“…The findings of this prospective study provide valuable insights into the potential impact of jaw shape on the response to dental The positive correlation between the mandibular angle and the volume of local anesthetic required aligns with previous research studies [9,10]. Two studies that reported a similar association between mandibular angle and anesthesia response, suggesting that a more pronounced angle may contribute to increased resistance to anesthesia.…”

Objective: This prospective study aimed to investigate the potential impact of jaw shape on the response to dental local anesthesia. Material and Methods:The study design involved the recruitment of 300 patients for 12 months scheduled for dental procedures requiring local anesthesia. Jaw shape measurements, including the mandibular angle, jaw length, and visual assessment of facial morphology, were obtained for each participant. Pain tolerance levels were assessed, and standardized local anesthesia techniques were employed. The effectiveness of local anesthesia was evaluated based on objective measures, such as anesthesia onset and duration, and subjective measures, including pain intensity and patient satisfaction. Descriptive statistics were used to summarize the characteristics of the study population. Correlation analyses, such as Pearson's correlation coefficient, were conducted to assess the relationships between jaw shape measurements and anesthesia response variables. Results:The statistical analysis revealed significant correlations between jaw shape measurements and anesthesia response variables. A positive correlation was found between the mandibular angle and the volume of local anesthetic required (r = 0.372, p < 0.001), indicating that patients with a more pronounced angle needed higher anesthesia doses. Conversely, a negative correlation was observed between jaw length and anesthesia volume (r = -0.285, p < 0.001), indicating that patients with longer jaws required lower anesthesia doses. Participants with a more pronounced mandibular angle reported higher pain intensity levels (p < 0.05), while patient satisfaction levels were lower among those with a retrusive chin (p < 0.05). Conclusion:This study demonstrates that jaw shape may influence the response to dental local anesthesia. Patients with a more pronounced mandibular angle and longer jaws may require adjustments in anesthesia dosing for optimal pain control. Additionally, specific facial morphologies, such as a retrusive chin, may be associated with increased pain sensitivity.

“…A thorough understanding of the anatomic variation of PM is essential for a safe and successful IANB [ 13 ]. The anatomical structure of the PM is variable and complex and must be always considered during local anesthesia, dental treatment, surgical interventions, and diagnostic procedures [ 14 , 15 ].…”

Inferior alveolar nerve block (IANB) is one of the most common procedures in operative dentistry, and a deep understanding of the normal anatomical variation of the pterygomandibular space (PM) is essential for its safe and successful administration. This cadaveric anatomical study aimed to use A-silicone injections to evaluate the volume of the PM. This study was conducted using 46 human cadaver heads (25 males and 21 females). A craniometric analysis was performed using the cadavers’ ages, the number of silicone cartridges (carpules) used to fill the pterygomandibular space, Izard’s Facial Index (FI), and the Cranial Index (CI). A Halstead mandibular block was performed by injecting 1.7 mL A-silicone cartridges (as an equivalent to standard local aesthetic carpules volume) into the PM. The cured silicone was extracted from the dissected mandibles. The volume (length, width, and thickness) of the extracted silicone and the number of silicone cartridges used to fill the space were evaluated. The results showed that there are statistically significant positive correlations between the CI and the width of the right PM, as well as the width and length of the left PM. A statistically significant correlation was found between the width of the left PM and the age of the cadaveric heads; the higher the age, the thicker the space on both sides. The volume of the PM corresponded to 1.5 cartridges on average.

“…O nervo mandibular é o único ramo misto com atividade motora e sensação, contudo, a maioria dos ramos motores recebe esse nome devido os músculos atribuídos, uma vez que os ramos sensitivos são representados por nervos auricular-temporal, bucal, lingual e alveolar inferior (MAEKAWA et al, 2020). O surgimento do excesso de calor gerado por determinadas ações, por exemplo; Osteotomia com ferramentas rotativas, pois a broca não está fria o suficiente, o que pode ocorrer durante a crioterapia essas são as causas físicas.…”

A extração de terceiros molares é comum ter riscos e complicações no pós-operatório, causando parestesia do nervo alveolar inferior. A localização dos elementos dentários e a conexão com o canal mandibular é um fator que o profissional deve observar e examinar durante o planejamento da cirurgia, pois lesões e danos ao NAI podem trazer consequências permanentes para o paciente. Parestesia, causa a perda da sensibilidade do nervo e ocasionando ao paciente desconforto de forma que pode ser efêmero ou contínuo. Este estudo tem como objetivo abordar as causas da parestesia do nervo alveolar inferior por meio de uma revisão de literatura. A metodologia empregada foi a de revisão de literatura, onde buscas por artigos nas seguintes plataformas de pesquisa: Biblioteca Brasileira de Odontologia – BVS, Scielo, e Pubmed publicados nos anos de 2018 e 2023 em língua portuguesa e inglesa. De acordo com os achados na revisão, diversas modalidades terapêuticas vêm sendo discutidas na literatura com a evolução da Odontologia. Atualmente o padrão ouro de tratamento é a laserterapia com as suas propriedades terapêuticas bioestimuladoras, analgésicos, anti-inflamatórios e medicamentos com propriedades que podem auxiliar restauração de nervos periféricos lesionados.
