14-30.9). OHIP was present in 62.3% of the population. The average OHIP-14 severity score was 10.97. (8.54). The severity and degree of unmet dental need were substantial (p0.01) due to pain in the mouth/teeth/gums, malocclusion, and gum bleeding. The most common OHIP-14 domains affected by unmet oral needs were psychological discomfort, psychological limitation, social limitation, and feeling handicapped. The analysis of ANN revealed that high OHIP scores were primarily attributed to dental caries, poor oral health, and dental aesthetics. Conclusion: The severity and degree of unmet dental needs were significant among the south Indian population. The most common oral health status that impacted OHIP-14 domains were pain, malocclusion, and bleeding gums. These patients were significantly impacted by psychological discomfort and social limitations and felt handicapped. [ABSTRACT FROM AUTHOR]

Introduction: Furcation regions present some of the most significant challenges to the successful outcome of periodontal therapy. Due to their anatomical complexities, the areas become inaccessible, and instrumentation is generally tricky and often incomplete. Hence, it is essential to have a thorough knowledge of molar anatomy to assess the case difficulty, appropriate diagnosis, and treatment planning. Aim: To radiographically evaluate and classify the furcation anatomy of mandibular first and second molars based on root trunk length and root divergence angle. Materials and Methods: This retrospective observational study was carried out in AB Shetty Memorial Institute of Dental sciences, Mangalore between February and March 2020. Orthopantomograms (OPG) with permanent healthy first (25 right and 25 left) and second mandibular molars (25 right and 25 left) with no alveolar bone loss obtained from systemically healthy individuals were selected for the study. They were screened for root divergence angle and root length to root trunk length ratio. According to the root divergence angle, the total sample was classified as Group I (with angle <30°), Group II (with angle 30°to 60°), Group III (with angle >60°). They were classified into Type A, B, and C based on Hou and Tsai classification. Type A root trunks involving the cervical third or less, Type B involves upto cervical half of the length of the root and Type C involves cervical two-thirds of the root, respectively. The data were collected and entered in the Microsoft Excel sheet. Mean and standard deviation was calculated for root divergence. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 23.0. Student t-test was used to compare intragroup variations in root divergence in the left and right molars. The p<0.05 was considered to be significant. Results: Total 100 teeth (50 mandibular first molar (25 left and 25 right) and 50 mandibular second molars (25 left and 25 right)) were included in the study and analysed. In terms of Furcation Angle (FA), mandibular left first molar showed an increased frequency of Group II (48%) and Group III (48%), while mandibular left second molar showed an increased frequency of Group II (68%). Among mandibular right first molar Group III (56%) showed an increased frequency, while Group II (92%) was commonly seen in right second molar. Intergroup comparison revealed a statistically significant difference in divergence between mandibular left first and second molars (36 and 37) p<0.01, mandibular right first and second molars (46 and 47) (p<0.01). Divergence of furcation was more significant in 36 and 46 than 37 and 47, respectively. The current study results showed a higher frequency of Type A in all the four involved teeth, i.e., left first (96%) and second (68%) molars, right first (92%) and second (88%) molars. Conclusion: The study results showed an increased frequency of Group II FA and Type A root trunks. The divergence of furcation was greater in first molars compared to the second molars.

It is a fact that diabetes affects 9.3% of the world's population and the number of afflicted individuals is anticipated to increase by 11% by 2045. Diabetes mellitus (DM) is a category of metabolic disease characterized by hyperglycemia caused by abnormalities in insulin production, insulin action, or both. It is also attributed to a number of micro and macrovascular problems, the etiology of which is complicated and involves metabolic and hemodynamic abnormalities such as hyperglycemia, dyslipidemia, insulin resistance, and immunological dysfunction. Since the oral cavity is likewise extensively vascularized and innervated, diabetic oral sequelae are to be expected. Despite the fact that there is significant data supporting the link between diabetes and dental health, there is a lack of oral health knowledge among health professionals and even diabetic patients. In this review, we will assess potential oral complications, elaborate on the pathogenic mechanisms and some literature studies that might explain the associations between DM and potential oral manifestations.

Context: Periodontitis and chronic obstructive pulmonary disease (COPD) are chronic progressive inflammatory conditions. Smoking has been associated with both chronic periodontitis and COPD. Hence, the present study was designed to correlate serum levels of cotinine with the severity of periodontal disease with or without COPD. Settings and Design: A total of eighty patients, twenty healthy individuals, twenty patients with chronic generalized periodontitis without smoking and without COPD, twenty patients who are smokers with chronic periodontitis without COPD and twenty patients who are smokers with chronic periodontitis and COPD in the age range of 43–65 years were selected for the study. Subjects and Methods: Serum cotinine level assessment, smoking history, and periodontal examination were done in all the patients and the data obtained were statistically analyzed. Results: The mean serum cotinine level was highest in smokers with chronic periodontitis and COPD (93.642 ± 14.727) and it differed significantly between the four groups (P < 0.001). There is a significant positive correlation between the number of cigarettes and serum cotinine levels in both groups involving smoking. There was no significant correlation between serum cotinine level and clinical attachment loss in chronic periodontitis smokers with or without COPD. Conclusions: The result of this study indicates that increased smoking with COPD causes a higher chance of progression of periodontal destruction but it is not statistically significant. Furthermore, this study indicates that the assessment of serum cotinine levels is a reliable method to evaluate smoking exposure. [ABSTRACT FROM AUTHOR]

