The prevalence and predictive factors of dentine hypersensitivity among adults in Turkey.

AIM: This study sought to determine the prevalence of dentine hypersensitivity (DH) among adults in Turkey. Also, to ascertain the association between DH and both etiological predictors and demographic patient characteristics. MATERIAL METHOD: Using a questionnaire and thermal and evaporative tests, 259 women and 209 men in the age range of 18 to 72 were analyzed. Individually, a clinical evaluation of DH signs was conducted. The DMFT index, gingival index, and gingival bleeding were reported for each subject. The gingival recession and tooth wear of sensitive teeth were also evaluated. Pearson Chi-square test was used to compare categorical data. Logistic Regression Analysis was used to examine the risk factors of DH. Data with dependent categorical variables were compared using the McNemar-Browker test. The significance level was p < 0.05. RESULTS: The average age of the population was 35.6 years. In the present study, a total of 12,048 teeth were analyzed. 1755 had thermal hypersensitivity (14.57%), while 470 experienced evaporative hypersensitivity (3.9%). The incisors were the teeth most impacted by DH, whereas the molars were the least affected. Exposure to cold air and sweet foods, gingival recession, and the presence of noncarious cervical lesions were all strongly linked to DH (Logistic regression analysis, p < 0.05). The cold stimulus increases sensitivity more than the evaporation stimulus. CONCLUSION: Significant risk factors for both thermal and evaporative DH include cold air, consumption of sweet food, presence of noncarious cervical lesions, and gingival recession. More epidemiological research in this area is still required to fully characterize the risk factors and implement the most effective preventive interventions.

Epidemiology of mid-buccal gingival recessions according to the 2018 Classification System in South America: Results from two population-based studies.

AIM: The aim of this investigation was to estimate the prevalence, severity and extent of mid-buccal gingival recessions (GRs; classified according to the 2018 Classification System) and to identify their risk indicators in the South American population. MATERIALS AND METHODS: Epidemiological data from two cross-sectional studies-performed on 1070 South American adolescents and 1456 Chilean adults-were obtained. All participants received a full-mouth periodontal examination by calibrated examiners. GR prevalence was defined as the presence of at least one mid-buccal GR ≥ 1 mm. GRs were also categorized into different recession types (RTs) according to the 2018 World Workshop Classification System. Analyses for RT risk indicators were also performed. All analyses were carried out at the participant level. RESULTS: The prevalence of mid-buccal GRs was 14.1% in South American adolescents and 90.9% in Chilean adults. In South American adolescents, the prevalence of RTs was 4.3% for RT1 GRs, 10.7% for RT2 GRs and 1.7% for RT3 GRs. In Chilean adults, the prevalence of RT1 GRs was 0.3%, while the prevalence of RT2 and RT3 GRs was 85.8% and 77.4%, respectively. Full-Mouth Bleeding Score (FMBS; <25%) was associated with the presence of RT1 GRs in adolescents. The risk indicators for RT2/RT3 GRs mainly overlapped with those for periodontitis. CONCLUSIONS: Mid-buccal GRs affected 14.1% of South American adolescents, whereas they affected most of the Chilean adult population (>90%). While RT1 GRs are more commonly observed in a non-representative cohort of South American adolescents (when compared to Chilean adults), the majority of Chilean adults exhibit RT2/RT3 GRs.

Patterns and predictors of periodontal disease and tooth loss among users of smokeless tobacco.

