Effect of malocclusion severity on oral health and its correlation with socioeconomical status in Iranian adolescents

BackgroundThis study aimed to assess the effect of malocclusion severity according to the Index of Treatment Need (IOTN) on oral health (dental caries and gingivitis), and its correlation with socioeconomic status (SES) in Iranian adolescents.MethodsThis descriptive cross-sectional study was conducted on adolescents between 10 and 16 years in Tehran city, who underwent clinical dental examination. The Dental Health Component (DHC) of the IOTN was used to assess the severity of malocclusion. The DMFT index was calculated to assess dental caries, and the gingival index (GI) was calculated for gingival health assessment. For oral hygiene assessment, the Oral Hygiene Index-Simplified (OHI-S) was calculated, and a questionnaire was used.ResultsTotally, 306 adolescents participated in this study. The frequency of IOTN grades was 88 (28.8%), 89 (26.1%) ,49 (16%), 60 (19.6%), and 29 (9.5%) for grades 1 to 5, respectively. The multinomial logistic regression showed that by an increase in OHI-S score, the odds of having IOTN grade 4 compared to grade 1 increased. Postgraduate parental level of education decreased the odds of having IOTN grade 4 compared to grade 1. Furthermore, there was an inverse correlation between oral hygiene practice and the odds of having IOTN grade 5 compared to grade 1.ConclusionsMalocclusion may hinder oral hygiene practice, and resultantly increase plaque accumulation. This risk may be amplified in children with lower SES, highlighting the need for preventive and educational oral health programs.

Exploring the Implications of Cultural Dental Mutilation on Periodontal Health: A Study on Mentawai Women's Traditional Teeth Sharpening

Teeth sharpening is a part of the Mentawai tribe’s rich cultural legacy and is done by women upon reaching adulthood in Indonesia. However, it has been linked to negative impacts on oral health, particularly in the periodontal tissues. This paper studied the periodontal tissues of Mentawai women who have undergone teeth sharpening, considering potential specific implications. Employing a descriptive approach, this cross-sectional study was conducted across four villages in Mentawai Island, Indonesia. Oral Hygiene Index-Simplified (OHIS) and the Gingival Index (GI) were used to assess the periodontal status of eight Mentawai women who had undergone teeth sharpening. The study revealed a notable absence of optimal periodontal tissue health among respondents with suboptimal oral hygiene practices (OHIS score 3.4) and considerable gingival inflammation (GI score 2.2). The presence of supragingival and infragingival calculus, alongside visible stains across the teeth of Mentawai women were due inadequate of oral health care behavior. In addition, the findings underscore the intricate interplay between cultural practices and gender-specific health outcomes. A deeper understanding of health behaviors, as influenced by culture, health beliefs, acculturation, and attitudes, is needed to formulate appropriate oral health promotion policies. A gender-informed perspective will encourage a broader dialogue about preserving cultural heritage as well as empowering the role of women in their family and community on oral health improvement. The implementation of this analysis would be developing the best strategy for modifying this custom in order to keep it while preserving oral health.

Effectiveness of Reinforced Oral Health Education on the Oral Hygiene Status of 9–12-year-old Primary Schoolchildren: A Follow-up Study

Abstract Background: In the society, school is a significant formal unit where implementation of health programs can help in improving children’s educational and health status. The impact of repeated reinforcement of oral health education on schoolchildren can provide substantial evidence for policymaker. Thus, a follow-up study was conducted to assess the effectiveness of reinforced oral health education on the oral hygiene status of primary schoolchildren. Materials and Methods: The present follow-up study was conducted among primary schoolchildren in Mangalore, Karnataka, India for a duration of 8 months from January 2015 to August 2015. Multistage sampling method was used. The primary investigator collected data using an Oral Hygiene Index-Simplified (OHI-S). Impact of oral health education repeated reinforcement on retention of proper behavior among schoolchildren toward oral health and oral hygiene practices. Friedman test for comparison among different time interval. Wilcoxon signed-rank test was used for intragroup comparison. Results: Nearly 83.3% of study subjects were using toothbrush and toothpaste to clean their teeth. About 88.1% of study subjects had never visited a dentist ever. A statistically significant difference was observed at three different time intervals for debris, calculus, and OHI-S score (P < 0.05). Discussion: On intragroup comparison between three time intervals, study results reported a significant improvement in oral hygiene at 4 months and 8 months (P < 0.01). It shows that reinforcement of oral health education at regular time intervals had a significant positive impact on oral hygiene status.

