Assessment of the factors that affect the selection of a dentifrice among a population of 18-24-year-old students in Mangalore: A questionnaire survey.

Introduction: Bacterial plaque accumulation is the primary etiological factor for periodontal disease; hence, prevention of its accumulation is the cornerstone to any oral hygiene practice. Mechanical tooth cleaning by means of toothbrush and a dentifrice remains the most reliable and common method for controlling supragingival plaque. The objective of the study was to evaluate the factors considered while choosing a dentifrice and also to assess the role of socioeconomic status in determining these factors. Materials and Methods: This was a questionnaire study carried out among undergraduate students from the business and mass communication background of two private degree colleges in Dakshina Kannada, India. Two hundred and fifty-five students were included in the study. The questionnaire consisted of 24 close-ended questions. Results and Conclusion: The parameters of brand name, availability, and the flavor of the dentifrice are among the most accepted factors that a consumer takes into consideration in selecting a dentifrice. Parameters of influence (parents, colleagues, and celebrities), advertisement, and dentist recommendations of a dentifrice were also found to have a major influence on the consumer in selecting a dentifrice.

Evaluation of Risk Factors of Peri-Implant Disease Using a New Manual Risk Assessment Model: A Clinical study.

Background: Implants are being widely used as a treatment option and are considered the best line of treatment owing to their high level of predictability. However, over 5 years, 0-14.4% of dental implants have demonstrated peri-inflammatory reactions associated with loss of crestal bone and ultimately loss of the implant. Peri-implant diseases are categorized into peri-implant mucositis and peri-implantitis. There are a number of risk factors associated with these conditions, and the early detection of these possible risk factors, change in the treatment protocol whenever required along with a regular follow-up, can ensure a better survival rate of dental implants. In the present study, an attempt has been made to evaluate the risk factors associated with peri-implant diseases and also to correlate these risk factors to the prevalence of peri-implant diseases using the formulated risk assessment model. Methodology. The risk assessment model was prepared based on existing literature explaining the risk factors for peri-implant diseases. This study was conducted as a pilot study, and the method of complete sampling was used wherein all subjects in whom implants have been placed at the Department of Periodontology and Department of Prosthodontics were recalled and assessed. The model was then evaluated on patients in whom dental implants were placed and the implants were loaded for a year. A total of 13 subjects with 21 implants were assessed for the presence or absence of risk factors, and a score was given. Test of proportion and chi-square test was done. Results and Discussion. Of the 21 implants assessed, 15 implants were found to be at low risk and 6 implants with moderate risk of peri-implant disease. The number of implants with low risk was higher in implants with peri-implant mucositis (25%) whereas the implants with moderate risk was higher in implants with peri-implantitis (75%). This comparison was statistically significant with a p value of 0.022. Conclusion: This risk assessment tool can be used in the early detection of peri-implant disease, and identifying the risk factor may help in the success rate of the implant survival.

Pan-dent-emic: safety considerations for dental surgery in the era of COVID-19.

The global coronavirus disease 2019 (COVID-19) pandemic spread has seized the entire world and has created extensive health concerns in the general population. Despite various efforts to prevent the pandemic spread, the flare-up of this disease is still soaring due to the community spread in every area. The droplet spread from the afflicted is of the highest concern because of its rapid spread to uninfected individuals. Dental treatments have to be planned and carried out with extreme caution and dental personnel should take extreme care and follow meticulous guidelines when treating an individual with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection. This article highlights the clinical picture of COVID-19 (coronavirus diseases 2019) and presents a summary of precautionary and prophylactic measures in preventing the cross-infection and the nosocomial spread of the infection in a dental setting.

Evaluation of papilla levels following three different techniques for the second stage of implants - A clinical and radiographic study.