BACKGROUND: Smokeless tobacco (SLT) products of several different types are widely used in several South Asian countries including Pakistan. These products are consumed in different forms and with different names. The study aims to determine adverse effects of the SLT consumption on periodontal tissues. METHODS: This cross sectional study was conducted in Karachi, Pakistan. It recruited 377 users of (SLT) with 231 males (61.3%) and 146 females (38.7%) of age 15 to 45 years. After obtaining informed consent, quantitative data were collected via a questionnaire followed by intra oral clinical examination to determine presence of periodontal diseases using community periodontal index (CPI). To determine the association between periodontal diseases and smokeless tobacco consumption habits, Chi Square test was conducted. RESULTS: Gingival recession (Class II-IV) (65.8%) was the most prevalent periodontal disease among SLT users. CPI score was high (CPI score 3 and 4) in 31.3% participants, whereas tooth loss was found in 21%. Among types of SLT products, gutka (28.6%) and betel quid (23.3%) were most commonly used. Using SLT for five or more years was found to be associated with a high CPI score, gingival recession (Class II-IV), moderate to severe tooth mobility, and presence of tooth loss. CONCLUSIONS: The study found statistically significant association between duration in years of using SLT and periodontal disease including gingival recession, tooth mobility and tooth loss. However, no significant results were found between retention during single use and frequency of SLT use per day. However, the link of these factors with the periodontal disease cannot be eliminated.

Clinical investigation of gingival papilla recession after orthodontic treatment in adults.

OBJECTIVE: To investigate the incidence, severity, susceptibility sites of gingival papillary recession (GPR) in adults after orthodontic treatment and the clinical impact of tooth extraction on GPR. METHODS: A total of 82 adult patients were recruited and then divided into extraction and non-extraction groups according to whether the orthodontic teeth were extracted (teeth that needed to be extracted when performing orthodontic treatment). The gingival conditions of the two groups of patients before and after treatment were recorded using intraoral photos, and the incidence, severity and predilection sites of GPR after correction were investigated. RESULTS: The results indicated that GPR occurred in 29 patients after correction, with an incidence rate of 35.4%. A total of 1648 gingival papillae were recorded among the 82 patients after correction, of which 67 exhibited atrophy, with an incidence of 4.1%. All occurrences of GPR were classified as papilla presence index 2 (PPI 2) (mild). The condition is most likely to occur in the anterior tooth area, especially in the lower incisor area. The results indicated that the incidence of GPR was substantially higher in the extraction group than in the non-extraction group, with the difference statistically significant. CONCLUSION: Following orthodontic treatment, adult patients will have a certain proportion of mild GPR, which is more common in the anterior tooth area, especially the lower anterior tooth area.

Global prevalence of gingival recession: A systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to estimate the global prevalence of gingival recession (GR) in the general population. MATERIALS AND METHODS: Population-based observational studies reporting the prevalence of GR and published from 1991 to 2021 were identified from five electronic databases and manual searches. Risk of bias was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Studies. The pooled prevalence of GR was calculated by using a random-effect model. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to summarize the overall certainty of evidence. RESULTS: A total of 15 studies involving 37,460 participants were included. The overall pooled prevalence was 78.16% at the minimal reported threshold values and 84.92% at ≥1 mm "cut-off" with high heterogeneity among studies. A separate analysis for the buccal GR revealed a pooled prevalence of 75.42%. The risk of bias was found to be high for 10 and low for 5 studies. The overall certainty of the evidence was assessed to be very low. CONCLUSION: More than two-thirds of the population worldwide was found to be affected by GR. Studies with standard case definition and less heterogeneity are required to accurately estimate the prevalence of GR.

Prevalence of gingival recession and associated etiological factors among the school children.

Objective: The objective of this study is to assess the prevalence of gingival recession (GR) and associated etiological factors among school children. Methodology: The study sample consisted of 2095 children from the Nellore region divided into three groups of age ranges from primary dentition (<7 years), mixed dentition (7-12 years), and permanent dentition (>12 years) respectively, attending the department of pediatric and preventive dentistry and the school dental health programs organized by the department. The clinical examination involved measuring GR using William's periodontal probe and evaluating associated etiological factors. Data were statistically analyzed using the Chi-square test. Results: The GR among the study population was 7.9% (n = 165). Among them, males were 46% and females were 54% (P > 0.05). The GR was more in children in the 7-12 years age group (75%), followed by <7 years (21%) and >12 years (4%) age groups. The associated factors include malocclusion (69%), deleterious habits (5%), and anomalies (26%). Anomalies showed an association with GR (P < 0.05) compared to malocclusion and deleteriousness habits (P > 0.05). Conclusion: The prevalence of GR is 7.9%, and GR is more prevalent in males and the 7-12 years age group. GR is associated with transient malocclusion, deleterious habits, and anomalies.