State of Dental Health and Management Needs of Young Hemophilic Patients: A Case-control Study.

In particular, when it comes to systemic diseases like hemophilia, good dental health is crucial to a person's overall health and wellness. Through the means of this study, we aim to assess the prevalence of various dental anomalies in children suffering from hemophilia in comparison to healthy children and assess their treatment needs. This was a descriptive, case-control study with 400 subjects, 200 each in the study (hemophilic) and control (nonhemophilic) groups. The subjects' ages ranged from 5 to 15 years. Utilizing the oral hygiene index-simplified (OHI-S), the state of oral hygiene was documented (OHI-S). Using decaying extracted filled tooth (DEFT) and decayed, missing, and filled tooth (DMFT) for the primary and permanent dentition, respectively, teeth afflicted by dental caries and teeth restored/extracted as a result of dental caries were assessed. Statistical Package for the Social Sciences (SPSS) software (version 27.0) was used for statistical analysis. Hemophilic people had a considerably greater incidence of dental caries. Furthermore, even though their DMFT/DEFT and OHI-S scores were barely poorer than those of healthy people, children with hemophilia had a significantly larger percentage of dental treatment needs across all age categories than the other group. The percentage of hemophilic children who needed dental treatment across different age groups was significantly higher than the other group, which supports our observations that the dental health status of hemophilic children was poor and treatment requirement was high among them as well. This is true even though the DMFT/DEFT scores and OHI-S scores in hemophilic children were only slightly worse than in healthy individuals. Sharma S, Shahi AK, Chandra S, et al.

Evaluation of periodontal status in women with polycystic ovary syndrome versus healthy women: a cross-sectional study.

Polycystic ovary syndrome (PCOS) affects approximately 4% to 12% of females of reproductive age. Previous studies have shown an association between systemic and periodontal diseases. This study aimed to compare the prevalence of periodontal disease in women with PCOS and healthy women. A total of 196 women aged 17 to 45 years were included in this study. Oral hygiene index-simplified (OHI-S), gingival index (GI), community periodontal index (CPI), and loss of attachment (LA) were assessed. Individuals who smoked, were pregnant, had any systemic disease (such as type 1 or type 2 diabetes mellitus, cardiovascular disease, malignancy, osteoporosis, and thyroid dysfunction), had a history of systemic antibiotic use in the past three months, or received any periodontal intervention in the past 6 months of screening were excluded. Student t-test was used to analyze the data. A p-value of <0.05 was considered statistically significant. Despite similar OHI-S scores (p=0.972) in the two groups, women with PCOS had significantly higher GI, CPI, and LA scores than healthy women (p<0.001). Periodontal disease was more prevalent in women with PCOS than in healthy women. This finding may be due to the synergistic effects of PCOS and periodontitis on proinflammatory cytokines. PCOS may have an effect on periodontal disease, and vice versa. Hence, education on periodontal health and early detection and intervention for periodontal diseases is of paramount importance in patients with PCOS.

