Evaluation of Serum Interleukin-33 Level in Iraqi Patients with and without Periodontal Disease.

Objective: Periodontitis is a multifactorial inflammatory illness characterized by periodic tissue support deterioration. Interleukin-33 has recently been discovered as a new pro-inflammatory cytokine implicated in the pathogenesis of periodontitis. The objective of this case control study is to compare IL-33 levels among periodontitis patients and healthy volunteers using serum samples and investigate the potential association with clinical periodontal parameters. Materials and Methods: A total of 100 subjects (50 patients with periodontal disease and 50 healthy individuals) were included in this case control study. Clinical plaque index (PLI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment loss (CAL) were assessed. Serum was extracted from the venous blood that was collected. Serum IL-33 values were measured using an enzyme-linked immunosorbent assay (ELISA). Results: Serum levels of interleukin-33 showed considerably elevated level in the patient's group than in the healthy control group (P<0.01). There was a strong correlation between the blood levels of IL-33 and PLI, GI, and BOP (P≤ 0.05). While PPD and CAL demonstrated a non-significant relationship (P˃0.05). Conclusion:  The results of this study suggested that IL-33 may be used as a potential indicator of the inflammation associated with periodontitis and might have a role in the development of the disease. Further studies with large sample sizes are needed to improve knowledge about the role of IL-33 in periodontal health and disease. Clinical Significance: Owing to the noticeable role that IL-33 plays in the pathogenicity of periodontitis as a local waring clue for the periodontal tissue breakdown, tissue-specific therapeutic strategies may improve.

The impact of traditional smokers versus electronic cigarette smokers on periodontal parameters in iraqi males / O impacto do uso de cigarros tradicionais versus uso de cigarros eletrônicos nos parâmetros periodontais em homens iraquianos

Objective: To compare the effects of vaping and cigarette smoking and indicate their impact on periodontal health. Material and Methods: A total of 90 subjects divided into three groups. Group I: 30 Traditional cigarettes smoker who have smoked up to 10 cigarettes, Group II: 30 electronic cigarettes subjects who have been using vape at least one year and never smoke, and Group III: 30 subjects who have no smoking history. Using a mirror and a periodontal probe, periodontal parameters (plaque index, gingival index, probing depth and clinical attachment loss) were used to evaluate periodontal health. Results: The findings showed that the periodontal parameters had a highly significant differences at P ≤ 0.01 between traditional and electronic smoking groups. While clinical attachment loss demonstrated non-significant difference P ≥ 0.05 in comparison between electronic cigarettes and the group who never smoke. Conclusion: The results of this study suggested that traditional cigarettes and electronic cigarettes both had unfavorable impact on periodontal health status, never the less quit smoking showed positive impacts on periodontal parameters (AU)

Objetivo: O objetivo foi comparar os efeitos do uso do cigarro eletrônico e do cigarro convencional, indicando seus impactos na saúde bucal. Material e Método: 90 indivíduos foram divididos igualmente em três grupos: Grupo I, usuários de cigarro convencional que fumaram até 10 cigarros por dia; Grupo II: usuários de cigarro eletrônico que utilizam este por pelo menos há 1 ano e não fumavam antes disso; Grupo III: usuários sem qualquer história de hábitos tabagistas. Utilizando um espelho bucal e uma sonda periodontal, parâmetros periodontais (índice de placa, índice gengival, profundidade de sondagem e perda de inserção clínica) foram coletados para avaliar a saúde periodontal. Resultados: As evidências mostraram que os parâmetros periodontais apresentaram diferença significativa (P ≤ 0.01) entre os grupos I e II. Conclusão: Os resultados deste estudo sugerem que tanto o uso de cigarro convencional como o de cigarro eletrônico possuem impactos desfavoráveis na saúde periodontal, e que a cessação do uso destes mostraram impactos positivos nos parâmetros periodontais(AU)

Referral pattern of periodontal disease among general dental practitioners in Iraq / Padrão de referência da doença periodontal entre os clínicos odontológicos gerais no Iraque

Objectives: To evaluate the type of "periodontal treatment" performed by general dental practitioners and the referral patterns of periodontists in Iraq. Material and methods: A total of 201 general dentists were asked to complete a self-administered questionnaire consisting of nine questions regarding periodontal treatment and the referral patterns of periodontists. Results: The study showed that 91.1% of general dental practitioners (GDPs) performed "phase-I therapy", and most of them done "scaling". Regarding surgical periodontal therapy, only 12.9% of them performed surgical periodontal therapy, half of the GDPs did gingivectomy, and less than 30% performed crown lengthening. When evaluating maintenance therapy after periodontal treatment, it was found that 77.9% of the GDPs scheduled appointments for patients in the maintenance phase, 49.4% of them after one month, 24.7% after three months, and 15.6% after six months. Using TRUF analysis, most general dentists believed that the patient and periodontal factors were responsible for the recurrence of periodontal disease. Conclusions: There is still a lack of awareness of periodontal surgical procedures among the "general dental practitioners". Thus, it is essential to increase the comprehension of periodontal treatment among general dentists. (AU)

Objetivo: Avaliar o tipo de "tratamento periodontal" realizado por dentistas generalistas e os padrões de encaminhamento aos periodontistas, no Iraque. Material e métodos: Um total de 201 dentistas generalistas preencheram um questionário autoaplicável que consistiu em nove perguntas sobre o tratamento periodontal e os padrões de encaminhamento para periodontistas. Resultados: O estudo mostrou que 91,1% dos dentistas gerais (DG) realizavam "terapia fase I" e a maioria realizava "raspagem". Em relação à terapia periodontal cirúrgica, apenas 12,9% deles realizavam, sendo que metade dos DG realizavam gengivectomia e menos de 30% realizavam aumento de coroa clínica. Ao avaliar a terapia de manutenção após o tratamento periodontal, constatou-se que 77,9% dos DGs agendaram consultas para pacientes em fase de manutenção, sendo 49,4% após um mês, 24,7% após três meses e 15,6% após seis meses. Usando a análise TRUF, a maioria dos dentistas gerais acredita que o paciente e os fatores periodontais são responsáveis pela recorrência da doença periodontal. Conclusões: Ainda existe um desconhecimento dos procedimentos cirúrgicos periodontais entre os "dentistas generalistas". Assim, é essencial aumentar a compreensão do tratamento periodontal entre os cirurgiões-dentistas gerais (AU)
