ND YAG laser-assisted periodontal practice

Periodontal treatment modalities have advanced steps with implementation of LASER therapy. When the LASER used clinically in treating periodontal diseases it offers the clinician many advantages. This paper discussed the features of Nd: YAT wave length using 800 ND YAG pulsed LASER in treating different periodontal cases with the advantages of an optic fiber delivery system

prevalence of localized juvenile periodontitis in a selected Saudi population: sex ratio in association with recovery of actinobacillus actinomycetemcomitans

The rationale of this study was to determine the prevalence and sex ratio oflocalized juvenile periodontitis cases in selected Saudi population and tocompare these values with different societies and to correlate the sex ratiowith the presence of Actinomyces actinomycetemcomitans in the afflicted sites. 23 subjects of LJP were diagnosed from a group of 5480 subjects havingdifferent forms of periodontal diseases in a three year retrospective study. The overall prevalence was 0.42% female to male ratio 1.88 to 1. Nostatistically significant difference was noticed in the sex ratio associationregarding the sites afflicted by Actinomyces actinomycetemcomitans

Reliability of crevicular fluid measurements taken in the presence of short fasting during healing following flap surgery

This study examined the influence of short Ramadan fasting on the gingivalcrevicular fluid flow taken following flap surgery. Thirty modified Widman flapsurgeries were performed in 15 male patients in a split mouth design within aperiod of 3 years. Fifteen surgeries were performed in the tested sidesduring Ramadan fasting state, the other ones performed in the contralateral"controlled" sides after Ramadan. GCF was collected on filter paper stripswhich were placed subgingivally on the surgical gingival sites. The quantityof GCF was determined preoperatively, by ninhydrin staining method. Plaqueand gingival indices were correlated with GCF flow rate at each examinationperiod. The result showed that there was a direct increase in GCFmeasurements after surgery in both sides. The mean difference between themwas relatively low. In the second week of evaluation period, there was amarked decrease in GCF flow rate in the tested sides than to the controlledones. Highly significant difference was found statistically between them t=8.84 P <0.05. In the fourth postoperative week, no significant difference wasdetected between both sides t= 1.28 P >0.05. Clinical parameters of plaqueand gingival indices showed no significant difference between both sidesthrough all examination periods

Clinical applicability of guided tissue regeneration in the treatment of class II furcation involvement: observation in Saudi treated cases

This investigation assessed the clinical efficacy of guided tissueregeneration [GTR] procedures using polytetrafluoroethylene membrane [Goretex]in the treatment of glass II furcation involvement. Nine Saudi subjects with12 furcal defects comprised this study. Following the completion of ahygienic phase of treatment, measurements were made with calibratedperiodontal probe to determine the clinical parameters of recession, probingdepth and attachment level. Flaps specific for guided tissue regenerationwere done for exposing the furcal defects. Curettage and root planning fordebridement of the defects were performed and the membranes were applied andsutured. Membranes were removed at 4 to 6 weeks. The parameters wereassessed and compared at 3 and 6 months of postmembrane retrieval. After 3months, there were statistically significant differences in all parametersfrom the baseline data. At six months, there were statistically significantdifferences in probing depth and attachment level. No statisticallysignificant differences were found in recession. When the parameters at 3,and 6 months were compared, no statistically significant difference wasobserved. GTR procedures using Goretex membranes could be considered as agood therapeutic modality for class II furcation defects

Human clinical and histological responses of tricalcuim phosphate sodium fusidate alloplast mixture in fifteen intrabony defects

Fifteen intrabony defects in ten volunteer subjects were monitored clinically and histologically after filling with tricalcium phosphate sodium fusidate mixture. The purpose of the study was to test the particle mixture ability in regenerating osseous defects and to assess the bioacceptability of the mixture in human bone and soft tissues. Clinical results showed a reduction of average probing depth of 3.8 mm and an average gain in attachment level of 1.74 mm in comparison to pre-surgical status. Re-entery data showed that the graft mixture resulted in 60 percent overall defect fill. Histological responses of the implant sites showed that the mixture was well tolerated by the tissues and the material was in a process of degradation. Presented data indicate that the mixture could be helpful in facilitating regeneration of periodontal intrabony defects

Mixed dentition concerning the measurement of attached gingiva and gingival sulcus-clinical study

This study have been done on 100 children from the Egyptian primary school, their ages ranged from 6-10 years. Clinical examination, measuring the width of the attached gingiva and depth of gingival sulculs have been done. We conclude that attached gingiva is a keratinized tissue designed to withstand the daily frictional forces. In mixed dentition, when the permanent teeth erupt they have the tendency to increase the width of the attached gingiva and decrease the sulcus-depth with age. Both periodontist and pedodontist are in a position to perform a diagnostic and preventive service to these patients by observing the mucogingival problems that can be seen
