In this study 60 adult patients will participate and divided into two groups (30 for each). The first group will be anesthetized using 2 % lidocaine with 1:80,000 adrenaline by inferior alveolar nerve block technique, while the second group will be anesthetized using 4 % articaine with 1:100,000 adrenaline via buccal and lingual infiltration technique in posterior teeth area. Then patients will wait for five minutes after receiving a local anesthetic injection before extraction could begin.

After that every tooth's buccal, lingual, mesial, and distal surfaces will be examined using a disposable dental explorer. Then by visual analog scale (VAS) which provides accessible, sensitive, valid, and reliable means to measure a variety of subjective parameters the pain score will be registered during tooth extraction.

Female patients who are breastfeeding or pregnant, those allergic to local anesthetics, lacking full mental ability, currently taking opioids, having an infection at the extraction site, or those under the influence of medicines that alter their perception of pain will be excluded from the study.

Inclusion Criteria:

• clinically healthy patients

Exclusion Criteria:

• Breastfeeding or pregnant
• Allergic to local anaesthetics drugs
• Lack full mental ability
• Infection at the extraction site
• Patient who currently taking opioids or under the influence of medicines that alter their perception of pain are not candidates for tooth extraction