Estimates and multivariable risk assessment of mid-buccal gingival recessions in an Italian adult population according to the 2018 World Workshop Classification System.

OBJECTIVES: The aim of this cross-sectional study was to provide estimate of mid-buccal gingival recession (GR) according to the 2018 World Workshop Classification System and to explore GR risk indicators in a representative urban population in North-West of Italy. MATERIAL AND METHODS: This is a secondary analysis using data collected in an epidemiological study enrolling a representative sample of 736 adults, living in Turin. GR prevalence was defined as the presence of at least one mid-buccal GR ≥ 1 mm. GRs were categorized according to the 2018 classification system (RT1, RT2, RT3) and to different severity cutoffs. Logistic regression analysis was performed to identify RT GR risk indicators. RESULTS: Mid-buccal GR ≥ 1 mm affected 57.20% of subjects and 14.56% of teeth. When considering RT1 GRs, their prevalence was 40.90% and 6.29% at the patient and tooth level. RT2 and RT3 GRs affected 25.82% and 36.68% of the study population, respectively. RT1 GRs occurred mostly on maxillary and mandibular premolars and maxillary canines, while RT2 and RT3 GRs on maxillary molars and mandibular incisors. Older age, high education, and full-mouth plaque score (FMPS) < 30% were risk indicators for RT1 GRs, while older age, poor education, periodontitis, and FMPS > 60% were significant contributors to RT2 and RT3 GRs. CONCLUSIONS: RT1 and RT3 are fairly common findings in this Italian population and are significantly associated to different contributing factors and tooth type distribution pattern. CLINICAL RELEVANCE: Prevention strategies should target different socio-demographic, behavioral, and clinical risk indicators based on the RT classes.

The prevalence, clinical features, and related factors of dentin hypersensitivity in the Turkish population.

OBJECTIVES: The purpose of this study was to identify the prevalence and predisposing and etiologic factors of dentin hypersensitivity (DH), as well as the demographic characteristics of patients. MATERIALS AND METHODS: The 1210 patients were examined. The research was based on a two-step investigation: questionnaire and clinical examination. DH was evaluated by the response of the patient to tactile and air-blast stimuli. Loss of attachment and gingival recession of sensitive teeth was measured on the buccal and lingual surfaces. Also, the tooth wear of sensitive teeth was graded on the buccal and lingual surfaces. Comparisons of nonnormally distributed continuous variables were performed using the Mann-Whitney U test and Kruskal-Wallis one-way analysis of variance (ANOVA) and Dunn's post hoc test. Comparisons of categorical variables were performed using Pearson's chi-square, Fisher's exact chi-square, Yates's chi-square, and the Monte Carlo chi-square test. RESULTS: One hundred twenty-four patients reported DH, showing a prevalence for self-reported DH of 10.2%. Eight hundred forty teeth were diagnosed as having DH, giving a clinical diagnosis rate of DH of 29.4%. Females (76.8%), the 31-40 years age group (26%), housewives (36.8%), and high school education level (38%) had the highest prevalence of DH as demographic properties. A cold stimulus was the most common stimuli trigger for hypersensitivity (97.1%). Occasional pain (55.5%) showed the highest prevalence in terms of frequency of DH. A higher rate of DH was found with the use of medium brushes (47.4%) and brushing twice per day (59.4%) for 1-2 min (56.2%) with the circular method (33.8%) as oral hygiene habits. The buccal surface of the lower right central incisors (5.7%) had the highest prevalence. The most affected teeth by DH were incisors (38.4%). The buccal surfaces (86.3%) of teeth showed a higher high prevalence of DH compared with the lingual surface (52.7%), similar to gingival recession (40.9% vs. 15.7%) and loss of attachment (68.3% vs. 42.6%). CONCLUSIONS: Clinically diagnosed DH was more common than self-reported DH. Some factors related to patients such as sex (female), the 31-40 years age group, housewives, high school students, using medium brushes, brushing twice per day, and the circular brushing method were more likely to have a risk for DH. Also, buccal surfaces of teeth, gingival recession, and loss of attachment on the buccal surface of teeth should be considered as predisposing factors for DH. CLINICAL RELEVANCE: To control and prevent DH, clinicians should consider patients' demographics, predisposing factors, and etiologic factors.

