تتأثر تقنية قياس الأكسجة اللبية بكثير من العوامل، فالإشارات المستقبلة قد لا تدلُّ بالضرورة على الجريان اللبي وحده بل قد تختلط مع إشارات الجريان في الأنسجة اللثوية المجاورة أو الرباطية. لذا؛ أجريت هذه الدراسة السريرية بهدف تقييم تأثير عزل الأنسجة حول السنية عن التاج السني (باستخدام الحاجز المطاطي) في قياس قيم الأكسجة الدموية اللبية في الأرحاء المؤقتة.
Many factors affect dental pulp pulse oximetry technique (PO), as recipient signals may reflect not only pulpal blood flow, but also may mixed with signals of blood flow of the periodontal or gingival tissues. To evaluate the effect of isolation of the periodontal tissues apart from the dental crown using rubber dam; during pulpal blood oxygenation of the deciduous molars.

Anatomical features and color characteristics of teeth may affect the recipient
signals' nature during dental pulp oximetry, enamel tissue thickness may consider of the most important
factors. This clinical study aimd to evaluate the effect of enam
el tissue thickness of the upper premolar
crown on the accuracy of dental pulp oxygen saturation readings.
The results of this study indicate that there is a considerable effect of the dental tissue
thickness on the dental pulp oxygenation measurement. So; it is of important to find the suitable
adjustments on the PO apparatus, probe, or programs, in order to gain less effect of the anatomical
variances between teeth, and thus increasing pulse oximetry measurement accuracy.
When the caries become near the pulp in primary molars, the treatment will
be the pulpotomy to remove the involved coronal portion of the pulp, preserving the vitality and function
of the remaining radicular portion. Formocresol, Glutar-aldehyde, F
erric sulphate, AMT, Laser
application and Electro surgery may used in primary teeth pulpotomy.
Pulpectomy was performed on 100 primary teeth and the radiograph
was exposed immediately post treatment to observe weather the root
canal filling was: flush-undefiled or overfilled.
Teeth were examined periodically, clinically and radio graphically to
assess success of the treatment.
The objective of this study was to Compare between The Effect Of
secondary closure and Rubber Drain post surgical Extraction to
Impacted Lower Third Molars On edema, pain, and trismus level.
Clinical trial included symmetric bilateral 40 lower thi
rd molar in
20 patients whose ages between18-45 years. The sample was
randomly divided into two groups:
Group 1: included 20 molars ,a 4–5 mm wedge of mucosa adjacent
to the second molar was removed to obtain secondary healing.
Group 2: included 20 molars ,a rubber drain was inserted into the
extraction socket near the buccal fold after surgery and left for 72h.
Edema, pain and trismus were measured On first , third and seventh
day following surgery.
The findings showed a significant difference between the effect of
secondary closure and rubber drain on the Edema, pain and trismus
after surgical Extraction of Impacted Lower Third Molars.
The Edema, pain and trismus were less in secondary closure group.
The purpose of this study was to evaluate the success of Formocresol
pulpotomy compared with Ferric sulfate and Electro coagulation and Laser
pulpotomy in primary teeth. Fourty seven primary second molars of
children aged 5-8 years, were divided r
andomly into four groups: 10
Formocresol , 13 Ferric sulfate , 13 Electro coagulation, 10 Laser.
All teeth were filled with ZOE and sealed with Compomer, and S.S.Crown
as final restoration.
The success rate was 90 % - 84.6 % - 84.6 % - 83.3 % respectively.
These differences were not statistically significant p=0.05), but there were a
relation between the pretreatment physiologic resorption of roots and the
type of hemorrhage during the amputation procedure.
This study revealed that Ferric sulfate, and Electro coagulation, and Laser
pulpotomy are good alternative to Formocresol pulpotomy.