The Effect of Anterior Crowding Toward Oral Hygiene Index-Simplified and Gingival Index Score

Dental crowding is one form of malocclusion characterized by disparities between the size of the tooth and the arc dimension. It is commonly found in the anterior region. Keeping the crowded and misaligned tooth is hard, leading to more plaque accumulation and increasing the risk of gingival inflammation. This research aims to find the effects of anterior dental crowding on the Oral Hygiene Index-Simplified (OHI-S) and Gingival Index scores of Poltekkes Kemenkes Kupang students. This is a cross-sectional study performed by observational analytical study design. The population was the student of Poltekkes Kemenkes Kupang with anterior crowding. Using 70 samples were chosen using purposive sampling technique. The result showed that most of the students had moderate anterior crowding (45.7%), followed by mild crowding (30%) and severe crowding (20%). The chi-square test showed a significant effect of anterior crowding toward OHI-S (p=0.03) and GI scores (p=0.04). While Socio-economical aspect also showed a significant effect (p=0.00) on OHI-S scores. A significant effect of socioeconomic status was also recorded on GI score (p=0.00). An observation of the students' oral hygiene intention showed that they mostly had a moderate intention (72.9%) to keep their mouth clean, and the rest, 27.1% had high oral hygiene intention. This aspect also significantly affects their scores of OHI-S (p=0.00) and GI (p=0.01). This study concluded that anterior crowding, socioeconomic status, and oral hygiene intention can affect OHI-S and GI scores of the students of Poltekkes Kemenkes Kupang

Effectiveness of Two Dental Educational Programs on the Oral Hygiene Status Among a Group of Visually Impaired Children

Purpose: To assess the effectiveness of Audio and Audio-Tactile Performance (ATP) educational programs on oral hygiene status among a group of visually impaired children by Oral Hygiene Index Simplified(OHI-S) and assess the effectiveness of this programs in improving their oral hygiene knowledge, attitude and practice (KAP) and their satisfaction toward oral health via questionnaire before and after the programs. Subjects and methods: A total of 86 visually impaired children ranging from (6-12) years were divided into two groups. (Group I):45 children who received the Audio method educational program. (Group II):41 children who received the Audio Tactile Performance method. The oral hygiene status was assessed for both groups by Oral Hygiene Index Simplified (OHI-S) at baseline and at two follow up examination after three months and six months. Questionnaires were taken at the baseline and at the end of the study to assess their oral hygiene knowledge, attitude and practice (KAP) and their satisfaction toward oral health. Results: No statistically significant difference in OHI-S scores between the two groups after 3 months from the beginning of the educational programs. A statistically significant difference in OHI-S scores between the two groups after 6 months from the beginning of the educational programs. A significant improvement in participant knowledge, attitude and practice (KAP) and their satisfaction toward the oral health in both groups after the educational programs. Conclusion: Children with visual impairment could maintain accepted degree of oral hygiene, when taught by special customized techniques. Also for maintenance of oral hygiene practices, a regular reinforcement is required.

A Randomized Controlled Trial for Evaluation of the Effectiveness of Oral Irrigator and Interdental Floss for Plaque Control in Children with Visual Impairment.

To evaluate the effectiveness of oral irrigator and interdental floss as adjuncts to manual tooth brushing in 8-16 years old children with visual impairment. A three-arm, parallel-group randomized controlled trial with blinded outcome assessment was carried out with the inclusion of 90 institutionalized children with visual impairment of age 8-16 years. They were equally allocated to three groups: group I: tooth brushing along with interdental flossing, group II: brushing along with a powered oral irrigator, and group III: brushing alone (control). Baseline oral hygiene index-simplified (OHI-S), gingival index (GI), and plaque index (PI) scores were recorded for all the samples and compared with post-intervention scores at 14 and 28 days intervals. Repeated measures of analysis of variance (ANOVA), one-way ANOVA, and post hoc Tukey tests were used for statistical analysis. At 28 days interval, children in group II showed a highly statistically significant reduction in OHI-S (0.46; p = 0.0001), PI (0.16; p = 0.0001), and GI (0.24; p = 0.0001) scores compared to control group. They also showed a significant reduction in OHI-S (0.25; p = 0.018), PI (0.15; p = 0.011), and GI (0.15; p = 0.0001) scores compared to group I. There is no significant reduction in the scores of children of group I compared to control group except for the GI score (0.08; p = 0.02). Oral hygiene maintenance using oral irrigator along with brushing was found to be more effective in visually challenged children. Interdental flossing, along with brushing and brushing alone was found to be less effective. This study underlines the fact that comprehensive oral hygiene care should include interdental cleaning aids for effective plaque control to prevent dental diseases in children with visual impairment. Since these children have less manual dexterity to perform good oral hygiene practices, electrically driven interdental cleaning aids like oral irrigator may help them to overcome the problem.