Incidence of Malocclusion among Young Patients with Gingival Recessions-A Cross-Sectional Observational Pilot Study.

Background and Objectives: Dental occlusion and gingival recession have been studied over the past years especially because of the increasing incidence of occlusal interferences in young patients. The purpose of this pilot study is to investigate any association between occlusal dysfunctions and gingival recessions. Data on gingival phenotype and previous orthodontic treatment were also collected to assess any correlation with the presence of gingival recession. Materials and Methods: Forty systemically healthy subjects, without signs of periodontitis and with gingival recessions, were included in the study. The following parameters were determined: location and extent of the gingival recession, gingival phenotype and functional occlusion by means of observing and registering the occlusal contacts in maximum intercuspation position, protrusive and lateral guidance. Results: Premolars were mostly affected in cases of working-side interferences during lateral guidance (71.19% of the affected teeth during left and 75% during right mandibular movements). The chi-squared exact test applied for the analysis of contingency tables revealed statistically significant associations between excursive interferences during lateral guidance and anterior guidance and the presence of gingival recession on the involved group of teeth. Conclusions: The results suggest that most gingival recessions might be associated with working-side interferences, the highest number of gingival recessions being associated with active interferences during lateral guidance.

Factores asociados al recubrimiento total de recesiones gingivales clases I y II de Miller / Factors associated to complete coverage of Miller class I and II gingival recessions

Introducción: La recesión gingival es uno de los defectos estético-funcionales más comunes en la cavidad oral. Se caracteriza por la exposición de la superficie de la raíz debido a un desplazamiento del margen gingival apical a la unión amelocementaria. La literatura reporta un porcentaje de recubrimiento de la raíz favorable en recesiones gingivales clases I y II de Miller; sin embargo, varios estudios no lograron el recubrimiento total, lo que ha sido asociado a varios factores. Objetivo: Identificar los factores asociados al recubrimiento total de recesiones gingivales clases I y II de Miller en dientes tratados con colgajo de reposición coronal. Métodos: Se consultaron las bases de datos PubMed SciELO, Redalyc, Lilacs y Scopus. De 105 investigaciones, se analizaron 7 que cumplieron los criterios de inclusión. Análisis e integración de las informaciones: El metaanálisis dio resultados no concluyentes, debido a la alta heterogeneidad de los estudios. Sin embargo, se detectaron los siguientes factores: el uso de ácido etilendiaminotetraacético (p < 0,0001), la presencia de tejido queratinizado adjunto ≥ 2 mm (p = 0,019), una profundidad de recesión gingival inicial > 3 mm (p = 0,020) y pacientes que fumaban más de 10 cigarrillos diarios (p < 0,05). Conclusiones: Se identificaron el uso de ácido etilendiaminotetracético, la presencia de tejido queratinizado, la profundidad de la recesión y pacientes fumadores como posibles factores que intervienen el recubrimiento total de recesiones gingivales clases I y II de Miller en dientes tratados con colgajo de reposición coronal(AU)

