Background and Aim: Achieving adequate pulpal anesthesia could be challenging in mandibular molars. There are some disagreements about the success rate of local infiltration anesthesia with articaine as primary injection. Therefore, the aim of this study was to assess the efficacy of 4% articaine lingual subperiosteal injection as the primary injection for permanent mandibular second molars in ...

AIM To investigate differences in the root canal morphology of permanent mandibular molar teeth at various ages. METHODOLOGY Four hundred and eighty permanent mandibular first and second molars were examined. First and second molars were divided into six and five groups, respectively, according to the age of the patient at the time of extraction. Root canal morphology was studied using a clea...

AIM To investigate variations in the root canal systems of first and second permanent mandibular molar teeth in a Sudanese population using a clearing technique. METHODOLOGY Two hundred extracted first and second permanent mandibular molars from three cities in the state of Khartoum were studied. Access cavities were prepared and pulp tissue was removed by immersion in 5% sodium hypochlorite ...

The purpose of this study was to determine the relationship between the sagittal inclination of the first and second maxillary molars and the eruption of the third molars. The sample consisted of 2 groups. The subjects in the first group (n = 28) had complete normal dentitions including third molars; those in the second group (n = 32) had impacted right and left third molars. The sagittal incli...

As part of a large retrospective study of the durability and lifespan of 2229 restorations (1898 amalgams and 331 stainless steel crowns) in primary molars of 226 pediatric patients attending a dental school clinic, the costs associated with first placement and later replacements of the restorations were examined. Individual restoration histories were followed for up to 9 years, computerized, a...

Impaction of the lower second molar is not a common problem, but it is very challenging for both orthodontist and oral surgeon. Treatment options depend on the degree of tooth inclination, the position of the third molars, and the desired type of movement, which may be surgical and/or orthodontic in nature. A good treatment alternative is surgical uncovering with orthodontically-assisted erupti...

INTRODUCTION The purpose of this retrospective study was to determine the anesthetic success of the inferior alveolar nerve (IAN) block, and supplemental articaine buccal infiltration after a failed IAN block, in first and second molars and premolars in patients presenting with symptomatic irreversible pulpitis. METHODS As part of 6 studies, 375 emergency patients presenting with symptomatic ...