Differences in the oral hygiene status and clinical periodontal status between conventional and electric smokers

Conventional and electrical cigarette use could result in bad pathological conditions in the oral cavity, which may lead to periodontal diseases. This research aimed to determine the differences in the oral hygiene and clinical periodontal status between conventional and electric smokers. This research was a quantitative observational research and was designed as a cross-sectional study. The samples were selected using purposive sampling. A total of 110 respondents (n = 110) were involved, consisted of 60 conventional smokers and 50 electric smokers. Their oral hygiene status were examined using oral hygiene index simplified (OHI-S) measurement, while their periodontal tissue status were assessed using bleeding on probing (BOP) and probing pocket depth (PPD) measurements. The data were analyzed using the Mann-Whitney test with a significance level of α &lt; 0.05. The median and first quartile of OHI-S scores of the conventional smokers’ group were 2.7 and 2.2, while the electric smokers’ group was 2.2 and 1.4 respectively, with a significant value of p &lt; 0.001. The median and first quartile BOP scores of the conventional smokers’ group were 36% and 29%, while the electric smokers’ group were 35% and 28% respectively, with a significant value of p = 0.750. The median and first quartile of PPD scores in the conventional smokers’ group were 3.2 and 2.7, while the electric smokers’ group were 3.1 and 2.6 respectively with a significant value of p = 0.765. Conventional smokers had worse oral hygiene status than electric smokers. Conventional and electric smokers did not have significant differences in periodontal health including gingival bleeding and poor pocket depth.

Trends in Self-Rated Oral Health and Its Associations with Oral Health Status and Oral Health Behaviors in Japanese University Students: A Cross-Sectional Study from 2011 to 2019.

Self-rated oral health (SROH) is a valid, comprehensive indicator of oral health status. The purpose of this cross-sectional study was to analyze how oral health behaviors and clinical oral status were associated with SROH and how they had changed over the course of nine years in Japanese university students. Data were obtained from 17,996 students who underwent oral examinations and completed self-questionnaires from 2011 to 2019. Oral status was assessed using the decayed and filled teeth scores, bleeding on probing (BOP), probing pocket depth, the Oral Hygiene Index-Simplified (OHI-S), oral health behaviors, and related factors. SROH improved from 2011 to 2019. The logistic regression model showed that university students who were female and had a high daily frequency of tooth brushing, no BOP, no decayed teeth, no filled teeth, and a low OHI-S score and were significantly more likely to report very good, good, or fair SROH. An interaction effect was observed between survey year and regular dental check-ups (year × regular dental check-ups). The improvement trend in SROH might be associated with changes in oral health behaviors and oral health status.

Dental caries, oral hygiene status and treatment needs of fishermen and non-fishermen population in South Goa, India.

Occupation plays a major role in the well-being of an individual and has an influence on oral health. Fishing is one such occupation that entails a lot of physical labour and encourages habits that lead to poor oral health. Therefore, it is critical to shed light on the oral health of this isolated population to improve their quality of life by various means. The aim of the study was to assess and compare the prevalence of dental caries, oral hygiene status and treatment needs of fisherman and non-fisherman population in South Goa, India. Study design was cross-sectional in nature. After a pilot study, multi-stage random sampling technique was employed and 400 study participants were recruited. World Health Organization Oral Health Assessment Form (1997) and Oral Hygiene Index-Simplified (OHI-S) were used to record the study variables. Inter-examiner reliability assessed using Kappa statistics were found to be 90% and 88%, respectively. The data was analysed using descriptive analysis, Chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and linear and logistic regression analysis. Fishermen had significantly higher caries prevalence (82%) and poor oral hygiene (46%) than non- -fishermen. Extraction (42.2%) and pulp care (23.6%) were the highest treatment need among fishermen. They were 2.08 times more prone to dental caries than non-fishermen. Fishermen who used a toothbrush were 4.5 times less susceptible to caries. The dependence of caries prevalence and OHI-S score on occupation, oral hygiene aid and age were 14% and 25.8%, respectively. Fishermen in South Goa had high caries prevalence, poor oral hygiene status and they required extensive dental treatment when compared to non-fishermen.