Introduction: Gingival recession is one of the most common esthetic-functional defects of the oral cavity. It is characterized by exposure of the root surface due to displacement of the apical gingival margin to the cementoenamel junction. The literature about the topic reports a percentage of favorable root coverage of Miller class I and II gingival recessions. However, several studies do not report complete coverage, which has been associated to a number of factors. Objective: Identify the factors associated to complete coverage of Miller class I and II gingival recessions in teeth treated with coronally repositioned flap. Methods: A search was conducted in the databases PubMed, SciELO, Redalyc, Lilacs and Scopus. Of a total 105 studies retrieved, seven met the inclusion criteria. Data analysis and integration: The meta-analysis did not achieve conclusive results, due to the high heterogeneity of the studies. However, the following factors were identified: use of ethylenediaminetetraacetic acid (p < 0.0001), presence of adjacent keratinized tissue ≥ 2 mm (p = 0.019), initial gingival recession depth > 3 mm (p = 0.020) and patients who smoked more than 10 cigarettes a day (p < 0.05). Conclusions: Use of ethylenediaminetetraacetic acid, presence of keratinized tissue, recession depth and smoker patients were identified as possible factors involved in the complete coverage Miller class I and II gingival recessions in teeth treated with coronally repositioned flap(AU)

Prevalance and clinical characteristics of gingival recession in Greek young adults: A cross-sectional study.

OBJECTIVE: The current cross-sectional study aimed to investigate the prevalence of gingival recession (REC) in a sample of young individuals. In addition, the association with several risk factors was examined. MATERIALS & METHODS: A 104 subjects, aged 18-30 years old, were randomly enrolled in the study. Participants were requested to fill in a simple structured questionnaire in order to provide information on dental hygiene habits, educational level, smoking and history of orthodontic treatment. Afterwards, all the included individuals were subjected to a thorough clinical periodontal examination including gingival recession (REC), gingival biotype, plaque levels and gingival bleeding index (GBI) assessment. RESULTS: The mean prevalence of REC in the studied population surpassed 50% with an equal distribution among females and males. The most common teeth associated with REC were the lower left canine and left 1st premolar. Among the examined variables, only the bleeding index was found to be associated with the presence of REC. CONCLUSIONS: Gingival recession was a prevalent condition among young individuals. Gingival inflammation was found to be the most significant factor affecting the incidence of REC.

Incidence and progression of gingival recession over 4 years: A population-based longitudinal study.

AIM: To describe changes in gingival recession (GR) at buccal and palatal sites in adults over an average follow-up of 4 years. MATERIALS AND METHODS: Baseline data were obtained from a multistage probabilistic representative sample of 1023 individuals aged ≥35 years from Porto Alegre, Brazil. Buccal and palatal/lingual GR were analysed. RESULTS: 402 individuals (6,862 teeth) were followed. At baseline, 3,356 (48.9%) teeth did not have GR at the buccal site and 1206 developed the condition overtime (incidence =35.9%; 95% CI 32.6-38.9). Percentage of incident teeth was higher among individuals with (42.3%) than those without (29.5%) periodontitis stages III/IV. Also, 38.5% of teeth with proximal attachment loss at follow-up had incident GR compared to 7.6% of those without proximal attachment loss. Incidence of palatal GR was observed in 32.5% of teeth (95% CI 29.7-35.3). Mean buccal and palatal/lingual GR incidence was 2.11 mm and 2.33 mm, whereas buccal and palatal/lingual GR progression equalled 0.40 mm and 0.48 mm. The prevalence of GR ≥3 mm increased in individuals with (from 35.9% to 47.4%) and without (from 25.2 to 41.5%) periodontitis. CONCLUSION: Incidence and progression of GR are high in a general urban Brazilian population of adults.

Epidemiology of mid-buccal gingival recessions in NHANES according to the 2018 World Workshop Classification System.

