gingival recession has a diverse etiology and may result in exposure and secondary damage of exposed root surfaces . the consequences may include gingivitis , periodontitis , and hypersensitivity . with a prevalence ranging from 37.8% ( in the 3039 age group ) to 90.4% ( the 8090 age group ) , it is a problem affecting all ages to varying degrees . whereas the management can include surgical treatment options , sometimes a more conservative , yet still esthetic approach may be required . the use of gingival - colored composites provides one such alternative and can be applied to varying presentations of the problem . this paper seeks to outline the background to the problem and present some clinical scenarios where gingival - colored composite has been used to good effect in the management of lesions arising from gingival recession . gingival recession can be defined as the apical migration of gingival margin to the cementoenamel junction . causes include periodontal disease , accumulations , inflammation , improper brushing and flossing habits , unstable occlusal relationships , and dominant roots.1 the occurrence may or may not be in conjunction with loss of attached tissue and may be associated with sensitivity because of the exposed dentin . the data from the us national survey show that 88% of seniors ( age 65 ) and 50% of adults ( age 1864 ) present with recession in one or more sites . as there is an increase in age , there is a progressive increase in frequency and extent of recession being observed.2 the prevalence of recession was 37.8% in the youngest age cohort ( 3039 years ) , and in contrast , the oldest cohort , aged 8090 years , had a prevalence of 90.4% ( more than twice as high).3 
 table 1 outlines the varied factors that can be associated with gingival recession . therefore , it can be seen that gingival recession is a common occurrence with a multifactorial etiology and is always associated with alveolar bone dehiscences.13 the amount of bone around the roots plays a role , and even around implants , it has been shown that the thicker the buccal bone , the thicker the crestal labial soft tissue thickness and vice versa.14 the consequences can include esthetic concerns,15 gingival bleeding and plaque retention , hypersensitivity,16 and caries.17 
 table 2 outlines the factors that should be considered in managing gingival recession defects . interdisciplinary approaches are often required for restoration of esthetics and function of the periodontal supporting structures lost due to periodontal disease.23 prosthetic approaches to reproduction of artificial gingival tissue include porcelain , acrylics ( denture base material ) , silicone - based soft materials , or co - polyamide and composite resin,23 each with its associated merits , demerits , and specific indications . for example , a removable prosthesis can facilitate a larger volume of tissue replacement without disturbing other dental units while allowing proper cleaning , whereas for fixed restoration of soft tissue in the esthetic zone , gingiva - colored ( pink ) porcelain can help in re - creating natural tooth proportions and provide a realistic alternative to surgery.23 while surgical treatment can be successful in re - creating favorable esthetic anatomy as well as achieving accurate tissue contour in cases when minor amounts of tissue are reconstructed , long - term results vary because of the vascularity and complexity of the interdental space.24 factors such as surgical costs , healing time , discomfort , and varying long - term results make this choice unpopular.24 in order to protect the marginal periodontal tissues , prevent further tooth structure loss , reduce hypersensitivity , and improve esthetics , it is advocated that lesions with a depth of 0.5 mm be treated restoratively.25 choice of restorative materials for these lesions includes both glass ionomer cements ( gics ) and composite resins.26,27 however , gics prove to have a more versatile clinical applications in the case of non - carious cervical lesions.28 gics have a similar thermal expansion coefficient to that of tooth structure.26 the material also exhibits the ability to bond successfully with enamel and dentine as well as long - term fluoride release and favorable biocompatible properties.29 gics in combination with surgical periodontal procedures such as coronally positioned flaps30 and connective tissue grafts31 have shown great promise as a management strategy for non - carious cervical lesions . similar results have been obtained with microfilled resin composites and coronally positioned flaps.32 if tooth - colored restorative materials are utilized to restore cervical tooth exposure as a result of severe recession , the disproportionate appearance of the visible crown may give a dissatisfying result . gingival - colored composites in conjunction with the utilization of tooth - colored restorative material allow for a minimally invasive adhesive restorative technique.33 the use of pink composite resin as an artificial gingival tissue was first described by zalkind and hochman in the management of a cervical defect.34 the patients in the following cases were seen by the first author in practice and written consent was given by the patients for pictures and demographics to be used for research , publication and teaching as long as anonymity was maintained . ethical approval was not sought as treatment provided was part of routine care offered in a private practice setting . the following cases outline the use of gingiva - colored composite in varying clinical scenarios . the composite used in the restoration of these cases was amaris gingiva ( voco america , inc . , indian land , sc , usa ) , a branch of the german company voco gmbh , germany . glycidyl dimethacrylate ( bis gma ) , urethane dimethacrylate ( udma ) , and tetraethyleneglycol dimethacrylate ( tegdma ) as matrix monomers . the mixing of these in various amounts , and the combination of a base shade called nature , allows customization of the gingiva shade for any patient . the three shades of opaquer in amaris gingiva enable the operator to blend the shades to produce a color that closely matches the patient s gingiva . alternatively , the opaquer can be applied directly to the exposed root surface in a pattern mimicking the pigmentation seen on the patient s gingiva , thus enhancing the esthetic result . the versatility of the material enables it to be used in defects of varying sizes and depths as illustrated in the cases presented . case 2 shows the restoration of a defect of similar recession but not as deep into the tooth structure . in both cases , cases 3 and 4 illustrate the ability of the material to be used in recession defects of varying severity . whereas the defects in case 3 are not > 2 mm , case 4 shows restoration of three defects between 4 and 5 mm . the cases also demonstrate the gingiva - colored composite being used in conjunction with tooth - colored composite as in cases 2 and 3 and also with dentures in order to maximize esthetics . a 35-year - old female patient presented with mild sensitivity in the left maxillary region . after being presented with options for management , the patient elected to have gingiva - colored restorations placed . figure 2 shows the lesions after restoration . a 60-year - old female patient presented for routine dental cleaning . during treatment , the patient opted to have the defects restored using gingival - colored composites . for tooth # 45 ( lower right second premolar ) , gingival - colored composite material and tooth - colored composite were used to restore a defect of depth > 0.5 mm . however , tooth # 44 , with a defect < 0.5 mm , was restored using gingival - colored restorative material only ( figure 4 ) . a 65-year - old female patient presented for removal of a defective gold splice closing a mesial diastema as seen in figure 5 . as part of the treatment to provide better esthetics and improve the mesial distal contour and emergence profile of the central incisors , gingival - colored restorative material was used to restore the cervical lesions , and tooth - colored composites were used to restore the diastema and reshape the coronal aspect of the teeth ( figure 6 ) . a 55-year - old man presented for replacement of missing units in the maxilla and mandible . clasp was used to improve esthetics around the upper left canine ( figure 7 ) . the patient then decided to have the cervical lesions on the upper left canine and premolars restored with gingival - colored composite to try and achieve maximum esthetics ( figure 8) . the case demonstrates the versatility of the gingiva - colored composite being used with dentures and esthetic clasps . a 35-year - old female patient presented with mild sensitivity in the left maxillary region . after being presented with options for management , the patient elected to have gingiva - colored restorations placed . a 60-year - old female patient presented for routine dental cleaning . during treatment , recession defects were seen on the lower right premolars ( figure 3 ) . the patient opted to have the defects restored using gingival - colored composites . for tooth # 45 ( lower right second premolar ) , gingival - colored composite material and tooth - colored composite were used to restore a defect of depth > 0.5 mm . however , tooth # 44 , with a defect < 0.5 mm , was restored using gingival - colored restorative material only ( figure 4 ) . a 65-year - old female patient presented for removal of a defective gold splice closing a mesial diastema as seen in figure 5 . as part of the treatment to provide better esthetics and improve the mesial distal contour and emergence profile of the central incisors , gingival - colored restorative material was used to restore the cervical lesions , and tooth - colored composites were used to restore the diastema and reshape the coronal aspect of the teeth ( figure 6 ) . a 55-year - old man presented for replacement of missing units in the maxilla and mandible . a clear clasp was used to improve esthetics around the upper left canine ( figure 7 ) . the patient then decided to have the cervical lesions on the upper left canine and premolars restored with gingival - colored composite to try and achieve maximum esthetics ( figure 8) . the case demonstrates the versatility of the gingiva - colored composite being used with dentures and esthetic clasps . comprehensive knowledge of facial esthetics , tooth morphology , available restoration techniques , and communication skills , combined with an understanding of smile components , teeth , gingival tissues , and lips , is integral in esthetic dentistry.23 ensuring that the correct width  length ratio is established for maxillary anterior teeth35,36 helps to determine ideal gingival levels which generally run parallel to the upper lip and are bilaterally symmetrical . other characteristics of the tissue relationships have been well documented.37,38 resin - based composites and glass ionomer cements have been proven to produce positive results in treating class v lesions and associated gingival recession.2628,39 should further recession take place , additions of composite could be made to cover the resulting defect , although in such a case , serious consideration would need to be given to why the recession was progressing . careful finishing of the margin of the gingival composite would be necessary to ensure that plaque trapping around the restoration did not contribute to this situation . it is confirmed clinically that composites have no adverse effects on gingival health , as well as that there is reduced inflammatory response to properly contoured and finished / polished composite resins in comparison to carious lesions that remain untreated.39 to date , no studies have been done comparing the shelf life of gingival - colored restorative material with regular composites or gic , and this would be an area for further investigation . the application of tooth - colored composite and gic restorative materials to teeth presenting with gingival recession often results in the restored tooth or teeth appearing overly long and subsequently unesthetic.33,40 in light of this clinical observation , manufacturers have sought to create restorative materials to better exhibit the esthetic qualities of the gingiva in order to address this need . in restoring defects caused by gingival recession , a gingival - colored composite would provide an option for bonding a simple restoration to the exposed root as with any other class v restoration as is seen in cases 14 . in addition to the esthetic value of the gingival - colored restorative materials , their use also enables the application of minimally invasive procedures as an option to restore the effects of gingival recession as in case 1.40 in combination with tooth - colored restorations as seen in cases 2 and 3 , this could produce the desired esthetic result . a false or pseudo gingival sulcus can be created coincident with the previous free gingival margin , thereby improving soft tissue esthetics with adhesive materials.41 in cases where the patient may be wearing dentures , an attempt can be made to match the height of this sulcus to the height of the gingival margin on the denture improving the chance of an esthetic match as seen in cases 3 and 4 . the gingiva - colored composite restoration would allow the patient an opportunity to see the esthetic result of having the gingiva replaced in this region and the effect with the altered appearance of the front teeth as a whole . this treatment option provides a practical clinical solution for patients that is economically viable and esthetically pleasing,40 allowing the patients to visualize the final result and even possibly better inform their decision to undergo surgery . cervical lesions resulting from gingival recession often require periodontal surgical procedures to correct the effects of gingival recession and consequent esthetic defects . gingival - colored composite provides dental practitioners with a versatile material that can be used to directly restore cervical defects caused by gingival recession , thus correcting the appearance of the gingival anatomy . it offers a treatment option that may increase patient satisfaction through the provision of a cost - effective , minimally invasive solution with highly esthetic results .
