Clinical and biological evaluation of one-step procedure covering of exposed surfaces of root with connective tissue free graft by envelope method and applying Citric Acid

A. Miremadi

Normal 0 false false false EN-US X-NONE AR-SA In present study, 12 patents (10 F/2M) of 19-42 years with gingival recession in 14 sites of the mouth were recruited. Inclusion criteria were considered and following primary treatments, measurements (sulcus depth as well as depth and width of gingival recession and distance between a fixed point and gingival margin ) were done. Free gingival graft from palate was harvested by envelope technique and using saturated citric acid. The distance between a fixed point and gingival margin and sulcus depth were recorded after 1,2,3,6 month post surgery. In addition, The depth of gingival recession from CEJ was measured 6 month post operatively. Based on tables and statistical methods, the root coverage was 65.35%. by 3 weeks after surgery, the graft was united with the adjacent tissues.

Evaluating the role levers in Occlusion

Normal 0 false false false EN-US X-NONE AR-SA Lever is a solid part that can turn on a fulcrum. There are three types of fulcrums. The efficacy of a lever system is measured by mechanical advantage. The first type of lever has the most and third type has the least mechanical advantage. The situation of muscles attachments and direction of forces on teeth in mandible is similar to lever type 3 and therefore, the muscles, bones and teeth can bear occlusal forces. If a destructing contact develops, this lever system will change and cause damaging effects on stomatognathic structures.

Comparing the distribution of tension in mesial and distal rests in abutment teeth adjacent to free end partial removable dentures in movements toward tissue

F. Gerami Panah

Normal 0 false false false EN-US X-NONE AR-SA In this research, by using limited elements, distribution of tensions in mesial and distal rests on root surfaces of abutment teeth of removable partial dentures was studied. First mandibular premolar was divided into 48 triangular elements. mastication force and thickness of covering tissue were considered 30 pounds and 2.5 mm respectively. During the movements toward the tissue, the tension on abutment teeth with mesial rests was lower and more uniform in comparison to distal rests.

Clinically evaluating the effect of Bass and Rolling methods on ginigival and plaque indices in 16-17 years students of Tohid school in Shiraz

Normal 0 false false false EN-US X-NONE AR-SA In this study, 30 boy students of 16-17 years were randomly selected and were allocated into three groups: The control group, Bass group in which the members were instructed to brush their teeth with Bass method and Rolling method group in which they were asked to brush with Rolling Method. Two latter groups brushed their teeth two times a day (morning/night) .for all the participants, ultrasonic scaling was done 4 weeks prior to the study. After 4 weeks, PLI and GI were measured and recorded by Sillness and Loe method. All the participants used a soft multitufted tooth brush. All 3 groups showed lower indices in comparison to basle line measurements but Two latter groups showed higher difference in comparison to the control group.The difference between Second and third groups was not found statistically significant. Gingival index during 4 weeks of study has not changed siginificantly.The obtained results confirmed the importance of duration and quality of every brushing technique.

Evaluating the effect of chlorhexidine mouthwash 0.2% in controlling the oral complications of chemotherapy

Normal 0 false false false EN-US X-NONE AR-SA In order to evaluate the effect of chlorhexidine mouthwash in controlling oral complications of chemotherapy, 146 patients were recruited among the patients referred to heamatology department of Shariati hospital who were under treatment by routine chemotherapic drugs like EBDV, CMF or FU-Lucoverin5 for first, second or third time. The patients were allocated into two groups to receive either chlorhexidine or Placebo for a week after careful examination and evaluation. Finally, It was concluded that Chlorhexidine is effective to reduce oral complications of chemotherapy (P-value≤0.002).

Evaluating the average space between Distal and middle of incisive papilla and left maxillary central tooth

Normal 0 false false false EN-US X-NONE AR-SA 60 dental students were randomly selected to obtain upper and lower jaw impressions. After excluding some non-classic cases, 50 mandibular and maxillary casts ( 34 M/16F) have been prepared for studying. Measuring was done via Boly Dial Guage collis attached to the vertical part of a surveyor. Posterior and middle border of incisive papillae in each cast was identified via stereomicroscope .The space between most prominent surface of left maxillary central teeth and Distal and middle of incisive papillae were measured. The average measures were 11.570 and 8.721 respectively.

Clinical evaluation of the incidence of premature contacts and related complications and complaints

A. Khavari

Normal 0 false false false EN-US X-NONE AR-SA The term "Premature contact" in dentistry and especially in Orthodontics represents sudden contact of a point in one or more teeth with an area of one or more opposing teeth in occlusion or during articulation prior to any contact between the other teeth. These teeth are generally bearing imbalanced and undesirable pressures that make them prone to complications .The wide range of lesions can be manifested as local and centralized or scattered and referral that can damage adjacent organs. As premature contact is a damaging factor that can lead to dentomandibular disorders, it is essential to be followed carefully. In a research on 93 patients selected from 228 of private office referral patients, points were found that consequently led us to a better introduction to this problematic Factor.

Facial Bone fractures: a 9 year survey

MH. Ansari

Normal 0 false false false EN-US X-NONE AR-SA To divide the face into three parts, the "upper face" is located superior to the zygomaticofrontal and frontonasal and maxillonasal sutures. "Mid face" is between those sutures in upper limit and incisal edge of maxillary teeth in lower limit (for edentulous patients, alveolar process of maxilla is considered instead). Mandibular bone which is basically a long-tubular bone forms"lower Face".