AIM: There are no nationally representative epidemiological studies available reporting on the different recession types according to the 2018 classification system or focusing on the aesthetic zone. The aims of this cross-sectional study were (a) to provide estimates on the prevalence, severity and extent of mid-buccal GRs according to the 2018 classification and (b) to identify their risk indicators in the adult U.S. population from the NHANES database. MATERIALS AND METHODS: Data from 10,676 subjects, representative of 143.8 millions of adults, were retrieved from the NHANES 2009-2014 database. GR prevalence was defined as the presence of at least one mid-buccal GR ≥1 mm. GRs were categorized following the 2018 World Workshop classification system (RT1, RT2, RT3) and according to different severity cut-offs. An analysis for GR risk indicators was also performed, selecting subjects without periodontitis. RESULTS: The patient-level prevalence of mid-buccal GRs (all types) was 91.6%, while it decreased to 70.7% when considering only the aesthetic zone. When focusing on RT1 GRs, the patient-level prevalence (whole mouth) was 12.4%, while it was 5.8% considering only the aesthetic zone. The majority of RT1 GRs were considered as mild (1-2 mm). The whole-mouth patient-level prevalence of RT2 and RT3 GRs was 88.8% and 55.0%, respectively. Age (35-49 years), gender (female), ethnicity (non-Hispanic Whites), last dental visit (>6 months before), tooth type (incisors) and the arch (mandible) resulted as risk indicators associated with the presence of RT1 GR. CONCLUSIONS: Mid-buccal GRs affect almost the entire US population. Age, gender, ethnicity, dental care exposure, tooth type and arch were identified as risk indicators for RT1 GRs.

Periodontal Risk Assessment Based on Dental and Gingival Morphology: A Comparative Analysis of African Versus Asian American Cohorts.

FOCUSED CLINICAL QUESTION: With the 2018 AAP/EFP disease classification with the staging and grading systems, does risk assessment for different ethnic group result in a different focus for clinical needs? This comparative analysis aimed to assess two previously reported cohort studies in African-American (Af-A) and Asian-American (As-A) as to the risk for these two populations for clinical attachment loss (CAL) and gingival phenotype. SUMMARY: In comparison of As-A and Af-A cohorts, As-A had higher frequency of thin tissue phenotype, less width of keratinized gingiva (KGW), and more gingival recession (GR). On other hands, Af-A showed higher prevalence of thick phenotype, longer total tooth length and root length (RL). These gingival and dental anatomical patterns suggest there are differential risk for GR, patterns for CAL, and periodontal prognosis between two cohorts. CONCLUSION(S): Because of nature of dental and gingival anatomy between these two cohorts, As-A are more susceptible in GR and the short RL affords this population less ability to withstand the clinical presentation of periodontal disease. From a therapeutic perspective, clinicians should evaluate patients with different risk assessment based on their dental and gingival characterization. Af-A may have clinical characteristics that makes this population less at risk for mucogingival defects. Conversely, phenotype modification therapy should be considered when treating As-A because of the high prevalence of thin tissue phenotype, inadequate KGW, and GR. Clinicians should also diligently monitor periodontal CAL around the teeth with shorter RL in periodontal or orthodontic therapy for better teeth prognosis.

Correlation of periodontal parameters to various types of smokeless tobacco in tobacco pouch keratosis patients: A cross-sectional study.

