AIM: (The aim of this study was to determine the prevalence and severity of neck pain in dentists of north India) [h1]. MATERIALS AND METHODS: Following ethical approval, a cross sectional study was conducted on 74 randomly selected dentists. Questionnaires were used to collect personal and occupational characteristics as well as the prevalence and risk factors of neck pain. Subjects were assessed by visual analogue scale and neck disability questionnaires for pain intensity and functional

CONCLUSION: Results indicated that the prevalence of neck pain and neck disability in dentists appears to be high. KEYWORDS: Prevalence, visual analogue scale, neck disability index. INTRODUCTION: Dentist work demands high precision and is often performed with the cervical spine flexed forward and rotated 1 . This induces high static load in the neck region. Prolonged Static load of long duration and repeated movements can result in neck pain, tension neck syndrome, muscle imbalance or cervical instability. Tension neck syndrome: Tension neck syndrome results in pain, stiffness and tenderness in the neck and trapezius muscles, often with muscle spasms or tender trigger points. These symptoms may not always be localized in the neck; pain can occur between the shoulder blades, radiate down the arms or up into the base of the skull. Headaches also are a common symptom of TNS. Forward head posture is a primary contributing factor to TNS, a problem frequently seen among dentist due to years of poor posture involving holding the neck and head in an unbalanced forward position to gain better visibility during treatment. Neck pain has been shown to be associated with forward head posture is 20 degree or more for 70 percent of working time. On average, dentist work with forward head posture of at least 30 degree for 85 percent of their time in the operatory 2 . Poor endurance of the neck stabilizing muscles can worsen this pain in occupations where forward head postures are required. Neutral head posture is ear over shoulder when viewed from the side. Forward head posture occurs when the natural curve at the back of the neck is put out of balance by the sustained weight of the head in the forward position. This can trigger (the strain)[h1] on the neck and upper back structures. Muscles imbalances: Occupations such as dentistry, where forward head and rounded shoulder postures are common, predispose workers to a unique muscle imbalance that is a primary contributor to TNS, (thoracic)[h1] outlet syndrome and numerous other myofascial pain syndromes. These imbalances develop between the neck and shoulder muscles that stabilize, and those that move. The delivery of dental care requires excellent endurance of the primary shoulder girdle Otorhinol aryngology and Head Neck Surgery,
