RESUMEN
Statement of the Problem: Trichomonas tenax and Entamoeba gingivalis are commensal protozoa which inhabit the human oral cavity. These parasites are found in patients with poor oral hygiene and might be a reason for progressive periodontal diseases
Purpose: The aim of this study was to evaluate the effect of nonsurgical periodontal treatment on the frequency of these protozoa in saliva and plaque samples
Materials and Method: In this clinical trial, samples of saliva and dental plaque were collected from 46 patients with moderate to severe chronic periodontitis before and after periodontal therapy. The samples were assessed for the frequency of parasites
Results: The frequency of Entamoeba gingivalis was reduced in saliva [p= 0.007] and plaque [p= 0.027] three weeks after the treatment. Likewise, the frequency of Trichomonas tenax reduced in saliva [p= 0.030]; however, the decrease was not significant in plaque [p= 0.913]. Trichomonas tenax frequency in dental plaque directly related to the severity of periodontitis [r= 0.565, p
Conclusion: Nonsurgical periodontal treatment could reduce the number of Trichomonas Tenax and Entamoeba gingivalis in the oral environment of patients with chronic periodontitis
RESUMEN
Statement of the Problem: Phenytoin [PHT] has been known to promote wound healing in some medical conditions owing to its proliferative as well as anti-inflammatory effects. Yet, its application in oral lesions was less investigated
Purpose: The aim of this study was to evaluate changes in periodontal indices following the topical use of phenytoin in chronic periodontitis
Materials and Method: In this doubled-blind, randomized, split-mouth controlled clinical study, 20 patients with moderate to severe chronic periodontitis referred to Periodontology Department of Shahid Sadoughi Medical University of Yazd in 2014 were selected consecutively. After initial therapy [scaling and root planning and oral hygiene instructions], periodontal indices including bleeding on probing [BOP], periodontal pocket depth [PPD] and modified gingival index [MGI] were recorded. Gingival facial surface of two posterior sextants with at least two teeth with similar conditions, were selected randomly. Then one surface received PHT paste whereas the other side had placebo as control. Patients were received the mucoadhesive pastes under strict control by an examiner, twice a day for a week. Periodontal indices were measured 3 weeks after treatment. Data was analyzed with t-test and paired t-test by using SPSS 21 software
Results: It was observed that periodontal pocket depth was significantly more decreased in phenytoin side in comparison with placebo one [p< 0.05]. In addition, inflammatory indices including bleeding on probing and modified gingival index declined more in the phenytoin group [p= 0.001 and p< 0.05 respectively]
Conclusion: These encouraging results support the use of 1% phenytoin mucoadhesive paste as an adjunctive in periodontal treatment
RESUMEN
There have been speculations about the effects of hormonal changes and socio-demographic factors on periodontal health during pregnancy. According to the lack of sufficient epidemiologic information about the periodontal status of pregnant women in Yazd, this study was accomplished to determine the changes of Community Periodontal Index for Treatment Needs [CPITN] during pregnancy and evaluating the possible relationship between this index and demographic characteristics of the mothers. This was a longitudinal descriptive study. The samples included 115 pregnant women who were referred to health centers of Yazd, Iran. The mothers' data were obtained from a questionnaire consisted of 3 parts: consent paper, demographic data and CPITN records. Examination was performed with dental unit light, flat dental mirror and WHO's scaled probe. In the beginning of the study, 60.1% of checked sextants had healthy gingival status. 25.9% had code1 and 14% had code 2. Code 3 and 4 were not seen in any sextants. There was a significant relationship between lower CPITN and higher maternal education, occupation and more frequencies of tooth-brushing but there was not a relationship between CPITN and mother's age and number of pregnancies. CPITN had a significant relationship with increasing of the gestational age. There might be a relationship between increasing the month of pregnancy and more periodontal treatment needs. CPITN Increasing during pregnancy shows the importance of periodontal cares during this period