BACKGROUND: Tobacco practice in relation with oral diseases is a foremost cause for the global oral disease burden and is accountable for up to 50% of all periodontitis cases among adults. The present cross-sectional study was undertaken to evaluate the local effects of various types of smokeless tobacco on periodontal health in tobacco pouch keratosis (TPK) patients in Mangalore city in the state of Karnataka. MATERIALS AND METHODS: A total of 345 TPK patients were evaluated of which all were smokeless tobacco users. All the patients were clinically examined for different clinical periodontal parameters such as stains, gingival recession (GR), periodontal pocket, furcation involvement, and mobility and local effects of various types of smokeless tobacco on periodontal health in TPK sites were recorded. RESULTS: The prevalence of GR was of 87.5%. Haathichaap was the most common smokeless tobacco used (35.9%) closely followed by nonpackaged type (loose tobacco) (19.4%). This was followed by Madhu (14.2%). Likewise, periodontal parameters were observed more in these patients in decreasing order. CONCLUSION: The results of the present study agree strongly with other smokeless tobacco user studies in terms of the strong association between GR and smokeless tobacco placement. The present cross-sectional study indicates that TPK lesions are positively associated with periodontal diseases. It is important to raise awareness of both oral cancer and periodontal risks and inform about its possible health consequences thereby working towards an improvement of oral and general health and related quality of life in these patients.

Prevalence and risk indicators of gingival recessions in an Italian school of dentistry and dental hygiene: a cross-sectional study.

OBJECTIVES: The aim of this cross-sectional study is to (i) determine the prevalence, extent, severity, and distribution of gingival recessions and patient perception in a young population and (ii) to identify potential risk indicators. MATERIAL AND METHODS: Two hundred fifty-one students with a mean age of 22.9 ± 4.7, attending the School of Dentistry and Dental Hygiene of Vita-Salute San Raffaele University (Milan, Italy) were included. The subjects had undergone a clinical evaluation, by two calibrated examiner, and a questionnaire. Demographic and clinical data were collected to evaluate association of these factors with gingival recessions. RESULTS: The prevalence of gingival recessions at patient and tooth level was 39% and 5.2%, respectively. The only factor associated with the presence of GR was age. On the other hand, age and smoking were associated with the extent, whereas BOP, NCCLs and KT were associated with the severity. Out of 98 subjects presenting at least one GR, 63 (64%) were conscious of the presence of the GR. NCCLs were also strongly associated with the perception of the recession by the patient. CONCLUSIONS: There is a low prevalence of buccal gingival recessions in this sample of Italian students. More than 50% of the sample was aware of the problem. Almost all patients presenting symptomatology or aesthetic concern requested appropriate therapy. CLINICAL RELEVANCE: The findings highlight the low relevance of gingival recessions in daily practice and the importance of controlling potential risk indicators in young populations.

Association of Khat chewing, smoking, age and sex with periodontal status among Yemeni adults / Associação da mastigação de Khat, tabagismo, idade e gênero com a condição periodontal entre adultos iemenitas

Objective: Periodontal diseases are very common dental disease. Many risk factors may play significant role in the periodontal disease initiation and progression. This study was performed to evaluate the effects of khat chewing, smoking, age and gender on periodontal status among Yemeni adults. Material and Methods: This cross-sectional study was performed on 1231 patients attending the outpatient dental polyclinics of University of Science and Technology during the academic years 2017/2018. All completed sheets were collected throughout the year by the supervisors. Data cleaning, descriptive statistics, and inferential statistics were then performed. Results: Khat chewers were more frequent than non-chewers counterparts (60.7% vs. 39.3%). The prevalence of smoking was 25.5% (297 patients). Study results indicated that periodontitis is more associated with female gender and participants aged more than 35 years old. Results also showed that female and age older participants aged more than 35 years were significantly associated with gingival recession. Mean number of the teeth with gingival recession in male patients were higher than in females. Male gender and patients aged more than 35 years old were significantly associated with furcation involvement. Conclusion: The present study has shown females gender and age older than 35 seem to be risk factors of periodontal diseases. Males has more teeth affected by gingival recession and more furcation involvement (AU)

Objetivo: As doenças periodontais são patologias dentárias com alta prevalência. Diversos fatores de risco podem desempenhar papel significativo no início e progressão das doenças periodontais. Este estudo foi realizado para avaliar os efeitos da mastigação de khat, tabagismo, idade e gênero na condição periodontal de adultos iemenitas. Material e Métodos: Este estudo transversal foi realizado em 1231 pacientes atendidos nas policlínicas odontológicas ambulatoriais da Universidade de Ciência e Tecnologia durante os anos acadêmicos de 2017/2018 através de um questionário para coleta de dados préestabelecido.