OBJECTIVE: Papilla formation after placement of an implant is influenced by the underlying bone and the periodontal biotype. The second-stage surgery to uncover the implants may have an effect on the regeneration of papilla and various techniques such as the scalpel, diode laser, and punch technique are used. In the present study, an attempt has been made to evaluate papillary fill levels following three different techniques of second-stage implant surgery. MATERIALS AND METHODS: A total of 35 patients with 45 implants (39 single implants and 3 sites with two adjacent implants) were randomly divided into three groups with 15 implants each: second-stage implant surgery with midcrestal incision using scalpel (Group I), with I-shaped incision using scalpel (Group II), and using diode laser (Group III). The mean papillary fill and mean crestal bone loss for all three groups were compared at baseline, 3 months, and 6 months of prosthesis delivery. RESULTS: Complete papilla fill at 6 months was seen in 60% and 73.3% of sites in Group II and Group III, respectively. Bone level contacting implant and adjacent teeth was less in both Groups II and III. Bone level from the contact point to the bone crest was least in Groups II and III. CONCLUSION: The use of diode laser during second-stage surgery showed maximum papillary fill and minimal crestal bone loss when compared with other two techniques. Irrespective of technique used for second-stage surgery, bone loss did occur after prosthesis delivery.

Pan-dent-emic: a dentist's dilemma in the COVID-19 era.

The aftermath of the COVID-19 pandemic has been unfathomable. It has affected every sector within health care industry with dentistry being one of the worst hits. Not only has it impacted the dental practice, the field of dental education has been affected as well. There has been loss in terms of delayed to no treatments, finances, psychology and most importantly breaks in ongoing education and research practices. The present article attempts to explain the dilemma of the current situation from a dentist's perspective. Since, the effects of the contagion are seen across each level of dentistry, the current situation can truly be termed as a "Pan-dent-emic".

Cellular and Biochemical Changes in Different Categories of Periodontitis: A Patient-based Study.

OBJECTIVES: The aim of this study was to study the effects of periodontitis, diabetes mellitus (DM), and tobacco smoking and chewing habits (TBSCH) on the oxidative stress biomarker levels, namely malondialdehyde (MDA), and the mucosal genotoxic nuclear damage in the marginal gingival cells of subjects. Furthermore, the correlation of the biomarkers, MDA, and nuclear changes in the form of micronucleation (Mn) and binucleation (Bn) was investigated. MATERIALS AND METHODS: Forty study participants were divided into five subject categories, which were established based on the presence of periodontitis, DM, and TBSCH. Whole saliva and marginal gingival smears collected from subjects were used to determine MDA levels and nuclear changes, respectively. A full-mouth assessment of periodontal pocket depth, clinical attachment loss, and bleeding on probing was performed for each subject to determine periodontal status. RESULTS: MDA and Mn levels between control group and subjects with only periodontitis (MDA: P < 0.9990; Mn: P < 0.8200) showed no significant difference, whereas levels among subjects with DM, TBSCH, and periodontitis, and all other categories were statistically significant (MDA: P < 0.001). DM and/or TBSCH superimposed on periodontitis cause an exponential increase in biomarker levels. Furthermore, MDA and Mn showed poor correlation (r = 0.162; P = 0.318). Periodontitis alone did not significantly increase oxidative stress levels compared to healthy controls, whereas DM and TBSCH resulted in augmented oxidative stress levels, implying that increased stress produced by DM and TBSCH aggravates or exaggerates periodontal inflammation. CONCLUSION: Poor correlation between MDA and Mn indicated that the mechanisms involved in their production are independent of each other.

Assessment and comparison of nuclear changes seen in gingivitis and periodontitis using fluorescent microscopy / Valoración y comparación de los cambios nucleares observados en gingivitis y periodontitis, mediante microscopio fluorescente

INTRODUCTION AND OBJECTIVES: The objective of this study was to observe the evolution of genotoxicity (micronucleation, binucleation and multinucleation) from normal to periodontally compromised gingival epithelium (gingivitis and periodontitis) and to compare the severity of damage. METHODS AND MATERIAL: 45 participants formed 3 different categories; a control group of 15 healthy subjects, 15 subjects with gingivitis and 15 with chronic periodontitis. Smears were collected from all the gingiva and stained with acridine orange stain. A total of 500 cells were evaluated under fluorescent microscopy for nuclear abnormalities such as micronuclei, binucleation and multinucleation. The statistical analysis used was one way ANOVA and posthoc Tukey test. RESULTS AND CONCLUSIONS: A statistically significant difference was observed when the age of the 3 groups were compared (p = 0.002); the control group were younger than those with chronic periodontitis or gingivitis. With respect to genotoxic changes, the differences for binucleation (p = 0.002) and multinucleation (p < 0.001) were statistically significant thus suggesting advanced damage in the nucleus. Such changes in genotoxicity could be of help to a clinician in determining prognosis

