Introduction
One of the significant public health issue is Headache1,2. It is the most frequent medical condition and the important reason for the utilization of medicines among general population3. Headaches are very much prevalent and have negative kind of effects on health4. These are basically of two categories, one is Primary and the other is Secondary. Those headaches are considered Primary which are of muscular (tension type) and vascular origin (migraine and cluster headache). Secondary headaches are those which occurs due to any other source like head and neck lesion or swelling5. One of the common Secondary headache is “Cervicogenic headache” which involves unilateral headache that refers from cervical spine or its components6. Of all kinds of headaches affecting global population, Cervicogenic headache accounts for 15-20% headaches with women affecting four times greater as compare to men7. According to recent studies, the pain in face and head in cervicogenic headache is usually due to cranial nerves(C1-C3) and also due to pathophysiological changes that occurs in cervical zygapophyseal joints (upper)8. Cervical pain and discomfort, as compare to distal regions like elbow and hand, also has a very high prevalence among dentists9.
Dental practitioners usually use to work in constricted zones for extended period of time in very uncomfortable positions which requires intemperate use of hands, back, neck and vision2. Dentistry is basically a very demanding profession which requires both, the concentration and precision. This profession is established on social interaction that is present between patients and care providers10. It is a distinctive job with concern to occupational hazards as well as the work demands.
A lot of importance has been given to ergonomics in dental profession in last few years and this is because of the increasing number of work related health problems in Dentist11. Health problems and dangers in dentistry can be categorized as psychological, physical, chemical, biomechanical and ergonomic12. According to the study conducted in Saudi Arabia, frequency of neck pain among Dentists is 66%13. Another study was done in 2006, which conclude that the persons with cervicogenic headache were having very low range of cervical extension/flexion14.
Malavde, Rutuja; Salunkhe, Pragati conducted research in 2020 on 81 middle aged dentists. The aim of the study was to check the presence of head ache among dental practitioners. They used observational study in which female gender was dominant. The outcome measures used were flexion rotation test and neck disability index. The conclusion of the study was 26.73% dental population suffered from cervicogenic headache16.
Another study conducted in 2018 on the prevalence of musculoskeletal problems among dentists. The aims of the study were to find the occurrence of musculoskeletal problems specifically neck, back and shoulder pain. The sample size of this research was 105 and an electronic questionnaire was used. This cross sectional study was conducted in Jeddah, Saudi Arabia. The results of this study showed that there was increased prevalence of musculoskeletal disorders in dentists18.
Another study conducted on 182 dental students in 2018. Dental students of first, third and final professional year were included in this study. This study aims to find out the occurrence of musculoskeletal disorders in dental students. A questionnaire was used to find the presence of musculoskeletal problems among participants. The results showed that girls were more susceptible to musculoskeletal disorders as compared to men. This study also showed that the most common site of musculoskeletal disorders is back and neck and these disorders are equally prevalent throughout the dental studies20.
A research conducted in 2016 on dental students of Naresuan University in Thailand. The study aims to find the frequency and risk factors related to musculoskeletal disorders in final year students of dentistry. The sample size was 68 and modified Nordic Musculoskeletal Questionnaire was used as a tool. The study concluded an increased incidence of neck pain due to poor posture and they suggest incorporating mild exercises in order to reduce the occurrence of musculoskeletal disorders21.
Arthisri, A S; Jain, Ashish R; Philip, Jacob Mathew; Krishnan et al conducted a research in 2017 on dental practitioners. The major aim of this study was to find the work related musculoskeletal disorders among dentists. The sample size was 297 dental practitioners and stratified sampling technique was used. According to this study the major sites affected due to dental profession were shoulder and low back. This study suggests to use proper ergonomic furniture and to perform regular workouts in the form of relaxation and postural exercises22.
A recent research conducted on the prevention of musculoskeletal disorders through ergonomic interventions in 2020. The main purpose of this study was to check the effect of proper ergonomics on the incidence of musculoskeletal problems in dental population. The research introduces multiple ergonomic design chairs and then follows up their effects on the prevention of musculoskeletal problems. This study proved a positive role of the ergonomic design furniture on the prevalence of musculoskeletal disorders in dentists23.

Discussion
Headache is a most common condition worldwide15. The current study screened cervicogenic headache among dentists who have been working for at least two years to maximum ten years for more than 5 hours daily. For this purpose flexion-rotation test was used. Purpose of this screening was working posture of dentists, because it is often seen that a sustained posture for long duration adversely affects joints and muscles. This study concluded that cervicogenic headache was present among 30.4% dentists out of 125 and among those 36.8 %( n=46) were male and 63.2 %( n=79) were female.
A recent systematic review and meta-analysis is done by E. Anarte- Lazo et al in 2021. They conducted this research on the distinguishing features of migraine headache, cervicogenic headache and asymptomatic headache. The aim of this study was to differentiate between these three categories through symptoms and manual tests. For this purpose they use cervical flexion rotation test and manual muscle testing. This study proved that cervical flexion rotation test is a gold standard tool in order to diagnose cervicogenic headache24. So in the current study, cervical flexion rotation test was used which showed that cervicogenic headache was present among 30.4% dentists out of 125. It was seen that the reason behind this was due poor biomechanics24.
In 2014, Gokcen et al conducted a study on the importance of craniovertebral and cervico- medullary angles in cervicogenic headache on the patients with diagnosed cervicogenic headache and concluded that as their craniovertebral and cervico-medullary angles decreased their pain scores increased. Similarly, in current study those dentists who had poor biomechanics and bad posture, the craniovertebral and cervico-medullary angles decreased and in turn causes cervicogenic head ache22.
SamerNarouze MD in 2018, conducted a research on cervicogenic headache. The research revealed that cervicogenic headache is more evident in females as compared to men. The results of current study also show that cervicogenic headache is more prevalent in females as compared to men among dentists25. The reason behind this is that the bad posture is more common in females as compared to male.
Shimohata et al, in 2017, conducted a cross sectional study including 70 patients with cervical spine disorders who were scheduled to undergo fusion or laminoplasty. Preoperatively, headache was diagnosed among them and they concluded that cervicogenic headache was present in 15/70 and these patients also have high frequency of neck pain21. Similarly in the current study, cervicogenic headache was present in those dentists that have poor biomechanics.
Limitations of the study were small size due to limitation of time and non-cooperating participants regarding test position. Recommendation of the study is that the future study should be conducted on cervicogenic headache that should include complete assessment of Dentist’s posture and ergonomics etc. A comparative study should be conducted on Prevalence of cervicogenic headache among male and female.
Conclusion
This study concluded that cervicogenic headache was present among 30.4% dentists out of 125 and among those 36.8% (n=46) were male and 63.2% (n=79) were female.