Os resultados do estudo indicaram que a periodontite está mais associada ao gênero feminino e aos participantes com mais de 35 anos de idade. Os resultados também mostraram que participantes do gênero feminino e acima de 35 anos foram significativamente associadas à recessão gengival. O número médio de dentes com recessão gengival em pacientes do gênero masculino foi maior que no feminino. O gênero masculino e os pacientes com mais de 35 anos de idade foram significativamente associados ao envolvimento da furca. Conclusão: O presente estudo mostrou que o gênero feminino e a idade acima de 35 anos parecem ser fatores de risco para doenças periodontais. Pacientes do gênero masculino têm mais dentes afetados pela recessão gengival e mais envolvimento de furca.(AU)

Gingival Recession and Localized Aggressive Periodontitis Among HIV-infected Children and Adolescents Receiving Antiretroviral Therapy.

BACKGROUND: Limited information is available on gingival recession or localized aggressive periodontitis among HIV-infected children and adolescents. This study reports on the prevalence of these conditions among children and adolescents receiving antiretroviral therapy (ART). METHODS: A cross-sectional study on HIV-infected children and adolescents attending a Pediatric HIV clinic in Gauteng, South Africa, between January 2013 and June 2016. Patients received an oral examination and oral hygiene instructions, irrespective of oral- or dental-related complaints. Hard and soft tissue pathology was managed and recorded, together with relevant demographic and clinical data. Statistical analysis was performed in Stata 14 with P < 0.05 as significant. RESULTS: A total of 554 children and adolescents 5-19 years of age (median age: 12.2 years; interquartile range: 10.3-14.9) were included, of whom 78 (14.1%) presented with gingival recession on permanent mandibular incisors and/or localized aggressive periodontitis of molar teeth. Multivariable logistic regression revealed that patients with gingival recession and aggressive periodontitis had a significantly shorter duration of ART and were more likely to have suboptimal HIV control (CD4 count ≤500 cells/µL and/or HIV viral load ≥50 copies/mL) and be on advanced ART regimens after virologic failure on first- and second-line treatment. CONCLUSIONS: The results emphasize the importance of oral health care among HIV-infected children and adolescents from the onset, to prevent and manage conditions that could result in tooth loss and permanent disfigurement. This is of particular importance in the presence of virologic failure and immunosuppression.

Prevalence of gingival recession after orthodontic treatment of infraversion and open bite.

PURPOSE: Aim of the present study was to investigate the prevalence of gingival recession and related factors in teeth with low occlusal function (open bite and infraversion) after orthodontic treatment. METHODS: From January 2014 to December 2017, 403 patients received orthodontic treatment. Their gingival recession and related factors before and after treatment were retrospectively analyzed. RESULTS: The prevalence of gingival recession in patients with infraversion and open bite after orthodontic treatment were 80.6 and 75.0%, respectively; these values were 43.4 and 47.5% before treatment, respectively. Notably, the Miller index of gingival recession increased after orthodontic treatment (P < 0.05). The risk of gingival recession in patients with infraversion or open bite after orthodontic treatment was remarkably higher than the risk in other patients (odds ratio [OR] = 16.712 and 5.073, respectively); the gingival recession rate was related to treatment with tooth extraction (OR = 2.043), as well as gingival biotype (OR = 0.341) and gingival index (GI) before orthodontic treatment (OR = 97.404; P < 0.05). CONCLUSIONS: Patients with these two types of low occlusal function are more likely to exhibit gingival recession after orthodontic treatment. Moreover, the prevalence of gingival recession after orthodontic treatment is higher among patients who have undergone tooth extraction during orthodontic treatment, and among those who exhibit thin gingival biotype and high gingival index before orthodontic treatment.
