520 | |a Aims: To evaluate the tissues formed by the pulp stem cell homing technique through the histopathological sections, after a three months follow-up period. Materials and Methods: The study was performed on twelve right second premolars of twelve local breed female dogs, that were randomly selected form different areas of Mosul City. The study was divided into four stages, stage I (Induce infection), stage II (Disinfection), stage III (Treatment), and stage IV (3 months follow-up). In the stage IV the tooth and the surrounding bone segment was sectioned and routinely processed to produce H&Estained tissue sections that were evaluated under the light microscope. The histological examiners were evaluated presence or absence of 1st normal pulp-like tissue, 2nd newly hard tissue (bone,cementum, dentin),3rd empty/necrosis,4th intra-canal inflammation, 5th periapical inflammation, 6th apical narrowing and wall thickening. Results: The results have shown that 85.71% of specimens had normal pulp-like tissue ,100% had newly hard tissue structure, 14.28% had an empty canal necrosis, 57.14%had intra-canal inflammation, 71.42% had periapical inflammation, and 85.71% had apical narrowing. Conclusion: The pulp stem cell homing procedure showed an effective way to treat an open apex tooth and this procedure was increased the root length and thickness and also filled the pulp space with pulp-like tissue. The procedure did not regenerate the tooth structure, but formed a tissue like dental structure (dentin, bone and cementum) and these tissues did not for regeneration, but for tissue repair. | ||

Materials and Methods: The study was performed on twelve right second premolars of twelve local breed female dogs, that were randomly selected form different areas of Mosul City. The study was divided into four stages, stage I (Induce infection), stage II (Disinfection), stage III (Treatment), and stage IV (3 months follow-up). In the stage IV the tooth and the surrounding bone segment was sectioned and routinely processed to produce H&Estained tissue sections that were evaluated under the light microscope. The histological examiners were evaluated presence or absence of 1st normal pulp-like tissue, 2nd newly hard tissue (bone,cementum, dentin),3rd empty/necrosis,4th intra-canal inflammation, 5th periapical inflammation, 6th apical narrowing and wall thickening. Results: The results have shown that 85.71% of specimens had normal pulp-like tissue ,100% had newly hard tissue structure, 14.28% had an empty canal necrosis, 57.14%had intra-canal inflammation, 71.42% had periapical inflammation, and 85.71% had apical narrowing. Conclusion: The pulp stem cell homing procedure showed an effective way to treat an open apex tooth and this procedure was increased the root length and thickness and also filled the pulp space with pulp-like tissue. The procedure did not regenerate the tooth structure, but formed a tissue like dental structure (dentin, bone and cementum) and these tissues did not for regeneration, but for tissue repair. stem cell homing immature apex tooth open apex tooth dogs Dentistry Ghada Younis Abdulrahman verfasserin aut In Al-Rafidain Dental Journal University of Mosul, College of Dentistry, 2020 21(2021), 1, Seite 96-109 (DE-627)756824257 (DE-600)2727311-8 19980345 nnns volume:21 year:2021 number:1 pages:96-109 https://doi.org/10.33899/rden.2020.128219.1051 kostenfrei https://doaj.org/article/c2fe0c018c7b44c29caba7fad67f2aa9 kostenfrei https://rden.mosuljournals.com/pdf_167815_238d13d65de620410497967e864899f0.html kostenfrei https://doaj.org/toc/1812-1217 Journal toc kostenfrei https://doaj.org/toc/1998-0345 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_73 GBV_ILN_74 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_602 GBV_ILN_2014 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 21 2021 1 96-109 |

Histomorphological Evaluation of Teeth After Three Months Follow up of Pulp-Cell Homing Procedure in Teeth with Incomplete Apex Formation in Dogs |
abstract |
Aims: To evaluate the tissues formed by the pulp stem cell homing technique through the histopathological sections, after a three months follow-up period. Materials and Methods: The study was performed on twelve right second premolars of twelve local breed female dogs, that were randomly selected form different areas of Mosul City. The study was divided into four stages, stage I (Induce infection), stage II (Disinfection), stage III (Treatment), and stage IV (3 months follow-up). In the stage IV the tooth and the surrounding bone segment was sectioned and routinely processed to produce H&Estained tissue sections that were evaluated under the light microscope. The histological examiners were evaluated presence or absence of 1st normal pulp-like tissue, 2nd newly hard tissue (bone,cementum, dentin),3rd empty/necrosis,4th intra-canal inflammation, 5th periapical inflammation, 6th apical narrowing and wall thickening. Results: The results have shown that 85.71% of specimens had normal pulp-like tissue ,100% had newly hard tissue structure, 14.28% had an empty canal necrosis, 57.14%had intra-canal inflammation, 71.42% had periapical inflammation, and 85.71% had apical narrowing. Conclusion: The pulp stem cell homing procedure showed an effective way to treat an open apex tooth and this procedure was increased the root length and thickness and also filled the pulp space with pulp-like tissue. The procedure did not regenerate the tooth structure, but formed a tissue like dental structure (dentin, bone and cementum) and these tissues did not for regeneration, but for tissue repair. |

Materials and Methods: The study was performed on twelve right second premolars of twelve local breed female dogs, that were randomly selected form different areas of Mosul City. The study was divided into four stages, stage I (Induce infection), stage II (Disinfection), stage III (Treatment), and stage IV (3 months follow-up). In the stage IV the tooth and the surrounding bone segment was sectioned and routinely processed to produce H&Estained tissue sections that were evaluated under the light microscope. The histological examiners were evaluated presence or absence of 1st normal pulp-like tissue, 2nd newly hard tissue (bone,cementum, dentin),3rd empty/necrosis,4th intra-canal inflammation, 5th periapical inflammation, 6th apical narrowing and wall thickening. Results: The results have shown that 85.71% of specimens had normal pulp-like tissue ,100% had newly hard tissue structure, 14.28% had an empty canal necrosis, 57.14%had intra-canal inflammation, 71.42% had periapical inflammation, and 85.71% had apical narrowing. Conclusion: The pulp stem cell homing procedure showed an effective way to treat an open apex tooth and this procedure was increased the root length and thickness and also filled the pulp space with pulp-like tissue. The procedure did not regenerate the tooth structure, but formed a tissue like dental structure (dentin, bone and cementum) and these tissues did not for regeneration, but for tissue repair.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">stem cell homing</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">immature apex