Evaluation of Oral Health Status Among Pregnant Women Using Oral Hygiene Index- Simplified (OHI-S) Score

Background: Oral health of women is often neglected during pregnancy. We need to address this issue in a developing country’s perspective,as oral healthcare is not an integral part of antenatal protocols.Objective: To evaluate the oral health status of pregnant women using Oral Hygiene Index-Simplified (OHI-S) Score as well as explore oral hygiene practice by them and conduct a mini-assessment of their knowledge of oral health.Methods: This cross-sectional, descriptive study was conducted using data by using a semi-structured questionnaire among 170 pregnant women attending an antenatal center in Dhaka city, Bangladesh,from March to August of 2018. A pre-tested semi structured questionnaire containing OHI-S indexwas used for data collection. Dental mirror and probe were used for oral hygiene assessment.Results: The mean age of the participants was 24.22±5.07 years. 140(82.4%) were found to use toothbrushes as a tooth-cleaning aid and 146(85.9%) used toothpaste as a tooth cleaning material. Among them, 132(94.3%) were found to brush at least once a day. The predominant health problems identified by clinical examination among those pregnant women were gum bleeding, mild to severe periodontitis, halitosis (bad breath) and loose teeth. The majority didnot know the safe period of dental treatment and the consequences of having poor oral health during pregnancy. The overall oral hygiene status of the maximum pregnant women was ‘Fair’ (50.6%) (OHI-S score 0-1.2), while 39.4% had ‘Poor’ oral hygiene status (OHI-S score 1.3-3.0) and only 10% had ‘Good’ oral hygiene status (OHI-S score 3.1-6.9).Conclusion: Pregnant women in Bangladesh suffer from various oral health issues during pregnancy; however, they exhibit that they do not address this issue due to lack of awareness and other factors. Hence, it is crucial to plan and implement effective oral health programmes for pregnant women all over the country.International Journal of Human and Health Sciences Vol. 06 No. 03 July’22 Page: 298-303

The relationship between parents' oral hygiene knowledge and children with Down Syndrome's oral hygiene via OHI-S.

Background: Down Syndrome (DS) is a genetic disorder that causes structural, functional anomalies, and intellectual disability. The common oral hygiene problems found in DS children are gingivitis, periodontal problems, pain, infection, and problems with the masticatory system. This study explored the relationship between parents' oral hygiene knowledge and oral hygiene of children with DS. Method: This was an observational analytical study. To assess parents' oral hygiene knowledge, a questionnaire consisting of 25 questions was distributed to 100 parents whose DS children in POTADS (Down Syndrome Parents Association) Surabaya. To assess the DS children's oral hygiene, dental exams were performed to calculate the individual Oral Hygiene Index-Simplified (OHI-S) scores by dividing the sum of the individual debris and calculus scores by six (the number of teeth examined). The data were analysed using regression analysis. Results: There was a significant and strong inverse relationship between parents' oral hygiene knowledge and DS children's oral hygiene. Parents' oral hygiene knowledge affected DS children's oral hygiene. The results of the regression analysis indicated that a 1% increase in parents' knowledge caused a reduction in the OHI-S score to 7.377. Conclusion: A significant inverse relationship between parents' oral hygiene knowledge and DS children's oral hygiene was observed in this study. Further studies could be conducted to determine other variables that my influence both parents' oral hygiene knowledge and DS children's oral hygiene.

The relationship between parents' oral hygiene knowledge and children with Down Syndrome's oral hygiene via OHI-S.