INTRODUCCIÓN Y OBJETIVOS: El objetivo de este estudio fue observar las tendencias en cuanto a genotoxicidad (micronucleación, binucleación y multinucleación) a partir de epitelio gingival de normal a periodoncialmente-comprometido (gingivitis y periodontitis), y comparar la gravedad del daño entre ambas situaciones. MÉTODOS Y MATERIAL: Seleccionamos a cuarenta y cinco sujetos, que agrupamos en 3 categorías (15 sujetos sanos, 15 con gingivitis y 15 con periodontitis crónica). Se recogieron frotis del tejido gingival de dichos sujetos, que se tiñeron con acridina naranja. Evaluamos un total de 500 células bajo el microscopio fluorescente en busca de anomalías nucleares de tipo micronúcleos, binucleación y multinucleación. El análisis estadístico utilizado fue ANOVA unidireccional y Tukey posthoc. RESULTADOS Y CONCLUSIÓN: Observamos una diferencia estadísticamente significativa al comparar los 3 grupos de edad (p = 0,002), donde el grupo control (sujetos sanos) pertenecía a un rango de edad inferior a los sujetos con periodontitis o gingivitis crónicas. Con respecto a los cambios genotóxicos, las diferencias para binucleación (p = 0,002) y multinucleación (p < 0,001) fueron estadísticamente significativas, lo cual sugiere un daño avanzado en el núcleo. Las tendencias en cuanto a genotoxicidad podrían ayudar a los clínicos a determinar el pronóstico de la enfermedad

Towards a Common Etiopathogenesis: Periodontal Disease and Endometriosis.

CONTEXT: Periodontal disease and endometriosis are seen to share a common pathogenesis. There is only one report suggesting the possible association between the two conditions. AIMS: To study the association between endometriosis and periodontal disease. SETTINGS AND DESIGN: This was a case-control study. SUBJECTS AND METHODS: Periodontal screening was carried out in 25 women with endometriosis and 25 women without endometriosis. Severity of periodontal disease was classified based on the extent of loss of attachment. STATISTICAL ANALYSIS USED: Student's t-test, Mann-Whitney U test, and Karl Pearson correlation coefficient tests were used for statistical analysis. Results: The proportion of women with severe periodontitis was seen to be higher among women with endometriosis (70%). CONCLUSIONS: The results of the present study indicate the existence of a relationship between endometriosis and periodontal disease. However, further studies among larger cohorts of endometriosis may provide evidence about the association.

Concept of Minimally Invasive Indirect Veneers.

Minimally invasive indirect veneers (MIIV) are ultrathin porcelain veneers that can be cemented onto labial surfaces after no or minimal tooth preparation. The benefits of no or minimal veneer preparation are conservation of tooth structure, absence of postoperative sensitivity, bonding to enamel, minimal flexural stresses, no need for provisionals and improved patient acceptance. However, no or minimal preparation veneers should be considered only after thorough functional and aesthetic evaluation. The article presented here illustrates a case of diastema closure using MIIV, to highlight the importance of treatment planning for achieving good results.

Periodontal disease and pregnancy hypertension: a clinical correlation.

BACKGROUND: Periodontal disease is thought to be associated with increased risk of systemic diseases and adverse pregnancy outcomes, including pregnancy hypertension (PH). The aim of the present study is to find the prevalence of periodontal disease in females with PH in a rural-based medical institute. METHODS: The present case control study was performed with 200 females, 100 with PH and 100 without PH. Antenatal periodontal screening was performed within 72 hours of their hospital admission for delivery. The periodontal parameters assessed were oral hygiene index-simplified, gingival index, mean probing depth, and loss of attachment. RESULTS: Prevalence of periodontal disease was 65.5% and was significantly higher (P <0.0001) in females with hypertension (relative risk = 1.5; 95% confidence interval [CI] = 1.3 to 1.9). Socioeconomic status, education, occupation, and body mass index did not appear to influence the relationship between periodontal disease and PH on bivariate multiple logistic regression analysis. Nulliparous females were at higher odds to develop periodontal disease and PH (odds ratio = 1.7; 95% CI = 0.5 to 6.1). As the severity of periodontal disease increased from moderate to severe, the severity of hypertension also increased (r(2) = 0.8 and 0.5 for moderate and severe periodontal disease, respectively). CONCLUSION: Periodontal disease is more prevalent in females with PH.
