| Abstract|| |
There are many etiological factors for nonplaque-induced gingival diseases, out of which physical trauma due to psychiatric reasons leading to self-infliction is less studied upon. This case report presents one such case which has been successfully treated stepwise where psychological counseling was done to restrain from habit followed by using an innovative laterally positioned periosteal pedicle graft for dehiscence coverage.

| Introduction|| |
A habit may be defined as a frequent or constant practice or an acquired tendency which has become fixed due to frequent repetition. These habits are broadly classified as obsessive and nonobsessive disorders, which may be intentional, unintentional, or either functional habits or self-inflicting masochistic habits. Many theories have been put forward for the development of oral habits which includes either due to a learned pattern due to neuromuscular immaturities leading to an unconscious repetitive pattern or due to deep-seated emotional/psychological or psychosexual behavior wherein gratification is derived by self-abuse (pain upon oneself).,
Gingivitis artefacta is a type of periodontal disease caused by self-inflicting injuries to gingival tissues either due to scratching or “picking” of gingiva with finger nails or any foreign object leading to denudation of soft tissue and bone in extreme cases of mutilation. The important factor lies in the fact that although typical features of oral self-inflicting behaviors (SIB) are well documented in literature, they often present a difficult diagnostic problem for dentist and psychiatrist since even when diagnosed their treatment and management modalities are not clearly understood. The purpose of the present article is to report a case of gingivitis artefacta due to anxiety and stress leading to self-inflicted gingival injury leading to complete dehiscence of lower incisor due to nail picking in an adult male. This case also highlights the importance of psychotherapy and repeated counseling to restrain and break the habit and management of dehiscence with an innovative lateral periosteal pedicle graft (PPG) wherein the regenerative potential of periosteum was utilized for soft tissue coverage and to increase the width and thickness of attached gingiva to a maintainable level.
| Case Report|| |
A 35-year-old male was referred from Department of Psychiatry who was diagnosed with anxiety and depression to the Department of Dental surgery, Armed Forces Medical College, Pune, for opinion and management of dehiscence due to masochistic habit. On electing the history of presenting illness, this patient was a known case of depression and anxiety due to socioeconomic and job insecurity. He was a migrant from Assam (North eastern part of India) in search of better prospect of life and was working as a daily wage construction employee and as a security guard in night. He reported to Department of Psychiatry 6 months back with the chief complaint of sleeplessness, insomnia, lethargy, and severe depression due to hopelessness from life. He had developed this factitious habit of gingival picking in the lower anterior tooth with fingernail during night duty hours due to loneliness and attained pleasure from pain upon self. These unconscious repeated habits aggravated over a period of time and lead to complete denudation of soft and hard tissues till apex of tooth #31 measuring approximately 10 mm × 4 mm in length/width [Figure 1]. He was undertreatment with antidepressants (Alprax 0.5 mg-alprazolam) and frequent psychological counseling and positive reinforcement toward life for last 6 months and was advised for change of job with better financial benefits with decreased stress. He was responding well to drugs and psychological counseling and was coping well with anxiety and stress. He was referred to Department of Dental surgery by the treating physician for the management of dehiscence.
On general physical examination, he was moderately built and nourished, well oriented to time, place, and person. Intraoral soft tissue examinations were all normal except the presence of gingival recession/dehiscence in relation to tooth #31. The length/width of recession was 11/4 mm with visible apical root tip. The tooth was nonvital with no mobility. The adjacent interdental soft and hard tissues were normal. A diagnosis of Millers Class II was made since the recession was extending beyond the mucogingival junction, but there was no pathologic migration with soft and hard tissue loss in the interdental area as seen in intraoral periapical radiograph. After obtaining an informed consent and routine blood and urine investigations, a treatment plan was made and decided to treat this case in two phases:
- Phase I: Patient was put in maintenance phase where the patient was initially subjected to scaling and was prescribed 0.12% chlorhexidine mouth rinse twice daily till completion of the treatment followed by repeated counseling, patient education, motivation, and restraining from SIB in which the patient was made to realize the damage caused by the habit
- Phase II: Surgical phase – The patient was taken up for single sitting root canal treatment and apicoectomy followed by esthetic root coverage along with increasing the width and thickness of attached gingiva using the PPG in a single surgery.
The facial skin around the oral cavity was scrubbed with 7.5% povidone iodine solution, and the intraoral surgical site was painted with 5% povidone iodine solution. The patient was locally anesthetized with 2% lignocaine with 1:80,000 adrenaline. After obtaining local anesthesia, an intrasulcular incision was made with No. 11 Bard Parker surgical blade; depapillation along the length of defect was done till the apex followed by single sitting endodontic treatment and obturation with Gutta-percha points and intracanal medicament [Figure 2]. Apicoectomy of the apical end was done to create a closed, hermetic-sealed compartment.