Introduction: The purpose of this research was to evaluate the serum level of vitamin C in patients with type 2 diabetes mellitus with and without periodontitis, and also to interpret whether raised or lessened serum vitamin C levels might be associated to a possibility for building oxidative stress in type 2 diabetes mellitus with periodontitis. Material and Methods: Investigation was conducted on diabetic subjects with and without periodontitis. The serum vitamin C level was determined using the 2, 4-dinitrophenylhydrazine method, and the spectrometer was used to read the concentration of serum vitamin C. The data attained were statistically calculated using the ANOVA test and post-hoc test. Results: The findings revealed that average serum vitamin C levels were reduced considerably among test groups (groups B, C, D) (p< 0.0001) in contrary to the healthy control group. Conclusion: The existing results are proof that reduced concentration of antioxidants such as vitamin C is related to a greater threat to the increase of oxidative stress in patients with type 2 diabetes mellitus and periodontitis.

Background: Periodontal diseases are a group of inflammatory conditions resulting from interaction between a pathogenic bacterial biofilm and susceptible host's inflammatory response eventually leading to the destruction of periodontal structures and subsequent tooth loss. Hence, investigation of salivary proteins in individuals with periodontal diseases may be useful to enhance the knowledge of their roles in these diseases. Materials and Methods: This case-control study was conducted at A.B. Shetty Memorial Institute of Dental Sciences, Mangalore. The study comprised of 90 patients of age between 25-60 years who were clinically examined and divided into three groups of 30 each: namely clinically healthy, gingivitis and chronic periodontitis. These were classified according to the values of gingival index score, clinical attachment loss and probing pocket depth. Unstimulated saliva was collected and salivary mucin, amylase and total protein levels were determined. Statistical analysis: Results obtained were tabulated and statistically analyzed using ANOVA test and Karl pearson's correlation test. Results: The results of the study showed an increased concentration of salivary mucin, amylase and total protein in gingivitis patients and increased levels of amylase and total protein in saliva of chronic periodontitis patients compared to healthy individuals which were statistically significant. Adecrease in mucin concentration was observed in the periodontitis group compared to gingivitis group. A positive correlation was present between salivary mucin, amylase and total protein levels in the three groups. Conclusion: Salivary mucin, amylase and total protein may serve as an important biochemical parameter of inflammation of the periodontium. Also, it can be hypothesized that various enzyme inhibitors might be useful as a part of host modulation therapy in the treatment of periodontal diseases. [ABSTRACT FROM AUTHOR]

Introduction: Magnesium is an essential cation playing a crucial role in many physiological functions and its imbalance is associated with greater number of pathological situations. Oxidative stress is usually increased due to decreased essential nutrients. Hence, any imbalance of essential nutrients like serum magnesium can significantly play a role in the pathobiology of periodontitis in the presence of diabetes, as diabetes and chronic periodontitis are two chronic diseases that have been biologically linked. Aim: To evaluate the association of serum magnesium in type 2 diabetes mellitus and chronic periodontitis patients, also to evaluate and associate the influence of serum magnesium on periodontal health. Materials and Methods: A single blinded, randomized study was conducted that comprised of 120 subjects divided into four groups. Individuals with periodontitis and type 2 diabetes mellitus formed the test group. Subjects with chronic periodontitis diagnosed clinically according to 1999 American Academy of Periodontology classification, without any medical history and drug history were included as the study subjects. Gingival Index and Plaque Index were scored for all the groups at baseline and after 21 days of scaling and root planing. Scaling and root planing was done only in the test group. Blood was drawn from the patients at baseline and 21 days after scaling and root planning and estimation of serum magnesium level was done using semi-autoanalyzer. Data obtained was statistically analyzed using the paired t-test, one-way ANOVA, post-hoc test. Results: The result of the present study showed that mean serum magnesium among healthy was 1.40±0.565mmol/l as compared to 1.01±0.287mmol/l among subjects with periodontitis, 0.920±0.23mmol/l among diabetics with periodontitis and 0.93±0.29mmol/l among diabetics without periodontitis. Serum magnesium was significantly decreased in chronic periodontitis and diabetic patients with and without chronic periodontitis as compared to controls. Conclusion: Imbalance of serum magnesium level was seen in patients with chronic periodontitis and type 2 diabetes mellitus. Hence, it can be a biomarker which can predict the occurrence of type 2 diabetes mellitus and chronic periodontitis. [ABSTRACT FROM AUTHOR]
