Introduction
The treatment aspects in periodontology has evolved with the use of growth factors, periodontal regeneration techniques, modification of various flap designs and use of dental implants with ridge augmentation procedures thus making the speciality per se reach new heights.1 Moreover, with the development of internet and an easy access available to all periodontology journals, periodontal treatment is freely accessible to general dental practitioners. However, knowledge of periodontal diagnosis and treatment is usually limited to undergraduate level and most of times private practice deals only with chief complaint of patient. 1 When it comes to periodontal disease, most of its symptoms are noticed at the later stages and its usually then that the general dentists refer the case to a periodontist. 2 Thus the need of the hour is the early recognition of periodontal disease by the general dentist and basic periodontal examination be mandatory to all the teeth as a part of the routine dental checkup and refer the case to the specialist. 3 But it is noticed that most of the young general dentists treat periodontal cases on their own and keep the periodontal patients in their practices for years and perform repetitive sessions of soft tissue treatment on their own as opposed to having a specialist provide the treatment thus resulting in a compromised periodontium.4 Such patients when referred to a specialist are not benefited from periodontal treatment.
With the emerging concept of speciality dental practice, the patient will appreciate the knowledge of general dentist to diagnose the periodontal disease condition at an initial stage and will be more pleased to be under the specialist care. 5 Moreover, the services rendered by the periodontist will be more effective with more confidence in the field of speciality thus providing more benefits and a better service to the patient. 5, 6
Thus this study was conducted with an aim to evaluate the knowledge and perception of general dentists towards periodontal treatment and identify the referral relationship between them.
Subjects and Methods
This survey study was conducted from July 2019 to August 2019 with the questionnaire distributed to all the practicing general dentists of Hubli-Dharwad. The survey included the sample of 50 general dental practitioners with the qualification of Bachelor of Dental Surgery only and an experience of atleast 1-year in private practice setup. A well-structured pretested questionnaire which comprised of 20 questions was distributed wherein the questions were designed to assess the knowledge and perception of general dentists towards periodontal treatment and identify the referral relationship between them. It was a close-ended questionnaire with responses recorded as Yes or No. However, among the participants who enrolled in this study, no questions were left unanswered. The reliability of the questionnaire was checked with the pretested questionnaire.
Results
The present survey gives information about the knowledge and perception of general dentists towards periodontal treatment and identify the referral relationship between them. Out of the 50 general dental practitioners who participated in this study, 90.4% (47) of general dentists did believe in the success of periodontal treatment and did recommend their patients to undergo various periodontal treatment procedures. However, 88.5% (46) of the dentists performed most of periodontal surgeries like curettage, depigmentation procedures, flap surgeries, frenectomy, gingivectomy, crown-lengthening and phase I therapy on their own and 78% (41) of dentists referred cases to specialist only for grafting, ridge augmentation and dental implant procedures. So the present survey indicates that the role of a periodontist in private dental clinics in Hubli-Dharwad city was chiefly limited to major periodontal and implant treatment procedures. It was observed that about 71.2% (37) of dentists considered gingival health for prosthetic considerations and 94.2% (49) of them did evaluate periodontal condition before referring the case for orthodontic treatment. It was also noted that 84.6% (44) of dentists followed up periodontal cases as a part of maintenance phase and 57.7% (30) of them did attend CDE program regarding periodontal disease progression, its consequences and treatment outcomes at various stages of disease in past 1 year.(Table 1)

Discussion
In the recent past, the concept of speciality dental practice has been routinely implemented with the developing triad made by the referral doctor, referral patient and the specialist; and the success of this triad depends upon the understanding and respect among the team members.7 Unlike other dental specialities like Orthodontia, Pedodontia or Prosthodontics, the symptoms of periodontal disease clinically manifest at the advanced stages of destruction and most of the times private practice deals only with chief complaint of patient.2 Thus the need of the hour is the early recognition of periodontal disease by the general dentist and basic periodontal examination be mandatory to all the teeth as a part of the routine dental checkup – irrespective of patient’s chief complaint and refer the case to the specialist.2, 3 But it is noticed that most of the young general dentists treat periodontal cases on their own and perform repetitive sessions of soft tissue treatment as opposed to having a specialist provide the treatment thus resulting in a compromised periodontium. Such patients when referred to a specialist are not benefited from periodontal treatment.4 Thus the present survey study did evaluate the perception of general dentists towards periodontal treatment and identify the referral relationship between them.