Root surface was planned with curettes, and root surface was modified with tetracycline. Two horizontal incisions slightly apical to cement enamel junction were made preserving the gingival margin of the neighboring teeth. This incision was perpendicular to tooth #31, and approximately twice the width of the recession followed by two vertical incisions extended beyond the mucogingival junction keeping the base of the flap wider. A partial thickness flap was raised carefully along the mesial and distal sides of tooth #31 [Figure 3]. The periosteum along the distal side was separated from the bone carefully with a periosteal elevator keeping the pedicle of 2 mm intact along the length of the root like a “wrap around” till the apex [Figure 4]. This PPG was secured and sutured to adjacent periosteum with resorbable sutures [Figure 5]. The partial thickness flap on the distal side was secured to its original position with 3-0 silk sutures whereas the partial thickness flap on mesial side was laterally slided so as to cover the “wrap around” periosteum over the defect completely. The distal end of the flap was sutured to periosteum which was exposed due to lateral sliding [Figure 6]. Periodontal pack and postoperative instructions were given to the patients. Patients were prescribed antibiotics and analgesics and instructed for oral rinsing with 0.2% chlorhexidine mouth wash twice daily. Both the sutures and pack were removed one week postoperatively followed by regular recall visit every 15 days for 2 months. At the end of nine months, there was uneventful healing with no pain, swelling, and infection. Postoperative length/width of recession was 3/4 mm with approximate soft tissue coverage of almost 70% [Figure 7]. The diagrammatic representation of the surgical procedure is given in [Figure 8].
| Discussion|| |
Dehiscences are isolated areas in which the root is denuded of soft tissue, bone, and periosteum which extends through the marginal bone. Such defects occur more often on the facial surface of anterior teeth than posteriors generally due to prominent root contour, malposition, and thin bony plate.
Although complete regeneration of soft and hard tissue over defects such as dehiscence is still an elusive goal, the quest for methods for predictable regeneration has led to new methods and techniques. One of such tissue engineering techniques with promising outcomes in the recent times is the use of periosteum. This case report is one of its kinds wherein the periosteum is utilized for esthetic soft tissue coverage over the dehiscence lost due to SIB. This graft utilizes the osteogenic potential of pericytes in the periosteum and its ability to differentiate into osteoprogenitor cells under appropriate condition or stimuli making it an ideal reservoir for regeneration due to its highly dense neuromicrovascular network, presence of fibroblasts, osteoblasts, and adult mesenchymal progenitor stem cells.
According to AAP classification (1999 World Workshop in Periodontics), the gingival diseases are broadly classified as plaque-induced and nonplaque-induced gingival lesions. Gingival diseases due to trauma either thermal, physical, or chemical injuries are grouped under a broad category of nonplaque-induced gingival lesions. Factitious physical injuries/masochistic habits or SIB to gingiva are group of complex psychological disorders which results in physical damage and perhaps pain upon oneself.
Most accepted classification for oral SIB was suggested by Stewart and Kernohan in 1972 wherein Type A injuries are superimposed on a preexisting condition, such as herpetic lesions or localized gingival infection. Type B injuries are secondary to established habits, such as finger sucking or nail biting. Type C injuries have unknown or complex etiologies, which would include injuries due to psychological problems. Such deliberate self-injury to gingiva is termed as gingivitis artefacta. Depending on extend and severity of the compulsive behavior, it can occur as major and minor form.
Gingivitis artefacta, though not uncommon, but most published case reports mentions of different methods of self-infliction. Diagnosis and management of SIB are still a dilemma since there is no laid down management protocols. The aim of this article was to make aware of occurrence of such stress- and anxiety-related SIB in oral cavity to practicing medical and dental professionals. A timely diagnosis and team effort of periodontist and psychiatrist are needed for successful treatment of such cases with psychotherapeutic counseling with management of underlying stress followed by esthetic periodontal rehabilitation.
Although there are different treatment modalities advocated for recession coverage like free gingival autograft by Bjorn 1963; Sullivan and Atkin in 1968, Lateral sliding flap by Grupe and Warren, Coronally advanced flap by Bernimoullin in 1975 and the gold standard of recession coverage Subepithelial connective tissue graft by Raetzke, 1985; Langer and Langer, 1985. Very less attempts have been made for soft tissue coverage on dehiscence since the choice of technique depends on the defect size (length and width), localization of esthetic zone, and need for augmentation of attach gingiva. Use of periosteum with rich vascular plexus for soft tissue coverage over avascular cementum was advocated by Mahajan with predictable and viable graft., Similarly, in our case, a modification of Mahajan's technique was utilized to achieve maintainable soft tissue coverage with increased width and thickness of attached gingiva over the dehiscence.
Periodontitis-involved root surface altering can be done with root surface biomodification for formation of new connective tissues attachment. Removal of bacteria deposits, calculus, and endotoxins from cementum is generally considered essential for new attachment. The technique described even though looks feasible requires certain prerequisites such as good surgical dexterity, case selection, and periosteum firmly adherent to underlying bone. Postoperative healing in this case was uneventful with no recurrence of SIB. However, the question still remains is whether there is true regeneration of new cementum and bone beneath the soft tissue by the periosteum. Thus, histological studies are required to reveal the exact type of healing and attachment to the cementum and randomized controlled trials to compare it with already established soft tissue coverage techniques for regular use.
Self-inflicted masochistic habits in oral region are generally targeted toward gingiva and are stress and psychologically mediated. These gingival injuries can sometimes test the clinician's diagnostic abilities. Psychiatrist or a counselor is important in the identification of triggering factors and to manage it by regular counseling to cope with stress. Behavior modification, positive reinforcement, and habit withdrawal with restrain are keys to manage such SIB. The outcome of this surgical technique suggests that laterally positioned PPG can achieve the goal of soft tissue coverage over dehiscence.