Background: Down Syndrome (DS) is a genetic disorder responsible for mental and development retardation. DS occurs when a person has an extra chromosome (47 instead of 46), the third copy of the Trisomy 21 chromosome. This causes structural and functional anomalies in the human body and some degree of intellectual disability. Children with DS have poor oral hygiene as they are unable to understand and are unaware of its importance. Oral hygiene problems commonly found in children with DS are gingivitis, periodontal problems, pain, infection, and problems with the masticatory system. This study explored the relationship between parents' knowledge and maintenance of the oral hygiene of children with DS through the OHI-S (Oral Hygiene Index Simplified) Index Score. Method: This study was conducted by distributing 25 questions via Google Form to 100 subjects that belong to POTADS (Down Syndrome Parents Association. The participants were children diagnosed with Down Syndrome and their parents. Questionnaires were used to assess parents' knowledge about their child's oral hygiene. To assess the children's oral hygiene, dental exams were performed with the OHI-S on six tooth surfaces. To calculate the OHI-S score for each individual, the debris and calculus scores from the 6 surfaces of the teeth were totalled and divided by six. Results: The relationship between parents' knowledge and the maintenance of oral hygiene of children with DS was found by conducting a linear regression analysis and hypothetical test. The equation of Y = 77.734 + (-7.377) X was achieved through linear regression analysis, and indicated that a 1% increase in parents' knowledge caused a reduction in OHI-S score to 7.377. The hypothetical test showed that parents' knowledge affected their children's OHI-S score significantly. Conclusion: There was a significant contradictive relationship between parents' knowledge and the maintenance of oral hygiene of children with DS .

Picture exchange communication system as a behavior modification technique for oral health assessment in autistic children.

The aim of this study was to establish a modality for behavioral intervention for dental management in autistic children using Picture Exchange Communication System (PECS). A prospective interventional study was carried out on 30 autistic children in the age range of 4-18 years diagnosed with mild to moderate grades of autism to evaluate the effectiveness of PECS in improving oral health over a period of 6 months. PECS Phases showed a gradual rise from first to third visit, which was statistically highly significant (p < 0.001). Oral Hygiene Index-Simplified (OHI-S) scores improved significantly from first visit and second visit. Definitely substantial correlation was seen between PECS and OHI-S. Gradual decrease was observed in OHI-S scores over a period of 6 months, indicating an improvement in the oral hygiene status of autistic children. Gradual progress in Phases of PECS proved to increase cognitive ability of autistic children towards understanding the dental setup related PECS cards.

Effectiveness of Braille and audio tactile performance aid in improving oral hygiene status of visually impaired students

Aim: To assess the effectiveness of Braille and audio tactile performance (ATP) aid in improving oral hygiene status of visually impaired students. Materials and Methods: Randomized interventional study was conducted among 220 institutionalized visually impaired students aged 8–18 years for a period of 9 months. Study participants were divided into two groups, Group I (Braille) and Group II (ATP). Oral hygiene index-simplified (OHI-S) was used to assess their oral hygiene status at baseline and post intervention at the end of 9 months. Health education as intervention was given in Braille and ATP aid once in 2 months. Pre- and post-intervention OHI-S scores were compared. Results: The mean OHI-S scores in Group I reduced from 1.83 ± 0.68 to 1.79 ± 0.67, and P value was not found to be statistically significant (P = 0.21). Group II OHI-S scores reduced from 1.8 ± 0.66 to 1.75 ± 0.65, and P value was found to be statistically significant (P = 0.03). Conclusion: This study concluded visually impaired students can maintain an acceptable level of oral hygiene when taught using ATP technique.

