Bone formation initially exceeds bone resorption, but by the third decade, such formation is reversed, resulting in a net loss of bone mass. This resorption, in turn, increases bone fragility and susceptibility to fracture. This study aimed to evaluate the effects of low-level laser therapy (LLLT) on bone regeneration in the expanded premaxillary suture in an ovariectomized rat model.\n                    <jats:bold>\n                      <jats:italic toggle=\"yes\">Methods:<\/jats:italic>\n                    <\/jats:bold>\n                    Thirty-two 12-week-old female Wistar albino rats were used in the experiment. All of the animals underwent ovariectomy 3 months before the experiment. Expansion appliances were affixed to the maxillary incisors for the expansion of premaxillary sutures. The premaxillary sutures of the laser group were exposed to 5\u2009J\/cm\n                    <jats:sup>2<\/jats:sup>\n                    laser energy, and no treatment was performed for the controls.

The CG1 and CG2 groups showed a significantly higher number of osteoclasts than did the LG1 and LG2 groups, respectively (p=0.005), (p=0.032). The LG2 group exhibited a capillary increase similar to that of the other groups, without statistically significant differences.\n                    <jats:bold>\n                      <jats:italic toggle=\"yes\">Conclusions:<\/jats:italic>\n                    <\/jats:bold>\n                    On the basis of our methodology and results, we conclude that low-level laser associated with rapid maxillary expansion influences bone regeneration in sutures, thereby accelerating healing, even in ovariectomized rats. We found that LLLT decreased osteoclastic activity in the ovariectomized rats. Therefore, preventing osteoporosis necessitates further investigations to clarify the effect of LLLT on postmenopausal patients.\n                  <\/jats:p>","DOI":"10.1089\/pho.2014.3820","type":"journal-article","created":{"date-parts":[[2015,2,26]],"date-time":"2015-02-26T11:06:50Z","timestamp":1424948810000},"page":"136-144","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":16,"title":["Effects of Low-Level Laser Therapy on Changes in Inflammation and in the Activity of Osteoblasts in the Expanded Premaxillary Suture in an Ovariectomized Rat Model"],"prefix":"10.1177","volume":"33","author":[{"given":"Mutan Hamdi","family":"Aras","sequence":"first","affiliation":[{"name":"Gaziantep University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zehra","family":"Bozdag","sequence":"additional","affiliation":[{"name":"Gaziantep University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tuncer","family":"Demir","sequence":"additional","affiliation":[{"name":"Gaziantep University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R\u0131dvan","family":"Oksayan","sequence":"additional","affiliation":[{"name":"Osmangazi University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saim","family":"Yan\u0131k","sequence":"additional","affiliation":[{"name":"Gaziantep University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oral","family":"S\u00f6k\u00fcc\u00fc","sequence":"additional","affiliation":[{"name":"Gaziantep University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,3]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/23.4.363"},{"key":"e_1_3_3_3_2","doi-asserted-by":"crossref","first-page":"1221","DOI":"10.1097\/SCS.0b013e3182997816","article-title":"The effects of zoledronic acid on mandibular fracture healing in an osteoporotic model: a stereological study","volume":"24","author":"Sener I","year":"2013","unstructured":"Sener I, , Bereket C, , Kosker H, , Turer A, , Tek M, , Kaplan S.