In the present study, it was noticed that 90.4% (47) of general dentists did believe in the success of periodontal treatment and did recommend their patients to undergo various periodontal treatment procedures out of which 88.5% (46) of the dentists performed most of the periodontal surgeries like curettage, depigmentation procedures, flap surgeries, frenectomy, gingivectomy, crown-lengthening and phase I therapy on their own. This could be attributed to the adequate periodontal education gained by the dental practitioners at their BDS courses.1 However dental students at an undergraduate level receive only a limited educational background and exposure to surgical skills especially in cases demonstrating advanced periodontal destruction and high periods of risk factors.8 According to Mali et al6 periodontal intervention in severe forms of disease would only give unpredictable results. Thus the need of the hour is to establish a referral trend by the general dentist to a specialist at the initial stages of periodontal disease as the services rendered by the periodontist will be more effective and beneficial to the patient.5, 6 According to Cherian DA et al (2019)3 with the emerging concept of speciality dental practice, the patient will appreciate the knowledge of general dentist to diagnose the periodontal disease condition at an initial stage and will be more pleased to be under the specialist care. However, 78% (41) of dentists referred cases to specialist only for grafting, ridge augmentation and dental implant procedures. This is in accordance with the factors associated with dentists’ adoption of major periodontal treatment and implant therapy into practice.9
In the present study, it was observed that majority of the general dentists practicing in Hubli-Dharwad did consider the periodontal status before providing interdisciplinary treatment, more than half of the dentists followed up periodontal cases as a part of maintenance phase and a few of the general dentists did attend the CDE program regarding periodontal disease progression, its consequences and treatment outcomes in the past 1 year – all of which revealed that the dental practitioners in Hubli-Dharwad city did have adequate knowledge and positive perception towards periodontal treatment. However, it was noticed that 46 out of the 50 general dentists performed most of the periodontal surgeries like curettage, depigmentation procedures, flap surgeries, frenectomy, gingivectomy, crown-lengthening and phase I therapy on their own while 78% of dentists referred cases only for periodontal procedures associated with grafting, ridge augmentation and implant treatment which suggests that although patient referral system to the specialist is being implemented by the general dentists in hubli-dharwad city, it is only for major periodontal surgeries or severe forms of periodontal diseases.
Cherian DA et al (2019)3 suggested that patients when referred to the specialist at the worsening periodontal condition may not be benefited from the services of the specialist; also the services of the periodontist could be underestimated by the patient and the general dentist. So the need of the hour is to establish the referral trend to the specialist at the initial stage of periodontal disease so as to render a better and an effective treatment to the patient.3
In the present study, only 30 out of the 50 general dental practitioners did attend the CDE program regarding periodontal disease and treatment outcomes at different stages of disease in the past 1 year. According to Lee JH (2009)4, dentists who did not refer patients to the periodontist were less interested in attending CDE programs in periodontics than dentists who made such referrals, which is in accordance to the results of the present study where majority of the dentists performed most of the surgical periodontal treatment and phase I therapy on their own. According to Ghiabi and Mattews (2010),7 factors affecting the patient referral protocol to the specialist depends upon the proximity to a periodontist, interpersonal relationship between the dentist and the specialist, patient’s experience and positive feedback about the treatment rendered by the periodontist and success of the periodontal treatment performed by the specialist in the past.4, 7, 10 So the present survey indicates that the role of a periodontist in private dental clinics in Hubli-Dharwad city was chiefly limited to major periodontal and implant treatment procedures.
Conclusion
The present survey study showed an overall positive perception of general dentists towards periodontal treatment. However, the role of a periodontist was chiefly limited to major periodontal and implant treatment procedures. Thus more CDE programs on periodontal disease progression, its consequences and treatment outcomes at various stages of disease should be conducted in Hubli-Dharwad city so as to change the referral pattern of rendering periodontal treatment by the general dentists.