Association between oral hygiene status and dental caries among 13–14 years old children of Kamrup District, Assam

Background: Dental caries and periodontal problems are mainly caused due to poor oral hygiene practices. Aim: This study aims to determine the relationship between oral hygiene status and dental caries in 13–14 years old school-going children of rural and urban locality in Kamrup Metropolitan District, Assam. Materials and Methods: A total of 1501 school children in the age group of 13–14 years were included in the study and dental caries was recorded from decayed missing filled teeth (DMFT) index as described by World Health Organization (1997) and Oral hygiene status was assessed using Oral Hygiene Index-Simplified (OHI-S) given by Greene and Vermilion 1964. The unpaired t-test, Chi-square test, and Pearson correlation test were used to assess the relation between oral hygiene status and dental caries among different age groups, and location of the school-going children using SPSS version 21 and P < 0.05 was considered to be statistically significant. Results: The results showed a significant positive correlation (P < 0.05) between mean OHI-S score and decayed component of DMFT score among rural school children whereas in urban children a significant positive correlation (P < 0.05) was found between mean OHI-S score and mean score of Decayed, Missing and Filled teeth component of DMFT. Conclusion: The overall prevalence of dental caries among school children of Kamrup (Metropolitan) District was 33.6%. The present study showed a significant positive correlation of mean OHI-S score with a mean of decayed teeth and DMFT score.

Background:To evaluate the association between stress and periodontitis in different professional college students.Subjects and Methods:The study was conducted in 360 professional college students which includes Medical, Dental, Pharmacy, Nursing, Engineering, and Chartered Accountancy. From each group, 60 students were included in the study. Self-reported Depression, Anxiety, and Stress Scale questionnaire was given to all the students and clinical examination was conducted in all the participants to assess the Oral hygiene index - simplified (OHI-S), clinical attachment level (CAL), and Gingival Index Simplified (GI-S).Statistical Analysis:Statistics was performed using the ANOVA test, post hoc test, and Pearson correlation test to compare the psychological parameter of stress with periodontal parameters among six groups of students. P <0.05 was considered to be statistically significant.Results:Group I showed higher mean stress scores (10.78 ± 0.76) compared to other groups. The mean OHI-S (1.61 ± 0.15), mean CAL (3.68 ± 0.79), and mean GI-S (1.43 ± 0.15) scores also increased with elevated stress levels among medical students. Followed by Group VI and Group II showed almost similar results.Conclusion:The present study showed strong association between stress and periodontal disease and have an adverse effect over oral hygiene factors among the students.

Use of Collagen Membrane in the Treatment of Periodontal Defects Distal to Mandibular Second Molars Following Surgical Removal of Impacted Mandibular Third Molars: A Comparative Clinical Study.

Simple SummaryRegeneration of the wounded/lost tissues post-surgery often requires a meticulous treatment plan. The present study assessed the use of a collagen membrane to aid in the regeneration of lost periodontal tissues following extraction of the tooth. The results show that the collagen membrane promoted wound stabilization, as indicated by improvement in all assessed clinical parameters. Thus, collagen membrane can be used regularly in clinical practice post-extraction to augment wound healing.The study aims to assess the efficacy of using collagen membrane in the treatment of distal periodontal defects of mandibular second molars following the removal of mesioangularly or horizontally impacted mandibular third molars surgically. Forty sites in twenty patients with bilaterally impacted mandibular third molars (mesioangular or horizontal) were considered for the study. In 20 test sites (Group A), after surgical removal of the mandibular third molar, a resorbable collagen membrane barrier was placed on the distal aspect of the mandibular second molar to cover the post-surgical bone defect. In the other control 20 sites (Group B), the same surgical procedure was repeated without placing any membrane barrier. The clinical parameters recorded were Oral Hygiene Index Simplified (OHI-S), Probing pocket depth (PPD), Clinical attachment level (CAL), and radiographic assessment of alveolar bone level (ABL). OHI-S score of most of the patients was observed to be satisfactory. Group A was observed to achieve a statistically significant reduction in PPD, CAL, and ABL gain compared to Group B. The improvements indicated that the use of collagen membrane facilitates early wound stabilization and promotes primary closure of the defect. This recovery is achieved through its unique property to assist fibrinogenesis over osteoconduction. Further longitudinal studies are needed to confirm the present findings.
