Background: chronic Periodontitis is considered to be an inflammatory disease and is characterized by the damaging the connective tissue and supporting bone due to secondary infection by periodontal bacteria. Chlorhexidine has been used in the dental practice as an excellent antiplaque agent. Chlorhexidine not only exhibits special property of substantivity, it also possesses a broad antimicrobial spectrum which makes its use in wide variety of oral disorders. Virtually all disciplines of dentistry make use of this material in different formulations like mouth wash, gel, spray, varnish, and restorative material.
Aims of study: The aim of this study was to evaluate the clinical effectiveness of locally delivered Chlorhexidine gel as an adjunctive therapy to scaling and root planing in treatment of chronic periodontitis.
Material and methods: five patients with chronic periodontitis were selected. Pocket depth between 4 and 6 mm was selected and the patient had two sites on his mouth (splitting mouth). A total of 17 control sites were scaled and root planed and 17 test sites were scaled and root planed and Chlorhexidine gel was added. The clinical parameters, probing depth (PD), clinical attachment level (CAL), plaque index (PI) and bleeding on probing (BOP), gingival index were recorded at baseline, 1 week, 2 weeks and 4 weeks.
Results: From baseline to a period of 4 weeks, significant difference was found between test and control group for PD, CAL, PI and BOP.
Conclusions: Subgingival injection of Chlorhexidine gel adjunct with scaling and root planing appeared to cause significant improvement compared with scaling and root planing alone in persons with chronic periodontitis.

ABSTRACT : This study was aimed to compare the clinical effectiveness of ozonated gel and chlorhexidine treatments on gingival crevicular fluid (GCF) volume associated with plaque-induced gingivitis (PIG). Fifty male patients affected with (PIG), (25/group) with an average age of (18-30) years were enrolled throughout the study. They were divided into two groups, (G1) scaling and treated with Chlorhexidine and (G2) scaling and treated with Ozone gel. Patients were instructed to massage their gingiva twice a day for 1 week with the ozonated gel). GCF was collected from four sampling tooth sites by paper strips (PS) at zero-time and day-7. The median values of the GCF volume (µL) at 0-time showed that there were no statistically significant differences among the two groups. However, at day-7 post-treatments Ozone gel group showed significantly lower GCF volume. Treatment for 7 days with Ozone gel was much more efficient in reducing GCF volume (µl) when compared with the Chlorhexidine group

aBackground:

D

iabetes and periodontitis

are

considered as chronic diseases with a bidirectional relationship between them.

This study aimed t

o determine and compare the severity

of periodontal

health status and

salivary parameters in

diabetic and

non

-

diabetic

patients

with chronic periodontitis

.

Materials and M

ethods

: Seventy

p

articipants were enrolled in this

stud

y

.

The subjects were divided into three

groups:

Group

I: 25 patients

had

type 2 diabetes mellitus with chronic periodontitis

,

Group 2: 25 patients

had

chronic periodontitis and with

no

history of any systemic diseases

,

Group 3: 20 subjects

had

healthy periodontium and

were

systemically

healthy.

Unstimulated whole saliva was collected for measurement of salivary flow

rate and

pH. All periodontal parameters (plaque

index, gingival

index, probing

pocket depth and clinical attachment level

)

were recorded for

each

patient

.

Result

s

:

The results showed that all clinical periodontal parameters we

re highest in group 1 in comparison wi

Conclusion

:

Type 2 diabetic patients

have significantly lower salivary flow rate, pH and present with advanced
