“…The deposition of tubular/osteodentin along the dentinal wall, referred to as lateral dentin formation, is usually accompanied by pulp regeneration, leading to a reduction of the root canal space as demonstrated by histological analysis [10]. The accurate and highly reproducible calculation of teeth volumes has been reported by a cone beam computed tomography study to estimate the age of adults [29], and to examine the effect of orthodontic treatment [30]. Results in patients 1 and 4 demonstrated that regenerated pulp-like tissue decreased in volume at 28 weeks compared to that at 16 weeks.…”

BackgroundExperiments have previously demonstrated the therapeutic potential of mobilized dental pulp stem cells (MDPSCs) for complete pulp regeneration. The aim of the present pilot clinical study is to assess the safety, potential efficacy, and feasibility of autologous transplantation of MDPSCs in pulpectomized teeth.MethodsFive patients with irreversible pulpitis were enrolled and monitored for up to 24 weeks following MDPSC transplantation. The MDPSCs were isolated from discarded teeth and expanded based on good manufacturing practice (GMP). The quality of the MDPSCs at passages 9 or 10 was ascertained by karyotype analyses. The MDPSCs were transplanted with granulocyte colony-stimulating factor (G-CSF) in atelocollagen into pulpectomized teeth.ResultsThe clinical and laboratory evaluations demonstrated no adverse events or toxicity. The electric pulp test (EPT) of the pulp at 4 weeks demonstrated a robust positive response. The signal intensity of magnetic resonance imaging (MRI) of the regenerated tissue in the root canal after 24 weeks was similar to that of normal dental pulp in the untreated control. Finally, cone beam computed tomography demonstrated functional dentin formation in three of the five patients.ConclusionsHuman MDPSCs are safe and efficacious for complete pulp regeneration in humans in this pilot clinical study.

“…With the increase of the use of 3-dimensional imaging methods in dentistry, a number of studies that used CBCT to make the measurements related to pulpal chamber anatomy have been published. In these studies, it was proposed that CBCT is a more useful tool to determine pulpal chamber parameters and it enables precise and correct measurement of age-related volume changes in dental tissues (9,14,16,23).…”

“…Pulp-dentin complex changes in time resulting in a reduction of pulpal chamber volume due to continuous secondary dentin accumulation with age (9). While secondary dentin accumulation is a physiological process that is associated with age, tertiary dentin is formed in reaction to environmental stimuli such as chemical stimulants, dental caries, mechanical, chemical and thermal irritation during cavity preparation, and attrition, at the inner surface of the pulpal chamber that is exposed to stimuli (2)(3)(4)(10)(11)(12).…”

Aim: The aim of this study was to demonstrate the anatomical structure of pulp chamber, measure the volume of the total pulp chambers in mm3 and evaluate the pulp chamber volume changes by age and gender statistically in mandibular and maxillary first molars by means of CBCT. Methodology: In our study, CBCT examinations of patients between the ages of 7-18 years, which were carried out due to different reasons were evaluated retrospectively. The CBCT images of healthy total of 160 lower and upper right permanent first molar teeth were selected randomly and the volumes of the total pulp chamber were measured in mm3 with the 3D Slicer software program. We analyzed the collected data with statistical analysis methods and we evaluated whether there was any difference between the patients grouped according to the age in respect of volume changes in the total pulp chamber and whether there was any difference between the mean volume values and gender of the patients within the same group. Results: Comparison of the volume measurements of the lower and upper first permanent molar teeth between the groups showed that the volume values of the total pulp chamber decreased depending on the age (p<0.05). Regarding gender, volume decrease related to age was statistically more significant among females. We determined in all age groups except age 7-9 group that the volume value of the total pulp chamber of the upper permanent first molar teeth was statistically higher than the volume value of the total pulp chamber of the lower permanent first molar teeth (p<0,05). Conclusion: We believe that CBCT is an easy and conservative method for the 3D-imaging of the pulp chamber, volume measurement and examination of the dimensional changes of the total pulp chamber depending on deposition of secondary dentin.

Öz Amaç: Dental radyografilerin yaş tayininde güvenle kullanılabileceği yapılan çalışmalarla ortaya konmuş olup üç boyutlu görüntüleme yöntemlerinin son yıllardaki gelişimi ile bu alanda pek çok yeni çalışma yapılmıştır. Yapılan çalışmalarda, çenelerin sağ ve sol kadranları arasında belirgin simetri olduğu öne sürülmektedir. Bu çalışmanın amacı; mandibular premolar dişlerdeki yapısal değişikliklerin konik ışınlı bilgisayarlı tomografi (KIBT) görüntülerinde farklı radyolojik yaş tayini yöntemleri ile değerlendirilerek sağ ve sol kadranlar arasında farklılık olup olmadığının araştırılmasıdır. Gereç ve Yöntem: Mandibular sağ ve sol 1. ve 2. premolar dişlerin mevcut olduğu yüksek diagnostik kaliteye sahip 50 adet KIBT görüntüsünde; mandibular premolar dişlerin tümünde yapısal değişiklikler görsel olarak (modifiye Gustafson metodu), lineer ölçümlerle (Kvaal yöntemi) ve hacim ölçümleriyle (pulpa/ diş hacim oranı yöntemi) değerlendirilmiştir. Elde edilen veriler istatistiksel olarak değerlendirilmiştir. Bulgular: Yapılan tüm değerlendirmelerde, premolar dişlerin her biri için oluşturulan regresyon modelleri istatistiksel olarak anlamlı (p<0,001) bulunmuştur. Modifiye Gustafson metodu kullanılarak gerçekleştirilen görsel değerlendirmelerde 45 (R=0,734) ve 44 (R=0,707) no'lu dişlerin, Kvaal yöntemi kullanılarak gerçekleştirilen lineer ölçümlerde 35 (R=0,385) ve 44 (R=0,375) no'lu dişlerin, pulpa/diş hacim oranı yöntemi kullanılarak gerçekleştirilen değerlendirmelerde ise 35 (R=0,461) ve 34 (R=0,420) no'lu dişlerin yaş ile daha yüksek korelasyon gösterdikleri sonucuna ulaşılmıştır. Sonuç: Yaş tayini konusunda daha önce yapılan ve sağ-sol kadranlar arasında farklılık olmadığını öne süren çalışmaların aksine, çalışmamızda sağ-sol kadranlar arasında farklılık olduğu tespit edilmiştir.
