As a part of smile’s harmony, interdental papilla plays an important role in orofacial esthetics. Loss of 

interdental papilla of gingiva can lead to black spaces in odontology, which affects the smile esthetics

and leads to phonetics and functional damage.1 This black triangle can even cause food impaction. The 

etiology of this loss is mainly because of gingival inflammation, attachment loss, resorption of 

interproximal bone height and periodontal surgical therapy. Growth factors, platelet derivatives and 

low level laser therapy has been used previously for papillary regeneration, but papillary reconstruction 

is most challenging problem because of the minor blood supply.

2 Surgical reconstruction of interdental papilla also presents as challenge in obtaining good results.3 Photo biomodulation therapy (PMBT) 

modulates biologic activity and has shown to reduce inflammation and pain, prevent necrosis and has 

shown to stimulate healing of wound and regeneration of tissues. PMBT has also been proven to

enhance the production of adenosine triphosphate, vasodilatation and tissue regeneration.4 Hemolaser 

therapy is a modified PBMT which regenerates papilla and fills the black triangles. The aim of this 

study is to evaluate the effectiveness and efficiency of hemolaser therapy on papillary regeneration.
